Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
A process for improving the processability of melt spun yarns of a polymer selected from the group consisting of polyamides and polyesters, which process comprises treating the filaments with an aqeous solution of dispersion containing as the sole essential organic component thereof about 10 to 30 percent by weight of a compound selected from the group consisting of: (a) a water soluble or dispersible condensation product of one mole of a compound having the general formula R--X--H, wherein R is a saturated or unsaturated aliphatic group having from 6 to 18 carbons, and X is oxygen or sulfur; with 7 to 12 moles of ethylene oxide; and (b) a water soluble or dispersible condensation product of one mole of a compound having the general formula R--X--H, wherein R is a saturated or unsaturated aliphatic group having from 6 to 18 carbons, and X is oxygen or sulfur; with from 5 to 20 moles of ethylene oxide and from 2 to 20 moles of propylene oxide.
Claim 2
Dependent Claim
