Cotton fiber fabric with practicability and functionality attracts much attention plays an important role in many occasions. However, its surface contains hydroxyl groups to show a hydrophilicity, leading easy adhesion stains limit the application. In this work, polyglycidyl methacrylate (PGMA) was used as oily flexible matrix graphene oxide (GO) particles were filler. PGMA/GO composite modified fabrics hydrophobicity, self-cleaning feature wear resistance prepared by constructing coatings. Compared original fabric, has hydrophobicity attributed organic characteristic of PGMA, high roughness from GO enrichment. The reasonable content (1 wt%) coating makes exhibit best overall performance (surface water contact angle ~ 151.7°; chromatism 2.4; large 140.2° after 200 cycles). This work provides effective method for industrial production high-performance waterproof cotton garment fabrics.

Cotton fabrics with the main constituent of cellulose, which is hydrophilic, bacterial infected, and flammable, are in urgent need functionalization as a kind widely applied material. To address these issues, this work, modified polyelectrolyte complex (MPEC) coatings polyethylenimine (PEI), polyphosphate (APP), perfluorodecyltrichlorosilane PEI (PFTS-PEI) prepared to construct multi-functionally gradient MPEC on cotton fabrics. Stability synergistic effects hydrophobicity, antibacterial activity, flame retardancy system have been studied. Notably, PFTS-PEI fluorine silicone elements confirmed provide hydrophobicity durability for coatings, not only has no negative effect other functions but also makes some improvement activity. This MPEC-treated fabric finally an rate against S. aureus E. coli 99.9% 96.9%, limiting oxygen index 28.5% water contact angle 118°, can be almost maintained after 20 times washing. The PEC will efficient strategy achieve durable multi-functions cellulose-based
