The Reaction of Wool with Organic Chloroamines I–Conditions for rendering Wool Non–felting

It is shown that certain chloroamines will react with wool to render it unshrinkable, but only in the presence of high concentrations of hydrogen and ohloride ions. In the absence of high concentrations of these ions the chloroamines still react with the wool, which does not, however, become unshrinkable unless very high concentrations are employed. From a practical point of view the use of chlorosulphamic acid is most promising in the presence of high concentrations of sodium chloride, as small quantities of available chlorine then render the wool completely unshrinkable with a minimum of damage.
