Coir fibre is a non-conventional fibre extracted from the husk of coconut fruit and is abundantly available in tropical countries. Coir yarn is produced in the decentralised cottage industry. Increase in the demand for the coir fibre yarns for value-added applications has forced the coir yarn manufacturers to improve the existing coir spinning machine in different ways. In this study, the working principle of the existing coir spinning machine has been studied from the perspective of further improvements in production rate, yarn quality and spinning performance. Modifications have been made in the existing coir spinning machine in fibre feeding, opening and cleaning. There is improvement in the production rate of up to 20% with significant improvements in the yarn quality and spinning performance.
Garment cling fit is a proximal fit that emphasizes close clinging contour lines of the apparel maintained by it on the human body in regular postures and while performing primary movements. To understand the nature of interface between ease reduction treatments and structural constructs, three-dimensional (3D) modeling of human body using body mapping concept and ease reduction treatment’s role in explaining the garment strain patterns in cling fit conditions were investigated. We report the impact of ease reduction treatment that defines the proportions and measurements of the cling fit pattern with reference to human body surface profile.
