1. Biocomposite with Continuous Spun Cellulose Fibers
Master-uppsats, Luleå tekniska universitet/MaterialvetenskapSammanfattning : 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
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)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
3. En studie om regenererade cellulosafibrer som ett alternativ till bomull i trikåmaterial
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : 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.

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 matematikSammanfattning : 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. Production of Dialdehyde Cellulose and Periodate Regeneration: Towards feasible oxidation processes
Magister-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaperSammanfattning : 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
