What type of fabric finish makes wool unappetizing to moths?

The type of fabric finish that makes wool unappetizing to moths is one that specifically targets the concerns of moth infestations. Moths are particularly attracted to natural fibers, especially animal fibers like wool. A moth-resistant finish often involves the use of chemicals or treatments that either repel moths or make the wool less appealing for them to eat.

This treatment helps protect wool garments and fabrics from damage caused by these pests, effectively reducing the likelihood of moth larvae feeding on the fibers. By rendering the fabric unappealing to them, a moth-resistant finish is essential for maintaining the integrity and longevity of wool apparel. In contrast, finishes such as water-resistant, stain-resistant, or fire-retardant serve different purposes and do not address the issue of moth attraction directly.
