▎ 摘  要

NOVELTY - A meltblown composite elastic nonwoven fabric comprises an external nonwoven fabric, a middle nonwoven fabric and an internal nonwoven fabric, which include 10-70 %mass high-fat polypropylene, 10-70 %mass low-fat polypropylene, 0.6 %mass emulsifying agent, 0.3 %mass wetting agent, 0.3 %mass spreading agent, 1 %mass antistatic agent, 0.2 %mass polyether silicone oil, 0.4 %mass graphene, 1 %mass color masterbatch, and remaining distilled water. USE - Meltblown composite elastic nonwoven fabric. ADVANTAGE - The meltblown composite elastic nonwoven fabric improves internal water absorption performance under the premise that the external waterproof performance does not reduce, and replaces the use of cotton cloth in some fields. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for processing of the meltblown composite elastic nonwoven fabric, which involves: (S100) separately mixing three nonwoven materials with different functional properties; (S200) melt-blowing the mixed material; (S300) rolling and cutting the formed nonwoven fabric; (S400) sticking an additive film; (S500) compounding three kinds of nonwoven fabrics; and (S600) detecting composite nonwoven fabric.
