Description
1. Technical field
[0001] The invention belongs to the technical field of non-woven fabrics. 2. Background technology
[0002] The existing foam uses polyurethane as a raw material, so it has the disadvantages of toxicity, flammability, poor elasticity, poor warmth retention, easy aging, and short service life (only about 2 years). The existing spray-bonded cotton uses polyester (PET) fibers as raw materials, and its technological process is to send general polyester fibers to the cotton feeding machine after being opened by a bale opener, a cotton opener, and then carded into a thin film by a carding machine. Layered, that is, the fibers are two-dimensionally distributed, and then the two-dimensionally distributed thin-layered polyester fiber layer is folded into the required thickness with a molding machine, sprayed with adhesive, so that the layers of fibers are combined, dried and dried become. Because the fibers of the glued cotton are distributed in two dimensions, i...
