ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to fabric dye maintenance compositions which comprise one or more dye maintenance compounds which can be oligomers, polymers, co-polymers, and the like which comprise one or more monomers which results in the final dye maintenance compound having a net positive charge. Compositions comprising the dye maintenance polymers of this invention impart appearance and integrity benefits to fabrics and textiles treated with solutions formed from such compositions.
BACKGROUND OF THE INVENTION
It is, of course, well known that alternating cycles of using and laundering fabrics and textiles, such as articles of worn clothing and apparel, will inevitably adversely affect the appearance and integrity of the fabric and textile items so used and laundered. Fabrics and textiles simply wear out over time and with use. Laundering of fabrics and textiles is necessary to remove soils and stains which accumulate therein and thereon during ordinary use. However, the laundering operation itself, over many cycles, can accentuate and contribute to the deterioration of the integrity and the appearance of such fabrics and textiles.
Deterioration of fabric integrity and appearance can manifest itself in several ways. Short fibers are dislodged from woven and knit fabric/textile structures by the mechanical action of laundering. These dislodged fibers may form lint, fuzz or “pills” which are visible on the surface of fabrics and diminish the appearance of newness of the fabric. Further, repeated laundering of fabrics and textiles, especially with bleach-containing laundry products, can remove dye from fabrics and textiles and impart a faded, worn out appearance as a result of diminished color intensity, and in many cases, as a result of changes in hues or shades of color.
Given the foregoing, there is clearly an ongoing need to identify materials which could be added to fabric treatment products, specifically to rinse added fabric conditioners, pre-wash spray on compositions, pre-soak compositions as well as after wash or between wash malodor control or fabric re-freshening compositions, materials which would associate themselves with the fibers of the fabrics and textiles thereby reducing, abating, or minimizing the tendency of the fabric/textiles to deteriorate in appearance. Any such fabric treatment/fabric maintenance composition additive material should, of course, be able to benefit fabric appearance and integrity without unduly interfering with the ability of the balance of laundry products to perform their intended function. The present invention is directed to the use of dye maintenance polymers in fabric treatment and fabric enhancement compositions which perform in this desired manner.
SUMMARY OF THE INVENTION
The present invention meets the aforementioned need in that it has been surprisingly discovered that fabric which is treated, and subsequently re-treated with the compositions of the present invention, will resist normal fading and color loss without regard to the circumstances, inter alia, due to mechanical wear and abrasion. In addition, fabric which has not been treated can have the loss of fabric dye attenuated by adding the compositions of the present invention to the laundry cycle as an adjunct via pre-soak, rinse additive, etc. The compositions of the present invention can be added is any manner, inter alia, as part of a formulation or as a separate composition.
The first aspect of the present invention relates to compositions providing dye protection benefits to fabric comprising:
