Problems solved by technology

[0006] But the above-mentioned imitation cowhide bonded with the cow fiber leather base cloth and the polyurethane coating layer has the following disadvantages: the one is that the tensile strength is not high, and the bonding strength between the layers is low, and it is easy to peel off after a long service time; The surface flatness of the base fabric is not high, which affects the appearance quality of the base fabric after the surface is bonded with the coating layer; the third is that the softness is not good and the hand feel is poor
This affects the final performance and quality of the simulated cow leather products

Embodiment Construction

[0052] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0053] Such as Figures 1 to 2 Shown is the embodiment of the aftertreatment process of a kind of water-based kraft leather base cloth of the present invention, comprises following processing steps:

[0054] Step 10, softening treatment: using the bovine fiber leather base cloth as a raw material, adopting a through-type shock softening production line, performing a shock softening treatment on the bovine fiber leather base cloth, so that the bovine fiber leather base cloth is softened;

[0055] Step 20. Impregnation treatment: use water-based PU material and roller coating equipment to infiltrate the front of the cow fiber leather base cloth after shock t...

Abstract

The invention relates to the technical field of leather manufacturing and discloses an aftertreatment process of waterborne flyleather base cloth. The process includes steps: vibration softening treatment, impregnating treatment, drying after impregnating, leveling and drying after leveling, wherein the step of impregnating treatment includes adopting a waterborne PU material and roller coating equipment to perform single-side feeding permeation on the front of flyleather base cloth after going through vibration softening treatment and controlling the depth at which the waterborne PU materialpermeates into the flyleather base cloth to be 1 / 4-3 / 4 of the thickness of the flyleather base cloth. Through two times of treatment on the flyleather base cloth, bonding strength of the flyleather base cloth is further improved while good performance of the same is maintained, so that flyleather gray cloth formed by after treatment can be used for subsequently making intermediate products of high-performance simulated cowhide, and final performance and quality of simulated cowhide leather products are improved.

Description

technical field [0001] The invention relates to the technical field of leather manufacturing, in particular to a post-treatment process of water-based calf leather base cloth. Background technique [0002] Leather is an indispensable category of production and daily necessities in human life, and is widely used in many fields such as clothing, home furnishing, automobiles, and public services. A large number of scraps of natural leather are produced in the production process of leather products, and the amount of scraps of natural leather is large. If it can be used twice, especially processed into cow fiber leather, it will produce Considerable wealth, and at the same time have positive significance for green energy conservation and environmental protection. [0003] The traditional regenerated leather is to crush all kinds of leather and animal skin scraps into powder, and then bond and press the powder into a whole piece of regenerated leather through adhesives or hot-me...
