What Is The Material Of Pu Fabric?
When we buy leather products, we often hear a very professional word, it is PU fabric, in fact, this material can be seen in many products in our daily life, such as the clothes we wear, The products that are usually used in thermal insulation materials are all made of it. But many friends are not particularly clear about the material of PU because they have not been exposed to this knowledge, so let's take a look at the specific material of the fabric PU.
1. What is the material of the fabric PU?
PU fabric is a kind of anti-leather fabric, PU is the abbreviation of English polyurethane, its chemical Chinese name is "polyurethane", and it is a kind of polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth-largest plastic", and is widely used in many fields of the national economy because of its excellent performance.
2. What are the characteristics of PU fabrics?
（1）The PU fabric has good physical properties and is resistant to torsion, has good softness, high tensile strength, and is breathable. The pattern of the PU fabric is to use a pattern paper to heat and press the leather surface of the semi-finished product first, wait for it to cool down, and then separate the paper leather for surface treatment.
（2）The air permeability is relatively high, the temperature permeability can reach 8000-14000g/24h/cm2, the peeling strength is high, and the water pressure resistance is high. It is an ideal material for the surface layer and bottom layer of waterproof and breathable clothing fabrics.
（3）The price of PU fabrics is relatively high, and the price of PU fabrics with special requirements is 2-3 times higher than that of PVC fabrics. The pattern paper required for general PU fabrics can only be used 4-5 times, which is basically scrapped.
3. How to choose PU fabrics?
（1）First of all, look at the touch, touch two fabrics at the same time with your hands, the surface of a good leather fabric will have a very soft and elastic feeling, while the contact of a poor fabric is no different from directly touching the desktop, and it will feel similar to the touch. Plastic feel.
（2）Use a scraper or a car key to scratch the surface of the two pieces of fabric many times. The good fabric will basically not leave any traces, and it is very wear-resistant and scratch-resistant. Poor fabrics leave marks after a few scratches, and the surface has already begun to wear.
（3）You can also knead the two pieces of fabric into a ball by hand, and watch the two pieces of fabric return to a flat state. Good fabrics will recover quickly and there will be no traces of kneading, while poor fabrics will be Very clear kneading marks are seen on the surface, and wrinkles are also seen.
