Tencel Fibre is a natural, man-made fiber. It is the trade name for the generic fiber Lyocell. Tencel is a solvent cellulose fibre developed by Courtaulds.
Tencel is composed of 100% cellulose and is a fully biodegradable fibre. It is an exceptionally strong fibre; in a dry state, it is significantly stronger than other cellulosic, including cotton and approximates the strength of polyester.
It does not shrink much when wet and fabrics and garments made of Tencel demonstrate very good stability when washed.
Important properties of Tencel Fibre
a) Comfortable/ Comfortness to the Wearer
Similar to rayon in feel. Soft, breathable, lightweight and comfortable. It is also shrink-resistant, durable and easy to care for. It is an exceptionally strong fiber, both wet and dry
b) Color-rich/ Good Dye Absorption
Tencel was created with color in mind, because of the fibers’ high absorbency. The fabrics can be dyed to high-quality standards.
c) Easy to Care
Made from the natural cellulose found in wood pulp. Produced in a non-chemical manner, the fiber is economical in its use of energy and natural resources and is fully biodegradable.
e) Fibrillation of Tencel Fibre
One of the properties of Tencel is its potential to fibrillate.
Fibrillation is where the wet fiber, through abrasive action develops micro-fibrils (or tiny fibers) on its surface. By manipulating or controlling fibrillation, a variety of different fabric finishes may be achieved.
The surface fibers of standard Tencel are fibrillated to produce a luxurious, soft-touch fabric with a peach skin surface. This is the usually recognized quality of the fiber.
Types of Tencel Fibre
There are currently two types of branded Tencel lyocell.
- Standard fibrillating Tencel
- Tencel A100 (a non-fibrillating variant)
1 Standard Tencel
Fibrillation is unique to standard Tencel. It creates Tencel’s special, luxurious hand. Manipulating or controlling fibrillation produces a wide variety of aesthetics, from a soft, suede-like or peach-touch surface to one that’s clean, smooth and silky.
2 Tencel A100
Tencel A100 is a non-fibrillating variant of Tencel. Its aesthetic is different from standard Tencel’s, but it has the same, unparalleled performance.
Activewear and intimate apparel, as well as knitwear and woven for shirting, sportswear, and home furnishing textiles.
Tencel may be readily dyed with conventional cellulosic dyeing dyes such as direct, reactive, vats, sulfur and azoic Dyes.
Tencel is marketed in all traditional viscose consumer end uses, as well as newly emergent products in both textiles and non-woven sectors which demand high-performance raw materials.
Care Of Tencel Fibre
Delicate fabrics may be hand-washed in cold water with a gentle detergent. Drip dry. Tencel will shrink about 3% with the first washing and will resist shrinking from then on.
Machine washing, using the gentle cycle, is appropriate for many garments (read the garment care label), and drip drying is preferable to machine drying. If line dried, you can briefly toss in the dryer with a damp towel to soften the fabric.
If you must touch up the garment with an iron, use a warm iron only. Too much direct heat may scorch the fabric.
Dry-clean Only: Some garments have a “dry-clean only” label. This is often due to other fabrics used as finishing details or structuring elements, such as linings, in the garment.
The lining, for example, may shrink more than the Tencel fiber which could cause puckering if washed in water. The best course is to understand the washing requirements before purchasing the garment.
This is the newest cellulosic fibre and a new brand name is the world of apparel and textiles; this fibre is very similar to rayon in appearance.
The major difference between lyocell and rayon is that lyocell is much more durable and has a much stronger wet strength. It is also machine washable and dryable.
Production of Lyocell Fibers
Raw cellulose is directly dissolved in an amine oxide solvent. The solution is filtered, extruded into an aqueous bath of dilute amine oxide, and coagulated into fibre form.
Important Characteristics of Lyocell
- Lyocell fibre is Soft, strong, absorbent.
- Fibrillated during wet processing to produce special textures.
- Lyocell fibre has Excellent wet strength.
- Wrinkle resistant.
- Very versatile fabric dyeable to vibrant colors, with a variety of effects and textures.
- Lyocell fibre is hand washable.
- Simulates silk, suede, or leather touch.
- Good drapability.
Major applications of Lyocell FIbre
Lyocell fiber is widely used in Apparel – dresses, suits, sportswear, pants, jackets, blouses, skirts.
Triacetate is a manufactured fiber produced from cellulose triacetate in the forms of filament yarn, staple, and tow.
Cellulose triacetate fiber differs from acetate fiber in that during its manufacture the cellulose is completely acetylated whereas acetate, which is diacetate, is only partially acetylated.
The FTC notes that a fiber may be called triacetate when not less than 92% of the hydroxyl groups are acetylated. Fabrics of triacetate have higher heat resistance than acetate fabrics and can be safely ironed at higher temperatures.
Properties of Triacetate Fibre
- Triacetate Fibre is Shrink and wrinkle resistant.
- Triacetate Fibre is easily washable.
- Fabrics made from triacetate fibers maintain pleat retention and a crisp finish.
- Develop their most valuable characteristics by heat treatments that are included as a part of their normal finishing.
