Abstract

The invention provides a bamboo charcoal viscose flat yarn and a production process thereof, in order to meet the requirements of clients on product markets. The bamboo charcoal viscose flat yarn is characterized by being prepared through the following steps: mixing the bamboo charcoal pulp with viscose through injection before spinning and performing wet spinning and post-treatment, wherein the flatness of the yarn is (10-500):1, the content of the bamboo charcoal is 0.1-10 percent of the total weight of the fiber, the ammonia absorption rate is greater than or equal to 50 percent, the permeability is greater than or equal to 500mm/s, and the color fastness to washing is class 4-5. The bamboo charcoal viscose flat yarn is a new product, which has antibacterial, anti-ultraviolet and deodorization functions, also has good permeability and wet absorption and is a degradable environment-friendly fiber.

Description

technical field [0001] The invention relates to the technical field of viscose in the textile industry, in particular to a bamboo charcoal viscose flat yarn and a production process thereof. Background technique [0002] Flat yarn is a new type of Vicat fiber with a flat cross-section that is spun by a special process. It combines the excellent properties of ordinary Vicat fiber and hemp fiber. The fabric is smooth, elastic and soft, rich in three-dimensionality, comfortable and pleasant; it has the characteristics of moisture absorption and heat dissipation, and is easier to dye. [0003] Flat viscose monofilament is untwisted or low-twisted flat single viscose filament. The thread has a certain flatness and soft hand feeling. It is available in the range of denier 300~6000D. Flat viscose monofilament is natural cellulose fiber The raw material production is a degradable and environmentally friendly fiber, which is widely used in various fields such as gift wrapping belts,...
