The technique that the present invention produces 6 elastic filament of cationic dye capable of dyeing polyamide fibre, it is characterised in that：Cationic dye capable of dyeing brocade
The production craft step of 6 preoriented yarn of synthetic fibre is as follows：
1）Slice that is stored in feed bin and providing needed for production is sent to screw extruder；
2）Screw extruder will be sliced through feed zone, compression section, metering section heated, melted, measured and generated it is predetermined
Pressure is squeezed out from the head of screw rod；
3）The melt of extrusion enters melt metering pump, melt metering pump then accurate measurement, continuous conveying high polymer molten,
And the scheduled pressure of institute is generated, to ensure that spinning melt overcomes the resistance of filament spinning component, sprays from spinneret, formed in air
As-spun fibre；
4）The melt that filament spinning component sends melt metering pump, it is after mixing, micro- from spinneret through filtering off removal of impurities matter
Filament item is equably sprayed into hole, then being quickly cooled down through side-blown air cooling system and slow cooling form the crystallization good fibre of orthodromic
Dimension；
5）Fiber after molding carries out the operation that oils by oil feeding system, is carried out to strand to oil feeding system homogeneous constant
Oil reduces the frictional force of strand and silk road, increases the coherent of silk, eliminates electrostatic, promotes spinning efficiency, it is ensured that subsequent handling
Processing efficiency；
6）Fiber after oiling imports two draw-off godets, strand stretch by the friction speeds of two draw-off godets and
Thermal finalization makes silk reach quality requirement to change the internal structure of silk, enters pre-network device, pre-network device thereafter
Strand tow under relatively low gas pressure is set to wind mutually, oil content evenly, increases the coherent of silk；
7）Strand is set uniformly to be coiled into package regularly eventually by winding operation through pre-network device treated fiber,
Form 6 preoriented yarn of cationic dye capable of dyeing polyamide fibre.
Further, 6 elastic force of cationic dye capable of dyeing polyamide fibre is made in above-mentioned 6 preoriented yarn of cationic dye capable of dyeing polyamide fibre
The preparation method of silk passes through following step successively：
1）6 preoriented yarn of cationic dye capable of dyeing polyamide fibre passes through the transmission of wire leading pipe, and by after the cutting away of yarn cutter, by one
Roller is drawn, and holds strand together by apron and roller, strand is made to be stretched, it is desirable that protect surface of roller not by
Suction gun, billhook etc. are damaged, and apron wants intact, without groove mark, and seamless with surface of roller pressing, otherwise apron easily goes out without silk is twined
Existing deadlock silk etc.,
2）Only twisting by twist arrester, strand is fixed at the top of hot tank, playing prevents the strand twist from passing after roller
The effect passed,
3）Strand is heated through hot tank after only twisting and cooling of the coldplate to fiber coiled structure after false twisting
It is fixed,
4）Rubbing through scroll tube after cooling, the effect of scroll tube are to generate mechanical distortion stress, so as to deformation processing, it
It is the core of elasticizer；
5）Then the traction of the tension detection and the second roller of warp tension device：Spinline tension fluctuation monitoring in detection line,
Prevent abnormal tension silk generation of weaving；
6）Then the purging through network nozzle increases strand to form network-like node with compressed air purging to strand
Coherent；
7）Then the spy silk of traction and yarn probe through third roller, when silk breaks end, yarn probe can be anti-by information in time
It is fed to yarn cutter, yarn cutter cuts off silk, and roller in the entire the Silk Road of silk no longer for, there is no strand process, preventing roller and twining
Silk, apron wheel twine silk, to protect equipment；
8）Then pass through oil tanker oiling treatment, mainly finish appropriate is added to elastic filament, to improve the boundling of fiber
Property, increase the flatness of fiber, improves the antistatic property of fiber, the woven requirement in road after adaptation；
9）It finally winds, allows strand is uniformly regular to be wrapped into 6 elastic filament of cationic dye capable of dyeing polyamide fibre.
Further, the control of 6 preoriented yarn main technologic parameters of above-mentioned cationic dye capable of dyeing polyamide fibre is as follows：
Biphenyl temperature：250-288 DEG C, melt temperature：253-275 DEG C, spin pressure：110-120kgf/ cm2, G.P rotating speeds：
12.3-25.4rpm, O.P rotating speed：11.5-18.9rpm, side-blown wind speed：0.35-0.6m/s, draw ratio DR：1.03-1.05 spinning
Speed：4300-4600m/min.
Further, the control of 6 elastic filament main technologic parameters of above-mentioned cationic dye capable of dyeing polyamide fibre is as follows：
Ingot group：1-4-1 ~ 1-8-1, heater temperature：170-210 DEG C, draw ratio DR:1.25-1.30, D/Y ratio：1.5-2.5
