Problems solved by technology

[0002] Most of the existing non-woven fabrics are made of single polyester staple fiber through acupuncture or spunlace. Due to the characteristics of polyester staple fiber, the elongation rate of the product is relatively large, so the scope of use of the product is limited to a certain extent.
For products with certain requirements on hardness, elasticity, tensile strength, wear resistance, etc., such as Simmons mattresses, it is difficult to adapt to ordinary non-woven fabrics made of single polyester staple fiber through acupuncture or spunlace. Most of the existing Simmons mattresses use wood boards. Due to the limited wood resources and the use of formaldehyde in the processing of wood boards, excessive formaldehyde content will cause great harm to the human body and the environment; another example is the backup of automotive interior parts. In the past, phenolic resin was added to the non-woven fabric for the base material of the box and the central carpet. Because the material contains a large amount of formaldehyde, it leads to a large amount of free formaldehyde in the car. The formaldehyde content in the air in the car exceeds the standard, which not only pollutes the environment, and endanger human health
