经纱的超声波辅助上浆技术研究

Ultrasonic assisted warp sizing technology

针对常规经纱上浆工艺存在高能耗和上浆效果不均匀等问题,应用超声波技术辅助经纱上浆,考察了超声波功率、浆料浓度、上浆时间和上浆温度对经纱上浆率的影响。结果表明:超声波可以显著提高经纱的上浆率,在超声波功率为600 W、上浆时间为10 min、上浆温度为60℃、浆料对水的体积分数为10%时,上浆率可达12.15%。超声波作用下经纱上浆后断裂强度、断裂伸长率和耐磨次数有所提高。

To solve the problem of high energy consumption and uneven sizing in the traditional sizing process, an integrated ultrasonic sizing technology was developed. The effects of ultrasonic power, slurry concentration, sizing time and sizing temperature on the warp sizing rate were investigated. The results indicated that ultrasonic could significantly increase the sizing rate of warp yarns. When the ultrasonic power was 600 W, the sizing time was 10 min, the sizing temperature was 60 ℃, the volume ratio of slurry to water was10%, the sizing efficiency was 12.15%. Under the effect of ultrasonic sizing, the breaking strength, elongation at breaking and wearing times of the warp improved somewhat.
