摘要:
The use of polymeric etheramines (P) as aftertreatment agents for dyeings or colour prints obtained with at least one water soluble dye (F) on textile fibrous material (T), especially for improving their fastness to chlorine, the process for producing the aftertreated dyeings and colour prints, and particular aftertreatment compositions, as defined in the Claims.
摘要:
The invention relates to a process for dyeing synthetic or natural polyamide fibers with anionic dyestuffs, comprising (i) bringing the polyamide fibers into contact with an aqueous dyeing liquor which contains in addition to one or more dyestuffs a cationic dyeing assistant having affinity for anionic polyamide dyestuffs, and dyeing the polyamide fibers at a temperature of from 60.degree. to 105.degree. C., and (ii) adding an anionic dyeing assistant to the dyeing liquor 15 to 60 minutes after reaching the dyeing temperature, to complete the dye exhaustion. Surface and fibre level dyeings with a good dye penetration are thus obtained.

摘要:
This invention is directed to treatments for dyed textile goods that will improve their fastness properties. More particularly, the invention is directed to certain fixatives that, when placed on the dyed textile, allow the dye to be permanently or substantially permanently affixed to the fabric. The dye-reactive fixative comprises a water-soluble or water-dispersible polymer or oligomer having reactive groups that react with a dye on a dyed web to affix the dye to the web.
摘要:
A method for exhaust dyeing a polyester or polyester blend textile article with a disperse dye is provided whereby the article is first treated with an aliphatic amine to reduce the tensile strength of the polyester fibers, followed by dyeing the fabric in a bath containing from 1.0 to 3.0 weight percent based on the weight of the fabric, of a compound selected from the group consisting of:(a) C.sub.8 -C.sub.16 aliphatic fatty acid ethoxylates having from 5 to 15 ethylene oxide residues;(b) C.sub.8 -C.sub.16 alcohol ethoxylates having from 5 to 15 ethylene oxide residues; and(c) C.sub.8 -C.sub.16 aliphatic amine ethoxylates having from 5 to 15 ethylene oxide residues,to achieve a spot free, level dyed fabric, with reduced pilling tendencies.
