Abstract

The invention relates to a mercerized wool smoothing finishing agent and a preparation method thereof, and belongs to the technical field of detergents. An amino-modified silicone smoothing agent canbe synthesized from octamethylcyclotetrasiloxane, aminoethylaminopropyl polydimethyl siloxane, silane coupling agent HD-109 and silane coupling agent HD-110 as raw materials through bulk polymerization under the action of a catalyst, and excellent soft and smoothing effects can be obtained. The method adopts multi-amino coupling agents for bulk polymerization, the synthesis and emulsification process is simple, easy to operate and suitable for industrial production, and a silicone oil molecular chain contains more secondary amino groups and tertiary amino groups, can effectively reduce the amount of active hydrogen and greatly reduces the yellowing of a fabric. The protein structure contained in the mercerized wool smoothing finishing agent has a good affinity with a wool scale layer structure, can promote fiber swelling, reduces the dynamic friction coefficient and the static friction coefficient of wool, thereby playing the role of smoothing and elasticity, and the mercerized wool smoothing finishing agent does not affect the softness of the fabric, has good hand feeling, and has broad application prospects.

Description

technical field [0001] The invention relates to a mercerized wool smoothing agent and a preparation method thereof, and belongs to the technical field of washing products. Background technique [0002] Cashmere fabric has a soft and smooth feel, and good elasticity, which has won the favor of consumers. However, the production of cashmere known as soft gold is extremely limited, and the cashmere production of a cashmere goat is only 50-80g / year. Although my country's cashmere production accounts for 75% of the world's total output, it is only 12,000 tons per year. [0003] In the textile printing and dyeing industry, silicone smoothing agents can give plush fabrics, leather fabrics, and cotton fabrics a smooth feel. With the improvement of people's living standards, high-grade blanket fabrics, clothing fabrics and leather fabrics are not only required to feel soft and smooth, but also have higher requirements for the color and brightness of the fabric visually. In general...
