Embodiment 1

[0008] Embodiment one: a kind of method for making viscose fiber knitted fabric, it is characterized in that, it comprises the following steps: select bamboo fiber and the wood fiber that the wood of sustainable development forest area extracts, and the weight ratio of wood fiber and bamboo fiber is 8:1 , put them into the digester for cooking and pulping respectively, add hydrogen peroxide accounting for 2.5% of the absolute dry mass of the cellulose raw material, sodium hydroxide accounting for 10% of the absolute dry mass of the cellulose raw material, and Bio-enzyme (such as glucose oxidase) with a mass fraction of 2% of the absolute dry mass of the cellulose raw material, the cooking temperature is 110°C, and the heat preservation is 98min; Put into the dipping bucket that lye is housed, squeeze by press, add carbon disulfide to carry out yellowing by yellowing machine, carbon disulfide addition is 45% of the quality of the alkali cellulose obtained by pressing, and yellow...

Embodiment 2

[0009] Embodiment two: a kind of method for making viscose fiber knitted fabric, it is characterized in that, it comprises the following steps: select bamboo fiber and the wood fiber that the wood of sustainable development forest area extracts, and the weight ratio of wood fiber and bamboo fiber is 9:1 , respectively put into the digester for cooking and pulping, adding hydrogen peroxide accounting for 2% mass fraction of the absolute dry mass of the cellulose raw material, sodium hydroxide accounting for 5% of the absolute dry mass of the cellulose raw material, and accounting for The absolute dry mass of the cellulose raw material is biological enzyme with a mass fraction of 1%, the cooking temperature is 120°C, and the temperature is kept for 100min; then it is washed, beaten by a beater, mixed with dissolving wood pulp and dissolving bamboo pulp, and placed in a tank with lye. Immerse in the dipping barrel, press through a press, and add carbon disulfide through a yellowin...

Embodiment 3

[0010] Embodiment three: a kind of method for making viscose fiber knitted fabric, it is characterized in that, it comprises the following steps: choose the wood fiber that the wood extracting of bamboo fiber and sustainable development forest area, wood fiber and bamboo fiber weight ratio are 8.5:1 , were respectively placed in the digester for cooking and pulping. During the cooking process, hydrogen peroxide accounting for 3% of the absolute dry mass of the cellulose raw material, sodium hydroxide accounting for 8% of the absolute dry mass of the cellulose raw material, and The absolute dry mass of the cellulose raw material is biological enzyme with a mass fraction of 3%, the cooking temperature is 130°C, and the temperature is kept for 110min; then it is washed, beaten by a beater, mixed with dissolving wood pulp and dissolving bamboo pulp, and placed in a tank with lye. Immerse in the dipping barrel, press through a press, and add carbon disulfide through a yellowing mach...

Abstract

The invention provides a viscose knitted fabric manufacturing method, the manufacturing process is more environmentally friendly, and manufactured fabric is good in bulkiness and softness and quite comfortable. The process comprises the steps of selecting bamboo fibers and wood fibers extracted from wood in a sustainable development forest area, and respectively putting the bamboo fibers and the wood fibers into a digester for cooking and pulping; then sequentially performing washing, performing pulping by a pulping machine, mixing wood dissolving pulp and bamboo dissolving pulp, performing dipping in a dipping barrel filled with alkali liquor, performing squeezing by a squeezer, adding carbon disulfide by a yellowing machine for yellowing, performing grinding, performing filtering, feeding a filtered material into a spinning machine for spinning, performing drafting, refining and desulfurizing, and performing drying to obtain viscose fibers; blending the obtained viscose fibers and regenerated polyester into yarns, wherein the weight ratio of the viscose fibers to the regenerated polyester fibers is 1:(0.6-0.9); and forming a blank by weaving on a circular knitting machine, and performing cylinder matching, end stitching, dyeing and rinsing, dehydration, slitting, high setting, dyeing, dehydration, cloth tidying, baking setting, napping, finished product setting and packaging,so as to obtain the finished fabric.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a production method of viscose fiber knitted fabrics. Background technique [0002] Viscose fiber is a man-made fiber and one of the earliest chemical fibers put into industrial production, mainly made of regenerated cellulose or wood pulp. Because of its good hygroscopicity, comfortable wearing and excellent spinnability, it has been widely welcomed by garment manufacturers and consumers. Although there are many advantages, the production process of viscose fiber has the same impact on the environment as other textile products that cannot be ignored. The raw material mainly comes from wood, and if it is not controlled, deforestation will have a devastating impact on ancient forests and endangered tree species. In addition, the bulkiness and softness of the viscose fiber made by the traditional method are still lacking. Contents of the invention [0003] In view of t...
