Abstract
The present invention is directed to thermoformable ion-sensitive compositions having improved processability. In addition, the present invention is directed to a process of making water-dispersible fibers, films and fabrics, which maintain their structural integrity and strength when in use, but dissolve and disperse when placed in contact with large amounts of water, such as in a conventional sink or toilet. Moreover, the present invention is directed to water-dispersible products, including flushable products such as personal care products, diapers, incontinence devices, release liners, feminine napkins, product packaging, etc., which contain fibers, films and fabrics formed from the water-sensitive compositions.
Claims20
A nonwoven fabric comprising a plurality of multicomponent fibers, wherein each multicomponent fiber comprising at least one water-sensitive polymer and at least one additional polymer, the at least one additional polymer being a polylactide, a polyolefin-grafted with one or more polar groups, or a second aliphatic polyester.
A nonwoven fabric containing multicomponent fibers, wherein the multicomponent fibers comprise at least one water-sensitive polymer blended with at least one additional polymer, the at least one additional polymer being a polylactide, a polyolefin-grafted with one or more polar groups, or a second aliphatic polyester;
- and wherein the water-sensitive polymer is ion triggerable.
A nonwoven fabric comprising a plurality of multicomponent fibers, wherein each multicomponent fiber comprises a water-sensitive copolyester blended with a polylactide, and wherein the water-sensitive copolyester is ion triggerable.
