日前,安庆石化承担的“细旦腈纶纤维生产与试纺服务”项目,通过专家组结题验收。从2010年起,安庆石化开始与东华大学联合对细旦纤维成型工艺进行探索。他们确定了细旦腈纶的纺丝工艺,包括负拉伸率、牵伸倍数、凝固条件及致密化条件等;研究设计细旦腈纶纤维纺丝专用喷丝板,增加了孔的密度,设计了合理的孔分布;改进在线牵伸设备,使装置具备规模化生产能力。在细旦腈纶纤维小试的基础上,他们在纺丝生产线对应的二次滤机及纺丝烛型滤器上使用新型精
Recently, Anqing Petrochemical commitment “Fine denier acrylic fiber production and test spinning service ” project, through the expert group check acceptance. Since 2010, Anqing Petrochemical Co., Ltd. and Donghua University have started to explore fine fiber forming process. They identified the fine acrylic fiber spinning process, including negative tensile elongation, draw ratio, solidification conditions and densification conditions; research and design fine denier acrylic fiber spinning special spinneret, increasing the density of the hole, designed Reasonable hole distribution; improve on-line drafting equipment, the device has large-scale production capacity. In the fine denier acrylic fiber based on the small test, they are in the spinning production line corresponding to the second filter and spinning candle filter using the new type of fine
