What are FDY and DTY for textile fabrics? FDY and DTY are actually spinning processing methods. They do not specifically refer to a certain material. They are mainly used for the production of polyester and other fabrics. FDY is the abbreviation of Fully drawn yarn, which is a processing method afte...

1. COMPACT YARN It is a new spinning concept and new technology. It is mainly improved on the spinning frame. The drafting system for conventional yarns (/product/conventional-product-line/) is different from the traditional spinning frame. After the output roller, an additional set of devices is ad...

We know that the function of the spinning process apron is to generate a certain friction force through the direct contact between the working surface of the upper and lower aprons and the yarn sliver, which can effectively prevent the premature speed change of the fiber and stabilize the control of...

Whether the apron can run synchronously with the middle and bottom rollers, strictly speaking, there are factors of the apron itself, spinning equipment and process environment, and whether the apron can synchronously transport the fiber to the front rubber roller for pulling under the elastic grip....

The apron is one of the important equipment of spinning Machinery, and it has a very important effect on the quality of the formed yarn. Whether the spun yarn aprons can be selected, matched and managed well during use, and whether the process status to achieve synchronous operation with the middle ...

Uneven yarn defect Uneven yarn defects are divided into regular uneven yarn irregularities and irregular uneven yarn irregularities. The irregular unevenness is all sudden yarn defects, mainly due to poor mechanical parts, improper process parameters, raw material fluctuations, and sudden changes in...
