1, not wear-resistant.
Some socks have holes after being worn twice, and people will think that this is caused by improper wearing. In fact, this shows that the wear resistance of socks is unqualified. Experts said: socks need to add high-strength fibers to important parts such as toes and heels, and adopt more scientific knitting technology to ensure wear resistance, and more than half of the samples tested this time have poor wear resistance. In order to cater to consumption, stall socks are generally cheaper. Socks with poor wear resistance often use low-grade materials, which are not only easy to wear out, but also may scratch the feet, resulting in heel injury or blistering.
2. Serious fading
The dyeing fastness of socks is also an important indicator of whether socks are qualified or not. According to the regulations, the dyeing fastness of socks should reach grade 4, that is, it will basically not fade. However, in one test, many samples failed in the color fastness index, and some even reached 1 level. Grade 1 means that when I wash a white dress with such dark socks, the colors of the latter two items will become indistinguishable.
The problem caused by the fading of socks is not only the pollution of other clothes, but also the addition of various dyes, auxiliaries and other finishing agents to textile products in the process of printing, dyeing and finishing will contain or produce substances harmful to human body to a greater or lesser extent.
3. Pilling and hair loss
After a hard day's work, when I went home to take off my socks and wash my feet, I found that the broken fibers lined in the socks were firmly stuck to the skin of the foot layer, which greatly reduced the permeability of the skin. Moreover, the toe of the sock is seriously pilling with important parts, and it will leak over time.
Step 4 lose elasticity
When socks lose their elasticity, they will increase the friction with their feet and will not follow them when walking or exercising. If they sweat, they will feel greasy and get hurt easily.
5, uncomfortable to wear
In recent years, socks produced by socks factory are mostly tight-mouthed, often pulling the ankles tightly and even pulling out red marks. The local compression of the ankle by the sock mouth often leads to the increase of blood pressure, and even leads to heart disease in severe cases. If your feet feel uncomfortable, such as tightness, itching and obvious strangulation marks, then socks are not suitable.
6. Formaldehyde and aromatic amine exceed the standard.
According to the process, the manufacturer should wash the socks thoroughly before leaving the factory. Because a large amount of alkaline substances will be used in the whole production process, socks that are not thoroughly cleaned will be detected to have a high pH value. Both formaldehyde and alkali can cause certain harm to the skin, such as allergic inflammation.
Formaldehyde in socks is far more terrible than clothes. This is because the sweat glands, blood vessels and nervous system of human soles are very developed. When the feet excrete some body fluids, these body fluids may cause the decomposition of dyes. In addition, the harmful substances in socks are not easy to spread, and will constantly rub against the feet, increasing the impact on the skin.
From this point of view, the quality of socks is directly related to our physical and mental health, and small socks are healthy. I hope you don't ignore the invisible killer hidden around us! "The United Nations advocates a low-carbon life, which is very consistent with our products."
