Problems solved by technology

[0002] Medical cotton is the abbreviation of medical absorbent cotton, which refers to the cotton three-fiber used in the medical and health care industry, such as cotton balls, cotton swabs, alcohol cotton and other disposable sanitary materials; medical cotton is generally made of poor quality below grade 5 Cotton needs to go through a more scientific and reasonable production process before it can produce compounded medical cotton; the existing technology is high-temperature scouring with strong alkali, chlorine bleaching, pickling, oxygen bleaching, and water washing to finally produce medical cotton. There are situations such as long process flow, high energy consumption, polluting the environment, and the impurities in cotton fibers are not easy to meet the standards; at present, medical quilts are widely used in the protection and care of surgical wounds, but with the development of medicine, the simple treatment of wounds The protection and isolation of wound placement can no longer meet the needs of modern medicine; the medical cotton of the prior art still needs to be soaked in iodine or alcohol for anti-inflammatory and treatment, which is time-consuming and laborious, and cannot meet the needs of modern wound treatment.

Embodiment 1

[0020] A kind of graphene medical cotton, adopts cotton loose fiber, graphene, nano-silver and Chinese medicine composition extract to prepare with the weight ratio of 5:1:0.05:5, and described Chinese medicine composition extract is chia seed, Bitter cabbage, flat bud extract.

[0021] The graphene here is nanoscale graphene.

[0022] The extract of the traditional Chinese medicine composition is prepared by mixing 8 parts of chia seeds, 15 parts of bitter herbs and 10 parts of flat buds by weight, and then extracting and concentrating.

[0023] The preparation method of described graphene medical cotton, comprises the following steps:

[0024] 1) Pretreatment of cotton loose fiber: take cotton loose fiber by formula, squeeze into the caustic soda solution of 15 times the weight of cotton loose fiber in the bleaching equipment, the mass percentage concentration of caustic soda solution is 25-30%, and the processing time is 15 -25min; Hoist the processed cotton loose fiber i...

Embodiment 2

[0032] On the basis of Example 1, the extract of the traditional Chinese medicine composition is prepared by mixing 10 parts of chia seeds, 20 parts of bitter herbs and 20 parts of flat buds by weight, and then extracting and concentrating.

[0033] The preparation method of described graphene medical cotton, comprises the following steps:

[0034] 1) Pretreatment of cotton loose fiber: take cotton loose fiber by formula, squeeze into the caustic soda solution of 15 times the weight of cotton loose fiber in the bleaching equipment, the mass percentage concentration of caustic soda solution is 25-30%, and the processing time is 15 -25min; Hoist the processed cotton loose fiber into the high temperature and high pressure yarn cooking pot and scour according to the weight ratio of cotton loose fiber:soft water=1:7~8, add its 0.05~0.1% pectinase by weight in the soft water and hemicellulase; adjust the pH between 7.0 and 7.6, and the scouring temperature is 60-80°C; the scouring t...

Abstract

The invention discloses graphene medical cotton and a preparation method thereof. The graphene medical cotton is prepared from cotton scattered fiber, graphene, nanometer silver and traditional Chinese medicine composition; the traditional Chinese medicine composition extraction liquid is prepared from 8 parts of chia seeds, 15 parts of sow thistle and 10 parts of Gentianopsis barbata according to the weight ratio through extraction and concentration; the preparation method of the graphene medical cotton comprises the following steps of performing constant temperature soaking for 200 to 240min in the traditional Chinese medicine composition after alkaline washing, enzyme boiling and water washing; pouring a sliver ion mixing solution prepared by nanometer silver into the traditional Chinese medicine composition extract to be continuously soaked for 30 to 45 min; performing taking out and freeze drying; finally, mixing the cotton scattered fiber subjected to freeze drying with graphene; obtaining the graphene medical cotton through preparation after the cotton mixing, blowing, combing and screen laying. The graphene medical cotton has good sterilization and anti-bacteria effect, good moisture absorption performance and good heat insulation performance; the metabolism of the tissue cells can be improved; the wound heeling is promoted; the pain relieving, bleeding stopping, itching reliving, detumescence, antiphlogosis and antiallergic effects are achieved; the graphene medical cotton is worth of being popularized in a large range.

Description

technical field [0001] The invention relates to the field of disposable medical supplies, in particular to graphene medical cotton and a preparation method thereof.
