Drying products including blends of conventional papermaking fibers and microalgae, and particularly dry tissue substrates, are disclosed herein. The use of cationic retention enhancers on dry tissue substrates helps provide tissue sheets that retain microalgae without compromising tissue properties such as caliper, bulk, air permeability, desorption, and absorbent capacity. In addition, the use of flocculants can make it easier to aggregate microalgae to retain microalgae in the tissue sheet. |
