To have the level of fourth-generation technology, thanks to good fortune by the German-made automatic winding machine AC338 for example, with the third-generation type of comparison, the practical winding speed of nearly 30 percent, most can be as high as 2 000 m / min;筒纱quality increased yarn Uster CV value of the two machines are basically the same though, but the quality of yarn, such as details of 1000 meters from 14.5 to 12, 17.24 percent lower; km thick section from 134.3 to 121.7 , 9.38% lower; Neps kilometers from 121.6 to 115.5, lower 5%; 3 mm in length Hairiness (months / 10m) from 135 down to 102, reduced 24.4%; 14.36% increase in production; production efficiency 8.5%, not筒纱the use of high-quality, the following procedures brought about by economic interests.

以具有第四代技术水平的，由德国赐来福公司制造的AC338型自动络筒机为例，与第三代型机比较，实用卷绕速度提高了近30%，最可高达2 000 m/min；筒纱质量大幅度提高，乌斯特条干CV值两机虽然基本相同，但纱的质量如千米细节由14.5降至12，降低了17.24%；千米粗节由134.3降至121.7，降低了9.38%；千米棉结由121.6降至115.5，降低了5%；3 mm长度毛羽(个/10m)也由135降到102，降低了24.4%；产量提高14.36%；生产效率提高8.5%，这还不算使用高质量的筒纱后，后道工序所带来的经济利益。
