ABSTRACT

The wool of Dumba fleece is an admixture of fine wool and coarse hairy fibers. (Tomer, 2018 Tomer, A. K., 2018. Performance appraisal of Dumba (Fat tail/rump) Sheep P68. Annual report 2017-18, ICAR-Central Sheep and Wool Research Institute, Avikanagar.Tonk (Raj.) India [Google Scholar]) The use of the slow speed carding machinerecovers fine wool fibers accounts 19.6% of fleece weight. The mean fiber diameter and medullation of recovered wool are 23.2 µm and 14.0%, respectively. The recovered wool fibers are able to spin into yarn of 20.7 Nm with the use of carrier fiber only. Nylon staple fiber of 2.5 denier and fine crossbred wool are mixed to spin yarn on semi-worsted spinning system. The fabric was woven with prepared yarn on handloom. The fabric has found the harsh feel due to available medullated fibers even after the removal of hairy fibers. The surface properties of the fabric were improved through enzyme treatment followed by softener application. The fabrics were evaluated for thermal insulation and surface smoothness. The thermal insulation value is found to improve from 2.03 to 2.18 for enzyme and softener treated fabric, respectively. The chemical treatment improves the fabric smoothness/softness, i.e, frictional properties viz. dynamic and static frictional resistance by 12.4% and 7.0%, respectively.

摘要

Dumba 羊毛的羊毛是细羊毛和粗毛纤维的混合物。（托默，2018 托默，AK，2018 年。Dumba（肥尾/臀部）绵羊 P68 的性能评估。2017-18 年度报告，ICAR-中央绵羊和羊毛研究所，Avikanagar.Tonk (Raj.) India [谷歌学术]) 使用慢速梳理机回收的细毛纤维占毛重的19.6%。回收羊毛的平均纤维直径和髓心分别为 23.2 µm 和 14.0%。回收的羊毛纤维仅使用载体纤维即可纺成 20.7 Nm 的纱线。2.5 旦的尼龙短纤维和细混纺羊毛在半精纺系统上混合纺成纱线。织物在手摇织机上用准备好的纱线织成。即使在去除有毛纤维之后，由于可用的有髓纤维，织物也发现了粗糙的感觉。通过酶处理和柔软剂应用改善了织物的表面性能。评估织物的隔热性和表面光滑度。发现隔热值从 2.03 提高到 2。18 分别用于酶和柔软剂处理的织物。化学处理提高了织物的光滑度/柔软度，即摩擦性能，即。动、静摩擦阻力分别降低 12.4% 和 7.0%。
