Abstract
The invention relates to a preparation method of a soluble hemostasis textile material, comprising the following steps of: activating natural cellulose textile material with ethanol solution containing sodium hydroxide; treating the natural cellulose textile material with chloroacetic acid reaction solution; regulating pH of the natural cellulose textile material with hydrochloric acid solution; washing the natural cellulose textile material with the ethanol solution; and drying the natural cellulose textile material. The invention has the beneficial effect that the obtained natural cellulose textile material has hemostasis function, can promote wound healing and avoid adhesion and is dissolved into micromolecule cellulose salt when the material is wet.
Description
Technical field
The present invention relates to a kind of preparation method of soluble hemostyptic textile material.
Background technology
Hemostatic material in medical use is a kind of important medical dressing commonly used, has that use amount is large, the characteristics of wide application.But conventional hemostatic gauze can cause the problems such as environmental pollution of change dressings aggravation patient suffering, discarded gauze.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of preparation method of soluble hemostyptic textile material.
The present invention solves the technical scheme that its technical problem adopts: a kind of preparation method of soluble hemostyptic textile material may further comprise the steps:
A, with the native cellulose textile material with 40～60 ℃ of 60～75% ethanolic solutions activation that contain 2～3mol/L NaOH 3～5 hours, the native cellulose textile material is cotton fiber, bamboo fibre or xylon;
B, will process 4～8 hours with 3～4mol/L chloroacetate reaction liquid of 40～60 ℃ through the native cellulose textile material of overactivation among a, chloroacetate reaction liquid is the chloroacetic acid solution that contains ethanol or acetone;
C, treated native cellulose textile material among the b is regulated pH to 6.5～7.5 with hydrochloric acid solution;
D, with the native cellulose textile material that obtains among 60～95% ethanolic solutions washings c, until salt content≤3%;
E, with the oven dry of the native cellulose textile material that obtains among the d, bake out temperature is 80～120 ℃.
The invention has the beneficial effects as follows: the native cellulose textile material that makes has hemostatic function, promotes wound healing, avoids Adhesion formation, meets water and is dissolved as little molecule cellulosate.
The specific embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention rather than limitation of the invention further.
Embodiment 1:
A, with the native cellulose textile material with 40～60 ℃ of 60% ethanolic solutions activation that contain 2mol/L NaOH 3 hours, the native cellulose textile material is cotton fiber, bamboo fibre or xylon;
B, will process 4 hours with 40～60 ℃ 3mol/L chloroacetate reaction liquid through the native cellulose textile material of overactivation among a, chloroacetate reaction liquid is the chloroacetic acid solution that contains ethanol;
C, treated native cellulose textile material among the b is regulated pH to 6.5～7.5 with hydrochloric acid solution;
D, with the native cellulose textile material that obtains among the 60% ethanolic solution washing c, until salt content≤3%;
E, with the oven dry of the native cellulose textile material that obtains among the d, bake out temperature is 80～120 ℃.
Embodiment 2:
A, with the native cellulose textile material with 40～60 ℃ of 75% ethanolic solutions activation that contain 3mol/L NaOH 5 hours, the native cellulose textile material is cotton fiber, bamboo fibre or xylon;
B, will process 8 hours with 40～60 ℃ 4mol/L chloroacetate reaction liquid through the native cellulose textile material of overactivation among a, chloroacetate reaction liquid is the chloroacetic acid solution that contains acetone;
C, treated native cellulose textile material among the b is regulated pH to 6.5～7.5 with hydrochloric acid solution;
D, with the native cellulose textile material that obtains among the 95% ethanolic solution washing c, until salt content≤3%;
E, with the oven dry of the native cellulose textile material that obtains among the d, bake out temperature is 80～120 ℃.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
