Problems solved by technology

However, composite yarns containing animal fibers such as wool are difficult to manage and are prone to pilling. Moreover, the fabrics made of such composite yarns are prone to moths, bacterial and viral infections, and in severe cases will lead to deterioration of sanitary conditions and spread of disease
In order to avoid the above problems and improve the anti-moth performance and easy-care performance of the composite yarn, the composite yarn is usually treated with a finishing agent and an anti-moth agent that are convenient for the composite yarn. This method increases the processing steps and processing of the composite yarn. cost, use effect is not good

Embodiment 2

[0046] In parts by weight, after stirring 12 parts of polyethylene glycol and 6 parts of isophorone diisocyanate evenly, slowly add 0.8 parts of dibutyltin dilaurate, and then stir and react at 60°C to obtain a prepolymer; Add the prepolymer dropwise to 55 parts of hydroxyalkyl silicone oil. After the dropwise addition is completed at 22°C, raise the temperature to 70°C and react for 3 hours to obtain component A; mix components A and B evenly at 60°C, To obtain a finishing agent, component B includes: 80-200 parts of mixed extracts of Galla chinensis, flavescens and dandelion, the mass ratio of components A and B is 1:2.5; , and the coating formed by spraying the above-mentioned finishing agent on the surface of the polyester fiber, and then twisting and combining the coated wool, rabbit hair, brushtail possum hair, and polyester fiber to form a composite yarn, which is used to make into ready-to-wear fabrics.

[0047] The mixed extract of gallnut, flavescens and dandelion i...

Embodiment 3

[0050] In parts by weight, after stirring 15 parts of polyethylene glycol and 6 parts of isophorone diisocyanate evenly, slowly add 1.5 parts of dibutyltin dilaurate, and then stir and react at 65°C to obtain a prepolymer; Add the prepolymer dropwise to 70 parts of hydroxyalkyl silicone oil. After the dropwise addition is completed at 28°C, raise the temperature to 75°C and react for 2 hours to obtain component A; mix components A and B at 80°C evenly, Finishing agent is obtained, B component includes: 150 parts of mixed extracts of Galla gall, Sophora flavescens and Dandelion, the mass ratio of A component and B component is 1:4; Spray above-mentioned finishing agent on wool and brushtail possum hair The formed coating is then twisted and combined with wool, brushtail possum hair, acrylic and polyester fibers to form a composite yarn, and the composite yarn is used to make a garment fabric.

Abstract

The invention discloses a mothproof and easy-to-finish composite filament and garment fabric. The composite filament comprises animal fiber and synthetic fiber, a coating formed by a finishing agent is formed on the surface of at least one of the animal fiber and the synthesis fiber, the finishing agent comprises a component A and a component B, in parts by weight, the component A comprises 10-30parts of polyethylene glycol, 0.5-3 parts of a catalyst, 5-10 parts of isocyanate and 30-100 parts of hydroxyalkyl silicone oil; the component B comprises 80-200 parts of a mixed extract of Chinese gall, radix sophorae flavescentis and herba taraxaci; the mass ratio of the component A to the component B is 1:(2-10). The composite filament is better in flexibility, easy to maintain and long in mothproof effect and has bacteriostatic and antibacterial effect.

Description

technical field [0001] The invention relates to textiles, in particular to a moth-proof and easy-to-finish composite yarn and a garment fabric. Background technique [0002] Fabrics containing natural ingredients such as wool and mink hair are comfortable to wear and have good warmth retention properties, and are welcomed by more and more people. However, composite yarns containing animal fibers such as wool are difficult to manage and are prone to pilling. Moreover, the fabrics made of such composite yarns are prone to moths, bacterial and viral infections, and in severe cases will lead to deterioration of sanitary conditions and The spread and spread of disease. In order to avoid the above problems and improve the anti-moth performance and easy-care performance of the composite yarn, the composite yarn is usually treated with a finishing agent and an anti-moth agent that are convenient for the composite yarn. This method increases the processing steps and processing of th...
