Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A yarn finish consisting essentially of a major amount of mineral oil, a minor, viscosity improvement amount of about 0.1 to 15 percent of polyisobutylene having an average viscosity molecular weight of about 8,700-10,500 (Staudinger) and a minor amount of an emulsifier selected from the group consisting ethoxylated isomeric monoalkylphenols substituted with C 3 -C 18 straight or branched chain alkyl groups and containing 1 to 9 ethylene oxide groups per molecule, polyethylene glycol 100 mono-oleate and ethoxylated C 6 -C 18 straight or branched chain alkyl alcohols having 1 to 9 ethylene oxide groups per molecule.
Claim 2
Dependent Claim
97 words
A yarn finish consisting essentially of a major amount of mineral oil, a minor, viscosity improvement amount of about 0.1 to 15 percent of polyisobutylene having an average viscosity molecular weight of about 8,700-10,500 (Staudinger) and a minor amount of an emulsifier selected from the group consisting ethoxylated isomeric monoalkylphenols substituted with C 3 -C 18 straight or branched chain alkyl groups and containing 1 to 9 ethylene oxide groups per molecule, polyethylene glycol 100 mono-oleate and ethoxylated C 6 -C 18 straight or branched chain alkyl alcohols having 1 to 9 ethylene oxide groups per molecule.
Claim 3
Dependent Claim
22 words
The yarn finish of claim 1, consisting essentially of mineral oil, polyethylene glycol 100 mono-oleate and polyisobutylene and also including potassium hydroxide.
Claim 4
Dependent Claim
37 words
The yarn finish of claim 1, also including an anti-static agent selected from the group consisting of substituted hydantoins and ethoxylated C 6 to C 18 phosphate esters having 2 to 9 ethylene oxide groups per molecule.
Claim 5
Dependent Claim
28 words
The yarn finish of claim 3, consisting essentially of mineral oil, polyoxyethylene (3) dodecyl alcohol as an antistatic agent, polyoxyethylene tridecyl phosphate-potassium salt, polyisobutylene and also containing water.
Claim 6
Dependent Claim
52 words
The yarn finish of claim 3, consisting essentially of polyisobutylene, mineral oil, as a boundary lubricant tricesyl phosphate, as a lubricant and antistatic agent dimethyl dihydroxy hydantoin di-oleate polyoxyethylene (2) nonyl phenol, polyoxyethylene (4) nonyl phenol, polyoxyethylene (4) lauryl alcohol, and as an antistatic agent polyoxyethylene (3) potassium salt of tridecyl phosphate.
