Problems solved by technology

[0004] However, because the production process is relatively complicated and the production process is difficult to control, every detail in the production process must be rigorous to ensure that the function of the product can achieve the best effect, so the risk is relatively high, and its production cost is high. It is of great value and significance to study the production process of the four-sided elastic functional fabric with holes

Abstract

The invention relates to a dyeing and finishing process for polyester hole-hole four-sided elastic fabric, which specifically comprises the following steps: unwinding, pre-shrinking, cold stacking, desizing, blank setting, in-cylinder desizing, in-cylinder dyeing, dehydration and opening, shaping, Rewinding packaging, in which the pre-shrinking step is pre-wetted with warm water and then placed on the drying cylinder, the speed is 65-70m / min, and the roller pressure is 1.5-2.0kg / cm 2 , and control the temperature of each drying cylinder. In the invention, the shrinkage of the fabric is made uniform by pre-shrinking and the abnormal wrinkling caused by high temperature sudden shrinkage is avoided. While uniformly shrinking and shaping, the molecular structure of the fiber is rearranged to facilitate dyeing. The polyester hole four-way elastic fabric prepared by the process of the present invention can maintain the beauty of the clothes during the wearing process, the surface of the fabric is flat, and the holes Soft and natural, with great comfort.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a dyeing and finishing process of polyester hole four-sided stretch cloth. Background technique [0002] With the continuous improvement of people's living conditions, people have higher and higher requirements for the functional selection of clothing fabrics. In addition to the normal warmth retention and wearing comfort of the fabrics, other more properties of the fabrics will also be considered. The fabric with four-sided elastic function can adapt to the activities of the human body due to its excellent elasticity, stretches and shrinks, is light and comfortable, and can also maintain the external appearance of the clothing. Generally, the knees and elbows of the clothes will be affected by the body. Long-term wearing or activities cannot return to its original shape in a short time, and the fabrics in the above parts still maintain the shape of the knees ...
