| I.P Abstract & Summary |
A method of producing a hemp-blended single spun yarn may include: a fiber blending step of passing hemp fiber, together with latent and potential crimped yarn fiber, through an opener in order to increase the cohesion of the hemp fiber by the three-dimensional chain structure, thereby producing a blended fiber including 10% to 60% latent and potential crimped yarn fiber; a sliver production step of carding the blended fiber through a carding machine, and drafting the carded fiber through a drafting machine, thereby producing a sliver; and a spinning step of supplying the sliver as a roving yarn through a plurality of rollers to a twisting unit, and supplying a combined filament yarn, produced by combined twisting and having a structure in which a low-stretchability filament yarn surrounds a high-stretchability filament yarn, as a core yarn to the twisting unit without being passed through the plurality of rollers. |
