Description
Technical field
The present invention relates to ultra high molecular weight polyethylene fibers, the in particular to life of bacterial type ultra high molecular weight polyethylene fiber
It produces.
Background technique
Ultra-high molecular weight polyethylene (UHMWPE) fiber has the characteristics that high-strength, Gao Mo, high thermal conductivity, has in many fields
There is irreplaceability.Producing a kind of UHMWPE fiber with bacteria resistance function has initiative, can enrich UHMWPE fiber
Performance and function expand UHMWPE fiber in the application in the fields such as civilian fabric, medical equipment.
UHMWPE fiber have low surface can and surface tension, high crystallinity, extremely smooth surface, and it is common
Inorganic, organic bacteriostatic agent is difficult effectively to combine, this to handle UHMWPE by padding, coating the post processing modes such as bacteriostatic agent
The fungistatic effect of fiber and fabric is poor, timeliness is short.If directly adding bacteriostatic agent in process of production, because UHMWPE fiber produces
It needs by high-temperature digestion, spinning (wet spinning is greater than 220 degree, and dry spinning is greater than 142 degree) and high temperature hot gas spring (drawing-off
Temperature 120-155 degree) etc. processes, a variety of bacteriostatic agents at high temperature easily occur chemical reaction and cause to fail；UHMWPE fiber
Production need to by hydrolysis and various solvent extractions washing (common extractant include: dimethylbenzene, agent for carbon hydrogen detergent, methylene chloride,
Tetrachloro-ethylene, trichorotrifluoroethane etc.) process, cause small molecule bacteriostatic agent to be largely lost in process of production, cause antibacterial
Agent content reduces, and fungistatic effect is deteriorated.In addition, UHMWPE fiber has low surface energy and surface tension, high crystallinity, i.e.,
Make that UHMWPE precursor is added in small molecule bacteriostatic agent by way of addition before spinning, subsequent production small molecular bacteriostatic agent is also
Can to fiber surface migration and it is rapidly losing.
CN106589582A discloses a kind of activeness and quietness antibacterial polypropylene material and its production method, uses nano oxygen
Change zinc or titanium dioxide as inorganic antiseptic, then by polypropylene, ultra-high molecular weight polyethylene master batch, inorganic antiseptic, connect
Branch polypropylene and other auxiliary agents squeeze out to obtain activeness and quietness antibacterial polypropylene material by double screw extruder melt blending, however
By method, it is applied in the production of ultra-high molecular weight polyethylene (UHMWPE) fiber, and antibiotic rate substantially reduces, and to breaking strength
And initial modulus produces negative effect, in addition TiO2 only just has antibacterial effect by ultraviolet excitation
Fruit does not have bacteriostasis under other conditions.CN105175863A discloses a kind of ultra-high molecular weight polyethylene internal coat pipeline,
Using the raw material proportioning of following parts by weight: poly- four of the low molecular weight within 85~95 parts, 10 microns of ultra-high molecular weight polyethylene
1.5~2 parts of vinyl fluoride micro mist, 1~2 part of zinc stearate lubricant, 0.1~0.5 part of antioxidant, 1~3 part of nano antibacterial agent, glass
1~7 part of glass microballon, 0.1~3 part of mica, 0.1~2 part of carbon fiber, 0.1~0.5 part of vinyltrimethoxysilane coupling agent,
The wherein antibacterial agent of the nano antibacterial agent to be a kind of containing metallic silver or metallic gold be main antimicrobial component；
CN107151403A discloses a kind of antibacterial water supply line, the raw material including following parts by weight: 20~50 parts of Corvic, chlorine

Agent is nano silver ion antibiotic agent, is added directly into antibacterial agent in preparation process and carries out extrusion operation；Above-mentioned acquisition material
Antibiotic rate can not obtain Utopian effect, limit it in the application of field of medicaments material, be suitable only for anti-corrosion pipe
Industrial circles such as road, and since its inorganic antibacterial agent molecule is small, the migration velocity of inorganic particulate is big, be easy to lose from material into
One step reduces its antibiotic rate.
By being analyzed above it is found that most of bacteriostatic agents are not suitable for the production of UHMWPE fiber substantially；And bacteriostatic agent pair
Without contribution, the performance that a large amount of addition bacteriostatic agents will lead to UHMWPE fiber is remarkably decreased the intensity of UHMWPE fiber；And bacteriostatic agent
Or the large-size particle generated by reunion but will become the defect sturcture of fiber, so that fibre property declines more rapid,
