Abstract
A kind of Chloranthus glaber efficient antibacterial antiviral cellulose fibre of present invention offer, the fiber, the content of chitosan functional components compound particle is 9.5 9.7%, and the content of silicic acid composite colloid is 2 3.5%；The present invention also provides a kind of preparation method of Chloranthus glaber efficient antibacterial antiviral cellulose fibre, including prepares chitosan functional components compound particle, prepares silicic acid composite colloid, blending, spinning moulding.The present invention reduces the loss or loss of functional components in fiber manufacturing process；Fiber prepared by the present invention, functional components are distributed in fibrocortex and surface portion；Fiber prepared by the present invention, is firmly combined with the functional components that graininess is embedded in fibrocortex or surface with fiber, is lost in washing and friction process few；In fiber of the present invention, influenza A virus and influenza B virus can be effective against, also there is higher inhibiting rate to staphylococcus aureus, Candida albicans, typhoid bacillus.
Description
Technical field
The present invention relates to a kind of viscose rayon, particularly a kind of Chloranthus glaber efficient antibacterial antiviral cellulose fibre and its system
Preparation Method, belongs to textile technology field.
Background technology
The development of functional fibre is the symbol of modern fiber science progress.Functional fibre, fibre in differentiation and high-performance are fine
The technological innovation for developing into traditional textile industry of dimension, creates advantage to the conversion of high-tech industry, is human lives
The raising of level contributes.Functional fibre refers in addition to the physical and mechanical properties that general fiber has, also with certain
Plant the tencel of specific function.
Radix Isatidis, is a kind of excellent Chinese medicine, with antibacterial, effect that is antiviral, antitumor, improving immunologic function；
Isatis root extract is added in viscose rayon, the textile with healthcare functions such as antiviral, raising immunity is prepared,
Meet the popular demand to the product with health care function of present society.
Chloranthus glaber, is Chloranthaceae perennial evergreen undershrub, is commonly called as spice all over the mountain, kwan-yin tea, nine joint flower, elder etc..
Its form is beautiful, four seasons fragrance, with high medicinal, edible and ornamental value；Complete stool hyoscine, can clearing heat and detoxicating, wind-dispelling
Promoting blood circulation, swelling and pain relieving, anti-inflammation.
Peppermint, is one of Chinese conventional Chinese medicine, and it is pungent cool property sweating antipyretic medicine, control influenza, headache, hot eyes,
Body heat, throat, gum such as swell and ache the disease, and external application can control neuralgia, pruitus, fash and eczema etc., and modern pharmacological research is found
The involatile constituent of peppermint has anti-inflammatory, it is antibacterial the effects such as.
Typically the extract of Radix Isatidis, Chloranthus glaber, peppermint is added in fiber respectively in the prior art, feature is prepared
Fiber, existing functional fiber has the following disadvantages：
（1）In fiber manufacturing process, isatis root extract, Herba Pileae Scriptae extract, the extract of peppermint soluble in water are caused
It is lost in, is also easy to be caused damage by soda acid destruction；
（2）It is usually that functional components and spinning solution are blended in the prior art, is then sprayed into coagulating bath and carries out spinning, because
The distribution of functional components in the fibre is random, that is to say, that a large amount of functional components can be distributed in the sandwich layer of fiber, point
Cloth fiber surface or cortex it is less；Because the extract of isatis root extract, Herba Pileae Scriptae extract, peppermint is contact
Anti-bacteria and anti-virus, so the functional components for being only distributed in fibrocortex or surface can just play effect, therefore feature into
Divide and be largely distributed in inside core fiber layer, cause a large amount of wastes, can also increase production cost；
（3）The functional components of fiber surface will also result in loss in washing and friction process, and then drop low-fiber antibacterial
Antiviral effect.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of Chloranthus glaber efficient antibacterial antiviral cellulose fibre and its preparation side
Method, to realize following goal of the invention：
（1）In fiber manufacturing process, isatis root extract, Herba Pileae Scriptae extract, the loss of the extract of peppermint or damage are reduced
Lose；
（2）Fiber prepared by the present invention, isatis root extract, Herba Pileae Scriptae extract, the extract profiles of peppermint are in fibrocortex
And surface portion, and outermost surface material has very strong adsorptivity；
（3）Fiber prepared by the present invention, is firmly combined with the functional components that graininess is embedded in fibrocortex or surface with fiber,
It is lost in washing and friction process few.
In order to realize foregoing invention purpose, the technical solution adopted by the present invention is：
A kind of Chloranthus glaber efficient antibacterial antiviral cellulose fibre, the fiber, chitosan-functional components compound particle contains
Measure as 9.5-9.7%, the content of silicic acid composite colloid is in 2-3.5%.
The following is the further improvement to above-mentioned technical proposal：
The chitosan-functional components compound particle, including chitosan, functional components, poly-quaternary ammonium salt；
The functional components, are isatis root extract, Herba Pileae Scriptae extract, the compound of the extract of peppermint；
The isatis root extract, Herba Pileae Scriptae extract, the mass ratio of the extract of peppermint are 3:1:2；The Radix Isatidis is carried
Thing, Herba Pileae Scriptae extract, the quality sum of the extract of peppermint are taken, the mass ratio with chitosan is 1:3；The poly-quaternary ammonium salt
Mass ratio with chitosan is 1:3.8-4.1.
A kind of preparation method of Chloranthus glaber efficient antibacterial antiviral cellulose fibre, including prepare chitosan-feature into
Divide compound particle, prepare silicic acid composite colloid, blending, spinning moulding.
It is described prepare chitosan-functional components compound particle, by isatis root extract, Herba Pileae Scriptae extract, peppermint
Extract is dissolved in pure water, obtains the functional components solution that mass concentration is 1.4-1.6mg/mL；Functional components are molten
During liquid adds mass concentration as 0.7-0.9mg/mL chitosan-acetic acid solution using 18-22mL/h speed, mixing speed is controlled
For 350-450r/min, poly-quaternary ammonium salt is added, filtering, deaeration after then stirring obtain the shell containing functional components and gathered
