The fabric resists pilling and has a smooth finish that makes it ideal for everyday wear and use. In other words, cotton is not moisture-wicking, which means it doesn't pull the sweat away from the skin. Fibrillation is the longitudinal splitting of a single fiber into microfibers of typically less than 1–4 μm in diameter. During scouring, mercerization and dyeing with reactive dyes, sodium hydroxide or sodium carbonate is normally used. Lyocell has moderate resiliency. Soft, breathable, lightweight and comfortable. The fuzz was mainly generated by mechanical abrasion in dry condition while the fibrillation was induced by mechanical abrasion in wet condition. Lyocell was first developed in 1972 and as a pilot project and was called “Newcell”, later it was commercialized with the brand name Tencel. What does it feel and look like? It's so easy to care for: gentle machine wash and tumble dry on low, steam if preferred. Lyocell manufacturing requires fewer steps compared with viscose rayon fibre manufacturing. Viscose is synonymous with rayon, and the name comes from the honey-like texture that occurs during the manufacturing process. Fibrillation can be generated due to more oriented crystalline regions smaller and more oriented amorphous regions are higher in the fiber structure . How did the colonial governments develop? Less degree of fuzz is formed when the fiber is swollen in wet state as shown in (7). Effect of cellulose pulp type on the mercerizing behavior and physical properties of lyocell fibers. Nicolai M., Nechwatal A. and Mieck K.- P. 1998. After a certain times of Washing & Drying treatments, the fiber/fiber friction in dry gets higher which results suppress of fuzz formation in dry state. The work concluded that formation of Na-cellulose II causes plasticization of the lyocell fibers as both inter- and intra-molecular hydrogen bonds are broken by these higher sodium hydroxide concentrations. 2009 have observed that sodium hydroxide treatment causes the density, orientation and crystallinity of lyocell fiber to decrease with increasing sodium hydroxide concentration, and that the greatest change in fiber properties occurs between 3.0 and 5.0 mol dm-3 NaOH. All Rights Reserved. Fibrillation can be removed by using of specific cellulase enzymes. When fabrics are made from polyester, nylon, lyocell spun yarns, however, the stronger anchor fibers are not easily broken and the pills that are formed are not released quickly from the fabric. Breathable, comfortable, earth-friendly and easy to care for, Tencel is the trade name for lyocell, a fabric manufactured by Lenzing from wood pulp. The fibrillation hardly occurs in dry state (9). Lyocell is subjected to treat with Tetra methyl- ammonium hydroxide (TMAH) will reduce 60% of fibrillation tendency compare to other alkalis. Steps such as the derivatization, alkalization and xanthation of rayon are omitted in the Lyocell process. The fiber/fiber friction was measured as counts of twist to open the yarn until it starts to slip in dry and wet states. The excepted crosslinking in cellulose molecules will be developed. They are essentially small tangles of fiber on a fabric’s surface, formed when the fabric rubs against itself or another material. Lyocell fabric is very well adopted to cold temperature and one of the best natural fabrics to keep your warm in the winter weather for all your outdoor activities. You won't get sweaty under there as the material is good with moisture! ¿Cuáles son los 10 mandamientos de la Biblia Reina Valera 1960? it actually gets softer the more you wash it; it also does not pill as fast at cotton. Submerge the item and gently agitate the water with your hands to evenly distribute soap. Textile manufacturers like the fact that it's easy to mix this fabric with other types of textiles; for instance, it plays well with cotton, silk, rayon, polyester, nylon, and wool. Textile Res. Although microfiber fabrics tend to wick moisture away from the body, they do trap body heat too. Tencel however, is made from wood pulp and Lyocell, what ettitude bedding is made from, is instead made from bamboo pulp. Removal of the fibrils is absolutely imperative and this is done by using any one of the following methods. Effect of Fiber Swelling on the Structure of Lyocell Fabrics. Okubayashi S. and Bechtold T. 2004. Secondary fibrillation produces change in hand as well as appearance of the fabric. Textile crosslinking reactions to reduce the fibrillation tendency of lyocell fibers. Modified fibrillation behavior of solvent-spun cellulose fibers by the reaction with reactive dyes. Within the solvent spinning process that produces Tencel®, a closed loop circuit recovers, purifies and reuses the solvent up to 99.5 percent, yielding very little by product. 73(6): 541-545.12. Tencel is like Lyocell but is an Austrian trademark and with this you can be sure the wood used is FSC certified. Background Fibrillation of lyocell and other regenerated cellulosic fibers occurs during its wet processing and usage. Angew. Compared to unmercerized cotton  & lyocell except with a fewreactive, vat, and direct dyes to produce heavier depth by exhaust methods. Fibrillation mostly leads to pilling and therefore spoils fabric appearance and touch Pill formation is a common problem mainly in knitted fabrics made not only from synthetic fibers but also from natural fibers, man-made cellulosic’s and their blends because no consumers accept the undesirably pilled garments. Doesn’t pill. Our HyggeB quilt cover is made from this luxurious fabric named 100% Organic Bamboo Lyocell which has this silky smooth and feathery soft texture from day one. During the plasticization state of lyocell can be caused to reduce the fibrillation tendency up to 40 %. At the same time, lyocell’s moisture management does not give bacteria a chance to grow. doi:10.1111/j.1478-4408.2004.tb00233.x. This parameter is obviously central in determining the practical color value of a particular product20. But mostly reactive dyes are used for achieving dual functions such as dyeing and reducing degree of fibrillation. Other than the mechanical effect, the factors that increase fibrillation are low yarn twist, open structure, high temperature, alkaline pH, low liquor ratio , etc. Tencel/Lyocell CleanBamboo™ are both wood-based cellulose fibers, both made from wood pulp. Melliand Textil berichte 79(3): 155-156. The pilling was greatly accelerated by a combination of fuzz formation caused in dry state and fibrillation in wet state. Pills are masses of tangled fibers that appear on fabric surfaces during wear or laundering. HyggeB 100% Organic Bamboo Lyocell duvet cover will make your extra 5 minutes in bed so worth it, you’ll never feel sorry for arriving late for school/work. Figure: 2. Due to the unique highly crystalline structure of lyocell, and weaker lateral links between the crystallites, the fibers undergo localized separation of fibrous elements at the surface known as fibrillation, mainly under conditions of wet abrasion. Generally additional reactive groups do offer the important benefit of potentially increasing the fixation of a dye. A schematic mechanism of pill formation during Washing & Drying treatments. Lyocell explained: What it is, how it's related to tencel, and how to care for these fabrics! Textile Chemist and Colorist 28 (5): 24-27. The MSDS (Material Safety Data Sheet) for. J.,  75 (4), 288- 292, 2005. Lyocell is subjected to treat with Tetra methyl- ammonium hydroxide (TMAH) will reduce 60% of fibrillation tendency compare to other alkalis. The secondary form, produced deliberately, is responsible for the fabric’s attributes. Increase in fiber/fiber friction in dry state, decrease in degree of swelling might lower tendency of pill formation as well as fibrillation. Certain reactive dyes, which have at least two reactive groups, can form a covalent bond with two adjacent cellulose molecules 20. The fibrils formed can be so fine that they become virtually transparent and give a frosty appearance to the finished fabric . Fig 1: Example of a fibrillated (A) and non-fibrillated (B) lyocell fiber. Lyocell has an extremely smooth, soft surface that drapes beautifully to flatter every figure. On the other hand, the factors that decrease fibrillation include reduced mechanical action, use of crease mark reducing agents, singeing before or after dyeing, cellulose enzymatic treatment and finishing with resins. Lyocell is een zeer duurzaam materiaal, gemaakt van cellulose uit houtsnippers. In this paper we have discussed about the mechanism of pill formation in lyocell fabric including fuzz formation and fibrillation,Mechanism of pilling formation and Defibrillation methods for Lyocell; the influence of fiber swelling on fibrillation tendency of lyocell fiber was also discussed in this paper. It doesn't get drawn away from your skin. Ibbett R. N., and Hsieh Y. L. 2001. Lyocell is subjected to treat with Tetra methyl- ammonium hydroxide (TMAH) will reduce 60% of fibrillation tendency compare to other alkalis. The fibrillation was retarded with alkali treatment in aqueous NaOH and KOH solutions at concentrations between 3.0 and 7.0 mol/l, and minimized at 5.0 mol/l where the uniform reorganization of macrofibrils was observed with scanning electron microscope. Loose fibers are pulled from yarns and are formed into spherical balls by the frictional forces of abrasion. Tencel however, is made from wood pulp and Lyocell, what ettitude bedding is made from, is instead made from bamboo pulp. Drying, easy to pill The fibril number of lyocell fiber treated in trimethylammonium hydroxide was enhanced with increasing concentration and weight loss. Structure formation of regenerated cellulose materials from NMMO-solutions. Firstly a fiber end comes out from the inside of a yarn by a mechanical abrasion during Drying treatment, which induces the fuzz (1). rope marking defect in hank finishing, graying of dyed fabrics and a change of handle of clothes that spoils garments features. Finishing of knit goods produced from Lenzing Lyocell. To get around this – wet/chemical processing has to take place to control the surface of the fibre – organicclothing.blogs.com 35% Cotton, 65% Polyester 2 CAUSES Rohrer C. Retzl P. and Firgo H. 2001. 256: 21-27. HyggeB 100% Organic Bamboo Lyocell quilt cover will make your extra 5 minutes in bed so worth it, you’ll never feel sorry for arriving late for school/work. Reason for Fibrillation Add 2 capfuls or a squirt of Delicate Wash to a washbasin or sink filled with cool water. A                                                                     B Lees hier verder over de voordelen voor jou als duurzame mode liefhebber en ook over de duurzame nadelen van lyocell die in het productieproces naar voren komen. Commercially, it was found any one of the following methods used for control the degree of fibrillability. Color Technol 123:387–393, Bates I, Mauchru E, Phillips DAS, Renfrew AHM, Su Y, Xu J (2004) Cross-linking agents for the protection of lyocell against fibrillation: synthesis, application and technical assessment of 2,4-diacrylamidobenzenesulphonic acid. Tencel is simply a brand name of a type of Lyocell CleanBamboo™. LYOCELL BAMBOO WE’VE SAID GOODBYETO COTTON ANDSYNTHETIC FIBERS. Conclusion Choosing sheets for yourself may not seem like a difficult task initially, but if you want comfortable bed sheets that will last a long time, you may have to do some extra research. Fabrics with pills have an unsightly appearance and unpleasant handle2. Soft, breathable, lightweight and comfortable. Lyocell fiber have some key characteristic over other cellulosic fibers; such as high dry and wet tenacity, high wet modulus and etc., meanwhile lyocell have few disadvantageous formation of fibrillation under wet condition. Tencel fiber，also called "Lyocell fiber"，is a natural environment-friendly fiber made of wood pulp fiber after physical treatment. Not all Lyocell is equal, however. Perfect, isn’t it? Crosslinking reactions of spunwet NMMO fibers and their influence on fibrillability. This tendency to pill just adds more work to your laundry schedule so it is always best to hang dry the material and protect your fabric from two weaknesses. Herein, is lyocell a good fabric? doi:10.1016/j.eurpolymj.2008.10.030. The first thing that you want to take into account is the thread count. Soft, breathable, lightweight and comfortable. Naturally, two properties of lyocell are that it doesn’t always accept dyes well, and it has an inherent tendency to fibrillate or “pill”. 100% Cotton. J. The fibrillation is inhibited by not only prevention of fibril separation but also modification of fiber surface, resulting in decrease in surface friction and water accessibility. The MSDS (Material Safety Data Sheet) for lyocell rates the amine oxide solvent used to digest the wood pulp as being non-toxic and about 99% is recovered and recycled during the manufacturing process. Dyeing with Poly Functional Reactive Dyes The inducement of pill formation from fuzz is significantly hindered without wetting (6). Textile Res. It is one of the important properties of Lyocell. Polym. " Tencel does use less land and water than cotton production," Edward Hertzman, the publisher of Sourcing Journal, which focuses on the retail … As of 2010, Lyocell is more expensive to produce than cotton or viscose rayon. Our HyggeB duvet cover is made from this luxurious fabric named 100% Organic Bamboo Lyocell which has this silky smooth and feathery soft texture from day one. The fabric absorbs dye in warm water and does not bleed dye during the laundering process. Click to see full answer. 26: 1473-1524. However, if the dye is Poly-functional, i.e. Conclusions Lyocell is a type of rayon fabric that is made from dissolving cellulose or wood pulp using an innovative spinning process. Not only does it provide a feeling of well-being, but it also makes it non-irritating, even for sensitive skin. The swollen soft fiber is easily fibrillated by mechanical abrasion during Washing and Drying treatments (3) and then tangled each other, which develops pilling (4). Chae D. W., Choi K. R. and Kim B. C. 2003. 10 page 21-24 (2001). Does Lyocell Fabric Shrink When You Wash It? T. hese hairs on the fiber surface are called fibrils. The truth is it is the same thing! Many reports on themorphological structure of man-made cellulosic fibers and their treatment with crosslinking agents have been published . The effect of sodium hydroxide treatment on crystallinity in the cellulose II of lyocell, modal and viscose, and followed this with a separate study comparing lyocell, acid-hydrolyzed lyocell, and standard crystalline cellulose II Recently, Goswami et al. The cross linking of reactive groups of these dyes with adjacent cellulose chains provides an opportunity to reduce fibrillation during wet processing. Cotton. R. S. Blackburn-Biodegradable and sustainable fibers- Woodhead Publishing Limited and CRC Press LLC © 2005. In view of this, it is necessary to examine the effect of different types of alkali (Sodium hydroxide (Na OH) , Lithium hydroxide (Li OH), Potassium hydroxide (K OH), Tetra methyl- ammonium hydroxide (TMAH) at room temperature on Lyocell fibers. Lyocell's smooth fiber surface feels soft and supple against the skin and its incredible wicking abilities keep the skin dry, making lyocell a great fabric for sensitive skin. It does not wrinkle as badly as rayon, cotton, or linen, and some wrinkles will fall out if the garment is hung in a warm moist area, such as a bathroom after a hot shower. Waste products in the air and water from the manufacturing process are minimal and considered harmless. 3. It is hypoallergenic and doesn’t cling. De houtsnippers komen van eucalyptus- of beukenbomen uit speciale bossen … 256: 21-27. A Hunter M Renfrew-Reactive Dyes for Textile Fibers: The chemistry of activated p-bonds as reactive groups and miscellaneous topics Society of Dyers and Colourists1999. H.-P., Weigel P., Purz H. J. and Ganster J. Fink. In lyocell pill generation mainly occurred due to fibrillation only. Fundamentally bilateral reaction provides the opportunity of cross linking cellulose molecules. The fibrillation was retarded by crosslinking with 1,3-dimethylol-4,5-dihydroxyethylene urea and by treatment with amino functional polysiloxane accompanying decrease in water retention capacity. Textile Today is a regular publication of Amin & Jahan Corporation Ltd. It’s a comprehensive magazine for textile, apparel & fashion industry. Of course, this is far from being the only differentiation criteria but, the higher the thread count is, … Because of the technology required, it simply costs more to produce, which transfers to shoppers, leading to Tencel's perception as a luxury fiber. Enzymatic Treatment: Goswami P, Blackburn RS, El-Dessouky HM, Taylor J, White P (2009) Effects of sodium hydroxide pre-treatment on the optical and structural properties of lyocell. Soak for up to 30 minutes. It also has a luxurious sheen. Lyocell tends to be softer than cotton. In wet processes the surface of lyocell fibers begins to peel away. Lyocell also has attractive environmental benefits. Carbohydrate Polymers 58(3): 293-299. Modified fibrillation behavior of solvent-spuncellulose fibers by the reaction with reactive dyes. Fabric composition: Wood cellulose and synth. During the plasticisation state of Lyocell can be caused to reduce the fibrillation tendency up to 40%. This was attributed to the onset of formation of sodium (Na)-cellulose II at 3.0 mol dm-3 NaOH; a fully formed Na-cellulose II structure was observed above 6.8 mol dm-3 NaOH. Perfect, isn’t it? Lyocell may be blended with a variety of other fibres such as silk, cotton, rayon, polyester, linen, nylon, and wool. Okubayashi S., Griesser U. and Bechtold T. 2004. The fact that it is man-made with botanic or natural origin. Enzymes will not prevent the recurrence of fibrillation of fibers but, in conjunction with optimum processing procedures. Correspondingly, is lyocell better than cotton? 1 Assistant Professor-Textile Chemistry, DKTE'S Textile Engineering Institute, Ichalkaranji, MH, India, 2Assistant Professor, Department of Textile Engineering, Daffodil International University, Bangladesh. Textile Res. A Pilling Mechanism of Man-Made Cellulosic Fabrics – Effects of Fibrillation. Want laten we eerlijk zijn, niet alle duurzaam beschouwde stoffen hebben alleen maar een zonnige kant. laundry. contains more than four reactive groups, a further opportunity exists for fixation. 71(2): 164-173. This effect is of particular interest of fibers with high fibrillation. Nemec H. 1994. 2. What is the best fabric to wear in hot humid weather. Bredereck K., Stefani H.-W., Beringer J. and Schulz F. 2003. Alkali Treatments Lyocell’s smooth fiber surface feels soft and supple against the skin and its incredible wicking abilities keep the skin dry, making lyocell a great fabric for sensitive skin. Pilling is a phenomenon exhibited by fabrics formed from spun yarns. The cross-linking of the cellulose chains in the fiber in a never dried state result in specific morphological properties of this fiber is then chemically cross-linked in an additional finishing step23. Resins which can crosslink with the fabric are frequently used after dyeing. It is particularly cool and smooth, and great at wicking sweat away from the body. Het is dus een natuurvezel. © AskingLot.com LTD 2021 All Rights Reserved. Reactive dyes were introduced 40 years ago, today modern dyestuffs with several reactive groups, which were originally developed for higher wet fastness and better bath exhaustion. As Lyocell is   a cellulosic fiber, it can be dyed with colors normally used on cotton. Lyocell is a new generic name given to a cellulosic fiber which is produced under an environmentally friendly process by dissolving cellulose in the tertiary amine oxide n-methylmorpholine-n-oxide (NMMO). Tencel branded Lyocell is different than of generic Lyocell. Similarly, you may ask, is lyocell a good fabric? In de Sophie Stone collectie vind je het materiaal lyocell. Tencel lyocell and modal fibers are known for their softness and sustainability features. It is used in many everyday fabrics. The pilling was formed only on the fabric treated with wash and dry treatments. Viscose is spun with carbon disulfide to form its fibres—unfortunately, carbon disulfide is incredibly volatile and is easily released into the environment, causing damage to the health of textile workers and the surrounding environment. There are two forms of fibrillation – primary and secondary. These balls of tangled fibers are held to the fabric surface by longer fibers called anchor fibers. Wat zijn precies de voor- en nadelen van lyocell? It is also believed that the presence of several reactive groups is not alone sufficient to produce this effect, but very specific molecular constitution and properties are also required to get the said effect . The critical degree of swelling for lyocell fiber with no fibrillation was 0.45 cm3/g in ethanol/water mixture. Not only is it cheap and hugely available, but it is also great for the heat. There have been many studies about pilling mechanism for knitted fabrics, which described influences of selected fiber properties e.g. A kinetic study of moisture sorption and desorption on lyocell fibers. Basically fibrillated lyocell shows lower visual color yield in comparison with non-fibrillated lyocell (lyocell LF), independent of exhaustion and fixation . What is internal and external criticism of historical sources? Specific multifunctional reactive dyes are reported to have favorable effect on fibrillation behavior of Lyocell fiber. Yi-Jun Pan, Chien-Kuo Yen- Cellulosic Fabrics – Effects of Fibrillation. Textile Res. This softness is due to a very smooth surface. It falls between synthetic and natural fibers referred to as regenerated cellulose fiber. It pre-treatment is most important stage in chemical processing of different cellulose fibers and blends is response of these fibers to treatments involving alkali at different concentrations. Textile Res. Does lyocell fabric have pills? As we know, Lyocell CleanBamboo™ is produced using a closed loop system which has minimal impact on the environment and maintains economical use of … It does not promote quick drying of sweat. From its inception Textile Today has already created a good impression and strong reputation in global market. Unlike lyocell’s lesser sisters viscose and bamboo, lyocell doesn’t require the use of toxic carbon disulfide in its processing. This means that the tendency towards fibrillation is prevented by the introduction of additional linking agents between the cellulose molecules. Rayon, modal, lyocell, and cupro are semi-synthetic fabrics that are extremely versatile. This fibrillation behavior restricts the applications of lyocell; in particular, fabric dyed in dark hues, as medium/heavy depths can develop a ‘frosty’(greying) appearance caused by very fine fibrils that are visually transparent. From a consumer's perspective, Tencel is also more expensive. Lyocell can have many different textures, but the basic fabric is soft to the touch. It is used in virtually everything from denim to towels, lyocell sheets, and other bedding, causing many to wonder, does lyocell shrink or wrinkle? lyocell/tencel: The difference from viscose is that Lyocell and Tencel are made in a closed loop system, so the chemicals are recycled. Tencel soaks and pills easily. Versatile This eco fabric has controllable fibrillation (the very fine hairs found on the outer fibres), which can be manipulated into everything form suede-like softness to a silky smooth finish. Don't take this the wrong way: microfiber sheets do offer a warm and comfortable sleeping experience. Key words: Alkali treatment, crosslinking, Defibrillation, Enzymatic Treatment, Fibrillation tendency, fuzz, pilling, Polyfunctional reactive dyes, weight loss. They have proved very comfortable to wear, are durable and retained their ‘as new’ aesthetic. If anyone has any feedback or input regarding the published news, please contact: @2020 - Textile Today. al High Durable Cellulosic Textiles – Strategies For High Resistance To Fibrillation And Pilling-Lenzinger Berichte, 85 (2006) 98-106. Man-made cellulosic fibers are hygroscopic materials and their structures of fiber, yarn and fabric dramatically change by swelling with polar solvent such as water. Angew. J., 75 (4), 288- 292, 2005. J. 66(9): 575-580. Treating with Cross Linking Agents Indian J Fiber Text Res 29:483–492, Goswami P, Blackburn RS, Taylor J, Westland S, White P (2007) Dyeing behav lyocell fabric effect fibrillation. Tencel fibers are used for clothing, sheets, towels and drapes. Basically fibrillation can be controlled by changing the various spinning parameters such as spinneret size, temperature, draw ratio, air gap conditions and after treatment of the fiber. The pilling is promoted by lower fiber/fiber friction in dry state and higher fiber/fiber friction caused by higher fiber swelling in wet state. Also Know, are Lyocell and Tencel the same? There are different types of rayon. Cotton is one the best fabrics for hot weather. Lyocell is a more specialized, innovative fabric. Nechwatal A., Nicolai M. and Mieck K.- P. 1996. Makromol. Chem. The first one consists of long and irregular fibrils which can get entangled, leading to an extremely matted appearance. As a result, clothing made of lyocell remains odor-free for multiple wearings and much longer than cotton. Joonseok Koh- Dyeing Properties of a Mixed Bi-Functional Reactive Dye on a Novel Regenerated Cellulosic Fiber- IJFTR March 2005 Pp 88-93. What is tencel fabric？ Custom Fitness … These two fibers originate from the pulp of plants that are immobile, and survive on auto managing variations in heat and cold! Brauneis F. and Eibl M. 1998. Few chemicals are used, among which N-methyl morpholine-N-oxide (NMMO) and water are almost recycled, which makes the process economically favourable (Rosenau et al., 2001; Dawson, 2012). Melliand Textil berichte 12: 58-64. tensile strength, elongation, bending rigidity, fiber count, shape of fiber cross-section and friction on the pilling phenomenon. Color fast. DEFINITION OF LYOCELL In short: It is a form of rayon which consists of cellulose fibre made from wood pulp or cotton linter. Find patient medical information for Lycelle topical on WebMD including its uses, side effects and safety, interactions, pictures, warnings and user ratings. Unlike most forms of rayon, modal is much less likely to shrink in the wash. Biodegradable. Defibrillation and methods J. M. Taylor, M. J. Bradbury and S. Moor house, “Dyeing Tencel and Tencel A100 with Poly-Functional Reactive Dyes”, AATCC Review, No. THE FASHION INDUSTRY The fashion industry is considered to be one of the most pollutive industries in the world, with total greenhouse gas emissions from global textile production of 1.2 billion tons per year. Handwashing is always the best and safest method for washing lyocell. These fibrils are short and even, and cannot cause pilling. When cleaning tencel, do not soak or wash it for too long. Color Technology 120:293–300. Fabrics like bamboo and lyocell are the most breathable and therefore the most ideal to keep warmer in the winter cold and cooler in the hot summer. Introduction: Lyocell fabric is very strong whether it is wet or dry, and it is more resistant to pilling than cotton. Discover how … Erring on the side of caution is always good when it comes to delicate fabrics like Tencel lyocell. Processing of lyocell is more technically challenging in fabric and garment form compared to other regenerated cellulosic fibers due to fibrillation,and for overall success in the textile industry, it is important to understand the dyeing behavior of fibrillated lyocell thoroughly to overcome this problem. This process is particularly suited to woven fabrics as these are prepared and dyed open width and so are free of fibrillation before dyeing. J. Lyocell is the third generation of rayon processing technology. This structure is responsible for the high fiber tenacity but low lateral cohesion, especially when subjected to mechanical stress in the swelled state.
