Shirt quality control fabric shrinkage

Quality control of shirt production should start from the following aspects.

1. Fabric inspection

Fabric inspection is a critical step in shirt processing. Only qualified products can enter the next process. Some defects in the fabric It is difficult to eliminate during processing and directly affects the quality of the finished product, such as thick and thin yarns, broken yarns, neps, holes, oil stains, etc. Fabric inspection can be divided into the following contents:

(1) Use a fabric inspection machine under a standard light source light box to inspect each piece of fabric for defects. Make a mark on the edge of the fabric. Fabrics with a large number of defects or fabrics with unacceptable defects should be used or returned to the supplier as appropriate.

(2) Color difference inspection, compare the colors of the beginning, middle and tail of the same piece of fabric, and use the color matching card to test the color of each piece of fabric.

(3) Shrinkage. The shrinkage of the fabric directly affects the stability of the shirt size. Fabrics with excessive shrinkage are not conducive to controlling the size of the shirt.

(4) Check the quantity of pieces to ensure the amount of fabric used for production and complete the order according to the quantity.

(5) Fabric structure inspection, check whether the tightness, thickness and density of the fabric meet the requirements.

2. Intermediate inspection

Inspection can take many forms. According to the order of the work process, it can be divided into incoming inspection, process inspection and finished product inspection. According to the inspection location, it can be divided into Fixed inspection and mobile inspection can be divided into full inspection and sampling inspection according to the inspection quantity. The intermediate inspection during shirt processing is mainly based on the inspection method that combines process inspection and flow inspection to prevent the occurrence of process defects such as seam type, seam distance, size, etc. that do not meet the production process conditions, so as to effectively prevent and Control defective products.

(1) Process inspection

Process inspection is an inspection during the processing . Process inspection not only checks the processing quality of the process, but also examines the process factors that affect the quality of the process. Its function is to prevent defective products from flowing into the next process and prevent the occurrence of a large number of defective products. Process inspection can be divided into process-by-process inspection and several-process inspection. Process-by-process inspection is more effective in ensuring processing quality, but the inspection workload is larger. For shirt companies, they generally use several process inspections. The inspection points are mainly located in key processes where the quality is prone to fluctuations or has a greater impact on the quality of the finished product, or processes where scrap products cannot be repaired, such as collars and sleeves. Semi-finished products must be inspected before the process of merging pieces and before opening the button door and other processes that cannot be repaired.

(2) Mobile inspection

Mobile inspection, also known as roving inspection, is a full-time An inspection conducted by an inspector at the operator’s workplace. Through patrol inspection, unstable factors in the production process can be discovered and corrected in time to prevent batches of defective products. It also facilitates full-time inspectors to provide guidance to operators.

During tour inspection, the inspector follows a certain inspection route and number of tours to check the quality of semi-finished products and finished products processed in the relevant processes, and the performance of the process by the operating workers. , check the arrangement of ideas on the process control chart and the isolation of scrap and defective products.

During the sewing process of shirts, whenever semi-finished products are to be sewn, they must be inspected by specialized personnel to ensure that the semi-finished products are qualified and to prevent inadvertent sewing. Good products flow into the next process.

3. Finished product inspection

Finished product inspection, also called final inspection, is a comprehensive inspection before the product is put into storage. This is a necessary measure to prevent substandard products from leaving the factory. After the finished product is inspected, the inspection department must issue a certificate of conformity to the qualified product. In clothing processing enterprises, the inspection of finished products mainly focuses on the inspection of tail processes such as clothing appearance, packaging methods, and packaging materials.
