Embodiment Construction

[0011] The present invention is described in detail below.

[0012] The present invention is the production method of yarn, promptly is the method that becomes yarn from fiber processing, and requires to make its product by the method of the present invention, namely yarn has certain elasticity, usually requires that its elasticity ratio can reach the 1-1 of the original length of product. It is about 4 times higher, and it has a strong three-dimensional effect and a fluffy and soft feel.

[0013] The production method of circular elastic yarn referred to in the present invention, comprises the steps:

[0014] Step A: Perform compound twisting on more than one fiber, that is, use relevant processing machinery to perform compound twisting on the fibers. The compound twisting is divided into two steps: pre-twisting and post-twisting. The technical parameters involved are The twist of the front twist is 300-500 twist / m, and the twist of the back twist is 100-260 twist / m. The a...

Abstract

The invention relates to a production method of circular stretch yarn. According to the production method, more than one fiber is subjected to combined twisting, wherein the combined twisting includes two steps of forward twisting and backward twisting, the forward twisting degree is 1300-500twists / m, the backward twisting degree is 100-260twists / m, the twisting is conducted in an S direction or a Z direction, then the reverse added twisting is conducted in the S direction or the Z direction, the twisting degree is 1200-1500twists / m, and the like. By using the production method, the elastic yarn with the appearance shaped like a continuous clockwise or anti-clockwise paparalle circles is obtained without the processing of an elasticity improving device and the addition of elastic materials, the elastic rabbi is about one to four times of the length of original shape of the stretch yarn, the finished stretch yarn has strong gradation and three-dimensional effect, the surface of the stretch yarn is soft, and the production method can be widely applied to various fabrics.

Description

technical field [0001] The present invention relates to the production method of the yarn used in weaving cloth, weaving lace or ribbon, etc., specifically, it is a method that can produce a yarn with an elastic Ratio of about 1-4 times without adding any elastic raw materials and without using any elasticizing equipment. elastic yarn. Background technique [0002] In the prior art, if you want to produce elastic yarn with a certain elasticity, there are usually only two methods. One method is to use texturing equipment to process the yarn; the other method is to add spandex, Elastic and other elastic fibers. All are difficult to produce the yarn with certain elasticity by these traditional methods. Moreover, its appearance is straight, unable to achieve the shape of parallel circles, and there are defects such as poor three-dimensional effect and insufficient softness. Contents of the invention [0003] In the prior art, if you want to produce elastic yarn with a certa...
