Description

Four-component functional yarn and preparation method thereof Technical Field The invention relates to the technical field of textile, in particular to a four-component functional yarn and a preparation method thereof. Background Along with the upgrading of the demands of consumers on the functionality and comfort of textiles, the multi-component functional yarn becomes an industry development trend, but the problems of the synergistic compatibility of multi-component raw materials and the spinnability of special functional raw materials become key bottlenecks for restricting the development of the functional yarn. The Xinjiang long staple cotton fiber has long length and high strength, can endow yarn with good softness and air permeability, but lacks functions of deodorization, moisture absorption, quick drying and the like when being singly used, has more longitudinal grooves of high-profile-section polyester staple fibers, has excellent moisture absorption, quick drying and high rigidity, needs to be optimized and improved by a process for compatibility with natural fibers, and can improve the elasticity, warmth retention and pilling resistance of the yarn when being used for warmth retention, but the poor proportion control can influence the overall softness of the yarn. In the prior art, the raw material proportion of the multicomponent yarn depends on empirical values, a comparison verification system of a system is not formed, so that the functionality and spinnability are difficult to balance, a conventional cotton spinning scheme is used for the spinning process of the deodorant cotton, special optimization measures are not designed for the characteristics of the deodorant cotton, the fiber clusters are difficult to "tear loose" in an opening stage, the fibers are frequently wound around cylinder needle teeth in a carding stage, the fibers are adhered or electrostatically charged due to improper temperature and humidity control in a sliver forming stage, hard spots are formed due to uneven dispersion of the deodorant in a spinning stage, broken ends are finally caused, and the functionality of the finished yarn is unstable, and the qualification rate is low. Disclosure of Invention The invention aims to solve the defects and provide a four-component functional yarn and a preparation method thereof, and the four-component functional yarn is prepared by designing a full-flow optimization scheme from raw material pretreatment to a forming process and combining multicomponent raw material proportioning screening to realize the collaborative promotion of the spinnability of the deodorizing cotton and the yarn functionality through definitely solving the problems and causes of the deodorizing cotton spinning. In order to solve the technical problems, the invention adopts the following technical scheme that the four-component functional yarn comprises 17-27% of deodorant cotton, 30-33% of Xinjiang long staple cotton, 30-38% of polyester staple fiber with special-shaped cross section and 10-15% of warm-keeping acrylic fiber according to mass percentage.
