Problems solved by technology

The advantage of solvent-based wet-laid garment leather is that the product provides a good feel and feel, and the price of the product is very cheap, and the cost can be controlled within a very low range; but solvent-based wet-laid garment leather contains a large amount of wood powder , will greatly affect the performance of the bass, including the anti-aging problem of the bass, so the solvent-based bass garment leather will appear pulverization when it is placed for one year
Moreover, due to the limitation of the tension of the solvent-based wet production line, the solvent-based wet method cannot make high-resilience and high-stretch garment leather
[0004] In view of the fact that the solvent-based wet method cannot achieve high-resilience and high-stretch garment leather, the solvent-based method uses a dry method to laminate the base fabric with 3 knives. Achieve the sensuality of wet-laid bass garment leather

Abstract

The invention provides high-springback high-stretching clothing leather and a preparation method thereof.The method includes the following steps that 1, after release paper is directly coated with size of a surface layer, hot air drying is conducted, and cooling is conducted; 2, coating of size of a foaming middle layer is conducted, hot air drying is conducted, and cooling is conducted; 3, coating of size of a bottom layer is conducted, then base cloth is laminated through a laminating machine, then hot air drying is conducted, and cooling is conducted; 4, the release paper is stripped, and the high-springback high-stretching clothing leather is obtained.The obtained high-springback high-stretching clothing leather perfectly combines the elasticity of four-directional elastic fabric and the elasticity of a polyurethane layer, and the leather is soft in handfeel, resistant to wrinkling, high in real leather sense and especially sufficient in elastic force, and can meet the requirements of the clothing leather market for elastic clothing leather.

Description

technical field [0001] The invention relates to the technical field of garment leather production technology, and specifically discloses a high-resilience and high-stretch garment leather and a preparation method thereof. Background technique [0002] Garment leather has a good feel and is widely used in coats, underwear, etc. With the changes in the market and the improvement of consumer tastes, the requirements for the grade of garment leather are getting higher and higher. The quality of traditional garment leather can no longer meet the needs of consumers. Demand, the development of high-grade garment leather is an inevitable direction. [0003] All the four-way stretch garment leathers in the market are solvent-based wet-laid bass garment leather and solvent-based dry-laid veneer garment leather. The advantage of solvent-based wet-laid garment leather is that the product provides a good feel and feel, and the price of the product is very cheap, and the cost can be cont...
