Method for manufacturing silk leather

Abstract

The invention discloses a method for manufacturing silk leather. A technical scheme of the invention is by conducting physical combined treatment on natural fiber, silk, synthetic fiber fabric and genuine leather; the combined treatment is by horizontally placing natural fiber, silk and synthetic fiber fabric on the leather surface, and conducting point bonding; and the point bonding is by bonding the adhesion points in point distribution on the combined surface. The point bonding involves points in uniform distribution or non-uniform distribution. The above natural leather is sheepskin, goat skin or pigskin. Especially the physical combined treatment of the invention refers to: coating with gravure screen printing, printing the adhesive resin or thermoplastic resin on the fabric, then horizontally arranging on the leather surface, conducting overvoltage processing by hot rolling or sheet rolling under the temperature of 80-100 DEG C and pressure of not less than 0.2 kg / cm<2> for 0.5-2 s. The point bonding point can be evenly distributed in diameter of 0.3-0.5 mm and point distance of 0.5-0.8 mm, and can also be in nonuniform distribution with the same point diameter and different distance between the similar points.

Description

technical field [0001] The invention specifically relates to a method for making silk leather. One application technology of leather. 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 split into several layers after dry splitting, which not only improves the utilization rate of the leather, but also provides a basic material guarantee for the light, thin, and soft 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 ultr...

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. Thinner and worse, like making leather into underwear, it is not as safe, hygienic, comfortable and healthy as cotton and silk when worn on the body
