Polyester printed fabric thickened hand feeling process

Abstract

The invention relates to the technical field of fabric processing, in particular to a polyester printed fabric thickened hand feeling process. The process comprises gray fabric treatment, printing drying, combed surface water washing and drying and desizing and setting, and a stretcher adopted comprises pull cylinders, a rack and a controller. Due to the fact that fine wrinkles generated in a winding process after the winding-packaged gray fabric is re-stretched can be embodied on the pull cylinders, an actual length of the gray fabric between the pull cylinders is changed, a constant stretchrate state of the pull cylinder on the gray fabric is broken, and then the embodiment of thick hand feeling in subsequent gray fabric processing is weakened therefore, by arranging a sensor arranged on each pull cylinder and an independent drive servo motor matching the end part of each pull cylinder, the stretch rate change of the gray fabric between the pull cylinders is fed back to the controller, a rotation operation state between the pull cylinders is adjusted in time, the stable stretching effect on the gray fabric is maintained, so that the application effect of the polyester printed fabric thickened hand feeling process is improved.

Description

technical field [0001] The invention relates to the technical field of fabric processing, in particular to a technique for thickening the handle of polyester printed fabrics. Background technique [0002] Polyester is a common name for polyester fiber. It is a synthetic fiber obtained by spinning polyester, which is a polymer compound. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength. It is a kind of chemical fiber clothing fabric that is widely used in daily life. As a clothing fabric, its surface is often processed with pattern lines to highlight the differences between fabrics and the personality of the wearer. At the same time, printing on polyester fabrics During the process, the handle properties of the polyester fabric itself have also been changed; for the introduction of the handle of polyester printed fabrics, please refer to: Miao Huali et al., Quantitative characterization of the handle sty...

Problems solved by technology

[0003] After the gray cloth wrapped and packaged is re-stretched, the fine wrinkles generated during the winding process will be reflected on the drawing cylinder, which changes the actual length of the gray cloth between the drawing cylinders, and destroys the constant pulling of the gray fabric by the drawing cylinder. The state of elongation weakens the printing effect in subsequent gray fabric processing, and the damage to its fiber structure will affect the thick feel of the final fabric

[0004] In the prior art, there are also some technical solutions about the thickening process of polyester printed fabrics. For example, a Chinese patent with application number 2019108608130 discloses a dye discharge auxiliary agent for polyester fabrics, which includes the following components in weight percentage: Divide: deionized water 50-73%; phosphoric acid: 1-5%; reducing agent: 15-25%; emulsifier: 1-5%; thickener: 10-15%; printing paste for polyester fabrics, including the above Discharge auxiliary agent 94-100%, P-type disperse dye: 0-6%; a discharge printing method for polyester fabric is also provided, including the following steps: printing paste printing: printing paste on the surface of the dyed polyester fabric Printing to form a pattern with color; steaming: the reducing agent restores the original disperse dyes that have been dyed on the surface of the polyester fabric; cleaning the residual printing paste; the process is simple, energy saving and consumption reduction; Well, the printing paste using the discharge dyeing auxiliaries can realize the printing of polyester fabrics after high-temperature dyeing, which saves energy and time; the polyester fabrics obtained after high-temperature dyeing and printing have excellent fastness, uniform color discharge printing, and softness. and plump feel; but this technical solution does not solve the internal stress of the fabric in the polyester gray cloth before printing, and after the polyester fabric is printed and finalized, the fabric is processed to form a light and thin handle of flexible fibers.
