AATCC Test Method 28-2004
Insect Pest Deterrents on Textiles

Developed in 1940 by AATCC Committee RA49; Transferred to RA31 in 1994; and returned to jurisdiction of RA49 in 2000

1.  Purpose and Scope

1.1  This test method covers procedures for the evaluation of compounds or treatments designed to protect textile fabrics and yarns from damage by insect pests, such as moths or carpet beetles.  They comprehend not only the initial protection furnished by the treatment, but also the permanency of the protection during conditions of ordinary service.

2.  Principle

2.1  Treated and untreated specimens are subjected to the action of insect pests under controlled conditions for one exposure period and then examined for evidence of damage.  Additional exposure periods are given as necessary until visual damage is evident.
