1. What does the quality inspection of clothing products include?

The details are as follows: (1) Material library inspection.

The materials used by garment enterprises include fabrics, accessories and machine materials. The main purpose is to inspect the fabrics, such as length, width, weft skew, color difference, defects, shrinkage, etc. Except for the inspection of linings and fabrics, other accessories are generally inspected at the time of purchase.

The inspection method for machine materials is the same as that for auxiliary materials. Fabric inspection generally adopts sampling inspection. The sampling ratio mainly considers the cost of the fabric. Usually, the higher the cost of the fabric, the greater the sampling ratio.

For general cotton, cotton-type fabrics, and chemical fiber fabrics, 10% can be selected for random inspection, while high-end woolen and silk fabrics must be fully inspected. (2) Sample inspection.

Samples are the most important technical documents and standards in garment factory production. There are three types of clothing enterprise templates: benchmark board, production board and auxiliary board.

The benchmark board is the basis for verifying other boards and is for archiving purposes. Generally, only the intermediate files are taken. The production board is used for layout and pattern making in the cutting workshop. It is a rough board added on the basis of the reference board.

The auxiliary board is a clean board for small parts or parts of garments to facilitate operation and quality control. There is a lot of content to review the sample, and different products have different requirements. The sample should be reviewed in detail and comprehensively based on different clothing styles and customer requirements, especially the parts with strict specifications and sizes.

(3) Cutting inspection. The paving inspection mainly checks the number of paving layers, the front and back sides, and the accuracy of the three aspects (starting hand, lowering hand, edge of the fabric, and length).

The cutting inspection mainly tests the range and degree of the skewness of the silk strands. Generally, different garments and different parts have different requirements for the skewness of the silk strands. Inspect the pieces and use templates to check whether the specifications and curves, straight lines and arcs of the cut pieces are consistent with the standards.

Different cutting pieces have different error ranges, and the cutting pieces should also undergo upper and lower layer inspection and defective piece inspection. (4) Semi-finished product inspection.

Refers to the inspection of each component and assembly before garment sewing. The purpose is to identify quality problems early, reduce future repairs, and save cost and time.

(5) Specification inspection. Use a tape measure to measure each part of the garment according to certain measurement methods and procedures, and compare it with the specifications and standards to see if it meets the regulations.

General garment specification tolerance requirements are between ±5% ~ ±2%.

The significance of quality testing is to conduct compliance evaluation through observation and judgment, appropriately combined with measurement and testing. (1) For products, it refers to observing raw materials, intermediate products, and finished products according to product standards or testing procedures, conducting measurements or tests when appropriate, and comparing all obtained characteristic values ??to determine individual items or batches of products. Qualified and unqualified technical inspection activities.

(2) Quality inspection is to observe one or more quality characteristics of the product. Technical inspection activities that measure, test, and compare the results with specified quality requirements to determine the compliance of each quality characteristic.

2. Basic points of quality inspection (1) In order to meet customer requirements or expected use requirements and the mandatory provisions of government laws and regulations, a product must have its technical performance.

Various requirements such as safety performance, interchangeability, environmental and personal safety, and health impact are stipulated. These regulations constitute the corresponding quality characteristics of the product.

Different products will have different quality characteristics requirements. The same product has different uses and its quality characteristics requirements will also be different accordingly.

(2) Product quality characteristics requirements are generally converted into specific technical requirements in product technical standards (national standards, industry standards, enterprise standards) and other related product design drawings, operating documents or inspections It is clearly stipulated in the regulations and becomes the technical basis for quality inspection and the basis for comparing inspection results after inspection. After comparison, it is determined whether each quality characteristic tested meets the requirements specified in the standards and documents.

Product suitability is an important quality characteristic. (3) Product quality characteristics are formed during the product realization process and are determined by the quality of the product’s raw materials and various components (such as parts) that constitute the product, and are related to the professional technology, personnel level, and equipment capabilities of the product realization process. Even environmental conditions are closely related.

Therefore, it is not only necessary to provide skills training and qualified personnel for process operations (operators), but also to verify equipment capabilities, monitor the environment, and clearly define operations and process methods. When necessary, monitor operations and process parameters.

In addition, quality inspection of products is also required to determine the quality status of the products. (4) Quality inspection is to observe, measure, and test one or more quality characteristics of a product through physical, chemical, and other scientific and technical means and methods to obtain objective evidence that confirms product quality.

Therefore, it is necessary to have suitable testing methods (including various measuring and testing instruments, instrumentation, test equipment, etc.) and to implement effective control to maintain the accuracy, precision and consistency required for testing. sex. (5) The results of the quality inspection must be compared according to the product technical standards and relevant product drawings, process (process) documents or inspection procedures to determine whether each quality characteristic is qualified (conformity), so as to evaluate the single piece (item) The quality of crystals or batches of products is judged.

(6) Quality inspection should provide a correct and reliable basis for judging product quality compliance and applicability and making major decisions on product quality. This requires ensuring that the product quality inspection results are correct and accurate. 3.

The main functions of quality inspection (1) The identification function uses corresponding detection and inspection methods to observe, test and measure according to technical standards, product drawings, operating (process) procedures or ordering contracts and technical agreements. The quality characteristics of the product are used to determine whether the product quality meets the specified requirements. This is the identification function of quality inspection. (2) The "checking" function is to check the "gateway" for non-conforming products found in identification and not delivered for expected use.

(3) Prevention function ① Plays a preventive role through the measurement of process (process) capabilities and the use of control charts; ② Plays a preventive role through the first inspection and inspection of process (process) operations; ③ Generalized prevention effect. (4) Reporting function In order to enable the relevant management departments to timely grasp the quality status of the product realization process, evaluate and analyze the effectiveness of quality control, the data and information obtained from the inspection are summarized, sorted and analyzed into a report, which serves as the basis for quality It provides important information and basis for control, quality improvement, quality assessment, quality supervision and management to make quality decisions.

4. Steps of quality inspection (1) Preparation for inspection.

Be familiar with the requirements, select inspection methods, and formulate inspection specifications. In the preparation stage for inspection, if necessary, the inspection personnel should be trained and assessed on relevant knowledge and skills to confirm whether they can meet the needs of the inspection work.

(2) Obtain the samples for testing. The sample is the object of testing, and the quality characteristics exist objectively in the sample. After excluding the influence of other factors, it can be said that the sample objectively determines the test results.

There are two main ways to obtain samples: one is to send samples, and the other is to take samples. (3) Preparation of samples and specimens.

(4) Measurement or testing. According to the established inspection methods and plans, quantitative or qualitative observation, measurement, and testing of product quality characteristics are carried out to obtain the required values ??and results.

Before and after measurement and testing, inspectors must confirm that the inspection equipment and samples of the inspected items are in normal condition to ensure that the measurement and test data are correct and effective. (5) Record and describe.

Record or describe the measurement conditions, measured quantities and observed technical status in standardized forms and requirements, and save them as objective quality evidence.

(6) Comparison and judgment.

Full-time personnel will compare the inspection results with the specified requirements to determine whether each quality characteristic meets the specified requirements, thereby determining whether the inspected product is qualified. (7) Confirmation and disposal.

Relevant inspection personnel shall sign and confirm the inspection records and judgment results. Determine whether the product (single piece or batch) can be "received" and "released".

5. Concept of Product Validation Validation is the determination that specified requirements have been met through the provision of objective evidence.

It is a management inspection activity. 6.

Monitoring Monitoring is about something.

3. The significance of clothing quality inspection

The significance of clothing quality inspection 1. The connotation of quality (Quality): Quality is related to products and processes meeting regulations or potential needs. Characteristics, or the sum of them, are also a yardstick used to measure durability, comfort, and intended use.

Clothing quality requires our clothes to be in terms of the characteristics of the fabric, such as shrinkage, color fixation, or the various processes in the production process, such as uniformity and symmetry, as well as the accuracy of the dimensions of each part, and the surface of the clothes. Decoration, packaging, etc. must comply with customer requirements and regulations. 2. The status of quality in the corporate world. The quality of products (tangible or intangible) is one of the image manifestations of the company; the company's actions center on quality, and creating good quality products is a goal of the company's actions: Quality is what drives the company source of power for development.

3. The meaning of QC: QC is the abbreviation of English QUALITY CONTROL, and the Chinese meaning is quality control. It contains two meanings: one is quality inspection, and the other is feedback confidence and taking preventive measures. It is a working technology that meets the standards specified in the school, can adapt to market changes, can detect problems through inspection, and analyze the causes of problems. , so as to take measures to deal with it.

4. Responsibilities of the quality department: A. Participate in the incoming inspection of purchased product raw materials B. Assist in customer satisfaction measurement C. Responsible for product measurement and monitoring, make corresponding records and analyze them D. Responsible for the process Measure and monitor and make corresponding records E. Control of non-conforming products F. Implement continuous improvement.

4. There is a problem with the quality of the garment factory

Dear leader:

Hello! I have deeply realized my mistakes.

My mistakes came from my weak consciousness and ideological paralysis. To be precise, I was not serious enough, which led to this incident. I sincerely apologize for the losses that my mistakes have caused to the company.

Because I did not work seriously, I tasted the bitter fruits I sown and was also implicated. The company has suffered serious economic and reputational damage, which cannot be compensated with money. However, I am responsible for the cause, and I am willing to take responsibility. I cannot bring obvious benefits to the company with my own strength, but Everyone plays an important role in this group. I now understand that one person’s power is small, but the accident caused by one person’s lack of seriousness is significant. Because I didn’t have enough awareness and did things carelessly before, in the future I will I will do everything I do at work seriously, fulfill my due responsibilities, and contribute my strength to the company.

Through this incident, I deeply understood the meaning of "safety comes from vigilance, and accidents lead to paralysis". I deeply reviewed myself. Although this incident was not a safety accident, it was also caused by my own paralysis. ; I am willing to accept the punishment from the leader for causing this incident! At the same time, I am deeply determined to be more rigorous, serious about love, based on my position, dedicated to my job, and make my due contribution to the company's bright future! !
