Multicoloring polyester textile materials with acid dyes
A process is disclosed for making a multicolored polyester material dyed with acid dyes for use as the face yarn of carpets, upholstery and apparel fabrics, which comprises treating a polyester material having an affinity for acid dyes with an aqueous solution or a printing paste of (A) a condensation product of (a) formaldehyde and (b) naphthalenesulfonic acid, phenol, sulfonated phenol, diaryl sulfone, urea, melamine, or dicyandiamide; and (B) a reactive or fiber-reactive compound which contains a chromophore, preferably but not necessarily colorless, and has attached to it a reactive group, which reacts readily with a nitrogen atom of the above-mentioned modified polyester material having an affinity for acid dyes, and then exposing same to steam or dry heat at a temperature between 100 C. and 200 C. for a period of 20 seconds to 20 minutes, thereby imparting to the treated polyester material ability to “resist” acid type dyes, so that the localized regions of the polyester material pre-treated with the above-mentioned impregnation-treatment will now “resist” acid dyestuffs applied later in the dyeing process whereby no coloration or coloration to a much lower depth is produced in the treated regions whereas very strong, bright and uniform coloration is produced due to acid dyes in the localized regions which were not pre-treated; thus resulting in a selective, multicoloration of the polyester material in a predetermined manner. The resulting acid-dyed multicolored polyester material is also described and claimed.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1448-87-9, and how the biochemistry of the body works.Synthetic Route of 1448-87-9
