喷丝板是纺丝机的重要部件之一，它的作用是将黏流态的高聚物熔体或溶液，通过微孔转变成有特定截面状的细流，经过凝固介质或凝固浴固化而形成丝条。

Spinneret is one of the most important parts of spinning machine. Its function is to change the viscous polymer melt or solution into a specific cross-section flow through micropores, and then solidify in the coagulation medium or coagulation bath to form filaments.

在纺丝过程中喷丝板会被机械杂质、碳纤、凝胶等堵塞喷丝孔，当喷丝孔部分堵塞时，在喷丝头/板外表面会有纺丝溶液漫流，从而造成原丝纤度不匀和产生丝细、丝毛等问题。而当喷丝孔完全堵塞时，则会大大提高纤维的断头率，对纤维品质有极大的影响，因此必须定期对喷丝板进行清洗。

In spinning process, spinneret will be blocked by mechanical impurities, carbon fiber, gel and so on. When the spinneret is partially blocked, the spinning solution will overflow on the outer surface of spinneret / plate, resulting in uneven yarn size and thin silk and wool. When the spinneret hole is completely blocked, the fiber breakage rate will be greatly improved, which has a great impact on the fiber quality. Therefore, the spinneret must be cleaned regularly.

传统的喷丝板清洗方法如化学、物理或机械会使喷丝孔磨损以致出现侵蚀、微裂、孔径不规则等问题，因而要选用清洗效果好且不会对喷丝孔造成损伤的清洗方式，为喷丝孔堵塞及清洗工艺会对喷丝孔造成损伤的问题，现在很多工厂采用超声波清洗机来清洗喷丝板。

Traditional spinneret cleaning methods, such as chemical, physical or mechanical, will make the spinneret hole wear and tear, resulting in erosion, microcracking, irregular aperture and other problems. Therefore, it is necessary to choose the cleaning method with good cleaning effect and no damage to the spinneret hole. In order to solve the problem that the spinneret hole is blocked and the cleaning process will cause damage to the spinneret hole, now many factories use ultrasonic cleaning machine to clean the spinneret Silk board.

超声波清洗是目前工业上应用广泛且效果好的一种清洗方式，其工作原理是超声波在清洗液传播时，清洗液中的微小气泡在声场的作用下产生振动，当声压达到一定值后，气泡会迅速增大，然后闭合瞬间爆破产生可达到上千个大气压的冲击波，冲击波减小了污渍与被清洗工件的粘着力，可以破坏不溶性污渍而使它们分散在清洗液体中，从而达到清洗的目的。虽然气泡的破裂能量很高，但是因每个气泡的体积非常微小，对于工件来说不会产生机械破坏和明显的温升。

Ultrasonic cleaning is a widely used and effective cleaning method in industry. Its working principle is that when the ultrasonic wave propagates in the cleaning solution, the tiny bubbles in the cleaning solution will vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles will increase rapidly, and then close and explode instantly to produce shock wave which can reach thousands of atmospheres. The shock wave reduces the dirt and dust The adhesive force of the cleaned workpiece can destroy the insoluble stains and disperse them in the cleaning liquid, so as to achieve the purpose of cleaning. Although the bubble rupture energy is very high, but because the volume of each bubble is very small, there will be no mechanical damage and obvious temperature rise for the workpiece.

在清洗液中由于空化效应产生的气泡数量众多且无处不在，因此对于工件的清洗可以非常彻底，即使是形状复杂的工件内部，只要能够接触到清洗液，就可以得到彻底的清洗。所以只要将喷丝头/板浸入清洗液中，其各个部位都可以得到充分的清洗，包括深孔、狭缝和凹槽。

In the cleaning solution, due to the cavitation effect, the number of bubbles is numerous and everywhere, so the cleaning of the workpiece can be very thorough, even the inside of the workpiece with complex shape, as long as it can contact with the cleaning solution, it can be thoroughly cleaned. Therefore, as long as the spinneret / plate is immersed in the cleaning solution, all parts of the spinneret / plate can be fully cleaned, including deep holes, slits and grooves.

超声波清洗喷丝板与其他清洗方法相比具有清洗效果好、用时短、节省成本、操作方便等优势，因而采用超声波清洗技术清洗喷丝板是理想的清洗方法。随着纺织行业的发展，采用超声波清洗喷丝板的企业也会越来越多，超声波清洗机在纺织业将会得到更多的应用。

Compared with other cleaning methods, ultrasonic cleaning of spinneret has the advantages of good cleaning effect, short time, cost saving and convenient operation. Therefore, ultrasonic cleaning technology is the most ideal cleaning method for spinneret. With the development of textile industry, there will be more and more enterprises using ultrasonic cleaning spinneret, and ultrasonic cleaning machine will get more application in textile industry.
