Abstract

The present ivnention relates to a high-strength ultrafine fibre imitation leather. It is made up by using sea-island ultrafine fibre base cloth through processes of impregnating with polyurethane, extracting treatment and after-finishing. The described base cloth is a double-layer or more than double-layer composite base cloth formed from sea-island composite fibre woven fabric and non-woven fabric which are combined together by means of needling process or cohesive process, then said invention makes the composite base cloth undergo the processes of impregnating with polyurethane, hardening, extracting 'sea' component in the solvent capable of removing 'sea' component from sea-island fibre to obtain semifinished product, widening forming, mellowing, dyeing, grinding or sticking film so as to obtain the invented product.

Description

Technical field:

[0001] The invention relates to simulated composite leather and a manufacturing method thereof, in particular to a high-strength superfine fiber simulated composite leather containing a composite layer and a manufacturing method thereof. Background technique:

[0002] As a substitute for natural leather—synthetic leather is gradually recognized by consumers due to its good appearance consistency, maintenance-free, and easy cutting, but its development is affected by its poor air permeability and moisture permeability. In recent years, due to the invention of sea-island superfine fibers, and the fiber fineness of sea-island superfine fibers is below 0.01 denier, the synthetic leather made of sea-island superfine fiber non-woven fabrics resembles natural leather. Soft and smooth, beautiful surface, air permeability, moisture permeability, strength, and service life are almost comparable to natural leather, especially bright colors, uniform texture, anti-moth, ...
