香蕉纤维纱性能研究及针织物可编织性分析

Study of Banana Fiber Yarn Properties and Its Knitting Feasibility Analysis

选用香蕉纤维、棉混纺纱(55∶45),纯香蕉纤维纱,苎麻、棉混纺纱(55∶45),亚麻、棉混纺纱(55∶45),以及纯棉纱,测试对比分析它们的拉伸断裂强度、捻度、回潮率、百米质量变异系数、毛羽等物理性能,并在横机上进行编织试验,研究它们用于针织物编织的可行性。结果表明:香蕉、棉混纺纱强力和条干均匀度均好于香蕉纤维纯纺纱,且手感柔软,其编织性能好于香蕉纤维纯纺纱,符合针织布生产要求;香蕉纤维纯纺纱刚度较大,手感硬挺,毛羽多,编织比较困难,编织之前应考虑进行柔软处理,并需适当给湿,以减少飞花、断纱。本研究为香蕉纤维针织物新产品开发提供理论依据和技术支持。

The paper tests and analyzes the tensile breaking strength, twist, moisture regain, CV value, yarn hairiness of 5 kinds yams, including banana fiber/cotton blended yam （55：45）, pure banana fiber yam, ramie fiber/cotton blended yam（55：45）, flax fiber/cotton blended yarn（55：45） and pure cotton yam, and also discusses the knitting feasibility of these yams on fiat knitting machine. The results show that the strength and evenness of bananafiber/cotton blended yarn are better than those of pure banana fiber yarn, as well as the soft hand, which can be used for developing knitted fabrics; while the pure banana fiber yarn has large rigidity, hard hand and more yarnhairiness, so it is necessary to make some softening finishing and wetting process before knitting to reduce the fiber fly and broken yarn. The achievements made in this paper can provide some theoretical basis and technical support for developing banana fiber knitted product.
