中文摘要：使用双立柱电子万能材料试验机,选择4个不同的勾结位置、4种不同的拉伸速度,设定3种夹持距离,对4种涤纶FDY长丝的勾结断裂强力和伸长率进行测试。结果表明:长丝未勾结的强力和断裂伸长率之比比勾结状态下的大,勾结位置越偏离中心位置,强力越大,而勾结位置对勾结断裂伸长率影响不明显;夹持距离在100 mm到500 mm,长丝勾结后强力和断裂伸长率遵循"弱环定律";随着长丝纤度的增加,强力呈逐渐递增趋势,而断裂伸长率随纤度变化不明显。

外文摘要：The hook strength and breaking elongation of four kinds of polyester filament were tested with double-column electronic universal material testing machine. The hook testing parameter includes： four hook positions, four stretching speeds and three clamp distances. Conclusions are as follows： the strength of filament becomes smaller when the filament was hooked; the more off center of hook position, the hook strength are greater, while the hook position has little impact with elongation ratio; the hook strength and breaking elongation keep with ＂weak laws＂ when the clamp distances range from 100mm to 500mm; at last along with the increase of thread density of filament, the hook strength increases gradually, while the elongation at break with thread density change is not obvious.
