One kind apocynum, polyvinyl alcohol and long-staple cotton spinning production process

The invention relates to the field of ramie/cotton product production, in particular to a dogbane, vinylon and long stapled cotton spinning production process, which is characterized by comprising the following steps of: performing preprocessing, pre-spinning preparation and humidification preservation on dogbane, vinylon and long stapled cotton; blending the dogbane, vinylon and long stapled cotton; feeding into a blending willow, a cotton cleaner, a carding machine, a three-pass drawing machine, a roving frame, a spinning frame and a bobbin winder in turn; and finally obtaining the finishedspun yarns.
