Abstract

The invention discloses a refined preparation method of a Carex meyeriana fiber. The preparation method adopts the following technology: preparing a Carex meyeriana straw, dipping in water, cooking in water, carrying out preliminary processing, carrying out alkali treatment, washing with water, and carrying out bio-enzyme treatment, alkali-oxygen treatment, bath treatment, afterwashing with water, air drying and filament separation, thus obtaining the Carex meyeriana fiber. An alkali treatment technology is that the dosage of sodium hydroxide is 6-10g / L, and the dosage of urea is 2-4% of the mass of straw. In a bio-enzyme treatment technology, pectinase is adopted for degumming treatment. An alkali-oxygen one-bath technology is characterized in that 4-10g / L of sodium hydroxide, 2-8g / L of hydrogen peroxide and 1-3% of sodium sulfite are adopted, temperature is raised to 90 DEG C from room temperature, and constant temperature time is 30-90min. The fineness of the extracted Carex meyeriana fiber is 40-80mu m, and intensity is 110-230MPa. The problems of complexity in operation, long time consumption, environment pollution, poor fiber processing effect in a traditional preparation method of the Carex meyeriana fiber are solved, and an extraction process has the advantages of simple technology, good fiber performance and the like, and is clean and environmentally friendly.

Description

technical field [0001] The invention relates to textile material technology, in particular to a refined preparation method of ulagrass fiber. Background technique [0002] Ulagrass is one of the only two plants in the plant world that can resist fungal erosion and parasitic ability throughout its life. For hundreds of years, farmers in Northeast China have always needed a pair of shoes covered with ulagrass during the winter, which played a very good role in preventing cold and keeping warm. Because of its unique function of keeping warm, breathable, sweat-absorbing, moisture-proof, cold-proof, and antibacterial, it was once called one of the "Three Treasures of Northeast China" by the world. Ulagrass fiber is the fiber extracted from Ulagrass, which is of great value for its development and utilization. At present, most of the ulagrass fiber products that have been developed are relatively rough, and there are few applications in the textile field, especially in products ...
