POY135dtex/288f环吹风生产工艺分析

Production Process Analysis of POY135dtex/288f Ring Blower

随着国内聚酯(PET)长丝制造商规模的不断扩大,市场日益饱和,常规纺丝已经远远无法保证企业的强劲竞争力。唯有持续地研发高品质且富有附加值的新型品种,企业才不会被市场所淘汰。其间充分利用超细旦多孔丝的优良毛细效应和特有的弯钢性,经后加工制造出桃皮绒、防水透气织物和仿真丝仿麻等。这种纤维制成的织物具有诸多应用优势,因此熔体直纺135dtex/288f产品的研制和开发对于企业进一步开拓市场、拓宽产品组合结构来说有着非常重要的作用。多次试验研究结果显示,采用熔体直纺和环吹式冷却、纺丝温度290~300℃、无风区高度55~75 mm,风压10~20 Pa、油架高度500~600 mm等工艺条件时,生产保持稳定,产品能够满足客户的要求。

With the continuous expansion of domestic polyester(PET)filament manufacturers,the market is becom⁃ing increasingly saturated,conventional spinning has been far from guaranteeing the strong competitiveness of enter⁃prises.Only by continuously researching and developing new types of high-quality and value-added products can companies not be eliminated by the market.In the meantime,it makes full use of the excellent capillary effect and unique bending properties of ultra-fine denier porous yarn,and after post-processing,peach skin,waterproof and breathable fabric and artificial silk and linen are produced.The fabric made of this fiber has many application advan⁃tages,so the research and development of the melt direct spinning 135dtex/288f product plays a very important role for the company to further expand the market and broaden the product portfolio structure.The results of many experi⁃ments have shown that under the process conditions of adopting melt direct spinning and ring blowing cooling,spin⁃ning temperature 290~300℃,windless zone height 55~75 mm,wind pressure 10~20 Pa,oil rack height 500~600 mm,etc.,the production remains stable,and the products can meet customer requirements.
