The quality of melting is not only related to the efficiency of production, and and physical index intensity, elongation, bar dry etc. closely related, directly have influence on rear road client's service efficiency and fabric quality.Melt pressure control adopts PID automatically to regulate, and should ensure that measuring pump feed ensures not feed back again, and pressure set points is most important.
(3), melt distributes:
Melt is under biphenyl jacket heat-preservation system, the holding temperature of biphenyl heat-insulation system is 247 DEG C～270 DEG C, biphenyl heat-insulation system adopts diphenyl boiler heating biphenyl to produce biphenyl steam, biphenyl steam pressure is 0.5～1.0kg, biphenyl steam adopts self-circulation mode to carry out heating and thermal insulation to melt pipe, melt pipe by the even constant temperature of melt be delivered to measuring pump, the time of delivery of melt in melt pipe is 6 minutes;
The length relation of melt pipe is to the time of staying of the pipeline of melt, overlong time is easily oxidized, production efficiency variation, suitable melt pipe is selected most important, but the height of biphenyl temperature can accelerate or delay the mobility of melt to a certain extent, thereby affect the time of staying of melt at pipeline.
(4), metering:
According to specification requirement, the optional specification of measuring pump has 0.9CC/r, 1.2CC/r, 1.6CC/r, 1.8CC/r, 2.4CC/r, and measuring pump revolution is 10～30 to turn;
According to specification requirement, employing one is entered ten and is gone out measuring pump setup parameter.
(5), spin mouth:
According to specification requirement, select spinnerets, the hole diameter of spinneret size is 0.1～0.4mm, spinnerets draw ratio is 2～3.5, spinning mouth initial pressure is 100kpa～200kpa, spinning speed and spin between mouth jet velocity and form a draw ratio, and draw ratio is 100～250; Spinning speed is 4500～5000m/min; After stretching, form silk;
According to specification requirement, select suitable spinnerets, spinnerets pass is arranged and is divided into circumference and rectangle, spin mouth plays and forms a connecting link in whole spinning technique process, vital effect, irrational draw ratio and draw ratio easily cause extending uniformity to be reduced, and too small or excessive the hole diameter of spinneret very easily produces lousiness, filament.
(6), monomer suction:
Adopt water stream injection pump to produce self-suction, can regulate suction by spraying water yield adjusting, the wind speed that water stream injection pump suction produces is 5m/s～15m/s;
Melt produces a large amount of monomers in cooling procedure, these lower-molecular substances, spinning is formed to harm, need to use monomer suction system that monomer is drained only, suction is too small cannot drain only the monomer that melt is separated out, and remains in spinnerets surface, and the shovel board cycle shortens, easily produce lousiness, head silk, affect production efficiency; The excessive silk that easily makes of suction is beated, the dry uniformity of bar of impact silk.
(7), cooling:
After section melting, spinning the interval in-draw processing of 10CM under mouth, after stretching, need to carry out cooling and shaping, coolingly regulate by oily frame height, cooling wind speed, chilling temperature, be 700MM～1400MM according to product specification oil frame height, cooling wind speed is 0.3M/S～0.65M/S, and chilling temperature is 16.5 DEG C～18.5 DEG C;
The cooling irregular bar that easily causes is dry bigger than normal, is made into cloth cover out-of-flatness after cloth.Cooling too fast or cross easily to cause slowly and oil irregularly, rear road warping easily produces lousiness, fracture of wire.Cooling is most important link in whole spinning process, and cooling quality directly affects the dry uniformity of elongation, bar of silk, the directly quality of impact silk.Tension force in cooling procedure on oil nozzle is as far as possible little, and this is adjusted by oily frame height and lateral blowing wind speed.Fine-denier porous tension force is in 9 grams.
(8), oil:

Employing single track oils, and selects oil nozzle, the finish of low-friction coefficient can effectively reduce the tension force on oil nozzle.Too low oil concentration does not reach the film strength needing, and easily on Si road, produces broken silk, and the too high oil concentration uniformity that can make to oil reduces.
(9), pre-network:
After silk oils, improve by the pre-network uniformity that makes to oil, pre-network pressure is 0.5kpa～1.5kpa;
Pre-network Main Function is the purge by air, and finish is evenly adsorbed on tow, and too low network pressure uniformity reduces, and too high network pressure makes finish loss too many.
(10), drafting forming:
