Manufacturing process of nylon fibers and nylon yarns

Manufacturing nylon fibers and nylon yarns, as explained in the following: 

This is a chemical process to produce the nylon polymer using caprolactum and acetic acid.

The nylon rope produced from the polymerization process is cut into chips.

In this stage nylon chips are melted to reach the viscosity suitable for pumping to the spinning process. 

In this process, molten nylon is pumped to spinnerettes, and the polymer streams coming out are cooled by blown air that let the polymer solidifies and form continuous nylon filament.

Drawing and twisting
The nylon yarn produced in the previous process is subjected to stretch, is given twist and is
wound on a bobbin .

This process subjects the filament yarn to heating, then inducing crimp in the filament and then cooling the filament, thus forming a textured nylon yarn.

Drawing and crimping
This process (for fibre production) is in the production line of nylon fiber in which filament tows from spinnerettes are collected to form a sheet which is subjected to stretch and crimping to give the required degree of crimp and fineness. 

Cutting and pressing
In this process the collected tows of nylon filaments pass through a cutting machine which cuts the filaments into fibers with length similar to wool fibers. The resulting nylon fibers are pressed into bales with polyethylene cover
