Abstract

The invention discloses a single-fiber fine-denier viscose filament yarn and a production method thereof. The production method comprises the following steps: soaking mixed pulp of cotton, wood and bamboo in a 210-250g / L NaOH solution at a temperature of 38-55 DEG C, and performing oxidative degradation on alkali cellulose at a temperature of 25-50 DEG C; performing yellowing reaction on the alkali cellulose and CS2 with the addition amount accounting for 32.5-35% of the amount of alpha-cell to obtain cellulose xanthate, then, adding dissolved alkali liquor and soft water to dissolve the cellulose xanthate into dissolved gum; grinding the dissolved gum at a temperature of 12-20 DEG C, dissolving, homogenizing, mixing, filtering and ripening to obtain spinning viscose; coagulating the spinning viscose in a coagulating bath, dissolving and regenerating to prepare the fine-denier viscose filament yarn with the fineness of 0.5dtex-1.11dtex. The single-fiber fine-denier viscose filament yarn produced by adopting the preparation method is compact in structure, soft in hand feeling, fine in texture, soft, full, high in elasticity, good in conformality, strong in cleaning capacity, high in moisture absorption, gas permeability, antibacterial, bacteriostatic, and excellent in wearability.

Description

technical field [0001] The invention relates to a viscose filament and a production method thereof, in particular to a production method of a single fine denier viscose filament. Background technique [0002] The property of viscose filament is regenerated cellulose fiber. The fabric made of it is soft, smooth, moisture-absorbing and breathable, the fabric is drapeable, easy to dye, antistatic, and has excellent wearability. It is an important yarn in the textile field. One of the raw materials. At present, viscose filament has formed a serialized product scale with a multifilament fineness of 33.3dtex~666.7dtex and a single filament fineness of 2.22dtex~66.7dtex. In recent years, with the changes in market demand for high-end textiles and the development and application of high-tech in the textile industry, the development and application of high-performance, functional, and differentiated textile raw materials have been promoted. Fine denier viscose filaments and producti...
