5、The movement of liquidpesticides through these materials is primarily a result of penetration through spaces between fibersand interstices between yarns.As these materials provide protection either by repelling or retainingliquid pesticide,the measurement of these properties is also important.This t
6、est method is used tomeasure repellency,retention,and penetration of liquid pesticides through protective clothingmaterials.The degree of contamination depends on numerous factors such as type of exposure,applicationtechnique,and pesticide formulation.Worker exposure to liquid pesticides can range f
