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. Add 13 parts by weight of a mixture of dimethylaminoethyl methacrylate, hydroxyethyl methacrylate and methyl methacrylate (the mass ratio of the three is 1:1:1), and stir at 50° C. for 30 minutes. Next, under ultrasonic stirring, 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 30 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. Add 10 parts by weight of a mixture of dimethylaminoethyl methacrylate, hydroxyethyl methacrylate and methyl methacrylate (the mass ratio of the three is 1:0.8:1.2), and stir at 40° C. for 60 minutes. Next, under ultrasonic stirring, 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 60 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. Add 15 parts by weight of a mixture of dimethylaminoethyl methacrylate, hydroxyethyl methacrylate and methyl methacrylate (the mass ratio of the three is 1:1.2:0.8), and stir at 60° C. for 20 minutes. Next, under ultrasonic stirring, 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 20 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 field of the textile technology, and discloses an in-situ non-ironing method for finishing cotton fabric through acrylic acid series of finishing agents. The method includes the following steps: (1) adding ethanol into water, adding the cotton fabric, and stirring at 40-60 DEG C for 5-30 minutes; (2) adding acrylate, and stirring at 40-60 DEG C for 10-60 minutes; (3) adding unsaturated acid salt and persulfate in sequence under ultrasonic stirring, increasing the temperature to 80-100 DEG C, and carrying out a reaction under heat insulation for 10-60 minutes; and (4) taking out, washing and air-drying the treated cotton fabric. The cotton fabric obtained by the in-situ non-ironing method has good non-ironing and anti-wrinkle performance and high strength retention.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an in-situ non-ironing method of acrylic series finishing agents for cotton fabrics. 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). Howev...
