The soft feel and hardness of sandwich mesh can be adjusted after treatment. Is it better to be soft or stiff? This depends on the requirements of each product. For example, the sandwich mesh used in the interlayer of clothing must be stiff to make the clothes neat. Mattresses, urine mats and sandwich mesh for infant products need to be softer if they are in direct contact with the skin. The softness can also be adjusted with softener. The fabric with softener is soft and smooth. Sandwich mesh manufacturers recommend not to use it. The baby's skin is sensitive and delicate. No matter what kind of softener, there are chemical agents in it. There can be no harm.
