本文阐明了生物棉化改性大麻落麻对其纤维的物理机械性能和化学性能的影响。结果表明用波兰酶制剂Pektopol处理的大麻落麻,工艺纤维束分离变细,因而生产出柔软的棉化大麻纤维,在随后的机械加工中,更易进一步分离成更细的初生纤维束。同时明确了经生物改性与已改性并经梳理后的大麻落麻纤维长度与细度的变化规律。 This paper clarified the biological cotton modified cannabis hemp on the physical and mechanical properties of their fibers and chemical properties. The results showed that the cannabis hemp, treated with the Polish enzyme Pektopol, separated and attenuated the process fiber bundle, thereby producing a soft, henna fiber that was further easily separated into finer nascent fiber bundles in the subsequent machining. At the same time, the rules of the length and the fineness of the modified hemp-modified hemp and cannabis-modified hemp fiber have been clarified.
