Treatment of polyamide materials with partial fluoroesters or fluorothioesters of maleic acid polymers and sulfonated aromatic condensates |
摘要 |
The present invention comprises a process for providing soil resistance and resistance to staining by acid dyes to fibers and textiles by simultaneous or sequential application of a sulfonated phenol-formaldehyde condensation product and partial fluoroesters or fluorothioesters formed from copolymers of maleic anhydride and perfluoroalkyl alcohols or perfluoroalkyl thiols.
