Step 1: Understanding Textile Finishing Agents: Various chemical agents are applied to textiles to impart specific properties.
Step 2: Identifying Benzotriazoles: Benzotriazoles are a class of chemical compounds that are very effective at absorbing ultraviolet (UV) radiation. They are commonly used as UV stabilizers or UV absorbers in textiles, plastics, and coatings to protect the material (and the wearer, in the case of clothing) from the damaging effects of UV light.
Step 3: Eliminating Other Options:
Antimicrobial agent: These kill or inhibit the growth of microorganisms.
Antistatic agent: These reduce static electricity buildup.
Wetting agent: These reduce the surface tension of water, allowing it to spread more easily on a fabric.
