Types of Winding Package | Advantages & Disadvantages of Winding Packages

There are three types of winding packages are available in the textile weaving industry. They have lots of advantages and disadvantages too. Here are the descriptions of the three winding packages:

1. Parallel Winding Package of Weaving:

This winding package comprises many threads laid parallel to one another as in a warp beam .it is necessary to have a flanged package. For instance, Warper Beam, Weavers Beam.

Advantages of Parallel Winding Packages:

a) Many threads can be wind at a time.
b) More yarn density in the winding package.
c) Side with-drawl is possible.
d) During winding no charge of twist.
e) During winding no need to traversing.
Disadvantages of Parallel Winding Packages:
a) Need flanged packages.
b) Need separate mechanism during unwinding.
c) Over with-drawl is not possible.

2. Near Parallel Winding Packages:

This winding package comprises one or more threads which are laid very nearly parallel to the layers already existing on the package. For instance, Pirn, Cop, Flange bobbin.

Advantages of Near Parallel Winding Packages:

a) Normally no need to flange bobbin.
b) Over with-drawl can be possible.
c) During winding no change of twist.
d) The package is comparatively stable.

Disadvantages of Near Parallel Winding packages:

a) Side with-drawl is not possible.
b) During winding need traversing mechanism.

3. Cross Wound Package:

This type usually consists of a single thread which is laid on the package at an appreciable helix angle. So that the layers cross one another and give stability. For example, Cone, Cheese, Spool etc.

Advantages of Cross Winding Package:

a) Package stable due to cross wound.
b) Over with-drawl is possible.
c) During unwinding no need to separate mechanism.

Disadvantages of Cross Winding Packages:

a) The amount of yarn in the package is less due to low density.
b) Twist may be charged during unwinding.

Winding | Winding Objects | Requirements of Winding in Weaving

Weaving Winding Definitions:

The process of transferring yarn from ring bobbins, hanks, cones etc onto a suitable package is called Winding.

Objects of Winding:

1. To transfer yarn from one package to another package, which can be conveniently used for the weaving purposes.
2. To remove yarn faults like hairiness, neps, slubs, and foreign matters.
3. To produce long length of yarn by serially joining one yarn package with another.
4. To clean the yarn.
5. To improve the quality of yarn.

Requirements of Winding in Weaving:

1. Minimum fault level.
2. No damage of yarn.
3. Must permit easy unwinding.
4. Suitable size and shape of the package.
5. Economical condition and carrying.
6. Avoid of excess looseness and lightness.
7. Above all the process must be profitable.
