TOP QUALITY HTHP Textile sampling Dyeing Machine

Once the toweling is made (it is one long terry cloth roll and has no beginning or end), it is wound on an off-loom take-up reel. It is then transported to bleaching as huge rolls of fabric and put into a water bath with bleaching chemicals such as hydrogen peroxide, caustic defoamers, and other proprietary ingredients. All toweling must be dyed pure white before it is dyed any color. The wet toweling laden with chemicals is then subjected to tremendously high temperatures. The heat makes the chemicals react, bleaching the towel. The roll is then washed at least once and as many as three times in a large washer to get all chemicals out of the toweling. The toweling is dried, and if it is to remain white toweling, it is ready to be cut at the top and bottom, lock-stitched sewn, and have a label attached (all of this is done with one machine).
