Problems solved by technology

At present, the base fabrics of artificial leather and synthetic leather mainly include the following types: woven fabrics, knitted raised fabrics, and some filament product base fabrics, but these base fabrics all have poor tensile strength, low tear strength, vertical and horizontal Disadvantages such as uneven tearing strength, poor flatness, poor peeling, and poor air permeability lead to poor finish, poor air permeability, poor hand feel and imitation of the finished leather

Abstract

The invention discloses a highly air permeable and highly tearing fine denier yarn spunlace novel material and a production technique thereof, which pertains to the technical field of textile materials. The novel material is produced by the following components according to weight percentage: 70 percent of highly hydrophilic polyester with the specification of 1.56dtex multiplied by 38mm and 30 percent of nylon with the specification of 1.56dtex multiplied by 38mm. The highly air permeable and highly tearing fine denier yarn spunlace novel material has good stretching strength, the ratio of MD to CD equal to 1:1, even vertical and horizontal tearing strength, good uniformity, even thickness, no fuzz, stable peeling, good winding effect, comfortable touch feeling and low formaldehyde content, and improves the simulation quality and the air permeability of a product after becoming finished leather; the product is mainly used as the base fabric of PU leather.

Description

technical field [0001] The invention discloses a high-breathability and high-tear fine-denier spunlace novel material and a production process thereof, which belong to the technical field of textile materials. Background technique [0002] Since my country's reform and opening up, the speed of national economic development has been increasing day by day, people's material and spiritual and cultural living standards have been significantly improved, people's demand for daily necessities has developed from simple usability to both beautiful and affordable, especially in clothing, shoes There is an obvious consumption concept in categories and bags. During the period from 1980s to 1990s, mad cow disease appeared continuously in some European countries, which caused a big discount in the leather market and provided a great opportunity for the development of artificial leather and synthetic leather. With the obvious expansion of the artificial leather market and synthetic leather...
