Acrylic Fiber
Acrylic Fiber is synthetic Fiber is made of polymerization of acrylonitrile amongst an molecule weight higher upwards 100000, well-nigh 1900 monomer unit. For a called equally 'Acrylic”. Typical Co-monomer are vinyl acetate or methyl acrylate.

Acrylic is defined equally a refers to a fiber containg at to the lowest degree 85% acrylonitrile monomer, piece inwards modacrylic the per centum of acrylonitrile must live less than 85% exactly greater than 35%.
Acrylic Fiber lead keep replaced wool equally it gives same properties equally wool fiber similar warmth, etc..
Acrylic monomer =(CH2=CH-CN) made yesteryear next reaction.

Major Production Of Acrylic Fiber:-

Spinning of Acrylic fiber:

(1). Solution Spinning

Wet Spinning.
Dry Spinning

(2). Melt Spinning
Out of higher upwards techniques wet spinning is to a greater extent than frequently than non prefer for production of acrylic fiber. Above all methods similar moisture spinning, inwards this fiber brand yesteryear using solvents inwards detail coagulation lav mix amongst appropriate per centum of solvent as well as other chemical. This procedure lead keep to a greater extent than fourth dimension to create fiber compare to other spinning methods like, dry out & melt.

Production of Acrylic Fiber:
Here shows production period of time nautical chart of acrylic fiber:-

Acrylic fiber is produced yesteryear gratuitous radical recess polymerization is used as well as production is deport out inwards Dry & Wet Spinning.
