Eco-Friendly Insulation Materials with High Performance Sound Insulation Properties Using Recycled Cotton Fiber and their manufacturing methods.

摘要

The present invention collects, sorts, cuts, and separates different complex fibers from regenerated fiber 1 containing natural fibers, regenerated cotton fiber and regenerated hemp fiber, and regenerated fiber 2, including regenerated chemical fiber, LMPP (Low-Melting Polypropylene). Mixing, conveying, storing, conveying, burning, carding or airlaying, forming, needling, oven, pressing, cutting, and packaging processes as an automatic and continuous integrated process. A thickness of any one of 30mm, 50mm, 100mm, 150mm, and 200mm of various specifications, a width of any one of 300mm, 400mm, 600mm, 900mm, and 1,200mm, and a width of any one of 1800mm, 2,400mm, 3,000mm, 3,600mm manufactures products of length, In general, ureafoam, styrofoam (EPS), and polyurethane (Polyurethene) receive a strong impact, and the strength of cracking and bending is poor, so the restoring force is reduced, and moisture, water, mold, formaldehyde, and insect bites occur. and has a short service life, Since Gresswool contains harmful chemicals, which can cause itching and formaldehyde, As a substitute for ureafoam, styrofoam (EPS), polyurethane (Polyurethene), glass wool (Gresswool), and polyester (Polyester) It has an eco-friendly insulation material with high-performance soundproofing properties for soundproofing and insulating functions required for composite materials such as architecture, civil engineering, industry, transportation, shipbuilding, and aviation.
