Manufacturing characteristics of aramid fiber

Manufacturing characteristics of aramid fiber

For the manufacture of Kevlar threads with material properties, plastic is produced, which is subjected to high temperatures, under the influence of which the composition acquires a sticky texture. It passes through a spinneret, from which long, strong fibers grow out of the orifices. They are wound on drums and then cut into length elements from which the stiff fabric is woven.

The owner of the patent produced 29 and 49 Kevlar modifications, with other types of fabrics made to order. This is because they have not gained popularity because they are specific and applicable to a narrow field of activity.

In the manufacture of Kevlar fibers, both the technology and the finished product meet certain requirements. To ensure that it meets all characteristics, at each stage of production, the following parameters are controlled:

moisture; dressing
Network density, measured based on linear metrics.
Modulus of elasticity, estimated under tension:.
Twist; 0
saggy thread
After the manufacturing process is complete, the tensile strength is evaluated. In addition, elongation values at fiber breakage were determined
