Sorting method for improving gloss and flatness after all-cotton fabric is washed

Abstract

The invention provides a sorting method for improving gloss and flatness after all-cotton fabric is washed. Singeing, preprocessing, pre-tentering, mercerizing, whitening tentering, printing or dyeing, washing, pre-sorting, high-temperature washing, soft sizing, calendaring and preshrinking are conducted on grey cloth, and then the fabric is obtained. According to the sorting method, a moist-crosslinking technology is not needed so that a better washable effect can be achieved, the fabric cover is good in gloss and flatness after the obtained fabric is washed, the gloss is bright after multiple times of washing is conducted, a lifting effect is achieved on the shrinkage rate, and formaldehyde testing conforms to the national detecting standard.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a finishing method for improving the gloss and flatness of cotton fabrics after washing. Background technique [0002] Cotton bedding fabrics have problems of poor luster, poor surface smoothness and poor color saturation after washing. In order to improve the defects of wrinkling and poor luster of cotton fabrics during use and washing, non-iron finishing will be carried out on all cotton fabrics. At present, the traditional non-ironing finishing process is to use padding resin finishing agent after the double mercerizing process The wet cross-linking process of storage reaction is carried out again, but the wet cross-linking process has problems such as strong damage, unsustainable effect, and substandard safety indicators (such as formaldehyde content, etc.). [0003] Patent 02135285.2 discloses a non-ironing finishing method for pure cotton fa...

Problems solved by technology

For most of the current printing and dyeing processing conditions, the constant temperature room is one of the main factors restricting the application of the process, and storage for 16-24 hours will also cause low production efficiency to a certain extent, which is not conducive to large-scale production applications

[0004] Patent CN102828393 discloses a non-iron finishing method for pure cotton or polyester-cotton fabrics. It adopts a foam finishing process, which greatly reduces the waste of materials and saves energy. However, using a foam machine to directly apply foam to the tenter frame will easily cause unevenness. And the problem of permeability, it is contrary to the principle of foam finishing to achieve better finishing and processing effect without using physical pressure such as padding, and the performance requirements of foam finishing agents such as high stability and permeability , the same wet cross-linking process is not conducive to large-scale production
