Abstract

The invention provides moisture-absorbing and heating yarn and a preparation and dyeing method thereof. The moisture-absorbing and heating yarn is characterized by consisting of modified coffee-carbon polyester staple fiber with the mass fraction of 20-40% and viscose staple fiber with the mass fraction of 60-80%, wherein the total amount of the modified coffee-carbon polyester staple fiber and the viscose short fiber is 100wt%. The moisture-absorbing and heating yarn and the preparation and dyeing method thereof provided by the invention have the advantages that because of the introduction of hydrophilic groups, the fiber moisture absorption rate can be increased; simultaneously, when dyeing with viscose, one-bath piece dyeing with active dye can be realized, so that the dyeing procedure is greatly reduced, the dyeing cost is reduced and the dyeing uniformity is improved. The moisture-absorbing and heating yarn can be widely applied to the field of clothing and is especially used for preparing textiles such as household underwear.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a moisture-absorbing and heating yarn and a preparation and dyeing method thereof. Background technique [0002] With the improvement of people's living standards, the functions of clothing are also developing towards diversification, not only being limited to simple covering and keeping warm. At the same time, people have higher and higher requirements for the comfort and environmental protection of clothing. This requires more processing space for clothing raw materials and can adapt to different needs. In order to wear comfortably and beautifully in winter, fabrics that absorb moisture and generate heat have emerged as the times require. And the key point of moisture absorption heating fabric is the preparation of moisture absorption heating yarn. The principle of moisture absorption and heat generation is: (1) The highly hydrophilic polar groups on the fiber molecules in ...
