摘要：

针对现有纱线耐磨测试仪因测试工况较织造状态存在较大差异,难以满足浆纱耐磨性能测试的问题,为提高浆纱耐磨性能的测试水平,设计了一种模拟织造状态的浆纱耐磨测试仪器:JN-01浆纱耐磨测试仪。该仪器由送经机构、卷取机构、开口机构、打纬机构和纱线张力自适应调节机构组成,可以保持测试过程中纱线张力恒定和负载的稳定性。在实际测试纱线耐磨寿命的基础上,探讨了样本数对测试结果的影响,确定以5组共50根浆纱为实验样本。分别在JN-01浆纱耐磨测试仪和LFY-109A型电脑纱线耐磨仪上,通过3种线密度原纱和浆纱的耐磨寿命测试,验证了JN-01浆纱耐磨测试仪测试结果的稳定性。结果表明,该浆纱耐磨测试仪可以满足测试要求。

Abstract:

The existing yarn abrasion resistance tester is unable to obtain accurate results due to the great difference between the testing condition and the weaving state. To improve the abrasion resistance test accuracy of the sized yarn, an new abrasion resistance tester(JN-01 Sizing Abrasion Tester) was designed and constructed, which closely simulate the weaving conditions.The tester involves the let-off mechanism, take-up mechanism, shedding mechanism, beating-up mechanism, and a yarn tension adaptive adjustment mechanism. It is able to maintain a constant yarn tension and load stability during the test. Based on the actual test of the yarn abrasion resistance, the influence of the number of samples on test results was discussed, and a total of 50 sized yarns in 5 groups were determined as test samples. Through testing the abrasion resistance of raw and sized yarns on JN-01 and LFY-109A Yarn Abrasion Tester for three levels of fineness, the stability of JN-01 Sizing Abrasion Tester was verified, which could meet the test requirements.

Key words: weaving, sized yarn, abrasion resistance, yarn tension, opening stroke, swinging angle of reed-base
