Comparison of Hook Extent Distribution of Fibres in Feed Sliver and Rotor Fibre Ring

Thu, 01 Dec 1988 00:00:00 GMT

Title: Comparison of Hook Extent Distribution of Fibres in Feed Sliver and Rotor Fibre Ring Authors: Chattopadhyay, R Abstract: The pattern of hook extent distribution in rotor fibre ring has been found to be highly positively skewed having a prominent peak between 2-4 mm. The pattern remains unaffected by the direction of sliver feed and the number of times it has undergone drawing operation. Page(s): 218-219

Thu, 01 Dec 1988 00:00:00 GMT

Title: Effect of Reeling Bath Temperature on the Weavability of Silk Yarn into Fabric Authors: Manna, S S; Sengupta, D; Rao, G Subba; Das, B C Abstract: The effect of reeling bath temperature on the weavability of silk yarn into fabric has been studied and a reeling bath temperature of 85°C is recommended as the best for weavability of silk yarn.

Synthesis and Dyeing Characteristics of 5-(4-Arylazophenyl) azo-3-cyano- 4-methyl-6-hydroxy-2-pyridones

Thu, 01 Dec 1988 00:00:00 GMT

Title: Synthesis and Dyeing Characteristics of 5-(4-Arylazophenyl) azo-3-cyano- 4-methyl-6-hydroxy-2-pyridones Authors: Kanhere, J M; Rangnekar, D W Abstract: Fourteen bisazo disperse dyes, 5-(4-arylazophenyl) azo-3-cyano-4-methyl-6-hydroxy-2-pyridones, were prepared and their dyeing performance on polyester was assessed. The dyeings on polyester had yellow, orange, brown and red shades with good pick-up, good to excellent light fastness and excellent sublimation fastness. Page(s): 213-215

Application of Ultrasonics in Dyeing of Cotton Fabrics with Direct Dyes: Part II-Diffusion Kinetics

Thu, 01 Dec 1988 00:00:00 GMT

Title: Application of Ultrasonics in Dyeing of Cotton Fabrics with Direct Dyes: Part II-Diffusion Kinetics Authors: Thakore, K A Abstract: The diffusion coefficients of two direct dyes into cotton fabric have been determined experimentally from the rate of dyeing curves under the influence of kinetic variables. The apparent increase in the diffusion coefficients on application of ultrasonic field is ascribed to cavitation. Diffusion coefficients vary with the intensity of waves. SEM studies and breaking strength tests revealed that fabrics insonated for experimental dyeing time remain largely intact. Page(s): 208-212
