Type of yarn package

1. Parallel wound package:

(a) warp yarn, (b) weavers yarn

2. Near parallel wound package:

(a) pirn, (b) cop, (c) Flanged bobbin.

3. Cross wound package:

(a) cone, (b) cheese, (c) spool

1. Parallel package or parallel winding:

This comprises threads laid parallel to one another as in a warp beam. It is necessary to have a flanged package or beam; otherwise the package would not be stable and would collapse

Advantages:

1. Many yarn can be wound at a time.

2. No need of traversing mechanism.

3. Side withdrawal is possible.

4. The density of yarn is more.

5. No change of number of turns per inch.

Disadvantages:

1. Two sides of the package need flanged.

2. for yarn

3. Cannot be over withdrawal.

2. Near parallel wound package:

This package comprises one or more threads which are laid very nearly parallel to the layers already existing on the package

Advantages:

1. No need of flanged

2. Can be side withdrawal.

3. No change of number of yarn turns per inch during winding.

Disadvantages:

1. Need of traversing mechanism

2. Cannot be over withdrawal

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 to give stability

Advantages

1. No need of flanged

2. Can be over withdrawal.

3. Yarn package is stable

Disadvantages

1. Number of yarn turns per inch is changed in this method.

2. Quality of yarn is less.

3. Need of traversing mechanism

Package used for winding:

Cotton: cone, cheese, bobbin, pirn.

Jute: cop, spool traversing
