Expert Interpretation Of Infant Clothing Product Quality

　 Product Brief

Infant clothing is used by infants aged less than 36 months or below 104cm and below. clothing 。 Because infants' skin and body are more delicate than adults, they are more sensitive to toxic and harmful residues of clothing fibers and textiles. standard China has put forward more stringent requirements for infant clothing.

　　 Key indicators

1. component content. The content of ingredients refers to what kind of fibers the clothing products are made from. fibre Generally divided into two categories: natural fiber and chemical fiber. Natural fibers include cotton, linen, wool, rabbit hair, silk and so on. Chemical fibers include polyester, acrylic, viscose fiber and acetate fiber. Recently, soybean fiber and modal fiber are also chemical fibers. Because cotton fiber has the characteristics of strong hygroscopicity, good air permeability and little irritation to skin, cotton fiber is generally recommended as raw material for processing infant clothing.

2. formaldehyde content. The formaldehyde in clothing mainly comes from various finishing agents, fixing agents, waterproofing agents, softeners and adhesives used in the process of clothing finishing. When the free formaldehyde content exceeds the standard, it will cause strong irritation to the respiratory tract and skin of the human body, causing inflammation and dermatitis of the respiratory tract, and irritating the eyes. Long term intake of low concentration of formaldehyde can cause loss of appetite, weight loss, weakness and insomnia. The toxicity to infants is manifested as asthma, tracheitis, chromosomal abnormality, and decreased resistance. If long-term exposure to formaldehyde gas, or even induce cancer. In the national standard, the requirement for formaldehyde content in infant clothing is strict with adult clothing, and the formaldehyde content in each kilogram of fabric should not exceed 20 mg.

3.pH value. The pH value refers to the pH value of the fabric. The surface of human skin is generally weak acidic. The pH value is between 5.5~7.0. It has the function of protecting the skin from bacteria. The main reason for the human body's allergy to textiles is that the skin is exposed to the residual alkali which is not cleaned and remains on the surface of the garment. The natural barrier on the skin surface is damaged, stimulating the skin, causing bacteria and causing diseases. Infants will be more sensitive to clothing with pH value exceeding standard, which may lead to dermatitis, skin swelling and other symptoms. Therefore, the standard stipulates that the pH value of textiles should be controlled in neutral and weak acidity (i.e. pH value is 4.0~7.5).

4. smell. Peculiar smell mainly refers to the smell of clothing, gasoline, fishy smell, aromatic hydrocarbon smell and so on. The strong smell indicates that excessive chemicals or harmful ingredients remain in clothing, which may be harmful to health.

5. decomposable aromatic amine dyes. Textile products should be dyed with various dyes during printing and finishing. The dyes used in modern printing and dyeing industry are azo dyes. Through the long-term study of clothing textiles, it is found that some azo dyes may decompose aromatic amines with carcinogenic effects. Clothing that is dyed with such dyes will be mixed with human skin for a long period of time. It will mix with the substances released in the process of human metabolism and produce a reduction reaction to form carcinogenic aromatic amine compounds, which will cause changes in the structure and function of DNA in human cells, leading to physical changes.

　　 Shopping Tips

1. choose the place of purchase. Generally speaking, the products sold in large shopping malls, franchised stores and supermarkets have passed the examination, selection and inspection of suppliers. Consumers can ask the merchant to see the inspection report of the product.

2. choose brands. Generally speaking, the well-known brand manufacturers have more perfect and sound quality assurance systems, and pay more attention to the quality and credibility of products, and the quality of products is more reliable.

3. read the product logo carefully. According to the mandatory national standard, the logo of infant clothing must include two kinds of tag and durable mark (the collar or waist head that is stitched on clothing, which can be retained on clothing for a long time). The products should be marked with the name of the product, the name and address of the production enterprise, the washing method, the size specification, the content of the raw material, the product standard number, the product quality grade and the safety technology category, and the words "baby products" must be marked on the logo.
