    DETERMINING THE WOVEN FABRIC DEFECTS BY IMPLEMENTING IMAGE COMPARISON METHODS
    (Ege Universitesi, 2013) Arikan, Cihat Okan; Kadoglu, Huseyin
    Various fabric defects may occur over the surface structure during the production or use of the woven fabrics. Detection of the defects over the surface of the fabric is one of the most important factors for assessing the quality of the fabric. Fault detection is generally made by the human eye and the inspection of the fabric is a very laborious operation. In order to simplify this operation, the computer-assisted image processing methods may be used. In such methods, fabric image is electronically captured by appropriate camera systems which provides a faster comparison and also eliminates the human perceptive biases. In this study, solid-colored woven fabrics were subjected to the several image processing methods in order to detect certain fabric defects.

    Developing an Intelligent Automation and Reporting System for Fabric Inspection Machines
    (Ege Univ, 2019) Arikan, Cihat Okan
    In textile companies, the detection of defects and unacceptable areas of fabrics at the quality control stage has great importance for apparel production, although it is also a post-manufacturing operation for weaving and knitting mills, today it is still mostly being carried out on the guidance of human perception and sensory abilities. Such quality control operations are based on the attendant employee's detection of the defects and the unacceptable areas by visual inspection and scanning the overall fabric structure which is being transported on a brightly illuminated straight plane. The detected defects during the scanning operation are recorded on the defect charts and these outcomes subsequently are subjected to the quality control supervisor's evaluation and thereafter, it is decided whether the related inspection reports would exemplify an appropriate fabric to be used in production or not. In this study, it is aimed to develop a new system which enables to integrate the empirical paperwork-based reports that are still being commonly utilized by the majority of the textile companies in to the contemporary technology and also allows to compare such reports with the previous ones when it is necessary. The proposed system development consists of a fabric inspection machine which is equipped with a PLC-controlled digital display or in other words an intelligent control, and a web based software that enables the controller to analyze the reports comprehensively and simultaneously those of produced by this system, The system, which renders paperwork reports obsolete, allows the reports to be viewed on computer screens as soon as the inspection was completed. This feature ensures that all of the fabric rolls within the same order, multiple batches or bundles to be displayed on a single screen. Thus, it permits to determine the usability of the fabric for the production via employing the four-points system which is one of the prevailing methods for quality control procedures in the industry. Consequently, it is aimed to achieve significant time and labor savings in textile companies via utilizing this new developed system.

    Geometric Structures in Textile Design Made with 3D Printing
    (Univ Ljubljani, Fac Natural Sci & Engineering, Dept Textiles, 2022) Arikan, Cihat Okan; Dogan, Samet; Muck, Deja
    3D printing is a well-known technology for producing 3D objects by depositing successive layers of material. Among its many applications, the fashion industry has taken advantage of this technology to revolutionize its brands. Due to the unique properties of textiles, such as comfort, flexibility, etc., attempts have been made to create textile- like structures. Structures with different geometries were designed and printed using different materials ranging from rigid to flexible. In this study, three different basic geometric structures were designed using the Blender program (a free open-source 3D modelling software). Each geometric structure was designed in two different sizes with smaller and larger basic structural elements. In this case, six different models were created. The aim of this study was to compare the textile-like surfaces of different basic geometric shapes produced with 3D printers. It also aimed to investigate the use of surfaces designed with basic geometric shapes in the textile-like material for fashion industries. In the production phase, the fused deposition modelling (FDM) process was chosen, and ABS and TPU materials were used. Various tests were performed, such as mass tests, and tensile and flexural strength tests on models with different basic geometric shapes and sizes. An examination of the test results showed that the different geometric shapes of the various basic structures and the different materials used have an overall effect on the final properties of the structures. It was concluded that the obtained results can be used as a reference and could be helpful for researchers in the use of 3D printers in the textile-like material and fashion material industries.
