半紧密纺在毛半精纺产品生产中的应用

Application of semi-compact spinning in producing semi-worsted product

介绍了半紧密纺技术在毛半精纺产品生产中的应用实例，分析了半紧密纺加捻机理及其成纱结构与传统环锭纺和气动紧密纺的不同，详述了半紧密纺技术装置的构成。经生产实践证明，半紧密纺毛半精纺纱线的条干均匀度、细节、粗节、毛粒等指标均有明显的改善，其织物抗起毛起球等级提高了0．5～1级。织物保持了毛纺产品原有的特性，并且手感更柔软，表面更光洁。该技术在半精梳毛纺设备上改造成本低廉，生产中可节能，无污染，将有可能成为未来纺织业发展的一个方向。

Application of semi -compact spinning in producing semi -worsted product is introduced with its twisting mechanism, yarn forming structure and its differences against traditional ring spinning and pneumatic compact spinning analyzed by practical production. The technical structure of this semi - worsted yarn spun by semi - compact spinning shows that the indexes of yarn eveness and yarn thin and thick places are all obviously improved. The anti - pilling of its fabric is raised 0. 5 - 1 grade with fabric handle more soft and fabric surface more smooth. The technology is of low cost, energy saving and no pollution that will be a developing trend of future textile industry.
