Abstract
The invention discloses a kind of processing technology of long acting antibiotic spandex filament, comprise the following steps：A, thermoplastic polyurethane is cut into slices after cleaned drying to mix to add in screw extruder with antiseptic and is melted, be kneaded；B, the metering section of extruder or after extruder, into adding crosslinking agent before blender；C, melt-spun material sprayed through spinneret, spinning and coiling and molding, finally obtain finished product.The technological process of production is：Section cleaning-drying-extrusion-mixing-spinneret-drawing-off-cool down-oil-is wound.Antiseptic is silver powder, and silver powder is nano-scale silver powder.The beneficial effects of the invention are as follows：Production is simple, production efficiency is high, input is low, product anti-microbial property is preferable, and Durability of antimicrobial effect is stronger, steady quality, easy to spread.
Description
Technical field
The present invention relates to chemical fibre processing technique field, especially a kind of processing technology of long acting antibiotic spandex filament.
Background technology
It is wherein relatively common one kind that chemical fibre, which is divided into a variety of spandexs, and the production technology of spandex can be divided into 4 kinds：Dry-spinning,
Wet spinning, reaction is spun and melt-spun.Whether which kind of spinning technique is used, the chemical fibre property produced substantially completely phase
Together, mostly white long filament, there is some difference according to the difference of production technology for shape of cross section.Dry spinning spandex long filament is mostly to justify
Type, ellipse level dumbbell shape cross section；Wet spinning and chemistry spin spandex filament be mainly thick blade profile and irregular section not simultaneously
And hesitated between each strand and welding occurs and is longitudinally formed irregular adhesive spots at it, it is consequently formed bonding multifilament bundled；Melt-spun
Spandex is mainly the monofilament or multifilament in round section.Dry-spinning is current spandex fiber method most widely used in the world, yield
About the 80% of world's spandex total output.Dry spinning process technology maturation, manufactured fiber quality and performance are all very excellent, but technology
Difficulty is larger, needs solvent recovery, and production cost is of a relatively high.Wet spinning and reaction spinning process are complicated, and appliance arrangement investment cost is big,
Spinning speed is relatively low, and production cost is high, and the method has been eliminated substantially, and melt-spun is the new side for the manufacture spandex that developed recently gets up
Method, there is the advantages of dry-spinning and reaction are spun, and technological process is simple, equipment investment is low, production efficiency is high, and it is general reachable to spin speed
It is the most economic and the most beneficial to environment spandex production in process of production without using solvent to 400-800m/min
Technology.With melt spun spandex technology, any manufacturer can voluntarily produce spandex, and color, additive and fibre diameter can appoint
Meaning selection.
Spandex at present on the market is relatively conventional, and the species of present bacterium is more and more, and common spandex does not possess antibacterial
Function, it is impossible to meet the needs of modern people, therefore be badly in need of a kind of improved technology to solve above-mentioned technological deficiency.
The content of the invention
The invention provides a kind of processing technology of long acting antibiotic spandex filament.
The present invention is directed to the technical scheme that above-mentioned technological deficiency is proposed：
A kind of processing technology of long acting antibiotic spandex filament, comprises the following steps：A, thermoplastic polyurethane section through clear
Wash after drying to mix to add in screw extruder with antiseptic and melted, be kneaded；B, extruder metering section or extruding
After machine, into adding crosslinking agent before blender；C, melt-spun material sprayed through spinneret, spinning and coiling and molding, finally obtain into
Product.
The technological process of production is：Section cleaning-drying-extrusion-mixing-spinneret-drawing-off-cool down-oil-is rolled up
Around.
The antiseptic is silver powder, and the silver powder is nano-scale silver powder.
The beneficial effects of the invention are as follows：Production is simple, production efficiency is high, input is low, product anti-microbial property is preferable, and antibacterial is held
Long property is stronger, and steady quality is easy to spread.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment
It is only used for explaining the present invention, does not form the restriction to protection scope of the present invention.
A kind of processing technology of long acting antibiotic spandex filament, comprises the following steps：A, thermoplastic polyurethane section through clear
Wash after drying to mix to add in screw extruder with antiseptic and melted, be kneaded；B, extruder metering section or extruding
After machine, into adding crosslinking agent before blender；C, melt-spun material sprayed through spinneret, spinning and coiling and molding, finally obtain into
Product.
The technological process of production is：Section cleaning-drying-extrusion-mixing-spinneret-drawing-off-cool down-oil-is rolled up
Around.
Antiseptic is silver powder, and silver powder is nano-scale silver powder.
The beneficial effects of the invention are as follows：Production is simple, production efficiency is high, input is low, product anti-microbial property is preferable, and antibacterial is held
Long property is stronger, and steady quality is easy to spread.
Described above is not the limitation for making any other form to the present invention, and the technical spirit according to the present invention is made
Any modification or equivalent variations, still fall within scope of the present invention.
