The invention discloses a multifunctional air vortex
spinning yarn which comprises a core
yarn, a middle
yarn and a covering yarn, wherein the core yarn is formed by twisting and combination of firstyarn bundles, second yarn bundles and third yarn bundles; the first yarn bundles are carbon
fiber filaments; the second yarn bundles are
nylon fiber filaments; the third yarn bundles are
polyester fiber filaments; the middle yarn is
aramid fiber short fiber; the core yarn is located in the middle yarn; the covering yarn is a
fire retardant fiber layer; and the covering yarn is spirally wound and wrapped outside the middle yarn. The multifunctional air vortex
spinning yarn is reasonable in structure, the core yarn and the middle yarn enter from a vortex
spinning core tube, the covering yarn enters from a vortex spinning outer tube, and the produced multifunctional air vortex spinning yarn is less in hairs and does not
pill; because the middle yarn in
aramid fiber short fiber, the core yarnis uniform in stress, good in structure strength, and uneasy to fracture, and can be used as high-strength yarn; the covering yarn adopts combination of
flame-retardant
acrylic fiber and tencel fiber,has good
flame retardant performance, and is smooth in surface, comfortable in wearing good in
wear resistant property, and easy to wash, can dry fast, and has a cold feeling.
