摘要:
以尼龙66半消光切片为原料,采用熔融纺丝工艺制备70 dtex/34 f半消光全拉伸丝,系统研究了纺丝温度、纺丝速度及热辊温度对纤维性能的影响。结果表明:纺丝温度290 ℃ 时,结晶度达22.69%,断裂强度为3.99 cN/ dtex,熔体流动性与热稳定性平衡最佳;纺丝速度4 600 m/ min时,断裂强度达3.94 cN/ dtex,有效避免了高速纺丝的熔体破裂问题;热辊温度设置为GR1 = 120 ℃、GR2 =140 ℃时,断裂强度提升至4.36 cN/ dtex,性能均匀性最优。优化后的工艺参数为运动服饰、内衣面料等民用纺织品提供了技术基础。
Abstract:
Nylon 66 semi-dull chips were used as raw material and melt spinning process was employed to prepare 70 dtex/34 f semi-dull fully drawn yarn (FDY). The effects of spinning temperature, spinning speed, and hot roller temperature on fiber properties were systematically investigated. Results show that at the spinning temperature of 290 ℃, the crystallinity reaches 22.69% and the breaking strength is 3.99 cN/dtex, achieving the optimal balance between melt fluidity and thermal stability;at the spinning speed of 4 600 m/min, the breaking strength reaches 3.94 cN/dtex, effectively avoiding melt fracture caused by high-speed spinning;when the hot roller temperature is set to be GR1=120℃and GR2=140℃, the breaking strength improves to be 4.36 cN/dtex with optimal performance uniformity. The optimized process parameters provide a technical foundation for civil textiles such as sportswear and underwear fabrics.
