Abstract

The invention relates to a wet spinning technology applicable to preparing livistona chinensis cellulose regenerated fiber. The technology comprises preparation of a spinning solution obtained by dissolving livistona chinensis leaf cellulose regenerated fiber into an anhydrous lithium chloride/dimethylacetamide mixed solvent and wet spinning technology performed within the condition range; the spinning solution temperature of 35-95 DEG C, the coagulating bath temperature if 15-45 DEG C, the dimethylacetamide volume concentration in a coagulating bath is 0-30%, the temperature of a stretch bath is 30-60 DEG C, and the stretching ratio is 1.2-1.8 times. The livistona chinensis cellulose regenerated fiber prepared through the wet spinning technology within the condition range has the good mechanical property and moisture regain, and the livistona chinensis cellulose regenerated fiber will become novel cellulose regenerated fiber.

Description

technical field [0001] The invention relates to a wet spinning process after dissolving palm leaf cellulose with anhydrous lithium chloride / dimethylacetamide solvent system, belongs to the technical field of plant regenerated fiber, in particular to a kind of process suitable for preparing palm leaf cellulose Wet spinning process of regenerated fiber. Background technique [0002] In the textile industry, cellulose regenerated fiber has always been valued by people because of its rich resources, environmental friendliness, and comfortable products. Although its consumption proportion is not as high as that of synthetic fibers in recent years, due to the increasing depletion of coal and oil, and the serious "white pollution" caused by the non-degradable waste of synthetic fiber products is becoming more and more serious, and restricted by the area of ​​cultivated land, the output of virgin fibers It is also subject to certain restrictions, and the demand for fiber is constan...
