ABSTRACT:
A cold padding batch dyeing process for a tubular knitted fabric comprises feeding the fabric into a padding tank, subjecting it to air inflating, blowing compressed air into the fabric to expand it into its original tubular shape, squeezing the fabric at a squeezing rate of 95 to 120% by passing it between a pair of mangles each having a layer of rubber having a Shore hardness of 55 to 70, and leaving the fabric for ageing over a period of at least four hours. The length of time between entry of the fabric into the padding tank and its departure from the mangles is controlled to 10 to 20 seconds.
