The invention relates to a processing technology of melt-spun antibacterial spandex filaments, which is characterized by comprising the following steps: firstly, cleaning a thermoplastic polyurethane slice, mixing the slice with substances including an antibacterial additive, drying, adding the mixture into a screw extruder, and melting and mixing; secondly, adding a cross-linking agent into the metering section of the extruder or after the extruder and before the extruder enters the mixer; thirdly, the melt spinning material is sprayed out by a spinneret plate, spun and wound for forming; finally, a finished product is prepared, and on the premise of solving the problem of composite spinning of various additives and polyurethane, functional spandex filaments with a broad-spectrum antibacterial effect are produced, the process is simple, the product quality is stable, the filaments can be used for producing medical elastic materials, sanitary clothes, high-grade fashion clothes and other fields, the prepared textile does not need to be subjected to additional antibacterial finishing, the production cost is greatly reduced, and the antibacterial performance is greatly improved.
Description
Technical field
The present invention relates to a kind of processing technology of spandex, particularly a kind of technology of producing antibiotic spandex filament with the melt-spun mode of production belongs to the chemical fibre production technical field.
Background technology
The production technology of spandex can be divided 4 kinds: dry-spinning, wet spinning, reaction are spun and melt-spun.No matter be to use which kind of spinning technique, the spandex fibre chemical property of being produced is identical basically, mostly is white, opaque extinction type long filament, and there is some difference according to the difference of production technology for shape of cross section.That the dry spinning spandex silk mostly is is round, ellipse and dumbbell-shaped section; Wet spinning and chemistry spin the spandex silk and are mainly thick leaf and irregular section, and vertically form irregular bonding point because welding (or bonding) takes place at it between each strand, form bonding multifilament bundled thus; Melt spun spandex is mainly the monofilament or the multifilament of circular cross-section.Dry-spinning is most widely used in the world at present spandex fiber method, and output is about 80% of world's spandex total output.Dry-spinning technology maturation, fiber quality of making and performance are all very good, but technical difficulty is bigger, need solvent recovery, and production cost is higher relatively.Wet spinning and reaction spinning process flow process complexity, the appliance arrangement investment cost is big, and spinning speed is lower, the production cost height, this method is eliminated gradually.Melt-spun is the new method of the manufacturing spandex that gets up of developed recently, has the advantage that dry-spinning and reaction are spun, and technological process is simple, equipment investment is low, production efficiency is high, spin speed and generally can reach 400～800m/min, and be easy to realize the thin dawnization of spandex, need not use solvent in process of production, be the most economic and the most friendly to environment spandex production technology.Utilization melt spun spandex technology, any production commercial city can produce spandex voluntarily, and color, additive and fibre diameter can be selected.
The process route that melt-spun is produced spandex has a small amount of enterprise to adopt at home, but generally produces conventional variety.Chinese patent CN1410605 discloses a kind of preparation method of melt spinning polyurethane fiber thin denier filament, adopts the mode of adding a kind of crosslinking agent in the production process to carry out making after the modification, but never obtains large-scale production practices checking, and product quality can't guarantee.
Through our retrieval, also do not have functional spandex silk to occur at present, as antibiotic, coloured or other classification.
Summary of the invention
The object of the present invention is to provide a kind of melt-spun processing technology with spandex filament of long acting antibiotic function.
The technical solution used in the present invention is: a kind of processing technology of melt-spun antibiotic spandex filament, it comprises the steps:
1, analog thermoplastic polyurethane section is mixed the back drying with the material that comprises antibacterial additives after cleaning, add in the screw extruder and carry out fusion, mixing;
2, at the metering section of extruder or after going out extruder, add a class crosslinking agent before entering blender;
3, the melt-spun material is through spinnerets ejection, spinning and coiling and molding;
Described main production flow process is: section cleaning → drying → extruder → blender → spinnerets and assembly → drawing-off → cool off → oil → reel.
Described thermoplastic polyurethane is by 4,4-methylene two phenylene diisocyanates and 1, the block polymers of polyurethane that the polycondensation of 4-butanediol is obtained.
Described crosslinking agent comprises polyether-type crosslinking agent, polyester-type crosslinking agent and polyether-polyester mixed type crosslinking agent.
Described polyether-type crosslinking agent is by polyether polyol, isocyanate reaction and get;
Described polyester-type crosslinking agent is by poly-vinegar polyalcohol, isocyanate reaction and get;
Described polyether-polyester mixed type crosslinking agent is the polyols blend that is made of polyether polyol and polyester polyol, isocyanate reaction and get.
It is 60-600m that described antibacterial additives adopts specific area
2The silica of/g, or particle diameter is the silica of 80-200nm, with excessive H
2O
2Perhaps D/W reaction, the nanometer powder that product makes through comprising filtration, washing, drying, screening process.
The method of the invention is under the prerequisite that has solved multiclass additive and polyurethane composite spinning, produced functional spandex filament with broad-spectrum antimicrobial effect, such long filament can be used for producing medical elastic material, hygiene garments, top-grade fashion and other field, made textiles no longer needs to carry out in addition antibiotic finish, production cost reduces greatly, and anti-microbial property improves greatly.This method technology is simple, under the condition of having formulated the reasonable process parameter, and product with stable quality.
Its advantage is mainly reflected in:
1, the productivity effect height, input is low, operating cost is low;
2, owing to do not need solvent in the technology, it is a kind of environment-friendly type technique;
3, produce flexibly, adopt different additive and raw material, can process the fiber of different elongations, intensity, fineness;
4, product has higher chlorine and floats and hydrolytic stability;
5, produce simply, it is synthetic not need to purify, and is simple slice spinning.
The specific embodiment
The thermoplastic polyurethane section mixes back dry after cleaning with antibacterial additives, dried material adds in the screw extruder, fusion, mixing, at the metering section of extruder or after going out extruder and add quantitative crosslinking agent before entering blender, the melt-spun material sprays through spinnerets, spun filament is stretched, cools off, oils, reels, promptly get melt-spun antibiotic spandex filament.
The described method of present embodiment adopts 48 first melts of German FOURNE polymerization technique company to spin spandex equipment, equipment adopts electrical heating spinning (300 ℃ of maximum temperatures), raw material are TPU section and additive, every suit is equipped with 4 Spinning pumpss, 24 cover filament spinning component and 4 up-coilers, its maximum winding speed can reach 1200m/min, product fiber number 17-240dtex.Antibiotic spandex filament product quality such as tensile strength, extension at break, modulus, recovery characteristic and the uniformity that this method is produced all can be suitable with mill run, its anti-microbial property detects through authoritative institution, the bacterium that surpasses more than 90% is all had inhibitory action, and effect keeps for a long time.
