Abstract

The invention discloses an antistatic finishing agent for a wool fabric and a preparation method thereof, the preparation method comprises the following steps: taking a polyurethane emulsion, heatingup to 80 to 90 DEG C, dropwise adding a pre-emulsion and an initiator into the polyurethane emulsion, continuing reflux and heat preservation reaction for 2-3h after the completion of the dropwise addition of the pre-emulsion and the initiator, adding citric acid to adjust the pH to 3-4, adding polyethylene glycol-200, stirring for reaction for 1-2h, adjusting to neutral, adding water to dilute, sieving, adding dodecyl diphenyl ether disulfonate ammonia, stirring and mixing uniformly, then cooling to room temperature, and removing air bubbles to obtain the antistatic finishing agent for the wool fabric. The wool fabric after being finished by the antistatic finishing agent has good antistatic property, is easy to process, reduces static electricity generation during use, has good water washing and abrasion resistance, and has a long service life.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to an antistatic finishing agent for wool fabrics and a preparation method thereof. Background technique [0002] Wool fiber has the advantages of good elasticity, good warmth retention, and strong hygroscopicity. It has been widely used in various textile raw materials, and plays an increasingly important role in textile processing. Wool fabric has the characteristics of full texture, good drapability, smooth hand feeling, light and comfortable wearing, etc., and is favored by consumers. With the improvement of people's living standards, consumers have higher and higher requirements for the comprehensive performance of traditional wool fabrics, requiring them to not only have a soft and slender feel, but also have a crisp shape. Inside the wool fiber is the hair shaft, which is composed of a variety of amino acids through peptide bond chains as the main chain of protein polymers...
