Performance of Rabbit Hair Blended Speciality Fibre Yarns

Fri, 01 Jun 1984 00:00:00 GMT

Title: Performance of Rabbit Hair Blended Speciality Fibre Yarns Authors: Patni, P C; Gupta, N P; Arora, R K; Singh, U S Abstract: The fibre properties of rabbit hair, being produced under Indian agro-climatic conditions, are compared with those of Mohair, Cashmere and wool. The performance of rabbit hair and its blends with Hybrid-4 cotton and Avivastra wool on cotton system of processing has also been assessed. It is observed that processing of rabbit hair and its blends on cotton set of machinery is possible with the aid of some suitable antistatic agent. Rabbit hair-cotton blends show high breaking stress, which may be attributed to the closer fineness and length of these fibres. Page(s): 77-79

Performance of Ramie-Polypropylene Blends

Title: Performance of Ramie-Polypropylene Blends Authors: Gupta, N P; Ghosh, S K Abstract: The yarn properties and processing performance of ramie-polypropylene blends on jute rove spinning system have been studied. It is observed that 75/25 ramie-polypropylene blend yarn is stronger than all-ramie or all-Proplon yarn. The use of finer denier Proplon fibre in the blend gives higher yarn strength. Page(s): 74-76

Spectral Studies on Some Azohydrazone Dyes

Fri, 01 Jun 1984 00:00:00 GMT

Title: Spectral Studies on Some Azohydrazone Dyes Authors: El-Kersh, M; El-Sheikh, M Y; Issa, R M; Mansour, E A Abstract: The electronic absorption spectra of some azohydrazone dyes have been studied in organic solvents of varying polarities. The important bands in the IR spectra and signals in the ¹H NMR spectra have been assigned and discussed in terms of substituent effect. Page(s): 70-73

Isolation and Characterization of Two Main Sub-component Proteins of Wool

Fri, 01 Jun 1984 00:00:00 GMT

Title: Isolation and Characterization of Two Main Sub-component Proteins of Wool Authors: Ahmadi, Behzad Abstract: Treatment of wool with aqueous alkaline thioglycollic acid converts 65% of it into soluble fragments, which are insoluble at pH 4.6 and aggregate spontaneously and irreversibly on storage. Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulphate shows that the soluble protein consists mainly of two components. The calibration curves for molecular weights/electrophoretic mobilities are presented. The main components from the plasmolysed wool have molecular weights 44,000 and 58,000 daltons. Their amino acid compositions have been determined; electron microscopy shows that they form fibrous aggregates. Page(s): 64-69
