Steam box used for scouring and bleaching equipment, scouring and bleaching equipment and steaming method

Abstract

The invention discloses a steam box used for scouring and bleaching equipment, scouring and bleaching equipment and a steaming method. The steam box comprises a preheating zone, a first temperature zone and a second temperature zone; a steam box guide roller used for transmitting fabrics is arranged in the preheating zone; a first crawler belt set and a second crawler belt set are respectively arranged in the first temperature zone and the second temperature zone; the transmission directions of adjacent crawler belts in the first crawler belt set and the second crawler belt set are opposite; the crawler belts are staggered in parallel to form the continuous transmission of the fabrics, thereby enabling the fabrics to be stacked on the crawler belts and continuously transmitted; the steam box is arranged in the scouring and bleaching equipment and treats the fabrics according to certain process flows. The invention thoroughly solves the problems that the scouring and bleaching effect is not ideal, the cloth cover evenness of the fabrics is poorer, the dimensional stability is poor because the textile stretch rate is overlarge, the effects of energy saving and consumption reducing are not ideal and the like, thereby continuously producing the fabrics with high evenness, high whiteness and high capillary effect but without creases.

Description

technical field [0001] The invention relates to a one-bath one-step-stage pre-steaming equipment and method for cotton knitted fabrics in the printing and dyeing industry, in particular to a steam box used for scouring and bleaching equipment, scouring and bleaching equipment and a steaming method. Background technique [0002] The cuticle and primary cell wall of various cotton fibers contain 0.4-1.2% pectin, 0.4-1.2% lipid wax, 1.0-1.9% protein, 0.7-1.6% ash and other natural impurities or companions, the above The existence of impurities or accompanying organisms directly affects the wettability of cotton fibers, making cotton fibers hydrophobic, which in turn affects the properties of cotton fibers such as dyeing and finishing. Therefore, cotton textile products need a pretreatment process before dyeing and finishing to remove natural impurities or accompanying organisms on cotton fibers, improve the wetting and permeability of cotton fabrics, and create good conditions ...

AI Technical Summary

Problems solved by technology

However, the flatness of the treated fabric is poor, the fabric surface will produce more wrinkles, the fabric is stretched to a greater extent, and the fabric shrinkage rate is relatively large. More importantly, it is difficult to realize the one-step process of scouring and bleaching.

[0007] The third open-width processing method for tubular fabrics: the advantage of this processing method is that the tubular fabric does not need to be cut before scouring and bleaching, and it does not need to be dried and overlocked after scouring, bleaching and before dyeing, and the processing process is less. , low cost, and good fabric flatness, but it is easy to appear "edge mark" phenomenon, and at the same time, it is difficult to protect the fiber strength, it is not easy to realize the one-step process of scouring and bleaching, and it has the highest requirements for process technology and processing equipment
