Introduction of Tencel Fiber:
Tencel is a brand name for a set of fibers called lyocell and
modal. These fibers are known for feeling super soft and are
widely used in sustainable fashion. Tencel is somewhat
similar to rayon because they’re what the industry refers to
as “regenerated cellulose” fibers. Manufacturers take wood
pulp, dissolve it in a chemical solvent, then push it through
an extruder to form the fibers.
Tencel has very good properties, such as high tenacity
and low elongation. It has a high moisture regain of
11.5% and at the same time retains tenacity well when
wet. The drawback of lyocell is that the fiber can split
quite easily. Lyocell, modal and polynosic rayon have
very similar properties, so their end uses are also similar.
Properties of Tencel Fiber
1.The actual degree of polymerization in the tencel fibers
is higher than for standard viscose, modal (HWM) or
polynosics.
2.Tencel fibers have excellent wet strength and wet
modulus. The high wet modulus of the fiber is an
important attribute as it imparts Tencel fabrics with very
low potential shrinkage in wet state.
3.The fiber is round in cross-section and has a natural
high lustre.
100% biodegradable.
4.Tencel has a very high absorption capability, a unique
nano-fibril structure and a very smooth surface.
A Comparison of Tencel Fiber
Properties
Manufacturing Process of Tencel Fiber
Tencel manufacturing requires fewer steps compared
with viscose rayon fiber manufacturing. Steps such as the
derivatization, alkalization and xanthation of rayon are
omitted in the Lyocell process.
Few chemicals are used, among which N-methyl
morpholine- N-oxide (NMMO) and water are almost
recycled, which makes the process economically
favourable.
Tencel fiber is a solvent spun fiber using amine oxide
(MMNO) as the solvent. In the process, amine oxide is
heated and is then used to dissolve wood pulp. A very
clear but very viscous solution is obtained which is
filtered and then spun into a bath containing a dilute
aqueous solution of solvent. The bath removes the amine
oxide from the fibers. The fibers are then washed and
dried. The removed solvent is reclaimed for further use.
Blending of Tencel :
Tencel fibres blend well with other natural or synthetic
fibres such as below:
1.With cotton, it softens, adds strength and increases
performance.
2.With linen, it reduces creasing and increases softness
and strength without detracting from linen s own
character.
3.With wool, it preserves the wool aesthetic while
contributing washability, softness and subtle lustre.
4.With polyester or nylon, it lends a more natural hand,
increasing comfort and breathability without diminishing
performance.
5.With lycra, it augments the feeling of comfort and ease.
6.With silk, it affords an even more luxurious hand and
improves performance.
7.The blends adds drape, comfort and performance,
enhance the aesthetics and functionality of fabrics. The
blend also yields high tear and tensile strength.
Advantages of Tencel Fiber
1.Eucalyptus grows on arid land, on which it’s
impossible to plant other crops.
2.Wood comes from certified responsibly managed
forest.
3.Requires no irrigation water.
4.Grows without the need for insecticides or
pesticides.
5.Easy to dye and wash.
6.Comfortable and soft.
7.Excellent moisture management.
8.Biodegradable
9.Great for sensitive skin
10.Naturally anti-bacterial
Disadvantage of Tencel Fiber
1.Tencel will shrink (approx. 3%) after its first
washing but retain its shape after that.
2.Tencel is more expensive than most eco fabric
alternatives.
3. the price of Tencel fabric is more expensive than
cotton fabric, but cheaper than silk fabric
Uses of Tencel Fiber
1.The early stages of the commercialisation of tencel
were focused towards the fashion textile apparel sector.
However, this has changed during the first years of the
twenty-first century so that tencel is now targeted
equally into the industrial sector, with particular
emphasis on the key nonwovens markets of wipes,
filters and feminine hygiene products.
2.Tencel is usually used as a substitute for cotton or
silk. This fabric feels like soft cotton, and it is used to
make everything from dress shirts to towels to
underwear.
3.Tencel fiber is used in women’s wear, denims, suits, etc.
In men’s wear, it is used as golf shirts. It is also used in
the manufacture of towels, sheets, upholsteries and pillow
cases.
4.Industrial uses of Tencel are conveyor belts, ultra–low–
tar cigarette filters, printers blankets carbon shields,
specialty papers and medical dressings.
5.It is used in technical fabrics in which high strength
coupled with high absorption are required. It is also used
in battery separation and coating substrates.
