Manufacturing method of soft fine-creased artificial super-fiber leather

Abstract

The invention relates to the technical field of super-fiber leather, in particular relates to a manufacturing method of a soft scabriculous artificial super-fiber leather. The invention provides a manufacturing method of a soft finely crinkled artificial super-fiber leather which is soft, fine in crease and has hand-feeling approaching to genuine leather. The manufacturing method comprises the following process steps in order: enabling non-woven fabric to pass through a soaking trough, dipping in a PU resin solution in a certain proportion, then coating a layer of PU resin solution, solidifying, washing and drying to obtain super-fiber rough blank; enabling the super-fiber rough blank to pass through a methylbenzene extraction production line, performing high-temperature decrement to manufacture super-fiber base cloth semi-finished product; and enabling the super-fiber base cloth semi-finished product to pass through a piece of super-fiber base cloth after-finishing line (oiling and drying, puffing and accurately grinding) to manufacture the super-fiber base cloth; enabling a piece of release paper to orderly pass through a first coating head, a second coating head and a third coating head, orderly coating a layer of shell fabric, a middle material layer and an adhesion layer on the surface of the release paler; pre-heating the release paper coated with the shell fabric, the middle material and the adhesion layer, and then combining the manufactured super-fiber base cloth with the release paper coated with the shell fabric and the backing material, drying through a drying oven, separating to obtain the semi-finished product; and performing surface genuine leather treatment on the surface of the semi-finished product to obtain the finished product.

Description

technical field [0001] The invention relates to the technical field of making superfibers, in particular to a method for making soft fine wrinkle imitation superfiber leather. Background technique [0002] Microfiber synthetic leather is a high-grade artificial leather that is composed of microfiber base cloth, adhesive layer and surface layer resin. There is no doubt that microfiber leather has many excellent properties, such as tensile strength, tearing, and peel strength. , acid and alkali resistance and other physical and chemical properties, etc. These physical properties are already higher than those of genuine leather. Automotive interiors, etc. But at the same time, it is undeniable that there is still a certain gap in the feel between microfiber and genuine leather. [0003] Especially compared with the first layer of leather, the softness and fineness of wrinkles are still relatively lacking, which also prevents microfiber from entering the market of high-end cas...

But at the same time, it is undeniable that there is still a certain gap in the feel between microfiber and genuine leather.

[0003] Especially compared with the first layer of leather, the softness and fineness of wrinkles are still relatively lacking, which also makes it impossible for microfiber to enter the market of high-end casual shoes, bags, etc.
