Problems solved by technology

Therefore, the fabric is easily deformed by rubbing force during washing, and it is easy to shrink after drying, and its size is unstable.
Therefore, the blended fabric of bamboo cellulose fiber and cotton prepared by this process is relatively poor in the mercerizing treatment ability to improve the appearance of the fabric
Another disadvantage is that the fabric must be dyed in a loose type, because the wet modulus is not high. If the dyeing process is carried out under tension, the fabric will shrink violently during use. Therefore, it is inconvenient for the dyeing process to be carried out continuously.

Abstract

The invention discloses a production method of high wet modulus bamboo pulp viscose glue fiber, which adopts the steps of dipping, squeezing, smashing, maturing, sulfonating, spinning, drawing, refining, drying and the like to prepare high wet modulus bamboo pulp viscose glue fiber. The high wet modulus bamboo pulp viscose glue fiber prepared with the method of the invention has dry breaking strength of 3.2-3.8 CN / dtex, wet breaking strength of 2.0-2.4 CN / dtex and wet modulus of 0.60-0.65 CN / dtex, has the characteristics of high humidity modulus, better purity, favourable affinity for dyestuff, non-fibrillation, non-fibrillar structure and the like, reduces expansion, reduces water retention capacity and improves alkali stability. Prepared fabric has silky luster and draping property, is extremely soft, has excellent dyeability and vivid luster and can keep bright and colorful after being cleaned several times.

Description

technical field [0001] The invention relates to a production method of viscose fiber, in particular to a production method of high wet modulus bamboo pulp viscose 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 and o...
