Problems solved by technology

[0006] 1. For ordinary veneered microfiber leather products, the thickness remains unchanged, and the texture is relatively regular, which is quite different from the leather texture;
[0007] 2. The thickness of embossed microfiber leather loses 0.1-0.3mm, the hand feels relatively stiff, and the softness of the finished product is poor;
[0008] 3. Generally, microfiber absorbing texture products feel relatively hard

Abstract

The invention discloses a preparation method of soft line-suction microfiber leather without thickness loss. The preparation method comprises following steps: S1, base fabric is subjected to softeningtreatment; S2, dry surface making is performed, and microfiber leather is obtained; S3, printing treatment is performed, and a printing layer is obtained; S4, a line-suction process is adopted, a vacuum line suction machine is utilized for sucking lines, a heating hood passes through two heating areas, the first heating area is used for heating a main body, the second heating area is used for supplementing heat, and cooling is performed; the soft line-suction microfiber leather without thickness loss is obtained. The thickness of the line-suction microfiber leather prepared with the method ofthe soft line-suction microfiber leather without thickness loss is increased by about 0.05 mm; the product which is 1.0 mm-1.5 mm touches soft and full; the lines are natural and are copied from genuine leather directly, a line-suction roller is made, the lines are transferred to the surface of the product by the line-suction roller, and the lines have a short development cycle and change fast compared with release paper.

Description

technical field [0001] The invention relates to the field of leather, in particular to a method for preparing thick and soft microfiber leather with absorbing patterns. Background technique [0002] There are different definitions of microfiber, also known as microfiber, fine denier fiber, ultrafine fiber, and the English name microfiber. Generally, fibers with a denier of 0.3 denier (5 microns in diameter) are called superfine fibers. Due to the extremely fineness of ultra-fine fibers, the stiffness of the silk is greatly reduced, and the fabric feels extremely soft. The fine fibers can also increase the layered structure of the silk, increase the specific surface area and capillary effect, and make the internal reflection of the fiber more delicate on the surface. , so that it has a silky elegant luster, and has good moisture absorption and moisture dissipation. Microfibers are a class of high-tech new fibers developed in modern times, among which sea-island microfibers ...
