Attention Should Be Paid To Label And Color Fastness Of Imported Children'S Textile Products?

The label is unqualified, the color fastness is unqualified, and the fiber content does not reach the declared level In recent years, the children's consumer market continues to expand, and the consumption concept turns to the high-end field of pursuing quality and brand. The children's home textile industry has developed rapidly. However, some of the imported children's textile products favored by consumers still have some product quality problems. As March 15 is approaching, Huangpu Customs laboratory sorts out the inspection results of imported children's textile products for consumers, reminds consumers to check the cleanliness of the products, observe whether they have complete marks, and pay attention to keeping relevant certificates as an important basis for rights protection.

In recent years, unqualified products have been found repeatedly in the quality and safety risk monitoring and random inspection of customs. The main product quality problems include unqualified label, unqualified color fastness, fiber content can not reach the declared level, etc.

The label is unqualified

Identification and instructions are important sources for users to obtain product information, and also important basis for normal use and maintenance of users. For infant and children's textile products sold in China, relevant product marks shall be marked in simplified Chinese as required, so that consumers can clearly understand the source information, model and fiber content of the product, such as the executive standard number, registered trademark, etc. Consumers can get a simple understanding of product quality through these information.

Taking the spot check data of Huangpu Guan District as an example, the proportion of disqualification of various labels is as follows:

The color fastness is unqualified

The so-called color fastness (hereinafter referred to as color fastness), commonly known as anti fading, refers to the degree of fading of dyed fabrics under the action of external factors (extrusion, friction, washing, rain, exposure, light, seawater immersion, saliva immersion, water stains, sweat stains, etc.) in the use or processing process of dyed fabrics. It is an important index of fabrics.

The unqualified color fastness not only affects the service life of the product, but also pollutes other clothes. In addition, when the product with poor color fastness encounters rain and sweat, the pigment on the fabric falls off and fades, and the molecules and heavy metal ions of the dye may be absorbed by the human body through the skin and endanger human health.

After a series of color fastness tests, the color fastness grade is finally determined by using the color comparison card for grade comparison.

Colorimetric process: the fiber content does not reach the declared level

It is found that the fiber quantitative analysis of some products does not meet the standard requirements.

For example, the color socks in the above figure have the following problems: first, the nominal value of fiber content is inconsistent with the actual test results; second, the name and address of the agent or importer or seller of the product registered in mainland China is not indicated.

Small knowledge:

About fiber content

Textile fiber content is an important component of textile label, and also an important basis for consumers to determine the value of products. The standard GB / T 29862-2013 "identification of textile fiber content" specifies the requirements of label, labeling principle, indication method, allowable deviation and identification conformity judgment of textile fiber content. For all textiles sold in China, the labeling of fiber content must conform to the nominal value.

Fiber content detection: this test item is divided into two parts: qualitative analysis and quantitative analysis. Qualitative analysis generally uses one or more of the testing methods such as tensile test, combustion method, microscope method, dissolution method, infrared spectrum method to determine the specific types of fiber contained in the sample (such as cotton, hemp, wool, polyester fiber, nylon, etc.), and then according to the sample's According to the structure type and fiber distribution, one or more methods, such as manual yarn splitting method, chemical dissolution method and fiber projector method, are used to determine the specific content ratio of various fibers.

For example, after the above qualitative analysis method is used to determine the fiber types of cotton, nylon and spandex, the chemical dissolution method is used to dissolve the nylon and spandex contained in the sample, and the remaining fiber is cotton fiber. Finally, combined with the calculation formula, the specific fiber content is calculated.

The process of microscopical analysis is cumbersome and the calculation is more complex. A group of samples needs nearly two hours of work. Therefore, the customs and scientific research institutions jointly developed the intelligent AI fiber content quantitative and qualitative analyzer to improve the detection efficiency through image recognition technology.

Consumption tips:

As non professionals, how to choose when buying imported children's textile products?

The first is appearance observation, to check the cleanliness of the product and observe whether it has complete identification, including product instructions and durability labels; whether the supplier's name, product name, product type and specification are clearly marked; the ingredients and content of raw materials, washing method, product standard number, product quality grade, product quality inspection certificate and safety are clearly marked Technical category and other contents that must be marked.

Second, sensory evaluation, can smell the product close to whether there is a pungent smell, especially the products packed with folding tape. If there is a pungent smell, we should be vigilant. The product may have quality problems such as excessive formaldehyde and carcinogenic aromatic materials.

The third is to keep the certificate. In a period of time after the purchase of the goods, try to keep all the certificates related to the goods, including purchase bills, clothing tags, etc., which can not only be used to guide product maintenance, but also be used as an important evidence for rights protection in case of quality disputes.
