Abstract

The invention discloses a preparation method of an anti-felting woolen overcoat. The preparation method comprises the following steps: adding adipic acid, ethyltriethoxysilane, o-hydroxybenzoate, ethyl acrylate, dodecyl trimethoxysilane, guar gum hydroxypropyl trimethyl ammonium chloride, hexamethylenediamine dodecyl sulfate, methylcyclosiloxane and double carboxyl-terminated polyethylene glycol into a reactor, heating to react under the protection of nitrogen, then adding didecyl dimethyl ammonium chloride, natural saponin, titanium isopropoxide and phosphorous acid, carrying out vacuum reaction for 2-3 h, cooling to 70 DEG C after the reaction, and stopping the reaction to obtain a finishing agent; and soaking the woolen overcoat in the finishing agent for padding, drying the padded woolen overcoat, and baking the woolen overcoat after drying. The preparation method is simple in production process and low in manufacturing cost, the finished woolen overcoat has excellent anti-felting performance and high strength retention rate, meanwhile can keep the original flexibility and hand feeling of the woolen overcoat, and has the characteristics of washing resistance, safety and harmlessness.

Description

technical field [0001] The invention relates to a preparation method of an anti-felting woolen overcoat. [0002] technical background [0003] With the development of the times and the continuous improvement of people's living standards, health and fashion are a way of consumption that people pursue. Existing common fabrics can no longer satisfy people's needs. Clothes that are comfortable, versatile and easy to care for are becoming more and more popular with consumers. Therefore, consumers have higher and higher requirements for comfort, multi-function and easy care of fabrics. Woolen coat, a thicker and denser woolen fabric. The fabric is very popular in the autumn and winter market because of its novel and unique style, crisp yet soft, simple yet fashionable, rough yet elegant. Woolen fabrics cannot be washed with water. Washing is prone to hair loss, shrinkage and deformation. In today's extremely tense pace of life, people don't want to spend too much time and t...
