Abstract
1275826 Dyeing polyamides BADISCHE ANILIN- & SODA-FABRIK AG 11 Sept 1969 [12 Sept 1968] 44823/69 Heading C3R Polyamides are mass dyed or spin dyed with a 1,4-diaminoanthraquinone sulphonic acid dye or a salt thereof, where R is H, C 1-3 alkyl, or substituted or unsubstituted phenyl. Where "sulpho" means -SO 3 H or salt thereof, e.g. with an alkali or alkaline-earth metal or NH 4 , X is sulpho, H, halogen, or C 1-2 alkyl. R<SP>1</SP> is H, C 1-2 alkyl or cycloalkyl, aralkyl, or substituted or unsubstituted phenyl, phenyl bearing sulpho group(s), or sulphonylaryl. Z and Z<SP>1</SP> are H, halogen, or OH. At least one of R and X is H. If X is not sulpho, then R<SP>1</SP> contains one or more sulpho groups. Preferably R, Z, and Z<SP>1</SP> are H, and X is sulpho, Br, or Cl. The substituents borne by R or R<SP>1</SP> may be F, Cl, C 1-3 alkyl, C 1-2 alkoxyl, or substituted or unsubstituted amino. The polyamide may be nylon 6 or 6,6. Nylon granules may be dusted with 0À2-0À3% dye and melt extruded to a filament; or nylon granules which may have edge-length 2-3 mm. may be melted with 0À3% TiO 2 , dyed, at 98-99‹ C. with 0À5% dye with liquor-ratio 1 :1; acetic acid may optionally be added and dyeing continued. After cooling to 30-40‹ C., the granules are centrifuged and vacuum-dried at 80‹ C., spin-extruded to filaments, and stretched. Specifications 1,208,402 and 1,273,675 are referred to.
