Viscose Rayon Manufacturing Process
What
is Viscose Fabric?
Viscose
Rayon is obtained from the viscose process made from cellulose fibres to
produce regenerated fabric. In this process, the solution of wood pulp is
turned into fabric. It has a smooth texture close to silk. It is popular since
the late 1800s. Viscose has low production cost and it is widely used for
clothing, feminine hygiene and household stuff.
Why is it preferred?
Viscose is the best alternative to cotton during the
summer and spring season when one needs a lightweight and soft material. It gives
an extravagant look at low prices. for a much lower price point. It has the
property to blend with other fibres such as cotton, spandex and polyester.
It is widely used
for the mentioned reasons:
●
Breathable-It’s
convenient for temperate weather clothing and feels light as it does not stick
to the body.
●
Absorbent-
Viscose rayon is sweat absorbent and does not trap heat. It is perfect for
sportswear and daily clothing.
●
Lightweight-
Viscose rayon is notably windy, which makes it likeable for shirts and summer
dresses.
●
Maintains
Shape- This fabric can be blended with other textiles like spandex to add the
stretch
●
Soft-The
texture of the material is soft like silk.
●
Fast dying
material- Viscose retains the die and does not fade even after regular use.
How does Viscose fabric make?
Chemicals
like sodium hydroxide and carbon disulfide are involved in the viscose process,
hence it is semi-synthetic. Semi-synthetic is the most used fabric in summers.
It is made up of wood pulp from eucalyptus, pine, beech and bamboo trees which
are rapidly renewable plants.
The viscose manufacturing process can be summed up in the
following five steps:-
Wood pulp is
dissolved in the chemicals. |
↓
Wood pulp is
washed and bleached. |
↓
Viscose
fibres are created by treating the pulp with carbon disulfide and later
dissolved in sodium hydroxide. |
↓
Viscose
filaments are created by forcing the solution through the spinneret and
called regenerated cellulose. |
↓
These
regenerated cellulose fibres are then spun into yarn. |
Now, these yarns are woven or knit into
viscose rayon fabric.
