Title: Medullation in Some Native Sheep Wools of Different Fibre Diameters Authors: Singh, V P; Bapna, D L; Patni, P C Abstract: Chokla (48s), Nali (40s) and Sonadi (<36s) breed wools observed under a projection microscope for fibre diameter and percentage of medullated fibres showed that the relationship between fibre diameter and medullation is of an asymptotic nature, resembling the Gompertz curve of the type Y =Ka^bx, where K, a and b are constants.

Title: Effect of NaOH on the Physico-Mechanical Properties of Ramie- Viscose Blended Yarns Authors: Gupta, N P Abstract: Ramie-viscose blended yarns on treatment with 30% (wt/wt) sodium hydroxide solution showed improvement in yarn breaking extension and increase in yarn diameter at a slight expense of yarn strength.

Title: Synthesis of Azodisperse Dyes from Meldrum's Acid for Dyeing Acetate and Other Fibres Authors: Fadda, A A; Yousif, M M; EL-Housini, A M; EL-Housini, M S Abstract: Some 5-arylazo-2,2-dimethyl-1,3-dioxane-4,6-diones have been prepared for use as dyestuffs. The effect of the nature and orientation of substituents in the diazonium component on the colour of azo dyes is discussed. Page(s): 115-117

Rapid Quantitative Measurement of Softness of Barky Root-ends of Jute

Sat, 01 Sep 1984 00:00:00 GMT

Title: Rapid Quantitative Measurement of Softness of Barky Root-ends of Jute Authors: Kundu, A B; Majumdar, S; Ghosh, B S; Bhattacharya, J P Abstract: A simple method for the quantitative measurement of softness of barky root-ends of jute has been developed. The method consists in measuring the impact strength of barky jute by the IJIRA impact strength tester and using this parameter for measuring the degree of softness within certain limits. The relationship between the impact strength and the fibre separation index of barky root-ends of jute has been studied. The impact strength is found to be linearly related both to subjective softness and fibre separation index. The effect of the moisture content of barky root-ends of jute on its impact strength has also been studied. Page(s): 112-114
