Problems solved by technology

[0002] At present, with the solvent-based polyurethane composite adhesives supplied in the market, if the composite textiles are printed again, the paste dots will shift and cause foaming, resulting in an increase in waste products.
[0003] The bedding products exported to the European Union must be washed 60 times at 90°C without foaming. None of the products currently on the market can meet this requirement.
