Problems solved by technology

[0004] However, during the stretching process of the fabric, due to factors such as the stretching force and the quality of the fabric itself, the properties of the fabric are easily damaged during the stretching process. It affects the performance of the fabric produced in the later stage, and increases the cost of textile technology and materials

Embodiment

[0040] see figure 1 and figure 2 , a textile fabric stretching process, comprising the following steps:

[0041] S1. Evenly apply the base color paint mixed with radial pins on the surface of the fabric to be processed, and form a color coating layer after drying. The base color paint is washable paint;

[0042] S2. Heating the fabric with the color covering layer, the radial needle piece is partially melted by heating, and changes from a fixed state to a crackable state;

[0043] S3. Pull the opposite ends of the fabric to both sides, that is, perform a uniaxial stretching operation on the fabric, and at the same time, the color-covered layer will disperse as the fabric stretches;

[0044] S4. When the fabric is stretched unevenly, the color-coated layer at the over-stretched part will be over-dispersed, causing the radial needle sheet to crack, and the color-developing liquid inside it will overflow, and the part will be marked;

[0045] S5. After the stretching is complet...

Abstract

The invention discloses a textile fabric stretching auxiliary part and a stretching process, belonging to the field of fabric processing technology. The base color paint introduced with radial pins is coated on the surface of the unstretched fabric to form a color coating layer, and It is heated to destroy the structure of the radial needles and make it crackable. During the stretching process of the fabric, the color coating layer migrates and disperses with the fabric, triggering the cracking of the radial needles inside it, realizing the The over-stretched parts are subjected to a double-channel color marking process in sequence. According to the color marking area on the surface of the color covering layer, the overall performance distribution of the fabric can be obtained, so as to facilitate the basic quality evaluation and rational use of the stretched fabric. Effectively reduce the waste of textile materials and process costs.

Description

technical field [0001] The invention relates to the field of fabric processing technology, in particular to a textile fabric stretching aid and a stretching process. Background technique [0002] It is a method to make the polymer chains in the polymer align along the direction of the external force, so as to improve the structure and mechanical properties of the polymer. Stretching can be divided into uniaxial stretching and biaxial stretching. The former aligns the chains along one direction, while the latter aligns the chains along a plane. [0003] Uniaxial stretching is an important means to improve the strength of chemical fibers. Usually, the ratio of the length of the fiber before and after stretching is used to define the draw ratio of the fiber. As the draw ratio increases, both the modulus and strength of the fibers increase. In the spinning process, it is hoped to generate as many extended chain structures as possible to obtain high-strength, high-modulus synt...
