摘　　要：利用纺粘非织造设备制备锦纶6(PA 6)粘合纤维,研究了泵供量、拉伸气流强度和纺丝温度对PA6粘合纤维结构和力学性能的影响。结果表明:纤维结晶度随着拉伸气流强度的增加而增加;纤维直径随着泵供量减小和拉伸气流强度增加而减小;纤维的断裂强度随着拉伸气流强度的增加而增加,纤维的断裂伸长率随之逐渐减小;泵供量和纺丝温度对纤维的结构和力学性能影响较小;当纺丝温度为240℃,泵供量为96m L/min,拉伸风电机频率为40 Hz时,所制得的PA 6纤维直径为26.7μm,断裂强度为2.36 c N/dtex,断裂伸长率为1 760.2%。Polyamide 6 （ PA 6） bonding fiber was prepared on a spunbond non-woven equipment .The effects of the pump de-livery, quenching air intensity and spinning temperature on the structure and mechanical properties of PA 6 fiber were studied . The results showed that the crystallinity of PA 6 fiber was increased with the increase of quenching air intensity;the fiber diame-ter was decreased with the decrease of pump delivery and the increase of quenching air intensity ;the breaking strength of the fiber was increased and the elongation at break was decreased with the increase of quenching air intensity ;the pump delivery and spin-ning temperature gave a slight effect on the structure and mechanical properties of the fiber ;and the PA 6 fiber could be produced with the diameter of 26.7 μm, breaking strength 2.36 cN/dtex and elongation at break 1 760.2%under the conditions of spin-ning temperature 240 ℃, pump delivery 96 mL/min, quenching air motor frequency 40 Hz.
