Softening agent with high stability, low color change and phenol yellowing resistance and preparation method thereof

Abstract

The invention discloses a softening agent with high stability, low color change and phenol yellowing resistance and a preparation method thereof. The softening agent is prepared from the following components in parts by weight:10-20 parts of alkali-resistant soft sheets, 5-10 parts of a dispersion stabilizer, 10-20 parts of low yellowing block silicone oil, 5-10 parts of phenol yellowing resistance agent and 40-70 parts of deionized water. By optimizing reasonable raw materials, the softener overcomes the difficulty that a cationic softener and an anionic phenol yellowing resistance agent areprone to generating ionic reaction, has good stability, excellent high temperature resistance, shear resistance and soft and comfortable hand feeling, is smaller in color yellowing and is suitable forthe finishing of white or light-colored fabrics; and meanwhile, the softening agent can reach the fourth level in the storage and phenol yellowing resistance effects of cotton and blended fabrics ofthe cotton, and the export requirements are met.

Description

technical field [0001] The invention relates to a softener with high stability, low discoloration and anti-phenol yellow and a preparation method thereof, belonging to the field of textile finishing agents. Background technique [0002] Softener is a conventional auxiliary agent often used in the finishing process of the printing and dyeing industry. It is a textile chemical product that can give clothes and fabrics a smooth and soft feel. At present, the amount of softeners used in my country is large and there are many varieties. They have gradually evolved from traditional fatty acid amide compounds to silicone polymers. However, in actual processing and use, a single variety is often difficult to meet the needs of customers. Non-silicon softeners feel fluffy, cheap, but not smooth enough, high temperature resistance, and alkali resistance are relatively poor: Silicone softeners have excellent hand feel, but are prone to silicone oil spots, and with the increase of ammoni...

Problems solved by technology

At present, the amount of softener used in my country is large, and there are many varieties. It has gradually evolved from traditional fatty acid amide compounds to silicone polymers. However, in actual processing and use, a single variety is often difficult to meet customer needs.

Non-silicon softeners feel fluffy, cheap, but not smooth enough, high temperature resistance, and alkali resistance are relatively poor: Silicone softeners have excellent hand feel, but are prone to silicone oil spots, and with the increase of ammonia value and organic solvents Excessive use, usually the color of the cloth surface becomes larger, and the storage phenol yellow becomes larger during packaging and transportation. This phenomenon seriously plagues the printing and dyeing processing factories.
