Problems solved by technology

It is specifically manifested in the partial crosslinking reaction between the cotton fabric and the resin during storage and transportation, resulting in wrinkles that are difficult to remove, and at the same time causing problems such as a decrease in the whiteness of delayed baking sensitized fabrics.
[0003] In the prior art, people mostly improve the storage stability of delayed-baking sensitized fabrics by designing and optimizing resin finishing agents and catalytic systems, and there are no reports on the literature that achieves the aforementioned improvement effects by optimizing the finishing process

Embodiment 1

[0035] Example 1 (delayed curing sensitized fabric, process does not contain storage→curing step)

[0036] A cotton fabric delayed baking non-ironing finishing process includes a pretreatment process and a posttreatment process.

[0037] Pretreatment process: singeing → desizing → liquid ammonia → mercerizing → liquid ammonia;

[0038] The specific process of the desizing process is as follows: the fabric is immersed in the enzyme solution → steamed (stacked at 100°C for 20 minutes) → washed with water (95°C) → dried. Conditions: desizing enzyme 3g / L; penetrant 4g / L; chelating agent 2g / L; vehicle speed 70m / min;

[0039] The specific flow of the liquid ammonia process is: cloth feeding→pre-drying→cooling→liquid ammonia treatment (dipping liquid ammonia for 15s→drying)→steaming (95°C)→water washing (95°C)→drying→cloth falling. Conditions: vehicle speed 60m / min; temperature of treatment chamber 80°C; pH value of falling cloth 6;

[0040] The specific process of the mercerizing...

Embodiment 2

[0064] Embodiment 2 (delay baking fabric, technique contains storage→baking step)

[0065] A cotton fabric delayed baking non-ironing finishing process includes a pretreatment process and a posttreatment process.

[0066] Pretreatment process: singeing → desizing → liquid ammonia → mercerizing → liquid ammonia;

[0067] The specific process of the desizing process is as follows: the fabric is immersed in the enzyme solution → steamed (stacked at 100°C for 20 minutes) → washed with water (95°C) → dried. Conditions: desizing enzyme 3g / L; penetrant 4g / L; chelating agent 2g / L; vehicle speed 70m / min;

[0068] The specific flow of the liquid ammonia process is: cloth feeding→pre-drying→cooling→liquid ammonia treatment (dipping liquid ammonia for 15s→drying)→steaming (95°C)→water washing (95°C)→drying→cloth falling. Conditions: vehicle speed 60m / min; temperature of treatment chamber 80°C; pH value of falling cloth 6;

[0069] The specific process of the mercerizing process is as f...

Embodiment 3

[0072] A delay-baking and non-ironing finishing process of cotton fabrics refers to Example 2. The difference between Example 3 and Example 2 is that the 3 minutes of baking in the post-baking finishing process B is adjusted to 6 minutes of baking.

Abstract

The invention relates to the technical field of textile after-finishing, in particular to a cotton fabric delayed baking non-ironing finishing process. The cotton fabric delayed baking non-ironing finishing process comprises the following steps of singeing, desizing, liquid ammonia treatment, mercerizing, liquid ammonia treatment and after-baking finishing. According to the method, the stability of the delayed baking sensitized fabric in delayed baking is remarkably improved, the problem caused by slow reaction in the storage process of the delayed baking sensitized fabric is solved, and the product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of textile post-finishing, in particular to a delayed-baking and non-ironing finishing process for cotton fabrics. Background technique [0002] As a soft and breathable fabric, cotton fabric has the problem of easy wrinkling and deformation. Aiming at these shortcomings of cotton fabrics, the more effective technological methods are to carry out non-ironing finishing and liquid ammonia finishing on them. Pre-baking non-ironing, wet non-ironing, post-baking non-ironing, garment non-ironing, etc. are representative finishing methods in non-ironing finishing. Among them, the delayed baking method is a non-ironing finishing process that is beneficial to obtain a better setting effect for garments, but the low stability of the delayed baking sensitized fabrics produced by this process has always been a key issue in the process development. It is specifically manifested in the partial cross-linking reaction bet...
