AI Technical Summary

Problems solved by technology

Garments bonded with this powder-free base paste have low initial peel strength and fast fading after washing
The original peeling strength of a 2.5cm×10cm cloth strip is about 7N, and it attenuates to about 4N after washing 5 times. The rapid attenuation of the peeling strength affects the quality of the clothing and shortens the service life of the clothing.

Embodiment 1

[0045] First mix 15.2% polyurethane with 60.8% vinyl acetate copolymer emulsion, then add 0.9% polyacrylic acid, and finally add water and ammonia water to adjust the pH value of the solution to about 8. Approximately 22.8% water and 0.3% ammonia are required.

[0046] Vinyl acetate copolymer emulsion is made of vinyl acetate, acrylate copolymer and additives. Its solid content is more than 40%, and its pH value is between 5-6.

Embodiment 2

[0048] First mix 18.0% polyurethane with 61.0% vinyl acetate copolymer emulsion, then add 0.8% polyacrylic acid, and finally add water and ammonia water to adjust the pH value of the solution to about 8. About 20% water and 0.2% ammonia are needed.

Embodiment 3

[0050] First mix 12.0% polyurethane with 65.0% vinyl acetate copolymer emulsion, then add 1.0% polyacrylic acid, and finally add water and ammonia water to adjust the pH value of the solution to about 8. Approximately 21.6% water and 0.4% ammonia are required.

Abstract

The present invention discloses a high-grade double-point undercloth. It is characterized by that on its base cloth a powderless basal slurry can be adopted, and the composition of said powderless basal slurry includes; (by mass%) 12.0%-18.0% of polyurethane, 55.0%-65.0% of vinyl acetate copolymer emulsion, 0.8%-1.0% of polyacrylic acid, 0.2%-0.4% of ammonia water and 20.0%-26.0% of water. The adoption of vinyl acetate copolymer emulsion and ammonia water in said powderless basal slurry can greatly raise initial peeling strength of garment, and can raise garment quality.

Description

technical field [0001] The invention relates to an interlining for clothing, in particular to a high-grade double-dot interlining. Background technique [0002] In order to improve the quality of clothing, most of the clothing currently uses fusible interlinings. [0003] Earlier fusible interlinings used single-point base pulp, which had poor adaptability when pressing and bonding fabrics. In order to improve the bonding performance of the interlining, people have adopted a double-point base slurry, and the garments that are hot-melt bonded with the double-point slurry are resistant to dry cleaning, washable, and the peel strength is also improved to a certain extent. [0004] The current powder-free base paste uses polyurethane and polyacrylate, and then adds a small amount of polyacrylic acid and water after the ratio. Garments bonded with this powder-free base paste have low initial peel strength and fast decay after washing. The original peeling strength of a 2.5cm×1...
