Embodiment 1

[0032] 1. Dissolution of cyanuric chloride

[0033] In a reaction flask equipped with a stirrer and a thermometer, add cyanuric chloride [select 20.24g (0.1mol)], and dissolve it with a mixture of acetone and ice water [select 20mL ice water and 10mL acetone] (i.e., acetone aqueous solution) , and mechanically stirred for 10 minutes to promote its full dissolution.

[0034] 2. Add m-phenylenediamine disulphonic acid [choose 13.4g (0.05mol)] into 40mL water, under the condition of stirring, slowly (3min) add sodium carbonate (0.05mol) powder equal to the substance amount, after the sodium carbonate powder is added , and continue to stir for 5 minutes, so that the m-phenylenediamine disulphonic acid becomes sodium m-phenylenediamine disulphonate, and a sodium m-phenylenediamine disulphonate solution is obtained.

[0035] 3. Slowly add m-phenylenediamine disulphonate sodium solution dropwise into the three-necked flask dissolved with cyanuric chloride system to carry out the fir...

Abstract

The invention discloses a crease resisting agent for cotton. The crease resisting agent is a compound with a structure described in formula I or II, can be applied to cotton fabrics, and can be particularly applied to pure cotton fabrics. Hetero active polyfunctional groups in molecules of the crease resisting agent for the cotton and hydroxide radicals of cotton fibers are subjected to chemical crosslinking to generate a network structure to prevent the slippage of fiber macromolecules and improve the washable crease resistance of the cotton fabrics. The invention also discloses a preparation method of the crease resisting agent for the cotton. Raw materials are easy and simple to obtain, and the synthetic process is simple and easy to implement.

Description

technical field [0001] The invention relates to the field of fabric anti-wrinkle agents, in particular to an anti-wrinkle agent for cotton, a preparation method thereof and an application in cotton fabrics. Background technique [0002] Cotton fabrics have many excellent wearing and wearing properties, such as moisture absorption and breathability, soft touch, economical benefits, and comfortable wearing. However, cotton fabrics are prone to wrinkling during wearing. With the improvement of science and technology and production and living standards, the anti-wrinkle finishing of cotton fabrics has become an important process to improve the fabric's wearing performance and its added value, and is an important field of dyeing and finishing production. The traditional anti-wrinkle finishing of cotton fabrics mostly uses N-methylol finishing agents. After finishing, the anti-wrinkle effect is ideal and the cost is low, but there is a problem of formaldehyde release. , Anti-wrin...
