SUPER-SOFT COMPOSITE WIPING NON-WOVEN FABRIC AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2023/000643

A1

A super-soft composite wiping non-woven fabric (14), which is of a layered structure. Melt-blown polyester fiber nets (12, 12') on two side surface layers of the soft composite wiping non-woven fabric (14) are composed of melt-blown polyester fibers with a fiber length of 10 mm-50 mm and a fiber length-diameter ratio of 1100-8000; a middle layer fiber net (13) is mainly composed of water-absorbing fibers; and fiber interlacing and interpenetrating areas are arranged between the two side surface layers and adjacent layers of the middle fiber layer. Compared with traditional polypropylene melt-blown fibers, the non-woven fabric has the advantages of polyester having higher rigidity, so that the polyester easily forms longer fibers, and the longer fibers are favorable for improving the hand feeling of the non-woven fabric, such that when used for wiping articles, the non-woven fabric is soft and comfortable when in contact with skin and is not liable to cause a skin allergy due to the stimulation of broken ends of the fibers.
