Abstract
A method for applying a low soil finish to spun synthetic textile fibers comprising applying to the spun fibers a low soil finish composition containing a dry, waxy solid component which comprises one or more of the following: A) a bisamide of the formula ##STR1## wherein R and R" can be the same or different and are straight or branched alkyl groups having from 7 to 19 carbon atoms, R' is a C.sub.2 -C.sub.4 linear alkyl group, and x is an integer of from 0 to 5; B) a block copolymer of ethylene oxide and propylene oxide; pa C) the reaction product of a C.sub.8-20 saturated fatty alcohol, a C.sub.8-20 saturated fatty amine, or a phenol, with from 2 to 250 moles of ethylene oxide, and D) a C.sub.8-22 fatty acid ester.
Claims14
A method for applying a low soil secondary finish to synthetic fibers comprising treating spun fibers with a coating effective quantity of a composition comprising a dry waxy component solid at room temperature selected from at least one compound from the group consisting of
- A) a bisamide of the formula ##STR5## wherein R and R" can be the same or different and are straight or branched alkyl groups having from 7 to 19 carbon atoms, R' is a C.sub.2 -C.sub.4 linear alkyl group, and x is an integer of from 0 to 5;
- B) a block copolymer of ethylene oxide and propylene oxide;
- C) the reaction product of a C.sub.8-30 saturated fatty amine or a phenol with from 2 to 250 moles of ethylene oxide, and
- D) a C.sub.8-22 fatty acid ester;
- provided that the composition cannot consist of a combination of DETA bisstearamide, POE (30) stearyl alcohol, and POE (40) cetyl/stearyl alcohol in a molar ratio of 17:2.25:0.75 as the dry, waxy component.
A method for apply a low soil secondary finish to synthetic fibers comprising treating spun fibers with a coating effective quantity of a composition comprising a dry waxy component solid at room temperature which is a bisamide of the formula ##STR6## wherein R and R" can be the same or different and are straight or branched alkyl groups having from 7 to 19 carbon atoms. R' is a C.sub.2 -C.sub.4 linear alkyl group, and x is an integer of from 0 to 5;
- provided that the composition cannot consist of a combination of DETA bisstearamide, POE (30) stearyl alcohol, and POE (40) cetyl/stearyl alcohol in a molar ratio of 17:2.25:0.75 as the dry, waxy component.
