One is called post-pasting: it is first made into TPU film and then glued to the fabric. Use PUR hot-melt adhesive process to make it fit firmly, not easy to delamination, environmentally friendly and tasteless, waterproof and breathable, anti-cold and keep warm, washable, etc. But because the TPU film needs to be re-applied with high temperature and high pressure during the post-pasting process, improper process control will cause damage to the film and even small holes. Therefore, it is necessary to have a rich compound experience and strictly control each process to achieve stable quality. It is mainly used for Home-textile with waterproof and breathable features, like mattress protectors, baby products, dry sheets, blackout curtains, etc.
The other is called online compounding: apply glue or no glue on the fabric, and directly compound the fluid TPU film on the fabric at one time to make a TPU composite fabric or mesh cloth, which avoids damage to the film. The shape is beautiful, and different textures can be made. However, this composite method requires large equipment investment and high technical requirements. There are very few domestic manufacturers that can achieve this composite process, and currently only a few have mature equipment and technology in China. At present, it provides high-quality products such as inflatable life jackets, diving BC jackets, life rafts, inflatable boats, inflatable tents, military inflatable self-inflating mattresses, massage airbags, medical anti-decubitus mattresses, and professional waterproof backpacks for the most professional in China.
