Effect of counterions and ureas on adsorption of direct dye on cellulose
Effect of counterions and ureas on adsorption of direct dye on cellulose. Nango, Mamoru; Ohta, Shozo; Kimura, Hirobumi; Shinmen, Yuji; Kuroki, Nobuhiko (Coll. Eng., Univ. Osaka Prefect., Sakai 591, Japan). Text. Res. J., 54(9), 598-602 (English) 1984. CODEN: TRJOA9. ISSN: 0040-5175. DOCUMENT TYPE: Journal CA Section: 40 (Textiles) The adsorption of C.I. Direct Yellow 12 (I) [2870-32-8], C.I. Direct Blue 15 [2429-74-5], and C.I. Direct Red 2 [992-59-6] on cotton increased in the presence of counterions in the following order: Cs+ > NH4+ > K+ > Na+. In the presence of electrolytes I adsorption increased in the order CsCl > KCl > NH4Cl > NaCl. The adsorption of I on cotton in the presence of NaCl decreased at 25-35° in presence of urea [57-13-6] and increased at 55-90° in the presence of urea. At 25° I adsorption decreased with the addn. of tetramethylurea [632-22-4]. and urea.
Effect of the conditions of dyeing of cellulosic textile materials on their air permeability
Effect of the conditions of dyeing of cellulosic textile materials on their air permeability. Muresan, Augustin; Muresan, Rodica; Butnaru, Romen (Inst. Politeh., Iasi, Rom.). Ind. Usoara: Text., Tricotaje, Confectii Text., 35(6), 263-6 (Romanian) 1984. CODEN: IUSAAE. DOCUMENT TYPE: Journal CA Section: 40 (Textiles) The effect of concn. of dye in the dyeing bath and the relative humidity during dyeing on the air permeability of cotton and rayon fabrics dyed by Direct Red 4 A (I) [992-59-6] and Reactive Red MB (II) [94586-74-0] and the effect of alkali concn. in the dye bath on the air permeability of the fabrics dyed by II were discussed. The max. air permeability for the dyed cotton fabrics was obsd. when dyeing baths contained 3 and 5% I and II, resp., and the corresponding values for the rayon fabrics were 2-3 and <5 or >6%, resp.
