Description
Technical field
The present invention relates to the preparation method that a kind of toughness reinforcing anlistatig high-performance strengthens POLYAMIDE YARNS, belong to chemical fiber field.
Background technology
Polyamide fibre is the trade name of polyamide fiber, polyamide fiber is commonly called as nylon (Nylon), English name Polyamide(is called for short PA), density 1.15g/cm3, be on molecular backbone containing recurring amide radical group-[NHCO]-thermoplastic resin general name, comprise aliphatic PA, fat-aromatic series PA and aromatic series PA.Wherein aliphatic PA is wide in variety, and output is large, and be widely used, its name is determined by the carbon number that synthon is concrete.
Polyamide is mainly used in synthetic fiber, its most outstanding advantage be ABRASION RESISTANCE higher than other all fibres, higher than cotton ABRASION RESISTANCE 10 times, higher than wool 20 times, in BLENDED FABRIC, enter some polyamide fibers a little, can greatly improve its ABRASION RESISTANCE; When being stretched to 3-6%, elastic recovery rate can reach 100%; Up to ten thousand foldings can be stood scratch and do not rupture.The strength ratio cotton height 1-2 of polyamide fiber doubly, than wool height 4-5 doubly, is 3 times of viscose.But the heat resistance of polyamide fiber and light resistance poor, retentivity is not good yet, the clothes made not as terylene well-pressed.In addition, the shortcoming of hygroscopicity and dyeability difference is all there is for the nylon-66 of wearing clothes and polyamide fibre-6, develop the new varieties of polyamide fiber for this reason---the novel polyamide fiber of poly-β-alanine and polyamide fibre-4, have that light weight, wrinkle resistance are excellent, the feature such as good permeability and good durability, dyeability and HEAT SETTING, be therefore considered to rising.
Because polyamide has nontoxic, light weight, excellent mechanical strength, ABRASION RESISTANCE and corrosion resistance preferably, therefore be widely used in replacing the metals such as copper to manufacture bearing, gear, pump leaf and other parts in the industry such as machinery, chemical industry, instrument, automobile, be applicable to make wear part, drive mechanism part, household appliance components, automobile making part, screw mandrel prevents machine components, chemical machinery part, chemical industry equipment.As turbine, gear, bearing, impeller, crank, instrument board, driving shaft, valve, blade, screw mandrel, high pressure packing ring, screw, nut, sealing ring, shuttle, cover letter, axle sleeve connector etc.Molten polyamide has very high intensity after being spun into silk, mainly makees synthetic fiber and can be used as medical suture.On civilian, can blending or be purely spun into various medical treatment and knitwear.Chinlon filament is used for knitting and silk textile industry, as knitted the polyamide fibre socks of the various wear-resisting explanation such as monofilament hose, elastic force silk stocking, polyamide fibre gauze kerchief, mosquito net, polyamide fibre lace, elastic force polyamide fibre coat, the silk product of various polyamide fibre silk fabric or intertexture.Polyamide staple fibre is mostly used for the wool type product blending with wool or other chemical fibre, makes the various wear-resisting dress material worn long.Industrially polyamide fibre is used for manufacturing cord fabric thread, industrial cloth, hawser, conveyer belt, tent, fishing net etc. in a large number.Main as parachute and other army fabrics in national defence.
Existing high-performance polyamide fibre, can only have in enhancing, the performance such as fire-retardant, weather-proof wherein one or both, lack the high-performance polyamide fibre simultaneously possessing multiple performance.
Summary of the invention

Toughness reinforcing anlistatig high-performance of the present invention strengthens the preparation method of POLYAMIDE YARNS, comprises the following steps:
1) raw material: PA6 section 65-75 weight portion, nano silicon 20-30 weight portion, maleic anhydride melt grafting EPDM 4-6 weight portion, interior mixed type antistatic additive 4-6 weight portion and auxiliary agent 2-5 weight portion is prepared according to following proportioning, described auxiliary agent comprises coupling agent, anti-oxidant auxiliary agent and lubricant, the weight ratio of three is 1:1:1, adds in high-speed mixer and mixes;
2) drying process is carried out to raw material;
3) spin fluid is prepared: utilize master batch to annotate pump and accurately add each raw material, mixed melting;
4) spinning: above-mentioned spin fluid is quantitatively pressed into filament spinning component through measuring pump, is sprayed by spinnerets, forms tow in spinning window;
5) aft-loaded airfoil: the fiber made is carried out successively draw-teisting, sizing, balance, dyeing grades and test package operation.
Preferably,
Described raw material comprises following ingredients, and: PA6 cuts into slices 70 weight portions, nano silicon 25 weight portion, maleic anhydride melt grafting EPDM 5 weight portion, interior mixed type antistatic additive 5 weight portion, coupling agent 1.5 weight portion, anti-oxidant auxiliary agent 1.5 weight portion and lubricant 1.5 weight portion.
