Bilgisayar Destekli Yarı-Otomatik Tasarlanmış ve Geliştirilmiş Yerli Bir Numune Dokuma Makinesi

This project involves designing, improving and making a prototype with having computercontrolled shedding, weaving design and patterning as a new version of the semi-automated dobby sampling loom, manufactured by Gulas-Machine (Istanbul). A CAD-CAM program that can manage the shedding function of this machine, Woven Pattern Design Program, was developed with DELPHI XE5 version. The developed Woven Pattern Design Program, not only manage the machine functions but also it can be used for individual studies for the weaving patterns and production planning. This article represents technical information, functions and usage of the developed sampling loom

Geliştirilmiş Bir Yerli Dokuma Desen Tasarım Programı

In this study, a CAD-CAM program which can be used for individual studies for the weaving patterns and production planning, Weaving Pattern Design Program, was developed using DELPHI XE5 version. Drawing plans and dobby plans are produced manually or automatically with pattern design. Pattern design and development tools are used in program menu. The developed Woven Pattern Design Program also provides managing the shedding mechanism of a national sampling loom directly from the computer.

Effects of Weft Count and Weft Density on Yarn Crimp% of Unbleached And Bleached 3/1(S) Twill Woven Fabrics

In this study, the effects of weft yarn count and weft density on crimp% of unbleached and bleached 3/1(S) twill woven fabrics are investigated. The warp yarn properties (type, count and warp density) were kept constant while the effect of variation in weft count and weft density were studied. Crimp% of unbleached and bleached fabrics are calculated by dividing the difference between straightened yarn length and the distance between the ends of the yarn while in the fabric, by the distance between the ends of the yarn while in the fabric as percentage. It is observed that the crimp% of warp and weft yarn in woven fabric is effected by weft count and weft density statistically. Moreover weft and warp crimp% of bleached fabrics have higher values than unbleached fabrics as a result of the change in weft densities after bleaching process.

Investigation of Weaving Capability of a Computer Controlled and Semi-Automatic Sampling Loom

In this study weaving capability of a prototype sampling loom with having computer-controlled shedding, weaving design and patterning is investigated. First, preparation stage of prototype sampling loom with the selected weave types before weaving process is investigated comparing with the semi-automated punched-card sampling loom. To evaluate the weaving capability of the improved prototype loom samples were woven in selected weave types with weft yarns in three different yarn counts. The results of weaving periods and structural characteristics of the samples were investigated in terms of weave type and weft yarn count.

Bir Numune Dokuma Tezgahı için Tasarlanmış Alternatif Ağızlık Açma Mekanizmaları

Cerceveli endustriyel dokuma makinelerinde, her bir cozgu telinin gozlerinden gecirildigi gucu tellerini tasiyan cerceveleri yukari ve asagi yonde hareket ettirerek agizlik olusumunu gerceklestirmek icin armurlu ve kamli mekanizmalar kullanilmaktadir. Yuksek hizlarda calistirilmak uzere tasarlanmis olan bu mekanizmalar numune dokuma tezgahlari acisindan oldukca maliyetli olmaktadir. Bu calisma, bir numune dokuma tezgahinda armurlu desenlerin dokunmasi amaciyla tasarlanmis olan uc alternatif agizlik acma mekanizmasi hakkinda bilgi sunmaktadir.

Ev Tipi Yıkama ve Kurutma İşlemlerinin Denim Görünümlü Örme Kumaşların Kalınlık ve Hava Geçirgenlik Özelliklerine Etkisi

Denim gorunumlu orme kumaslardan uretilen giysiler kullanim sonrasinda yikandiginda, yapilan tekrarli yikamalar ve kurutmalardan dolayi cesitli fiziksel ozellik degisimlerine ugrayabilmekte ve bu degisimler kullanici memnuniyetini olumsuz etkileyebilecek bir durum olusturabilmektedir. Bu calismada ev tipi yikama ve kurutma islemlerinin denim gorunumlu orme kumasin kalinlik ve hava gecirgenligi uzerindeki etkileri incelenmistir. Gunluk hayatta yapilan yikama islemlerine benzerlik gostermesi icin kumaslar ev tipi camasir makinesinde yikama islemine tabi tutulmustur. Her yikamadan sonra kumaslarin bir kismi asilarak oda sicakliginda, bir kismi 40°C sicaklikta tamburlu kurutma makinesinde ve geri kalani 70°C sicaklikta tamburlu kurutma makinesinde kurutulmustur. Kumaslarin konfor ozelliklerini etkileyen parametrelerden kalinlik ve hava gecirgenligi ozellikleri test edilmis ve elde edilen sonuclar istatistiksel olarak incelenmistir.
