Novel blended yarn and production method and application thereof

The invention relates to a novel blended yarn and a production method and application thereof. The novel blended yarn is formed by blending fine-denier modal fibers and long stapled cotton fibers according to the weight ratio of (52-55):(45-48). According to the production method, the novel blended yarn is manufactured in the mode that the fine-denier modal fibers and the long stapled cotton fibers are used as raw materials and are sequentially subjected to a health preserving procedure, a blowing procedure, a cotton carding procedure, a drawing procedure, a roving procedure, a spinning procedure and a spooling procedure, wherein in the spinning process, the spinning twist is 150 twists/10 cm-160 twists/10 cm, the spinning temperature is 30+/-3 DEG C, and the spinning humidity is 48%-55%.The invention further provides the application of the novel blended yarn in manufacturing of a high-grade garment fabric. The obtained medium-high count yarn is thin and high in strength, and the count of the medium-high coun
