Problems solved by technology

However, due to the high water content of the printed fabric, directly entering the open-width machine will cause the printing and dyeing water to splash everywhere, which not only affects the working environment of the workshop, but also brings great changes to the later drying operation, and the drying time is extremely time-consuming. long and inefficient
And when drying, high temperature is often directly used to quickly dry the cloth, so that the cloth often becomes very hard and has poor softness

Abstract

A printing and dyeing process having a low decolourization ratio is disclosed. The process includes (1) a singeing step; (2) a dyeing step, namely a step of adding gray cloth into a dyeing pool and dyeing the gray cloth; (3) a squeeze drying step, namely a step of subjecting the dyed cloth to squeezing treatment by adopting a squeeze drying device, and then performing scotching treatment; and (4)a drying step, namely a step of subjecting the cloth to pre-baking treatment at 70-80 DEG C for 1-5 min before drying, the cooling the cloth to 40-60 DEG C, maintaining the temperature for 5-8 min, then raising the temperature to 120-150 DEG C, and baking the cloth for 3-8 min. The printed and dyed cloth is squeezed to remove water by the squeeze drying device so as to reduce the water content ofthe cloth before drying operation and to increase the drying efficiency, thus increasing the overall treatment efficiency. Pre-baking is performed before drying, and therefore the adhesion degree of dyeing liquid is increased, the cloth is not too hard and softness of the cloth is ensured.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a printing and dyeing process with low decolorization rate. Background technique [0002] Along with the raising of people's quality of life, people pay more and more attention to the attractive in appearance of clothing. In order to meet the production of fabrics of various colors and patterns, the fabric printing and dyeing process has emerged. The fabrics obtained after printing and dyeing have various colors and patterns, which can effectively improve the aesthetics of clothing or other cloth daily necessities or handicrafts. . [0003] After printing and dyeing, the cloth needs to be opened by the open-width machine to meet the later processing needs. However, due to the high water content of the printed fabric, directly entering the open-width machine will cause the printing and dyeing water to splash everywhere, which not only affects the working ...
