Fabric defects that may occur at different stages of woven terry fabric production requires quality control and classification of fabrics as first or second grade before sending to customer. In this study, before shipping of two different terry fabric orders, defects were detected by inspection of fabric rolls on a lighted control board by experienced experts. Number of the defects and dimensions of the defects seen during the inspection were noted on quality control charts. Detected defects were defined and scored according to different demerit point systems. In this way, the fabric rolls were classified according to the demerit point systems before being shipped to garment enterprises. Disputes can be avoided with classification made by a demerit point system on which manufacturer and the customer have agreed.

Bornozluk Kadife Kumaşların Hata Kontrolü ve Hata Puan Sistemlerine Göre Sınıflandırılması

Öz

Bornozluk dokuma kumaşlarda üretimin farklı aşamalarında oluşabilen kumaş hataları, kumaşların müşteriye gönderilmeden önce kontrol edilerek birinci veya ikinci kalite olarak sınıflandırılmasını gerektirmektedir. Bu çalışmada, iki farklı sipariş için üretilen bornozluk kadife kumaş yüklemeleri öncesi, ışıklı panoda deneyimli kalite kontrol elemanları tarafından kumaş toplarının hata kontrolü yapılmıştır. Kontrol sırasında görülen farklı hataların sayıları ve hata boyutları kalite kontrol kartlarına işlenmiştir. Tespit edilen hataların tanımları yapılmış ve kumaş hataları farklı hata puan sistemlerine göre puanlandırılmıştır. Bu sayede kumaş topları konfeksiyon işletmesine sevk edilmeden önce hata puan sistemlerine göre sınıflandırılmıştır. Üretici ve müşterinin üzerinde anlaşmaya vardığı bir hata puan sistemine göre yapılan sınıflandırma sayesinde anlaşmazlıkların önüne geçilebilecektir.
