“…Finding substances that can fortify paper has been the subject of some studies. Aminoalkylalkoxysilane copolymer, 15 carbon nanotubes/graphene oxide nanocomposite cross‐linked by copper ions, 16 poly(diallyldimethylammonium chloride) containing hemp pulps, 17 polyphenylene sulfide composite with aramid chopped fibers, 18 chemically modified hemicelluloses by carboxymethylation, 19 gum Arabic, 20 2,3‐epoxypropyl trimethyl ammonium chloride, 21 laccase‐TEMPO system, 22 Ag‐functionalized nanocrystalline cellulose, 23 and magnesium hydroxide 24 were all used as strengthening agents in papermaking. Looking for another opportunity in the paper industry, these studies have pointed to strengthening agents for papers, rather than modifying recycled pulp fibers.…”

Although styrene acrylate emulsions (SAE) have demonstrated promising applications as surface sizing agents for paper, their strengthening effect on pulp fibers in papermaking is not clear. In this study, bagasse fibers, an agricultural waste, were treated with SAE to study the influences on the mechanical properties of the produced papers. SAE copolymers with hard chain (H‐PSA) and soft chain (S‐PSA) were prepared and added to bagasse pulp slurry at concentrations of 1%–4% by weight. The findings indicated that for the soft and hard copolymers, the glass transition temperatures were 19.5 and 26.8°C and their emulsion particle sizes were 166 and 182 nm, respectively. The copolymers strengthened the produced paper by wrapping around and forming a network of chemical and physical bonds with the pulp fibers. Papers treated with 3% H‐PSA exhibited the optimum improvement in tensile strength (38 MPa) and breaking length (67 m) by 13% and 64%, respectively. Treated papers were negatively affected by UV radiation due to phenyl groups spread along the chains. The copolymers demonstrated good wet‐strength properties achieved by self‐ and co‐crosslinked networks. The prepared paper sheets showed a preference for the mechanical properties of treated samples over the untreated ones.

Paper has been used in the field of hygiene for centuries. Tissue papers have low grammage, creped or non-creped surface, and consisting of one or more layers from virgin papers. Toilet paper, which has an important area of use, comes at the beginning of the tissue papers divided into various product groups. Its use has increased even more with the effect of the coronavirus pandemic. Increasing use of toilet paper causes clogging in sewers as solid waste. Because an important and large part of the sewage is composed of cellulosic structures. Therefore, the disintegration of toilet paper is an important issue. The main properties of toilet paper are characterized by grammage, thickness, polymerization degree, softness and wet tensile strength. This study, it was aimed to determine the relationship between the degree of polymerization, thickness, grammage, softness and wet tension strength of toilet papers, which accumulate in the sewer pipes and cause clogging, and their disintegration in tap water and pure water at environment of different pH levels. A great level and positive linear relationship was found between grammage and in disintegration pH9. It was determined a low level and positive relationship with wet tensile strength in disintegration tap water.
