Many consumers believe that fabric sofas are more prone to formaldehyde pollution and other issues, while leather sofas are relatively environmentally friendly. But experts pointed out that if the leather sofa is not properly purchased, there will also be pollution problems. When consumers buy sofas, they should not only pay attention to avoiding the pollution of the surface material of the sofa, but also pay attention to the hidden danger of the interior of the sofa.
It is understood that the pollution of leather sofas and fabric sofas is DMF (Dimethyl fumarate, dimethyl fumarate) pollution, benzene pollution and formaldehyde pollution, the main form of expression is odor.
Sofa pollution mainly comes from three levels. The first is the surface layer, that is, the leather of the leather sofa, the fabric of the fabric sofa, and the surface paint layer of the wooden sofa.
The second layer is the internal filling. Some sofas are filled with sponges of low quality and low environmental protection. After long-term use and accumulation, they form pollution.
The third is the frame structure of the sofa. Since this part is not easily seen inside, it becomes the biggest hidden danger of sofa pollution. Non-environmental panels often cause indoor pollution due to high formaldehyde content.
Because the fabric sofas and leather sofas on the market are rarely pure cotton, pure wool or pure leather, the main raw materials are mostly chemical fiber, cotton, linen, blended, artificial leather, etc. The chemical textiles of the category use industrial raw materials such as formaldehyde and DMF to achieve insect-proof, anti-mite and anti-mildew effects in printing and dyeing, embryo making, and insect-proof and mildew-proof treatment.
Therefore, industry experts remind consumers to know the material of the sofa when purchasing the sofa, recognize the advantages and disadvantages, and always clean it during use to avoid excessive accumulation of pollutants.
â– How to choose
Understand standards and avoid being fooled
Some bad manufacturers often take advantage of consumers' unfamiliarity with national standards. Consumers should understand some basic requirements and definitions of products according to national standards. For example, the leather sofas currently on the market are mainly leather sofas and leather sofas (semi-leather sofas). The national light industry industry standard (QB/T1952.1-99) stipulates that the whole leather sofa refers to the sofa covered with natural animal leather except the bottom of the sofa seat; the main part leather sofa refers to the sofa sitting surface, the backrest front and the backrest. Natural animal leather-covered sofas are used on the upper and the inside of the armrests and on the armrests.
Because the cost of the whole leather sofa is extremely high, and the actual use is of little significance, most of the leather sofas currently on the market are leather sofas for the main parts. Renovation of the first network reminder Although the imitation leather and leather feel are different, coupled with the manufacturer's hands and feet, intuitively difficult to distinguish, consumers can only rely on the introduction of the business to identify the leather sofa and the main parts of the leather sofa.
Contract information must be written
The ticket for purchasing the sofa should be complete. The name, specification, quantity, price, amount and material of the sofa must be indicated on the invoice and contract (if it is a leather sofa, it should be indicated whether it is full leather). Renovate the first network reminder to ask the merchant or the organizer for the product warranty card. Know the name, address, contact person, and telephone number of the organizer and manufacturer to find out the quality problems and contact them in time.

Remember to ventilate in autumn and winter
In winter, in order to dispel the cold, people habitually close the doors and windows in the home. The air is not circulated, and harmful gases are hard to be volatilized. Therefore, families that are not renovated soon need to keep indoors ventilated.
In addition, the model sofa is non-polluting, which does not mean that the sofa produced from the factory is 100% pollution-free. When Xinsha is sent into the home, it must be checked and opened for a period of time. Renovation of the first network to remind consumers if the taste continues to produce no cut, it is best to manage or return.
