Woolen fiber and cotton fiber blended coated polyester filament yarn and spinning process thereof

The invention discloses woolen fiber and cotton fiber blended coated polyester filament yarn and a spinning process thereof. The content of the woolen fiber in the yarn is 5-82%, the polyester contentis 17-19%, and the balance is cotton fiber. A blending mode of woolen fiber two-premixing and mixing is adopted, which is favorable for accurate blending ratio and uniform composition. The blended yarn produced through the production process has high single yarn strength, uniform evenness, fewer neps, and fewer yarn defects. The yarn structure can further improve the comfort of a fabric, improvethe fabric touch, and improve the fabric grade. The yarn not only has the advantages of the woolen fiber, but also has the advantages of the cotton fiber, is high in strength, low in cost, resistant to bacteria and odor and good in touch, and is an excellent choice for the production of infant clothing, home textile products, medical care products and high-grade clothing fabrics. . 本发明公开了种羊毛纤维与棉纤维混纺包覆涤纶长丝纱线及其纺纱工艺。纱线中羊毛纤维的含
