2）Will be through step 1）Obtained island textured filament feeds two rollers together with high convergency FDY silks, after two rollers, wherein island textured filament enters shaping heat box heat-shaping, high convergency FDY silks lead to shaping heat box bottom by an aluminum pipe, then enter network nozzle in the lump with the island textured filament after heat-shaping, after being bonded by network jet, into oil groove, and oiled by oil groove roller, then be sent into coiler device after three rollers and be wound shaping processing, that is, this high convergency type sea island filament is made；
Main technologic parameters are：
The specification of fabric of island-in-sea type POY silks is 130-250D, the specification of high convergency FDY silks is 20-90D, the heating-up temperature of deformation hot box is 165-180 DEG C, the heating-up temperature of shaping heat box is 150-165 DEG C, the speed of zero roller is 400-600m/min, the speed of one roller is 225-340m/min, the speed of two rollers is 400-600m/min, the speed of three rollers is 400-600m/min, the rotating speed of oil groove roller is 4-6r/min, the rotating speed of scroll tube is 4000-8000r/min, and pressure is 2.5-4.0kg/cm at network nozzle2。
A kind of high convergency type sea island filament, the specification of the high convergency type sea island filament is 100-250D.
The technical indicator that the high convergency type sea island filament meets is：Fracture strength >=3.20cN/dtex；The fracture strength coefficient of variation≤10.00%；Elongation at break 16.00% ~ 26.00%；The extension at break degree coefficient of variation≤10.00%；Boiling water shrinkage 22.4 ~ 23.6%, dye uniformity >=4 grade.
Compared with prior art, beneficial effect is the present invention：
By using fabric of island-in-sea type POY silks and high convergency FDY silks as raw material, so that this sea island filament is on the basis of the original feature of sea island filament is kept, improve its fracture strength, it is not easy to break in the sanding processing of Shi Qihou roads, while there is the highly shrinkable of high convergency FDY silks, strand shrinks after high-temperature heating, becomes apparent from its curling, wool-like effect is more preferable after road sanding processing after, and feel is also more soft；
After reinforcing network point, remove the processes such as rear road starching desizing from, saved cost, reduce pollution, protect environment；
The fabric obtained by the high convergency type island silk weaving, because diminishing after contraction through gap between silk and tram, density increase, cloth cover more has waxy.
