Production process of full-chinlon leather base cloth

Abstract

The invention belongs to the technical field of full-chinlon leather base cloth, and particularly relates to a production process of full-chinlon leather base cloth. A needling machine comprises a supporting frame; a first supporting plate is fixedly connected to the upper portion of the supporting frame; first driving mechanisms which are uniformly arranged are rotationally connected to the inside of the inner wall of the first supporting plate through a motor; each of the two first driving mechanisms comprises first cranks; the two first cranks on each first driving mechanism are rotationally connected with first supporting rods; and the sides, which are opposite to each other in pairs, of the first supporting rods are fixedly connected with first needle plates on the bottom surfaces ofthe first supporting rods. The production process is mainly used for solving the problems that an existing needling machine often adopts a long needling production line to carry out needling treatmenton chinlon fibers, then needling of the chinlon fibers can be more thorough, however, the needling machine moves difficultly due to the fact that the occupied area is large, meanwhile, if a needlingstructure at a certain position of the needling machine is damaged, the needling degree of chinlon can be influenced, and then the needling efficiency of the chinlon fibers can be reduced.

Description

technical field [0001] The invention belongs to the technical field of full nylon leather base cloth, in particular to a production process of full nylon leather base cloth. Background technique [0002] Since the beginning of the 21st century, with the scarcity of natural leather resources and the rapid development of synthetic leather technology, more nonwoven products have been well applied, especially products represented by needle-punched leather base fabrics. Its inherent imitation leather structure is recognized by more leather manufacturers and customers. At present, 240 million meters of needle-punched leather base fabrics are needed every year in China alone, and some high-end products need to be imported. As medium-to-high-end synthetic leather products, such as medium- and high-stripping products, most of them are made of polyester-nylon fiber blends and superfibers. Or carry out certain post-processing on the needle-punched leather base fabric. These medium an...

Problems solved by technology

[0006] In order to make up for the deficiencies in the prior art, the present invention proposes a production process for all-nylon leather base cloth. The present invention is mainly used to solve the needling machines in the prior art that often use longer needle-punching production lines to process nylon fibers. Acupuncture treatment can make the nylon fiber needling more thoroughly. However, this kind of needling machine is difficult to move due to its large footprint. At the same time, if the needling structure of the needling machine is damaged, it will affect the degree of needling of the nylon. This will reduce the needling efficiency of nylon fibers
