: Dyeing

Yarn is changed from its natural color to the color and shade specified by the customer by processing through a rope dye indigo range. Ball warps are placed on stands which allow the warped yarns to unroll as the ropes are pulled into the dye range. Dyeing is accomplished by passing the yarn through a vat containing liquid dye and then through what is known as skying allowing the yarn to oxidize in open air between each dip into the dye bats. The yarn goes through a series of vats depending on the dept of shade desired. Darker shades are produced by chemical concentration, speed and the number of dips involved. The yarn is then coiled on pallets for transport to beaming.
