一种组合铺网水刺无纺布及其制备方法
By combining direct web laying and air-laid web laying technologies, crimped hydrophobic fibers and ultrafine cellulose fibers are combined with low-melting-point fibers to form a three-layer composite fiber web. This solves the problems of small difference in longitudinal and transverse strength and rapid water absorption in nonwoven fabrics used in wiping products, achieving wear resistance, durability and high-efficiency production.

Abstract
本发明涉及一种组合铺网水刺无纺布，由三层层叠复合纤维网经水刺加固形成，所述三层层叠复合纤维网由第一表层、第二表层以及位于第一表层和第二表层之间的中间层构成；所述第一表层和第二表层为卷曲疏水纤维层，通过直接铺网形成；所述中间层为亲水纤维层，通过气流成网形成；所述第一表层与第二表层的MD方向基本垂直；所述卷曲疏水纤维的卷曲度为7‑10，卷曲率为15％‑20％；所述亲水纤维层采用结晶度为40‑60％的超细纤维素纤维与低熔点纤维复合制成，超细纤维素纤维的质量占比为80‑95％。本发明的制备过程不涉及化学改性和后整理工序，工艺便捷；制得的无纺布吸水性好、纵横强力差小、耐磨耐用，适用于擦拭用品。
