Abstract: A hot-extraction paper consisting substantially of cellulose and manufacturing assistants needed in cellulose and manufacturing assistants needs in cellulose production, such as pH modifiers based on acids and/or bases, the paper comprises exclusively cellulose having fibre lengths of at least 2.0 mm on length-weighted average, more particularly at least 2.5 mm on length-weighted average, and has isotropic extension properties which are substantially equal in machine and cross directions and amount to at least 7.5%, more particularly at least 8.5%.
