Embodiment 1

[0030] A sericin post-finishing method for cashmere products, comprising the steps of:

[0031] (1) Preparation of crosslinking agent:

[0032] (a) Pre-emulsification: Add an emulsifier in an appropriate amount of deionized water, stir and dissolve, then add the crosslinking monomer, acrylate monomer and N-methylol acrylamide dropwise while stirring within 2 hours to obtain a single Body emulsion; the emulsifier is Tween-80, and the acrylic acid ester monomer includes 45-60% ethyl acrylate, 20-35% butyl acrylate and 20-25% methacrylic acid Methyl ester;

[0033] (b) Polymerization: Add an initiator in an appropriate amount of deionized water, stir and heat up to 75°C, then dropwise add the monomer emulsion obtained in step (1), the reaction temperature is 75-85°C, and react for 1 hour. The agent is added dropwise at intervals, and the dropwise addition is completed within 2 to 3 hours. The temperature is raised to 85°C and the reaction is kept for 1 hour, then the temperatur...

Abstract

The invention discloses an after finishing method for sericin of a cashmere product, which comprises preparation of cross linking agent and a sericin after finishing process. The preparation of cross linking agent comprises steps of pre-emulsification and polymerization, weight percentages of components of the cross linking agent include: emulsifying agent 0.5-2%, cross linking monomer 3-6%, acrylic monomer 30-40%, N-hydroxymethyl acrylamide 1-4%, initiating agent 0.1-0.4%, and deionized water 50-65%. The cashmere product obtained by the invention is excellent in property, fine in washabilityand good in hand feeling, and is novel cashmere with high additional value.

Description

technical field [0001] The invention relates to a finishing method of cashmere products, in particular to a sericin finishing method of cashmere products. Background technique [0002] Cashmere fiber is slender, uniform and soft, good elasticity, and soft luster. Known as "fiber gem", it is a high-grade raw material in the wool textile industry. It can be made into high-end textiles such as cashmere sweaters, scarves, and gloves, and is deeply loved by consumers. At present, three-quarters of the cashmere sweaters in the international market are made in China, but less than 20% of them actually bear Chinese brands. my country's cashmere raw materials have resource advantages, but no brand advantages, and can only rely on cheap labor and resources to earn foreign exchange. Therefore, with the support of new technology and new technology, the development of new products with high added value and high competitiveness has become the key to the success or failure of the current ...
