Embodiment 1

[0026] 1) Retanning, dyeing, squeezing and stretching, stretching, scalding, and softening are performed on sheep shearing fur according to conventional techniques.

[0027] 2) Leather Grinding—Grinding with small grinding wheel 400# or 600#, there is no obvious meat residue, and the pile is uniform. Dust removal machine.

[0028] 3) Ironing shearing - spraying water on the wool surface, passing through the ironing machine at 180°C with flat rollers, and shearing machine to cut floating wool.

[0029] 4) Stretch the board according to the conventional process.

[0030] 5) Dust removal on the board surface - the compressed air pipe blows off the board dust.

[0031] 6) Spray primer - mix 90g color-changing wax WX-093, 40g resin BR-112, 40g dye water LP-4235 and 20g water (190g each) for each part to make an emulsion. Spray on the skin, about 100g / sheet, and dry at 130°C. Let it stand for 4-6 hours, and iron it with an ironing machine at 100°C, with an ironing pressure of 5-...

Embodiment 2

[0036] 1) Retanning, dyeing, squeezing and stretching, stretching, scalding, and softening are performed on sheep shearing fur according to conventional techniques.

Abstract

The invention provides a preparation method for chenille wax change effect leather. The preparation method comprises the following steps that (1) chenille fur after retanning and dyeing is neatened for the first time; (2) the fur after processing in the first step is subjected to staking and leather buffing and then is neatened for the second time; (3) a top side of the fur after processing in the second step is subjected to butt oar spraying, color paste spraying and top oar spraying in sequence; (4) after the fur after processing in the third step is milled, the wax change effect leather is obtained. A wax color change effect glaze can be obtained from a chenille flesh side. A product has good color fastness to light, dry and wet rubbing color fastness and PVC transfer resistance.

Description

technical field [0001] The invention relates to a preparation method of sheep shearing wax all-effect leather, which belongs to the technical field of fur processing and finishing. Background technique [0002] The waxing effect is processed by the waxing process to reflect the original natural texture and luster of the leather. With use, the skin texture will also appear wrinkled and uneven. [0003] Now the wax effect products mainly include leather oil wax sofa and sheep leather wax clothing. Due to the existence of the wool surface of sheep shearing, the grain surface is hidden. If some effects are to be done, it can only be done on the flesh side of the leather and cannot be done on the grain layer of the leather. But the meat surface has no natural texture and no protection from the dermis. During production, there are problems such as thick and uneven pile, fast penetration of chemical materials, etc., and it is difficult to make wax effect on the meat surface. C...
