Siro-spinning core-spun yarn blended with soybean fiber and bamboo fiber and spinning technology

The invention discloses a Siro-spinning core-spun yarn blended with soybean fiber and bamboo fiber and spinning technology. The blended yarn is produced by blending soybean fiber and bamboo fiber, wherein, the content of the soybean fiber is 1%-9%, and the residual is bamboo fiber. Siro-spinning is adopted; and spandex filament is added to produce Siro-spinning core-spun yarn. The blended yarn has the advantages of the soybean fiber and the bamboo fiber, at the same time, the spandex filament is added, so that the blended yarn has a good elasticity, a good shape-retaining ability, and has no wrinkling. 本发明公开了大豆纤维与竹纤维混纺赛络包芯纱线及其纺纱工艺。所述混纺纱线由大豆纤维与竹纤维通过混纺工艺混纺而成，其中大豆纤维的含量为1％～99％，余量为竹纤维，细纱工序采用赛络纺纱，加入氨纶长丝，纺制出赛络氨纶包芯纱线。该混纺纱线既具有大豆纤维的优点、又具有竹纤维的特点，同时附加氨纶长丝，弹性好，不起皱、保型性好。
