  1. 1. Biocomposite with Continuous Spun Cellulose Fibers

    Master-uppsats, Luleå tekniska universitet/Materialvetenskap

    Författare :Rocio Nahir Pineda; [2020]
    Nyckelord :cellulose fibers; biocomposite; vacuum infusion process; film-stacking process; polylactic acid;

    Sammanfattning : The subject of this project is to study spun cellulose fibers made by Spinnova Oy inFinland. The fibers are spun using an environmentally friendly spinning process withoutuse of harsh chemicals. LÄS MER

  3. 2. Influence of level of cellulose oxidation and surface treatment on the adhesion between cellulose beads

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Rasmus Källgren; [2020]
    Nyckelord :Cellulose; Fibre; Surface Coating; Layer-by-Layer; Oxidation; Cellulosa; Fiber; Ytbehandling; Layer-by-Layer; Oxidation;

    Sammanfattning : With the growing impact of climate change on both political decisions and how companies develop their products, it is increasingly important to find environmentally friendly alternatives to fossil-based materials. One of the more interesting materials in this respect is cellulose, which is the world's most naturally occurring polymer and can be used in a variety of applications. LÄS MER

  4. 3. En studie om regenererade cellulosafibrer som ett alternativ till bomull i trikåmaterial

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Olivia Norberg Blixt; Maya Lindgren; [2019]
    Nyckelord :Cotton; Lyocell; Modal; Tencel; Cellulose; Regenerated fibers; Environmental impact; Fibre properties; Bomull; Lyocell; Modal; Tencel; Cellulosa; Regenatfibrer; Miljöpåverkan; Fiberegenskaper;

    Sammanfattning : Bomullsfibern har många fördelaktiga egenskaper som gör den allmänt omtyckt bland både konsumenter och producenter. Den vanligaste framställningen av fibern är konventionellt odlad bomull, men dessvärre har denna typ av framställningsprocess en negativ inverkan på miljön i form av hög kemikalieförbrukning och hög vattenanvändning.

  5. 4. Production of regenerated nanocomposite fibers based on cellulose and their use in all-cellulose composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Andrés García Vogel; [2017]
    Nyckelord :All-cellulose composites; regenerated cellulose nanocomposite fibers; halloysite nanotubes; cellulose nanocrystals; LiCl DMAc; bio based;

    Sammanfattning : Biobased all-cellulose composites (ACCs), in which the matrix and the reinforcement are made out of the same material, have gained a noticeable increased attention in recent years. Their successful application would solve the commonly faced challenges with natural fiber composites regarding their chemical antipathy between the hydrophilic fiber and the usually hydrophobic polymer matrix, while still keeping the advantages of being environmental friendly.

  7. 5. Production of Dialdehyde Cellulose and Periodate Regeneration: Towards feasible oxidation processes

    Magister-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Författare :Elisabeth Höglund; [2015]
    Nyckelord :Dialdehyde cellulose; periodate regeneration;

    Sammanfattning : Cellulose is an attractive raw material that has lately become more interesting thanks to its degradability and renewability and the environmental awareness of our society. With the intention to find new material properties and applications, studies on cellulose derivatization have increased. LÄS MER
