Clothing "toxic" harm geometry?
We wear clothes every day, but many people may not know that the fabrics that are in contact with each day may contain toxic and harmful substances to the human body. Experts say that this toxic clothing is as harmful to the human body as toxic foods and may cause cancer. So, what kind of clothing is green safety clothing? How can we avoid the toxic substances on the human body? How should consumers wear safety? Interpretation 1: Where does the poison come from? How big is the toxicity? There are many opportunities for clothing to be contaminated throughout the production process, such as cotton, hemp and other clothing materials. In order to control the erosion of diseases, insects and weeds during the planting process, to ensure its yield and quality, a large amount of pesticides, fertilizers and herbicides are needed. Etc., causing pesticides to remain in cotton and hemp fibers. Although the amount of pesticide residues after making a garment is very small, frequent contact with the skin can also cause harm to the human body. In addition, textile materials should be stored with preservatives, anti-mold agents, and anti-caries agents. These chemicals can remain on clothing, causing skin irritation, respiratory illness, and even cancer. Chemicals such as oxidants, catalysts, detergents, whitening fluorescers used in the weaving process make fabric contamination difficult to avoid, and the pollution of printing and dyeing is the most serious. The colorful fabrics satisfy the people's visual senses, but the azo dyes used in printing and dyeing can induce cancer, and formaldehyde, halide carriers and heavy metals have become health killers. Objectively speaking, clothing pollution and indoor decoration pollution can not be the same, but because of its direct contact with the human body, the damage may not be underestimated. Interpretation 2: The production of a garment needs to go through many steps such as textile, cutting, bleaching, packaging, etc. In the process of garment production, the following steps often make the toxin (hazardous element) organically enter the garment and endanger our body. Should attract our attention! Be wary of the textile process: (1) Dimethylformamide is an organic solvent in the spinning process of chemical fiber cloth. It is irritating to human skin, eyes and mucous membranes. There is numbness and burning sensation in skin contact. Some people may also have redness and rash on the skin. Allergic symptoms such as dryness; inhalation can cause headache, dizziness, fatigue, nausea, vomiting, abdominal pain and other symptoms of poisoning. In severe cases, it will also hurt the gastrointestinal tract, causing gastrointestinal bleeding; it is also easy to damage the liver, and there is general malaise and appetite. Poor, there may be cases of hepatomegaly and elevated transaminases. Be alert during the dyeing process: (2) Formaldehyde, that is, formalin, is mainly used for dyeing auxiliaries and resin finishing agents for improving the anti-wrinkle and shrink-proof effect of garments. Formaldehyde-containing textiles gradually release free formaldehyde during the wearing process, causing inflammation of the respiratory tract and skin through the human respiratory tract and skin contact, and also irritating the eyes. Formaldehyde can cause allergies and can also cause cancer. (3) Aromatic amine compounds, decomposable aromatic amine dyes are dyes synthesized from carcinogenic aromatic amines, which are often referred to as "banned azo dyes". Azo dyes are the most widely used types of synthetic dyes. Many direct dyes, acid dyes, disperse dyes, reactive dyes and cationic dyes are all azo dyes. Azo dyes have a wide range of chromatograms, including red, orange, yellow, blue, purple, black, etc., complete color, good color, and a certain degree of fastness. Therefore, it is widely used in the dyeing and printing of a variety of natural and synthetic fibers, as well as in the paint, plastic, rubber and other coloring. For textile safety indicators, the toxicity and carcinogenicity of decomposable aromatic amines are much stronger than formaldehyde. Decomposable aromatic amine dyes are not only insoluble in water, but also colorless and odorless. They are indistinguishable from the appearance of textiles and can only be discovered through technical inspection and cannot be eliminated. In the process of long-term contact with the human body, the harmful components are absorbed by the skin, and under special conditions, it decomposes to produce more than 20 carcinogenic aromatic amines, which form carcinogenic aromatic amine compounds, which change the DNA structure of the human body through activation and cause lesions. And induce malignant tumor substances, leading to malignant diseases such as bladder cancer, ureteral cancer, and renal pelvic cancer. Be alert during the rinsing process: (5) Linear alkyl iodate, some of which are rinsed with a synthetic detergent, and the chemical components such as alcohol, sulfuric acid and linear alkyl iodate may be absorbed into the human body through the skin, if the rinse is not clean, Incomplete, long-term wear can also cause infertility in women. Be wary of packaging anti-corrosion process: (6) Naphthalene, some wool or silk garments are insect-proof, often treated with naphthalene. Naphthalene is easy to volatilize and is easily absorbed by mucous membranes, skin and subcutaneous tissues, and can cause harm to human body. In addition, the fine down fiber in down garments can be a sensitizing source after being in contact with human skin or inhaled into the respiratory tract, causing the body's capillaries to dilate, the blood vessel wall to be highly permeable, the serum protein and water to seep or a large amount of penetration into the skin. Tissue, the body has different degrees of redness, rash, wheal, itching and other reactions. Interpretation 3: How to buy "green clothing"? 1. Generally speaking, light-colored clothing is more environmentally friendly than dark ones. Because the fabrics of light-colored garments are less likely to be contaminated during the production process, especially in close-fitting underwear. From a health point of view, it should be lighter. 2. When you choose clothing, you can choose not to have lining. For suits and other products that must be lined, you can choose non-stick lining technology products. Because the adhesive liner requires glue, the glue usually contains a solvent such as formaldehyde. 3. Many people like to buy foreign trade clothing, but be careful when buying, don't buy back products that have been returned for environmental reasons. 4. The green-certified clothing has a one-time laser holographic anti-counterfeiting mark, which can be illuminated by a laser pen, and 10 rings can be seen at any angle. 5. When you buy clothes, you may want to smell it. Most of the clothing with mildew, kerosene smell, fishy smell, benzene smell and other odors exceeds the standard and cannot be purchased. 6. Try not to buy non-iron clothes. Especially those who are allergic to formaldehyde, can't wear non-iron clothing. 7. Just buy the non-iron clothes, do not immediately hang into the closet, it is best to use the water to fully rinse and then wear to reduce the formaldehyde content in the clothing. 8. After wearing new clothing, if skin irritation such as skin itching, contact dermatitis, or mood swings, poor diet, continuous cough, etc., consider whether the clothes are not suitable, and go to the hospital as soon as possible. Interpretation 4: What is the code name on the fabric? How to identify? There are 5 codes on the clothing, the first digit represents the raw materials used in the goods, the second digit represents the fabric organization of the merchandise, and the back is the serial number of the merchandise. Before this number, the uppercase English letters are used to represent the origin of the merchandise. From the number of the product, the raw materials and origin of the product can be identified.
