Abstract
The invention discloses a preparation method of taxus chinensis fibers with high antibacterial activity and belongs to the field of functional fibers. The content of paclitaxel in branches of taxus chinensis is lower, so that the prepared taxus chinensis fibers have poor drug property and poorer antibacterial property. On the basis that the antibacterial property of existing taxus chinensis fibers is kept, the antibacterial property of the fibers is enhanced by adding chitosan-modified monodispersed nano TiO2, the problems that the existing taxus chinensis fibers have poor drug property and the antibacterial property is not lasting are solved, and the application range of the taxus chinensis fibers is enlarged.
Description
Technical field
The preparation method that the present invention relates to a kind of high antibacterial activity Ramulus et folium taxi cuspidatae fiber, belongs to functional fibre field.
Background technology
Taxaceae Taxus (Taxus) plant is that the 3rd discipline Jue loses plant, has survived on earth and has multiplied 2,500,000 years.20 century 70s, Wani etc. extracts, from yewtree, the natural anti-cancer compound paclitaxel that separation obtains, and has the suppression microtubule depolymerization of uniqueness and stablizes micro-pipe effect.The medical value of Chinese yew genus plants causes the great attention of global research institution and pharmacy corporation.Separating from Chinese yew genus plants in 200 Multiple components obtained, Taxane diterpenoids and alkaloid that active anticancer is stronger are especially noticeable.But due to growth of taxol slowly, active constituent content is little in shortage of resources, bark, extraction and application is extremely restricted, therefore, carry out the separation of Ramulus et folium taxi cuspidatae endogenetic fungus and the research of metabolite thereof, open up a new approach by finding cancer therapy drug for the mankind from microorganism angle.
The textile that people's various fibers used in everyday are made is the suitable place of bacteria breed, breeding and propagation.Various antibacterials can breed rapidly when condition is suitable, and fibre variable color not only can be made mouldy, also human body skin can be produced abnormal stimulation and bring out various dermatosis, human lives causes all harm.And Ramulus et folium taxi cuspidatae fiber is suitable for and other fiber, regenerated celulose fibre, combing cotton fibre blending, realize fabric and wear next to the skin softness, comfortable, elastic and good bacteria resistance function, improve the added value of Ramulus et folium taxi cuspidatae fabric, significantly meet people and pursue the needs of high-quality life, scientific and technical innovation is penetrated in townwear, be dissolved in the life staying idle at home of people.Owing to the content of taxol in Ramulus et folium taxi cuspidatae branch is relatively low, so the Ramulus et folium taxi cuspidatae fiber property of medicine of preparation is not enough, antibiotic property is poor.The antibiotic property improving Ramulus et folium taxi cuspidatae fiber is extremely urgent.
Summary of the invention
For the deficiencies in the prior art, present invention is primarily targeted at the preparation method that a kind of high antibacterial activity Ramulus et folium taxi cuspidatae fiber is provided.
For realizing aforementioned invention purpose, the technical scheme that the present invention takes is as follows:
(1) by 3-4 weight portion long-chain fatty alcohol template, 10-19 parts by weight of ethanol, 0.5-2 weight parts water mixed liquor magnetic agitation 5 minutes under room temperature, 2-4 weight portion butyl titanate is dripped with the speed of 1-3 drop/sec, 1-5 weight portion ammonia is dripped after stirring 10 minutes, after magnetic agitation 2 hours, it is added dropwise over the chitosan solution of 15-20wt%, after rotary distillation, residue emulsion is centrifuged after ageing 12 hours, precipitation ethanol and water mixed solution wash 1-3 time, product is placed in 90 DEG C of baking ovens 12 hours, prepares modified dispersed nano TiO2；
(2) by the dispersed nano TiO of 3-5 weight portion2It is dispersed in the ethanol of 20-30 weight portion, is then uniformly added drop-wise in the concentrated pulp of 100 weight portions that Ramulus et folium taxi cuspidatae timber extracts；Uniform stirring also concentrates further at 40-50 DEG C, removes the ethanol in concentrated solution；Then joining in concentrated solution by 3-4wt% sodium hydroxide and 4-7wt% carbamide mixed aqueous solution, wet spinning prepares Ramulus et folium taxi cuspidatae fiber.
Described long-chain fatty alcohol template is at least one in lauryl alcohol, tetradecyl alchohol, hexadecanol.
The Ramulus et folium taxi cuspidatae fiber prepared by aforementioned method, its antibiotic property is up to more than 99%.
Relative to prior art, the present invention is keeping on the basis of existing Ramulus et folium taxi cuspidatae fibre antibacterial, by adding chitin modified mono-dispersed nano TiO2The antibiotic property of fortifying fibre, solves that original Ramulus et folium taxi cuspidatae fibre antibacterial is poor, the unabiding problem of antibiotic property.
Detailed description of the invention
In view of deficiency of the prior art, inventor, through studying for a long period of time and putting into practice in a large number, is proposed technical scheme.Below in conjunction with some case study on implementation, the present invention is further detailed explanation.
Embodiment 1:
By 3 weight portion long-chain fatty alcohol template, 12 parts by weight of ethanol, 2 weight parts water mixed liquors magnetic agitation 5 minutes under room temperature, 3 weight portion butyl titanates are dripped with the speed of 2 drops/sec, 2 weight portion ammonia are dripped after stirring 10 minutes, after magnetic agitation 2 hours, being added dropwise over the chitosan solution of 16wt%, residue emulsion be centrifuged after ageing 12 hours after rotary distillation, precipitation ethanol and water mixed solution wash 2 times, product is placed in 90 DEG C of baking ovens 12 hours, prepares dispersed nano TiO2.By the dispersed nano TiO of 3 weight portions2It is dispersed in the ethanol of 25 weight portions, is then uniformly added drop-wise in the concentrated pulp of 100 weight portions that Ramulus et folium taxi cuspidatae timber extracts；Uniform stirring also concentrates further at 40 DEG C, removes the ethanol in concentrated solution；Then joining in concentrated solution by 4wt% sodium hydroxide and 7wt% carbamide mixed aqueous solution, wet spinning prepares Ramulus et folium taxi cuspidatae fiber.
Embodiment 2:
By 4 weight portion long-chain fatty alcohol template, 19 parts by weight of ethanol, 2 weight parts water mixed liquors magnetic agitation 5 minutes under room temperature, 4 weight portion butyl titanates are dripped with the speed of 3 drops/sec, 5 weight portion ammonia are dripped after stirring 10 minutes, after magnetic agitation 2 hours, being added dropwise over the chitosan solution of 20wt%, residue emulsion be centrifuged after ageing 12 hours after rotary distillation, precipitation ethanol and water mixed solution wash 3 times, product is placed in 90 DEG C of baking ovens 12 hours, prepares dispersed nano TiO2.By the dispersed nano TiO of 5 weight portions2It is dispersed in the ethanol of 30 weight portions, is then uniformly added drop-wise in the concentrated pulp of 100 weight portions that Ramulus et folium taxi cuspidatae timber extracts；Uniform stirring also concentrates further at 50 DEG C, removes the ethanol in concentrated solution；Then joining in concentrated solution by 3wt% sodium hydroxide and 6wt% carbamide mixed aqueous solution, wet spinning prepares Ramulus et folium taxi cuspidatae fiber.
