With the growth of material welfare and General culture have increased requirements for appearance and quality of garments. Clothes should be beautiful, comfortable and durable.
To achieve a high quality of clothing required strict control at all stages of production, starting from receipt of fabrics and their preparation for nesting and ending with the packing and transporting of finished products.
In the mass manufacture of clothing, apply the following types of control:
a) control of incoming factory fabrics and other materials - adhesive materials, fittings, etc.;
b) quality control in the preparatory and cutting plants;
C) quality control of work in progress on process stream;
g) quality control of finished garments.
The quality control of fabrics, arriving at the factory, is presented in the fifth section.
Quality control in the cutting room the shop is in the validation of manufacturing obmalloc, laying out fabric and cutting details. The quality of cut checking for special control patterns.
For manufacturing quality products in the process stream is the responsibility of the master, who monitors compliance with the technological discipline during the processing of the products and giving instructions to the workers.
Methods of processing of parts on process flows are set by current technical documentation ("Foundations of technology unit-by-unit treatment"), developed TSNIISHP given the experience of the advanced garment factories.
Great value for increase of responsibility of workers and craftsmen for the quality of products has a well-organized self-control, mutual control and rolling control.
When self-control and mutual control, each worker is obliged to check the quality of the previous operation and the detection of the defect to prevent the product for further processing.
After performing the operation the worker verifies that the processing specifications and, after making sure that the operation transmits the product for further processing.
A rolling control (installation operation) is entrusted to the worker of high qualification, which monitors the quality of performance of technological operations.
A list of installation operations, work quality verification of previous.operations with indication of time and methods of quality control are given in table. 15.

The quality of the finished garments to determine the grade verifies the worker of the technical control Department (OTK), establishing the conformity of the product standard, technical condition, technical specifications and the approved sample in appearance, size, materials used, finishing and fittings.
Quality control of garments is conducted by the methods specified in GOST 4103 - 63 "sewing".
Products are individually controlled, daylight natural light or artificial light by external examination from the side of the uppers and lining or the inside, measuring products in locations specified in the technical documentation for this product. Quality control of garments, suits and coats groups produce on mannequins of the appropriate size or model (men, women, children) of the Constitution, all other articles (dresses, underwear, trousers) - on the tables.
Finished garments should have a good look and fit on the figure or dummy and to match the required size, growth, and body type.
During the inspection of the product from the lining, or the inside check the processing quality of lining and insulation strip, cut (product no lining), matching the size of the lining and insulation strip to the size of the top products, the presence of fabric defects.
In the evaluation of manufacturing defects and vices of textile clothing items are divided into open and closed when worn. Non-public details include: the lower part of podborov, lower collar, codpiece, otcasek, the lining of the belt in the trousers, the lining of sleeves, the inner part of obrazek and Podzorov in the pockets, the inner part prasravana folds, etc.
the Grade of finished products is determined by comparison of test results with the requirements of the technical documentation to determine the grade of these products (standards, technical conditions, technical description).
On the finished garments can set two classes: first or second.
Labeling and packaging of garments is produced according to GOST 10581 - 68 "sewing".
