Embodiment 1

[0042] Add 11 parts by weight of ethanol to 100 parts by weight of water, add cotton fabric (the mass ratio of cotton fabric to water is 1:6), and stir at 50° C. for 20 minutes. 13 parts by weight of acrylic acid was added, followed by stirring at 50° C. for 30 minutes. Next, under ultrasonic stirring, 3 parts by weight of glyoxal, 3 parts by weight of maleic acid salt and 3 parts by weight of ammonium persulfate were sequentially added, the temperature was raised to 90° C., and the reaction was kept for 60 minutes. Then the above-mentioned treated cotton fabric is taken out, washed with water, and dried in the air, so as to obtain the non-ironing cotton fabric A1.

Embodiment 2

[0044] Add 10 parts by weight of ethanol to 100 parts by weight of water, add cotton fabric (the mass ratio of cotton fabric to water is 1:5), and stir at 40° C. for 30 minutes. 10 parts by weight of acrylic acid was added, followed by stirring at 40° C. for 60 minutes. Next, under ultrasonic stirring, 5 parts by weight of glyoxal, 2 parts by weight of fumarate and 4 parts by weight of ammonium persulfate were sequentially added, the temperature was raised to 80° C., and the reaction was maintained for 90 minutes. Then the above-mentioned treated cotton fabric was taken out, washed with water, and dried to obtain the non-ironing cotton fabric A2.

Embodiment 3

[0046] Add 12 parts by weight of ethanol to 100 parts by weight of water, add cotton fabric (the mass ratio of cotton fabric to water is 1:7), and stir at 60° C. for 10 minutes. 15 parts by weight of acrylic acid was added, followed by stirring at 60° C. for 30 minutes. Next, under ultrasonic stirring, 4 parts by weight of glyoxal, 4 parts by weight of itaconate and 2 parts by weight of ammonium persulfate were sequentially added, the temperature was raised to 100° C., and the reaction was kept for 30 minutes. Then the above-mentioned treated cotton fabric is taken out, washed with water, and dried in the air, thereby obtaining the non-ironing cotton fabric A3.

Abstract

The invention relates to the technical field of textiles, and discloses a method for in-situ non-ironing finishing of cotton fabrics with acrylic acid and glyoxal. The method comprises the following steps: (1) adding ethanol to water, adding cotton fabric, stirring at 40-60°C for 10-30 minutes; (2) adding acrylic acid, stirring at 40-60°C for 30-60 minutes; (3 ) under ultrasonic stirring, sequentially add glyoxal, unsaturated acid salts and persulfates, heat up to 80-100°C, and keep warm for 30-90 minutes; (4) Take out the above-mentioned treated cotton fabrics, wash them, to dry. The cotton fabric obtained by adopting the in-situ non-ironing method of the invention not only has good non-ironing and anti-wrinkle properties, but also has relatively high strength retention.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for in-situ non-ironing finishing of cotton fabrics with acrylic acid and glyoxal. Background technique [0002] Pure cotton fabric is made of cotton as raw material and produced by textile technology, which has the characteristics of moisture absorption, moisturizing, heat resistance, alkali resistance, and hygiene. Pure cotton fabrics are comfortable to wear and have good skin-friendly properties, and are widely favored by people, especially in infant clothing, which is regarded as the safest fabric. However, pure cotton fabrics have poor elasticity and are prone to wrinkling and deformation during wearing and washing, requiring frequent ironing or anti-wrinkle and non-ironing treatment. At present, the more non-ironing method used in industry is: padding cotton fabrics in non-ironing finishing agent for many times, then dehydrating and drying (such as CN105200777A)....
