Abstract

The invention relates to a dyeing and finishing processing method for a fabric, in particular to a dyeing and finishing processing method for a T / R spandex elastic fabric. A production technique comprises the following steps: preparing a fabric; pretreating by a jig dyeing machine; rinsing and drying; carrying out high-temperature and high-pressure boiling off by an overflow dyeing machine; presetting; singeing; dyeing; drying; carrying out assistant setting; decatizing; rinsing and shaping; inspecting, rolling and packaging. The T / R spandex fabric produced by adopting the production techniquedisclosed by the invention has the following characteristics of soft hand feeling, good elasticity, fluffy fabric and good stability of fabric size; the problem of shrinkage of the T / R spandex fabricis effectively avoided, the cloth cover is smoother and cleaner, and the problems of thermal shrinkage and high washing shrinkage of the fabric are greatly improved.

Description

technical field [0001] The invention relates to a dyeing and finishing method for fabrics, in particular to a dyeing and finishing method for T / R spandex four-way stretch fabrics. Background technique [0002] With the continuous improvement of living standards, people have more and more functional requirements for clothing fabrics. For the traditional winter clothing that only has the function of keeping warm, its bloated, cumbersome and lack of novelty style has been difficult to meet the consumption concept of consumers, and the public is more eager for the emergence of novel and dynamic new fabrics. Nowadays, elastic fabrics containing spandex are very popular in domestic and foreign markets. These products have high shrinkage and excellent resilience, soft to the touch, comfortable to wear and can show the beauty of the body. In addition, they are easy to absorb sweat and will not produce Due to static electricity and other reasons, it has always had a great advantage ...
