Listen and feel four points to teach you the quality of bedding
Pay attention to health risks
According to the monitoring results of the Beijing Municipal Administration of Industry and Commerce, some bedding products exceeded the standard in terms of dye fastness, washing dimensional change rate and pH value. What do these indicators mean? What unqualified beddings can lead to safety hazards?
Wang Baojun, director of the National Textile Products Quality Supervision and Inspection Center, said that the pH value, formaldehyde content exceeding the standard and azo dyes in the bedding products pose a safety hazard to human health. He explained that if the PH value on the bedding is too high or too low, it will cause irritation to the skin and easily cause the skin to be attacked by other bacteria.
The azo dye that decomposes the aromatic amine is the most harmful to the human body. It is understood that after the use of azo dyes containing carcinogenic aromatic amines in textiles, in long-term contact with the human body, the dye may be absorbed by the skin and spread in the human body. Under the biochemical reaction conditions of normal metabolism of the human body, these dyes may undergo a reduction reaction to decompose the carcinogenic aromatic amine, and activate the DNA structure of the human body to cause human pathological changes and induce cancer.
In addition, if the formaldehyde content exceeds the standard, since formaldehyde is easily volatilized in the air, the formaldehyde remaining on the textile is gradually released into the air. For example, bedding and curtains are released indoors under natural conditions. Because formaldehyde is easily soluble in water, wearing clothes containing formaldehyde, combined with human sweat or hydrolysis to produce free formaldehyde, through the human body breathing and skin contact on the respiratory mucosa, eyes and skin, strong stimulation, causing respiratory inflammation and skin inflammation.
Inspect the quality of use
After reviewing the information, the reporter found that the color fastness and the change rate of the washing size were unqualified items that often appeared in several monitoring by the Industry and Commerce Bureau. These directly affect the quality of the bedding and the later use.
The color fastness is mainly used to evaluate whether the bed is faded after use or washing, and whether it will be contaminated with clothes. The relevant standards stipulate that the color fastness is rated on the 5th grade and the 9th grade, the highest grade is 5, and the general standard is about 3 grade. If the actual dyeing fastness of the commodity is only 1-2 grade, it will seriously affect the actual use of the garment.
Whether the clothes and bedding are shrinking or not is determined by the dimensional change rate of the washing. It is an indicator for measuring the degree of change in the outer dimensions of bed products after washing under the conditions stipulated by national standards. If this item is unqualified, it is easy to change the original size after washing with bedding products, etc., and we often say that shrinkage, deformation, etc., affect the use.
In quality monitoring, odor is also one of the must-check items. Wang Baojun explained that in the production process of bedding products, in order to achieve the flame retardant or antistatic effect of the bedding products, some additives will be added during the processing, but if the rinsing is not in place, some chemical substances will remain in them, resulting in the production. Odor. According to the "National Textile Product Basic Safety Technical Specifications", four kinds of odors such as musty smell, high boiling oil (such as gasoline, kerosene), fishy smell, and aromatic hydrocarbon smell are prohibited from appearing in bedding or clothing.
Smell good or bad
Although ordinary consumers cannot identify product quality by some means, Wang Baojun said that there are also some simple exclusion methods that can say no to some inferior products. "First of all, you can smell it." Wang Baojun said that as long as you smell the product, it is best not to buy this product. Secondly, you can take a look at the color, it is recommended not to buy some bright or dark products. In general, red and black clothes are more likely to contain azo. In addition, some bedding with a lot of patterns should be vigilant. “The general pattern is glued to the clothes, which is more likely to contain formaldehyde.†You can also use a damp cloth to rub the product you want to buy. If you find the color, it means the color fastness is not good. Such products are also best not to choose.
Do not be superstitious special features
At present, many sheets and quilts on the market are put on high-tech outerwear, such as antibacterial and anti-mite, are these products really effective? Wang Baojun believes that these functions are more for the purpose of propaganda, and there is actually no need to superstitiously these special functions.
According to reports, in general, the current bed antibacterial is mainly for E. coli and Staphylococcus aureus or Candida albicans. However, these fungi appear frequently in life and may be physically present and not very unsafe. E. coli can only be affected if it is eaten in the mouth. Therefore, for bed products, antibacterial does not make much sense.
For some anti-aphid bedding products, experts still believe that the ingredients of the promotion are mostly. Wang Baojun believes that the locusts in life are almost everywhere, even if the bedding products are resistant to mites, there is still no significance in other locations without anti-aphids. As long as the bed is frequently washed and changed, it is often ventilated, and it is basically unnecessary to use anti-mite beds.
