Problems solved by technology

[0006] But the main problem that the above-mentioned imitation cowhide that exists with bovine leather base cloth and polyurethane coating layer bonding is following drawback: the one, tensile strength is not high, and the cohesive strength between the layers is low, and it is easy to peel off after using for a long time ; Second, 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

[0044] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following examples are for more clearly explaining the technical solutions of the present invention without limiting the scope of the invention.

[0045] like Figure 1 to 3 The present invention is shown in a special soft cow leather fiber manufacturing process embodiment, comprising the process steps:

[0046]Step 10, preparing bovine leather semifinished fiber: fiber by bovine Pi Jibu PU film and bonding process, the film obtained after bovine semifinished fiber skin;

[0047] Step 20, back to the oil formulation: The deionized water, softened leather softening oil, lanolin, penetrating agents, mildew oil mixture, formulated as oil back;

[0048] Step 30, back to the oil treatment: The back roller and fluid and equipment, the surface of the bovine leather semifinished simplex fiber treated with oil, the one surface treated with oil refers to oil back semifinished fiber skin applied to cattle the reverse side (i.e. the ...

Abstract

The invention relates to the technical field of leather manufacturing, and discloses a process for preparing extra-soft bovine leather, comprising the following process steps: step 10, preparation of semi-finished bovine leather; step 20, preparation of return oil: mixing ionized water, leather For softening, mix softening oil, lanolin, penetrating agent, and anti-mold oil to prepare a return oil; step 30, oil return treatment; step 40, timing penetration; The infiltrated semi-finished bovine fiber skin is placed in the drum body of the softening device, mixed with a number of beat balls, and the drum body is rotated to beat the semi-finished bovine fiber skin; step 60, trimming. The invention improves the bonding strength of the base fabric and the PU film in the bovine fiber leather product, and improves the softness of the bovine fiber leather product.

Description

Technical field [0001] The present invention relates to the technical field of leather manufacture, particularly to a soft bovine Laid fiber skin preparation. Background technique [0002] Leather is an integral part of human life in a large class of production and living necessities, it is widely used in apparel, home, car, public services and other areas. A large number of natural leather produced in leather production process Scraps, odd bits of the number of large natural leather, can be subjected to secondary use such as, in particular, secondary processing into fiber skin cow, will be generated considerable wealth, while producing a positive meaning for green energy and environmental protection. [0003] The conventional regeneration of leather and leather are of animal skin scrap pulverized into powder, and then by an adhesive or a hot-melt adhesive fiber powder, pressed into a piece of regenerated leather. This regeneration leather hygroscopicity, permeability, etc. feel ...
