Abstract

The invention discloses a heating blended yarn and a spinning process thereof. The heating blended yarn comprises the following components in percentage by weight: 5% to 15% of heating fiber, 25% to 30% of anti-pilling acrylic fiber, 20% to 25% of modal fiber, 20% to 25% of tencel fiber and 20% to 25% of viscose fiber. The fibers are spun to yarn through a semi-comb spinning process. The spinningprocess sequentially comprises a dyeing process, a cotton carding process, a drawing process, a roving process, a spinning process and a spooling process. The heating blended yarn is formed by blending various types of fibers, highlights the characteristics of each fiber by reasonably arranging the weight ratio of each fiber, integrates the advantages of various types of the fibers into a whole, maintains the basic performance of the yarn, and has the heating and warming functions. The yarn is more fluffy and softer than spun yarn and is more uniform and glossy than the coarse yarn. The adaptability of the semi-comb spinning process route to raw materials is wider, the spinning quantity can be high or low, the technology is popularized, equipment investment is low, and occupied plant areais small.

Description

technical field [0001] The invention relates to the textile industry, in particular to a heat-generating blended yarn and a spinning process thereof. Background technique [0002] With the development of the social economy and the improvement of people's living standards, people's consumption concepts are constantly updated, and they pay more and more attention to the quality of life and the living environment, and the functional requirements for clothing are also getting higher and higher, especially for clothing. , health care, feel, quality and other aspects of the requirements are also constantly improving. The yarn made of heat-generating fibers blended with other fibers, the moisture-absorbing and heat-generating EKS fibers produced by Toyobo Co., Ltd. in Japan, have better heat-retaining performance than other heat-insulating materials (phase-change thermal fibers and solar thermal fibers), and have broader application prospects. . The production method of the fiber...
