Crease prevention device for scouring and bleaching equipment, scouring and bleaching equipment and crease prevention method

Abstract

The invention discloses a crease prevention device for scouring and bleaching equipment, scouring and bleaching equipment and a crease prevention method; a fabric is led in a fabric soaking vessel by a fabric lead-in roller; the fabric enters in hot water of the fabric soaking vessel and hot water flows through the fabric continuously under the condition that the fabric is in a loose state; the fabric in the fabric soaking vessel is led out to the next procedure by a fabric lead-out roller; the crease prevention device is arranged in the scouring and bleaching equipment, and the fabric is processed according to the process flows; in the invention, the fabric is fully self-swelled in the crease prevention device, the crease ratio of cotton knitted textile is reduced, the flatness of the cotton knitted textile is kept; in addition, the crease prevention device and a steam box in the scouring and bleaching equipment are improved, the fabric passes through a fabric trolley, an immersion device, the steam box and a rinsing machine sequentially by a delivery mechanism, so as to realize continuous processing and greatly improve the processing efficiency; under the condition of low cost operation, the fabric with no crease, high planeness, high whiteness and high capillary effect can be processed continuously.

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 an anti-folding device for scouring and bleaching equipment, scouring and bleaching equipment and an anti-folding 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 ...

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
