To control the production quality of shirt should start with the following aspects: 
1. Fabric Inspection
    Fabric inspection is the first and also crucial checkpoint when producing shirts. Only qualified products can be passed into next process. Some fabric defects are difficult to eliminate, which will directly affect the quality of finished product such as spun yarn, soft sides, nep, hole, oil stain, etc. Fabric inspection can be divided into the following details:
(1) Use the cloth inspecting machine to check each fabric under the standard illuminant lamphouse. Mark at the edge of the fabric if there are defects on that fabric. Judge to use or return these fabrics to supplier if there are many stains or unacceptable stains on the fabrics.
(2) Color difference inspection: compare the same fabric with the color in the beginning, middle and end. Use the color card to check every piece of fabric color.
(3) Shrinkage rate: shrinkage rate of fabric will directly affect the stability of shirt size. Oversize shrinkage rate is not so good for controlling the shirt size.
(4) Fabric amount inspection: guarantee the fabric amount and complete the order according to the amount required.
(5) Fabric structural inspection: check whether the tightness, thickness, density of fabrics meet the requirement or not.
2. Intermediate inspection
    There are many forms to inspect. According to the order of work process it can be divided into receiving inspection, process inspection and finished product inspection; according to the place of survey it can be divided into fixed inspection and flow inspection; according to the amount of inspection it can be divided into total inspection and sampling inspection. While the intermediate inspection of shirt processing mainly is combined with process inspection and flow inspection. Preventing the process defects such as seam type, seam distance and size which are not meet manufacturing technique. Prevent and control rejects effectively. 
(1) Process inspection
    Process inspection examines during the processing. Not only need they examine processing quality but also examine the factors which effects processing quality. The function is used to preventing rejects from producing and flowing into the next process. Process inspection can be divided into one by one step process inspection and several steps process inspection. One by one step process inspection can guarantee the processing quality while the workload is large. Shirt enterprises usually use several steps process inspection, and the checkpoints are mainly located in the critical process where the qualities are easy to fluctuate or there are big influences to end products qualities. Or there is a process which some rejects can not repair, like combined panels such as attach collar and attach cuff before process and unrepairable buttonholing before process, so semi-finished products must be inspected.
(2) Flow inspection
    Flow inspection is also known as cyclic detection. It is the inspection which exclusive surveyors check in the workplace. Through the cyclic detection, labile factors in the productive process can be timely found and corrected. Not only does it prevents the rejects but also convenient for exclusive surveyors to guide the handlers.
On the basis of the certain inspection way and cyclic times, when doing cyclic inspection, exclusive surveyors should check the quality of semi-finished product and finished product which related to process, the conditions which operator carries out, the conditions which ideas arranged in the process control chart and the conditions which waste defective products segregate.
When sewing the shirts, every time we sew the semi-finished shirts, those must be intermediately inspected by the specialized person to guarantee the semi-finished shirts are qualified and the rejects will not passing to the next process.
3. Inspection of finished product
Inspection of finished product is also known as the final inspection. It is a overall inspection before the products put in storage and it is the requisite measure to prevent the rejects leaving the factory. Inspection department issues the certification after inspect finished product. In clothing factories, the main inspections for finished product are end process inspections such as garment appearance, manner of packing, packing material, etc.
