Abstract

The invention provides a China hemp native fiber multicomponent blended yarn. The China hemp native fiber multicomponent blended yarn is high in brute force, good in evenness, and anti-pilling, has a soft and smooth yarn body, and is obvious in characteristic and stable in quality. The China hemp native fiber multicomponent blended yarn is blended of 25% of filaments, 15% of China hemp native fibers, 40% of China hemp viscose fibers and 20% of long stapled cotton and made through embedding spinning technique. The invention further provides a preparing method of the China hemp native fiber multicomponent blended yarn. The preparing method comprises the following steps: a, maintenance pretreatment of the China hemp native fibers is conducted, and softening antistatic oiling agents are spayed on the China hemp native fibers; b, blowing and carding of the China hemp native fibers are conducted; c, the processed China hemp native fibers and the long stapled cotton are combed and blended into strips; d, the China hemp viscose fibers are processed into strips independently; and e, the blending combining strips of the China hemp native fibers and the long stapled cotton, and the China hemp viscose fibers are pre-drawn and mixed, then roving and embedding finespinning are conducted, and the filaments are combined during embedding finespinning.

Description

technical field [0001] The invention relates to a blended yarn, in particular to a multi-component blended yarn of hemp primary fiber and a preparation method thereof. Background technique [0002] Hemp is one of the earliest textile fibers used by humans. Hemp has excellent moisture absorption and perspiration properties, natural antibacterial and health care properties, good softness and comfort, excellent UV resistance, excellent high temperature resistance, and unique wave absorption. Adsorption performance and natural rough style, known as the "king of hemp", and widely used in clothing, home textiles, hats, shoe materials, socks, etc. Hemp textiles are especially suitable for sun protection clothing and various work clothes with special needs, as well as sun umbrellas, camping tents, fishing nets, ropes, car seat cushions, lining materials, etc. In addition to being used for clothing, hemp textiles can also be used for interior decoration, which can reduce noise.
