Embodiment 1

[0022] A kind of stock solution coloring method prepares the method that loads curcumin polyacrylonitrile fiber:

[0023] The first step is to prepare spinning dope. First prepare the polyacrylonitrile spinning stock solution according to the existing technology, wherein the dry solid content A of polyacrylonitrile is 99 parts by weight, then add curcumin and drug transdermal absorption accelerator into the spinning stock solution and stir evenly, The dry solid amount B that adds curcumin is 0.5 weight part, and the drug transdermal absorption accelerator that adds is oleic acid, and dry solid amount C is 0.5 weight part, and analytical pure N, N-dimethylacetamide (DMAc) aqueous solution is used as Solvent, D is 400 parts by weight, (A+B+C): (A+B+C+D)=20%.

[0024] The second step is to make polyacrylonitrile fiber from the spinning stock solution containing curcumin and drug transdermal absorption accelerator, adopt wet spinning process, and use 50% N,N-dimethylacetamide aqu...

Embodiment 2

[0026] In the present embodiment, the dry solid content A of polyacrylonitrile is 85 parts by weight, then curcumin and drug transdermal absorption accelerator are added in this spinning dope and stirred evenly, the dry solid content B of adding curcumin is 10 parts by weight part, the drug transdermal absorption accelerator added is oleic acid, and the dry solid content C is 5 parts by weight, and analytically pure N,N-dimethylacetamide (DMAc) aqueous solution is used as solvent, and D is 355 parts by weight, (A+ B+C): (A+B+C+D) = 22%. The dry-jet wet-spinning process is adopted, the 50% N,N-dimethylacetamide aqueous solution at 5°C is used as the coagulation bath, the three-stage drafting is carried out, and the bright yellow drug-loaded fiber is finally made into a winding roller. Other methods are the same as in Example 1.

Embodiment 3

[0028] In the present embodiment, the dry solid content A of polyacrylonitrile is 80 parts by weight, then curcumin and drug transdermal absorption accelerator are added in this spinning dope and stirred evenly, the dry solid content B of adding curcumin is 15 parts by weight part, the drug transdermal absorption accelerator added is azone, and the dry solid amount C is 5 parts by weight, and the analytically pure N,N-dimethylacetamide (DMAc) aqueous solution is used as a solvent, and D is 456 parts by weight, (A+ B+C): (A+B+C+D) = 18%. The dry-jet wet-spinning process is adopted, the 50% N,N-dimethylacetamide aqueous solution at 5°C is used as the coagulation bath, the three-stage drafting is carried out, and the bright yellow drug-loaded fiber is finally made into a winding roller. Other methods are the same as in Example 1.

Abstract

The invention discloses a method for preparing a curcumin-loaded polyacrylonitrile fiber by a dope dyeing method. A wet spinning technology, a dry spinning technology or a dry-jet wet spinning technology can be adopted by a spinning solution which is prepared from polyacrylonitrile, curcumin, a skin penetration enhancer and a solvent; the prepared fiber is beautiful yellow, and can be continuously used directly as a colored fiber without dyeing processing; the color fastness is greater than or equal to 4-5 grades; the method is applied to a drug-loaded functional fiber, has a drug sustained-release effect, and is convenient to medicate and small in side effect; and the curcumin-loaded polyacrylonitrile fiber has weaving mechanical property and can be woven into a fabric.

Description

technical field [0001] The invention relates to a method for preparing curcumin-loaded polyacrylonitrile fibers by a stock solution coloring method, and belongs to the cross field of biomedicine and material processing technology. Background technique [0002] Curcumin (curcumin) is a plant polyphenol extracted from the rhizome turmeric of the ginger plant (Curcuma Longa L.), and its molecular formula is C 21 h 20 o 6 , the molecular weight is 368.39. Studies in recent years have shown that curcumin has a wide range of pharmacological effects, such as anti-oxidation, anti-tumor, anti-ischemia, lowering blood lipids, etc., and has low toxicity. It also has the functions of protecting the kidney, inhibiting pulmonary fibrosis, inhibiting liver fibrosis, and helping muscle damage repair , treating cataracts, anti-parasitic diseases, multiple pharmacological effects, and less toxic and side effects, safe to use, and has a good clinical application prospect. At the same time,...
