Hand Knitting (Swatch making for

The yarn before knitting needs to be dyed with

different colour. It can be done either by hank dyeing or cone

dyeing.

One of the important step before panel

making is cone winding & lubrication. The cone winding is to remove dust, dirt or

fault on the yarn before knitting. The lubrication is to reduce the yarn friction

before knitting. It is important the wax should be free of

dust and rotated freely during the winding process.

The first step is to make the panel knitting

either by Computer Knitting machine or hand machine.

The decision to make by computer or hand machine is depended on the complexity of the design.

The panel making includes front, back and sleeve , placket.

Sometimes, intarsia design will be done.

Linking is to connect different panels (front, back

and sleeve) together to form a garment. Loop to loop connection is done manually for high

quality garment. For lower quality, a simple sewing can be done.

After the linking process (front, back and

sleeve are joined together), 2nd fabric inspection will be carried out.

The inspected garment will go to washing and finishing.

This will improve the softness and hand free of the sweater before final inspection and packing.

Summary (1)

Additional processes are needed. Waxing the yarn before knitting Hank dyeing or cone dyeing before knitting. Make decision if the panel is to be knitted

by computer machine. Sample preparation is normally done by

hand machine but here use Computerized machine.

it will be develop gradually when I collect picture from floor.
