  • Method for producing a spun-bonded nonwoven web with improved abrasion resistance
    Patent number: 6720278
    Abstract: The present invention relates to a method for improving the abrasion resistance of a spun-bonded nonwoven without substantially adversely affecting its hand or drape characteristics, by incorporating low melt binder fibers into the web during the laydown phase of the spun-bonded nonwoven production process. More specifically, improved abrasion resistance is achieved by intimately blending continuous binder fibers with the primary extruded fibers in a spun-bonded nonwoven web. Also encompassed within this invention is a spun-bonded nonwoven fabric having improved abrasion resistance and comprised of primary extruded fiber and low melt binder fiber such that the binder fiber comprises between about 1 and about 50 weight percent on weight of the spun-bonded nonwoven fabric.
