Abstract: The method features that the apparatuses for rotor spinning and double-twisting are used. After twist coefficient of rotor spinning is reduced, it is increased then on double-twisting frame, so making the yarn have high output, low cost and high strength. The yarn is suitable for denim or drill.
本发明利用转杯纺和倍捻纺的设备及降低转杯纺的捻系数后在倍捻纺上再增加部分捻系数,可在保留转杯纺高产、成本低优点的基础上,提高成纱强力、改善表层加捻纹路,适用于要求成纱强力高,加捻纹路明显的牛仔布、斜纹布等产品。
