Optimisation of the Warp Yarn Tension on a Warp Knitting Machine
AUTEX Research Journal, Vol. 12, No2, June 2012 © AUTEX OPTIMISATION OF THE WARP YARN TENSION ON A WARP KNITTING MACHINE Vivienne Pohlen, Andreas Schnabel, Florian Neumann, Thomas Gries Institut für Textiltechnik der RWTH Aachen University, Germany Otto-Blumenthal-Str. 1, D-52074 Aachen, Phone: +49 (0)241 80 23462, Fax: +49 (0)241 80 22422, E-Mail: [email protected], [email protected] Abstract: Investigations (calculations) based on a warp yarn tension analysis on a warp knitting machine with multiaxial weft yarn insertion allow prospective reduced yarn tension differences in technical warp knits. From this a future opportunity is provided to substitute the subjective warp let-off adjustment by a model of tension control. The outcome of this is a higher reproducibility with associated increasing process reliability and rising product quality. Key words: Multiaxial fabric, non-crimp fabric (NCF), warp knitting machine, warp yarn tension, yarn tension control. Initial situation warp knitted glass or carbon fibre layers. These are made on warp knitting machines with multiaxial weft insertion. These Increasing political pressure is demanding that industry now enable the production of NCFs for different applications by always produces environmentally sound products. The adjusting several parameters. automobile sector is developing more powerful, lighter electric vehicles (e.g. Megacity Vehicle, MCV). The MCV of BMW in A detailed study regarding various adjustable parameters on cooperation with SGL Automotive Carbon Fibers is based upon such a machine has not occurred in previous works. A basis a composite construction of steel, aluminium, and CFRP for this is provided by warp tension studies on conventional (carbon fibre reinforced plastic) of 40% [1]. -

Formulating Equations for Warp Knitted Structures (Fabrics) Notations Design Area
Published by : International Journal of Engineering Research & Technology (IJERT) http://www.ijert.org ISSN: 2278-0181 Vol. 5 Issue 03, March-2016 Formulating Equations for Warp Knitted Structures (Fabrics) Notations Design Area Dereje Berihun Sitotaw Textile Engineering Ethiopian institute of Textile and Fashion Technology, Bahir Dar University, Bahir Dar, Ethiopia Abstract— this formula is developed to solve the problems In warp knitting the fabric is produced by the developments of repeated mistakes during the notations of warp knitted of lap instead of loop in weft knitting for it is formed by structures. Notation of warp knitted fabrics is not easy lapping movement of warp yarn guide. The lappings are two like that of weft knitted fabrics. The degree of shifting, types depending of the movement of guide bar with yarn design areas, numbers of overlaps are the main things relative to needle surface and termed as overlap and considered during warp knitted fabrics designing. The underlap. Overlap is the lateral movement of the guide bars formula was developed by considering degree of wale on the beard or hook side of the needle. This movement is shift and number of overlaps in one line in the knitted normally restricted to one needle space. Underlap is the fabrics/structure. The formula will help warp knit lateral movement of the guide bars on the side of the needle designers particularly for those designing without remote from the hook or beard. This movement is limited software. The formulation was done by analyzing only by the mechanical considerations. It is the connection different types of warp knit structures. -

19. Principles of Yarn Requirements for Knitting
19. Principles of Yarn Requirements for Knitting Errol Wood Learning objectives On completion of this lecture you should be able to: • Describe the general methods of forming textile fabrics; • Outline the fibre and yarn requirements for machine knitwear • Describe the steps in manufacturing and preparing yarn for knitting Key terms and concepts Weft knitting, warp knitting, fibres, fibre diameter, worsted system, yarn count, steaming, clearing, winding, lubrication, needle loop, sinker loop, courses, wales, latch needle, bearded needle Introduction Knitting as a method of converting yarn into fabric begins with the bending of the yarn into either weft or warp loops. These loops are then intermeshed with other loops of the same open or closed configuration in either a horizontal or vertical direction. These directions correspond respectively to the two basic forms of knitting technology – weft and warp knitting. In recent decades few sectors of the textile industry have grown as rapidly as the machine knitting industry. Advances in knitting technologies and fibres have led to a diverse range of products on the market, from high quality apparel to industrial textiles. The knitting industry can be divided into four groups – fully fashioned, flat knitting, circular knitting and warp knitting. Within the wool industry both fully fashioned and flat knitting are widely used. Circular knitting is limited to certain markets and warp knitting is seldom used for wool. This lecture covers the fibre and yarn requirements for knitting, and explains the formation of knitted structures. A number of texts are useful as general references for this lecture; (Wignall, 1964), (Gohl and Vilensky, 1985) and (Spencer, 1986). -
