Development and processing of lyocell

2004-12-01T00:00:00Z

Title: Development and processing of lyocell Authors: Chavan, R B; Patra, A K Abstract: An account of Iyocell, covering the hindsight of its development and available brands has been reported. This wonder fibre surpasses all other cellulosic fibres in terms of properties, aesthetics and. quite importantly. ecology in manufacturing. Among the various names with which Iyocell is available. Tencel and Tencel A 100 are the prominent and widely used. Besides dealing with the various attributes of Iyocell, the options for wet treatment of the fibre with reference to steps of processing, suitability of dyes and process parameters have also been addressed.

Pilling of polyester/wool blends

2004-12-01T00:00:00Z

Title: Pilling of polyester/wool blends Authors: Long, Li; Wei, Zhou Abstract: The pilling of a series of worsted fabrics made- from wool/polyester fibres has been tested using circular locus pill tester and the mechanism of pilling studied. The process and the mechanism of pilling have been studied through the observation of fibre morphology on fabric surface by using scanning electron microscope. It is observed that the conditions of test, structure of yam, wool content and property of polyester fibres affect the pilling of worsted fabrics. Page(s): 480-482

Effect of preparatory process on quality of fibres in milange yarn production

2004-12-01T00:00:00Z

Title: Effect of preparatory process on quality of fibres in milange yarn production Authors: Selvan, M Tamil; Raghunathan, K Abstract: The effects of fibre dyeing, drying, opening and carding during milange yarn preparation on length and tensile properties of fibres have been studied using three different varieties of Indian cottons, namely S6, DCH32 and MCU5. It is observed that the dyeing, drying, opening and carding affect the fibre quality; the effect however varies with the fibre variety. Page(s): 477-479

Extraction and identification of colour components from the barks of Mimusops elengi and Terminalia arjuna and evaluation of their dyeing characteristics on wool

Title: Extraction and identification of colour components from the barks of Mimusops elengi and Terminalia arjuna and evaluation of their dyeing characteristics on wool Authors: Bhuyan, R; Saikia, C N; Das, K K Abstract: Dyes have been extracted from the barks of Mimusops elengi and Terminalia arjuna and the chemical constituents of the colour components responsible for dyeing identified. The dyeing behaviour of these colour components on wool has also been evaluated. Depending on the concentrations of dye (1-6%) in the dye bath, the dye absorption on the fibre varies from 21 .943% to 27.462% and from 5.184% to 10.787% respectively for the dyes extracted from M. elengi and T. arjuna. The colour components isolated from the barks of the two plant varieties mainly contain flavonoid moiety. The dyed and post-mordanted wool exhibits better fastness properties and therefore these dyes might be an alternative to synthetic dyes. Page(s): 470-476
