Abstract

A composite fabric comprising a necked and creped spunbond nonwoven web of monocomponent fibers hydraulically entangled with a fibrous component that comprises cellulosic fibers. The nonwoven web contains thermoplastic fibers and the fibrous component comprises greater than about 50% by weight of the fabric.

Claims (12)

1. A method for forming a fabric comprising:

necking a spunbond web of monocomponent thermoplastic fibers, said spunbond web defining a first surface and a second surface;

creping at least one surface of said spunbond web; and

thereafter, hydraulically entangling said spunbond web with a fibrous component that contains cellulosic fibers, wherein said fibrous component comprises greater than about 50% by weight of the fabric.

2. A method as defined in claim 1 , further comprising adhering said first surface of said spunbond web to a first creping surface and creping said web from said first creping surface.

3. A method as defined in claim 2 , further comprising applying a creping adhesive to said first surface of said spunbond web in a spaced-apart pattern such that said first surface is adhered to said creping surface according to said spaced-apart pattern.

4. A method as defined in claim 3 , further comprising adhering said second surface of said spunbond web to a second creping surface and creping said web from said second surface.

5. A method as defined in claim 4 , further comprising applying a creping adhesive to said second surface of said spunbond web in a spaced-apart pattern such that said second surface is adhered to said creping surface according to said spaced-apart pattern.

6. A method as defined in claim 1 , wherein said thermoplastic fibers are polyolefin and have a denier per filament of less than about 3.

7. A method as defined in claim 1 , further comprising point bonding said spunbond web.

8. A method as defined in claim 1 , wherein said fibrous component comprises from about 60% to about 90% by weight of the fabric.

9. A wiper made in accordance with the method of claim 1 .
