What is the twist silk?

What is the twist silk?What is the effect of twisting?Twisted silk is also known as double twist silk, twist silk, is a single silk or femoral thread twist, so that to obtain a certain twist and twist back number of technology, similar to rubbing rope.
Function of twist wire:
(1) Increase the strength and friction resistance of the wire to reduce hair and dead head and improve the fastness of the silk fabric.
(2) makes the silk wire have a certain shape and color, giving the fabric appearance with refractive, crepe or wool ring, knot son and other effects.
(3) adds the elasticity of wire, improves wrinkle resistance (imitation memory heat-free fabric) and breathability (strong twist fabric), and makes the fabric cool and comfortable to wear.
The following problems should be paid attention to in the twist wire in production:
(1) twist method has two kinds of dry twist and wet twist. Routine twist is dry twist, but for some multiple mulberry silk, wet twist method must be used to meet the process requirements.
(2) dry twist processing uses ordinary twist machine and double twist machine, while wet twist twist machine.
(3) to make the yarn surface has hair feather, knot son and other fancy effect, must use fancy twist machine.
(4) yarn has a twist against the initial twist.
(5) Whether the warp and longitude silk raw materials need to twist, why twist, add what twist, add how much twist, should be set according to the requirements of the fabric variety specifications.In addition to fancy twist machine, other twist processes require good winding formation, easy to disassembly, uniform tension, appropriate size, uniform twist, and steam shaping is not roll.Increase the winding appropriately to improve the yield and quality of twist wire processing.
