Abstract
A high pulp content nonwoven composite fabric is disclosed. The composite fabric contains more than about 70 percent, by weight, pulp fibers which are hydraulically entangled into a continuous filament substrate. This high pulp content composite nonwoven fabric may be used as a heavy duty wiper or as a fluid distribution material, cover material, and/or absorbent material in an absorbent personal care product. Also disclosed is a method of making the high pulp content nonwoven composite fabric.
Claims17
A high pulp content hydraulically entangled nonwoven composite fabric comprising:
- from about 10 to about 25 percent, by weight, of a nonwoven continuous filament substrate component;
- and
- more than about 70 percent, by weight, of a fibrous component consisting of pulp fibers.
A high pulp content hydraulically entangled nonwoven composite fabric comprising:
- from about 10 to about 25 percent, by weight, of a nonwoven continuous filament substrate component having a bond density greater than about 250 pin bonds per square inch and a total bond area of less than about 30 percent;
- and
- more than about 70 percent, by weight, of a fibrous component consisting of pulp fibers.
A high pulp content hydraulically entangled nonwoven composite fabric comprising:
- from about 10 to about 25 percent, by weight, of a nonwoven continuous spunbond polyolefin filament component having a bond density greater than about 250 pin bonds per square inch and a total bond area of less than about 30 percent;
- and
- more than about 70 percent, by weight, of a fibrous component, said fibrous component consisting of a mixture of about 50 percent, based on the weight of the fibrous component, Northern softwood fiber pulp;
- 20 percent, based on the weight of the fibrous component;
- Southern softwood fiber pulp;
- and about 30 percent, based on the weight of the fibrous component, secondary fiber pulp.
