Patent number: 4701182Abstract: Hitherto there has been no practical pad-dwell process for wool piece goods which could be carried out without using large amounts of textile assistants.

Patent number: 4640691Abstract: Vinylsulfonyl dyes, if padded from acidic liquors, produce on wool merely dyeings having a poor yield and only moderate fastness properties if the pad-beam method is used. It has been found according to the invention that padding from weakly alkaline liquor (pH 7-9) with sodium bicarbonate as fixing alkali and subsequent batching (6-24 hours) of the material produces good coloristic results especially on wools with a low-felting or non-felting finish.Type: GrantFiled: January 28, 1986Date of Patent: February 3, 1987Assignee: Hoechst AktiengesellschaftInventors: Wolfgang Richter, Bernd Durl

Patent number: 4636223Abstract: When silk fabrics, pre-treated with swelling agents, are printed by heat transfer techniques, the fabric will yellow. The invention eliminates yellowing by pre-treating said silk fabrics with a liquid or solid impregnating agent, dissolved or dispersed in water, then drying the fabric, and adding before, during or after the pre-treating an optical brightening agent of the type normally used for polyester.The impregnating agent can alternatively be applied to the fabric in a water-free condition before or during dyestuff transfer, and an optical brightener may be added.It is further contemplated to use easily migrating dyestuffs which are transferred to the fabric at relatively very low temperatures, and to avoid dyestuff migration by pre-treating the silk fabric with solid impregnating agents.All these techniques produce deep and brilliant shades; the prints have excellent fastnesses.Type: GrantFiled: April 4, 1985Date of Patent: January 13, 1987Assignee: Sicpa Holding S.A.Inventors: Wolfgang Mehl, Albert Amon

Patent number: 4622045Abstract: The invention provides a process for dyeing a textile substrate comprising wool fibres, which process comprises bringing the substrate into contact with an aqueous dyebath containing an acid dyestuff or a mixture of acid dyestuffs having(a) a build-up power on wool of from 90 to 98% at pH 4.5; together with(b) a migrating ability on wool of from 25 to 40%, at pH 4.5;(a) and (b) being determined under specific conditions, in the presence of a levelling agent which is the alkoxylation product of an amine substituted by a fatty saturated or unsaturated residue, the aqueous dyebath containing a mixture of acid dyestuffs when the substrate is a wool/synthetic polyamide fibre blend.These dyestuffs give level, fast and reproducible dyeings of a high quality.Type: GrantFiled: September 28, 1984Date of Patent: November 11, 1986Assignee: Sandoz Ltd.Inventors: Josef Frauenknecht, Karl Zeller
