Nylon thread—made of pure nylon multifilament, divided into long thread, short fiber line and elastic deformation line. The nylon thread is also called nylon thread.
The nylon thread is used to stitch a variety of clothing materials, with both practical and decorative functions. The quality of the nylon thread not only affects the sewing effect and processing cost, but also affects the appearance quality of the finished product. Therefore, the nylon thread is specially introduced to determine the general concept of nylon thread formation in a targeted manner.
The twist of the nylon thread means that the fiber structure of the thread is twisted to cause a relative angular displacement between the cross-sections of the wire, and the structure of the wire is changed by the inclination of the straight fiber and the axis. Twisting can make the thread have certain physical and mechanical properties such as strength, elasticity, elongation, gloss, feel, etc. It is expressed by the number of turns per unit length, and the number of turns per inch (TPI) or the number of turns per meter.
The twist of the nylon thread: 360 degrees around the axis is a roundabout. The twist direction of the nylon thread (S-direction or Z-direction): the oblique direction of the spiral formed by the rotation around the axis when the sliver is vertical. The oblique direction of the S direction coincides with the middle of the letter S, that is, the right hand direction or the clockwise direction. The direction of inclination of the Z direction coincides with the middle of the letter Z, that is, the left hand direction or the counterclockwise direction.
The relationship between the twist and the strength of the nylon thread: the twist of the nylon thread is proportional to the strength, but after a certain degree of twist, the strength decreases. If the degree is too large, the angle of the back is increased, the gloss of the line is poor, and the hand feel is poor; the degree of twist is too small, hairiness occurs, and the hand feels loose. This is because the increase in the twist and the increase in the frictional resistance between the fibers increase the strength of the wire. However, as the twist increases, the axial component of the sliver becomes smaller, and the stress distribution of the inner and outer fibers is uneven, resulting in inconsistency in fiber breakage.
In short, the fracture properties, strength and twist of the nylon thread are closely related. The twist and twist are determined according to the needs of the finished product and the post-processing, and are generally Z-direction.
