Problems solved by technology

However, hydrolysis will cause the breakage of the fiber molecular chain and reduce the strength of the fiber, which will have a greater adverse effect on the physical and mechanical properties of the island-fixed superfine fiber synthetic leather. This process is currently only in the research stage of the laboratory.
(2) Low-temperature plasma fiber modification technology. This technology mainly relies on a specific low-temperature plasma device. When the applied voltage reaches the ignition voltage of the gas, gas molecules such as nitrogen and ammonia are broken down, producing

Abstract

The invention provides a method for improving hygienic performance of figured-island superfine fiber synthetic leather, which is characterized by comprising the following steps of: a) treating base cloth of the superfine fiber synthetic leather through collagen and making the collagen fixedly crosslinked to superfine fibers in the superfine fiber synthetic leather; b) penetrating and adsorbing a hydrophilic material in the superfine fiber synthetic leather treated by the collagen; and c) performing finishing treatment on the superfine fiber synthetic leather which is penetrated with the hydrophilic material. By treating the base cloth of the superfine fiber synthetic leather through the collagen and the hydrophilic material, because the collagen and the hydrophilic material have a plurality of hydrophilic groups, the hydrophilcity of the treated superfine fiber surface is equivalent to that of collagen fibers of natural leather, the water vapor permeability and water absorbing capacity of the synthetic leather are improved, and finally a coating with micropores is formed on the surface of the synthetic leather after the finishing treatment on the synthetic leather by using water-soluble polyurethane so as to integrally improve the water vapor permeability and air permeability of the synthetic leather.

Description

technical field [0001] The invention relates to synthetic leather, in particular to a method for improving the hygienic performance of Dingdao superfine fiber synthetic leather. Background technique [0002] The resources of natural leather are limited, and the production process will produce greater pollution. Therefore, the development of artificial synthetic leather with excellent performance has become the pursuit of human beings. In imitation leather, the superfine fiber synthetic leather obtained by impregnating polyurethane with superfine fiber nonwoven fabric with three-dimensional network structure as reinforcement material is close to the internal microstructure, appearance texture, physical properties and people's wearing comfort. Natural leather. According to statistics, as of 2009, the production capacity of China's superfine fiber synthetic leather is about 80 million square meters, and the actual output is about 50 million square meters. More than 90% of the...
