Leather knowledge analysis: The characteristics of washed leather and the difference between genuine leather and pure leather

Washed leather is a retro PU leather that was popular two years ago. Scrape a layer of water-based paint on the PU leather, then add acid and wash it with water to damage the structure of the surface coating, causing the raised areas on the surface to fade and show the base color, while the concave areas retain the original color. No matter what vintage washed leather is, it will fade even if it is not washed for a long time, just more or less.

Especially when washing, do not use laundry detergent. You can choose a neutral shampoo or shower gel, and the shorter the washing time, the better. This can reduce fading. The anti genuine washed leather that appeared in the market last year was directly washed to make it soft and smooth, without acid washing. This type of washed leather will not fade. After washing, it is best to apply a layer of leather protector to make it soft and shiny as new.

Differentiation between pure leather, genuine leather, and washed leather

Pure leather. After labeling the product with pure leather, it is basically possible to determine whether the material is sheepskin, pigskin, or cowhide. However, the grade of pure leather is also divided. Firstly, in terms of category, the cost of pigskin clothing is the lowest, and among sheepskins, the price of sheepskin is higher than that of goat skin. Secondly, pure leather materials are divided into first layer leather and second layer leather during processing, with higher prices and better quality for the first layer leather.

There are significant differences between the first layer of cowhide and the second layer of cowhide in terms of appearance, texture, physical and chemical properties, organizational structure, appearance, comfort, service life, price, quality, and other aspects.
Differentiation method: The scalp layer has clear three layers of texture, namely the staining layer, nipple layer, and fiber layer. The others only have two layers.

Genuine leather. Conceptually speaking, genuine leather is a common term used by people to distinguish between synthetic leather and natural leather. In the concept of consumers, there are actually many types of genuine leather, with varying qualities and prices, so genuine leather is a vague term in the commodity market. In a commonly used process, the leather that is crushed, then added with adhesive, and then molded into shape is also commonly referred to as genuine leather. The natural cost of clothing processed with this type of synthetic leather is much lower.

Differentiation method: The surface of synthetic leather has no pores, while the surface of the leather is wet. Blow air from the other side, and the synthetic leather has no bubbles.

Washed leather, microfiber leather, environmentally friendly leather. Clothes made of materials such as washed leather, microfiber leather, or eco-friendly leather have a similar appearance to genuine leather clothing, but are usually made by pressing and laminating PVC with plasticizers and other additives onto the fabric. Compared to pure leather or genuine leather clothing, this type of leather clothing is cheap, colorful, and has a variety of patterns, but it is easy to become hard and brittle.

Distinguishing method: When inspecting from the edge stitching, the artificial leather substrate has cotton gauze, and there are small sponge like tissues in the cortex.
