Chlorinated Wool

Chlorinated Wool
CHLORINATED WOOL
Wool when treated with hydrochloric acid has a high gloss, a greater affinity for dyes, but is rather harsh in feel. The process is to first clear away all greasy matter very thoroughly, then steep in hydrochloric acid solution (cold) for 20 minutes. It is next worked for 10 minutes in a solution of bleaching powder and again treated in the hydrochloric acid and finally thoroughly washed. This process is used to give a silk-like gloss to the wool. Chlorinated wool does not felt, so if woven with ordinary wool, crimped effects are obtained through one yam felting and the other not. It also takes up more dye than ordinary wool, so that two-colour effects could be obtained by dyeing in the same bath.
