Refastenable garment attachment means with low impact on the garment

Abstract

A male component of a mechanical 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 protrusions extending from the backing material at an angle toward the direction of fastener force. The combination of the male component with a female loop component results in a secure fastening system.

       6 . The mechanical fastening system of  claim 1 , wherein at least a portion of the plurality of the protrusions extend from the backing material of the male component at an angle substantially perpendicular to the backing material of the male component.  
   
   
       7 . The mechanical fastening system of  claim 1 , wherein at least a portion of the plurality of protrusions extend from the backing material of the male component at an angle α of about 15 degrees to about 85 degrees relative to the backing material of the male component.  
   
   
       8 . An absorbent article comprising the mechanical fastening system of  claim 1 .  
   
   
       9 . The absorbent article of  claim 8 , wherein the absorbent article is selected from the group consisting essentially of: a diaper; a training pant; a feminine hygiene product; an incontinence product; a wound care product; and, medical garment.  
   
   
       10 . A mechanical fastening system comprising: 
 a male component wherein the male component comprises a backing material and a plurality of first protrusions and a plurality of second protrusions extending from the backing material; and,    a female component capable of engaging the male component; wherein the plurality of first protrusions extend from the backing material of the male component at an angle α of about 5 degrees to about 85 degrees relative to the backing material of the male component and the plurality of second protrusions extend from the backing material of the male component at an angle α of about 95 degrees to about 175 degrees relative to the backing material of the male component.    
   
   
       11 . The mechanical fastening system of  claim 10 , wherein the female component further comprises material selected from the group consisting essentially of: textile fabric; knitted textile fabric; non-woven web; and, combinations thereof.  
   
   
       12 . The mechanical fastening system of  claim 10 , wherein the female component further comprises a loop backing material consisting of a plurality of loops or fibers extending from the loop backing material.  
   
   
       13 . The mechanical fastening system of  claim 10 , wherein at least a portion of the plurality of the first protrusions are shorter than at least a portion of the plurality of the second protrusions.  
   
   
       14 . The mechanical fastening system of  claim 13 , wherein the shorter first protrusions are from about 5% to 95% shorter than at least a portion of the plurality of the second protrusions.  
   
   
       15 . An absorbent article comprising the mechanical fastening system of  claim 10 .
