The invention relates to a short
fiber spinning method which comprises a cotton blending process, a coiling process, a slivering process, a drawing process, a
combing process, a roving process and a fine
yarn spinning process. The short
fiber spinning method is characterized by further comprising a maintenance process positioned between the roving process and the fine
yarn spinning process, wherein the maintenance process means that rough yarns obtained by the roving process are put in an airtight space, and steam is injected into the airtight space to improve
moisture content of fibers in the rough yarns and
moisture content of capillaries among the fibers. By means of the short
fiber spinning method, the maintenance process is added between the roving process and the fine
yarn spinning process, and the rough yarns are wetted preliminarily before further
processing. In the yarn spinning process, the rough yarns are kept to be wet in the whole process of
processing the rough yarns into fine yarns by means of a spraying device arranged on a fine yarn
machine. Therefore, the
moisture content in different stages of short
fiber spinning is increased,
internal stress among fiber aggregation in different stages of spinning is eliminated, cohesive force among the fibers is increased, and quality indexes of the yarns are increased. The short
fiber spinning method can be widely applied to the short
fiber spinning process.
