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 a polyester four-side elastic fabric with holes. The dyeing and finishing process specifically comprises the following steps: unwinding, pre-shrinking, cold stacking, desizing, grey cloth setting, in-cylinder desizing, in-cylinder dyeing, dewatering and scutching, shaping, reeling and packaging, and the pre-shrinking step comprises the following steps: using warm water for pre-wetting and then drying by drying cylinders, wherein the vehicle speed is 65-70 m / min, the pressure of a roller is 1.5-2.0 kg / cm<2>. According to the invention,the fabric is subjected to the pre-shrinking, so that the shrinking amplitude of the fabric is uniform, and the wrinkling abnormity caused by high-temperature sudden contraction is avoided; the fabric can be sufficiently shrunk at a certain temperature by the cold stacking, so that fibers are more tightly, bulk and plump, by the grey cloth setting, the grey cloth of the fabric is uniformly pre-shrunk at a high temperature, and shaped, meanwhile, the molecular structures of the fibers are rearranged so as to facilitate dyeing; the attractiveness of clothes in the wearing process can be kept bythe polyester four-side elastic fabric with the holes prepared by the process, the surface of the fabric is smooth, the holes are soft and natural, and the comfort is excellent.

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 fabric. 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. Due to its excellent elasticity, the fabric with four-sided elastic function can adapt to the activities of the human body. It is light and comfortable, and can also maintain the external beauty of the clothing. The knees and elbows of general clothing will be affected by the human body. Wearing or moving for a long time can not return to the original shape in a short time, and the fabrics in the above parts still maintain the shape of the knees and elbows and bulge, an...
