n a knitting- confection profile factory, any activity oriented toward evaluation, maintenance or improvement of products quality level is based on measuring and examining the product quality characteristics, in order to establish conformity to the quality specifications and/or naming the non-quality characteristics (establishing defects and fabrication deficiencies. We can consider non-quality as complementary to quality, although a definitive distinction cannot always be made between the two categories or states. Cutting holds a key role in insuring shape precision and pieces dimensions, determining the quality of the confection process, its structure and manual stages frequency. The quality of the cutting operation, appreciated through the precision and aspect of cut contours, existence and precision of markings, is directly reflected in the finite product’s quality, which entails knowledge of cutting instrument - fabric interactions. In compliance of the technological regime during the operations in the cutting room can determine: incorrect marking, spreading, sectioning or cutting. Non-quality of intermediate products obtained in the cutting department can be evaluated and controlled through defectologic control methods.The De – Ca – Re method (defect-cause-remedy correlation), applied in this paper, allows establishing the most important causes that generate defects, as well as preventive and corrective actions to eliminate these causes. This paper systematically presents the main defects that may occur during operations in the cutting room, causes that generate these defects, along with their preventive and corrective actions.
