Measurement problem and folding marks in dyeing

Measurement Problems:-

Definition:-

a).The measurements of the garments totally changed after a few hours of relaxation or after the first wash. The sleeve length or body length /body front or back length may be variation due to insufficient relaxation/shrinkage / steam iron or part mistake.

Causes:-

a).Shrinkage caused due to inadequate relaxation of the knitted fabrics, before cutting.

b).Mixing of the garments parts cut from different layers or different rolls.

Remedies:-

a).Let the fabrics relax for 6^th-12^th hours in the roll open relaxed condition, before cutting. Especially LYCRA fabrics.

b).Use a trolley for laying the fabrics on the table to facilitate a tension free laying.

c).Ensure the numbering or gassetsystem, so that we prevent the lay or body mixed up.    

    Folding marks:

Definition:

·       Folding marks appear as distinct pressure marks, along the length of the fabric.

Causes:-

·       High pressure of the fabric take down rollers of the knitting machine, on grey fabric is one of the main causes.

·       Too much pressure of the feeding rolls of the calendar & compactor is the primary causes folding marks in the knitting fabric.

Remedies:-

·       Adjust the gap between two rolls, as per thickness of the fabrics.(mainly in Pique, S/J, etc.).

·       Gap between two rolls of the compactor/calendar should be just enough, to let the rolls remove, the wrinkles in the fabric, but put no pressure on the fabric, especially in case of PIQUE & SINGLE JERSEY fabric.
