  1. 1. Biobased and biodegradable binders for paper and nonwoven

    Författare :Maria Wennman; Mikael S. Hedenqvist; Anna Justina Svagan; Mårten Hellberg; Wim Thielemans; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte complex; binder; chitosan; carboxymethyl cellulose; citric acid; nonwoven; tensile strength; hydrophobicity; Polyelektrolytkomplex; bindemedel; kitosan; karboximetylcellulosa; citronsyra; nonwoven; dragstyrka; hydrofobicitet; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Nonwovens are textile-like materials with similarities close to paper. One significant sector where nonwovens are used is for single-use products such as wet wipes and hygiene products. With an increasing global population, the manufacturing and use of nonwovens have grown significantly. LÄS MER

  3. 2. The use of Textiles in an Acoustic Context

    Författare :Karl Tillberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; porous absorbers; knitted fabric; woven fabric; helmholtz absorbers; room acoustics; nonwoven material; classroom; acoustic textiles; resonance absorbers; panel absorbers;

    Sammanfattning : Working with textiles in an acoustic context gives enormous possibilities to combine the acoustic function of materials with the visual function (aesthetics). Depending on the material choice and the production techniques, textiles may for instance be flexible, stiff, airtight, have high density or high porosity. LÄS MER

  4. 3. Studies of Elastomer Matrix Flow Mechanisms in Nonwoven Reinforced Composites

    Författare :Mikael Epstein; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The general aim of this work was to develop a suitable technique for fabricating elastomer composites based on three-dimensional fibrous materials and to study the rheological behavior of matrix polymer in these structures with varied structural and fiber surface characteristics. A new type of mold was developed and tested for structural reaction injection molding (SRIM) of elastomer composites having polymer matrices made from a mixture of two components. LÄS MER

  5. 4. Nanopolysaccharide coatings for functional surfaces in water-treatment materials : From mechanisms to process scalability

    Författare :Andrea Aguilar Sánchez; Aji P. Mathew; Albert Mihranyan; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopolysaccharides; coating; water treatment; nanocellulose; nanochitin; antifouling; antibacterial; separation technologies; materialkemi; Materials Chemistry;

    Sammanfattning : In this thesis, materials from renewable resources were used to develop functionalized surfaces for water treatment. The work is thus inspired by, and contributes to, the United Nations sustainable goals of: (i) clean water and sanitation, (ii) climate action, (iii) responsible consumption and production, (iv) life below water, and (v) partnerships for the goals.
