Analysis on the Yarn and Fabric Characteristics of Chiengora Fibers from Hairs of Lhasa Apso Breed and its Blends in Comparison with Wool and its Blends. Part I – Yarn Characteristics

ABSTRACT

This work is focused on utilizing the unconventional chiengora fibers for textile applications. In this research, the chiengora fibers from lhasa apso are made into yarns in association with polyester and acrylic. Their yarn characteristics are evaluated in comparison with wool yarn and its blends that are produced and the results are presented. Yarns of 16 blend proportions are produced using rotor spinning machine. During yarn spinning, fiber loss in carding and sliver breakages is higher for 100% chiengora yarns spinning. The actual blend proportions matches with mixing blend proportions closely when the chiengora content (25%) is least in the blended yarns. The count of all these yarns are maintained as 14 s Ne. It is observed that all the yarn properties deteriorate with increase in chiengora and wool content. ANOVA shows that there is significant difference between different blend proportions of each group of yarn in all the properties evaluated. The yarn characteristics of chiengora fibers are observed to be similar to wool. However, the Yarn Quality Index (YQI) of 75/25 and 50/50 lhasa apso polyester were found to be better indicating their suitability for further usage in fabrics.

摘要

生态农业和有机肥在使用合成肥料和农药且易于克服的情况下得到了及时的普及和要求. 本文介绍了大麻的有机耕作 (Cannabis sativa L.), 并研究了一种创新的有机肥料-桑蚕 (Bombyx mori L.) 繁殖废料. 这种昆虫繁殖是一种廉价的废物来源, 对植物产量产生了非常积极的影响. 到目前为止还没有对大麻进行过这样的试验. 本研究制备了3个重复罐: 用蚕肥15mg∙ha-1, 30毫克∙ha-1和不施肥的盆栽（对照）. 测定了总产量、秸秆产量和种子产量. 此外, 还对蚕渣, 土壤和麻料的化学成分进行了测定. 施用量为30mg的蚕粪施肥效果最好∙ha-1型.
