Description

Environment-friendly and efficient singeing printing and dyeing process

Technical Field

The invention relates to the field of cloth printing and dyeing, in particular to an environment-friendly and efficient singeing printing and dyeing process.

Background

At present, the development of the fabric printing and dyeing industry is faster and faster, the competition is more and more intense, and the quality of a finished fabric product is determined by the printing and dyeing processing technology of the fabric, so that the printing and dyeing technology of the fabric plays a significant role in the field of fabric production. The traditional printing and dyeing process of the cloth generally comprises singeing, desizing, scouring, printing and dyeing and the like, and the traditional singeing process is that the fabric rapidly passes through high-temperature flame in a flat width mode or rubs over a hot metal surface to enable fluff on the surface of the cloth to be rapidly heated and burnt, so that the fluff on the surface of the cloth is effectively removed. And then, the cloth after the singeing process is sent to the next desizing process, wherein the desizing process is mainly to coat sizing agents before the warp is woven so as to improve the strength and the wear resistance of the warp, but the sizing agents increase the consumption of dyeing chemicals during printing and dyeing, so that the desizing operation is required. And (3) after desizing, performing a scouring process, further removing incompletely removed sizing agent and most of natural impurities, washing with water, removing the impurities from the cloth, and finally dyeing to finish the printing and dyeing operation of the cloth. However, in the conventional singeing process, the contact area between the fabric and the flame or the metal surface is small, so that the area of the fabric burnt by the fluff after the flame once is also small, and the singeing needs to be performed for many times, which is low in efficiency. When traditional desizing immerse the cloth in aqueous and rinse repeatedly, the operation is inconvenient and desizing inefficiency. During traditional scouring, the cloth is generally cleaned manually after the scouring of the cloth is finished, so that the labor intensity is high and the efficiency is low. And when carrying out dyeing process, the dyestuff in traditional dyeing case can take place to precipitate because the gravity reason of dyestuff after a period of use, need stir again, let dyestuff and aqueous solution mix, and in order not to destroy the cloth during the stirring, need take out the cloth for whole dyeing process stops, thereby greatly reduced dyeing efficiency.

In view of the above, the applicant has made an intensive study to solve the above problems and has made the present invention.
