Abstract:
A spin finish for synthetic fibers which satisfies the following relations (1) and (2):10&lE;T&lE;22â€ƒâ€ƒ(1) 0&lE;Re&lE;0.25â€ƒâ€ƒ(2) where T is the surface tension (mN/m) of the finish after allowing the same to stand at 220Â° C. for 1 hour and Re is the percent residue (% by weight) on heating of the finish after allowing the same to stand at 400Â° C. for 24 hours, andwhich comprises a polyether lubricant (A) and another component (B), said component (B) comprising a constituent (B 1) causing the spin finish after mixing up to show a surface tension of not higher than 22 mN/m after 1 hour of standing at 220Â° C.
