  • Textile is unique among classes of man-made materials

  • Textile and textile community creates problem

    Textile and textile processing provides solutions

  • If textiles did not exist

  • If textiles did not existAll humans wear textiles: 100% market coverage

    There has been no culture ever not having textiles

    Textiles is ever present 24-7 in human life: 20 min 1.39 % is textileless

    Textiles is ever present 24-7 in human life: 20 min 1.39 % is textileless

    Create 2D surfaces - cheap and with precision

    Obtain lightweight materials

    2D continuity Cover large and small

    objects (mm)2 to (km)2

    Interfaces Drape Create flexible function Handle (1D) strength Create distance Create porous layers Create dense layer Express aesthetics Patterns - periodic Create high tensile

    strength Keep moisture

  • I. Textile is the class of material closest to humans

  • Technosphere synthetic, artificial,

    man-made realm System Functions Artefacts

    Biosphere the totality of

    biological matter system functions biofacts

  • Characteristics of biofacts and nature as a manufacturer

    The way technology address these items

    Biological materials are made from one or both of two polymers: proteins (poly(amino acids)) and polysaccharides (polymers mostly of six-carbon sugars or hexoses).

    For plastic a very large number of polymers have been synthesis showing a wide spectrum of properties. Besides metal and metal alloys, ceramics, glass are used

    Fluxes of energy, info and materials Fluxes of energy, info and materialsWaterbased chemistry Water is used in industrial processes but also a

    spectrum of hazardous solventsStructures are often hierarchical Sometimes hierarchicalSelf-assembly Top-down such as drilling, cutting, sawing -

    subtractive manufacturingBottom up Top-down Rounded surfaces Typical sharp, square, surfaces; trianglesFlexibility, pliability Rigid, hardSoft matter (exceptions include teeth) Hard (metals, synthetic diamonds and alike)Adaption (sometimes tropism, or on long term : migration)

    Artefacts are dead, just recently smart materials have appeared
