  1. 1. Biocomposite with Continuous Spun Cellulose Fibers

    University essay from Luleå tekniska universitet/Materialvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Abstract : 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. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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.

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

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Author : Elisabeth Höglund; [2015]
    Keywords : Dialdehyde cellulose; periodate regeneration;

    Abstract : 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. READ MORE

  6. 5. Rheological study of cellulose dissolved in aqueous ZnCl2 : Regenerated cellulosic fibres for textile applications

    University essay from Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Louise Ulfstad; [2013]
    Keywords : Rheology; cellulose dissolution; ZnCl2;

    Abstract : The most known regenerated cellulosic fiber is viscose, produced in a wet spinning process, but due to cost and environmental issues other processes have been developed. Lyocell fibers, produced in air-gap spinning, have superior dry and wet strenght and a lower environmental impact compared to viscose. READ MORE
