Rotor Cotton Yarns with the Content of Enzymatically Modified Hemp Fibers

摘要

The paper reports on a method of preparing hemp fibers for rotor spinning in blends with cotton. Uzbekistan cotton and hemp noils with the linear mass of 5.6 tex and length from 162 mm were used in the experiments. The hemp noils were cottonized in an enzymatic process yielding cottonized hemp fibers with the linear mass of 3.34 tex and 37.4 mm long. Yarn production experiments were made on a BD 200RN rotor machine by using a cotton-hemp sliver with the linear mass of 4.5 ktex. The content of cottonized hemp fibers in the blend with cotton was 30%, 40%, and 50%. Cotton-hemp-blended yarns were produced with linear mass of 32, 40, and 50 tex for the 70/30 blend, 50 tex for the 60/40 blend, and 100 tex for the 50/50 blend. Spinability tests showed that 50% is the limit for the content of hemp fibers in blends with cotton.%本文报道一种制备大麻纤维用于棉混纺转杯纺纱方法。在实验中使用乌兹别克斯 坦棉花和大麻绒其线性量为5.6 tex和长度从162毫米。用3.34特克斯和37.4毫 米长的线和用酶法工艺棉纱化麻纤维对麻绒棉化。使用棉，麻棉条的线质量 4.5ktex -个BD200RN的转子机，纱产量进行了试验。棉大麻纤维与棉花在共混 物中的含量是30,40和50%。棉麻混纺纱生产与线性质量为70/30的共混 物，50 tex的为60/40的共混物和100 tex的为50/50的共混物中的32.40和50 特。可纺性试验表明，其麻棉混纺对麻含量限制为50%。
