Methods of Increasing Production (Knitting)

From the following methods we can increase the production of knitting. The methods are,

1. By increasing machine speed: Higher the machine speed faster the movement of needle and ultimately production will be increased. But it has to make sure that excess tension is not imposed on yarn because of this high speed. 

2. By increasing the number of feeder: If the number of feeder is increased in the circumference of cylinder, then the number of courses will be increased in one revolution at a time. 

3. By using machine of higher gauge: The more the machine gauge, the more the production is. So by using machine of hgier gauge production can be increased.

4. By imposing automation in the machine: 

a. Quick starting and stopping for efficient driving system.

b. Automatic machine lubrication system for smoother operation.

c. Photo electric fabric fault detector.

5. By imposing other developments:

a. Using creel-feeding system.

b. Applying yarn supply through plastic tube that eliminates the possibilities of yarn damage.

c. Using yarn feed control device.

Knitting Faults

Here are some knitting faults:

1. Fabric barre or stripe.

2. Press off.

3. Miss stitch/ drop stitch.

4. Needle mark.

5. Sinker mark.

6. Oil stain.

7. Crease mark.

8. Hole.

9. Excessive slubs and entanglement in the fabric.

10. Spirility.

11. Pin hole.

12. Broken needle.

13. Tight course.

14. Missing yarn.

15. Fine yarn.

16. Coarse yarn.

17. Colored fly. Etc.

Some Knit Fabric Structure

Fabric structure of some knit garments:

1. Single jersey: Face side of single jersey shows wales wise straight lines, on the other hand, back side shows course wise wavy lines.

2. Polo pique: Face side looks like honey comb and back side looks like wales wise straight lines.

3. Back pique: There are diagonally floating effect on the face side and hole on the back side.

4. Normal rib: Both sides of the fabric are looks similar.

5. Interlock: Both sides of the fabric are looks similar but less stretchable than rib.

Classification of Knitting Machine

Knitting machine mainly two types. They are:

1. Weft Knitting Machine.
2. Warp Knitting Machine.

Knitted Fabric

Mainly knitted fabrics are two types. They are:

1. Warp knitted fabric.
2. Weft knitted fabric.

Warp Knitted fabric: The structure of warp knitted each loop in vertical direction which is made from different threads and to the number of loops in horizontal row which the number of thread used to produce such a fabric at least.

Weft knitted fabric: The structure of weft knitted the loops of horizontal row which is made by using thread run or one thread in horizontal direction.

Properties of Knitted Fabrics:

1. No dimensional stability.

2. It has higher elastic property.
3. Comfortable to put on.
4. It has high extensibility and recovery property.
5. Less labor cost is needed to knit the fabric.
6. Finishing is advantageous in knitted fabric.
7. It is very soft.
8. Ironing is not necessary.
9. Fold is not created in the fabric.
