Embodiment 1

[0028] A spinning solution with hemostatic function, in parts by weight, comprising the following components:

[0029]

[0030] Its preparation method comprises the following steps:

[0031] (1) Mix and stir 4 parts of sodium stearate, 2 parts of acetic acid and deionized water evenly, add 20 parts of regenerated cellulose fiber knitted fabric, continue stirring, add ammonia water to adjust the pH to 10, ultrasonicate for 2 hours at 400W power, add excess Ethanol, obtain mixed dispersion liquid;

Abstract

The invention discloses a novel spinning solution with a hematostatic function. The novel spinning solution comprises the following components in parts by weight: 20-25 parts of modified regenerated cellulose, 10-15 parts of carboxymethyl chitosan, 2-5 parts of liquid paraffin, 1-3 parts of span-80, 5-15 parts of bletilla striata gelatin, 10-15 parts of absolute ethyl alcohol and 40-50 parts of deionized water. The invention further discloses a preparation method of the spinning solution. The spinning solution disclosed by the invention is uniform in dispersion and good in spinnability, and has good hematostatic property and good biocompatibility; and the prepared textile is good in wet strength, simple in preparation method, low in raw material price, and low in cost.

Description

Technical field: [0001] The invention relates to the technical field of spinning, in particular to a spinning solution with a hemostatic function. Background technique: [0002] Modified regenerated cellulose is a kind of regenerated cellulose derivative, which has been used in many industries such as medical industry, but the hemostatic ability of modified regenerated cellulose is relatively poor, and the hemostatic time is relatively long. In addition, the regenerated cellulose Toxic solvents are often used in modification, and the process is complicated, which limits its application. [0003] Carboxymethyl chitosan is a chemical compound that has appeared in recent years. It is stable in nature, has certain antibacterial and anti-infective capabilities, and has good biocompatibility. Bletilla striata gum is extracted from plants and has good water solubility and Biocompatibility, good hemostatic effect, and no toxic side effects. [0004] Chinese patent (CN201410280617....
