Knitting is done by set of connected loops from a series of yarn in warp or weft direction. Knitted fabrics are divided into two main types; they are
- Warp knitting
- Weft knitting
Warp knitting: In a warp knitted structure each loop in the horizontal direction is made from different thread. Sweater is made by this warp knitting techniques.
Weft knitting: In a weft knitted structure a horizontal row of loops can be made using one thread and the thread runs in the horizontal direction. Most of the knitted fabrics are produced by weft knitting.
Difference between warp and weft knitting: Basically warp and weft knitting process are totally different from one to another. Following are the difference of warp and weft knitting.
| Warp Knitting | Weft Knitting |
|---|---|
| The loops are produced to the length of fabric. | The loops are produced to the width of the fabric. |
| It is elastic to the length. | It is elastic to the width. |
| Elasticity of the warp knitted fabrics is less than weft knitting. | Elasticity of the weft knitted fabrics is higher than warp knitting. |
| Its shrinkage properties is less. | Its shrinkage properties is higher than warp knitted fabrics. |
| Here courses are needed for each pattern row. | Courses are equal to the pattern. |
| Yarns are supplied from beam. | Yarns are supplied from cone. |
| At least one yarn is required for each needle. | Any number of needle. |
| Creating fabric by this method is suitable to dry wash. | Hand wash is suitable for weft knitting. |
| Any design is done easily. | All types of design is complex. |
| It is specially suitable for producing coarse fabric. | It is suitable for producing thin fabric. |
