A method for manufacturing a burnable-coal burner having a dry feeling of coolness

摘要

The present invention relates to a method for producing a composite false twist yarn having a dry feeling of coolness composed of two types of polyester filaments having a difference in elongation of at least 50% Shaped cross-section yarns radiated by a spinning-discharging hole having a cross-section of elliptical, elliptic, cross and circular shapes as shown in Fig. 1, alone or in combination, and a single yarn fineness having a single yarn fineness of 0.8 to 2 denier Is formed so as to be surrounded by the S-shape and the Z-shape, so that a part of the polygonal cross-section of the core part is expressed, and the skin contact area is relatively smaller than that of the composite-Can be obtained.
