Title:
MESH-LIKE HOOK FASTENER AND DYEING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/235613
Kind Code:
A1
Abstract:
Provided is a mesh-like hook fastener that: has a substrate sheet and a large number of hook-shaped engaging elements rising up from said substrate sheet; is dyed uniformly without any dyeing speck; is less likely to undergo breaking of the hook-shaped engaging elements or the substrate sheet as a result of engagements and detachments, or damage to a loop fastener of an engaging mate; and exhibits superior shape conformability and flexibility. This mesh-like hook fastener is configured such that the substrate sheet (A) comprises a linear-portion group layer (A1) which is formed with a plurality of linear portions (a1) that are arranged parallel to each other at intervals on the same plane, and a shape-retaining-lug-row group layer (A2) which is formed with a plurality of shape-retaining lug rows (a2) that rise from the rear surface of said linear-portion group layer so as to be arranged parallel to each other at intervals, the linear-portion group layer (a1) and the shape-retaining lug rows (a2) intersecting with each other and being formed integrally at the respective intersections. The substrate sheet (A) and the hook-shaped engaging elements (B) are each composed of a thermoplastic elastomer resin and are also dyed with a stain.
