Extraction of Fibres from Ashoka (Polyalthia longifolia) for Development of Yarns from PlantWaste Material

October 9, 2020 Science and Technology 0

The present study focused on the development of blended yarns made from pruned ashoka plant-waste material using ashoka bast fibres, the usefulness of which was hardly explored for the purpose. Symmetrical Ashoka (P. longifolia), a perennial herb, exhibits  Pyramidal development of pendulous willowy branches. Via environmental degradation and ultimately, public health, immoral and unthoughtful handling of large quantities of plant waste causes several hazards. Production of plant-waste textile textures can aid in  In addition to providing self-employment through the growth of entrepreneurship in related goods, to address this issue. The Ashoka barks were treated for 2.5 hours at a high temperature ( 100-120 ° C) in 3 percent alkali solution (1:20 MLR). Silicone emulsion (0.5 percent by 0.5%) was used to soften the fibres. Fibre weight) at room temperature. High denier value (76.45) and bundle strength (24.75 g / tex) were observed for ashoka fibres. Ashoka fibre length (59.64 mm) was 9.70 percent greater than wool fibres with moisture content. Two types of yarns-ashoka (100 percent) and ashoka / wool blend (50:50) were hand spun from the extracted ashoka fibres. Compared with 50A:50W blended yarn, higher tenacity (1.09 gf / tex) and breaking force (892.0 gf / denier) of 100 percent ashoka yarn were found. In addition , in the case of 50A:50W, a greater yarn count of 1.77s was observed. Due to the harsh and warm tactile properties that mimic wool, it is concluded that the extracted fibres were ideal for blending with wool. The chemically extracted ashoka fibres were found to be adequate for the production of heavyweight fabrics such as blazers, jackets and stoles for home textiles and clothing applications.
