Environmentally-friendly printing and dyeing technology for high-efficiency singeing

Abstract

The invention discloses an environmentally-friendly printing and dyeing technology for high-efficiency singeing. The environmentally-friendly printing and dyeing technology for high-efficiency singeing comprises the following steps: (1) cloth is placed onto a conveyer belt and conveyed to a singeing machine through the conveyer belt; and the singeing machine combusts fluff of the cloth through anannular electrothermic metal tube, and the cloth is fixed through a negative pressure suction device; (2) the cloth which has undergone singeing is conveyed through the conveyer belt to a desizing machine, and the desizing machine carries out desizing treatment on the cloth; (3) the cloth which has undergone desizing treatment is conveyed through the conveyer belt to a scouring machine, and the scouring machine carries out high-temperature scouring on the cloth; (4) the cloth which has undergone scouring then undergoes impurity removal treatment by an impurity removal device on the scouring machine; (5) the cloth which has undergone impurity removal undergoes washing operation in a washing trough; and (6) the washed cloth is conveyed through the conveyer belt to a dyeing machine, and the dyeing machine carries out dyeing treatment on the cloth. In comparison with the prior art, the invention has the following beneficial effects: the singeing effect is greatly improved, and technology has characteristics of high printing and dyeing efficiency and low labor.

Description

technical field [0001] The invention relates to the field of cloth printing and dyeing, in particular to an environmentally friendly and highly efficient singeing printing and dyeing process. Background technique [0002] At present, the cloth printing and dyeing industry is developing more and more rapidly, and the competition is becoming more and more fierce. The printing and dyeing process of the cloth determines the quality of the finished cloth. Therefore, the printing and dyeing process of the cloth plays a pivotal role in the field of cloth production. The traditional fabric printing and dyeing process generally includes singeing, desizing, scouring, and printing and dyeing processes, while the traditional singeing process is to quickly pass the fabric through a high-temperature flame, or rub the hot metal surface to make the fluff on the cloth surface Rapidly heats up and burns to effectively remove fluff from the surface of the cloth. Then the fabric after the sing...

AI Technical Summary

Problems solved by technology

However, in the traditional singeing process, the contact area between the cloth and the flame or the metal surface is small, so that the area where the fluff is burnt after the cloth passes through the flame once is also small, and it needs to be singed many times, which is inefficient

In traditional desizing, the fabric is immersed in water for repeated cleaning, which is inconvenient to operate and low in desizing efficiency

In traditional scouring, it is usually necessary to manually clean the fabric after scouring, which is labor-intensive and inefficient.

In the dyeing process, the dye in the traditional dyeing box will precipitate due to the gravity of the dye after a period of use, and it needs to be stirred again to mix the dye with the aqueous solution. Cloth, the cloth needs to be taken out, so that the whole dyeing process stops, thus greatly reducing the dyeing efficiency
