Problems solved by technology

Based on the existing finishing solution formula, by optimizing the sequence of treatment processes, compared with the traditional mercerizing process, the wrinkle recovery angle is increased by more than 30%, the strength is increased by more than 5%, and the hand feels softer and the drape is better. The technical scheme of cotton fabric has not been reported yet

Embodiment 1

[0030] A cotton fabric treatment process based on combined finishing of liquid ammonia and mercerizing: singeing → desizing → liquid ammonia → mercerizing → liquid ammonia → tenter → preshrinking;

[0031] The specific process of the desizing process is as follows: the fabric is immersed in the enzyme liquid → 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;

[0032] 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;

[0033] The specific process of the mercerizing process is as follows: the fabric is immersed in the lye (5min)→washed (with tension applied, 95°C)→neutralized and the pH value of t...

Abstract

The invention relates to the technical field of textile after-finishing, in particular to a cotton fabric treatment process based on liquid ammonia and mercerizing combined finishing. The cotton fabric treatment process based on liquid ammonia and mercerizing combined finishing comprises the following steps of singeing, desizing, liquid ammonia treatment, mercerizing, liquid ammonia treatment, tentering and preshrinking. The comprehensive physical and mechanical properties of the wrinkle recovery angle and the breaking strength of the cotton fabric are improved, and meanwhile, the hand feeling style of the cotton fabric is further improved. The cotton fabric treatment process based on liquid ammonia and mercerizing combined finishing is relatively simple and feasible, and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to the technical field of textile post-finishing, in particular to a cotton fabric treatment process based on combined finishing of liquid ammonia and mercerizing. Background technique [0002] Cotton fabric is a kind of soft and breathable fabric, but it is easy to wrinkle and deform, which affects its wearing performance. In view of these shortcomings of cotton fabrics, people usually use some treatments such as mercerizing and liquid ammonia to finish cotton fabrics in actual production. [0003] A separate mercerizing finish is usually used in the traditional process. In recent years, liquid ammonia treatment is more environmentally friendly than mercerizing, and liquid ammonia has been used instead of mercerizing in production. However, the fabrics finished by the single-pass liquid ammonia process and the single-pass mercerizing process cannot have the advantages of both, and there are still some deficiencies in performanc...
