Introduction to Warp Knitting

Warp knitting:
• In a warp knitted structure, each loop in the horizontal direction is made from a different thread and the number of threads used to produce such a fabric is at least equal to the number of loops in a horizontal row.
• In warp knitting, the thread runs thoroughly in a vertical direction

Weft knitting:
• In a weft knitted structure, a horizontal row of loops can be made by using one thread and thread runs in horizontal direction.

Guide:
• Warp guides are thin metal plates drilled with a hollow in their lower end through which a warp end may be threaded if required, they are held together at their upper end in a metal lead and are spaced in it to the cam gauge as the m/c
• The leads in turn are attached to a guide bar so that the guides hang down from it with each one occupying a position at least midway between two adjacent needles in this position. The warp thread cannot be received by the needles and it will merely produce a straight vertical float. Read the rest of this entry

Requirements/ Prerequisites of fabric cutting

Cutting of fabric lay by a straight knife cutting machine.

To cut the pieces of garments from fabric lay accurately, following requirements should be fulfilled. Requirements are as following:
1. Precision of cut
2. Clean edge
3. Unfused edge
4. Support of the lay
5. Consistent cutting

1. Precision of cut: Garments cannot be assembled satisfactorily, and they may not fit the body correctly if they have not been cut accurately to the pattern shape. Precision of cut means cutting parts’ shape and size must be as per original sketch. It depends upon some factors-

• The method of cutting employed.
• The marker planning and marker making.
• In manual cutting using a knife, accuracy of cut, given good line definition, depends on appropriate, well maintained cutting knives and on the skill and motivation of the cutter.
• In both die cutting & computer-controlled cutting, the achievement of accuracy comes from the equipment.
• Skill of the operator.
