Abstract
A processing agent for synthetic fibers contains a lubricant, a functional improvement agent and an emulsifier, each containing a specified kinds of components by a specified amount and also by a specified total amount so as to have improved characteristics of preventing occurrence of fluffs, yard breaking and uneven dyeing when applied to synthetic fibers at a specified rate.
Claims2
A processing agent for synthetic fibers, said processing agent consists of 50-90 weight % of a lubricant, 1-30 weight % of a functional improvement agent and 2-30 weight % of an emulsifier, wherein said lubricant is selected from the group consisting of polyether compounds with average molecular weight of 700-10000, aliphatic ester compounds with 17-60 carbon atoms and mineral oils having a viscosity of 1×10−6-5×10−5 m2/s at 30° C., said functional improvement agent is shown by Formula 1, wherein Formula 1 is:
- where R1, R2, R3 and R4 are each hydrogen atom or aliphatic hydrocarbon group with 1-6 carbon atoms, two or less thereof being hydrogen atom at the same time, the total number of carbon atoms in R1-R4 in Formula 1 being 2-14;
- R5 and R6 are each hydrogen atom;
- and A1 and A2 are each residual group obtainable by removing hydrogen atoms from all hydroxyl groups of (poly)alkyleneglycol having (poly)oxyalkylene group formed with a total of 1-30 oxyalkylene units with 2-4 carbon atoms.
