Guangzhou Municipal Council: Report On The Comparison Test Of Children And Infant Garments

The skin of young children and infants is very delicate, and the resistance to external friction and bacterial erosion is weak. Therefore, many parents are especially concerned about the safety of children and infant clothing.

In order to guide consumers to choose these products reasonably, the Guangzhou Municipal Council recently conducted a comparative experiment on children's clothing sold on the market in Guangzhou, and the results are announced.

I. General Situation of comparative experiments

This comparative test sample is purchased by our staff to simulate the general consumers' identity and the staff of the inspection station in the major shopping malls and supermarkets in the city.

The sample involves high, medium and low grade children and infant clothing.

And commissioned the Guangzhou Fiber Products Testing Institute for testing.

Inspection standards: "national textile products basic safety technical specification" GB 18401-2003, "consumer goods instructions for use of textiles and clothing" GB 5296.4-1998, "textile fiber content logo" FZ/T 01053-2007, "children's clothing, student wear" FZ/T 81003-2003, "knitted T-shirt" GB/T 22849-2009, "knitted casual wear" FZ/T 73020-2004, "infant knitted dress" FZ/T 73025-2006, "infant clothing" FZ/T 81014-2008, the existing effective corporate standards, product quality indicators and requirements, and their corresponding product standards.

(two) the test items are: label (identification), fiber composition, formaldehyde, pH value, decomposable aromatic amine dye, water fastness, sweat fastness, color fastness to rubbing, color fastness to washing, fastness to light, saliva fastness, sewing strength and extractable heavy metal content.

Two. Comparison test results and analysis

A total of 50 batches of samples were purchased, including 37 batches of children's clothing and 13 batches of infant garments.

After inspection, the inspection items are completely consistent.

Quality test of children and infant clothing comparison test

The product type purchase batch is in line with batches of non conforming batch rate (%), pure identification does not meet the batch physical quality conformity rate (%).

Children's clothing 37191851.351 54.05

Infant clothing 139469.232 84.62

Total 50282256.003 62

The comparison test was conducted on batches of substandard batches.

(1) important safety performance

1. formaldehyde content exceeded standard

Formaldehyde, commonly known as formalin, is commonly used as a biological preservative and an important indicator for human health.

Excessive formaldehyde content in clothing will stimulate children's respiratory tract and skin mucous membrane, which can cause respiratory injury and cause various kinds of inflammation.

Skin contact with formaldehyde can cause sensitization, rash and other reactions.

The toxicity of formaldehyde to infants is manifested by asthma, tracheitis, chromosomal abnormalities and resistance.

According to the national mandatory standard GB 18401, the formaldehyde content of the textiles directly contacting the skin is less than 75mg/kg, and the infant products require formaldehyde content less than 20mg/kg.

The comparison test showed that 1 batches of samples had formaldehyde content exceeding the standard and the detection value was 80mg/kg.

In the process of fabric finishing, if the use of low cost formaldehyde containing finishing agents or auxiliaries, the formaldehyde content will exceed the standard.

2.pH value does not meet the standard requirements.

The pH value is an index reflecting the acid-base of goods.

Because the surface of the human body is weakly acidic (the pH value of healthy skin is between 5 and 5.6), the pH value of clothing products is too high or too low, which may damage the balance of human skin pH, cause skin allergy or infection, and make the skin vulnerable to other pathogens.

The national mandatory standard GB 18401-2003 stipulates that the pH value of infant clothing products and clothing products directly touching the skin must be between 4 and 7.5. GB 18401-2010 also stipulates that the pH value of infant clothing must be between 4 and 7.5, and the pH value of clothing products directly touching the skin must be between 4 and 8.5.

And this comparison test found that 3 batches of samples pH value exceeded the standard, and all of the alkalinity, the highest detection value reached 9.7.

The following reasons may cause the pH value of the product not to reach the standard: the clothing manufacturer is not strict in selecting raw materials, while the raw material manufacturer has high pure cotton products and high cotton content in dyeing and finishing process.

(two) colour fastness

Color fastness (color fastness) refers to the dyeing of textiles in the use of sunlight, water, sweat, friction and other external factors or processing, textile dyes on a variety of factors to maintain their original color performance in different degrees, is an important indicator of the quality of clothing.

When dyed clothes with poor color fastness are exposed to water, sweat, sun or physical friction, dyes are easy to fall off and fade, affecting beauty. And the falling dye molecules or heavy metal ions may be harmful to health through skin absorption by human body.

The color fastness of children and infant clothing is not allowed to be ignored. Among them, 3 batches and 6 batches of products do not meet the standard requirements.

The following reasons will cause excessive color fastness: the product used inferior dyes in dyeing, inadequate washing after dyeing, or incomplete finishing.

(three) fiber content

The mandatory national standard GB 5296.4-1998 "instructions on the use of textiles and clothing for consumer goods" clearly stipulates the contents of fiber components in textiles, clothing and fabrics.

A total of 11 batches of samples do not meet the standard requirements of this project. There are two main aspects: first, the measured fiber content is not consistent with the marked value, such as "cotton 100%". The measured results are "viscose 61.5%, cotton 38.5%"; two, the measured fiber is not consistent with the fiber name of the label.

If the "polyester fiber 100%" is labeled, the measured result is "nylon 100%".

Fiber content is one of the important reference materials to guide consumers to purchase products and determine the value of products.

If the fiber content does not conform to the standard or the identification of no fiber components will harm the legitimate rights and interests of consumers.

Fiber content does not meet the standard requirements for two main reasons: first, enterprises pay less attention to the content of fiber when purchasing fabrics, and do not take effective measures to check the composition and content of fiber. Two, some enterprises do not understand the standard, leading to incorrect marking of fiber components.

(four) product identification

Although the identification project has little effect on the safety of products compared with other items, in order to ensure the safe use of products, the mandatory standard GB 5296.4 clearly stipulates that the production enterprises should still attach importance to it.

The comparison test showed that 5 batch samples of the identification project did not meet the standard requirements.

It is shown in the following three aspects: first, incorrect marking or incorrect marking; two, unlabeled fiber content or incorrect marking; three, unlabeled washing methods or incorrect marking.

The project does not meet the standard requirements, indicating that some producers and distributors have vague understanding, incomprehending and incomprehending standard requirements, resulting in intentional or unintentional omission or mislabeling.

Three, consumption proposals

When buying clothes for children and infants, we should pay attention to whether the labels are complete or not. Smell some unpleasant odors, try to buy light colored clothes, and buy less pigment printing products. Pay attention to check the safety of metal zippers, buttons and accessories for children's clothing.

Remarks: the test result is only responsible for the sample, not the same.
