1. Chemical modification of regenerated-cellulose films with determined patterns and different regeneration mediums to achieve superhydrophobic properties
Kandidat-uppsats, Mittuniversitetet/Institutionen för kemiteknikSammanfattning : In our modern society there is a need to find a material that is biodegradable to reduce the use of plastic for a greener society. By means of superhydrophobic surfaces there is a possibility to replace plastic with cellulose and use Alkyl Ketene Dimer (AKD) as a sizing agent to make the surface hydrophobic. LÄS MER
2. A novel and feasible material recycling technique for end-of-life textiles as All-Cellulose Composites (ACCs)
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Today’s consumption of textiles generates a large volume of textile waste. Therefore, it is needed to find solutions to re-use the textile waste rather recycling fibers into new fibers. Research using pre- and post-consumer textiles in composites is ongoing and an interesting direction. LÄS MER
3. 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
4. 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
5. 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.
