I. test samples and sources

The sample of the comparative test is purchased by the Beijing Consumers Association staff as an ordinary consumer from the large shopping malls in Beijing.

The sample covers 57 kinds of casual pants produced or distributed by 54 enterprises in nine provinces and municipalities in Beijing, Tianjin, Shanghai, Shandong, Zhejiang, Jiangsu, Fujian, Guangdong, Shenzhen and so on.

Two. Test standards and projects

The comparison test results are only responsible for the purchased samples.

Three, test results

In this comparative test, 57 test samples have 37 samples, all test items meet the national standard requirements, accounting for 64.9% of the total samples.

Comparative test results show that a considerable number of enterprises do not monitor the quality of products, and the quality of some casual pants samples can not be directly proportional to their brand awareness or expensive prices.

The main problems are: fiber content is not accurate, color fastness, formaldehyde, pH value is not up to standard.

The concrete results are as follows:

1. Product identification

Logo is an important form of clothing instructions, used to identify products and their quality, reflect product characteristics, reflect the special performance and use of products.

All the samples in this comparison test are in line with national standards.

2. Fiber content

Fiber content is an important symbol to reflect the quality of fabric. It is the most direct way for an enterprise to convey product ingredients to consumers. It is a key factor for consumers to choose casual pants, and it is also an important factor determining the value of trousers.

In this comparative experiment, 51 samples of 57 samples met the national standard requirements, accounting for 89.5% of the total samples; the 6 samples were not consistent with the measured values, accounting for 10.5% of the total samples.

These 6 samples are: samples of the ZARA brand No. 5627/594/700 produced or distributed by SA La Commerce (Beijing) Co., Ltd., the sample number of MCM brand No. 70292527 produced or distributed by Shanghai Zeng Hao industry and Trade Co., Ltd., the sample of the Makasi Ni brand MARCCASNE produced or distributed by Xiamen Yu Chen garments Co., Ltd., the sample number of Gallery licensed by Gallery, the sample produced or distributed by the Shenzhen metal Star Clothing Co., Ltd., the sample produced by Beijing Kabolo Garments Co., Ltd., which is produced by the Beijing Clothing Co., Ltd., the sample number of CAPEL CAPEL licensed by Beijing Clothing Co., Ltd., the sample of all licensed products sold or sold by the Beijing law world clothing Limited company, 70292527.

3, formaldehyde content

Clothing products with too high formaldehyde content will gradually release formaldehyde from the garment during the wearing process, which will cause harm to the human body through skin and respiration.

Long term exposure to formaldehyde can cause irritation and edema, headache, weakness, dermatitis, eczema, swelling, swelling and pain in the respiratory tract.

Therefore, the national standard has strict restrictions on formaldehyde content: formaldehyde content of class B products is less than 75mg/kg, and formaldehyde content of C products is less than 300mg/kg.

In this comparison, 57 samples, 2 samples of formaldehyde content does not meet the national standard requirements, accounting for 3.5% of the total number of samples, they are: Guangzhou Taimai Clothing Co., Ltd. production or distribution of gold crocodile brand number is 308501-2 (class B) samples, the measured data are 107mg/kg, Beijing true friend Trading Co., Ltd. production or distribution of Bryan BRUIN brand number BA3MPL02AGN (B class) samples, the measured data is 95mg/kg.

4, pH value

PH value is an index for assessing the pH of clothing fabrics.

Human skin is weakly acidic. If the pH value of the textile is too large to the human skin, it will stimulate the skin. The national standard requires that the pH value of the textiles directly contact the skin should be within the range of 4.0-7.5. The pH value exceeds the standard limits, which will damage the skin's balance and resist the energy, causing skin allergy or inducing infection, and making the skin vulnerable to other pathogens.

In this comparative test, 3 samples were measured and the pH value exceeded the national standard requirements, accounting for 5.3% of the total samples. They were: the gold crocodile brand number 308501-2 produced or distributed by Guangzhou Taimai Garments Co., Ltd., the measured value of pH was 3.2, the sample of the Weiming W&M brand number CB3610 produced or distributed by Weiming Garment Industrial Co., Ltd., Fujian, Shishi, the measured value of pH was 8.6, and the G2000 brand number produced by Shenzhen Hui Jun Garments Co., Ltd. was GMC06W130E06552002, and the pH value was 7.9.

5. Color fastness

The use of textiles and the fading and staining of light colored clothing after washing have always been a matter of concern to consumers.

Color fastness index is mainly to check the dye must be fasten on the fiber. Otherwise, the dye will fall off and pfer to the skin during the wearing process, which will harm the human body or stain the light colored clothes, which will bring trouble to the consumers.

In this comparative test, I will test the 7 color fastness indexes of samples, such as soaping, water resistance, sweat resistance, dry friction, moisture resistance, dry cleaning and light fastness, and the color fastness indexes of the 41 samples meet the national standard requirements, accounting for 71.9% of the total samples.

6. Odor and banned azo dyes.

Peculiar smell refers to the volatile special odors emitted from textiles, indicating that there are excessive chemical residues on textiles or chemical or biological deterioration of textiles, which is harmful to human health. Banned azo dyes, azo dyes containing carcinogenic aromatic amines, can cause harm to the human body. Such dyes on the fabric are in contact with human body for a long time, causing human cells to mutate and induce cancer or cause allergies.

After testing, the two indexes of the 57 samples meet the requirements of the national standard.

The result of the casual pants test is not satisfactory. It is understood that the reason for the defect of product quality is that some enterprises reduce the cost and save the cost of testing. Only the data supplied by the supplier and the data are not detected before the production, resulting in the fiber content, color fastness, formaldehyde and pH value which do not meet the national standard requirements. Two, the enterprise obtains the test report, the purpose is only to meet the requirements of the shopping malls, only to detect several indicators, resulting in the false appearance of the enterprise products in line with the national standards.

Four, remind consumers

1, consumers first pay attention to the identification of products, according to the national standard, B clothing can directly contact the skin, C clothing is not suitable for direct contact with the skin, consumers can choose suitable clothing according to the needs of clothing.

2, when consumers choose casual pants, they should pay attention to the appearance quality of the products, check the materials and quality grades according to the needs, and see if the contents of the labels are consistent with the actual situation of the goods.

3, for safety and hygiene, consumers are advised to wear new casual pants after washing.

4, the correct wear and maintenance of clothing is a key to durable wear. Proper wear and attention should be made to permanent washing, marking and operation, and washing of deep and shallow clothes to prevent contamination. When using detergents, they should have color clothes to avoid the obvious detergents of whitening and bleaching.

5, consumers should purchase clothing from reputable shopping places and retain their shopping vouchers so as to effectively protect their legitimate rights and interests after quality problems arise.
