Guangdong: Results Of Unqualified Products In Clothing Spot Checks

In 2015-2016, the Guangdong Provincial Administration for Industry and Commerce commissioned the Guangzhou textile products inspection and Research Institute to conduct spot checks on the quality of clothing products in the circulation sector in the province. In the 7 prefecture level cities such as Guangzhou, Shenzhen, Dongguan, Jieyang, Maoming, Meizhou and Shantou, 67 samples of 240 clothing samples were distributed, involving 131 manufacturers.

A total of 94 clothing products were found to be unqualified by inspection, 93 of which were totally unqualified, 1 of them were unqualified, and the other 146 samples were not found to be unqualified. The sampling rate was 39.17%.

The sampling outlets include shopping malls, self-employed persons and online shopping centers.

Among them, 34 shopping malls altogether drew 142 garments, 30 self-employed households drew 73 garments, and 3 online shopping centers drew 25 garments.

Judging from the inspection results, the online shopping mall clothing failed to detect the highest rate, reaching 60%; the disqualification rate of shopping malls and self-employed households was 38.7% and 32.9% respectively.

This sampling survey mainly involves the safety performance indicators of the public and other main indicators of products, including: marking, fiber content, formaldehyde content, pH value, decomposable carcinogenic aromatic amine dyes, water fastness, sweat fastness, dry rubbing color fastness, wet rubbing fastness, washing (or soaping) fastness, dry cleaning fastness, light fastness, light fastness, color fastness and joint performance.

The main unqualified items were: 20.8%, joint performance (or slip) 15%, fiber content 11.3%, moisture resistance rubbing fastness 3.3%, pH 2.9%, fastness to light fastness 1.7%, dry cleaning fastness 1.3%, decomposable carcinogenic aromatic amine dye 1.3%, formaldehyde content 0.4% and washing (or soaping) color fastness 0.4%.

The sampling found that the quality problems of clothing products are: first, a few clothing products Detect decomposable carcinogenic aromatic amine dyes; two, formaldehyde content is higher than the standard limit value; three is the pH value exceeds the standard allowable range; four is the color fastness, joint performance (or crack) and other performance indicators do not meet the standard requirements, five is the fiber content is not consistent with the label, six is the label (product instructions) label is incorrect or not marked.

The main effects of unqualified items on consumption are as follows:

(1) decomposing carcinogenic aromatic amine dyes.

Decomposable carcinogenic aromatic amine dyes are important safety indicators that affect human health. When products containing decomposable carcinogenic aromatic amine dyes are exposed to human body for a long time, if dye is absorbed by the skin, it will spread in the human body, which may cause human diseases and induce cancer.

The national mandatory standard GB 18401-2010 clearly stipulates that decomposable carcinogenic aromatic amine dyes are prohibited.

3 samples of decomposed carcinogenic aromatic amine dyes were found to be unqualified, involving 3 brands, of which 2 products were extracted from the sales outlets of self-employed households, and the details were shown in Table 1.

The main reasons for the disqualification of decomposable carcinogenic aromatic amine dyes are: the dyestuffs or pigments that can decompose carcinogenic aromatic amines are used in the dyeing and printing of fabrics and accessories, while garment manufacturers do not strictly control the quality of the surface and excipients when purchasing raw materials, which will result in the final products being decomposed, and the carcinogenic aromatic amine dyes are not qualified.

(two) formaldehyde content.

Formaldehyde has been identified by WHO as the first category.

。

The sampling test found that the formaldehyde content of the 1 garments exceeded the standard, accounting for 0.4% of the total sample. The "JUICY COUTURE" brand of women's Woven jeans trousers made by Hua Stirling Commerce (Shanghai) Co., Ltd. was 168 mg/kg in the thigh, exceeding the standard (less than 75mg/kg) limit value more than two times, and the sampling place was shopping malls.

The main reason for its unqualified formaldehyde content may be to increase the wrinkle effect of trousers on the thigh, add crosslinking solid formaldehyde to the auxiliaries, and then do not clean the residual formaldehyde after making the finishing process, which causes the hidden danger of excessive local formaldehyde emission and poses a threat to the health of consumers.

(three) pH value.

The pH value is an index to measure the acid and alkali content of textile and clothing products.

The human skin is weak acidic to prevent the invasion of germs. The pH value of textiles is beneficial to the protection of human skin health between weak acid and neutral.

If the pH value is too high or too low, it will damage the surface balance of the skin, causing skin allergy or inducing infection, making the skin vulnerable to other pathogens.

According to the national mandatory standard GB 18401-2010: the pH value of direct contact with skin products should meet the requirements of class B indicators at least, that is, between 4 and 8.5; the pH value of non direct contact with skin products should meet the requirements of C class indicators at least, that is, between 4 and 9; and the pH value of infant clothing products should meet the requirements of class a indicators, that is, between 4 and 7.5.

The sample has 7 commodities pH value is not qualified, involving 7 brands, and 6 goods sampling place for shopping malls, specifically as shown in Table 2.

The main reasons for the unqualified pH value of clothing products are: no fabric washing or acid neutralization treatment is done in the finishing process, or the neutralization is not enough, resulting in the pH value of the fabric exceeds the standard allowable range. While the clothing enterprises purchase raw materials, the quality of the raw materials is not strictly controlled, and the effective inspection measures for the raw material pH value are not taken, resulting in the pH value of the finished products being unqualified.

(four) color fastness.

Color fastness refers to the use of dyed textiles.

In the process, dyes on textiles are subjected to various factors (such as sun drying, water washing, sweat dipping, rubbing, etc.) to maintain their original color and performance in varying degrees.

Dyestuffs with poor color fastness are easy to fall off and fade in the course of use, and affect the appearance. The dye molecules or heavy metal ions that fall off may be harmful to health through the absorption of skin by human body.

The mandatory standard GB 18401-2010 has clear requirements for water resistance, sweat resistance, dry friction and saliva color fastness, while the relevant product standards also have specific requirements for washing, soaking, dry cleaning, light fastness, light fastness and perspiration fastness.

14 samples of clothing products failed to meet the standard requirements. The substandard items involved color fastness to wet rubbing, color fastness to washing (or soaping), color fastness to dry cleaning and fastness to light.

There are 14 brands of unqualified goods, 8 of which are shopping malls, 4 of which are self-employed, 2 of which are online shopping centers, as shown in Table 3.

There are three main reasons for the unqualified color fastness: first, the choice of dyes is not correct, and the suitable dye is not selected according to the fabric type; two, the dyeing process is unreasonable, such as the appropriate dyeing time, heating rate and holding time, etc., according to the type of dye and product, and three, some enterprises have not adopted corresponding washing measures or inadequate water washing to save costs.

(five) fiber content.

Fiber content is

The main quality index, the quality of textile raw materials, is one of the important factors that determine the value of the product.

Because consumers often choose to purchase textile products according to the indicated fiber content, incorrect or unlabeled fiber contents will directly affect consumers' purchase of clothing.

The national standard GB/T 29862-2013 "logo of textile fiber content" clearly stipulates the fiber content of textile fabrics or fabrics.

This sampling inspection has 27 commercial fiber content unqualified, involving 22 brands, of which 12 goods sampling sites are self-employed, 8 commodity sampling sites for shopping malls, 7 commodity sampling sites are online shopping malls, the list of substandard goods and enterprises, as shown in Table 4.

The reasons for the unqualified fiber content are: first, the quality consciousness of the enterprise is weak, and the fiber content is not marked according to the standard requirements, or is blindly marked according to the data supplied by the supplier or is tagged at random according to the estimated fiber content; second, the enterprise only partially inspected the fabric used to save the testing cost, but the fabric content of different batches of fabrics or different parts may be different, resulting in disqualification. Third, some enterprises ignore the marking of low fiber and only label the main fiber components; besides, they do not exclude a small number of enterprises from deliberately making inferior ones, instead of high performance and high value fibers instead of high performance fibers, so as to deceive the consumers and gain illegal profits.

(six) seam performance (slip).

The performance of the joint is used to assess the degree of slippage of the yarn after the external force is exerted on the garment during its wearing or using. It is also known as the degree of slip or crack.

Joint performance is the main index to evaluate durability performance of woven garment products. The unqualified seam performance will not only affect the appearance of the garment, but also greatly affect the service life of the garment.

This sampling inspection has 36 pieces of goods joint performance (slip) unqualified, involving 32 brands, 22 of which are shopping malls, shopping malls, 7 commodity sampling sites are self-employed, 7 commodity sampling sites are online shopping centers, the list of substandard goods and enterprises is shown in Table 5.

The reasons for the failure of the project are: first, the quality of the fabric is not good, such as too thin fabric, loose structure and so on; two, the sewing process is unreasonable, such as insufficient stitch density and improper sewing methods.

(seven) marking.

Markup is the main window for consumers to understand the product's performance. If the label is wrong or unmarked, it may mislead consumers, affect consumers' judgment and purchase products that are not applicable.

The contents stipulated in the mandatory standard GB 5296.4-2012 (the manufacturer's name and address, product name, product size or specification, fiber content, maintenance method, product standard, safety category and other requirements of the product standard) must be clear, accurate and complete.

This sampling inspection has 50 commodity markup which does not meet the standard requirements, involving 33 brands, 27 of which are shopping malls, shopping malls, 13 commodity sampling places are self-employed, 10 commodity sampling sites are online shopping centers, and the list of substandard goods and enterprises is shown in Table 6.

The reason for the unqualified marks is that some producers and distributors are not clear enough to understand the labeling requirements, do not understand them very well, and do not understand thoroughly. They have little knowledge of the labeling requirements, resulting in intentional or unintentional omission of labels and wrong marks.
