“…The explanation is that washing alters the surface characteristics of water repellent material, as well as the structure and stability of the fiber, resulting in decreased protection. [18] Sontara fabrics with water-repellent treatment, washed with mechanical stirring 10 times, showed a significant increase of 39% in the penetration of water after five washes, [19] highlighting the loss of protection by waterproofed fabric was caused by mechanical washing procedures.…”

Protective clothing is used as a barrier against pesticides when working with agricultural sprays. The aim of this study was to evaluate the pesticide penetration, retention, and repellence of the material and seams of a whole-body protective garment used by applicators of pesticides. The efficiency of the material and seams of the whole-body garment were determined for its classification as proposed by ISO 27065 (ISO, 2011). The evaluation method used was the pipette test of ISO 22608. The efficiency of the material and seams of the garment (100% cotton) were tested by contamination with formulations of Roundup Original® SL; Nufos EC® and Supera SC®. The presence of the seams in the protective clothing reduced its efficiency in the control of dermal exposure, except when protecting against the Supera SC® formulation. The number of washes and uses affected the efficiency of the material and seams of the garment. The type of formulation interfered significantly in the penetration of pesticides into the material and seams. Thus, the laboratory efficiency assessment of protective clothing is necessary to determine what types of formulations and use conditions are appropriate for workers.

“…Leonas and DeJonge (1986) define the barrier effectiveness of a fabric as its ability to inhibit movement of a chemical through the fabric. The degree of protection afforded by clothing is dependent on effectiveness of the garment as a barrier to pesticide penetration.…”

“…Fluorochemical-based finishes for textiles were marketed beginning in the 1950's to provide both water and oil repellency to fabric surfaces (Nuessle, 1973). Leonas & DeJonge (1986) investigated the effects of such finishes on pesticide penetration of three woven fabrics and found a significant reduction in penetration of treated fabrics. This in turn increases the interfacial tension between the fabric surface and the pesticide solution thereby reducing pesticide penetration (Orlando, Branson, Ayres, & Leavitt, 1981).…”

One of a series of papers from the S-208 Regional Research Committee. Abstract Eight nonwoven fabrics were made into experimental protective pants and worn into two types of low crop fields. Barrier properties (water penetration resistance, oil repellency, and air permeability) were measured for control fabrics and fabrics taken from pants worn in the field Results indicate that while loss of breaking strenth due to abrasion was minimal, effects of field wear on barrier properties were significant. Water penetration resistance and oil repellency were reduced and air permeability was increased for most specimens after wear in at least one of the fields. Fluorochemical finishes used on three of the fabrics were less effective after wear. The study suggests that performance of protective clothing may not be adequately assessed by testing fabrics prior to wear.

“…In the last three decades, numerous laboratory studies have been conducted in the United States to assess the performance of protective clothing materials for pesticide applicators [4,6,8,9,10,11,121. A pipette method used by researchers for over two decades has been revised and is under review as an American Society for Testing and Materials (ASTM) test method draft.…”

In the last three decades, different test methods have been used to assess the level of protection provided by various textile materials against liquid pesticide penetration. Of these, the ISO 6350/EN368 gutter test is currently used to screen garment materials for certification of type 6 personal protective equipment (PPE) in Europe. The atomizer test method developed in Germany is used to evaluate the performance of PPE marketed there. In addition, a pipette method is being proposed as an American Society of Testing and Materials (ASTM) test method in the United States. This study compares the three test methods and determines the suitability of these methods for screening protective clothing materials against liquid pesticides. Six fabrics selected to represent the woven and nonwoven fabrics used while handling and spraying pesticides are contaminated with dilute pesticide formulations following the three test methods. Repellency, pesticide retention, and penetration characteristics of the test materials are measured. The results indicate that the evaluation of fabric performance is affected by the test method.
