RECYCLE PULP COMPRISING CELLULOSE ACETATE

A recycled cellulose pulp composition is provided which comprises recycled cellulosic fibers and cellulose ester staple fibers. A wet-laid fibrous product is also provided which comprises recycled cellulosic fibers and cellulose ester staple fibers. A bailed article is also provided that comprises recycled cellulosic fibers and cellulose ester staple fibers. In embodiments， the recycled cellulosic fibers are present in an amount of 50 wt % or more， based on the total dry weight of fibers， and the cellulose ester staple fibers are present in an amount sufficient to increase the Canadian standard freeness (CSF) of the composition by 5% or more compared to a 100 wt % cellulosic fiber pulp composition processed under similar conditions.

本发明提供了一种再生纤维素浆组合物，其包含再生纤维素纤维与纤维素酯短纤维。本发明还提供了一种湿法抄造纤维制品，其包含再生纤维素纤维与纤维素酯短纤维。本发明亦提供了一种打包制品，其包含再生纤维素纤维与纤维素酯短纤维。在多个实施例中，以纤维总干重计，再生纤维素纤维的含量不低于50重量%；且纤维素酯短纤维的添加量足以使该组合物的加拿大标准游离度（Canadian Standard Freeness，CSF）相较于在相似工艺条件下制备的100重量%纤维素纤维浆组合物提升5%以上。
