Abstract

The invention discloses a production method of a carex meyeriana fiber. The production method adopts the following process flow: taking carex meyeriana raw grass, boiling, carrying out primary processing, carrying out pre-degumming treatment by an ultrasonic wave, carrying out primary washing, carrying out alkali oxidation and degumming bath, pickling, carrying out secondary washing, drying, feeding oil, opening and carding to obtain the carex meyeriana fiber, wherein water is used as a medium in the step of the pre-degumming treatment by the ultrasonic wave, when the frequency is 28-40HZ and the temperature is 50-70 DEG C, the pre-degumming treatment by the ultrasonic wave is carried out for 60-90 minutes, and NaOH is added when the treatment is carried out within 20-30 minutes so as to enable the alkali concentration of the solution to reach 5-15g / l; in the step of alkali oxidation and degumming bath process, carex meyeriana can be put in an alkali oxidation extracting solution to enable the temperature to rise to 90-100 DEG C, heat preservation and boiling are performed for 1-2 hours; the alkali oxidation extracting solution is prepared from the following ingredients: 6-9g / l of sodium hydroxide, 8-12g / l of hydrogen peroxide, 2-4% of sodium polyphosphate serving as an additive of carex meyeriana mass, 2-4% of magnesium sulfate and 1-3% of sodium sulfite.

Description

technical field [0001] The invention relates to textile material technology, in particular to a production method of ulagrass fiber. Background technique [0002] Ulagrass is one of the "Three Treasures of Northeast China". It is loved by everyone because of its unique cold-proof and warm-keeping properties and natural antibacterial and deodorizing properties. At present, ulagrass is mainly used in the fields of ulagrass insoles, ulagrass herbal pillows, ulagrass waist protectors, etc., and the precious resources have not been well utilized. [0003] The production of ulagrass fiber mainly includes two parts: degumming and post-treatment, among which degumming is the key link in extracting ulagrass fiber. There are two methods for the existing degumming technology: one is the alkali boiling method (see "A Production Process and Product of Ulagrass Fiber Silk (Application No. 200410010645.X)"). High-temperature and high-pressure alkali cooking method is used to extract Ulag...
