Preparation method of high-elasticity hot air non-woven material with good restorability

The invention discloses a preparation method of a high-elasticity hot air non-woven material with good restorability. The preparation method comprises the steps of fiber opening, supporting, forming and web forming, fluffy shaping, reinforcing, cooling shaping and the like. The preparation method disclosed by the invention is simple in process and can be used for producing the hot air non-woven material with good bulkiness and high bulkiness rebound rate. Tests show that the high-elasticity hot air non-woven material prepared by the preparation method of the high-elasticity hot air non-woven material with good restorability has good bulkiness and high bulkiness rebound rate, can meet hot-pressing processing and ultrasonic processing at the same time, has relatively high restorability and rebound resilience, can keep a plump shape after being processed and formed, and the has the fluffy and breathable advantages and the like. 本发明公开了一种恢复性好的高弹性热风非织造材料的制备方法，包括纤维开松、支撑成型成网、蓬松定型、加固、冷却定型等步骤。本发明的制备方法工序简单却能生产良好蓬松性以及高蓬松
