Description: MODIFIED STARCH-BASED POLYMER-CONTAINING FABRIC CARE COMPOSITIONS AND METHODS EMPLOYING SAME CROSS REFERENCE TO RELATED APPLICATIONS This application claims priority under 37 U.S.C. § 119(e) to TJ. S. Provisional Application Serial No.60/198,710, filed April 20, 2000 (Attorney Docket No.8045P). TECHNICAL FIELD The present invention relates to compositions, in any form, preferably liquid or granular form, for use in laundry and/or fabric care applications, wherein the compositions comprise certain modified starch-based polymer and/or oligomer materials which impart appearance and integrity benefits to fabrics and textiles laundered in washing solutions fomied from such compositions. The modified starch-based polymer and/or oligomer materials can be added to wash solutions by incorporating them into a laundry and/or fabric care composition, a fabric softener or by adding them separately to the washing solution. The modified starch-based polymer and/or oligomer materials are described herein primarily as liquid or granular detergent additives but the present invention is not meant to be so limited. 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. Also, dislodged fibers are more susceptible to damage which causes increased light scattering to decrease fabric color depth or strength. 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 laundry detergent products that would associate themselves with the fibers of the fabrics and textiles laundered using such detergent products and thereby reduce or minimize the tendency of the laundered fabric/textiles to deteriorate in appearance. Any such detergent product additive material should, of course, be able to benefit fabric appearance and integrity without unduly interfering with the ability of the laundry detergent to perform its fabric cleaning function. The present invention is directed to the use of modified starch-based polymer and/or oligomer materials in laundry and/or fabric care applications which perform in this desired manner. SUMMARY OF THE INVENTION Modified starch-based polymer and/or oligomer materials, preferably modified amylose (represented by Formula I below) and/or modified amylopectin (represented by Formula II below) both of which are described in Kirk-Othmer's Encyclopedia of Chemical Technology 4 th Edition, Vol. 22, pp. 701-703, starch, generally, is described at pp. 699-719, which are suitable for use in laundry and/or fabric care operations and provide the desired fabric appearance and integrity benefits can be characterized by the following general formulas, alone or in combination: or II wherein each R is selected from the group consisting of R2, Re, and wherein: each R2 is independently selected from the group consisting of H and C1 -C4 alkyl; O each Rcis -C^ -C-OZ wherein each Z is independently selected from the group consisting of M, R2, e, and R H ; each R H is independently selected from the group consisting of C5 -C20 alkyl, C5-C7 cycloalkyl, C7-C20 alkylaryl, C7-C20 arylalkyl, substituted alkyl, hydroxyalkyl, Cι -C20 alkoxy-2-hydroxyalkyl, C7-C20 alkylaryloxy-2-hydroxyalkyl, (R4)2N-alkyl, (R4)2N-2- hydroxyalkyl, ^4)3 N-alkyl, ( 4)3 N-2-hydroxyalkyl, Cg-C^ aryloxy-2-hydroxyalkyl, O R 5 O R 5 O R 5 O I I I II I II I II — C CH C CH 2 — C CH 2 CH C-OM and each R4 is independently selected from the group consisting of H, Cι -C20 alkyl, C5-C7 cycloalkyl, C7-C20 alkylaryl, C7-C20 arylalkyl, aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, piperidinoalkyl, mo holinoalkyl, cycloalkylaminoalkyl and hydroxyalkyl; each R5 is independently selected from the group consisting of H, Cι -C20 alkyl, C5-C7 cycloalkyl, C7-C20 alkylaryl, C7-C20 arylalkyl, substituted alkyl, hydroxyalkyl, (R 4 ) 2 N-alkyl, and (R 4 ) 3 N-alkyl; wherein: M is a suitable cation selected from the group consisting of Na + , K + , l/2Ca 2+ , l/2Mg 2+ , or " "TSfH j R k wherein j and k are independently from 0 to 4 and wherein j + k is 4 and R in this formula is any moiety capable of forming a cation, preferably methyl and/or ethyl group or derivative; each x is from 0 to about 5; each y is from about 1 to about 5; and provided that: the Degree of Substitution for group R H is between about 0.001 and about 0.1, more preferably between about 0.005 and about 0.05, and most preferably between about 0.01 and about 0.05; - the Degree of Substitution for group R c wherein Z is H or M is between about 0 and about 2.0, more preferably between about 0.05 and about 1.0, and most preferably between about 0.1 and about 0.5; if any R H bears a positive charge, it is balanced by a suitable anion; and two R4's on the same nitrogen can together form a ring structure selected from the group consisting of piperidine and morpholine. The modified starch-based polymer and/or oligomer materials defined above can be used as a washing solution additive in either granular or liquid form. Alternatively, they can be admixed to granular detergents, dissolved/dispersed in liquid laundry and/or fabric care compositions or added to a fabric softening composition. The forgoing description of uses for the modified starch- based polymer and/or oligomer materials defined herein are intended to be exemplary and other uses will be apparent to those skilled in the art and are intended to be within the scope of the present invention.
