Problems solved by technology

The force between fiber molecules is mainly hydrogen bonds. After the molecules are subjected to external forces, the cellulose molecules slip and it is difficult to return to the original state, resulting in creases on the fabric surface, which greatly affects the wearability of the fabric.
At present, the wrinkle recovery angle of the resin-finished fabrics on the market is only 220-240° in the warp direction + weft direction. After repeated washing, there are still creases on the fabric surface, which affects the appearance of the clothes.

Embodiment 1

[0023] Fabric weave specification: CM50*CPT40*133*80*61 / 62, weave pattern: 1 / 1.

[0024] The finishing method to improve the wrinkle recovery angle of resin finishing is as follows:

[0025] (1) Conventional fabric pretreatment: the pure cotton gray fabric is sequentially singed, desized, scoured, bleached, mercerized, dyed or whitened to obtain a semi-finished fabric;

[0026] (2) Padding resin finishing solution:

[0027] The resin finishing liquid is composed of the following concentrations of components: high temperature resin CR-E: 150g / L, catalyst CT-C: 45g / L, fiber protection agent SF-P: 30g / L, polyvinyl alcohol: 4g / L, Citric acid: 1.5g / L, the rest is water;

[0028] The pure cotton fabric is pad-rolled with the above-mentioned working solution, and the excess rate of the fabric is 63%;

[0029] (3) The fabric after padding is sequentially pre-dried, needled, high-temperature baking reaction, washed, tentering, and pre-shrunk to obtain the finished fabric;

Abstract

The invention belongs to the technical field of textile finishing and processing, and particularly relates to a finishing method for improving the resin finishing wrinkle recovery angle. The finishingmethod for improving the resin finishing wrinkle recovery angle comprises the following steps of (1) pretreating a fabric; (2) padding with a resin finishing liquid; and (3) sequentially carrying outpre-drying, needling, high-temperature baking reaction, water washing, tentering and pre-shrinking on the padded fabric to obtain a finished fabric, wherein the resin finishing liquid is prepared from the following raw material components of 100 to 200g / L of high-temperature resin, 30 to 60g / L of catalyst, 20 to 40g / L of fiber protective agent, 2 to 6g / L of polyvinyl alcohol, 1 to 2g / L of citricacid and the reset of water. The process is simple, the wrinkle recovery performance of the fabric is further improved; the effect that no wrinkle exists on the washed fabric surface is achieved; thewearability and attractiveness of the fabric are improved; the quality is stable; and good popularization prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of textile finishing and processing, and in particular relates to a finishing method for improving the wrinkle recovery angle of resin finishing. Background technique [0002] Cellulose fabric products are easy to wrinkle after washing, which is caused by their poor wrinkle recovery. The force between fiber molecules is mainly hydrogen bonds. After the molecules are subjected to external forces, the cellulose molecules slip and it is difficult to return to the original state, resulting in creases on the fabric surface, which greatly affects the wearability of the fabric. At present, the crease recovery angle of the resin-finished fabrics on the market is only 220-240° in the warp direction + weft direction. After repeated washings, there are still creases on the fabric surface, which affects the appearance of the clothes. Contents of the invention [0003] In order to overcome the deficiencies in the prio...
