Abstract

1468138 Dyeing synthetic polyamides MONTEDISON SpA 17 June 1975 [18 June 1974 3 Dec 1974] 25825/75 Heading D1B Fabric made from uneven synthetic polyamide fibres are dyed with a dyestuff having the formula where X is a direct link or a methylene group and the group -XCOOH is in the meta or para position to the amino group. The dyeing is preferably carried out in an initially alkaline dyebath containing a buffer, particularly a borate or a phosphate, the pH of the bath being successively reduced from 8.5 to 9.0 to 5 to 5.5 by the addition of an organic acid. Before dyeing, the fabric is preferably scoured. Level, fast, blue shades are obtained.
