Description
Technical field
The present invention relates to a kind of antibacterial Fang Jie Xian functional fibre and preparation method thereof, belong to the chemical fibre production field that adds antibacterial anti-mange functional component melt spinning.
Background technology
The method for the treatment of Jie Xian is divided into external application and for oral administration, applies the ointment outward, and treatment cycle is long, has not only limited patient's freedom but also has been easy to the clothing of making dirty, uncomfortable especially when perspiration, and spatter property is very poor peculiar smell, very inconvenient in public; And endo-medicine, though spatter property has been got well human body has been had to larger side effect; And during treatment skin disease, for timely germicide-acaricide, improve skin disease cure rate and reduce recurrence rate, to often adopt the sterilizations such as traditional poach and bleaching agent immersion to carry out disinfection to clothing bedding and kill mite, these work are very heavy, but also often cause clothing, the dye decolored variable color of sheet.People wish to find a kind of new material preparation method, have both guaranteed that material had lasting good antibacterial control Jie Xian effect, reduce skin disease recurrence rate, alleviate the workload that mite is killed in sterilization, also will guarantee that material preparation cost is low, safe, effective.
Chinese Patent Application No. CN99119345.8 discloses a kind of formula for the treatment of scabies ointment, thinks that borax has an astriction to mucocutaneous, has the drug effect that suppresses toadstool; Sulphur can kill parasite with it, softening epidermis, and the drug effect of recovery organization function is as the principal component of ointment, and the efficiency of the antibacterial therapy scabies of this formula reaches more than 98%, and cure rate is more than 95%; Chinese Patent Application No. CN201010270007.7 discloses sulfur-bearing 8%, the medical ointment prescription of the antibacterial therapy scabies that a kind of curative effect of borax 30% is fast and good, Chinese Patent Application No. CN201110321199.4 discloses and a kind ofly with sulphur and borax, has done the pharmaceutical formulation that main component for treating scabies also has good result.
Through our retrieval, the method of the medicine for the treatment of scabies Xian and resin being made to the antibacterial functional fibre of preventing and treating mange of master batch direct fabrics gained is few, what know most is Nano Silver finishing method, such as Chinese Patent Application No. CN201110398704.5, this fibrid has poor, the not wash fast defect of the fastness of adhesion, preparation cost is high in addition, has limited its promotion and application.
Chinese Patent Application No. CN200710190766.0 discloses a kind of anti-mite polypropylene fiber making with melt spinning method, it is mite-proofing and antimicrobial finishing agent SCJ-998 that this patent is only mentioned functional additive, and this patent particle diameter of mentioning finishing agent SCJ-998 will be strict controlled in and is less than 50nm with interior nano-scale particle, and only mention with polypropylene fibre resin alloy and be spun into polypropylene fiber silk, fail to apply on some chemical fibres such as terylene, the method preparation cost is higher, preparation technology is harsher, functional additive is limited, and carrier material is more limited.
Summary of the invention
The present invention will solve finishing method and prepare high, the not washable shortcoming of antibacterial Fang Jie Xian textile material cost, and the antibacterial Fang Jie Xian functional fibre adaptability that this preparation method obtains is wider, cost is low, it is more lasting to prepare simple, washable, antibacterial control Jie Xian effect.
The principle of screening function additive of the present invention is: (1) can be used as effectively antibacterial, prevent and treat mange and kill the principal component of acarid medicinal mixture, (2) heat resistance is good, chemical stability is good, is applicable to melt spinning.The drug ingedient that meets at above 2 can be as functional additive of the present invention, and from retrieved patent and paper, sulphur and borax etc. can be used as safety, antibacterial, the main drug ingedient of preventing and treating mange efficiently.
Preparation method of the present invention comprises: (1) prepares antibacterial Fang Jie Xian functional agglomerate: sublimed sulfur and borax are mixed with fibre resin by certain percentage by weight, pour mixed material into double screw extruder again, under uniform temperature condition, melt extrude, cooling, pelletizing, make antibacterial Fang Jie Xian functional agglomerate; (2) spinning: the direct melt spinning of this functional agglomerate or its are mixed to rear melt spinning by a certain percentage with his resin slicer.
As a modification of the present invention, can change as required the shape of spinnerets, such as changing the spinnerets of circular port into, can spin the round fiber of cross section, change other different in nature structure spinnerets into, can correspondingly spin the polymorphic structure fibers such as trilobal cross or hollow type.
As a modification of the present invention, can adopt as required the composite construction fibers such as Compound spinning silk spinning skin-core structure, island type structure, using the component containing functional component as skin component or sea component, another component plays the effect of support structure as Xin He island component.
Sulphur and borax at such fiber surface have played inhibition toadstool and have killed parasite, softening epidermis, the effect of recovery organization function.After rinsing 20 times, this fibrid inhibition zone width≤1mm (much smaller than standard-required≤5mm), security is good, bacteriostasis rate to staphylococcus aureus (ATCC6538) reaches more than 95%, the bacteriostasis rate of Escherichia coli (8099) reaches more than 90%, the bacteriostasis rate that white is read coccus (ATCC10231) reaches more than 95%, and the requirement that is all above standard of its antibacterial effect, reaches more than 90% the killing rate of mange acarid.
Usefulness of the present invention is: under the prerequisite of physicochemical characteristics that does not change fiber, efficiently solve that finishing method fastness is poor, not wash resistant, defect that cost is high 1.; 2. this fibrid has the lasting good antibacterial effect that scabies Xian kills mite of preventing and treating, and can solve when treating scabies Xian skin disease because sheet clothing is failed the timely thorough disinfection mite of going out, and be prone to the phenomenon of recurrence; 3. the mechanical performance of function powder front and back fiber is added in test, and experiment shows that the draftability of fiber, intensity do not make significant difference, and function powder sulphur and borax are evenly distributed on fiber cross section, is applicable to making various clothes, dress ornament; 4. technique is simple, low cost of manufacture.
