Three Steps For Quality Control Of Shirts Production

To ensure shirt The quality of production must first be prepared before the production of all kinds of technical documents, distributed to the process, inspection, production and other departments and related workshops, and the processing needed technical documents, such as drawings, process cards, logo and other operators to meet directly, to ensure that operators in the processing process can easily use these technical documents. The more perfect the production preparation work is, the better the continuity and balance of the production process will be, and the quality improvement will have a good environmental condition.

Production preparation includes confirmation. cloth And the arrival time, quantity and quality of other accessories can be linked to the production plan. Key equipment (such as burying machine) and key jobs should be avoided as far as possible. Ensure the equipment in production is in good condition, meet the process requirements, and have the equipment repair plan. The right labor force should be arranged so that workers with high technology level can be arranged on key processes and key equipment. Inspectors and operators should have the necessary measuring tools, which should be within the validity period of the cycle verification.

Shirt production has to go through many processes. We call quality control points a key process to be controlled. These quality management points are the quality characteristics, key parts, weak links and leading factors that need to be controlled in the manufacturing site for a certain period of time and under certain conditions. It can be a quality characteristic of a product or part, such as the size of a shirt, or a key part or key process, such as the appearance of a button, collar and sleeves.

The quality point of the shirt is set as the right page table.

Shirt production quality Control should start from the following aspects.

One Cloth inspection

Cloth inspection is the first hurdle for shirts processing, and is also a crucial hurdle. Only qualified products can enter the next process. Some defects in cloth are difficult to eliminate during processing, and directly affect the quality of finished products, such as coarse and fine yarn, broken yarn, neps, holes, oil pollution, etc. Cloth inspection can be divided into the following contents.

(1) use a cloth inspecting machine under the standard light source light box to inspect every cloth, and mark the edges with defects. For the fabric with more defects or unacceptable defects, it should be used or returned to the supplier as appropriate.

(2) color difference test, comparing the color of the cloth, cloth and tail of the same cloth, and testing the color of each cloth with the color card.

(3) shrinkage rate, the shrinkage of cloth directly affects the stability of shirt size, and the fabric with excessive shrinkage is not conducive to the control of shirt size.

(4) check the quantity to ensure the output of the fabric and fulfill the order.

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

2. intermediate test

There are many forms of inspection. According to the order of the work process, it can be divided into purchase inspection, process inspection and finished product inspection. According to the inspection place, it can be divided into fixed inspection and flow test. According to the quantity of inspection, it can be divided into full test and sampling inspection. The intermediate inspection in the process of shirts is mainly based on the combination of process inspection and flow test, to prevent the occurrence of defects, such as seam type, seam distance and dimension, which do not conform to the production process conditions, so as to effectively prevent and control defective products.

(1) process inspection

Process inspection is in the process of inspection. Process inspection not only examines the processing quality of the process, but also examines the technological factors that affect the quality of the process. Its role is to prevent defective products from flowing into the next process and to prevent the production of large quantities of defective products. Process inspection can be divided into one way process inspection and several process inspection. By way of process inspection is more effective to ensure machining quality, but the workload of inspection is large. For shirts enterprises, there are usually several inspection procedures. The inspection points are mainly located in the key processes that are easy to fluctuate or have a greater impact on the quality of the finished products, or the procedures that can not be repaired by waste products, such as collar, sleeve and other combined processes, such as the opening of the button door and so on.

(2) Flow test

Flow test, also known as circuit inspection, is a test carried out by full-time inspectors to the operator's workplace. Through the circuit inspection, we can find unstable factors in the production process and correct them to prevent the occurrence of batches of defective products. At the same time, it is also convenient for full-time inspectors to guide operators.

During the inspection tour, the inspector inspected the quality of the semi finished products and finished products, the workmen performing the process, the arrangement of the points on the process control charts, and the segregation of the inferior products according to certain inspection routes and times.
In the process of sewing, when the semi-finished products are to be stitched, they should undergo intermediate checks by special personnel to ensure that the semi-finished products are qualified and prevent the defective products from flowing into the next process.

Three Finished product inspection

Finished product inspection, also known as final inspection, is a comprehensive inspection before the product is put into storage. This is a necessary measure to prevent unqualified products from leaving the factory. After the finished product inspection, the inspection department shall issue the certificate to the qualified product. In garment processing enterprises, the inspection of finished products is mainly focused on the inspection of the tail processes of clothing appearance, packaging methods and packaging materials.
