Appl. No.:

10/234081

Assignee:

Tredegar Film Products Corporation - Richmond VA

International Classification:

B32B005/26
B32B027/12
B32B003/10

US Classification:

156229, 156 731, 156160, 156163, 156182, 156290, 428141, 442407, 442394

Abstract:

An elastomeric film is bonded between two or more layers of nonwoven webs formed of nonelastomeric thermoplastic fibers. The laminate has, in a predefined transverse direction, an elastic elongation value greater than the predefined elastic elongation value of the nonwoven webs, and an ultimate force to break in the predefined transverse direction of at least 3000 g/in. The laminate advantageously provides a tear resistant, multiple ply, fabric that is soft to the touch as a result of the outwardly disposed nonwoven webs, and has a high elastic modulus. The laminate is particularly useful in applications where closure portions of a product must be stretched to keep the product in place when worn.

International Classification:

B32B 37/00

US Classification:

156 731, 156161, 156164, 156229

Abstract:

A method for producing a composite web includes supplying two or more webs to an activation mechanism, where the webs are in an unbonded state relative to each other. The method further entails simultaneously activating the webs while they are in a face to face relationship and in an unbonded state, and then bonding the webs to form a composite web.

Abstract:

A method for manufacturing composite webs and composite webs made thereby in which the web includes a perforated thermoplastic film and one or more nonwoven webs. The method provides a perforated thermoplastic film, a creped nonwoven web, the webs are fed in a face to face relationship to be bonded. The perforated thermoplastic film and the creped nonwoven web are bonded in a face to face relationship at a plurality of points of contact such that the creped structure of the nonwoven web is maintained and the composite web has a nonwoven face and a film face. The composite webs are extensible at least in the direction of the creping.

Abstract:

A multi-layered web is provided that includes an elastic web bonded to an inelastic web. The inelastic web has extensible and inextensible regions arranged along the machine direction. In the extensible regions, the inelastic web is bonded to the elastic web in a creped structure that is extensible by virtue of the creping. A continuous process is provided to manufacture a multi-layer web having extensible regions that are conjoined with regions that are inextensible by varying the tension that is applied during manufacture of the multi-layer web. The apparatus comprises an elastic web that is fed into a bonding nip, into which one or more inelastic webs are also provided. The elastic web is fed into the bonding nip under a tension that is alternated between a low value that is sufficient to ensure processing stability, and a higher value that provides an elongation to the elastic web. During the low tension phase of the bonding process the inextensible region is formed in the multi-layer web due to the inextensibility of the web.
