Problems solved by technology

At present, three-quarters of the cashmere sweaters in the international market are made in China, but less than 20% of the cashmere sweaters actually bear Chinese brands.
However, the resulting textiles have a rough hand and poor wash fastness

Embodiment 1

[0030] A sericin finishing method for cashmere products, including the following steps:

[0031] (1) Preparation of crosslinking agent:

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

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

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 washability and good in hand feeling, and is novel cashmere with high additional value.

Description

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