Problems solved by technology

However, due to the high water content of the printed fabric, it takes a long time to dry and the work efficiency is low.
And before the cloth is dyed, there are often large impurities or acidic substances on the cloth, which easily affects the coloring rate during dyeing.

Abstract

The invention discloses a printing and dyeing process capable of efficiently saving energy. The process includes the steps of singeing; dyeing, wherein grey cloth is put into a dyeing pond for dyeingtreatment; extrusion for dewatering, wherein the dyed cloth is subjected to dewatering treatment through an extrusion device for dewatering, and scutching treatment is conducted on the cloth after dewatering; drying, wherein cloth is subjected to pre-roasting treatment at 70-80 DEG C for 1-5 minutes before drying, then the cloth is cooled to 40-60 DEG C, the temperature of the cloth is maintainedfor 5-8 minutes, and finally the temperature is raised to 120-150 DEG C to conduct roasting on the cloth for 3-8 minutes. By using the extrusion device for dewatering to conduct extrusion on the dyedcloth for dewatering, the water content of the cloth before drying is reduced, the drying efficiency is increased, and therefore the overall processing efficiency is increased; moreover, by carrying out pre-roasting before drying, the adhesiveness of a dyeing liquid can be improved, the cloth is not hardened easily, and the 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 an energy-saving and high-efficiency printing and dyeing process. 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, it takes a long time to dry and the work efficiency is low. And before the cloth is dyed, there are often large impurities or acidic...
