Embodiment 1

[0019] Embodiment 1: a kind of medical fiber that gelatin, bamboo fiber mixes, is made with bio-based as raw material, wherein the weight percent of each part raw material is:

[0020] Gelatin: bamboo fiber = 1: 9.

[0021] The medical fiber with this weight percentage has good air permeability, water absorption, strong wear resistance and good hemostatic effect.

Embodiment 2

[0022] Embodiment 2: a kind of medical fiber that gelatin, bamboo fiber mixes, is made with bio-based as raw material, wherein the weight percent of each part raw material is:

[0023] Gelatin: bamboo fiber = 3:7.

[0024] The medical fiber with this weight percentage has good air permeability, water absorption, strong wear resistance and stronger hemostatic effect.

Embodiment 3

[0025] Embodiment 3: a kind of medical fiber that gelatin, bamboo fiber mixes, is made with bio-based as raw material, wherein the weight percent of each part raw material is:

[0026] Gelatin: bamboo fiber = 2:8.

[0027] The ratio of this embodiment is reasonable, the advantages of the two raw materials are more obvious, and the toughness and elasticity of the medical fiber are better.

Abstract

The invention discloses a gelatin and bamboo fiber mixed medical fiber and a preparation method thereof. The medical fiber is prepared from bio-based raw materials, specifically the raw materials gelatin and bamboo fiber are in a weight percentage of 1-3:7-9. A gelatin solution is prepared by enzyme method, neutral protease is employed for leather decomposition, then a sol process is carried out to obtain the gelatin solution. A wet process fiber making technology is adopted, a saturated sodium chloride solution is used as the coagulation bath, a nozzle with an aperture of 0.08 and a hole number of 100 is selected for spinning so as to obtain a gelatin and bamboo fiber product. The gelatin and bamboo fiber mixed medical fiber can be made into medical hemostatic gauze and other medical dressings, and has hemostatic, natural antibacterial and bacteriostatic efficacy. The method has the characteristics of scientific and reasonable steps, mature technology, and low production threshold, and can be popularized and used on a large scale.

Description

technical field [0001] The invention relates to a preparation method of a bio-based medical fiber, which belongs to the field of medical materials. Background technique [0002] Gelatin is a fat-free, high-protein product and does not contain cholesterol. It is a natural nutritional food thickener. At the same time, gelatin has the effect of stopping bleeding in medicine. It is a good material for medical use, but gelatin is generally used It is used in the shell of capsules and is rarely used in medical fibers. [0003] Bamboo fiber is a good material for medical fibers. It has good air permeability, water absorption, strong wear resistance, natural antibacterial, antibacterial, and deodorant. If gelatin is added to the bamboo fiber, the fiber will have the effect of hemostasis, which can be used in medical treatment as hemostatic gauze, etc., but the existing technology has not yet achieved this step. [0004] Therefore, those skilled in the art are devoting themselves t...
