摘要： Kitchen roll toweling having surprising softness, absorbency and bulk is formed from a furnish comprising long cellulosic fiber having: (i) average weight-weighted fiber length of at least 2.5 mm; coarseness at least 15.5 mg/100 mm; and a Canadian Standard freeness of at least 600 ml combined with (ii) short cellulosic fiber having an average weight-weighted fiber length of at most 1.9 mm having a Canadian Standard freeness of at least 500 ml in a weight ratio of short fiber to long fiber of at least 0.25 to 1.0 to form a nascent web having a consistency in the range from about 10% to about 35% which is rush transferred from one fabric to another at a speed differential of at least about 15%, and creping the web from a Yankee dryer while controlling the real crepe to at most 3% and thereafter converting the web to form a two ply product having a basis weight of at least 29 lb/rm and caliper of at least 220 mils/8 sheets.
