BACKGROUND OF THE INVENTION
In the modern world the vast majority of clothing is made from woven fabrics, and the art of weaving is many centuries old.
Indeed the invention of weaving is generally attributed to the Ancient Egyptians. Yarns were produced from natural cotton, wool, or linen fibers, and garments made from fabrics woven from these yarns often creased badly in wear and, when washed or dry cleaned, required considerable time and effort with a steam pressing machine or iron to restore them to a pristine appearance.
200~162 With the increasing standard of living, there has been a general demand for a release from the labor involved in pressing cleaned clothes. At the same time the increased cost of labor has raised the expense of laundry and commercial dry cleaning con-siderably. This has resulted in additional pressure being brought to bear on textile technologists to produce fabrics and garments that can be simply cleaned and are ready to wear, and will keep a good appearance during wear.
Textile manufacturers have i~plemented two major improvements in wash-and-wear garments: (1) the use of cross-linking resins on cotton containing garments, and (2) the use of synthetics and synthetic blends. Although these two implementations have made major strides in reducing the wrinkling of a garment, consumers are still dissatisfied with the results and demand pressing after a cleaning operation.
Starch has been used for many years in fabric treatment to restore and retain them in a pristine appearance.

200~62 -2a-DETAILED DESCRIPTION OF THE INVENTION
The liquid starch composition preferably contains a liquid selected from the group con~i~ting of weak aqueous surfactant solutions, lower molecular weight C,-C4 alcohols and lllixl~ es thereof.
This invention relates to liquid starch compositions comprising curable amine functional silicone (CAFS) for improved fabric wrinkle reduction. In another respect this invention relates to methods of using such curable amine functional silicone compositions in the treatment of fabrics for improved wrinkle reduction and fabric shape retention. Preferred compositions are liquids which are sprayed onto or rinsed into the laundered fabrics. These preferred compositions are aqueous starch based D
liquids which contain from about 0.1% to about 33%, more prefer-ably from about 0.5% to about 20% of the curable amine functional silicone. The more concentrated compositions can be diluted in a rinse. The lesser concentrated compositions are sprayed directly onto fabric.
The term "wrinkle reduction" as used herein means that a treated fabric is less likely to wrinkle or has less wrinkles after being worn or after a laundering operation than it would otherwise have after a comparable operation.
10The term "shape retention" as used herein means that a pre-ironing CAFS/starch spray treated fabric is less likely to wrinkle or lose its ironed shape after being worn than it would otherwise after a comparable starch treat~ment.
In commonly assi~ned and copending C~n~ n Pat. Application Ser.
15No. 569,870, Coffindaffer and Won~, for a fabric softener composition, filed June 20, 1988, the present application is disclosed.
It is important to differentiate the curable amine functional silicones and the noncurable amine functional silicones. The 20curable amine functional silicone molecules have the ability to react one with the other to yield a polymeric elastomer of a much higher molecular weight compared to the original molecule. Thus, "curing" often occurs when two CAFS molecules or polymers react, yielding a polymer of a higher molecular weight. [ ~ SiOH + ~ SiOH
25~~ SiOSi ~ + H20]. A more detailed version of the curing reaction is given below. This "cure" is defined herein as the formation of silicon-oxygen-silicon linkages. The silicon-oxygen-silicon linkage cure is distinguished from polysiloxane bridging reactions between amino groups and carboxyl (or epoxy) groups as 30disclosed in EPA 058,493, Ona et al., published Aug. 25, 1982, (Bulletin 82/34) .
Curable amine functional silicones are commercially avail-able; e.g., Dow Corning Silicone 531 and 536, General Electric SF
1706, SWS Silicones Corp. SWS E-210 are commercially available 35curable amine functional silicones widely marketed for use in hard surface care, such as in auto polishes, where detergent resistance and increased protection are very important.
~00~162 Several fabric care compositions containing curable amine functional silicones are herein disclosed. Several methods of using curable amine functional silicones for wrinkle reduction fabric care are also disclosed.
The CAFS compositions of this invention are used with a suitable liquid carrièr. The term "carrier" as used herein in general means any suitable vehicle that is used to deliver the CAFS and deposit it on the fabric. This invention comprises a liquid starch composition comprising the CAFS plus starch and a suitable carrier.
In a preferred execution, about 0.1% to about 10% by weight of an emulsified curable amine functional silicone is mixed into a suitable commercially available pump spray starch composition.
The result is a spray starch composition that provides an improved wrinkle reduction benefit to fabric sprayed therewith. Suitable commercially available spray starch compositions are based on water and a suitable emulsifier. Care must be taken to use CAFS
emulsifiers which are compatible with the starch and CAFS to avoid deemulsification. A second execution includes a laundry rinse wherein the level of CAFS is present in the rinse water at about 1-300 ppm, preferably about 5-150 ppm.
Preferably, care should be taken to insure that the com-positions of the present invention are essentially free of heavy waxes, abrasives, fiberglass, and other fabric incompatibles.
Curable Amine Functional Silicone (CAFS) Curable amine functional silicones can be prepared by known methods. U.S. Pat. Nos. 3,549,590, issued Dec. 22, 1970, and 3,576,779, issued April 27, 1971, both to Holdstock et al., and assi~ned to General Electric Co.; U.S. Pat. Nos. 3,355,424, Brown, issued Nov.

It is important to differentiate the curable amine functional silicones and the noncurable amine functional silicones. The 20curable amine functional silicone molecules have the ability to react one with the other to yield a polymeric elastomer of a much higher molecular weight compared to the original molecule. Thus, "curing" often occurs when two CAFS molecules or polymers react, yielding a polymer of a higher molecular weight. [ ~ SiOH + ~ SiOH
25~~ SiOSi ~ + H20]. A more detailed version of the curing reaction is given below. This "cure" is defined herein as the formation of silicon-oxygen-silicon linkages. The silicon-oxygen-silicon linkage cure is distinguished from polysiloxane bridging reactions between amino groups and carboxyl (or epoxy) groups as 30disclosed in EPA 058,493, Ona et al., published Aug. 25, 1982, (Bulletin 82/34) .
Curable amine functional silicones are commercially avail-able; e.g., Dow Corning Silicone 531 and 536, General Electric SF
1706, SWS Silicones Corp. SWS E-210 are commercially available 35curable amine functional silicones widely marketed for use in hard surface care, such as in auto polishes, where detergent resistance and increased protection are very important.
~00~162 Several fabric care compositions containing curable amine functional silicones are herein disclosed. Several methods of using curable amine functional silicones for wrinkle reduction fabric care are also disclosed.
The CAFS compositions of this invention are used with a suitable liquid carrièr. The term "carrier" as used herein in general means any suitable vehicle that is used to deliver the CAFS and deposit it on the fabric. This invention comprises a liquid starch composition comprising the CAFS plus starch and a suitable carrier.
In a preferred execution, about 0.1% to about 10% by weight of an emulsified curable amine functional silicone is mixed into a suitable commercially available pump spray starch composition.
The result is a spray starch composition that provides an improved wrinkle reduction benefit to fabric sprayed therewith. Suitable commercially available spray starch compositions are based on water and a suitable emulsifier. Care must be taken to use CAFS
emulsifiers which are compatible with the starch and CAFS to avoid deemulsification. A second execution includes a laundry rinse wherein the level of CAFS is present in the rinse water at about 1-300 ppm, preferably about 5-150 ppm.
Preferably, care should be taken to insure that the com-positions of the present invention are essentially free of heavy waxes, abrasives, fiberglass, and other fabric incompatibles.
