Acrylic Fibers are oil resistant synthetic Fibers

Acrylic fibers are synthetic fibers derived from polyacrylonitrile. By the process of free radical polymerization, the polymer for the acrylic fibers is formed. During polymerization process of chemical reaction, three-dimensional networks of polymer chains are formed. These polymer chains are then treated with polymer solvents such as N, N-dimethylformamide or aqueous sodium thiocyanate resulting in the formation of Acrylic Fibers. The newly formed fibers are then made to pass through multi-hole spinnerette which squeezes out these thin lined threads like fibers which are again treated with the same solvents used before.
The raw fibers formed are further made to pass through four steps before the final fibers emerge. Let's see these steps in short.
1. Washing a?? The fibers are washed by dipping them in chemical solvents like aqueous sodium thiocyanate and allowing them to remain there for around 5 minutes before proceeding to the next step.

2. Stretching a?? The fibers are stretched using highly sophisticated scientific machines which pull them to their tension limit when it may simply break off.

3. Drying a?? The stretched fibers are then passed through blow-air machines which help in drying the product.

4. Crimping and Cutting a?? Finally formed fibers after drying are straightened using crimping irons which help them to form straight fibers which are then cut according to industrial standards.
Acrylic fibers are usually modified to create special properties best suited for their end-uses and are unique because of their uneven surface.
