Abstract

The invention discloses a short fiber composite spinning device which comprises a first drawing mechanism, a second drawing mechanism and a third drawing mechanism. A feeding port of the first drawing mechanism is provided with a first roller; a second roller is pressed on the first roller; the first drawing mechanism is internally provided with a first sleeve through a bearing; the inner side of the first sleeve is provided with a second thread layer; the second drawing mechanism comprises a second sleeve; the two sides of the second sleeve are respectively provided with a feeding tube; each feeding tube is provided with a second spray head; the second sleeve is internally and uniformly provided with a plurality of first spray holes; the third drawing mechanism comprises an arc-shaped conduit; the arc-shaped conduit is internally provided with a plurality of second spray holes; the exit place of the arc-shaped conduit is provided with a compaction roller; and the exit place of the compaction roller is provided with a coiler disc. The invention also discloses a spinning method for the short fiber composite spinning device. The short fiber composite spinning device and the spinning method thereof can solve the defects in the prior art, and can improve softness of short fiber spun yarns.

Description

technical field [0001] The invention relates to the technical field of short fiber spinning, in particular to a short fiber composite spinning device and a spinning method thereof. Background technique [0002] In the spinning process, there are corresponding requirements for raw materials. Among them, the fiber length has different requirements according to the characteristics of different equipment. Generally speaking, for fibers with shorter length, the processing difficulty and utilization rate are lower, which affects the application of short fibers in spinning. Chinese invention patent CN 102312305 B discloses a three-axis composite spinning device and spinning method for short fibers that are prone to chipping, and provides a solution for triaxial composite spinning. However, the softness of the yarn produced by this solution is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a short fiber composi...
