Polypropylene is a type of plastic that's highly regarded for its ability to wick moisture. This capability makes it an ideal material for a variety of applications, particularly in clothing designed for sports or outdoor activities where moisture management is crucial. Unlike natural fibers like cotton that absorb water, polypropylene fibers are hydrophobic, meaning they repel water. Instead of absorbing moisture, polypropylene fibers allow moisture to evaporate quickly, keeping the wearer dry and comfortable. This characteristic also contributes to polypropylene's quick-drying properties and resistance to stains, bacteria, and odors. Its lightweight nature, combined with moisture-wicking abilities, makes it a popular choice not only in athletic wear but also in thermal undergarments and in industries where moisture management is a priority.

Screen printing ink designed for fabric is primarily formulated to adhere to textiles, ensuring durability and flexibility on soft surfaces. However, its use on paper is feasible but not ideal. Fabric screen printing inks are thicker and may not dry as smoothly on paper, potentially leading to issues like smudging or an uneven finish. Paper-specific screen printing inks are thinner, allowing for a crisper image and quicker drying time, tailored to the absorbent nature of paper. For optimal results on paper, it’s recommended to use ink specifically designed for that medium. Although fabric ink can be used in a pinch, for professional or lasting work, choosing the right ink for the intended surface is crucial.

Chemical solvents used in coatings can indeed cause skin burns, depending on their chemical composition and the duration of exposure. These solvents often contain chemicals like toluene, xylene, acetone, and ethyl acetate, which are known to have varying levels of skin irritancy. Direct contact can remove oils from the skin, causing dryness, irritation, or chemical burns in more severe cases. The severity of the burn typically depends on the concentration of the solvent and length of contact with the skin. Protective measures such as wearing gloves and protective clothing are essential when handling these chemicals to prevent skin burns. In case of exposure, it's crucial to wash the affected area with plenty of water and seek medical attention if necessary.
