TH18036A - "Compressible loop construction for hook-and-loop fastening systems" - Google Patents

Abstract

The invention will involve an improved loop of hook and loop attachment system. A two-layer component, including a compressed flexible backing and a layer of loop material. This loop material will Is placed next to the lower surface of the backing material, and therefore the loops of many fibers are sewn or knit through the backing material. Behind this to Make many hoops that will extend above The upper face of the backing material due to the nature of the elasticity of the backing material. When the hook part was taken Into the loop with the back material is pressed. Thus, it opens the greater portion of the unique loop for the attachment of the hook. When the hook is fastened, the back backing expands to form the opening of the smaller loop. More specific between sections Hook and loop hooks will arise and there will be Little space between hook and loop parts, due to This creates a very firm hook and loop system. It is prominently illustrated by the increased peel-off force compared to conventional loop structures. In order to increase the tensile strength Up to this structure A layer of loop material may have an adhesive to bond this fiber and Holding that loop like More stable in order to reduce the shift Conversion of that There was no seizure during the separation. Of the hook part, leaving the loop part at the end of this The glue used may be a sensitive adhesive. Continue pressure so that Will allow the attachment of the loop structure to With other base layers Such as diaper wrap, etc.
