A printable material which includes a flexible first layer having first and second surfaces and a second layer. The first layer may be a film or a cellulosic nonwoven web. The second layer overlays and is bonded to the first surface of the first layer and includes a nonwoven web. The first layer has a basis weight of from about 20 to about 140 grams per square meter. The thermoplastic polymer has a melting point of from about 90&deg; C. to about 250&deg; C. and the second layer has a basis weight of at least about 10 grams per square meter. The first layer may be a cellulosic nonwoven web, such as a latex-impregnated paper. The second layer may be thermally bonded to the first layer or bonded by an adhesive. A release layer may be present between the first layer and the heat-activated adhesive. The second layer may contain from about 0.1 to about 20 percent by weight, based on the weight of the second layer, of a material which increases the viscosity of an ink jet ink when printed on the second layer. The second layer also may contain from about 0.1 to about 5 percent by weight, based on the weight of the second layer, of a cationic polymer. When the second layer is prepared from a thermoplastic polymer, the ink jet printable material may be used as a heat transfer material. Methods of preparing the printable material also are described.

Printable material

An improved nonwoven web composite is formed by combining splittable bicomponent thermoplastic filaments with a component selected from other fibers and particles. The bicomponent filaments include distinct regions of first and second incompatible polymers extending the length of the filaments. After the bicomponent filaments are combined with the other fibers and/or particles, the bicomponent filaments are caused to split lengthwise along boundaries between the regions of different polymers, resulting in a web or matrix of finer filaments which entrap, ensnare and contain the other fibers and/or particles within the web or matrix. The nonwoven web composite is particularly useful for making absorbent articles, which require durability and optimum levels of absorbent fibers and/or particles.

A personal care absorbent article made of a nonwoven material having a plurality of polymeric fibers having a fiber interior comprising at least one of a liquid fluid and a gaseous fluid. The nonwoven materials are produced by heating at least one polymer to a melting point, forming a molten polymer; extruding the molten polymer through a plurality of capillaries, injecting a liquid fluid and/or a gaseous fluid into the molten polymer prior to, during and/or after the extruding step, forming a plurality of fluid-filled polymeric fibers, wherein the liquid fluid and/or gaseous fluid is dispersed within the interior of the polymeric fibers, and depositing the fluid-filled polymeric fibers onto a web forming surface, forming a nonwoven material.

Personal care articles with reduced polymer fibers

The present invention is directed to crimped and resilient polymeric fibers and to fabrics and laminates made from the fibers. In general, the fibers are produced by crimping a polymeric fiber and then cross-linking a polymer and/or monomer contained within the fiber. Cross-linking the polymer makes the crimp contained with the fiber more permanent and more resilient. When formed into a nonwoven web, the fibers produce high loft fabrics which are resilient to compressive forces. Nonwoven webs made in accordance with the present invention are particularly well suited for use in filter products and liquid absorbent products.

Crimped polymeric fibers and nonwoven webs made therefrom with improved resiliency

The present invention provides continuously crimped propylene polymer nonwoven fabrics as well as processes for forming crimped multicomponent propylene polymer fibers by melt-attenuating extruded multicomponent fibers with heated or unheated air wherein the fibers spontaneously crimp without the need for additional heating and/or stretching steps.
