The safety and quality standards of fabrics mainly involve the following indicators:
1. Fabric composition: The composition of fabrics should be clearly marked, including fiber type and proportion. Common fibers include cotton, linen, silk, wool, artificial fibers, etc. Different fibers have different properties and uses, and consumers can choose the appropriate fabric according to their needs.
2. Color fastness: Color fastness is a measure of the dye fastness of fabrics, that is, whether the color of the fabric will fade under washing, friction, sweat and other factors. Stablize. Color fastness levels generally range from 1 to 5. Consumers can choose fabrics with higher color fastness to keep the color of the clothing from fading.
3. Printing fastness of printed fabrics: For printed fabrics, printing fastness refers to whether the printing is easy to fade or cross-dye under conditions such as washing and friction. . Printing fastness is also rated from 1 to 5, and consumers should pay attention to choosing fabrics with higher printing fastness.
4. pH value: The pH value of the fabric reflects its irritation to the skin, and should generally be controlled between 5.5 and 7. Fabrics with a pH value that is too high or too low may irritate the skin and cause discomfort.
5. Formaldehyde content: Formaldehyde is a commonly used textile processing agent and is harmful to the human body at a certain concentration. The formaldehyde content in fabrics should comply with national standards. Consumers can choose formaldehyde-free or low-formaldehyde fabrics.
6. Flame retardant properties: Fire is a common danger. Flame-retardant fabrics have good anti-combustion properties, which can effectively reduce the risk of fire hazards. harm. Consumers can choose fabrics with good flame retardant properties, especially in some special working environments, such as factories, laboratories, etc.
In addition to the above indicators, fabrics should also comply with relevant national and industry standards and regulations, such as national quality standards, national textile inspection levels and the European Union’s Oeko- Tex standard etc. When consumers purchase fabric products, they can check the relevant certificates or logos of the products to ensure that the fabrics meet safety and quality requirements. In addition, it is also recommended to choose a reputable supplier with reliable testing and certification capabilities.
