Beschreibung
Zusammenfassung:	PURPOSE:To provide the titled lubricant which has excellent bulkiness-imparting properties and antistatic properties and can prevent fiber dust from being formed in a card stage, by incorporating an alkali metal salt of a specified alkyl phosphate ester and a polyether. CONSTITUTION:50-70wt% alkali metal salt of an alkyl phosphate ester in which alkyl groups contain an average of 14 to 18 carbon atoms such as potassium salt of myristyl phosphate, is blended with 50-30wt% block polyether having an average MW of 1,000-4,000 obtd. by copolymerizing ethylene oxide with propylene oxide, to obtain a lubricant for polyester fiber wadding. Usually, this lubricant is used as an aq. emulsion by diluting it with water. This emulsion is sprayed on polyester fiber in an orientation stage to deposit 0.1- 0.4wt% lubricant on the fiber.
