Give the correct sequence of manufacturing acrylic fiber
(A) Dissolving

(B) Filtering

(C) Spinning

(D) Polymerization

(E) Stretching

Choose the correct answer from the options given below:

Correct option is A

Acrylic fiber is a synthetic fiber made from polyacrylonitrile and is manufactured through a multi-step chemical and mechanical process. The correct sequence of its production is:
1. Polymerization (D):
· The process begins with polymerization, where acrylonitrile and other monomers undergo chemical reactions to form acrylic polymer chains.
2. Dissolving (A):
· The polymer is then dissolved in a suitable solvent, creating a spinning solution (dope) for fiber formation.
3. Filtering (B):
· The spinning solution is filtered to remove impurities or undissolved particles, ensuring uniformity in fiber production.
4. Spinning (C):
· The filtered solution is extruded through spinnerets using wet spinning or dry spinning methods to form continuous filaments.
5. Stretching (E):
· The fibers are stretched and oriented to improve strength, elasticity, and molecular alignment, making them suitable for textile applications.
Information Booster:
· Acrylic fibers are widely used in knitwear, upholstery, and winter clothing due to their wool-like texture and lightweight nature.
· Stretching enhances fiber strength, improving durability and resistance to wear and tear.
