1.56 dtex阳离子可染中空涤纶短纤维的纺丝工艺
China Synthetic Fiber Industry(2011)
Abstract
采用阳离子可染聚酯切片为原料,熔融纺丝制得1.56 dtex阳离子可染中空涤纶短纤维,探讨了纺丝工艺参数对生产及纤维性能的影响。结果表明:控制干切片的含水率小于30μg/g,组件初始压力10.5~12.0MPa,纺丝温度278~283℃,单孔吐出量0.39~0.45g/min,纺丝速度1100~1250m/min,环吹风速度0.9~1.1m/s、温度24~27℃,纺丝过程顺利稳定,中空成形良好,纤维物理指标优良,其断裂强度为3.50cN/dtex,断裂伸长率为24%,中空度为15%。
