1. 1. Optimering av en hydraulisk sprayfärgningsprocess med hjälp av förbehandlingar

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

   Författare :Asta Ovander; Saga Hallberg; [2023]
   Nyckelord :Hydraulic spray dyeing; wool dyeing; plasma technology; ultrasonic bath; sustainable preparation; resource efficient; Hydraulisk sprayfärgning; ullfärgning; plasmateknologi; ultraljudsbad; hållbar beredning; resurseffektiv;

   Sammanfattning : Textilindustrin har under de senaste åren vidtagit drastiska åtgärder för att ställa om till en mer hållbar industri och därav möta målen för Agenda 2030. Denna undersökning syftar till att förbättra den resurssnåla hydrauliska sprayteknikens infärgning på ullvävar med hjälp av två resurssnåla förbehandlingar, plasmateknologi och ultraljudsbad.

3. 2. 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.

   Sammanfattning : Background: As a company it is more important than ever to consider the environmental sustainability aspect within the whole supply chain and all the stakeholders. Studies show that people's concerns about environmental sustainability increases and will continue to grow in the future. LÄS MER

5. 4. Establishing a resource-efficient one-step process for dyeing and hydrophobic finishing of wool with a hydraulic spray atomising system.

   Master-uppsats,

   Författare :Roos Mulder; [2021]
   Nyckelord :Wool; continuous dyeing; reactive dyeing; acid dyeing; hydrophobic finishing; hyperbranched polymers; dendrimers; hydraulic spray atomising;

   Sammanfattning : The textile industry is a big environmental polluter, with one of the biggest concerns being water pollution and usage. This necessitates resource efficient methods for wet textile processes. LÄS MER

7. 5. More than meets the dye : a textile design exploration of combining fibre-specific dyeing and structural weaving to create a multidimensional fabric

   Kandidat-uppsats, Akademin för textil, teknik och ekonomi

   Författare :Saga Nilsson; [2015]
   Nyckelord :Textile design; textile fiber; weaving; dyeing; structure; material; sustainable design;

   Sammanfattning : This project explores the combination of a woven structure consisting of different fibers with dyeing to create a multidimensional woven textile capable of altering in expression. This project aims to show how a designer can work with fibre-specific dyeing and multiple fibers in a woven textile and the many possibilities this lends in a design process. LÄS MER
