Claims
- 1. A composition suitable for application to polyester textile, said composition being thermally stable at 375.degree.-405.degree. F., and which imparts soil release properties to the polyester textile, said composition comprising a non-fiber forming polyether-polyester copolymeric material and a thermal stabilizing amount of an antioxidant material which is the butylated reaction product of p-cresol and dicyclopentadiene.
- 2. The composition of claim 1 wherein the antioxidant material has an HPLC tracing as shown in FIG. 1 having a major component with the empirical formula, C.sub.49 H.sub.64 O.sub.3, and represented by the structural formula: ##STR2## wherein each R is a methyl group.
- 3. The composition of claim 1 wherein the antioxidant material is present in an amount of from about 0.5 to about 2.0% by weight based on the weight of copolymeric material.
- 4. The composition of claim 1 wherein the copolymeric material is a polyethylene terephthalate-polyoxyethylene terephthalate copolymer comprising from about 10 to about 50% by weight of ethylene terephthalate repeat units and from about 90 to about 50% by weight of polyoxyethylene terephthalate repeat units derived from polyoxyethylene glycol having an average molecular weight of from about 1000 to about 4000 and wherein the ratio of ethylene terephthalate repeat units to polyoxyethylene terephthalate repeat units is from about 2:1 to about 6:1.
- 5. The composition of claim 4 wherein the copolymeric material comprises the reaction product of ethylene glycol dimethyl terephthalate and polyoxyethylene glycol containing from 1 to about 50 ethylene oxide repeat units.
- 6. The composition of claim 4 wherein the antioxidant material is present in an amount of from about 0.5 to about 2.0 percent by weight based on the weight of the copolymeric material.
- 7. The composition of claim 5 wherein the antioxidant material is present in an amount of from about 0.75 to about 1.5 percent by weight based on the weight of the copolymeric material.
- 8. The composition of claim 1 wherein the copolymeric material comprises the reaction product of ethylene glycol, dimethyl terephthalate and polyoxyethylene glycol.
- 9. The composition of claim 8 wherein the antioxidant material is present in an amount of from about 0.5 to about 2.0 percent by weight based on the weight of the copolymeric material.
- 10. An aqueous emulsion comprising from about 70 to about 90 percent by weight water and the balance the soil release composition of claim 1.
- 11. An aqueous emulsion comprising from about 70 to about 90 percent by weight water and the balance the soil release composition of claim 6.
- 12. An aqueous emulsion comprising from about 70 to about 90 percent by weight water and the balance the soil release composition of claim 7.
- 13. An aqueous emulsion comprising about 85 percent by weight water and the balance the soil release composition of claim 7.
- 14. Polyester textile having applied to or finished thereon the soil release composition defined in claim 1.
- 15. The polyester textile of claim 14 wherein the soil release composition is present thereon in an amount of from about 0.3 to about 1.5% by weight based on the weight of polyester textile.
- 16. The polyester textile of claim 15 wherein the soil release composition is present thereon in an amount of from about 0.5 to about 0.9% by weight based on the weight of polyester textile.
- 17. Polyester textile having applied to or finished thereon from about 0.3 to about 1.5 percent by weight, based on the weight of the polyester textile, of the soil release composition defined in claim 6.
- 18. Polyester textile having applied to or finished thereon from about 0.5 to about 0.9 percent by weight, based on the weight of the polyester textile, of the soil release composition defined in claim 7.
