Thaw at room temperature and mix before using.
Uses: Teculube HNF Special is an effective fiber to fiber lubricant for jet dyeing of Polyester fibers with disperse dyes. The product also acts as a dispersing agent for both dyestuffs as well as trimers. Teculube HNF Special foams slightly. Teculube HNF Special is used in quantities that are dictated by the equipment and the liquor ratio, as well as the severity of the problem. At short liquor ratio’s, i.e. 1 – 5 to 1 – 10, as on jets, we recommend to use 0.5-1.0% calculated on the weight of the goods. Longer liquor ratio’s may require larger amounts, e.g. 1.0 – 2.0% owg. Teculube HNF Special is mixed with water. Mix well, and then add to the dyebath at the beginning of the dye cycle.
