Mothproofing is an essential part of the manufacture of wool and wool‐blend carpets and until now has usually been combined with another textile wet process, such as dyeing, to save cost. Environmental quality standards for mothproofing agents in surface waters have recently been introduced. Compliance with these standards will require a reduction of more than 90% in the mothproofing agent content of industrial effluents in parts of the UK where mothproofing activity is most concentrated. In order to achieve such a reduction, it is proprosed that the carpet industry should install new methods of applying mothproofing agents, aimed at source reduction, rather than by adopting end‐of‐pipe measures. Two new low‐pollution mothproofing technologies are described in detail, and a summary is given of other possibilities.
