Problems solved by technology

At present, the polycarboxylic acid compounds used for anti-wrinkle finishing include 1,2,3,4-butanetetracarboxylic acid, citric acid, maleic acid, itaconic acid, polymaleic acid, etc., among which the most promising application development The most popular are 1,2,3,4-butane tetracarboxylic acid and citric acid, but the high cost of 1,2,3,4-butane tetracarboxylic acid is not suitable for large-scale application, and the fabric treated with citric acid is easy to pan yellow
As a polycarboxylic acid, malic acid has anti-wrinkle effect on treated fabrics, is not easy to yellow, has no formaldehyde release, and is cheap, but its strength loss is large, which seriously affects its wearing performance.

Embodiment 1

[0020] It is known that the original breaking strength of pure cotton cloth is 895 N and the wrinkle recovery angle is 89°.

[0021] Put the pure cotton cloth after scouring and bleaching into 2.0 wt% malic acid, 5.0 wt% sodium hypophosphite, 0.2 wt% triethanolamine stearate quaternary ammonium salt softener, 0.08 wt% penetrant JFC and the rest Immerse in a mixed solution of water, two dipping and two rolling to control the excess rate of 90%, drying at 100°C for 2 minutes, then baking at 180°C for 2 minutes, and finally soaping and drying. According to national standards GB / T 3923.2-2013 and GB / T 3819, the measured strength retention rate of cotton fabric is 55.0% and the wrinkle recovery angle is 176°.

Embodiment 2

[0023] It is known that the original breaking strength of pure cotton cloth is 895 N and the wrinkle recovery angle is 89°.

[0024] Put the pure cotton cloth after scouring and bleaching into 10.0 wt% malic acid, 5.0 wt% sodium hypophosphite, 0.2 wt% triethanolamine stearate quaternary ammonium salt softener, 0.08 wt% penetrant JFC and the rest of the water Dipping in the mixed solution, two dipping and two rolling to control the excess rate of 90%, drying at 100°C for 2 minutes, then baking at 180°C for 2 minutes, and finally soaping and drying. According to the national standards GB / T 3923.2-2013 and GB / T 3819, the measured strength retention rate of cotton fabric is 61.6% and the wrinkle recovery angle is 204°.

Embodiment 3

[0026] It is known that the original breaking strength of pure cotton cloth is 895 N and the wrinkle recovery angle is 89°.

[0027] Put the pure cotton cloth after scouring and bleaching into 8.0 wt% malic acid, 2.0 wt% sodium hypophosphite, 0.2 wt% triethanolamine stearate quaternary ammonium salt softener, 0.08 wt% penetrant JFC and the rest of the water Dipping in the mixed solution, two dipping and two rolling to control the excess rate of 90%, drying at 100°C for 2 minutes, then baking at 180°C for 2 minutes, and finally soaping and drying. According to the national standards GB / T 3923.2-2013 and GB / T 3819, the measured strength retention rate of cotton fabric is 68.0% and the wrinkle recovery angle is 164°.

Abstract

A method for non-formaldehyde anti-wrinkle finishing of cotton fabrics, which has the following steps: Step 1: put malic acid, sodium hypophosphite, triethanolamine stearate quaternary ammonium softener into the pure cotton cloth after scouring and bleaching, and penetrate Soaking in the mixed solution of JFC agent, two dipping and two rolling, control the excess rate of 90-100%; Step 2: drying, curing, soaping and drying. The invention has the following advantages: by using malic acid as anti-wrinkle finishing agent, adding sodium hypophosphite with catalytic effect, non-toxic softener and penetrating agent at the same time, it is used for anti-wrinkle finishing of cotton fabrics, while ensuring anti-wrinkle effect At the same time, it improves the previous problem of large loss of strength and wear resistance in anti-wrinkle finishing, and at the same time, the fabric has no yellowing phenomenon; the anti-wrinkle finishing agent is formed by a reasonable ratio of malic acid, catalyst, softener, and penetrating agent, which is green and environmentally friendly. It releases toxic and harmful substances such as formaldehyde, is safe and secure, and reduces production costs, so it has certain popularization and application value in production.

Description

technical field [0001] The invention relates to a method for wrinkle-resistant finishing of cotton fabrics, belonging to the technical field of dyeing and finishing. Background technique [0002] Pure cotton fabrics have the advantages of being comfortable to wear, breathable and moisture-absorbing, and soft to the touch. However, cotton fabrics have defects such as poor elasticity, easy deformation, easy wrinkling, and need to be ironed after washing. cannot maintain a flat appearance. Therefore, in order to improve the appearance of cotton fabrics during wearing, maintain their shape stability, and improve their wearability, it is very necessary to perform anti-wrinkle finishing on pure cotton fabrics. [0003] At present, the anti-wrinkle finishing agents commonly used in the anti-wrinkle finishing are still mainly urea-formaldehyde derivative resin finishing agents, that is, the structure contains N-methylol derivative structure, such as 2D or modified 2D resin. The fa...
