PACKAGES FOR DYEING PROCESS
Dyeing is the application of dyes or pigments on textile materials such as fibers, yarns, and fabrics with the goal of achieving color with desired color fastness.
Yarn dyeing in package form is done under high pressure, this helps in forcing the dye liquor to penetrate to the core of the yarn. Most carded and combed yarn that is used for knitted outer wear is package dyed.
The package weight and density are two important parameters which are to be standardized for uniform and trouble-free dyeing.
Factors like yarn count, winding angle, yarn tension during winding, diameter and traverse stroke, all affect the package building and must be considered while selecting a machine for package winding.
Savio winding machines for all kind of short staple yarns are suitable for dye package winding, warping preparation and rewinding with or without waxing devices. The soft package winding is the most important pre-dyeing operation, which directly affects not only the dyeing quality but also post dyeing operations such as rejects, wastages, thread breakages etc.
“Soft” packages ready for dyeing with optimal and constant density and with an accurate yarn laying, guarantee the best possible dye penetration during the dyeing phase, a perfect uniformity between the inner and outer part of the soft package.
