  1. 1. 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.

  3. 2. Moisture Transport in PA6

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Emanuel Markström; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. LÄS MER

  4. 3. Quantification of Swelling in Sealing Materials

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Johanna Möller; Paula Erlandsson; [2021]
    Nyckelord :elastomer; rubber; gaskets; NBR; EPDM; swelling; diffusion coefficient; polymer technology; Technology and Engineering;

    Sammanfattning : The objective of this study was to quantify swelling in gasket materials to better predict the gaskets life span in heat exchangers. Alfa Laval produces plate heat exchangers, which are a common unit within the process industry. There are different types of plate heat exchangers, and one type is sealed with gaskets. LÄS MER

  5. 4. Characterization of the Electrical Resistivity and Water Sorption Properties of a Semiconducting Swelling Tape

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Maria Nicte Polanco Olsen; [2018]
    Nyckelord :;

    Sammanfattning : I närvaro av fukt och lokaliserade fältförbättringar kan vattenträd utvecklas inom polymerisoleringen av HV subsea kraftkablar. Vattenträd tenderar att växa obemärligt och försämra isolationsegenskaperna med tiden. Fuktigheten i isoleringen kan effektivt reduceras genom applicering av halvledande svällningsband. LÄS MER

  7. 5. Testing of micro-fluidic systems for Raman spectroscopic measurements on biological cells

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Malin Berger; [2018]
    Nyckelord :;

    Sammanfattning : Pulmonary Artery Hypertension (PAH) is a condition that can affect people as a consequence of infections or diseases such as lung disease, high blood pressure or pneumonia. When afflicted by these diseases, low oxygen content in the lung tissue causes the pulmonary arterial soft muscle cells (PASMC) located in the walls of the pulmonary arteries to chronically swell up.
