Figured island fiber and preparation method of imitated leather

Abstract

The invention belongs to the technical field of superfine fiber synthetic leather and imitated leather, and in particular relates to figured island fiber and a preparation method of the imitated leather. Island composite components of the figured island fiber provided by the invention contain protein. The method for preparing the imitated leather from the figured island fiber, provided by the invention, comprises the following steps of 1, preparing the figured island fiber; 2, preparing non-woven cloth; 3, preparing synthetic leather; 4, preparing the imitated leather. The figured island fiber and synthetic leather base cloth prepared from the figured island fiber have protein components by adding animal protein into the island composite components, grease can be effectively kneaded and filled by using a processing technology during the after-treatment of the base cloth, and highly-imitated leather which is full, oily and pendulous can be prepared.

Description

technical field [0001] The invention belongs to the technical field of superfine fiber synthetic leather and imitation leather, and in particular relates to a preparation method of fixed island fiber and imitation leather. Background technique [0002] The whole process of leather breeding, slaughtering, and leather production consumes a lot of manpower, material resources and resources, and also produces a lot of waste gas and waste water, which is difficult to treat and endangers the environment. At present, the whole world is controlling the production of leather, and in order to satisfy people Love for genuine leather products, and at the same time seek materials that can replace genuine leather, among which imitation leather is one of them. [0003] At present, the fibers of superfine fiber synthetic leather are divided into indeterminate island type and fixed island type. Indeterminate island microfibers usually use PA6 (polyamide) as the island component and PE (poly...

AI Technical Summary

Problems solved by technology

[0005] This technology can not only improve the softness of microfiber synthetic leather, but also improve the strength of microfiber synthetic leather to a certain extent. However, since the island component of the fixed island fiber produced in the prior art is only a single component, PA6 is often used. Or PET, even if this post-finishing technology is used for fatliquoring treatment, its components cannot be connected with the fatliquoring agent, and the fusion effect of the fatliquoring agent and the synthetic leather base fabric is poor, and it is difficult to achieve the expected effect

The use of fatliquoring technology is limited, so that the style and feel of synthetic leather produced in the prior art are quite different from genuine leather, and there are disadvantages such as no greasy feeling, no plumpness, and no drape, which limits the application of microfiber artificial leather to high-end fields, The process of completely replacing the dermis

[0006] At present, there is no report of using protein to make fixed island fiber and imitation leather
