Abstract

With the increasing threats of chemical and biological warfare, the development of protective clothing that can shield the human body from hazardous substances has become critical. This study investigates the washing durability of chemical, biological, radiological, and nuclear (CBRN) protective clothing by examining the effects of different types of activated carbon and inner fabric structures. Activated carbon beads (ACB) and activated carbon fibers (ACF) were used, with ACF further classified into ACF(W), composed of woven fabric, and ACF(N), composed of non-woven fabric. Each sample underwent 30 washing cycles, and performance was evaluated in terms of dimensional stability, colorfastness, air permeability, moisture vapor transmission rate (MVTR), and protective performance. ACB and ACF(N) demonstrated greater shrinkage owing to their nonwoven structures, although all the samples met the U.S. military standards (shrink- age < 6%, skewness < 3%). In terms of colorfastness, ACB remained stable for up to 10 washes, whereas ACF exceeded the fading threshold from the first wash. The air permeability and MVTR retention followed the order ACB < ACF(W) < ACF(N), with ACF(N) showing the most stable results. The ACF samples also demonstrated longer breakthrough times and superior protective performance compared to ACB. The durability of ACF is attributed to its uniform pore dis- tribution and high surface area, which enhances adsorption and airflow. Additionally, the woven structure of ACF(W) pro- vides a stable network that maintains air permeability and protection. Although performance degradation appeared after 10 washing cycles, ACF demonstrated overall advantages in terms of durability as well as protection. These results indi- cate that ACF materials are suitable for long-term use in CBRN protective clothing.
