ABSTRACT:
TECHNICAL FIELD
The present invention relates to treating compositions comprising a polysaccharide, and to a method for treating fabrics, natural fibers, such as cellulosic fibers, more particularly cotton, rayon, ramie, jute, flax, linen, polynosic-fibers, Lyocell, poly/cotton, other cotton blends and mixtures thereof, with such compositions for providing the fabrics with improved color appearance and/or pill prevention and/or abrasion resistance and/or wrinkle resistance and/or shrinkage resistance compared to treating compositions without such polysaccharides.
BACKGROUND OF THE INVENTION
Consumer desirability for fabric garments that “look like new”, or in other words, fabric garments that retain their “new” appearance, especially with respect to their color appearance has risen.
However, colored garments, especially cotton, rayon and linen garments, have a tendency to wear and show appearance losses. A portion of this color loss may be attributed to abrasion in the laundering process, particularly in automatic washing machines and automatic laundry dryers.
Accordingly, there is a need for treating compositions that provide, refurbish, restore and/or improve the color appearance and/or pill prevention and/or abrasion resistance and/or wrinkle resistance and/or shrinkage resistance of fabrics.
SUMMARY OF THE INVENTION
The present invention is a treating composition comprising polysaccharides and a method for imparting color appearance and/or pill prevention and/or abrasion resistance and/or wrinkle resistance and/or shrinkage resistance properties to fabrics such as cotton, rayon, ramie, jute, flax, linen, polynosic-fibers, Lyocell, poly/cotton, other cotton blends and mixtures thereof.
In accordance with one aspect of the present invention, a treating composition comprising polysaccharides is provided.
In accordance with yet another aspect of the present invention, a method for treating a fabric in need of treatment comprising contacting the fabric with an effective amount of a polysaccharide-containing treating composition such that the treating composition treats the fabric is provided.
A preferred treating composition in accordance with the present invention comprises one or more polysaccharides and one or more cleaning adjunct materials as described hereinafter, preferably selected from the group consisting of builders, bleaching agents, dye transfer inhibiting agents, chelants, dispersants, polysaccharides, softening agents, suds suppressors, carriers, enzymes, enzyme stabilizing systems, polyacids, soil removal agents, anti-redeposition agents, hydrotropes, opacifiers, antioxidants, bactericides, dyes, perfumes, brighteners and mixtures thereof, and optionally, but preferably further comprising a surfactant. Preferably, the treating composition is in the form of powder or granules. However, the treating composition may be in the form of a liquid such as an aqueous or non-aqueous heavy duty liquid detergent composition, a liquid for spray application, or a solid, such as a concentrated stick, for rubbing onto the fabric.
Preferably, the treating composition is applied to the fabric through the wash and/or through the rinse cycles. However, the treating composition can be applied to the fabric prior to the wash and/or after the wash and/or rinse cycles, such as during or prior to ironing, if needed.
All percentages and proportions herein are by weight, and all references cited herein are hereby incorporated by reference, unless otherwise specifically indicated.
DETAILED DESCRIPTION OF THE INVENTION
Definitions
The treating compositions of the present invention comprise an “effective amount” of a polysaccharide. An “effective amount” of a polysaccharide is any amount capable of measurably improving the color appearance and/or pill prevention and/or abrasion resistance and/or wrinkle resistance and/or shrinkage resistance properties of a fabric when it is washed. In general, this amount may vary quite widely.
“Treating composition(s)” herein is meant to encompass generally laundry and/or fabric care compositions and/or fabric conditioners.
Polysaccharide-Containing Treating Composition
In a preferred embodiment, the treating compositions of the present invention comprise an effective amount of one or more polysaccharides and are preferably free of starch and/or starch derivatives and/or resins. Preferably, the treating compositions further comprise one or more cleaning adjunct materials. These treating compositions are useful in the methods of the present invention.
It is desirable that the polysaccharide is present in the treating composition of the present invention in an amount in the range of from about 0.01% to about 50% by weight of the treating composition, more preferably from about 0.5% to about 10% by weight of the treating composition. Furthermore, it is desirable that the polysaccharide is present in the wash, soaking and/or spray-treatment solution in amount in the range of from about 2 ppm to about 25000 ppm, more preferably from about 10 ppm to about 5000 ppm.
The treating composition can include conventional detergent ingredients, such as one or more of the following ingredients selected from the group consisting of surfactants, builders, bleaches, bleach activators, bleach catalysts, enzymes, enzyme stabilizing systems, soil release/removal agents, suds suppressors, polyacids, anti-redeposition agents, hydrotropes, opacifiers, antioxidants, bactericides, dyes, perfumes, carriers and brighteners. Examples of such ingredients are generally described in U.S. Pat. No. 5,576,282.
Forms of Compositions
The treating compositions of the present invention can be in solid (powder, granules, bars, tablets), dimple tablets, liquid, paste, gel, spray, stick or foam forms.
The liquid forms can also be in a “concentrated” form which are diluted to form compositions with the usage concentrations, as given hereinbelow, for use in the “usage conditions”. Concentrated compositions comprise a higher level of polysaccharide, typically from about 1% to about 99%, preferably from about 2% to about 65%, more preferably from about 3% to about 25%, by weight of the concentrated treating composition. Concentrated compositions are used in order to provide a less expensive product. When a concentrated product is used, i.e., when the polysaccharide is from about 1% to about 99%, by weight of the concentrated composition, it is preferable to dilute the composition, preferably with water, before treating a fabric in need of treatment. Preferably, the water content of the “concentrated” form is less than 40%, more preferably less than 30%, most preferably less than 20% by weight of the detergent composition.
The present invention also relates to polysaccharide-containing treating compositions incorporated into a spray dispenser to create an article of manufacture that can facilitate treatment of fabric articles and/or surfaces with said compositions containing the polysaccharide and other optional ingredients at a level that is effective, yet is not discernible when dried on the surfaces. The spray dispenser comprises manually activated and non-manual powered (operated) spray means and a container containing the treating composition. The articles of manufacture preferably are in association with instructions for use to ensure that the consumer applies sufficient polysaccharide to provide the desired benefit.
Typical compositions to be dispensed from a sprayer contain a level of polysaccharide of from about 0.01% to about 5%, preferably from about 0.05% to about 2%, more preferably from about 0.1% to about 1%, by weight of the usage composition.
For wash-added and rinse-added methods, the article of manufacture can simply comprise a liquid or granular solid polysaccharide-containing treating composition and a suitable container.
Wash-added compositions, including liquid and granular detergent compositions and wash additive compositions typically contain a level of polysaccharide of from about 0.01% to about 30%, preferably from about 0.5% to about 20%, more preferably from about 1% to ab
