The invention discloses a blended yarn product of copper modified polyester fibers and bamboo fibers and a spinning method of the blended yarn product. The blended yarn product comprises 38%-43% of the copper modified polyester fibers and the balance bamboo fibers. Premixing is conducted on the copper modified polyester fibers and the bamboo fibers, and the blended yarn product is obtained through a sliver blending method in a multi-step blending mode. According to the indexes of the spun yarn, the CVm is 12.60%, H is 3.0, snicks below 50 account for 5%, slugs above 50 account for 15%, neps above 200 account for 18%, the strength is 260 CN, and the nip gauge is 2.25 mm. According to the blended yarn product of the copper modified polyester fibers and the bamboo fibers and the spinning method of the blended yarn product, 38%-43% of the copper modified polyester fibers and the bamboo fibers are blended to obtain the blended yarn product, the advantages that the bamboo fibers are smooth, overhanging and naturally antimicrobial and have the excellent moisture absorption and desorption property stand out, and the defects that the bamboo fibers are low in strength and poor in abrasive resistance are overcome; fabric of the blended yarn product has the advantages of being smooth, stiff, unrestrained, good in conformality, hygroscopic, breathable, resistant to ultraviolet rays, antibacterial and bacteriostatic, deodorant, healthy, sanitarian and the like; noble and elegant demeanor is absolutely shown.
