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 6th-12th 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.
