Title: Low temperature bleaching of cotton using TAED activated peroxide bath Authors: Malik, S K; Das, Manoj Abstract: Low temperature bleaching of cotton fabric using tetraacetylethylenediamine (TAED) in the hydrogen peroxide (H₂O₂) bath has been studied and the most appropriate conditions for this bleaching established. In this technique, in-situ peracetic acid formation takes place via reaction of TAED and H₂O₂ This method gives bleaching comparable to that of the conventional method at relatively low temperature (60°C). The extent of bleaching depends upon the temperature of bleaching, pH, concentration of TAED and treatment time. The loss of strength, process time and alkali required are also found to be less than for the samples bleached in conventional manner. Page(s): 588-590

Classifying fibre attributes of cotton using Kohonen neural networks

Title: Classifying fibre attributes of cotton using Kohonen neural networks Authors: Shanmugam, N; Doke, S S Abstract: Kohonen neural network has been used to classify cotton fibre characteristics, viz. 2.5% span length, bundle strength, short fibre index, uniformity ratio and elongation. Twenty three cottons studied are classified into 3 groups and each group is given range of values for each property. Except fibre elongation, the other properties have distinct range of values for each group. The developed model is found to have a classification rate of 100%, when validation is done for 4 cottons.

Pull-out behaviour of yarn from plain woven jute fabric

Fri, 01 Dec 2006 00:00:00 GMT

Title: Pull-out behaviour of yarn from plain woven jute fabric Authors: Bhattacharya, Salil Kumar B; Chakraborty, Asoke Kumar Abstract: Effects of calendering and bending length on pull-out behaviour of yarns from five different sets of commonly used jute hessian fabrics have been studied. Force required to pull out yarn from the fabric is measured in tensile testing machine. The pull out characteristics of the yarn adjacent to the yarn which has previously been pulled out is also studied. Lesser pull-out force is observed in case of calendered samples, and the load to pull out the adjoining yarn, which is beside the yarn that has already been pulled out, is found to be comparatively much less.

Design and development of illuminated clothing with PMMA for versatile applications

Fri, 01 Dec 2006 00:00:00 GMT

Title: Design and development of illuminated clothing with PMMA for versatile applications Authors: Krishnan, A N Sai; Kumar, L Ashok; Venkatachalam, A Abstract: Polymethyl methacrylate (PMMA), a polymeric optical fibre, has been woven with cotton and polyester in a specific weave pattern to assess the light for light emitting textile application. The illumination of clothing system is primarily influenced by the weave geometry. The sateen weave shows better illumination as compared to twill weave, as the weft bending angle of sateen weave is less due to more weft float in the weave. The opportunities of integration of PMMA material into the clothing system have been investigated comprehensively. Page(s): 577-579
