How to adjust the knitting density of a terry warp knitting machine?

Here are some ways to adjust the knitting density of a terry warp knitting machine:

The yarn tension has a significant effect on the knitting density. It can be adjusted through the tension adjustment device. If the yarn tension increases, the yarn is stretched tighter during knitting, and the coil becomes smaller, thereby increasing the knitting density and making the fabric tighter; conversely, if the yarn tension is reduced, the coil becomes larger and the knitting density becomes smaller. However, it should be noted that excessive tension may cause yarn breakage or fabric deformation, while too little tension will make the fabric structure loose.

The needle bed distance determines the movement space of the knitting needle during the looping process. Reducing the needle bed distance will reduce the knitting needle's range of movement, shorten the length of the coil formed, and increase the knitting density; increasing the needle bed distance will lengthen the coil length and reduce the density. However, the adjustment of the needle bed distance needs to be carried out according to the specific structure of the machine and the fabric requirements. Excessive adjustment may affect the normal operation of the machine and the quality of the fabric.

The bar shift determines the yarn padding position and needle distance on the needle bed. Increasing the bar shift increases the span of the yarn between the needles, the formed coil becomes larger, and the knitting density decreases; reducing the bar shift reduces the coil and increases the density. In actual operation, the bar shift should be accurately set according to the pattern and density requirements of the fabric to achieve the ideal knitting effect.

Increasing the pulling and winding speed will cause the fabric to be subjected to greater tension during the knitting process, the coil is elongated, and the density is reduced; slowing down the pulling and winding speed will reduce the tension on the fabric, the coil shrinks, and the density increases. However, the adjustment of the pulling and winding speed must match the knitting speed of the machine, otherwise, it may cause problems such as wrinkles or uneven stretching of the fabric.
