1·The performances of compact spun yarn and ring spun yarn are compared through experiments.

通过实验，比较了紧密纺纱线与普通环锭纺纱线的性能。

2·The flame retardant fabric developed with rotor spun PANOF yarns was obviously superior to that with ring spun yarns.

采用PANOF转杯纱开发的织物在阻燃性、耐磨性方面明显优于环锭纱织物。

3·There are some differences in quality and characteristics between ring - and rotor - spun yarns, but both have some advantages.

气流纺纱线与环锭纺纱线的质量和特点方面有一定的差异，但又具备各自的优点。

4·The band stop output characteristics of the spun elliptical birefringent fiber optic ring resonator are analysed and calculated.

对扭转椭圆双折射光纤环形腔的带阻输出特性进行了分析和计算。

5·Spinning tests on normal ring spinning frame and compact spinning frame with yarn path modified were carried out, and the performances of thus spun yarns were tested and compared.

在棉纺常规环锭细纱机和紧密纺环锭细纱机上进行了改变纱路的纺纱试验，测试对比了纱线性能指标。

6·Air-jet-spun yarns are clean, have good uniformity and even quality, but are less regular than ring-spun yarns.

喷气纺纱纺制的纱线光洁、条干均匀、质量稳定，但条干均匀度还赶不上环锭纱。

7·There are some differences in quality and characteristics between ring - and rotor-spun yarns, but both have some advantages.

气流纺纱线与环锭纺纱线的质量和特点方面有一定的差异，但又具备各自的优点。

8·In the process of spinning spun yarn, the improvement of yarn quality depends on proper rubber-covered roll, roller without mechanical wave, new type under-pin and ring.
