Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
98 words
A synthetic polyamide or polyester fiber having deposited thereon a composition consisting essentially of a mixture of (1) a major amount of a polyoxyalkylene ether compound lubricant and (2) a minor effective amount of stabilizer sufficient to prevent oxidative degradation of said lubricant upon exposure to heat in the presence of oxides of nitrogen, said stabilizer a reaction product of one mole of dicyclopentadiene, at least one mole of p-cresol and at least one-half mole of isobutylene wherein the amount of stabilizer ranges from about 0.05 to about 0.45 weight percent based on the weight of the lubricant.
Claim 2
Dependent Claim
98 words
A synthetic polyamide or polyester fiber having deposited thereon a composition consisting essentially of a mixture of (1) a major amount of a polyoxyalkylene ether compound lubricant and (2) a minor effective amount of stabilizer sufficient to prevent oxidative degradation of said lubricant upon exposure to heat in the presence of oxides of nitrogen, said stabilizer a reaction product of one mole of dicyclopentadiene, at least one mole of p-cresol and at least one-half mole of isobutylene wherein the amount of stabilizer ranges from about 0.05 to about 0.45 weight percent based on the weight of the lubricant.
Claim 3
Dependent Claim
34 words
A synthetic polyamide or polyester fiber having deposited thereon the composition of claim 7 wherein the amount of stabilizer ranges from about 0.1 to 0.45 weight percent based on the weight of the lubricant.
Claim 4
Dependent Claim
31 words
A synthetic polyamide or polyester fiber having deposited thereon the composition of claim 7 wherein the amount of stabilizer is about 0.25 weight percent based on the weight of the lubricant.
Claim 5
Dependent Claim
40 words
A synthetic polyamide or polyester fiber having deposited thereon the composition of claim 7 wherein the lubricant is selected from the group consisting of polyoxyalkylene ether polyols, polyalkoxylates of fatty alcohols, polyalkoxylates of fatty acids and alkoxylates of lauryl mercaptan.
Claim 6
Dependent Claim
34 words
A synthetic polyamide or polyester fiber having deposited thereon the composition of claim 7 wherein the amount of lubricant ranges from about 0.2 to 5.0 weight percent based upon the weight of the fiber.
Claim 7
Dependent Claim
34 words
A synthetic polyamide or polyester fiber having deposited thereon the composition of claim 7 wherein the amount of lubricant ranges from about 0.5 to 2.0 weight percent based on the weight of the fibers.
Claim 8
Dependent Claim
100 words
A process for lubricating polyester or polyamide fibers which comprises treating said fibers with a composition consisting essentially of a mixture of a major amount of a polyoxyalkylene ether lubricant and a minor effective amount of stabilizer sufficient to prevent oxidative degradation of said lubricant upon exposure to heat in the presence of oxides of nitrogen, said stabilizer a reaction product of one mole of dicyclopentadiene, at least one mole of p-cresol, and at least one-half mole of isobutylene wherein the amount of stabilizer ranges from about 0.05 to about 0.45 weight percent based on the weight of the lubricant.
Claim 9
Dependent Claim
100 words
A process for lubricating polyester or polyamide fibers which comprises treating said fibers with a composition consisting essentially of a mixture of a major amount of a polyoxyalkylene ether lubricant and a minor effective amount of stabilizer sufficient to prevent oxidative degradation of said lubricant upon exposure to heat in the presence of oxides of nitrogen, said stabilizer a reaction product of one mole of dicyclopentadiene, at least one mole of p-cresol, and at least one-half mole of isobutylene wherein the amount of stabilizer ranges from about 0.05 to about 0.45 weight percent based on the weight of the lubricant.
Claim 10
Dependent Claim
25 words
The process of claim 7 wherein the amount of stabilizer ranges from about 0.1 to 0.45 weight percent based on the weight of the lubricant.
Claim 11
Dependent Claim
22 words
The process of claim 7 wherein the amount of stabilizer is about 0.25 weight percent based on the weight of the lubricant.
Claim 12
Dependent Claim
31 words
The process of claim 7 wherein the lubricant is selected from the group consisting of polyoxyalkylene ether polyols, polyalkoxylates of fatty alcohols, polyalkoxylates of fatty acids and alkoxylates of lauryl mercaptan.
Claim 13
Dependent Claim
25 words
The process of claim 7 wherein the amount of lubricant ranges from about 0.2 to 5.0 weight percent based on the weight of the fiber.
Claim 14
Dependent Claim
25 words
The process of claim 7 wherein the amount of lubricant ranges from about 0.5 to 2.0 weight percent based on the weight of the fiber.
