Abstract
Abstract A spin finish composition for polyamide yarn to be processed into plied, bulked, continuous filament carpet yarn, comprising coconut oil, polyoxyethylene hydrogenated castor oil and the potassium salt of polyoxyethylene tridecyl alcohol phosphate. This finish improves processing of the yarn at high temperature, as by steam jet texturing, and prevents excessive tension build-up during subsequent cabling operations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
A spin finish for polyamide yarn to be processed at high temperature and high tension into plied, bulked, continuous filament carpet yarn, said finish being an oil in water emulsion of about 10 to 20 percent by weight of said oil portion, said oil portion consisting essentially of from about 55 to 65 percent by weight of coconut oil, about 20 to 35 percent by weight of polyoxyethylene hydrogenated castor oil, and about 7 to 15 percent by weight of potassium salt of polyoxyethylene tridecyl phosphate.
Claim 2
Dependent Claim
86 words
A spin finish for polyamide yarn to be processed at high temperature and high tension into plied, bulked, continuous filament carpet yarn, said finish being an oil in water emulsion of about 10 to 20 percent by weight of said oil portion, said oil portion consisting essentially of from about 55 to 65 percent by weight of coconut oil, about 20 to 35 percent by weight of polyoxyethylene hydrogenated castor oil, and about 7 to 15 percent by weight of potassium salt of polyoxyethylene tridecyl phosphate.
Claim 3
Dependent Claim
14 words
The spin finish of claim 1 wherein the coconut oil is refined coconut glyceride.
Claim 4
Dependent Claim
27 words
The spin finish of claim 1 wherein the ethoxylated hydrogenated castor oil contains about 14 to 18 moles of ethylene oxide per mole of hydrogenated castor oil.
Claim 5
Dependent Claim
29 words
The spin finish of claim 1 wherein the ethoxylated tridecyl phosphate, potassium salt, contains about 4 to 6 moles of ethylene oxide per mole of tridecyl phosphate, potassium salt.
Claim 6
Dependent Claim
140 words
In a process for production of plied, bulked, continuous filament polyamide carpet yarn from steam textured polyamide yarn, wherein a first single end of said steam textured polyamide yarn is ballooned about and plied with a like single end of yarn while both are under tension and advancing at a common linear speed, the improvement wherein the yarn is treated during spinning with 0.5 to 1.2 percent by weight of said yarn of a spin finish, said finish being an oil in water emulsion of about 10 to 20 percent by weight of said oil portion, said oil portion consisting essentially of from about 55 to 65 percent by weight of coconut oil, about 20 to 35 percent by weight of polyoxyethylene hydrogenated castor oil, and about 7 to 15 percent by weight of potassium salt of polyoxyethylene tridecyl phosphate.
Claim 7
Dependent Claim
140 words
In a process for production of plied, bulked, continuous filament polyamide carpet yarn from steam textured polyamide yarn, wherein a first single end of said steam textured polyamide yarn is ballooned about and plied with a like single end of yarn while both are under tension and advancing at a common linear speed, the improvement wherein the yarn is treated during spinning with 0.5 to 1.2 percent by weight of said yarn of a spin finish, said finish being an oil in water emulsion of about 10 to 20 percent by weight of said oil portion, said oil portion consisting essentially of from about 55 to 65 percent by weight of coconut oil, about 20 to 35 percent by weight of polyoxyethylene hydrogenated castor oil, and about 7 to 15 percent by weight of potassium salt of polyoxyethylene tridecyl phosphate.
Claim 8
Dependent Claim
13 words
The process of claim 5 wherein the coconut oil is refined coconut glyceride.
Claim 9
Dependent Claim
26 words
The process of claim 5 wherein the ethoxylated hydrogenated castor oil contains about 14 to 18 moles of ethylene oxide per mole of hydrogenated castor oil.
Claim 10
Dependent Claim
29 words
The spin finish of claim 5 wherein the ethoxylated tridecyl phosphate, potassium salt, contains about 4 to 6 moles of ethylene oxide per mole of tridecyl phosphate, potassium salt.
