ABSTRACT:
A finish for synthetic filament to be processed in friction-texturing, which is applicable to various yarns and in a wide range of texturing speed, having been considered as difficult finish application field, such as low-speed friction texturing (with contact heaters), high-speed friction texturing (with non-contact heaters), coarse denier yarns and fine denier yarns, with satisfactory POY package buildup and POY release from packages, minimum fluffs and loops of POY, and with minimum fluffs of DTY and minimum fume and stain on heaters in texturing; and which contains 50 to 85 weight percent of Component A and 10 to 30 weight percent of Component B, having the following structures and a total ranging from 60 to 95 weight percent:Component A having a structure of R1[O(C2H4O)x.(C3H6O)yH]z, wherein R1is a trihydric or tetrahydric alcohol residue, z is an integer of 3 or 4 corresponding to the number of hydroxyl groups in R1, and x and y are integers of 1 or greater attaining a weight ratio of oxytehylene group and oxypropylene group from 90:10 to 60:40 and a molecular weight of the resultant compound from 1000 to 4000; andComponent B having a structure of R2[O(C2H4O)a.(C3H6O)b]COR3, wherein R2is a C4-18monohydric alcohol residue, R3is a C7-17fatty acid residue, a is an integer from 3 to 15, b is an integer from 0 to 12 and the total of a and b ranges from 6 to 15.
