Problems solved by technology

[0004] Accordingly, there is a need for soluble fibrous structures that dissolve completely and / or satisfactorily under intended conditions of use, especially at consumer-relevant times, to deliver their intended benefits, but do not have the same properties as those known to be soluble. Negative effects associated with fiber structure

Abstract

Soluble fibrous structures and more particularly soluble fibrous structures that contain one or more fibrous elements, such as filaments, having one or more fibrous element-forming materials and one or more active agents present within the fibrous elements, wherein the fibrous structure exhibits improved dissolution properties compared to known soluble fibrous structures, and method for making such improved fibrous structures are provided.

Description

technical field [0001] The present invention relates to dissolvable fibrous structures and more particularly to dissolvable fibrous structures comprising one or more fibrous elements, such as filaments, comprising one or more fibrous element forming materials and one or more An active agent wherein the fibrous structure exhibits improved dissolution characteristics compared to known dissolvable fibrous structures; and a method for preparing such improved fibrous structures which simultaneously exhibit consumer-acceptable physical Properties such as strength, flexibility, elongation and modulus. Background technique [0002] Dissolvable fibrous structures comprising one or more fibrous elements, such as filaments, comprising one or more fibrous element forming materials such as polymers, and present within the fibrous element one or more active agent. These known soluble fibrous structures generally comprise a plurality of filaments comprising a fibrous element forming mate...
