Embodiment 1

[0040] (1) Blend the polyethylene of the "sea" component and the polyester of the "island" component at a weight ratio of 20%:80%, and spin it into sea-island short fibers of 0.1-5 denier;

[0041](2) Sea-island staple fibers are spun into 10S yarns by spinning technology, dyed, then warped and slashed, and then woven into a plain weave single-color base cloth with a thickness of 0.04mm;

[0042] (3) impregnating the base cloth with a colored polyurethane impregnating solution with a concentration of 30%, then coagulating with a coagulant, rolling and scraping the surface to obtain a semi-finished synthetic leather product;

[0043] (4) Use 86°C hot toluene to dissolve the semi-finished synthetic leather to remove the "sea" component in the sea-island superfine fiber, and then wash and dry it with water to obtain a monofilament fineness of 0.01-0.0005 denier, and the inter-fiber Microfiber woven cloth synthetic leather with voids;

[0044] (5) The microfiber woven cloth synth...

Embodiment 2

[0045] (1) The "sea" component polyethylene and the "island" component polyamide are blended at a weight ratio of 40%:60%, and are spun into colored 0.1-5 deniers with the masterbatch in the spinning process Sea-island staple fibers;

[0046] (2) Use the spinning technology to spin the colored island-in-the-sea short fiber into 16S yarn, then warp and sizing, and then weave it with conductive fiber to form a twill single-color base fabric with a thickness of 0.07mm on the surface;

[0047] (3) After impregnating the base cloth with a colored polyurethane impregnating solution with a concentration of 20%, then coagulating with a coagulant, rolling and scraping the surface to obtain a semi-finished synthetic leather product;

[0048] (4) Use 80°C hot toluene to dissolve the semi-finished synthetic leather to remove the "sea" component in the sea-island superfine fiber, and then wash and dry it with water to obtain a monofilament fineness of 0.01-0.0005 denier, and the inter-fibe...

Embodiment 3

[0051] (1) Blending the "sea" component polyethylene and the "island" component polyester at a weight ratio of 30%:70%, and spinning them into sea-island short fibers of 0.1-5 denier;

[0052] (2) The island-in-the-sea staple fiber is spun into 6S yarn by spinning technology. After dyeing, it is warped and slashed, and then weaved into a layer of yarn spun from the island-in-the-sea staple fiber, and the other layer is a non-island-in-the-sea superfiber yarn. Fine fiber, the surface is jacquard pattern multi-color two-layer base fabric with a thickness of 0.02mm, and the layers are combined through the weaving process;

[0053] (3) After impregnating the base cloth with a colored polyurethane impregnating solution with a concentration of 15%, then coagulating with a coagulant, rolling and scraping the surface to obtain a semi-finished synthetic leather product;

[0054] (4) Use 83°C hot toluene to dissolve the semi-finished synthetic leather to remove the "sea" component in th...

Abstract

The invention relates to superfine fibre synthetic leather and the technical field of synthetic leather base cloth, in particular to superfine fibre synthetic leather with a superfine fibre weaving cloth as base cloth and a manufacturing method thereof. The invention takes island-typed superfine fibre weaving cloth as base cloth, the thickness of the fabricated superfine fibre weaving cloth synthetic leather is 0.05-2.0mm, the surface of which is provided with patterns of different shapes such as tabby or twill or jacquard weave or gingham or suede or film surface, the color is single or multiple, the leather has one or two or more layers which are combined by the weaving technology. The superfine fibre synthetic leather of the invention is comfortable to wear and cost-effective, thus being more suitable for manufacturing thin clothes or decorative cloth and the like.

Description

technical field [0001] The invention relates to the technical field of superfine fiber synthetic leather and synthetic leather base cloth, in particular to a superfine fiber synthetic leather with superfine fiber woven cloth as the base cloth and a manufacturing method thereof. Background technique [0002] At present, microfiber synthetic leather is used as a high-simulation artificial leather, simulating the structure of natural leather, using the blending method to make "sea island" fibers, and using "sea island" fibers to make high-density non-woven fabrics with a three-dimensional network structure, with high performance , low modulus, and open-cell water-based polyurethane are filled, and then extracted and separated into bundles of microfibers as the matrix of high-simulation leather with simulation performance. The fiber fineness can reach below 0.01 denier. Microfiber high imitation leather has played a role in the huge surface area and strong water absorption of u...
