What material should clothes worn during welding be made of?

Clothing worn during welding should be made of 100% cotton because this material provides a good balance of comfort and fire resistance. Cotton fabrics can help protect the skin from the intense heat generated during welding and can absorb sweat, which adds to comfort during long periods of work.

While cotton is not inherently flame-resistant, it does not melt or adhere to the skin, making it a safer choice compared to synthetic materials like polyester, which can melt and cause severe burns. Denim, while generally made from cotton, may not provide adequate protection due to its weave and treatment. Leather is indeed a great material for welding gear due to its superior heat and abrasion resistance, but it is not as commonly used for everyday clothing and may not be as comfortable for all-day wear compared to 100% cotton options. Therefore, 100% cotton is favored for general welding apparel.
