In fact, there are many different tests for school uniforms, all of which are designed to effectively improve the quality of school uniforms，this inspection is usually carried out by the quality control personnel on the assembly line or by the team leader to confirm the quality before finishing and to facilitate timely modifications to the product. For school uniforms such as blazers, which have high quality requirements, quality checks and controls are also carried out on the components before they are combined. For example, an inspection and control should be done before connecting the front piece with the back piece after the process of pockets, provinces and splicing on the front piece is completed; the sleeves, collar and other parts should also be inspected before they are combined with the body; such inspection work can be done by the personnel of the combination process to prevent parts with quality problems from flowing into the combination processing process. With the addition of semi-finished product inspection and component quality control points, it may seem like a lot of wasted manpower and time is invested, but this will reduce the amount of rework and ensure quality, bearing in mind that the investment in time costs is very high.

Data analysis method: through the statistics of the quality of the failed products, analyse the main causes and improve the production process at a later stage with a purpose. If the size of the garment is generally large or small, the reasons for such problems should be analysed and improved in later production through methods such as sample size adjustment, fabric pre-shrinkage and garment size positioning. Data analysis provides data support for the quality improvement of enterprises, clothing enterprises need to sound data records of the inspection process, inspection is not only to find out the non-conforming products, and then rework, but also should do a good job for the later prevention of the corresponding data accumulation.
2, observation method: through the team leader or random observation of the inspection staff, found quality problems promptly pointed out, and told the operating personnel the correct method of operation and quality requirements. For new employees or this new product on line, such an inspection is essential to avoid processing more products that need to be reworked.
