精纺羊驼毛纱生产工艺的研究

Research on the production process for worsted alpaca yarn

介绍了羊驼毛的品质特性及产品特点,针对羊驼毛刚性大,纤维抱合力小,可纺性差,纺纱断头高、落毛多、生产效率低、成纱质量差等问题,从原料选择、纺纱工艺流程、工艺技术改进和工序质量控制等方面进行工艺研究。通过试生产不断调整上机工艺参数,解决了羊驼毛纺纱的关键工艺技术难题,在此基础上制定出批量生产上机工艺和质量控制要求,保证了大批量生产羊驼毛纱生产效率和成纱质量的稳定,为羊驼毛大衣呢产品的生产打下了良好的基础。

In the paper, the characteristics of alpaca fiber and the features of its product are introduced. According to the shortages of alpaca fiber, such as rigidity, small cohesive force for spinning, more wasters, low productivity and poor quality, the research focus on materials selection, spinning technical processes and quality control. The research indicates that the key problems above could solved by using a suit technical processes and proper parameters. Based on the results, large quantity and good quality of worsted alpaca yarn are produced. And the products are successfully used for making alpaca overcoats.
