  1. 1. Mechanical properties of flax fibers and their composites

    Författare :Edgars Sparnins; Kristofer Gamstedt; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flax fibers; natural fiber composites; mechanical properties; Time dependent behavior; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Flax fibers, along with a number of other natural fibers, are being considered as an environmentally friendlier alternative of synthetic fibers in fiber-reinforced polymer composites. A common feature of natural fibers is a much higher variability of mechanical properties. LÄS MER

  4. 3. Biochemical Study and Technical Applications of Fungal Pectinase

    Författare :Jing Zhang; Gunnar Johansson; Gunnar Henriksson; Jonas Hafrén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Pectin; pectinase; polygalacturonan; polygalacturonase; retting; flax; enzymatic retting; pre-incubation; discoloration; pulping; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Pectinases are a group of enzymes produced by bacteria, fungi, higher plants and animals. Pectinases can modify and degrade pectins, a class of heterogeneous and multifunctional polysaccharides present in middle lamellae and primary cell walls of plants. LÄS MER

  5. 4. Betulin-modified cellulosic textile fibers with improved water repellency, hydrophobicity and antibacterial properties

    Författare :Tianxiao Huang; Monica Ek; Mats Johansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; Betulin; Biorefinery; Cellulose; Grafting; Coating; Hydrophobicity; Textile; Water repellency; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Textiles made from natural sources, such as cotton and flax, have advantages over those made of synthetic fibers in terms of sustainability. Unlike major synthetic fibers that have a negative impact on the environment due to poor biodegradability, cotton cellulose is a renewable material. LÄS MER

  7. 5. Development of hierarchical cellulosic reinforcement for polymer composites

    Författare :Abdelghani Hajlane; Angelika Bachinger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Cellulose is an environmentally friendly material which is obtainable in vast quantities, since it is present in every plant. Cellulosic fibers are commercially found in two forms: natural (flax, hemp, cotton, sisal, wood, etc.) and regenerated cellulose fibers (RCF). LÄS MER
