Abstract

The invention discloses a production method of high-strength bamboo pulp viscose glue short fiber, which adopts the steps of dipping, squeezing, smashing, maturing, yellowing, spinning, drawing, refining, drying and the like to prepare high-strength bamboo pulp viscose glue short fiber. The high-strength bamboo pulp viscose glue short fiber prepared with the method has dry breaking strength of 3.2-3.4 CN / dtex and wet breaking strength of 2.0-2.3 CN / dtex, is firm and has strong spinnability; fabrics and clothes manufactured by the fiber have favourable toughness and high abrasive resistance; other indexes are all superior to the first-rate product index of FZ / T 52006-2006. The fiber manufactured with the method is ideal material for high-rank clothes and household textiles.

Description

technical field [0001] The invention relates to a production method of viscose fiber, in particular to a production method of high-strength bamboo pulp viscose staple fiber. Background technique [0002] In the textile spinning industry, according to the processing method of bamboo fiber, bamboo fiber can be divided into two types: primary bamboo fiber and regenerated bamboo fiber. Raw bamboo fiber is bamboo fiber made by physical method, and regenerated bamboo fiber is bamboo pulp fiber made by chemical method. [0003] Raw bamboo fiber is made by rolling, twisting and combing bamboo by physical and mechanical methods, and then degumming bamboo fiber, removing sugar, fat, disinfecting and drying. Bamboo fiber has the advantages of coolness, moisture absorption, breathability, and perspiration, and has natural antibacterial properties, which has attracted the attention of the international market. However, due to its natural nature and long processing steps, the fineness a...
