Fire-Fighting Fabric
Each year thousands of people worldwide are killed or seriously injured by fires started in mattresses. 46 . To help prevent fires in crowded public spaces, E. I. Du Pont de Nemours & Co. recently invented a fireresistant fabric(防火织物). The company claims that this fabric significantly reduces the combustibility(易燃性) of mattresses and upholstered(装有套子或垫子的)furniture. In tests conducted by a Boston-based hotel chain, the material has proved very efficient in preventing or delaying the combustion of mattresses and furniture after fires have been started. 47 . California and several other states are considering new regulations that would require the use of fire-resistant furniture in public places (defined as area where 10 or more people gather). 48 . American laws require hotels to buy fire-resistant mattress covers, though covers made of fiber glass(纤维玻璃) and cotton do exist and are used by some companies. 49 .
The Du Pont fabric will sell for less than $5 a yard and it is believed that the market will develop over the next two years. 50 .
