All defects found in the garment, can be divided into three types. It textile defects, design defects and defects of processing. 
To textile defects include local tissue defects, ie, defects, common in a limited area (openings, flying duck, blizny, Nagasaki, thickening, etc.) and distributed across the surface of the fabric (color variation, contamination, streaking).
To defects in design treat the defects, causing poor fit man, discrepancy, or excessive length shelves the bottom one another, kinks or distortions on the backrest and shelves under the armhole, uneven the bottom line, etc.
But sometimes in the finished product defects designs difficult to distinguish from defects of processing. So, for example, from improper connection of side or shoulder cuts there may be such defects as the discrepancy between the shelves or down excessive entering them one upon the other, transverse creases on the sleeve due to changes in the size of the openings, and from incorrect connections sleeve with the armhole (improper distribution of planting) may be creases, distortions, etc.
The processing defects may occur: non-compliance with technical conditions; - compliance regimes the wet-heat treatment (tan, arson, Lasy and curvature figure); from careless handling in the workplace (sections, spots, etc.). 
Eliminate defects in the finished product is very difficult, much easier to correct defects on those operations on which they arose. In order to prevent the appearance of defects and increase the qualityproducts include:

1) the organization of socialist competition and the fight for the title and shock brigades of Communist labor; 

2) exchange of experiences and introduction of advanced methods and techniques of leaders and innovators; 

3) systematic instruction working on new models and new technologies;

4) the introduction of modern equipment and care; 

5) observance of industrial and technological discipline; 

6) the development of several working operations; 

7) promotion of production workers employed without marriage; 

8) involvement in the quality assurance of older experienced workers retired.
