Problems solved by technology

[0003] Upper leather is usually used as the surface material of daily necessities, but due to the characteristics of the material itself, pigskin leather has large pores, rough surface, and large differences in fiber structure, and the gloss of the obtained leather is not high, especially Although the material cost of the second-layer pigskin material is lower than that of the first-layer pigskin, its pores are large, and local skin embryos may even have uneven defects. The material fineness of the second-layer pigskin material is not enough and the gloss is poor, so only It can be used to make the inner lining of the leather, but cannot be used as the surface material of the product, the application range is limited, and the economic benefit of the leather is not high

Embodiment 1

[0057] The leather processing method of making top leather from lining leather in this embodiment includes the following steps:

[0058] (1) Material selection: select lining materials;

[0059] (2) First spin-off: Put the selected lining into a drum for spin-off processing to destroy the dermal tissue fibers of the lining and make the leather soft;

[0060] (3) Paste particle film: paste a layer of particle film on the leather surface;

[0061] (4) Spray adhesive resin: spray adhesive resin material on the surface of the particle film to form an adhesive resin layer;

[0062] (5) Pasting metal film: Paste a metal film on the surface of the resin layer;

[0063] (6) The second spin-off: Put the metal film-laminated leather into a rotating drum for spin-soft processing, so that the grain surface of the leather is exposed;

[0064] (7) Spray color rubbing: spray color rubbing paint on the soft leather material for the second time;

[0065] (8) Polishing: Throw away the raised parts of the le...

Embodiment 2

[0072] The difference between this embodiment and embodiment 1 is that the adhesive resin of this embodiment is composed of the following parts by weight of raw materials:

[0073] 50 parts of ethyl orthosilicate, 10 parts of aliphatic hydrocarbons, 10 parts of lower alcohols, 3 parts of titanate-silane coupling agent.

[0074] Among them, the rubbing paint is a mixture of wax agent and nitrocellulose in a mass ratio of 3.5:6.5. The wax agent is composed of the following parts by weight of raw materials:

[0075] PE wax 12 parts

[0076] Polishing wax 22 parts

[0077] Tween 80 4 parts

[0078] Six polyglycerol monostearate 11 parts

[0079] 9 parts of polyolamine

[0080] Sodium dodecylbenzene sulfonate 12 parts

[0081] 160 parts of deionized water.

[0082] Among them, the fixing resin is cetylpyridinium chloride.

[0083] The rest of the content of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Embodiment 3

[0085] The difference between this embodiment and embodiment 1 is that the adhesive resin of this embodiment is composed of the following parts by weight of raw materials:

[0086] 52 parts of ethyl orthosilicate, 12 parts of aliphatic hydrocarbons, 12 parts of lower alcohols, 5 parts of titanate-silane coupling agent.

[0087] Among them, the rubbing paint is a mixture of wax agent and nitrocellulose in a mass ratio of 4:6. The wax agent is composed of the following parts by weight of raw materials:

[0088] PE wax 15 parts

[0089] Polishing wax 25 parts

[0090] Tween 80 3.5 parts

[0091] Six polyglycerol monostearate 10 parts

[0092] 9 parts of polyolamine

[0093] Sodium dodecylbenzene sulfonate 13 parts

[0094] 170 parts of deionized water.

[0095] Among them, the fixing resin is a mixture of a binary copolymer of cetylpyridinium chloride, acrylamide and acrylic acid in a mass ratio of 1:3.

[0096] The rest of the content of this embodiment is the same as that of Embodiment 1, and...

Abstract

The invention relates to the technical field of leather processing, and specifically relates to a leather processing method for preparing upper leather from lining leather. The leather processing method comprises the following steps: (1) selecting material; (2) softening the leather through swinging for the first time; (3) pasting a granular film; (4) spraying adhesive resin; (5) pasting a metal film; (6) softening the leather through swinging for the second time; (7) spraying brush-off paint; (8) polishing; (9) fixing the color; (10) softening the leather through swinging for the third time to obtain finished product of leather. The provided method can prepare upper leather from lining leather, the obtained leather has the characteristics of upper leather and also has a metal effect; moreover, the surface of the leather blank is covered by the granular film and metal film, the defects on the surface is covered, the bad lining leather is converted into high quality leather material, which is bright, high-end, beautiful, and fashion, and the additional value is greatly increased.

Description

Technical field [0001] The invention relates to the technical field of leather processing, in particular to a leather processing method for making top leather from lining leather. Background technique [0002] In the prior art, leather is widely used on the surface of civilian products, such as tables and chairs, sofas, shoe materials, clothing, etc., to increase the texture, beauty, or durability of the civilian products. Leather can be roughly divided into artificial leather and natural leather. Natural leather refers to the production of animal fur and drying, washing, softening, dyeing, trimming, cutting, etc., to form a smooth surface and tough leather [0003] Noodle leather is usually used as the surface layer material for civilian products, and pigskin leather has large pores, rough surface, and fibrous tissue due to the characteristics of the material itself, and the gloss of the obtained leather is not high, especially Although the material cost of the second-layer pigs...
