2022-7-17

 
"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
(1) Warehouse environmental conditions: Whether the humidity, temperature, ventilation and other conditions are suitable for the storage of relevant raw materials, such as the warehouse for storing wool fabrics, it needs to have moisture-proof, moth-proof and other requirements.
(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.
(1)   Review content of the template
 
①Whether the number of large and small samples is complete and whether there are any omissions;
②Whether the writing marks (model number, specification, etc.) on the sample board are accurate and whether there are any omissions;
③Recheck the size specifications of each part of the model. If the shrinkage is included in the model, it is necessary to check whether the shrinkage is enough;
④ Whether the size and shape of the seams between the pieces of clothing are accurate and consistent, such as whether the dimensions of the side seams and shoulder seams of the front and rear pieces are consistent, and whether the sizes of the sleeves and the sleeves meet the requirements, etc.;
⑤ Whether the surface, lining and lining samples of the same specification match each other;
⑥ Whether the positioning marks (positioning holes, notches), darts, pleats, etc. are accurate, and whether there are any omissions;
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.
(2) Check the number of pieces per pack or bundle.
(3) Check whether the size of the garment piece is deformed.
(4) Check whether the process sheet and the sample clothing conform to each other.
(5) Check whether the parts that need to be combined are consistent.
(6) Check whether the accessories, lining and fabric match.
(7) Whether the operation requirements are clear, understandable and correct.
(2) Quality control in sewing processing

⑤ Whether the error of component size and semi-finished product size is within the tolerance range;
⑥ Whether the product is clean and free of oil stains, water stains, pulp spots, scratches, etc.
(3)   Setting of inspection points during sewing
 
The inspection in the sewing process is also called intermediate inspection. If the inspection points are set reasonably, not only can the labor for repairing be greatly reduced, but also the root cause of quality problems can be found early and the occurrence of substandard products can be controlled.
 
Different styles of clothing have different inspection point locations, please refer to the following points:
 
(1) For defects detected by inspection points, it should not be necessary to disassemble intact finished products for repairing defects.
(2) Inspection points should not be covered by subsequent processes.
(3) Reasonably allocate inspectors and provide appropriate workload
(4) Statistics of defective products
 
When the quality inspection of the in-process and semi-finished products in the sewing process is carried out, the inspection results should be recorded and counted, and fed back to the relevant personnel in time, so that the management and technical personnel can give necessary guidance to the employees who produce waste and defective products to control An increase in defective products.
 
E. lock nail, ironing quality control
