Embodiment 1

[0032] Embodiment 1: take viscose-based fiber as raw material hydrophilic activated carbon fiber and preparation method thereof

[0033] The 1000-denier viscose-based fiber is spun into a cloth with a density of 40 (yarn longitude) and 2 up and 2 down (double-sided weaving) by special machinery. Fully wash the non-woven felt with hot water or boiling water at 40-100°C for 30 minutes, then impregnate copper oxide and zinc chloride catalysts and dry. Under the condition of air medium and 200°C, pre-oxidize for 100 minutes; under the protection of inert gas, carbonize continuously at 850°C for 100 minutes to obtain carbon fibers; activated into hydrophilic activated carbon fibers. Control the pore structure by controlling the activation speed and activation time, that is, control the amount of water vapor during activation to about 50Nm 3 / h (Note: m 3 / h is the unit of the amount of water vapor, N represents the water vapor under the protection of nitrogen, the general writin...

Embodiment 2

[0035] Embodiment 2: take polyacrylonitrile fiber as the hydrophilic active carbon fiber of raw material and preparation method thereof

[0036] The same method as in Example 1 was used to prepare the hydrophilic activated carbon fibers of the present invention, except that the viscose-based fiber filaments were replaced with polyacrylonitrile fiber filaments. Its C weight percentage content is determined to be 92%, and the specific surface area of ​​activated carbon fiber is 1250m 2 / g, the pore volume is 0.75ml / g. Its pore structure and surface properties are shown in Table 2 below.

Embodiment 3

[0038] Embodiment 3: the preparation of tampon product of the present invention:

[0039] Select a piece of hydrophilic activated carbon fiber (cloth shape) of the present invention prepared by the method of Example 1, which is similar in size to an ordinary sanitary napkin, and compress and fold it according to the female physiological structure, and its specification is the diameter Between (12-15) mm (diameter) - length (45-55) mm.

Abstract

A hygienic plug prepared by activated carbon fibre with absorption to target direction has 70-95 wt.% of C content in activated carbon fibre, specific surface area of 700-1500 m2 / g and pore volume of equal or bigger than 0.45ml / g. It can be used to cure women's vaginal disease.

Description

【Technical field】 [0001] The present invention relates to a novel hydrophilic activated carbon fiber material and its preparation method, and the suppository product prepared therefrom for treating women's vaginal diseases, and also relates to the use of the activated carbon fiber material as a drug carrier for burns, scalds and wounds, as well as first-aid bandages, etc. the use of. 【Background technique】 [0002] From the current military medical information, it is known that the former Soviet Union began the research on medical activated carbon fiber (ACF) technology in the 1980s, and listed it as a military secret for more than 10 years in clinical trials in various military hospitals and field hospitals in the former Soviet Union. At present, Russia has officially used it in the field of military medicine, mainly applying this technology to equip field troops and biochemical troops, and the technology is strictly kept secret. Subsequently, the activated carbon fiber ha...
