TRANSCRIPT

  • Slide 1
  • 1 Nano Technology in Textile Application National Taipei Uiversity of Technology Professor: Syang-Peng Rwei Sept. 27, 2006
  • Slide 2
  • 2 Introduction Nano Material Definition: 1 100 nm, many Physical properties are affected such as melting temperature, conductivity, UV absorption. Nano powder, Nano Fiber and Nonwoven, or Nanopattern on membrane or bulk-surface.
  • Slide 3
  • 3 Share of production by end-uses Based on volume produced 2004
  • Slide 4
  • 4 Increasing customer demands Hydrophobic Hydrophilic Anti-bacterial Barrier/Breathability Antistatic Stretch Smart/Intelligent Flame retardancy UV-absorption Added value
  • Slide 5
  • 5 Nano technology in textile application (Powder) (Fiber) (Membrane) Macromolec ule (Sol-Gel) (Mems) Nanoprint, Biochip (measuring)
  • Slide 6
  • 6 Examples of functions imparted Within the bulk of fiber On the surface of fiber In the structure of yarns and fabrics In the coated/Laminated layer High modulus/strength Water repellency Permeability, strength Barrier/comfort
  • Slide 7
  • 7 The methods of producing nanofibers 1. Self-assembly 2. Bacteria Celluose 3. Nanofibers spinning --Conjugate spinning --Electro spinning --Produced nanofiber in polymerization --Molecule discotics spinning
  • Slide 8
  • 8 1. Self-assembly method Self-assembly method ( SAM) is nano material system regulation another essential method. At present still was the research trial scope, has not been able the commercial use. (Van der Waals) ( Molecular recognition) Forms the bigger special geometry shape the atom or the molecular unit polymer. Using the high polymer self- composition and the polymerization, at present the scientists can make most minor diameter 3nm nano level textile fiber.
  • Slide 9
  • 9 2. Bacteria Celluose Microorganism grows the textile fiber diameter using Asedobakuda Aseti approximately between the 20~50nm bacterium cellulose.(Nonwoven membrane) This textile fiber has crystal high modulus The use machine uses the cloth membrane to the acoustic loudspeaker gill. Chemical structure of Kadoran
  • Slide 10
  • 10 3.1 Nanofibers spinning Conjugate spinning Conjugate spinning produced S/I fiber At present in the laboratory has been able to make 1,100 islands 0.001d (approximately 100nm) microfiber S/I fiber
  • Slide 11
  • 11 3.2. Nanofibers spinning Electro spinning Drawing polymer in the electric field Latent applies to does nonweave primarily, like separation membrane, medical surgical dressing, light quality compound material and wisdom textile fiber and so on. Electro spinning model
  • Slide 12
  • 12 Nanofibers spinning Electro spinning ElectroSpun polyester fibers x3000
  • Slide 13
  • 13 3.3 Nanofibers spinning Produced nanofiber in polymerization This method may make the diameter is only 30~50nm, namely only approximately ordinary textile fiber diameter 1 crystal textile fiber. Utilizes to the compound material, the electronic installation, including the automobile part, the electronic installation, the rope, fishes the line and the sports facility.
  • Slide 14
  • 14 This PE fiber have higher strength PE fibers molecular weight is 10 time in general PE fiber PE nanofiber 3.3 Nanofibers spinning Produced nanofiber in polymerization
  • Slide 15

  • Slide 28
  • 28 Market potentials of nanotechnology relevant technical textiles in the year 2010 Protective Clothing 0.3 million tons Medical and Hygiene 2.4 million tons Sport and Leisurewear 1.4 million tons Transporatation 2.3 million tons Environmental protection 0.4 million tons Industrial applications 3.2 million tons Professional clothes 1.6 million tons
  • Slide 29
  • 29 Nanotechnolgy based market outlook The total fiber consumption of the seven market segments amounts to 11.6 million tons with an estimated product value of ca us 60 billion in the 2010. Assuming that in the year 2010, 20% of the these products will be made by using nanotechnology means that the estimated market value for these products that year will be ca US 12 billion.
