The present invention provides a thermally bondable core-sheath type composite fiber mixture including 50 to 80 wt% of first core-sheath type composite fibers with eccentricity of 20% or less and 20-50 wt% of second core-sheath type composite fibers with eccentricity of 60% or greater. When non-woven fabric is manufactured using the thermally bondable core-sheath type composite fiber mixture according to the present invention, workability parameters including carding performance, width reduction, the generation of dust and nep, and the likes are improved and shape stability can be maintained. Moreover, a non-woven fabric manufactured using the thermally bondable core-sheath type composite fiber mixture according to the present invention has improved uniformity ratio of illuminance, bulkiness, and softness. |
