Here is an introduction to pu coated fabric:

PU coated fabrics are unavoidable to talk about PU fabrics. PU fabrics are actually polyurethane. Its main performance is relatively abrasion resistance, solvent resistance and low temperature resistance (below -30 ℃), good waterproof and moisture permeability, wind resistance, softness and other characteristics. It is milky white emulsion under the general production situation. It can be combined into various fabrics or linings such as flat woven fabrics, knitted fabrics, and non-woven fabrics. Films with different characteristics can be made into two or two layers. The above processing compound.

The production of PU coated fabrics involves PU coating agent, which is a block polymer composed of two parts, the soft segment and the hard segment. The soft segment is to make the PU soft and elastic. It is mainly composed of polyether or polyester glycol. The size of its component will affect the softness and hardness of the PU coating; the hard segment is to make the PU coating have A certain strength and elastic modulus are mainly composed of various diisocyanates and chain extenders. The ratio of the soft segment and the hard segment and the types of raw materials can determine and affect the performance and use of the product.

There are many PU coating processing techniques: such as hot melt method, dry method, transfer method, bonding method, wet method, etc., of which the dry method is the most used one. The dry method is actually to pour the coating slurry into The container is then evenly coated on the base cloth with an applicator. After heating, the solvent or water will volatilize, and the PU coating will form a film on the surface of the fabric. The thin PU coating is the high-end dry direct coating. Products, mainly used for clothing fabrics.
