 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)

43.  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.
