Fabric quality inspection standards and methods are very important for clothing designers and manufacturers. The following are some common standards and methods for evaluating and inspecting fabric quality:
1. Fabric density: Check the density and yarn density of the fabric. A magnifying glass or a specific weft computer scanner can be used to detect the yarn count and fabric density of the fabric.
2. Strength and durability: Evaluate the strength and durability of the fabric through tensile testing. This can be tested using a universal testing machine to measure parameters such as strength, breaking point and elongation.
3. Wrinkle resistance: Use an iron to conduct a wrinkle resistance test, heat the iron to the appropriate temperature, and then iron the fabric for a period of time to observe whether it will Produces visible wrinkles.
4. Pilling: Use a friction tester to conduct a friction test on the fabric to evaluate the pilling of the fabric. During the test, you can choose different strengths and cycle times to observe whether the fabric will pill.
5. Color fastness: Use a color fastness tester to evaluate the color fastness of the fabric. Tests include dry rubbing, wet rubbing, washing, decolorization, lighting, etc. to evaluate the impact of one or more factors on the color of the fabric.
6. Antibacterial performance: Evaluate the antibacterial performance of the fabric through bacterial culture and antibacterial testing. Bacterial growth can be detected using specialized culture media and microbiological techniques.
In addition to the above methods, you can also conduct hand feel evaluation, weight test, dimensional stability test, etc., and choose the appropriate inspection according to different types of fabrics and application scenarios. method. In addition, quality requirements and test methods issued by industry standards and certification bodies are also important reference materials, such as the International Organization for Standardization (ISO), American Standards and Testing Society (ASTM), etc.
It should be noted that different types of fabrics may require different quality inspection methods based on their characteristics. Therefore, when evaluating and inspecting fabric quality, it is best to Reference relevant standards and guidance from professional bodies to ensure results are accurate and reliable.
