主要从设备入手,对影响锦纶6拉伸变形丝(DTY)断裂强度和断裂伸长率的因素进行分析和试验论证。实践证明:调整摩擦盘和拉杆导丝器或止捻器对改善DTY的断裂强度和断裂伸长率有一定作用;拉杆导丝器和止捻器的相对位置对DTY断裂强度和断裂伸长率影响显著,丝束加弹时先经过止捻器后经过拉杆导丝器会使DTY的强度和断裂伸长率明显提高。
Mainly from the equipment, the impact of nylon 6 tensile strength (DTY) rupture strength and elongation at break of the factors that are analyzed and demonstrated. Practice has proved that: adjusting the friction plate and rod guide or twist stop device to improve the breaking strength and elongation at break of DTY have a certain effect; rod guide and twist-twister relative position of the DTY breaking strength and elongation at break The effect is obvious, when the tow is added, the strength of the DTY and the elongation at break are obviously improved after passing through the twist rod guide after the twist stop.
