Hardwood pulp having a tactile sense of softness, and tissue paper webs thereof

摘要: Pulps having a tactile sense of softness which are made from hardwoods and processes for making such pulps. The process comprises the steps of: providing hardwood chips specified sizes; introducing into digester; removing substantially all free oxygen within cooking liquor comprising about 0.4% to 3% ammonia 9% 14% sulphur dioxide; completely submerging in sulfonating lignin at temperature less than 110° C.; rapidly increasing an appropriate hydrolysis temperature; hydrolyzing sulfonation products 140° 155° C. pH 2 3; reducing system following hydrolysis. by this were useful tissue paper webs enhanced properties.
