Abstract
Fiber finish compositions comprising a major amount of a polyoxyalkylene glycol or fatty acid ester lubricant and a minor amount of an oxidative and thermal stabilizer system therefor comprising a blend of a substituted 1,3,5-triazine and a multi-functional hindered phenolic compound, a process for the application thereof and the coated fibers resulting therefrom.
Claims14
A fiber treating composition comprising
- (A) a lubricant selected from the group consisting of polyoxyalkylene ether polyols, alkoxylates of fatty acids, and alkoxylates of fatty acids blended with unsaturated vegetable oils;
- and
- (B) an effective stabilizing amount of a mixture of 2,4-bis(n-octylthio)-6-(4-hydroxy-3,5-di-tert.butylanilino)-1,3,5-triazine and a multi-functional hindered phenol corresponding to the formulae:
- ##STR8## wherein R and R.sub.1 independently are C.sub.1 -C.sub.6 alkyl, x is 0 to 6, y and z independently are 2 to 20 and R.sub.2 is hydrogen hydroxy or ##STR9## wherein n is the number of repeating units ##STR10## said triazine and said phenol being present in said mixture in a weight ratio of from 1:1 to 1:9.
