    Natural fibres are emerging as low cost, lightweight and environmentally superior alternatives to glass fibre in composites. Plant variety, climate conditions and extraction methods in the production of natural fibres introduce variabilities to fibre properties that are fundamentally important to the resultant composites. This paper presents an overview of the most commonly used natural fibres, their extraction, characterisation, treatments to improve fibre performance, textile processes to prepare preforms, composite manufacture and mechanical properties, and life cycle analysis. A particular emphasis is placed on fibre architecture, including the methods to manipulate fibre orientation in the preforms and the influences of preform characteristics on composite processes and product performances.

  • Design of Apparel Fabrics: Role of fibre, yarn and fabric parameters on its functional attributes

    The concept of design is not new for textile apparel products. Traditionally the designers have heavily relied on their intuition and experience. However, today′s consumer demands products with improved functionalities and quality. With the progress in science, new fibres, technology and finishing techniques traditional designing knowledge has become inadequate to fulfill the need of the consumers. A methodical approach to designing has become necessary. A systematic approach to the design of apparel fabrics and the role of fibre yarn and fabric parameters on functional attributes of the product has been discussed.

  • Recent and Traditional Approaches to Numerical Flow Analysis of Complex Fluids

    This article reviewed both traditional continuum-mechanics-based and recent micro-macro approaches to the flow analysis of complex fluids. The flow of viscoelastic fluids such as polymeric liquids was mainly treated. As for the continuum-mechanics-based approach, the development in numerical techniques for stabilizing the numerical scheme was introduced. As for the micro-macro approach, numerical simulations using the CONNFFESSIT approach and those based on the Fokker-Planck equation were reviewed. In addition, studies of micro-macro flow analyses of other complex fluids were briefly introduced.

  • Current State of Nanofiber Produced by Electrospinning and Prospects for Mass Production

    Melt electrospinning was able to achieve a thin fiber with nano-order diameter by controlling the amount of discharge. Biomaterial is one of the fields where nanofiber is actively studied. The challenge of Japan for application and mass production of nanofiber noticed at present is also explained in this paper. Hirose paper Co. Ltd. proposed the production technique for an electrospinning in bubbles which continuously arise in polymer solution by applying high voltage. In NEDO project of Japan, the productivity was improved by increasing number of nozzle and became 50 times as great as the previous one. In Shiga Prefecture, the manufacturing equipment was also developed.

  • Interlacing Process of Multiple Filament Yarn
    Yoshiyuki IEMOTO, Shuichi TANOUE
    2008 Volume 54 Issue 6 Pages 207-215
    Published: December 15, 2008

    In interlacing process, a multiple filament yarn, which runs in an air jet device called an interlacer, is hit by high-speed air jet and then, tangling parts and opening parts are made alternatively in the yarn axial direction. The yarn called an interlaced yarn is superior in post-processing because of cohesion. It is also made of yarns with different properties for specialty fabric. Almost half a century passed since interlacing process was born. It is almost established in a technical view point but much incomplete academically. This topic surveys the construction of interlaced yarn, measurement methods of yarn characteristics, interlacer characteristics, airflow in interlacers, yarn motion during interlacing process, and so on.
