Abstract
Filaments that contain a filament-forming material and an additive, nonwoven webs, and methods for making such filaments are provided.
Claims43
A filament comprising one or more filament-forming materials and one or more non-perfume active agents that are releasable from the filament when the filament is exposed to conditions of intended use, wherein the total level of the one or more filament-forming materials present in the filament is less than 65% by weight on a dry filament basis and the total level of the one or more non-perfume active agents present in the filament is greater than 35% by weight on a dry filament basis.
The filament according to claim 31 wherein the filament exhibits a water content of greater than 0% to less than 15% as measured according to the Water Content Test Method described herein.
A method for making a filament, the method comprises the steps of:
- a. providing a filament-forming composition comprising one or more filament-forming materials and one or more non-perfume active agents;
- b. spinning the filament-forming composition into one or more filaments comprising the one or more filament-forming materials and the one or more non-perfume active agents that are releasable from the filament when the filament is exposed to conditions of intended use, wherein the total level of the one or more filament-forming materials is less than 65% and the total level of the one or more non-perfume active agents present in the filament is greater than 35% by weight on a dry filament basis.
A filament comprising one or more filament-forming materials and one or more non-perfume active agents that are releasable from the filament when the filament is exposed to conditions of intended use, wherein the total level of the one or more filament-forming materials present in the filament is less than 65% by weight on a dry filament basis and the total level of the one or more non-perfume active agents present in the filament is greater than 35% by weight on a dry filament basis, wherein the active agents comprise one or more surfactants, one or more enzymes, and one or more perfumes.
