Cots are key equipment in spinning machinery and have great influence on yarn quality. With the joint efforts of many manufacturers and textile mills, China's spinning cots and aprons technology has developed rapidly with the development of textile technology and textile machinery, and has made considerable progress in absorbing foreign advanced technology, and basically met the needs of China's textile industry.

At present, there are about 40 enterprises in China producing nearly 200 types of spinning cots, and about 150 types of Spinning Aprons, basically covering the demand side of all kinds of domestic spinning machinery. However, the overall technical level of China's spinning cots is not high. Most of the hundreds of models in the country are derived from several original formula systems, with only a few products. Material Science There are innovations and breakthroughs in formulation and technology, and the technology level is close to the international advanced level.

Compared with the international advanced level, the gap is reflected in the following aspects: Spinnability Poor stability, short service life, production management process in application complex. From the perspective of application, all parts of China are observed.-->
