Device and method for improving staining fastness of washing water of woven fabric

Abstract

The invention provides a device and method for improving the staining fastness of washing water of a woven fabric, and relates to the field of woven fabric dyeing. The method for improving the staining fastness of the washing water of the woven fabric comprises the following steps of performing dyeing, transporting the woven fabric into a box body 1, smoothing the front surface, smoothing the backsurface, and adding a wet friction enhancing agent. According to the device and the dyeing method for improving the staining fastness of the washing water of the woven fabric, one ends of two smoothing plates are hinged, and by means of the cooperation of a push rod and a telescopic rod, the two smoothing plates make opposite circular motion. The effect of smoothing the two sides of the woven fabric is achieved, and through the cooperation of motors, gears and a chain, the chain is enabled to drive smoothing hooks to move towards the edge of the woven fabric, and the smoothing hooks are enabled to smooth downwards turned wrinkles of the back surface of the woven fabric. Therefore, the problem that the staining fastness of the washing water at the wrinkles of the woven fabric in a water washing process is relatively poor because the wrinkles of the woven fabric cannot well contact with the wet friction enhancing agent due to the fact that the wrinkles are easily generated in a moving process of the woven fabric is avoided.

Description

technical field [0001] The invention relates to the technical field of woven fabric dyeing, in particular to a device and method for improving the color fastness of woven fabric to washing water. Background technique [0002] The process steps of the dyeing treatment of the woven fabric are: turning over, singeing, desizing, dyeing, adding a color fixing agent and a wet friction improving agent for treatment, washing, and drying. [0003] However, there are still some problems with the use of wet friction improving agents. For this reason, China Patent Network has disclosed "a processing method for improving the color fastness to wet rubbing of cellulose fiber textile fabrics", the patent number is 201910331113.2. The above-mentioned device is provided with a U-shaped spray pipe, so that the nozzle holes on both sides of the U-shaped spray pipe are arranged in a staggered manner, so that the wet friction improving agent can be evenly sprayed on the cloth surface.

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a device and a method for improving the color fastness of weaving to washing water, which solves the problem that the weaving washing device generally used in the above-mentioned background technology has a problem in the moving process of weaving. Wrinkles are prone to occur, resulting in poor contact with the wet friction enhancer at the folds of the fabric, which in turn causes poor color fastness to washing water at the folds of the fabric during washing
