   Sammanfattning : Throughout history, the spread of microorganisms has caused much damage including infectious diseases and deaths. Ever since humans realized the impact of bacteria especially on population health many efforts have been done to combat the spread of pathogens. LÄS MER

3. 2. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide

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

   Författare :Ryoi Takamatsu; [2023]
   Nyckelord :Dyeing; supercritical carbon dioxide; indigo; cotton; eco-friendly; textile;

   Sammanfattning : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. LÄS MER

4. 3. 3D Knit fabrics : optimizing spacer knit fabrics for comfort and breathability in infant products

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

   Författare :Julia Svensson; Hanna Halldorf; [2023]
   Nyckelord :Spacer fabric; knitting; warp knit; circular knit; textile testing; ProCad Warpknit; infant product; comfort; mechanical properties.;

   Sammanfattning : In this study we looked into an existing textile baby stroller seat and investigated whether there can be any advantage in changing the material to a spacer fabric from perspectives such as functionality, comfort, and sustainability. The subject of 3D knitting, and advanced knitting is being researched more and more because of its versatility in producing and changing parameters of knitted high quality products, but there is a lack of studies done on comfort for children when it comes to knitted spacer fabrics and not many studies have been done on spacer fabrics used for baby seats in strollers or other types of seats for children.

5. 4. Impact of Organic Solvent Treatments on Physical and Sensorial Properties of Knitted Fabrics.

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

   Författare :Sara Isabel Zamora Lagos; [2023]
   Nyckelord :Innovation; Screen-printing; Knitted fabric; Polyester; Cotton; Organic Solvents; Cycle; Properties; Physical; Structure; Sensorial.;

   Sammanfattning : Technologies that facilitate reusing and recycling printed textile products will contribute to achieving a circular textile industry. This project was done in collaboration with Vividye, a company developing a technology to create removable textile prints to be able to extend the lifespan of screen-printed textile products without affecting their quality.

7. 5. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

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

   Författare :Elise Meurs; [2023]
   Nyckelord :Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

   Sammanfattning : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.
