When the lime boil is finished the liquor is run off, and it is wellto immediately give the goods a preliminary wash with cold waterin the kier, particularly if found necessary to leave the niateiial 92 TEXTILE CHEMISTRY AND DYEING. 83 some time before running it through the washing machine. Thiscools off the goods before they come in contact with the air, andprevents them from drying while saturated with lime. As soon as possible, the goods are run directly from the kierthrough a washing machine. See Figs. 45 and 45a. The object ofthis wash is to remove the excess of lime, and any soluble sub-stances that may have been formed during the lime boil. For further discussion of the washing of Textiles see also112. 103.
