Abstract
A male component of a male and female fastening system, such as a hook and loop fastener, that can remain fastened to a female component under high levels of shear force. The male component has a backing material with projections extending from the backing material at an angle toward the direction of fastener force. The combination of the male component with a standard female loop component results in a secure fastening system. The combination of the male component with a standard female loop component is particularly beneficial when used in absorbent articles.
Claims15
A male and female fastening system comprising a male component and a female component;
- the female component including a loop backing and a plurality of loops protruding from it;
- the male component including a hook backing and a plurality of projections protruding from the hook backing, each projection having a first longitudinal surface portion consisting essentially of a first polymer and a second longitudinal surface portion adjacent the first longitudinal surface portion and including a second polymer.
A method of making a male component of a male and female fastening system, comprising the steps of:
- heating at least two polymers, each of which shrink to a different extent when cooled;
- transferring the heated polymers to a mold;
- cooling the polymers;
- and
- removing the cooled polymers from the mold;
- wherein the cooling causes the polymers to set in a shape of a plurality of projections protruding from a plane at an angle relative to the plane.
