Abstract
N-alkoxymethyl polyamides may be applied to wool from aqueous dispersions containing a surface-active agent. If an anionic agent is used, the resin can be deposited on the wool by the addition of acid. For efficient deposition, the resin-detergent ratio must be chosen such that: (a) the net charge on the resin-detergent particles is opposite in sign to the charge on the fiber surface, and ( b) the amount of detergent is insufficient to interfere with the nonfelting action of the resin. Using a sodium secondary-alkyl sulfate as anionic detergent and a resin-detergent weight ratio of 20 :1, ethoxymethyl nylon has been applied to wool fabric from aqueous dispersions at approximately pH 2.5. The felting shrinkage of the fabric can be reduced appreciably by depositing about 6% resin on it in this way.
