Problems solved by technology

The functional fibers widely used at present are generally prepared by adding chemical reagents or minerals. Most of the chemical reagents or minerals have certain side effects or harmful radiation pollution, so their effectiveness and safety are greatly reduced.
And its content is very unstable, can not achieve the purpose of real functionalization of fiber
In addition, the patent application No. 200410013428.6 published by Wuhan Institute of Science and Technology is "A Modified Fiber of Traditional Chinese Medicine and Its Manufacturing Method". Extremely restrictive cannot be applied in most fiber varieties

Embodiment 1

[0031] Weigh the traditional Chinese medicine honeysuckle to remove impurities, cut, pulverize, rub, and screen to obtain 2 kg of crude honeysuckle with a length of less than 5 mm and mix them with 20 kg of cotton pulp into an impregnation barrel for impregnation. The process conditions are as follows: the concentration of caustic soda for one impregnation is 240g / l, the temperature is 55°C, the time is 50 minutes, the concentration of porridge is 4%, and 1% of impregnation aid LV-3 is added. Carry out secondary impregnation through pressing and pulverizing process, caustic soda concentration is 170g / l, temperature is 45 ℃, time is 30 minutes, and the concentration of porridge is 3.5%. After pressing, the alkali fiber contains 30% of methyl fiber and 14.4% of alkali. After 4 hours of aging, the viscosity of alkali cellulose cupro ammonia reaches 0.0055Pa.s, and the yellowing process parameter CS 2The addition coefficient is 36%, the initial temperature is 18°C, the final temp...

Embodiment 2

[0033] Take 0.5 kg of the screened Acanthopanax senticosus dry powder, mix with 30 kg of alkali cellulose with a methylcellulose content of 30%, and blend to make glue. Yellowing process parameter CS 2 The addition coefficient is 34%, the initial temperature is 21°C, the final temperature is 29°C, the time is 80 minutes, and the wet method is used for yellowing. Dissolved at 17-18°C for 150 minutes, filtered through three times, defoamed and matured for 8 hours. The spinning conditions are that the aperture of the spinneret is 0.06, the spinning speed is 40 m / min, the viscose index is: 8.7% of cellulose, 5.7% of alkali, 33 seconds of viscosity, and 12 ml of maturity. Spinning and drawing process parameters are: acid bath sulfuric acid concentration 133g / l, temperature 48°C, zinc sulfate content 9g / l, sodium sulfate content 335g / l, draw ratio 2.32, plasticizing bath temperature 85-99°C. Post-treatment is carried out after cutting, and the post-treatment process parameters are...

Embodiment 3

[0035] Take the crushed and ground tomato juice, filter it with a 100-mesh steel mesh, take 0.5 kg of its juice, add it to 50 L of primary dissolving viscose and mix it, dissolve and grind it at 20°C for 160 minutes to obtain dissolving glue. After three times of filtration, degassing and aging for 15 hours. The spinning conditions are that the aperture of the spinneret is 0.06, the spinning speed is 45 m / min, the viscose index is: 8.7% of cellulose, 5.5% of alkali, 35 seconds of viscosity, and 9.5ml of maturity. Spinning and drawing process parameters are: acid bath sulfuric acid concentration 125g / l, temperature 50°C, zinc sulfate content 12g / l, sodium sulfate content 325g / l, draw ratio 2.26, plasticizing bath temperature 80-98°C. Post-treatment after cutting, the post-treatment process parameters are: first washing temperature 35°C, alkali content in desulfurization bath 6.5g / l, temperature 78°C, second washing temperature 50°C, third washing temperature 70°C, oil bath conc...

Abstract

The invention discloses a traditional Chinese drug component containing functional viscose fiber and its manufacturing method. It is made up of traditional Chinese drug material, semi-finished products, finished products, part of dregs of decoction, and viscose fiber. Its components content is fiber: 85-99.9%, traditional Chinese drug: 0.1-15%. Its manufacturing method includes the following steps: dipping, mellowing, sulphidizing, dissolving, mixing, filtering, defoaming, ripening, spinning fore raw liquor mixing, traditional Chinese drug fiber spinning and drafting, and fiber after-treatment. Its traditional Chinese drug content can reach 10%. Thus the fiber has more effective health protection, sickness prevention, and auxiliary therapy. Thus it is fit for making underclothes, bedding, medical component, and so on.

Description

technical field [0001] The invention relates to chemical fibers, in particular to viscose fibers containing traditional Chinese medicine ingredients and a preparation method thereof. Background technique [0002] Viscose fiber includes ordinary viscose long and short fiber, high wet modulus viscose fiber, strong viscose fiber, etc. It is a textile material with a wide range of uses, especially for the preparation of various clothing, bedding, medical supplies and health care supplies. In order to make viscose fiber more widely used, it is often necessary to modify it, such as coating in the fiber or on the surface of the fiber, adding materials that have health effects on the human body, such as flame retardants, anti-ultraviolet agents, Antibacterial agents, etc., form a functional fiber, so that the prepared fabric has special functions. Currently widely used functional fibers are generally prepared by adding chemical reagents or minerals. Most of the chemical reagents or...
