Embodiment 1

[0018] In this implementation, the length of the formwork, plank and sponge used is 2 meters, and the width is 2 meters; the thickness of the sponge is 0.5 inches, and the extrusion pressure is 0.5Mp.

[0019] (1) Wash the sheep skin with softened water until the pH value is 5-8, and then squeeze the water on the water squeezer;

[0020] (2) Spread the bare sheep skin on the template after squeezing the water, lay the skin flat naturally, then put the sponge on the bare sheep skin, put the wooden board on the top of the sponge and squeeze it, and then remove the wooden board and sponge; Said template is an aluminum plate engraved with imitation ostrich skin embossed patterns.

[0021] (3) Dip the chemical material with a sponge, put it on the bare sheep skin, squeeze it with a wooden board once to shape it, and then remove the wooden board and sponge; the chemical material is prepared by diluting 5kg of glutaraldehyde with 10kg of normal temperature water .

Embodiment 2

[0023] The template, plank and sponge used in this implementation have a length of 2 meters and a width of 2 meters; the thickness of the sponge is 1 inch, and the extrusion pressure is 0.4Mp.

[0024] (1) Wash the sheep skin with softened water until the pH value is 5-8, and then squeeze the water on the water squeezer;

[0025] (2) Spread the bare sheep skin on the template after squeezing the water, lay the skin flat naturally, then put the sponge on the bare sheep skin, put the wooden board on the top of the sponge and squeeze it, and then remove the wooden board and sponge; Said template is an aluminum plate engraved with imitation ostrich skin embossed patterns.

[0026] (3) Dip the chemical material with a sponge, put it on the bare sheep skin, squeeze it with a wooden board once to shape it, and then remove the wooden board and sponge; the chemical material is prepared by diluting 15kg of glutaraldehyde with 20kg of normal temperature water .

Embodiment 3

[0028] The template, plank and sponge used in this implementation have a length of 2 meters and a width of 2 meters; the thickness of the sponge is 0.8 inches, and the extrusion pressure is 0.3Mp.

[0029] 1) Wash the bare sheep hide with softened water until the pH value is 5-8, and then squeeze the water on the water squeezer;

[0030] (2) Spread the bare sheep skin on the template after squeezing the water, lay the skin flat naturally, then put the sponge on the bare sheep skin, put the wooden board on the top of the sponge and squeeze it, and then remove the wooden board and sponge; Said template is an aluminum plate engraved with imitation ostrich skin embossed patterns.

[0031] (3) Dip the chemical material with a sponge, put it on the bare sheep skin, squeeze it with a wooden board once to shape it, and then remove the wooden board and sponge; the chemical material is prepared by diluting 8kg of glutaraldehyde with 15kg of normal temperature water .

Abstract

The invention discloses a process for producing imitation ostrich grained leather from sheep skin and belongs to the field of leather manufacture. The process comprises the following steps of: (1) cleaning sheep bare skin with softened water and then squeezing with a squeezing machine; (2) spreading the sheep bare skin on a template after squeezing, keeping the skin flat, putting sponge on the sheep bare skin, putting a wood plate on the sponge for compression, and removing the wood plate and the sponge; and (3) dipping the sponge in a chemical reagent, putting the sponge on the sheep bare skin, putting the wood plate for compression, shaping, and removing the wood plate and the sponge. The chemical reagent is obtained by diluting 5 to 15 kg of glutaraldehyde with 10 to 20 kg of room temperature water. The process is simple and feasible, and the imitation ostrich leather product has the advantages of beautiful appearance and low cost.

Description

technical field [0001] The invention relates to an embossing process of sheep skin, in particular to an embossing process of imitation ostrich skin of sheep. Background technique [0002] Ostrich leather is one of the most valuable high-quality leathers in the world. The natural pattern formed by the protruding pores has a special natural feather hole dot pattern. It has good air permeability and its pulling force is 3-5 times that of cowhide. Ostrich skin is not easy to age, durable, can be curled, soft, light, strong tension, good air permeability, wear-resistant, so it is suitable for processing boots, shoes, belts, coats, handbags, briefcases, decorations and expensive furniture, etc. It is considered a symbol of taste, wealth and status. However, ostriches are mostly distributed in Africa and Australia and the output is very low, and its high price is impressive. Therefore, it is imperative to develop a substitute for ostrich skin with similar performance, similar appe...
