| titleOfInvention | Phenolic stain-resists |
| abstract | A stain-resist agent for polyamides fibers, its preparation and use are disclosed. The stain-resist agent is the condensation product of a phenolic of which at least 67 weight percent is bis-hydroxyphenylsulfone and the remainder p-cresol, p-phenolsulfonic acid or methyl-p-hydroxybenzoate, with from about 0.4 to 2.3 moles per mole of the phenolic of a mercapto-substituted carboxylic acid which is mercaptosuccinic acid, mercaptoacetic acid or mercaptopropionic acid and about 1.4 to about 3.7 moles per mole of mercapto-substituted carboxylic acid, of formaldehyde and sufficient base to neutralize all of the mercapto-substituted carboxylic acid groups and part but not all of the phenolic groups. The product contains about 3 to about 6 phenolic moieties with a molecular weight of 1500 to 2500 being preferred. Generally the reactron is carried out at reflux temperature (100° to 103 °C) for a period of 24 to 72 hours. Generally the stain-resist is applied to the polyamide fibers at a pH of 1.8 to 5.0 for a period of 1 to 60 minutes. |
