Long / short composite spun yarn, method for producing the same, and textile products including knitted or knitted fabrics including long / short composite spun yarn

摘要

The multi-filament yarn and the short fiber bundle 20 are long and short composite spun yarns 20. The multi-filament yarn 22 is twisted together with the short fiber bundle in a substantially untwisted state, whereby the number of twists of the multi-filament yarn is increased. Is substantially the same as the long and short composite spun yarn 20, and the constituent fibers 22 of the non-twisted multifilament yarn and the constituent fibers 21 of the short fiber bundle are continuously dispersed in the length direction. The multifilament yarn is preferably at least one selected from false twisted crimp yarns, indented crimped yarns, gear crimped yarns, knitted denit crimped yarns, and latent crimped yarns including composite fibers.
