NONWOVEN FABRIC FOR HOOK-AND-LOOP FASTENER AND ITS PRODUCTION

Japanese Patent JP3580626

B2

PROBLEM TO BE SOLVED: To obtain a nonwoven fabric for hook-and-loop fastener, constituting a female material of the hook-and-loop fastener so as to be made of the nonwoven fabric, capable of joining a male material of the hook-and-loop fastener to an arbitrary part of the surface of the nonwoven fabric, functioning as the hook-and-loop fastener by only fixing the male material to a specific part of joining target for fitting the male material and capable of properly corresponding to used object.
SOLUTION: A filament nonwoven web layer is formed of divided type conjugate filaments and the filament nonwoven web layer and a staple nonwoven web layer are laminated to form a laminated nonwoven web. Then, the laminated nonwoven web is placed on a moving porous supporting plate having 10-20 mesh to apply pressure liquid flow treatment to the laminated nonwoven web and a constituent fiber of the filament nonwoven web layer and a constituent fiber of a staple nonwoven web layer are mutually three-dimensionally interlaced and mutual constituent fibers of the staple nonwoven web layer are three-dimensionally interlaced and holes having 0.5-3.0mm2 area are provided so as to have 15-60 numbers/cm2 arranging density in the laminated nonwoven web to provide the objective nonwoven fabric for hook-and-loop fasteners.
