According to investigations by authoritative organizations, formaldehyde, which has been identified as a class of carcinogens by the World Health Organization, has become the main pollutant in the newly renovated homes in China. More than 60% of the newly renovated households in the indoor environment have exceeded the national control standards. However, most consumers only know that formaldehyde comes from wood-based panels, laminate flooring or furniture used in home decoration, but they do not know the decorative fabrics, curtains and fabric furniture commonly used in interior decoration, which will also cause formaldehyde pollution in the indoor environment.
In order to control the harmful effects of harmful substances on textiles to people's health, from January 1, 2005, China officially implemented the mandatory national standard "National Textile Products Basic Safety Technical Specifications." The new "Specifications" require that five indicators of textiles circulating in the market must meet the standards, namely formaldehyde content, pH (pH), color fastness, odor and decomposable aromatic amine dyes.
According to the degree of contact between textile products and the human body and the special conditions of infants and young children, the textile products are classified into: Class A - baby products; Class B - products that directly contact the skin; Class C - products that are not directly in contact with the skin. The higher the security level, the stricter the corresponding standard value.
After the one-year transition period, if the spot check finds that there is a product that does not meet the standard, it is not only prohibited from selling, but also not allowed to be used as inventory or price cut, and can only be destroyed.
The safety quality of curtains currently on the market is too low? In response to the current situation that consumers often purchase in Curtain City, the newspaper “Consumer Life Lab†recently commissioned the China Indoor Decoration Association Indoor Environmental Monitoring Center to sell the Mujingyuan South Sanyuan Curtain City and Muxiyuan Longjiandu Curtain Fabric City. Some of the curtains were compared and the results showed that the formaldehyde content was within the national standard.
However, the experimenter pointed out that although no formaldehyde exceeded the standard, there were still 6 samples of formaldehyde detected a certain amount of formaldehyde. Moreover, the samples taken in this experiment are all samples that have been sold in the market and exposed to the air for a certain period of time, and formaldehyde is still found, which should attract the attention of consumers.
How to buy curtains, how to prevent formaldehyde, Song Guangsheng, director of the Indoor Environment Monitoring Center of China Interior Decoration Association, reminded consumers:
Pay attention when buying curtain fabrics: 1. Smell the smell. If the product emits a pungent odor, there may be formaldehyde residue, it is best not to buy; 2, pick flowers. When selecting colors, it is advisable to purchase light colors, so the risk of formaldehyde and dyeing fastness will be less; 3, look at the variety. Be cautious when purchasing fabrics and curtains that are anti-shrink, anti-wrinkle, soft, flat, etc., pay attention to whether the fabric label indicates formaldehyde content.
In addition, pay attention to the use: 1, the returned curtains should be fully soaked in water, washed to reduce the formaldehyde content remaining on the fabric; 2, some sheets, quilts and other textiles directly in contact with the skin also contain formaldehyde Must be used after washing. 3. If you have the condition, you can hang the curtain cloth in the outdoor ventilation place after washing, and then use it again.
4, if there are more windows in the room, you can choose curtains of different materials, such as blinds, roller blinds and so on. 5, you can also buy green plants such as spider plants, placed on the window sill can effectively absorb the formaldehyde released by curtains, etc., fully purify the air.
Consumption blacklist "killer" formaldehyde formaldehyde is extremely harmful to people's health, known as the free "killer."
If the skin is exposed to formaldehyde, it can cause an allergic reaction and itching; if it is directly stimulated to the eyes, it may cause inflammation and tears. Breathing air containing formaldehyde for a long time may also cause the following symptoms: inflammation of the nose and throat, insomnia, dizziness, loss of memory, etc.
However, these symptoms are actually relatively light. According to scientific research, formaldehyde has carcinogenic effects, which may lead to nasal cancer, lung cancer and brain cancer. In addition, different people have different sensitivity to formaldehyde, and children and the elderly have the weakest resistance.
Where does the formaldehyde in the textile come from?
According to experts from the Beijing Textile Supervision and Inspection Institute, due to the strong anti-corrosion ability of formaldehyde, in order to make the garments achieve anti-wrinkle, anti-shrinkage, flame retardant effects, or in order to maintain the durability of printing, dyeing and improve the hand, it is necessary to produce in textiles. Add formaldehyde to the additive. Most of the popular anti-wrinkle garments or non-iron shirts on the market use formaldehyde-containing auxiliaries, which may release formaldehyde when worn.
When the textile is exposed to the air for a long time, due to the volatility of formaldehyde, it will be continuously released and pollute the indoor environment. In particular, some residential houses now have large windows, such as floor-to-ceiling windows and viewing windows. They are decorated with a house of about 100 square meters. It costs $8,000 to buy curtain fabrics. This is why some homes pay special attention to the control of formaldehyde pollution, but after the renovation, they found that one of the reasons for excessive formaldehyde in the room.
It is also known that the main reason for the widespread use of formaldehyde is its low price, and it is unrealistic to completely eliminate the use of formaldehyde in the production process of textile products. Textile products can be safely used if they are used within a limited range and are scientifically treated to control the formaldehyde content within the specified range.
The trend of consumption wind vane is changing every year, so in the apparel industry, the home industry is no exception. Curtains are regarded as "business cards for living rooms". Experts in the industry have suggested that after the complicated design, the simple and succinct colors and fabrics will become the mainstream of future home textiles. From the deep and complex of the past to the bright and fresh white, almost all of the new home textiles now choose a large area of ​​white as the base color, in the main color, pink, pink, yellow, tender green The frequency of occurrence has increased significantly.
