Abstract
Described herein is a male fastener strip having a multitude of hooking elements on one side of substrate cloth, which is characterized in that the individual hooking elements are spaced from adjacent hooking elements by X(mm) and Y(mm) in the transverse and longitudinal directions of the fastener strip, respectively, such that X is between 2.0 and 4.0 mm, inclusive and X/Y is in the range of 0.5 to 3.5.
Claims15
A male fastener strip:
- (a) having a multitude of hooking elements on one side of a substrate cloth woven from nylon or polyester yarn;
- (b) possessing the capability of repeated engagements of interlocking and unlocking to a female fastener strip having loop elements;
- (c) said hooking elements being formed by a weaving process on one side of said substrate cloth;
- and
- (d) said hooking elements being spaced from adjacent hooking elements by X(mm) and Y(mm) in the transverse and longitudinal directions of said substrate cloth, respectively, such that the value of X is between 2.7-2.9 mm, inclusive, and the ratio X/Y is between 0.9-1.6, inclusive, whereby:
- (e) directional variations of the coupling force when engaged face-to-face with a female fastener strip are small and
- (f) the male fastener strip is soft in texture.
