Preparation method of bulk acrylic fiber and cashmere blended fiber

The invention discloses a preparation method of bulk acrylic fiber and cashmere blended fiber, and relates to the technical field of textile. The preparation method comprises the following steps of wool blending and opening, bin closing, wool carding, ring spinning, spooling, doubling, double twisting, flower twisting, yarn steaming and rewinding. Compared with the prior art, clothes woven by the blended yarn generally do not need to pass through a fulling machine, can be fulled only by being washed with hot water, and can be kept stable for a long time subsequently. The weaving cost of the fabric is greatly reduced under the condition of ensuring the quality. 本发明公开了一种膨体腈纶羊绒混纺纤维制备方法，涉及纺织技术领域，包括以下几个步骤：和毛开松-闷仓-梳毛-环锭细纱-络筒-并线-倍捻-花捻-蒸纱-倒筒。与现有技术相比，通过本混纺纱线织造的衣物通常无需再经过缩呢机，只需要热水洗就可缩呢，随后可保持长久稳定。在保证质量的情况下极大的降低了织物的织造成本。
