Artificial leather, artificial leather base cloth and manufacturing method thereof

Abstract

The invention provides artificial leather, artificial leather base cloth and a manufacturing method of the artificial leather base cloth, and belongs to the field of synthetic leather, and the manufacturing method comprises the following steps: firstly, a weaving cloth taking sea island superfine fibers as main materials is compounded with a non-weaving cloth by needling, the sea part is removed by fiber splitting, then the base cloth is compounded with genuine leather fibers by spunlace to form a soft base cloth with high tensile property, the surface layer is processed on the base cloth in a veneering or coating mode, and the dermal fibers in the leftover materials left after animal skin processing are recycled and fully utilized, so that the dermal fibers and the superfine fibers are subjected to composite processing to form the artificial leather with the strength, the tensile property, the air permeability and other properties and the hand feeling close to those of natural leather. In addition, the leather fibers are used in an organic combination mode, processes such as PU impregnation and the like are not needed, and the leather fibers are renewable and more environmentally friendly compared with an existing process.

Description

technical field [0001] The invention relates to the field of artificial leather, in particular to an imitation leather, an imitation leather base cloth and a manufacturing method thereof. Background technique [0002] At present, microfiber fiber is widely used as the raw material of artificial synthetic leather to process synthetic leather with high simulation degree, but its skin affinity is poor. At the same time, in the process of real leather production and processing, a large amount of animal skin scraps will be produced. The current mainstream method is to crush the animal skin scraps and add chemical raw materials to mix them into imitation leather. This kind of synthetic leather is rough in workmanship and stretch-resistant. Performance, air permeability are all relatively poor. [0003] The Chinese invention patent with the patent application number CN201710222285.7 discloses a production method of leather fiber composite superfiber synthetic leather, which is obt...

AI Technical Summary

Problems solved by technology

[0004] The inventor of the present application has been engaged in the manufacture of artificial leather for a long time, and he found that the concept of producing synthetic leather proposed by the above patent had relevant tests and samples in the industry in 2003 and 2004, and found that there are mainly the following problems: 1. The production method It is to violently mix the leather fiber into the superfine fiber, and process and produce it according to the superfine fiber synthetic leather processing method. The finished product has a loose structure, tensile strength, and rebound performance after deformation. Not only is it not as good as the real leather, but it is more The imitation leather obtained by only using superfine fibers is even worse, and cannot meet actual needs.

2. This production method involves multiple processes such as impregnation, curing, drying, and weight reduction. The above-mentioned processes are complicated and the production cycle is long, so it is not suitable for mass production; moreover, in the above-mentioned process, the body structure of the leather fiber will be destroyed and cannot be used. has an effect

Therefore, the above-mentioned patents are difficult to meet the actual use needs and cannot be mass-produced, so they have not been put into mass production for a long time.
