Abstract

Disclosed are a superfine fiber suede leather generating negative oxygen ion and a preparation method thereof. The superfine fiber suede leather generating negative oxygen ion comprises superfine fiber as a skeleton, polyurethane as an infilling, and a polycrystalline silicon carbide which is distributed in the polyurethane. In the natural environment, a negative oxygen ion concentration of 2000-20000 per cubic centimeter is generated around the leather, and the leather is prepared by dispersing the polycrystalline silicon carbide material into an impregnated polyurethane slurry, followed by impregnation, solidification, decrement and subsequent processing. The superfine fiber suede leather prepared by the technology can generate and release negative oxygen ions in the air and change the concentration of the negative oxygen ions around the leather, thereby improving the air quality in a certain range, and can be used in clothes, shoes, caps, bags and suitcases, sofas, cars, boats, aircraft cushions, interior decorations and the like, and is particularly suitable for relatively closed occasions.

Description

Technical field [0001] The invention relates to the field of superfine fiber synthetic leather, in particular to a superfine fiber suede leather capable of generating and releasing negative oxygen ions and a preparation method thereof. Background technique [0002] Microfiber synthetic leather is a composite material developed based on the soluble island-in-the-sea superfine fiber, composed of two parts: superfine fiber and polyurethane. Ultra-fine fibers have similar denier and structure to collagen fibers, so they have similar characteristics in terms of surface morphology and mechanical properties; the fiber bundles are made of polyurethane. Polyurethane is not simply filled in the leather body, but has many round shapes. , Needle-shaped microporous foaming structure, a three-dimensional network, forming a fine permeability structure, so that the leather body has a certain degree of air permeability and moisture permeability and compression elasticity. Microfiber synthetic le...
