Yarn Dyeing:
Yarn dyeing is slightly
difference from woven or knit dyeing. Yarns are
dyed in package form or hank form by yarn dyeing process. Dyeing
process can be vary depending on the individual procedure of
a textile engineer or a dyeing master. Dyed yarns are used for making stripe
knit or woven fabrics or solid dyed yarn fabric or in sweater manufacturing.
Yarn dyeing starts from soft winding to packaging. Here production parameters
of all section of yarn dyeing are point out below.
