Nonwoven loop member for a mechanical fastener

The loop component for mechanical fasteners is equipped with a nonwoven fabric web, and a nonwoven fabric web has a pattern of the crossing joint line. As for the pattern, at least one copy is characterized by each continuation joint line by which the first plurality does not cross including the continuation joint line by which the continuation joint line of the first plurality by which it does not cross, and the second plurality do not cross intersecting each continuation joint line of the second plurality by which it does not cross. The crossing joint line demarcates an uncombined pattern element, and each of a pattern element can appoint a boundary partially at least by nonlinear classification of a joint line. The joint pattern for nonwoven fabric webs is suitable to use it as a loop component of a mechanical fastener. A joint pattern contains the crossing joint line which has uniform width and demarcates some joint pattern elements per unit area, At least one of the joint lines is nonlinear, and the ratio of the outline to a total joint area of a joint pattern becomes larger than the joint pattern which has the same uniform line width and demarcates the joint pattern element of the same number per unit area and which consists of straight lines altogether.
