Description

Novel leather product

Technical Field

The utility model belongs to the technical field of leather products, concretely relates to novel leather product.

Background

The traditional leather products refer to animal skins which are obtained by physical and chemical processing such as unhairing, tanning and the like and are denatured and not easy to rot. The leather is formed by tightly weaving natural protein fibers in a three-dimensional space, and the surface of the leather is provided with a special grain surface layer which has natural grains and luster and comfortable hand feeling.

With the change of times, people have changed their cognition ability on things, their receptivity to new things, and the like. In the 80, 90's of the 20 th century, people were primarily concerned with comfort, utility, and little fashion when purchasing apparel accessory products. People pursue popularity and fashion by the beginning of the 21 st century and pursue the shape-modifying property of the clothes. People pursue self feeling and dress accessories must embody self style and the like by the end of the 21 st century. However, this self style must be distinctive and personalized. Variability and batch production are contradictory, and the variability is more reflected in customized, small-volume production. Customization, miniaturization, is not feasible if still relying on conventional process conditions. Under the drive of the situation, novel equipment and emerging processes are produced at the same time, and the requirements of the times are met.
