Crimping fiber elastic non-woven fabric and manufacturing method thereof

The invention discloses crimping fiber elastic non-woven fabric and a manufacturing method thereof. The cross section of each crimpled fiber contains two thermoplastic raw materials with different melting points, the two thermoplastic raw materials refer to polyisoprene and polyethylene, and the melting point deviation exceeds 100 DEG C. The two raw materials are distributed in the cross section direction according to a parallel structure or an eccentric core sheath structure or an orange section structure. A melt spinning tubular drafting technology is adopted, and in the fiber spinning process, for the reason that the heat shrinkable properties of the two raw materials are different, the fibers can be twisted in the cooling process. In the cooling drafting process, a high-speed rotating electrode is used for enabling a drafting tube with a thread structure to be rotated, the fibers are further driven to rotate, and accordingly high crimpiness fibers can be obtained. After the fibers are laid to form a net, the fibers are solidified to form the non-woven fabric through a needle-punched or hydroentangled technology. The crimping fiber elastic non-woven fabric has excellent elasticity and can be widely applied to the fields of medical treatment, sanitation, clothing, industry and the like.
