Tribology of Textile Materials

Fri, 01 Sep 2000 00:00:00 GMT

Title: Tribology of Textile Materials Authors: Ramkumar, S S Abstract: Recently, there has been an upsurge in research interests on the frictional properties of materials. This has been partly due to the availability of tools to understand the structure and properties of materials at micro and nano levels¹. However, in the case of textile materials, currently there is a renewed interest at the macro level due to its research potential and lack of understanding at this level. The main objective of this brief communication is to clearly understand the method and the unit to characterize the friction al properties of textiles. Page(s): 238

Structure-property relationship of fibre, yarn and fabric with special reference to low-stress mechanical properties and hand value of fabric

Fri, 01 Sep 2000 00:00:00 GMT

Title: Structure-property relationship of fibre, yarn and fabric with special reference to low-stress mechanical properties and hand value of fabric Authors: Beheraa, B K; Shakyawar, D B Abstract: An attempt has been made to review the work done so far in understanding the influence of wool fibre, yam and fabric structures and their properties on low-stress mechanical properties and hand value of fabric. The role of finishing treatments and application of softeners on low-stress mechanical properties has also been reviewed. Finally, the need of establishing a vertical relationship between fibre and garment is suggested. Page(s): 232-237

Effect of oxygen plasma on woollen fabric properties

Title: Effect of oxygen plasma on woollen fabric properties Authors: Shekar, R Indu; Bajpai, S K Abstract: Woollen fabric was subjected to oxygen plasma treatment separately at 50W and 100W power and low pressure using glow discharge. The treated samples were tested for shrinkage, weight loss and wicking and dyed with Nylomine Acid Red B-5B. The colour fastness and perspiration tests were also carried out. The plasma-treated samples exhibited excellent wicking properties and significantly reduced shrinkage. The sample treated at higher power settings showed more weight loss. The dyed samples showed satisfactory fastness properties. Page(s): 229-231

Effect of pressure between roller and knife edge on the quality of double roller ginned cottons

Title: Effect of pressure between roller and knife edge on the quality of double roller ginned cottons Authors: Jadhav, S B; Vancheswaran, S; Vizia, N C Abstract: A double roller gin was set to work at three different pressures (67, 133 and 200 kg) between the rollers and the fixed knife edges to process ten varieties of cotton, and the effect of pressure on various quality parameters of ginned lint studied. It is observed that the higher pressures decrease the average fibre length and increase the ginning percentage, short fibre content, nep count and seed coat fragments. Page(s): 225-228
