HOOK-AND-LOOP FASTENER FEMALE MATERIAL EXCELLENT IN PEELING STRENGTH AND ITS PRODUCTION

Japanese Patent JP3846979

B2

PROBLEM TO BE SOLVED: To obtain a hook-and-loop fastener female material free from the deterioration of an engaging force, even when repeatedly used for the engagement and disengagement with a male material, improved in operability and suitable for disposable commodities and the like by integrally laminating the specific second fiber layer to the surface of the first fiber layer comprising a thin fiber web.
SOLUTION: This hook-and-loop fastener female material is obtained by laminating the second fiber layer 3 to at least one surface of the first fiber layer 2 comprising a thin fiber web and subsequently jetting a high pressure columnar water flow to the laminate to integrate both the fiber layers. The second fiber layer 3 comprises a highly fuzzy, thermally fused non-woven fabric wherein small portions of a fiber group constituting the thermally fused non-woven fabric are broken and/or small portions of the fused portions between the adjacent fibers of the fiber group are peeled. Both the fiber layers 2, 3 are preferably integrated and subsequently thermally treated to shrink the first fiber layer 2, thus forming many short row-like projections 5 in the second fiber layer 3. A fiber layer containing thermally shrinkable fibers having the maximum thermal shrinkage degree of ≥50% in an amount of ≥30 wt.% is preferably used for the first fiber layer 2.
