High whiteness textile non-ironing finishing method and textile

Abstract

The invention relates to a non-iron finishing method and a textile fabric with high whiteness. The non-iron finishing method for textiles includes sequentially performing pretreatment, mercerizing, cold stacking, moisture crosslinking and post-processing on textile raw materials; wherein, the cold stacking process includes the steps of: treating the textile material with a treatment liquid. After the mercerization process, the textiles are treated, then stacked and dried; the treatment solution contains derivatives of stilbene disulfonic acid and derivatives of stilbene tetrasulfonic acid; the moisture cross-linking process includes the following steps : The wet crosslinking finishing liquid is used to carry out moisture crosslinking treatment on the textile fabrics after the cold stacking process, and then stacking; the moisture crosslinking finishing liquid contains derivatives of stilbene disulfonic acid. The whiteness CIE value of the textile fabric prepared by the finishing method can reach more than 160 degrees, and the color is pure and bright, and meanwhile, the non-ironing effect is good, and the washing resistance is good.

Description

technical field

[0001] The invention relates to the technical field of finishing textiles, in particular to a high-whiteness non-ironing finishing method for textiles and textiles. Background technique

[0002] With the improvement of people's quality of life, the requirements for clothing are getting higher and higher, especially white clothing, high-quality textiles with high whiteness, translucence, and non-ironing can become high-grade fabrics, bringing better economic benefits .

[0003] In the traditional method, the whiteness of the non-ironing finished fabric is low, and the fabric does not look pure white and translucent. Some methods use fluorescent whitening agents for finishing, but the whiteness is not significantly improved, and the whiteness CIE value that can be obtained is usually less than 150 degrees. Contents of the invention

[0004] Based on this, it is necessary to provide a high-whiteness non-ironing finishing method for textiles. The whiteness C...

Examples

Embodiment 1

[0031] This embodiment is a high-whiteness non-ironing finishing method for textiles. The textiles to be finished are pure cotton white woven fabrics, and the single yarn count is 50S. The non-ironing finishing steps are as follows:

[0032] (1) Pre-treatment: Singeing and desizing the textiles to be finished according to conventional methods;

[0033] (2) High-alkali concentrated mercerizing: use a sodium hydroxide aqueous solution with a concentration of 24 mg to carry out mercerizing, and the processing time is about 60s;

[0034] (3) Liquid ammonia mercerizing: use Koyto liquid ammonia mercerizing machine, the speed is 60 m / min, and the corresponding soaking time in liquid ammonia is about 20s;

[0035] (4) Cold stacking and whitening: dipping the textiles after liquid ammonia mercerizing with the treatment liquid, then stacking for 15 hours, and drying with a setting machine; the treatment liquid is fluorescent whitening agent BMU (stilbene two Derivatives of sulfonic ac...

Embodiment 2

[0039] In this embodiment, a high-whiteness non-ironing finishing method for textiles, the textiles to be finished and the steps are the same as in Example 1, the difference is that:

[0040] In step (4), the time of stacking is 22 hours.

Embodiment 3

[0042] In this embodiment, a high-whiteness non-ironing finishing method for textiles, the textiles to be finished and the steps are the same as in Example 1, the difference is that:

[0043] In step (5), the moisture content of the textile after the moisture crosslinking treatment is controlled to 6-8%, and the stacking time is 25 hours.
