BROKE COMPOSITION OF MATTER

Broke pulp in a paper making process is obtained by pulping broke， and the broke pulp is made of fibrillated cellulose fibers and cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3， or a cut length of less than 6 mm， or crimped， or non-round with a DPF of less than 3. The broke pulp can be added to the stock preparation zone of a wet laid manufacturing facility and fed through a refiner.造纸过程中产生的损纸浆（broke pulp）由损纸经制浆工艺制备而成，其纤维组分包含原纤化纤维素纤维，以及满足以下任一条件的纤维素酯（cellulose ester，CE）短纤维：单丝线密度（denier per filament，DPF）小于3旦尼尔、切断长度小于6毫米、具有卷曲结构，或截面呈非圆形且单丝线密度小于3旦尼尔。该损纸浆可添加至湿法成型造纸装置的备料工段，并经精浆机处理。
