  1. 1. Development of waterborne and mild curing DWRs, formulated with fully bio-based substances

    University essay from KTH/Fiber- och polymerteknologi

    Author : Johannes R. S. van Overmeeren; [2020]
    Keywords : Durable water repellents; Bio-based; Biodegradable; Two-phase systems; Fluorine-free; Functional textile finishes; Vattenavvisning; Bio-baserad; Biologiskt nedbrytbar; Fluorkarbonfri; Funktionella textilbehandlingar;

    Abstract : ”Durable water repellents (DWR) är textilimpregneringar som bidrar med vattenavvisande egenskaper som håller länge på funktionella tyg. Tyvärr är dessa hydrofobiska ytbehandlingar vanligtvis en källa till skadliga och persistenta kemikalier och de även är producerade från fossilbaserade resurser. READ MORE

  3. 2. Enhancing the durability of fluorocarbon-free Durable Water Repellant (DWR) formulation

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Meron Solomon; [2017]
    Keywords : Hydrophobicity; textile coating; cross-linker; nanoparticles; surface roughness;

    Abstract : The focus of the project was to alter and optimize the water repellant textile coating formulations to reach enhanced durability. For this purpose, the project was approached with three methods. Firstly, bio-based components were implemented in the mother emulsion to act as surfactant and crosslinking agent and to provide hydrophobic properties. READ MORE

  4. 3. Greener Water Repellency? Feasible alternatives to fluoro chemicals for DWOR treatments on textiles

    University essay from Högskolan i Borås/Institutionen Textilhögskolan
