    Sammanfattning : The textile industry is one of the largest industries in the world and it causes up to 10 % of the global greenhouse gas emissions. With large environmental issues of cotton- and oil-based textiles, other options are explored such as man-made fibers producing fibers like viscose and lyocell. LÄS MER

  3. 2. Fractionation of textile fibres from denim jeans

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Sammanfattning : The structure and composition of denim jeans is complex. In addition to cotton, which is the dominating type of textile fibre, there may be up to about 20 % synthetic fibres. The synthetic fibres are found in the sewing thread and in the elastic yarns that are used to make stretch denim jeans. LÄS MER

  4. 3. Aktivering av en dissolvingmassa med enzymer före en konventionell viskosprocess

    Uppsats för yrkesexamina på avancerad nivå, Fakulteten för teknik- och naturvetenskap
