The invention discloses a method for preparing functional highly-twisted color dot
yarn. The color dot
yarn prepared by means of the method is formed through the steps that color fibers are intermittently implanted in the process of twisting filaments, discontinuous color dots are formed on the surfaces of the filaments, and the thickness and length of the color dots can be controlled. The color dot
yarn has more changes in the color of the yarn, the three-dimensional feeling of the yarn is stronger, more changes are provided for the style of fabric, the variety of the filaments is enriched, and the progress and development of a filament technology are promoted. In the prepared color dot yarn,
copper ammonia fiber filaments and ultra-high molecular weight
polyethylene fiber filaments adopted as the filaments, and after being highly twisted, the filaments have the performance of cooling, air permeability,
moisture absorption, high strength,
wear resistance and the like; in the twistingprocess, luminous
fiber color dots with two colors are added, the luminous fibers can emit light in the
daytime and at night, different colors are presented, and the color richness and three-dimensional feeling of the highly-twisted yarn are improved; by means of the method, the application of the functional fibers is promoted, and the design of
textile products is enriched.
