Abstract
A loop material for a hook and loop fastening system composed of: 1) a backing material; and 2) a layer of a nonwoven spunbond web attached to the backing material, the nonwoven spunbond web comprising a plurality of continuous intertwined filaments, each having a diameter of about 25 to about 100 microns, the plurality of filaments laid randomly to define a plurality of intertwined loop springs, each having a diameter of about 0.5 to about 3 millimeters.
Claims16
A loop material for a hook and loop fastening system comprising:
- a backing material;
- and
- a layer of a nonwoven spunbond web attached to the backing material and having a loop material surface, the nonwoven spunbond web comprising a plurality of continuous intertwined filaments, each having a diameter of about 25 to about 100 microns, the plurality of filaments laid randomly to define a plurality of intertwined loop springs tending to maintain a "z" axis orientation 90.degree. from said loop material surface, each of said plurality of springs having a diameter of about 0.5 to about 3 millimeters.
An outer cover for a personal care absorbent product, the outer cover comprising a loop material composed of a backing material and a layer of a nonwoven spunbond web having a loop material surface, the spunbond web comprising a plurality of continuous intertwined filaments, each having a diameter of about 25 to about 100 microns, the plurality of filaments laid randomly to define a plurality of intertwined loop springs tending to maintain a "z" axis orientation of about 90.degree. from said loop material surface, each of said plurality of springs having a diameter of about 0.5 to 3 millimeters.
A nonwoven spunbond web adapted to form a loop material for a hook and loop fastening system, the web having a loop material surface and comprising a plurality of continuous intertwined filaments, each having a diameter of about 25 to about 100 microns, the plurality of filaments laid randomly to define a plurality of intertwined loop springs tending to maintain a "z" axis orientation of about 90.degree. from said loop material surface, each of said plurality of springs having a diameter of about 0.5 to about 3 millimeters.
