In protecting textiles from insects, concern arises for the damage that the pesticidal chemical itself may cause to the textile object. A preliminary study was undertaken to assess this. Cotton and wool were each dyed with four natural dyestuffs. The dyed fabrics were exposed to pesticide-related chemicals for varying periods. Chemicals used were CCl 4 (fumigant), dichlorvos (pest strip), petroleum distillate spray (carrier), and boric acid dusting. Instrumental colorimetry was used. There was no color change from CCl 4 except for safflower-dyed wool after three years. Dichlorvos-treated samples varied, with some exhibiting a slight change. Petroleum distillate was hardly visible; most residue dissipated with no color change. Boric acid deposits were visible, but lessened after three years. Exceptions were strong color change on some wool samples. Breaking strength also was determined. Contact of the cotton by CCl 4 resulted in degradation.
