The Shanghai Municipal Bureau of Quality Supervision announced on the 7th that it has recently conducted special supervision and spot checks on the quality of the student uniforms produced and sold in this city. After inspection, 6 batches out of 22 batches were unqualified. Among them, a winter school uniform produced by Shanghai Ouxia Fashion Co., Ltd. was found to be carcinogenic, which is carcinogenic to humans, and the harm to the human body is irreversible, which is a serious quality problem.
We wear clothes every day, but many people may not know that the fabrics of clothes that we touch every day may contain toxic and harmful substances. Experts say that this kind of toxic clothing is no less harmful to the human body than toxic food, and it may also cause cancer. So, what kind of clothing is green safety clothing? How can we avoid the above toxic substances from harming the human body? How can consumers wear it safely?
Doubt 1: Where does the poison come from? How toxic is it?
There are many opportunities for clothing to be contaminated throughout the production process, such as cotton, linen and other clothing materials. In the planting process, in order to control the erosion of diseases, pests and weeds, and to ensure its yield and quality, Insecticides, fertilizers and herbicides are used in large quantities, resulting in pesticide residues in cotton and hemp fibers. Although the pesticide residues are very small after being made into clothing, frequent contact with the skin can also cause harm to the human body. In addition, when textile raw materials are stored, preservatives, antifungal agents, and anti-moth agents should be used. These chemicals remain on clothing and can cause skin allergies, respiratory diseases, and even induce cancer. Chemical substances such as oxidants, catalysts, detergents, and whitening fluorescent agents used in the weaving process make it difficult to avoid fabric pollution, and the pollution in the printing and dyeing process is the most serious. Colorful fabrics certainly satisfy people’s pursuit of vision, but the azo dyes used in printing and dyeing can induce cancer, and formaldehyde, halide carriers, and heavy metals have also become health killers. Objectively speaking, clothing pollution and indoor decoration pollution cannot be synonymous with each other, but because of its direct contact with the human body, its harm over time cannot be underestimated.
Doubt 2: The production of a garment requires many steps such as weaving, cutting, bleaching, dyeing, and packaging. Then in the garment production process, the following steps tend to cause toxins (hazardous elements) There is a chance to get into clothing and harm our body, so we should pay attention to it!
Be vigilant in the spinning process:
(1) Dimethylformamide, an organic solvent in the spinning process of chemical fiber fabrics, is harmful to human skin and eyes. It is irritating to mucous membranes, and skin contact will cause numbness and burning. Some people will also experience skin redness, rash, dryness and other allergic symptoms; inhalation can cause headache, dizziness, fatigue, nausea, vomiting, abdominal pain and other poisoning symptoms, serious Sometimes it can damage the gastrointestinal tract and cause gastrointestinal bleeding. It is also easy to damage the liver, causing general fatigue, poor appetite, hepatomegaly and elevated transaminases.
Be vigilant during the dyeing process:
(2) Formaldehyde, namely formalin, is mainly used as a dyeing auxiliary and a resin finishing agent to improve the anti-wrinkle and shrink-proof effect of clothing . Textiles containing formaldehyde will gradually release free formaldehyde during the wearing process, which will cause inflammation of the respiratory tract and skin through the human respiratory tract and skin contact, and it will also cause eye irritation. Formaldehyde can cause allergies and cancer.
(3) Aromatic amine compounds, decomposable aromatic amine dyes refer to dyes synthesized from carcinogenic aromatic amines, which are often called “banned azo dyes.” Azo dyes are the most diverse category 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., with a complete range of colors, good shade, and certain fastness. Therefore, it is widely used in the dyeing and printing of a variety of natural and synthetic fibers, as well as the coloring of paints, plastics, and rubber. For textile safety indicators, decomposable aromatic amines are far more toxic and carcinogenic than formaldehyde. After the decomposable aromatic amine dye is made into clothes, it is not only insoluble in water, but also colorless and odorless. It cannot be distinguished from the appearance of textiles. It can only be found through technical inspection and cannot be eliminated. In the process of long-term contact with the human body, the harmful components of this dye are absorbed by the skin. Under special conditions, it decomposes to produce more than 20 kinds of carcinogenic aromatic amines, forming carcinogenic aromatic amine compounds. After activation, it changes the DNA structure of the human body and causes disease. And substances that induce malignant tumors, leading to malignant diseases such as bladder cancer, ureteral cancer, and renal pelvis cancer.
Be vigilant during the rinsing process:
