AATCC 24 – Insects, Resistance of Textiles to

1. Purpose and Scope

1.1Biological test methods are given for evaluating the resistance of textiles that contain wool or other susceptible fibers to webbing clothes moths and to carpet beetles. The test methods described here are not concerned with the various procedures for treating textiles [e.g., dyebaths vs padding application of mothproofers] or with their subsequent handling, ageing, washing, etc. but only with their biological methods to be used to measure resistance of the [treated or untreated] textiles to insect attack (see 15.1)

2. Principle

2.1 These methods measure quantitatively the amount of feeding on the test specimen by the specified number and type of insects for a prescribed time under controlled conditions of temperature and humidity.
