牵伸辊温度对尼龙66工业丝热力学性能的影响

Effect of stretch roller temperature on thermodynamic properties of nylon 66 industrial yarns

摘要

研究了牵伸辊温度对尼龙66工业丝性能的影响。结果表明,牵伸机的第2对辊一段温度为177℃、二段温度为187℃,第3对辊温度为187℃时,可得到高断裂强力、低定负荷伸长率、低断裂伸长率、低干热收缩率、高干热收缩力的尼龙66工业丝,其强伸性能和尺寸稳定性良好。第2对辊温度固定时,可通过降低牵伸机第3对辊的温度得到高断裂强力、低定负荷伸长率、低断裂伸长率的尼龙66工业丝。

Abstract

The influence of stretch roller temperature on the properties of nylon 66 industrial yarns was investigated. The results showed that in the stretching machine, the temperature of the second pair of rollers was 177℃ in the first stage, 187℃ in the second stage, and the temperature of the third pair of rollers was 187℃, nylon 66 industrial yarns with high breaking strength, low constant load elongation, low elongation at break, low dry heat shrinkage rate, and high dry heat shrinkage force could be obtained, exhibiting good tensile strength performance and dimensional stability. When the temperature of the second pair of rollers was kept constant, reducing the temperature of the third pair of rollers in the stretching machine enabled production of nylon 66 industrial yarns with high breaking strength, low constant load elongation, and low elongation at break.
