摘要:
A process for dyeing or printing with reactive dyestuffs a substrate consisting of or comprising cellulosic fibres, comprises using for the fixation of the reactive dyestuffs an aqueous solution of an alkaline system at a pH of from 9 to 13 comprising (a) an alkali metal silicate, and (b) an alkali metal borate, and optionally (c) an alkali metal bicarbonate and/or (d) an alkali metal carbonate.
摘要:
A process for dyeing or printing sized textiles comprising applying to the sized substrate a dyeing liquor or a printing paste which contains, in addition to the dyestuffs(i) a compound or a mixture of compounds selected from compounds having solubilizing, washing, emulsifying, dispersing or dye fixation accelerating properties, and(ii) a textile size or a mixture of textile sizes.
摘要:
1. A process comprisinga) a two liquor process for treating a cellulosic substrate with alkali and applying a dye to the substrate characterized by pad treating the substrate with alkali and dyeing by pad dyeing or printing with a reactive dyestuff without an intermediate washing step; orb) a one liquor process for treating a cellulosic substrate with alkali and a dye characterized in that the substrate is pad treated with alkali and reactive dye.
摘要:
Disclosed is a process for the removal of liquid from an absorbent substrate, comprising passing the substrate through the nip between a pair of rollers, at least one of said rollers having an effective surface of a sponge material, the sponge material having capillary pores, the average diameter of which is less than 1 mm and at least 50% of said pores having a diameter in the range of 0.1 to 0.001 mm, the pressure applied at the nip between said rollers being less than 1 kg per cm roller length.
摘要:
A modified steamer (D) comprising a heatable conduit (5), through which a substrate (S) can be introduced into the steamer (D) so that the substrate (S) can be preheated directly prior to contact with the steam.
