The invention discloses a tencel blended
yarn. The tencel blended
yarn consists of tencel fibers and
far infrared fibers in a blended manner, wherein the weight content of the tencel fibers accounts for 60-65 percent of the tencel blended
yarn, and the weight content of the
far infrared fibers accounts for 35-40 percent of the tencel blended yarn. A preparation method for the
far infrared fibers comprises the steps that far
infrared ultrafine micro
powder and
fiber basic material are mixed and dried, a
polymer spinning aid agent is added to the mixture, the mixture is fed to a screw-type extruder and is subjected to
melt blending extrusion and
granulation, and then far
infrared master batch is obtained; the far
infrared master batch and
fiber chips are blended, spun, wound and stretched to form the far infrared fibers; the far infrared ultrafine micro
powder consists of the following compositions in parts by weight: 60-75 parts of seaweed carbon
fiber, 15-20 parts of aluminum
oxide, 5-15 parts of zirconia, 5-10 parts of
tourmaline and 2-5 parts of glass beads. The tencel blended yarn provided by the invention combines the health and environmental-protection characters of the tencel fibers with the warm-keeping effect of the far infrared fibers, has the advantages of
natural property,
environmental protection and warm keeping and the like, and is applicable to garment fabric and other industries.
