Production method of TPU composite fabric
Production method of TPU composite fabric
The English name of composite fabric is: “LaminationFabric” and “SoftShellFabric”. TPU composite fabric and PTFE composite fabric are a new type of material formed by bonding one or more layers of textile materials, non-woven materials and other functional materials. TPU composite fabrics and PTFE composite fabrics are divided into ordinary composite fabrics (made by bonding fabrics and linings with adhesives to improve the fabric texture, suitable for process simplification and large-scale production of clothing processing) and functional composite fabrics (composited The fabric has special functions such as waterproof, moisture permeable, radiation resistance, washing resistance, and wear resistance).
There are two ways to make TPU composite fabrics. One is called post-pasting: first make a TPU film and then glue it with the fabric. The other is called online lamination: apply glue on the fabric or not glue it, and directly put the TPU on it. The fabric is made of TPU composite fabric or mesh fabric.
TPU composite fabric is to use TPU film on various fabrics to form a composite material, and combine the characteristics of the two to obtain a new type of fabric. TPU (Thermoplastic polyurethanes), thermoplastic polyurethane, is a linear block copolymer composed of oligomer polyol soft segments and diisocyanate-chain extender hard segments. TPU can be cast, blown, calendered or coated to make a film. It has the advantages of good elasticity, strength, wear resistance, good cold resistance, environmental protection and non-toxic properties.
Generally, the factories that do post-pasting processing are not large in scale. There are many small factories in China. The post-pasting process requires the TPU film to be subjected to high temperature and high pressure again. Improper process control will cause damage to the film and even small holes.
The uses of TPU composite fabrics include: inflatable life jackets, diving BC jackets, life rafts, inflatable boats, inflatable tents, military inflatable self-expanding mattresses, massage air bags, medical anti-decubitus mattresses and professional waterproof backpacks.
The width of TPU composite fabric is limited to the size before the two fabrics are combined, which can generally reach 145CM. If it is a composite of knitted fabrics, it can be wider. There are several types of composites: woven fabrics and knitted fabrics; knitted fabrics and knitted fabrics; woven fabrics and woven fabrics. Sports and leisure clothing uses knitted fabric and composite knitted fabric, which has the effect of woven fabric and good elasticity. Therefore, in the eyes of consumers of this type of clothing, it is still relatively popular and loved by the public.
TPU composite fabric uses
Online lamination is to laminate the fluid TPU film on the fabric at one time, which avoids damage to the film. The surface is beautiful and can be made with different textures. However, this composite method requires large equipment investment and high technical requirements. There are very few domestic manufacturers that can achieve this kind of composite process, and currently only a few have mature equipment and technology. In fact, it was introduced from Taiwan and then improved. Currently, it is a domestic manufacturer specializing in inflatable life jackets, medical inflatable products, and massage air bag fabrics.
TPU composite fabrics are used for: inflatable life jackets, diving BC jackets, life rafts, inflatable boats, inflatable tents, military inflatable self-expanding mattresses, massage air bags, medical anti-decubitus mattresses and professional waterproof backpacks. wgAe9c7
