摘要： 为开发出品质优良的涤纶/染色棉/PHBV基涤纶(混合比为50∶35∶15,PHBV为聚(3-羟基丁酸酯-co-3-羟基戊酸酯)喷气涡流纺混纺纱线,基于Box-Behnken设计和响应曲面模型分析,研究喷气涡流纺主要成纱工艺纺纱速度、喷嘴气压和1/纱线线密度对混纺纱断裂强度、断裂伸长率、断裂功、条干CV值和毛羽H值的影响规律。结果表明:混纺纱的强伸性能和毛羽H值均受到纺纱速度、喷嘴气压和1/纱线线密度的影响,纱线条干CV值受1/纱线线密度的影响显著。随着纺纱速度的提升,纱线断裂强度、毛羽H值呈增大趋势,断裂伸长率逐渐减小,断裂功几乎不发生变化。随着喷嘴气压的增加,纱线断裂强度和断裂功总体呈先增大后减小的趋势,断裂伸长率总体呈增大趋势,毛羽H值呈减小趋势。随着1/纱线线密度的增大(纱线变细),纱线的断裂强度、断裂伸长率、断裂功、毛羽H值均逐渐减小,纱线条干均匀性逐渐变差。

Abstract:

Objective This study investigates the influences of key spinning parameters on the performance of polyester fiber/dyed cotton fiber/ PHBV-based polyester fiber (50/35/15) air-jet vortex spinning blended yarn.By optimizing spinning conditions, the research aims to enhance yarn quality, thus providing scientific guidance for industrial parameter settings and improving the efficiency and sustainability of blended yarn manufacturing.

Method Based on Box-Behnken Design (BBD) and response surface model analysis, the influences of delivery speed, nozzle pressure and the reciprocal of yarn linear density on the break strength, elongation at break, breaking work, evenness CV value and hairiness H value of blended yarn were studied.

Results Statistical analysis of the test results indicated that the delivery speeds, nozzle pressure and the reciprocal of yarn linear density had significant effect on the yarn tenacity, elongation at break, breaking work and hairiness H value, and the reciprocal of yarn linear density has a significant effect on the yarn evenness CV value. Through the change of yarn break strength, it was found that the yarn break strength exhibited an increase and then followed by a decrease with the increase of nozzle pressure, and demonstrated a decreasing trend with the increase of the reciprocal of yarn linear density. The yarn break strength increased slowly with the change of the delivery speed, and this change became obvious when the reciprocal of yarn linear density was on small values (i.e. with thicker yarns). The elongation at break of the yarn decreases with higher reciprocal of yarn linear density and delivery speeds, primarily due to reduced fiber slippage in the yarn. The elongation at break of the yarn increased slowly with the increase of the nozzle pressure. The yarn breaking work was related to the change of yarn tenacity and break elongation, and it was most affected by the reciprocal of yarn linear density in such a way that yarn breaking work would increase with the decrease of the reciprocal of yarn linear density. The yarn evenness CV value demonstrated increase with the increase of the reciprocal of yarn linear density. It was found that that the yarn hairiness H value decreased with the increase of the reciprocal of yarn linear density and nozzle air pressure, and decreased with the decrease of delivery speed.

Conclusion In the spinning process, increasing the delivery speed properly can reduce the fiber loss in the twisting chamber enhancing the fiber wrapping effect, which is beneficial to the yarn break strength. Increasing the delivery speed would reduce the probability of fiber slippage within the yarn, leading to reduced elongation at break of the yarn. The change of delivery speed has little effect on yarn breaking work, because the trend of yarn and breaking elongation is opposite. The result showed that the yarn was prone to hair formation with the increase of delivery speed. For polyester fiber/dyed cotton fiber/PHBV-based polyester fiber (the blend ratio of 50∶35∶15) air-jet spinning blended yarn, when the nozzle pressure is set near 0.55 MPa, the yarn can obtain satisfactory breaking work. With the increase of the nozzle pressure, the twisting degree of the wrapped fiber increases and the yarn hairiness decreases. The yarn evenness CV value is mainly affected by the yarn linear density. When the yarn is finer, it is easy to form draft fluctuations, resulting in yarn evenness variation.
