Large Capacity Bobbin Rewinding Machine

DT2002 High-speed yarn rewinding machine is the pre-equipment of DT series compound twister.

Driven by double-faced Swiss-made belt, owning Japanese Mitsubishi frequency conversion control to form yarns and threads, maintaining thread making in constant speed and preventing anti-overlapping.

Main Technical Date:

As the last process of spinning and the first process of weaving, the winder plays a role as a "bridge" between succession and failure, and therefore plays an important role in the textile field.

The main task of winding

1. Change the package and increase the capacity of the yarn package:

The bobbins (or skeins) with less capacity are connected by winding to make bobbins with larger capacity. The capacity of a bobbin is equivalent to more than twenty bobbins. The package can be used for warping, twisting, weft winding, dyeing, weft yarns on shuttleless looms and knitting yarns. If these processes directly use bobbins, it will cause too much downtime, affect the improvement of production efficiency, and also affect the improvement of product quality. Therefore, increasing the package capacity is a necessary condition to improve the productivity and quality of the subsequent process.

2. Remove the defects on the yarn and improve the yarn quality:

There are some defects and impurities on the yarn produced by the cotton spinning mill, such as thick knuckles, details, double yarns, weak twisted yarns, neps, etc. During winding, the yarn clearing device is used to check the yarn, remove the defects and impurities on the yarn that affect the quality of the fabric, improve the uniformity and smoothness of the yarn, and help reduce the yarn breakage in the subsequent process To improve the appearance quality of the fabric. The defects and impurities on the yarn are the most reasonable to be removed in the winding process, because the work of each package is carried out independently during winding, and when a package is broken, other packages can continue to work without being affected.

Winding process requirements

1. Appropriate winding tension does not damage the original physical and mechanical properties of the yarn.

2. The package volume of the package is large and the shape is good, which is convenient for unwinding.

3. The yarn joint is small and strong, and try to form no-knot yarn.

4. The length of the package used for warping should be fixed, and the structure used for dyeing package should be uniform.
