Release Time: 2020-05-14

Summary: Perhaps many people don't know that composite fabrics have become deeply integrated into all aspects of our lives. Composite fabrics have significantly improved performance compared to traditional fabrics, not only in terms of materials and patterns, but also in practicality. Without mentioning professional applications, take ski and climbing suits for example; these fully utilize and showcase the performance of composite fabrics. But besides these, do you know of any other applications of composite fabrics?

I. Performance Development

In daily life, many people may not realize that composite fabrics have become deeply integrated into various aspects of our lives. Composite fabrics have significantly improved performance compared to traditional fabrics, not only in terms of material and patterns, but also in practicality. Without mentioning professional applications, consider ski and climbing suits; these fully utilize and showcase the performance of composite fabrics. But beyond these examples, what other applications of composite fabrics are you aware of? (Crosslinking agent used in PVC composite fabric)

With the continuous improvement of people's living standards, lifestyles are constantly changing. Many people now place great emphasis on health, seeking medical attention even for minor ailments. Hospitals, therefore, are places with a diverse population and a high concentration of bacteria. This necessitates bedsheets that are antibacterial, dust mite-resistant, and environmentally friendly to promote patient health and recovery. This need extends beyond hospitals to hotels as well, making composite fabrics widely used in these settings. Furthermore, mothers today prioritize the use of baby diapers that are waterproof, breathable, absorbent, quick-drying, antibacterial, and soft, ensuring baby's safety and comfort. The widespread use in these areas highlights the potential of composite fabrics in performance development. (Crosslinking agent used in PVC composite fabric)

II. Identification Methods

1. Feel: Touch the surface of the leather. A smooth, soft, full, and elastic feel indicates genuine leather; while artificial synthetic leather generally feels rough, stiff, and lacks softness. (Crosslinking agent used in PVC composite fabric)

2. Visual Inspection: Observe the leather surface for clear pores and patterns. Cowhide has relatively uniform fine pores, yak hide has coarser and sparser pores, goatskin has fish-scale-like pores, and pigskin has triangular coarse pores. Artificial leather, while imitating pores, lacks clarity. (Crosslinking agent used in PVC composite fabric)

Below is an introduction to the characteristics and identification methods of pigskin, horsehide, cowhide, and sheepskin: Cowhide has a fine surface, high strength, and is suitable for making shoes; sheepskin is light, thin, and soft, making it an ideal material for leather clothing; pigskin has good breathability and moisture permeability, making it suitable for making underwear and children's products; horsehide has a tighter fiber structure and higher strength, making it suitable for making trousers and boots.

Generally, the size, density, and distribution of pores on the leather surface are the main criteria for distinguishing cowhide, pigskin, horsehide, and sheepskin. Pigskin: The pores on the surface are round and large, extending obliquely into the leather. The pores are arranged in groups of three, creating small triangular patterns on the leather surface. Cowhide: Both yellow cowhide and water buffalo hide are called cowhide, but there are some differences. The pores on the surface of yellow cowhide are round and extend relatively straight into the leather. The pores are dense and uniform, arranged irregularly, like stars in the sky. The pores on the surface of water buffalo hide are larger than those of yellow cowhide, and the number of pores is less than that of yellow cowhide. The leather is looser and less refined than yellow cowhide. Horsehide: The pores on the surface are oval, slightly larger than those of yellow cowhide, and arranged more regularly. Sheepskin: The pores on the grain surface are flat and round, clear, and arranged in groups of several, forming a fish-scale pattern. (Crosslinking agent used in PVC composite fabric)

3. Smell: Genuine leather has a characteristic leather smell; while artificial leather has a strong plastic odor. (Crosslinking agent used in PVC composite fabric)

4. Burning Test: Tear off a small fiber from the back of the leather and artificial leather and ignite it. A pungent smell and the formation of hard beads indicate artificial leather; a hair-like smell and no hard beads indicate genuine leather. (Crosslinking agent used in PVC composite fabric)
