Field.
Invention content
Goal of the invention：Purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of product intensity height, does
Percent thermal shrinkage is low, the production method of 12 spinning fine denier high intensity low shrinkage type polyester industrial yarns of high-quality of excellent heat resistance.
Technical solution：In order to solve the above-mentioned technical problem, it is low to spin fine denier high intensity for a kind of high-quality 12 of the present invention
The production method of miniature polyester industrial yarn, it includes extrusion molten, metering, Slow cooling, side-blown air cooling, first of spinning collection
Beam oils, stretch before second oils, six two pairs of rollers drawing and settings, knit a net network knot, coiling and molding；
The extrusion molten：Using a diameter of 90-105mm screw extruders, screw rod heating zone is six areas, an area temperature 315-
300 DEG C, two 310-295 DEG C of areas, three 305-295 DEG C of areas, 4th area cool down district by district to 295-290 DEG C of 6th area；
The metering：Using 4.5-6.0cc/rpm metering pumps, 10-25 revs/min of rotating speed；
The Slow cooling：Melt quantitative is sent to 12 single filament spinning components by metering pump, is sprayed through diameter 80-90mm spinneret holes
Go out, using mobile annealer, 300-320 DEG C of temperature declines in shovel board；
The side-blown air cooling：It by the tow of slow cooling, is cooled down by the cold wind that quenching air window is uniformly blown out, completes solidification
Molding, 20-23 DEG C of temperature, wind speed 0.4-0.7m/s, relative humidity 75-90%；
First of spinning boundling oils：After tow cooling, by second floor spinning shaft lower part, using on oil nozzle boundling
Oil, finish are this GXM-100 of pine, and oil applying rate is controlled in 0.3-0.5%；
Second oils before the stretching：Before stretching starts, being oiled using oil nozzle second, finish is pine this GXM-100, one
Two total oil applying rate 0.6-0.9% of road；
The six two pairs of rollers drawing and setting：The tow to oil through twice carries out drawing and setting, first pair of heat roller temperature by six two pairs of rollers
75-85 DEG C, second pair of 90-95 DEG C of hot-rolling, third is to 120-130 DEG C of hot-rolling, fourth, fifth pair of 230-245 DEG C of hot-rolling, the 6th pair of heat
160-190 DEG C of roller is stretched using two-stage and is bounced back with two-stage, and total draw ratio 5.5-6.0, always bounce back 7-9%, tensile speed 2800-
3100m/min, winding speed 2700-3000m/min；
The network knot that knits a net：After the completion of drawing and setting, Switzerland Heberlein respective model nozzles, network pressure 2.5- are used
3.0 bar；
The coiling and molding：Using double six winder windings around precise forming.
Hot-rolling diameter 220mm in the six two pairs of rollers drawing and setting.
Double six 2, up- coiler, that is, band position 12 up- coilers.
Advantageous effect：Compared with prior art, the present invention its remarkable advantage is：The fiber number model of the finished product fine denier filament of the present invention
It encloses：- 250 denier of 100 denier, hole count 36-72；Fine denier filament is 12 straight spinning low-shrinkage high-strength polyester industrial yarns, intensity >=7.1cn/
Dt, dry-hot shrinkage 2.5%-3.5%, (190 degree, 0.01cn/dtex) are better than conventional intensity 6.4cn/dtex products, xeothermic receipts
Shrinkage is lower than conventional products 5%, excellent heat resistance；Using diameter 80-90mm spinnerets,（Conventional 165-190mm）, Melt residence
Time reduces more than half, 12 single components, 4.5-6.0cc/rpm metering pumps, 10-25 revs/min of rotating speed, ensures fiber number
Uniformly；Using a diameter of 90-105mm screw extruders, 2, band position 12 up- coiler, mating melt distribution pipe ensures molten
Body total residence time is less than 5 minutes, reduces melt degradation, improves finished silk intensity；Extrusion molten is using the heating gradually to cool down
Technique ensures slice melting uniformly and melt outlet temperature is relatively low, is convenient for side-blown air cooling；Using removable novel annealer,
Decline in shovel board, reduce labor intensity and difficulty, ensure shovel board quality, reduces lousiness；It is different from traditional winding to oil, adopt
Yarn unevenness is effectively reduced, is reduced simultaneously under the premise of being ensured to oil uniformity with the mode of first of spin finishing
Spinning tension reduces the generation of lousiness, and second, which oils, is placed on winding, ensures the uniformity to oil；It is fixed using six pairs of roller stretchings
Type mode increases the stretcher strain residence time wherein the first two pairs of rollers just use hot-rolling, tensile stress is reduced, to effectively reduce
Lousiness；Using double six winder windings around precise forming, compared with 4-8 are spun, under the premise of ensureing quality, production is effectively increased
Can, cost is reduced, market competition advantage is apparent.
