Winding is one of the most important processes that winds the yarn or thread onto a bobbin or pirn before stitching and weaving a fabric. It is the process of transferring yarn from small packages to a large package containing considerable length of yarn. This is done to remove objectionable faults like slubs, doubling yarn, or thick/thin place in the yarn. Trim Engineering Services is one of the most reliable pirn manufacturers in India who manufactures not only pirns, but also other wound packages like bobbins, cops, spools, and more to provide the best quality parts and accessories to the textile industry.

There are various types of winding packages available like parallel winding, near parallel winding, and cross winding. Each winding has its own advantages and disadvantages. Let us learn about each of the winding processes below, along with the pros and cons of each.

Parallel winding/parallel wound package

As the name suggests, this type of winding packages have the yarn wound parallel to each other on the package containing flanges on both sides of the package. Here, there is no requirement of a traversing guide.

Pros – In this type of winding procedure, multiple yarns can be wound at a time. Moreover, there is no change of twist during winding, nor is there a change in the number of turns per inch. However, there is a possibility of side withdrawal here. As mentioned above, there is no need of a traversing mechanism in parallel winding. Finally, the yarn density in this case is more, and the package is stable.

Cons – In this process, there is no possibility of over withdrawal. Also, two sides of the winding package need to be flanged, and there is a separate mechanism needed for yarn unwinding.

Near parallel winding/near parallel wound package

In this type of winding process, the package contains one or more yarn laid very nearly parallel to the layers, which already exist on the winding package.

Pros – There is no requirement of a flange here. Over withdrawal is possible, and there is no change in the number of yarn turns per inch or per twist.

Cons – In the case of a near parallel winding process, a traversing mechanism is required. Moreover, side withdrawal is not possible, and the resulting package is also not stable.

Cross winding/cross wound package

You already know that as the name suggests, cross winding contains a cross or an angle somewhere. Well, it’s true. In a cross winding package, there is a single yarn that is laid on the package at an appreciable helix angle so that the layers crossing one another provide stability.

Pros – In the case of a cross winding package, flange is not required, over withdrawal is possible, and the yarn package is very stable.

Cons – In a cross winding package, the yarn quality is reduces, and the yarn twist is changed during winding. Moreover, a traversing mechanism is required.
