Do you think that excessive formaldehyde content will only occur during house decoration? NO! NO! NO! Excessive formaldehyde content may also occur when student schoolbags are customized. So, what is the cause of the excessive formaldehyde content in student school bags? Next, let’s learn more about it with Leimande bags!

　　The excessive formaldehyde content in schoolbags is mostly caused by the excessive formaldehyde content in schoolbag fabrics. At present, in order to reduce the weight of the school bag itself and improve the durability of the school bag, most school bags are still made of textile fabrics. In order to achieve the purpose of anti-wrinkle, anti-shrinkage, flame retardant of textiles, maintain the durability of printing and dyeing, and improve the hand feel of textiles, formaldehyde is often used as an auxiliary agent in the production process of textile fabrics. However, in order to reduce production costs, some unscrupulous merchants will use cheap additives with extremely high formaldehyde content to make fabrics, which will lead to excessive formaldehyde content in finished fabrics. If schoolbag manufacturers accidentally select or choose low-priced fabrics with excessive formaldehyde content to make schoolbags when customizing schoolbags, the finished schoolbags will inevitably have excessive formaldehyde content.

　　According to the provisions of GB 21027-2020 "General Safety Requirements for Student Products" issued by my country's State Administration for Market Regulation and the National Standardization Management Committee, the limit of harmful substances in fabrics and accessories used in schoolbags and pencil cases shall not exceed the following values:

　　1. The content of free formaldehyde should not exceed 300mg/kg.

　　2. Decomposable and harmful aromatic amine dyes are prohibited. The content of each harmful aromatic amine should not exceed 20mg/kg.

　　Needless to say, everyone knows the seriousness of the hazards of prolonged exposure to items with excessive formaldehyde content. Schoolbags are mainly used by primary and middle school students. Children of this age are in a critical period of growth and development, and their physical resistance is not as strong as that of adults. If they are exposed to schoolbags with excessive formaldehyde content for a long time, it may cause physical fatigue, poor mental state, skin rashes, etc. Symptoms such as allergies may lead to serious consequences such as cancer. Therefore, when selecting fabrics for student schoolbag customization, in order to further protect the health of students, the fabric selection must be green, environmentally friendly, non-toxic and harmless.

　　At present, the environmentally friendly fabrics sold by regular sellers on the market have relevant test reports. If the custom-made party cannot determine the environmental protection performance of the fabric, it can ask the school bag manufacturer or fabric supplier to produce relevant test reports to ensure the integrity of the fabric in an all-round way. Environmental performance.

　　Customized schoolbags for students, you get what you pay for, and ultra-low-priced schoolbag products are often accompanied by problems such as poor-quality raw material selection and reduced production processes. Therefore, here I also want to remind everyone that when customizing school bags, don't just focus on the low price of school bags, but ignore the quality and environmental performance of school bags.
