International Classification:

B32B 3100

US Classification:

156183, 156296, 1563084, 156167

Abstract:

A stabilized creped nonwoven web and a method for producing the same, wherein a creped nonwoven web is thermally stabilized, for example by through-air-bonding or embossing, to produce the stabilized creped nonwoven web. The stabilized creped nonwoven web having increased tensile strength in the machine direction and an enhanced appearance. The stabilized creped nonwoven web of this invention id capable of withstanding a tensile force or load in a machine direction of at least about 2. 0 lbs. at 20% strain and a tensile force or load in the machine direction of at least about 5. 0 lbs. at 50% strain.

International Classification:

D01D 522

US Classification:

425462, 425DIG 217, 425463, 4253822

Abstract:

Robust round homofilament fibers are meltspun from a spinneret having two conjoined capillaries of different length to diameter ratio to induce differential shear to produce fiber crimping. Crimping may further be aided by quenching of the fibers.

US Classification:

428370

Abstract:

There is provided in accordance with the present invention a helically crimped conjugate fiber containing at least a first composition and a second composition. The first and second compositions respectively contain different thermoplastic polymer having different solidification periods, and at least one of the two compositions contains a nucleating agent. Additionally provided is a process for controlling the level of crimps in the conjugate fiber.

International Classification:

D04H 312
D04H 314

US Classification:

156167

Abstract:

A shaped nonwoven fabric comprises continuous spunbond filaments made by directly forming the spunbond filaments into a web in a single process. The fabric has an array of discrete surface features such as apertures or projections, or both. The spunbond filaments are bonded together with an adhesive polymeric component so that the shape of the fabric is retained. The fabric can be engineered to have particular fluid handling properties, strength properties, abrasive properties and aesthetic properties. Articles such as personal care products, garments, medical products and cleaning products are also disclosed.
