The invention relates to a chemical fiber industrial filament, a manufacturing method thereof and a safety airbag, and the manufacturing method of the chemical fiber industrial filament comprises the following steps: carrying out pre-crystallization treatment on a polyester chip with preset viscosity, and then carrying out solid phase polymerization treatment to obtain a polymerization tackified chip; the polymerization tackifying slices are placed in a screw extruder to be subjected to melting treatment, and spinning melt is obtained; the spinning melt is filtered through a filter screen in a spinning assembly; and enabling the filtered spinning melt to pass through a spinneret plate in a preset spinning assembly so as to form a chemical fiber filament continuum formed by compounding a plurality of fiber bundles. The spinneret plate comprises a first through hole area and a second through hole area which are provided with spinneret holes, and a partition part used for separating the first through hole area and the second through hole area, and the density of the spinneret holes becomes dense from outside to inside. Compared with the prior art, the filament number and the broken filament amount of the chemical fiber industrial filament can be further reduced, and meanwhile good mechanical performance is kept.

    本发明涉及一种化纤工业长丝及其制造方法以及安全气囊,该化纤工业长丝的制造方法包括:将预设粘度的聚酯切片进行预结晶处理,然后进行固相聚合处理,得到聚合增粘切片;将聚合增粘切片置入螺杆挤压机中熔融处理,得到纺丝熔体;将纺丝熔体通过纺丝组件中的过滤网进行过滤处理;将过滤后的纺丝熔体通过预设纺丝组件中的喷丝板,以形成多根纤维束复合而成的化纤长丝连续体。喷丝板包括:具有喷丝孔的第一通孔区和第二通孔区,以及用于分隔第一通孔区和第二通孔区的隔断部,并且,喷丝孔的密度由外向内,由疏变密。与现有技术相比,本申请可以在进一步降低化纤工业长丝的单丝纤度和毛丝量的同时,保持良好的力学性能。
