  • Design of Pattern Preparation System of Computerize Flat Knitting Machine
    Journal of Wuhan University of Technology, 2006
    Co-Authors: Jin Chang
    Abstract:

    To solve the problem of pattern preparation system of computerize Flat Knitting Machine,a new program for graphic editor system based on object-oriented and multi-layer concept was designed and realized.By building flexible mechanism of class management,the quick drawing of the five graphic layers in pattern preparation system was realized.By adopting simple and possible data structure,the system realized the NC codes complier for Knitting Machine control.And the detail of this system was discussed.

  • Selecting Needle Time and Software Realization of Computerized Flat Knitting Machine
    Journal of Wuhan University of Technology, 2006
    Co-Authors: Jin Chang
    Abstract:

    The needle selection technology is one of the key technologies of computerized Flat Knitting Machine.The theory of needle selection is analyzed.Suitable selector is selected by accounting the time of needle selection,which ensures the reliability of computerized Flat Knitting Machine.The software realization of this method is probed into,which affords reference for the research of the control system.

  • Compression property and air permeability of weft‐knitted spacer fabrics
    Journal of The Textile Institute, 2011
    Co-Authors: Yanping Liu
    Abstract:

    This paper presents an investigation of the compression properties and air permeability of weft‐knitted spacer fabrics. Twenty spacer fabrics were knitted on a computerized Flat Knitting Machine with different weft knit patterns, spacer yarns, and loop lengths (stitch cam settings). Their compression property and air permeability were tested with the Kawabata Evaluation System for Fabrics (KES‐F). The influences of different factors were discussed and compared. The results obtained provide some useful information for new spacer fabric development.

  • Q15-based Flat Knitting Machine′s needle position tracking algorithm
    Textile Research Journal, 2012
    Co-Authors: Zhang Jianyi
    Abstract:

    Having analyzed the two tracking methods of needle position of Flat Knitting Machine,a new algorithm principle of needle position tracking of Flat Knitting Machine is proposed,which is based on quadrature encoding signals feeding back from AC servo motor.The algorithm,based on Q15,is successfully applied to convert floating-point into fixed-point.The Q value is determined by statistical analysis.The real-time simulation and comparison of hardware is performed on the platform of the Flat Knitting Machine.The results indicate that the time consumption completing once computation of needle position tracking with Q15 is 141.05 ns,and computing efficiency increased by 65.43% as compared with the conventional algorithm.This algorithm can be applied to needle position tracking of other Knitting Machines,such as socks Knitting Machine,circular Knitting Machine,underwear Machine,etc.

  • Flat Knitting OF A LIGHT EMITTING TEXTILE WITH OPTICAL FIBRES
    Autex Research Journal, 2009
    Co-Authors: Linda Oscarsson, Elisabeth Jacobsen Heimdahl, Torbjörn Lundell, Joel Peterson
    Abstract:

    Knitted products have a flexibility that offers many attractive possibilities. Combined with technical fibres, this gives interesting and innovative possibilities. Many technical fibres and yarns has however properties such as high stiffness and brittleness which are difficult to process in the practice of weft Knitting. This paper is about the experimental product development of a light radiating textile lamp in which optical fibres are used as the only illumination source. The lampshade is produced on an electronic Flat Knitting Machine with special equipment suitable for the feeding of yarn with high stiffness. The work was divided in two parts: exploring the possibilities to knit the desired shape on one hand and experimenting about Knitting with optical fibres as a weft insertion on the other hand. The method is an inductive approach; a literature survey, information from suppliers of Knitting production equipment and experimental work on a Flat Knitting Machine at The Swedish School of Textiles, Boras, Sweden. Results show that the diamond shaped structure can be knitted in one piece with transparent monofilament yarns. Furthermore it also shows that difficulties occur when Knitting with stiff and brittle optical fibres therefore the paper ends with a discussion with suggestions of how to overcome these challenges.

  • Development of a diamond shaped light radiating textile - an experimental Flat Knitting process with optical fibres
    2008
    Co-Authors: Linda Oscarsson, Elisabeth Jacobsen Heimdahl, Torbjörn Lundell, Joel Peterson
    Abstract:

    This paper is about the experimental product development of a light radiating textile lamp in which optical fibres are used as the only illumination source. The assigning company is GloFab, a company located in Stockholm, which designs different kinds of light radiating textile products. The paper is based on the work of a research project which had an inductive approach; the project consisted of a literature survey and experimental work on a Flat Knitting Machine located in the Knitting laboratory at the Swedish School of Textiles, in Boras, Sweden. The aim with the research project was to explore the possibilities to produce a knitted lampshade integrating optical fibres, shaped as a diamond with a hexagon basis (see Figure 1). This was done on an electronic Flat Knitting Machine with special equipment suitable for the feeding of yarn with high stiffness. This is interesting for GloFab because it gives possibilities to industrialize the production process and by doing so reach a wider market. In a broader perspective it is relevant to study how new materials can be used in traditional textile processes. The product development consists of two parts: exploring the possibilities to knit the desired shape on one hand and experiments about Knitting with optical fibres as a weft insertion on the other hand.
