Benefits of technology

The present invention is a new technology with various benefits. This technology is not limited to the specific forms described and includes all modifications, equivalents, and alternatives that meet its goals.

Problems solved by technology

However, after using the fibrous water-soluble unit dose article, when the consumer removes his or her clothing from the wash, he or she may notice that the scent of the clothing is not as intense as the scent of the fibrous water-soluble unit dose article itself.
Thus, the expectations of the consumer are not met.
Thereafter, the perfume that did deposit onto the fabric may be lost as the clothing undergoes drying, especially if the drying process incorporates heat.
However, perfumes (e.g., neat oils) and / or encapsulated perfumes may be unstable when placed with other liquid ingredients, e.g., in a liquid detergent.
In addition, there may a limit as to how much perfume and / or encapsulated perfumes can be added to a water-soluble, solid substrate, e.g., fibrous ply in a fibrous water-soluble unit dose article, without causing leakage or premature dissolution of the substrate.

example 1

[0331]As illustrated in FIG. 3, a first layer of fibrous elements is spun using a first spinning beam and collected on a forming belt. The forming belt having the first layer of fibers then passes under a second spinning beam that is modified with a particle addition system. The particle addition system is capable of substantially injecting particles toward a landing zone on the forming belt that is directly under the fibrous elements from the second spinning beam. Suitable particle addition systems may be assembled from a particle feeder, such as a vibratory, belt or screw feeder, and an injection system, such as an air knife or other fluidized conveying system. In order to aid in a consistent distribution of particles in the cross direction, the particles are preferably fed across about the same width as the spinning die to ensure particles are delivered across the full width of the composite structure. Preferably, the particle feeder is completely enclosed with the exception of t...

Abstract

Described herein is a household care composition, which delivers active agents onto fabric, in the form of a water-soluble unit dose article comprising a water-soluble fibrous structure and an encapsulated perfume composition, as well as methods for making the article and methods for treating fabrics using the article.

Description

FIELD OF THE INVENTION[0001]Described herein is a household care composition, which delivers active agents onto fabric, in the form of a water-soluble unit dose article comprising a water-soluble fibrous structure and an encapsulated perfume, as well as methods for making the article and methods for treating fabrics using the article.BACKGROUND OF THE INVENTION[0002]Water-soluble unit dose articles are desired by consumers as they provide a convenient, efficient, and clean way of dosing a fabric or hard surface treatment composition. Water-soluble unit dose articles provide a measured dosage of a treatment composition, thereby avoiding over or under dosing. Fibrous water-soluble unit dose articles are of increasing interest to consumers. The technology related to such articles continues to advance in terms of providing the desired active agents with the articles enabling the consumers to do the job that they wish to accomplish.[0003]Consumers desire fibrous water-soluble unit dose a...
