Garment Quality Control Full Version


"Garment Production Quality Management Control Specification" is a production management specification formulated according to the garment production process. It is a quality control that must be carried out from the planning stage of production to the entire process of bulk production. The system and process are checked in real time, and for each order of the company, there must be a final quality control report to ensure that the quality meets the requirements.
The company's quality control personnel will regularly visit the supplier during the production period to monitor and ensure that the supplier strictly implements the company's quality standards and requirements. Ability to inspect all garments and access all records at any time.
The main purpose of "Apparel Production Quality Management Control Specification" is not only to check out the percentage of defective products, but to point out possible problems and to be able to correct these problems as soon as possible in subsequent production.
Garment production quality management control specification
A. Inspection of raw and auxiliary materials
The raw and auxiliary materials of clothing are the basis of the finished clothing. Controlling the quality of the raw and auxiliary materials and preventing the unqualified raw and auxiliary materials from being put into production is the basis of quality control in the entire clothing production process.
(1) Inspection of raw and auxiliary materials before storage
(1) Whether the product number, product name, specification, pattern, color, etc. of the material are consistent with the storage notice and invoice.
(2) Whether the packaging of the material is in good condition and neat.
(3) Check the quantity, size and width of materials.
(4) Inspect the appearance and internal quality of the material.
(2) Inspection of the storage status of raw and auxiliary materials

(2) Whether the warehouse site is clean and the shelves are clean, so as not to contaminate or damage the materials.
(3) Whether the materials are stacked neatly and the signs are clear.
B. Review of technical documents
Technical files are the main factor affecting product quality and belong to the software part in production. Before the product is put into production, all technical documents must be strictly reviewed to ensure that they are correct.
(1) Review of production notices
Check and review the various technical indexes in the production notice to be issued to each workshop, such as whether the required specifications and colors are correct, whether there is a one-to-one correspondence between raw and auxiliary materials, etc. Released to production.
(2) Review of the sewing process sheet
Review and check the established sewing process standards to check whether there are any omissions and errors, such as: ① whether the stitching sequence of each part is reasonable and smooth, and whether the form and requirements of the seam pattern are correct; ② whether the operation rules and techniques of each part Whether the requirements are accurate and clear; ③Whether the special sewing requirements are clearly indicated.
(3) Review of sample quality
Garment samples are an indispensable technical basis in production processes such as marking, cutting and sewing. They play an important role in the technical documents of clothing. The review and management of the samples should be careful and careful.

⑦ Arrange the template according to the size and specifications, and observe whether the template jump is correct;
⑧Whether the warp yarn marks are correct and whether there are any omissions;
⑨ Whether the edge of the template is smooth and round, and whether the knife edge is straight.
When the review and verification are qualified, the verification seal shall be affixed along the edge of the template, and it shall be registered and issued for use.
(2) Storage of templates
①Classify and file various types of templates for easy search.
②Complete the registration of the stand-up card. The sample registration card should record the original number of the sample, the number of pieces, product name, model, specification series and storage location of the large and small samples.
③Place it reasonably to prevent the deformation of the model. If the model is placed on the shelf, the large model should be on the bottom, the small model should be on the top, and the shelves should be flat. For hanging storage, use splints as much as possible.
④ The samples are usually placed in a ventilated and dry place to prevent deformation due to moisture, and at the same time, avoid direct sunlight exposure and insect bites.
⑤ Strictly implement the sample collection procedures and precautions.
(2)   Templates drawn by computer are more convenient to save and recall, and at the same time can reduce the storage space of the templates, just pay attention to keep a few more backups of the template files to prevent the files from being lost.

D. the quality control in the sewing process
Sewing is the main link in the garment production process. It involves many processes, personnel and equipment. It is a department prone to quality problems and the focus of quality control. We require line processing. This ensures continuous and stable quality throughout the production process. Quality control personnel should supervise quality at the production site and at the end of the production line. Supervisors should inspect the production site frequently. Once a problem is found, production should be stopped immediately until the problem is identified and resolved before restarting production. If there is a problem, make a record. The machine should be maintained by a mechanic. All machines should be regularly inspected for maintenance. It is suggested that the supplier may establish a maintenance service contract with the machine manufacturer. The machine operator is responsible for ensuring that the machine operates properly. If there is a major machine failure, the mechanic or supervisor should be contacted immediately. Broken needles should be recorded. All broken needles should be recorded in the work log.
(1) Requirements before sewing
(1) When receiving the garment piece, check whether it conforms to the batch number, specification and style in the production notice.
