PU leather is an abbreviation for polyurethane in English, and the chemical name in Chinese is "polyurethane". PU leather is a skin composed of polyurethane. Widely used in luggage, clothing, shoes, vehicles, and furniture decoration, it has been recognized by the market, with a wide coverage, large quantity, and a variety of varieties, which traditional natural leather cannot meet. PU leather has good and bad quality, and good PU leather is more expensive than genuine leather, with good shaping effect and bright surface!

What is the maintenance method for PU leather?

Cleaning method for PU leather:

1. Do not wash with water or detergent, wipe gasoline

2. Do not dry clean

3. Can only be washed with water, and the washing temperature should not exceed 40 degrees Celsius

4. Do not expose to sunlight

Unable to come into contact with some organic solvents.

6. PU leather jacket requires a set bag, so it cannot be folded

Natural leather has natural characteristics, so it is widely used to produce daily necessities and industrial products. However, with the increase of World population, human demand for leather has doubled, and a limited number of natural leather can no longer meet this demand. In order to solve this contradiction, scientists began researching and developing artificial leather and synthetic leather decades ago to make up for the shortcomings of natural leather. The research history of over 50 years is the process of artificial leather and synthetic leather challenging natural leather.

Scientists started from studying and analyzing the chemical composition and organizational structure of natural leather. From Nitrocellulose linoleum to PVC artificial leather, it is a generation product of artificial leather. On this basis, scientists have made various improvements and explorations, first in terms of equipment, and secondly in terms of coating resin modification and improvement. In the 1970s, Synthetic fiber nonwovens appeared processes such as needle binding and mesh bonding. The substrate has lotus root cross section and hollow fiber, reaching a porous structure, which conforms to the mesh structure of natural leather. At that time, the surface of synthetic leather was already a fine tool group polyurethane layer, which could rival the particle surface of natural leather. Therefore, the appearance and internal structure of PU synthetic leather gradually approached that of natural leather, and other physical properties approached the indicators of natural leather, with a brighter color than natural leather. At room temperature, folding can exceed 1 million times, and at low temperature, folding can also reach the level of natural leather.

The emergence of ultrafine PU synthetic leather is the third generation of artificial leather. The non-woven fabric with three-dimensional structural mesh creates conditions for synthetic leather to surpass natural leather in equipment. This product combines the newly developed PU plate impregnation and composite layer processing technology with perforated structure, giving full play to the huge surface area and strong absorption of Microfiber, so that the superfine PU synthetic leather has the inherent moisture absorption characteristics of fast superfine collagen fiber natural leather, so it can be comparable to natural leather in terms of internal microstructure, appearance texture, physical characteristics, wearing comfort, etc. In addition, Microfiber synthetic leather is superior to natural leather in chemical resistance, quality uniformity, mass production and processing adaptability, water resistance and fungal degeneration. The various properties of synthetic leather have been proven to be irreplaceable by natural leather. Based on market analysis both domestically and internationally, synthetic leather has also extensively replaced scarce natural resources.
