Organic cotton is grown without pesticides and insecticides and seeds are not genetically modified. India is still the largest producer of organic cotton in the world, accounting for two-third of the global organic cotton production. Textile in the form of fibre, yarn, fabric, garment and fashion accessory is of at most adorable substrate. It is but true that cotton as Kapas (cotton wool with seeds) has very little value as raw goods but the post harvest processes shall definitely fetch better (premium) price. Two varieties of cottons selected for the study were DHH - 11 and DHB - 915. The efficiency of ginning in conversion of Kapas into lint was 49 per cent and remaining 51 per cent was wastage. The efficiency of spinning was 64 per cent and wastage was 36 per cent. Thrash, handling during spinning, wastage during mechanical processing were the main causes for wastage. The quantity of yarn obtained from 10.66 Q of Kapas was 3.36 q almost 1/3 of the total weight; but the returns were 5.82 folds. The calculated profit from Kapas to finished cloth was 29.60 per cent.Keywords

Polyester is the hydrophobic synthetic fibre which lacks surface reactivity thus, leads to accumulation of electrostatic charge and poor fabric comfort. This undesirable property can be overcome through transforming the polyester into hydrophilic by modifying the surface topography. Oxygen plasma is the dry, eco-friendly finishing technique and effective means to alter the surface morphology of fibre in order to induce hydrophilicity in polyester by adding more numbers of polar groups. Surface structure was assessed by SEM (Scanning Electron Microscope) and the wettability studied by wicking action. The changes in structural, performance, durable properties after plasma treatment and on subsequent washes were basically due to etching action of plasma.Keywords

Cotton and polyester fabrics were subjected to Atmospheric Pressure Plasma (APP) followed by Flame Retardant (FR) treatment using dielectric barrier discharge plasma with He-O2 gas mixture by padding mangle; dried and cured on hot air stenter. The main aim of the study was to assess the effect of plasma-FR treatment on fibre topography, structural and functional properties.Surface topography of treated test samples assessed under SEM and revealed about surface erosion of both the fibres through pictorial presentation. Positive enhancement not only in structural properties of FR finished fabrics viz., cloth count, thickness, GSM and dimensional stability but also the flame retardancy of cotton and polyester were noticed. Further, the qualitative improvements induced due to plasma-FR treatment were found to be sustainable on multiple washes. Thus, it is concluded that APP as a pre-treatment increases the fixation of FR agent into the etched fibre surface and induces sustainability of finish at greater levels.Keywords
