Özet

Superabsorbent polymers (SAPs) constitute a special class of polymers widelyused in various fields, especially in the hygiene and healthcare sectors. Thisstudy investigates the feasibility of achieving high water absorption capacitysurfaces by coating powdered SAP using conventional coating methods ontotextile surfaces. For this purpose, water-based coating pastes containingmicronized SAP powder based on acrylamide/acrylic acid copolymer werecoated onto polyester (PES)-woven fabric surfaces using a knife-over-roll coat-ing technique. As the working parameters, the pH value of the coating paste,the coating thickness (the distance between the cloth and the knife), the dry-ing/fixing temperature and time, the SAP concentration, and the water absorp-tion capacity according to time were investigated. The results were evaluatedby applying the coating thickness, the amount of coating material transferredto the fabric on the SAP-coated samples, water absorbing capacity, and centrif-ugal water retention tests. The obtained results have demonstrated that textilesurfaces with high water absorption capacity (on average 200%–350%) can beachieved by coating hydrophobic fabric surfaces, such as PES, with SAP undersuitable conditions.
