How to ensure the quality of finished socks?
Ensuring the quality of finished socks is a multi-step process, from the selection of raw materials to the final packaging, each step is crucial. Here are some key measures to ensure the quality of finished socks:
1. Quality control of raw materials
The quality of socks depends first on the raw materials used. The purchased yarns, such as cotton, yarn, spandex, polyester, etc., must be of reliable quality. These raw materials need to go through steps such as washing, drying and finishing to ensure the cleanliness and softness of the yarn
2. Precise execution of textile processes
Textiles are the core of sock production, and yarns are woven into the basic structure of the socks through textile machines. This process needs to be adjusted according to the style and size of the socks to ensure that the density and elasticity of the weaving meet the requirements
3. Dyeing and shaping
The dyeing stage is a key step in adding color and beauty to socks. The yarn needs to be pre-treated before dyeing, such as bleaching, washing, etc., to ensure uniform dyeing. The shaping process ensures that the shape and size of the socks meet the design requirements
4. Cutting and sewing
Cutting is carried out on the knitted socks according to the style and size of the socks, while sewing includes steps such as sewing the sock toe, strengthening the sock sole and reinforcing the sock mouth to ensure the firmness and durability of the socks
5. Quality inspection
The quality inspection of socks is a key link to ensure quality. The inspection content includes appearance quality, size and size, materials and craftsmanship. In terms of appearance, the socks should be flat, smooth, and without obvious defects; the color should be uniform and the pattern should be clear; there should be no odor and meet the hygiene standards. In terms of size, the size of the socks should be consistent with the nominal size, and the error range should be within plus or minus 2%
6. Packaging and labeling
Finally, the socks need to be sorted and packaged, and the socks should be kept clean and protected during the packaging process. At the same time, the logo and trademark of the socks should be clearly identifiable without blurry or missing parts
7. Follow industry standards
Following relevant national and industry standards is the basis for ensuring the quality of socks. For example, China's standard FZ/T 73001-2016 "Socks" specifies the terms and definitions, classification, requirements, test methods, inspection rules, packaging, marking, transportation and storage of socks.
Through the above measures, sock manufacturers can ensure that the quality of finished socks is up to standard and meets the needs and expectations of consumers. This not only involves the physical quality of the product, but also the comfort, durability and aesthetic appearance of the product.
What are the specific items included in the quality inspection of finished socks?
The quality inspection of finished socks is a comprehensive process involving multiple items to ensure that the socks meet the standards in terms of appearance, function and safety. Here are some key inspection items:
1. Appearance quality inspection
Appearance quality inspection mainly checks whether there are obvious damage, impurities, stains and other problems on the surface of the socks. This includes whether the color of the socks is consistent, and whether there are color differences, holes, missing stitches, thread ends and stain adhesion.
2. Size inspection
Size inspection involves checking whether the size parameters such as length, width, elasticity, etc. of the socks meet the standard requirements. This ensures that the socks are of appropriate size and comfortable to wear.
3. Color fastness inspection
Color fastness inspection is to test whether the socks have sufficient durability and will not fade due to washing, friction, etc. This includes color fastness to washing, color fastness to rubbing, color fastness to dry cleaning, color fastness to water, etc.
4. Fabric composition inspection
Fabric composition inspection aims to detect whether the material composition of the socks meets the standard requirements and whether it contains harmful substances. This involves fiber fineness, fiber diameter, fiber linear density, filament yarn fineness, etc.
5. Clarity test
Clarity test focuses on whether there are microorganisms, dust and other contamination problems in the production process of socks
6. Strength test
Strength test evaluates whether the tensile strength and wear resistance of socks meet the standard requirements
7. Packaging test
Packaging test ensures that the packaging of socks is intact and meets the standard requirements
8. Sewing quality inspection
Sewing quality inspection involves checking whether the seams of the opening, toe, sole, heel, etc. of the socks are flat, whether the thread ends are finished, and whether the stitches are neat
9. Elasticity test
Elasticity test focuses on whether the elasticity of the sock opening, ankle and sole meets the requirements to ensure the comfort and wearing effect of the socks
10. Finished product inspection
Finished product inspection is a comprehensive inspection of the finished product to ensure that all processes have passed the quality inspection standards, including appearance inspection, product cleanliness inspection, tensile test, etc.
Through these detailed quality inspection items, the quality of the finished socks can be ensured to meet the needs and expectations of consumers, and also meet the relevant industry standards and regulatory requirements.
