Problems solved by technology

Although the current leather products are various and have their own advantages, they also have disadvantages. For example, the thickness of ultra-thin leather is below 0.2-0.3mm, and its physical tear strength and fastness are also due to its thickness. It becomes thinner and worse, and it is like making leather into underwear, which is not as safe, hygienic, comfortable and healthy as cotton and silk when worn on the body.

Embodiment Construction

[0011] Coat the polyamide hot melt adhesive with gravure screen printing, and print it on the silk surface in dot distribution, the dot diameter is 0.3mm, and the dot spacing is 0.5mm, and the silk surface with glue dots is covered on the sheepskin , at a temperature of 70°C and a pressure of 0.2kg / cm 2 , time 0.5 seconds overpressure on the roller press, the polyamide hot melt adhesive is assimilated after overpressure.

[0012] If the inhomogeneous dot gravure of polyurethane viscose resin is used to coat cowhide and cotton cloth, the overpressure temperature can reach 100°C and the pressure is 0.5kg / cm 2 , the time can reach 1 second, the point diameter of the bonding point can reach 0.5mm, and the distance between points can reach 0.8mm.

[0013] If it is a copolymer of 70% methacrylamide and 30% ammonium methacrylate, it is formulated into a glue solution containing 20% ​​water, and the pigskin and synthetic fiber fabrics are coated and compounded with uniform dot gravur...

Abstract

The invention relates to a silk leather facture. It is characterized in that it adopts the coat of the natural fiber, silk and compositive fiber and the leather and composes them physically. The compositive treatment is to flatten the natural fiber, the silk and the compositive fiber on the surface of the leather and agglutinate them point-to point. The invention is that the silk is flattening fixed on the leather surface, therefore it has enough physical intensity and solidity. The facture is simple, safe and non-pollution.

Description

technical field [0001] The invention relates to leather application technology. Background technique [0002] The use of leather has a long history. From the early human animal skins to keep out the cold, the research on leather has been step by step to meet the needs of society, and the manufacturing process has become more and more refined. For example, goat, sheep, cowhide, and pigskin are cut into several layers after dry cutting, which not only improves the utilization rate of the leather, but also provides a basic material guarantee for the lightness, thinness and softness of the leather body. In the process of leather processing, low alkali expansion, low-concentration enzyme softening at room temperature, treatment with non-polluting stabilizers, washing with detergents, leather fatliquoring and padding, and processes such as set grinding, breaking softening, and stretching boards have been adopted. The product reaches ultra-thin, light and soft, high-grade leather ...
