Winding is the process where yarns are transferred from bobbins, rings, and hanks into a more convenient packaging like cones, pirns, cops, etc. Both warp and weft yarns are wound on different components. Where warp yarns are wound on cheese, cone, and flanged bobbin packages; weft yarns are wound on cops and pirns packages. You can get all of these of the finest quality at Trim Engineering Services, one of the leading bobbins, cops, and pirn manufacturers in India.

Why is winding of yarns important?

Winding of yarns is done not only to make it easy for the users to use the thread, but for various other purposes.

• Yarn winding cleans the yarn, thus improving its quality, which in turn improves the quality of the fabric made from the yarn.
• By winding, the long length of the yarn is kept intact, which would otherwise break and damage if kept untidy.
• Yarn winding removes various kinds of faults present in the yarn, such as slubs, hairiness, and neps.
• Winding the yarns helps to empty spinner’s bobbin so that it can be used again, and also to increase the efficiency of yarn for the next processes; thus increasing productivity.

What are the requirements of yarn winding?

To have an effective yarn winding process, there are various requirements that need to be fulfilled.

• The size, shape, and hardness of the winding package should be correct.
• The yarn should be devoid of any faults and damage while being wound.
• The characteristics of the yarn should not be altered, and excessive looseness or tightness should also be avoided.

What are the factors of winding efficiency?

Winding efficiency is the ratio of actual production and the calculated production, which is expressed as a percentage. Note that the calculated production is always higher than actual production in this case. There are certain key factors associated with this winding efficiency, which are stated below.

• Yarn count – Higher the yarn count, higher the winding efficiency.
• Yarn quality – Improved yarn quality means an increased winding efficiency.
• Work load – If the work load per worker increases, the winding efficiency will be decreased.
• Worker efficiency – If worker efficiency increases, the winding efficiency also increases.
• Power failure – If power failure increases, the winding efficiency will decrease.
• Capacity utilization – It more capacity utilization is observed, the winding efficiency decreases.
• Winding machine quality – If the maintenance and over hauling of the winding machine is not perfect, the winding efficiency is decreased.
• Drum speed – If the drum speed is more, the winding efficiency is increased.
• Humidity – In the case of cotton yarns, increased humidity results in increased winding efficiency. But, in the case of other yarns, increased humidity means decreased winding efficiency.
• Creeling time – If the creeling time is more, the winding efficiency becomes lesser.
• Doffing time – If the doffing time is more, the winding efficiency is lesser.

Thus, if you want an increased winding efficiency, you need to have a higher yarn count, improved yarn quality, increased worker efficiency, maintained winding machine, and high drum speed. And, you need to ensure that the work load on every worker is kept low, the capacity utilization is less, and there is no power failure. Also ensure that the creeling time and doffing time is less.
