Abstract
An improved, low fuming, thermally stable, texturing finish for a synthetic filamentary material is disclosed comprising 40 to 75 percent of a lubricant, exemplified by pentaerythritol tetrapelargonate; 20 to 50 percent of an emulsifier, exemplified by condensates of castor oil with from about 2 to about 12 moles of ethylene oxide; 2 to 20 percent of an antistat-auxiliary emulsifier, such as a neutralized phosphate ester of an alcohol; and optionally 0 to 2 percent of a thermal stabilizer, exemplified by a condensate of 3-methyl-6-tert-butylphenol with crotonaldehyde. An oil in water emulsion is produced having an oil content of from about 5 to 20 weight percent.
Claims16
A finish composition for synthetic textile filaments comprising:
- a. about 40 to about 75 weight percent of a high molecular weight fatty acid ester lubricant characterized by a weight loss of not more than 25 weight percent when subjected to a temperature of 210.degree. C. for 24 hours;
- b. about 20 to about 50 weight percent of an emulsifier for said lubricant, said emulsifier having a low fuming propensity and being stable against thermal degradation;
- c. about 2 to about 20 weight percent of a neutralized phosphated adduct of an alcohol containing from about 8 to about 18 carbon atoms and about 4 to about 10 moles of ethylene oxide;
- and
- d. 0 to about 2 weight percent of a thermal stabilizer.
A finish composition for synthetic textile filaments comprising:
- a. about 40 to about 75 weight percent of a lubricant selected from the group consisting of glycerol trioleate, refined coconut oil and pentaerythritol tetrapelargonate;
- b. about 20 to about 50 weight percent of an emulsifier selected from the group consisting of adducts of castor oil and hydrogenated castor oils and about 2 to 12 moles of ethylene oxide;
- c. about 2 to about 20 weight percent of a neutralized phosphated adduct of an alcohol containing from about 8 to about 18 carbon atoms and about 4 to about 10 moles of ethylene oxide;
- and
- d. 0 to about 2 weight percent of a thermal stabilizer.
A finish composition for synthetic textile filaments comprising:
- a. about 40 to about 75 weight percent of a lubricant comprising an ester of pentaerythritol and an organic acid selected from the group of acids containing from 4 to 14 carbon atoms, said ester being characterized by a weight loss of not more than 25 weight percent when subjected to a temperature of 210.degree. C. for 24 hours;
- b. about 20 to about 50 weight percent of an emulsifier for said lubricant selected from the group consisting of adducts of castor oil or hydrogenated castor oil and from about 2 to about 12 moles of ethylene oxide;
- c. about 2 to about 20 weight percent of a neutralized phosphated adduct of an alcohol containing from about 8 to about 18 carbon atoms and about 4 to about 10 moles of ethylene oxide;
- and
- d. 0 to about 2 weight percent of a thermal stabilizer.
A low fuming texturing finish for a polyester multifilament yarn comprising from about 40 to about 75 weight percent pentaerythritol tetrapelargonate;
- about 20 to about 50 weight percent of an adduct of a castor oil and from about 2 to about 12 moles of ethylene oxide;
- and from about 2 to about 20 weight percent of a neutralized phosphated adduct of an alcohol and 4 to 10 moles of ethylene oxide.
A textile finish composition comprising:
- 60 percent of pentaerythritol tetrapelargonate;
- 30 percent of an adduct of five moles of ethylene oxide and one mole of hydrogenated castor oil;
- 10 percent of an adduct of five moles of ethylene oxide and a mixture of C.sub.12 and C.sub.15 alcohols, phosphated and neutralized with potassium hydroxide;
- and 1 percent of a condensate of three moles of 3-methyl-6-tert-butylphenol with one mole of crotonaldehyde.
