Fungicide and mildewicide are only required for ____________ fabric.

Fungicide and mildewicide are essential for organic fabric due to its natural fibers, which are more susceptible to mold and mildew growth in humid or wet conditions. Organic fabrics, such as cotton or hemp, can absorb moisture more easily than synthetic materials, creating an environment conducive to the development of fungi. Therefore, treating organic fabric with these chemicals is important for maintaining its integrity and longevity. By applying these protective agents, the fabric's durability is enhanced, ensuring it remains functional and aesthetically pleasing over time, especially in aviation contexts where moisture exposure is common. This preventive measure is not typically necessary for synthetic fabrics, which tend to be more resistant to such growth due to their chemical composition.
