  1. 1. Establishing a resource-efficient one-step process for dyeing and hydrophobic finishing of wool with a hydraulic spray atomising system.

    Master-uppsats,

    Författare :Roos Mulder; [2021]
    Nyckelord :Wool; continuous dyeing; reactive dyeing; acid dyeing; hydrophobic finishing; hyperbranched polymers; dendrimers; hydraulic spray atomising;

    Sammanfattning : The textile industry is a big environmental polluter, with one of the biggest concerns being water pollution and usage. This necessitates resource efficient methods for wet textile processes. LÄS MER

  3. 2. Polymer Directed Engineering of Novel Cellulose Network

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Christel Gradin; Adina Landström; Julia Szecsödy; [2021]
    Nyckelord :Hydrogel; Carboxylated CNF; TEMPO-oxidation; bis-MPA ammonium dendrimer; Polymer salt bridge; Rheology;

    Sammanfattning : This study investigated a CNF/dendrimer hydrogel and how different concentrations of the carboxylated CNF and bis-MPA ammonium dendrimer affected the hydrogels’ rheological properties. A third generation bis-MPA ammonium dendrimer was diffused into a dispersion of carboxylated cellulose nanofibrils. LÄS MER

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

    Kandidat-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :Denize Åkerblom; Erik Göranzon; [2014]
    Nyckelord :Water and oil repellent; treatments; water and oil repellency; DWR; DWOR; perfluorinated compounds; PFCs; perfluorooctanoic acid; PFOA; perfluorooctane sulfonates; PFOS; dendrimers; organic silicon; hydrocarbon; hydrocarbon; aliphatic polyurethane; textiles; outdoor clothing; performance; UV-radiation; Martindale; washing;

    Sammanfattning : BACKGROUND: Perfluorinated compounds (PFCs) have been used as durable water and oil repellent treatments in clothing for more than 50 years. The reason for its popularity is related to the chemical structure, which also makes these compounds persistent in the environment. LÄS MER
