Piezo Jacquard Maintenance Knowledge

Piezo Jacquard is used on warp knitting machines as one of the most advanced technologies in recent decades. So far, the piezo jacquard has already been applied in Raschel jacquard warp knitting machines, lace warp knitting machines, double-needle bar Raschel warp knitting machines, terry tricot warp knitting machines, and even high-speed tricot machines, such as TSJ3/1.

In this article, A-ZEN warp knitting technology company presents to the readers how to operate and maintain of piezo jacquard elements.

With cotton yarn widely used in jacquard warp knitting machines nowadays, good maintenance is required. Recently, we have received some jacquard elements that fail to work well, while after checking the jacquard detector, we found that most of the failures are caused by bad maintenance.

Here is one example of the importance of the removal of the cotton fly from jacquard needles. 

1. Cotton yarn or other dirt in the jacquard needles:

One jacquard needle is filled with the cotton fly, which makes the needle pins heavy to move.

With more dirty elements accumulated, the piezo jacquard fails to work. 

2. Incorrect manner harms the piezo elements:

Some workers hold the piezo jacquard in an incorrect manner, which could harm the piezo element inadvertently. 

We shall take out or put back the piezo jacquard needle elements on the top cover, avoiding touching or pressing the piezo element directly. 

3. Check the piezo jacquard by the Jacquard Detector tool

We can use a special jacquard detector tool to test the jacquard condition and tell if it can still be put into use or needs to be replaced. 

Regular maintenance is a good partner of jacquard elements.
