Said invention has advantages of high stretching strength, break down extensibility, washing resisting, folding resisting and high temperature resisting.
Description
Technical field
A kind ofly weave medical fibre material and the manufacture method thereof that gauze is used, belong to field of medical materials.
Background technology
The doctor will check the used gauze quantity of operation at perioperatively, if discrepancy is arranged, then might be retained in gauze in the patient body, at this moment need to confirm, if common cotton gauze, have no idea whether to leave over gauze and gauze position, can only operate on again and in the patient body, search for, bring huge misery to patient and family members in patient's vitro detection.Therefore,, can whether leave over gauze and confirm the particular location of gauze in patient's vitro detection, will bring convenience, shorten operating time, reduce patient's misery to the doctor by certain instrument if try every possible means in gauze to add some composition.The most frequently used means are to add the composition that some can develop in the gauze under the X-ray irradiation, detecting with the shadowgraph instrument, just can confirm the position of gauze.
No. 92216310 patent proposes a kind of interlayer mode, is matrix with rubber, makes film, in the middle of two membranes, fill the barium sulfate powder, make the thin slice that accompanies barium sulfate, embed in the common gauze, development effect is good, shortcoming also clearly because the barium sulfate powder is unfixing, can be slided in thin slice, often omit, can not wash, gauze is too thick simultaneously, lacks folding property.
No. 94216671 patent proposes a kind of " aseptic medical development gauze ", inserts wire in common gauze, makes simply, and shortcoming is exactly that gauze is too hard, can not fold, also easy Piercing Pain patient.
No. 00118923 patent proposes a kind of application pattern, utilize silica gel, barium sulfate, salt compounded of iodine and vulcanizing agent to be coated on the common gauze and form developing fiber by cold extrusion, heat cure, its shortcoming is a poor heat resistance, and gauze is softening easily, volatilization, not washable when high-temperature sterilization, and foldability is also poor.
No. 94247141 patent proposes a kind of " operation development gauze ", forms with common gauze and the development line that contains developer, and the development line is mixed by natural rubber, barium sulfate and iodine and forms, and shortcoming is can not be high temperature resistant, and is softening easily, and gaseous volatilization is arranged.
No. 99116463 patent is improved at the fibrous material of making gauze, is carrier with polyvinyl chloride, and barium sulfate is made developer, through blend, copolymerization, crosslinked improvement, sprays silk then, stretches, draws, is fixed to filament shape product.Shortcoming is that polyvinyl chloride is to contain cl material, residual Vinyl Chloride Monomer is arranged, human body is caused adverse effect, be unfit to do medical material, part country has made laws and has banned use of pvc material to be used for medical and packaging for foodstuff, and China does packaging material for food in September, 2005 with regard to polyvinyl chloride and proposed query.In addition, this polyvinyl chloride wire is thicker, and is not washable, and bad folding, heat-resisting ability is poor.
It is carrier that No. 200510031410 patent application documents propose with polypropylene, fills barium sulfate and prepares the polypropylene developing fiber for medical use, and the product fiber number is very little, and is very soft, inweaves gauze easily.But because prescription is not good enough, therefore, product is more crisp, and fibre strength is lower, and percentage elongation is also lower.
Summary of the invention
The purpose of this invention is to provide a kind of medical X-ray developing fiber and manufacture method thereof, both development effect was good to accomplish hospital gauze with this kind fiber product braiding, and itself is nontoxic, high temperature-resistant disinfected, and washable folding is folded, and very high strength and percentage elongation are arranged again.
The present invention has three kinds of manufacture methods.The production stage of first method is as follows:
1, get the raw materials ready according to following weight proportion:
Polypropylene chip or powder 30～35% barium sulfate 60～68%
Compatilizer 0.5～3% reinforcing agent 0.5～5%
Flexibilizer 0.1～2% antioxidant 0.1～1%
Polypropylene cooling masterbatch 0.1～2% dispersant 0.1～1%
Polypropylene Masterbatch 0～5%
Compatilizer a kind of in maleic anhydride (MAH), succinyl oxide, the EP rubbers preferably wherein; Reinforcing agent is ethylene-octene copolymer (POE); Flexibilizer is ethylene propylene diene rubber (EPDN) or acrylate rubber; The antioxidant model is a kind of in 1010,3114,330 preferably; Dispersant is a kind of in polypropylene wax, barium stearate, the calcium stearate preferably; The color of polypropylene Masterbatch is blue, black, and hyacinthine, orange-yellow etc.
2, above-mentioned raw materials is progressively added in the mixing agitator stir, 59～90 ℃ of whipping temps, mixing time 15-25 minute, melt extrude at 190～250 ℃ through single screw rod or double screw extruder then, be cut into particle, make master batch A;
3, master batch A drops into screw extruder after super-dry, melt extrudes at 190～260 ℃, forms fiber through spinning pack, forms silk tube B with up-coiler under 400～1000 meters/minute winding speed, uses for the hospital gauze braiding.
The production stage of second method is as follows:
1, get the raw materials ready according to following weight ratio:
Polypropylene chip or powder 30～35% barium sulfate 60～68%
Compatilizer 0.5～3% reinforcing agent 0.5～5%
Flexibilizer 0.1～2% antioxidant 0.1～1%
Wet master batch 0.1～2% dispersant 0.1～1% falls in polypropylene
Compatilizer a kind of in maleic anhydride (MAH), succinyl oxide, the EP rubbers preferably wherein; Reinforcing agent is ethylene-octene copolymer (POE); Flexibilizer is ethylene propylene diene rubber (EPDN) or acrylate rubber; The antioxidant model is a kind of in 1010,3114,330 preferably; Dispersant is a kind of in polypropylene wax, barium stearate, the calcium stearate preferably; The color of polypropylene Masterbatch is blue, black, and hyacinthine, orange-yellow etc.
2, above-mentioned raw materials is progressively added in the mixing agitator stir, 59～90 ℃ of whipping temps, mixing time 15-25 minute, melt extrude at 190～250 ℃ through single screw rod or double screw extruder then, be cut into particle, make master batch C;
3, master batch C is after super-dry, the also removal moisture drying of polypropylene Masterbatch of gross weight 0.5～5% will be accounted for, master batch C and Masterbatch are evenly mixed, drop into screw extruder, melt extrude at 190～260 ℃, form fiber through spinning pack, under 400～1000 meters/minute winding speed, form silk tube B, use for the hospital gauze braiding with up-coiler.
The production stage of the third method is as follows:
1, at first will cut into slices polypropylene, polypropylene cooling masterbatch, maleic anhydride, ethylene-octene copolymer, the ethylene propylene diene rubber of shape is ground into powder with pulverizer;
2, get the raw materials ready ratio and the production stage of above-mentioned powder, produce medical X-ray developing fiber silk tube according to first kind of production method.
The present invention compares with existing production technology, and following characteristics are arranged:
1, the present invention is carrier with the polypropylene, for polyvinyl chloride, human body is free from side effects, and no hemolytic reaction belongs to green material.
2, developing fiber of the present invention is that multifilament, filament number are less, smooth and soft, and braiding property is good, anti-high humidity sterilization, and washable folding is folded.
3, because the present invention has used reinforcing agent and flexibilizer, further improved TENSILE STRENGTH, elongation at break and the back processing characteristics of developing fiber, be suitable for extensive continuous and stable production.With the hospital gauze intensity height that its braiding forms, good toughness, development effect is obvious, wash resistant, folded, the anti-high humidity sterilization of folding and nontoxic, and serviceability is good.
