  • Investigation of the quality properties of open-end spun recycled yarns made from blends of recycled fabric scrap wastes and virgin Polyester Fibre
    'Informa UK Limited', 2019
    Co-Authors: Gün, Ahu Demiröz, Öner Eren
    Abstract:

    Recycled Fibre obtained from fabric scrap wastes is characterized by its low quality properties in terms of inhomogeneous Fibre type and non-uniformly distributed short Fibre lengths, both of which negatively influences the production process and the quality of the recycled yarns made from it. One of the common ways to utilize recycled Fibre in yarn production is to blend it with virgin Fibres. In this research article, the quality properties of the open-end spun recycled yarns produced in different material and spinning parameters from blends of recycled fabric scrap wastes and virgin Polyester Fibres are investigated. As material and spinning parameters, yarn count, blend ratio, waste type, waste origin, twist coefficient and rotor diameter are selected and their effects on the quality properties of the recycled yarns are evaluated through statistical methods. Statistical results reveal that especially blend ratio, yarn count and twist coefficient significantly affect the quality properties. In general, incorporation of virgin Polyester Fibre to recycled Fibre tends to bring about improvement in yarn quality. © 2019, © 2019 The Textile Institute

  • Dimensional and physical properties of socks made from reclaimed Fibre
    'Informa UK Limited', 2014
    Co-Authors: Gün, Ahu Demiröz, Akturk H.n., Macit, Ayşe Şevkan, Alan Gonca
    Abstract:

    The purpose of this study is to compare the dimensional and physical properties of the socks made from the blend of reclaimed Fibre and virgin Polyester Fibre with the similar socks made from virgin cotton Fibre, together with the influence of incorporated elastane. The reclaimed Fibre socks exhibit higher stitch density, mass, thickness and pilling tendency and lower air permeability than the cotton socks. Abrasion behaviours of the socks are assessed by measuring the mass loss and colour values after abrasion cycles. The mass loss values of the reclaimed Fibre socks are found to be lower than those of the cotton socks after abrasion. Regarding the colour properties after abrasion, the reclaimed Fibre socks reveal higher colour strength (K/S) values and lower colour difference (?E*) values. From the colour values after abrasion, it can be concluded that the reclaimed Fibre socks lose their colour little less than the cotton socks. © 2014 © 2014 The Textile Institute.2013/TP005This work was financially supported by the Scientific Research Centre of Usak University [2013/TP005].

  • Perilaku Geser Tanah yang Distabilisasi dengan Abu Ampas Tebu-Semen dan Inklusi Serat Polyester
    Universitas Diponegoro, 2017
    Co-Authors: John Tri Hatmoko, Hendra Suryadharma
    Abstract:

    Bagasse ash is a fine residue collected from the burning of bagasse in sugar factory, and it behaves as pozzolanic materials. In addition, engineering behaviour of bagasse ash can be improved by addition of cement containing high calcium. Recently, research about cement stabilized soil is continuously in progress. In this paper, a set of experiment programs were done to investigate the randomly oriented Polyester Fibre  inclusion in bagasse ash-cement stabilized soil.  Bagasse ash was mixed with clay in different proportions. To get the optimum curing period,  it was done light compaction test of soil with 8% cement cured with 7, 14, 21, 28 and 36 days curing period,  that was found on 28 days. The next experiment was compaction test on soil + 8% cement + 3,6,9 and 12% bagasse ash to obtain optimum bagasse ash proportion. The result indicated that optimum bagasse ash content was 9%. To ensure this result, unconfined compression test was done on the same sample. Finally, light compaction, unconfined compression and direct shear tests were done on : soil + 8% cement + 9% bagasse ash +  Polyester Fibre with 28 days curing period. The results showed that maximum dry density and optimum moisture content was not influenced by Fibre inclusion, whereas the increase of shear strength of stabilized soil with Fibre inclusion  was mainly due to improvement of internal friction angle. In unconfined compression test, the unconfined compression strength of stabilized soil was significantly improved by Fibre inclusion
