Embodiment example

[0025] As a specific implementation example, a method for processing suede superfine fiber synthetic leather with higher scratch resistance and wear resistance is realized through the following steps:

[0026] 1) Island microfiber processing

[0027] Firstly, sea-island microfibers are produced by spinning sea-island component slices and island component slices according to a weight ratio of 1:1. The sea-component slices are polyethylene slices, and the island component slices are polyamide slices. The spinning production process includes spinning by mixed melt spinning or compound spinning, and the primary filaments are cooled and formed under the condition of a special air-conditioned ring blowing; in order to optimize the spinnability and physical properties of the filaments, the filaments are processed. Oil, and use the drafting effect of the drafting roller to improve the consistency of the polymer molecules inside the filament. At this time, the internal structure of the...

Abstract

The invention relates to a method for processing suede microfiber synthetic leather with high scratch resistance and high resistance. The method comprises the following steps: adding single-walled carbon nanotubes or multi-walled carbon nanotubes to nylon 6 (66) and polyethylene spinning solution, performing a solution blending process to prepare carbon nanotube / nylon 6 (66) / low density polyethylene composite system ultrafine fibers, coating the surface layer of an ultrafine fiber nonwoven fabric with a high-solid suede resin coating layer by a dry coating process, carrying out solvent volatilization to form dense and uniform resin cells in the surface layer of the nonwoven fabric, and performing impregnation, reduction and after-finishing processes to finally form the compact and uniformsuede ultrafine fiber synthetic leather with a low production cost and high physical properties.

Description

technical field [0001] The invention relates to the technical field of superfine fiber synthetic leather, in particular to a method for processing suede superfine fiber synthetic leather with high scratch resistance and abrasion resistance. Background technique [0002] Suede microfiber synthetic leather has a natural suede effect on the surface, which is widely used in artificial leather for footwear, bags, and clothing instead of natural suede. In the production of traditional suede superfine fiber synthetic leather, the suede resin mainly enters the superfine fiber non-woven fabric through wet impregnation, and then solidifies through wet method to replace DMF in the wet impregnation material to form cells, and then through The weight reduction process dissolves the sea component in the microfiber, dries and sets the shape, and forms a synthetic leather with a suede effect on the surface through the combination of skin grinding and dyeing and finishing processes. However,...
