Autumn is approaching. Whether in the southern or northern region, underwear is an indispensable warm clothing for consumers in autumn and winter. What brand of underwear is the best quality? The most comfortable wearing comfort? Recently, the Beijing Consumer Association released the results of underwear comparative trials, involving brands such as Jianjun, Yu Zhaolin, Neiwai, Uniqlo and other brands. The results showed that the instructions for the use of five products such as Jianjun, Rouzi, and Caimai Bird did not meet the standard requirements. The actual polyester fiber content of Yu Zhaolin’s sample was lower than the explanatory value. The results also showed that the thickness of the underwear fabric has little to do with warmth. The Beijing Consumer Council reminded that consumers should not blindly pursue the thickness of underwear fabric when buying.

Involved in Jianjian, Yu Zhaolin,

NEIWAI, Uniqlo and other brands

Recently, the Beijing Consumer Association (hereinafter referred to as the “Beijing Consumers Association”) released the “Beijing Consumer Association underwear comparative test results”. This comparison test sample was randomly purchased by the staff of the Beijing Consumers Association from the physical store and online shopping platform. There were 40 samples, including 20 physical stores and 20 online shopping platforms. Wait, it involves brands such as Jianjian, Yu Zhaolin, Neiwai, Uniqlo, and Caisai Bird.

According to the relevant national standards, the product use instructions, fiber content, breathability, kick, insulation rate, unit area quality, pH value, formaldehyde content, water -resistant stain color accuracy, alkali -resistant sweat stains, alkali -resistant sweat stains, alkali -resistant sweat stains The color fastness, dry frictional color accuracy and other indicators were tested. The test results are only responsible for the purchased sample.

After testing, the 34 samples of the 40 samples in this comparison test met the requirements for explicit standards, and the six samples did not meet the relevant standard requirements. It was mainly due to problems such as product use instructions, fiber content, and breathability.

The test results are only responsible for the purchased sample. Tuyuan Beijing Consumer Association official website.

Product use description

The standard labeling of the sample execution is incorrect

Product use instructions are the most intuitive ways to convey product information such as product, basic performance, characteristics and other product information to consumers. They are usually conveyed in the form of manuals, labels, durability logos. In this trial, 40 samples have 5 sample products instructions that do not meet the standard requirements, including five brands, including Jianjun, Phantom, Caiya, Rouzi, Si Yanchen, mainly exist that the name of the manufacturer’s name is not marked. And address, the maintenance method of not labeled the product name, the execution standard is incorrect, the maintenance method of tags and durability labeling is inconsistent.

Among them, the sales unit price is 168 yuan, and the batch/shelter 88jq38 Jianjian samples are incorrect. Sample price of 35 yuan, batch number/item number 1627 sample, has not marked product number or specifications, maintenance methods, fiber composition and content in its durability label.

Fiber content

The actual polyester fiber content of Yu Zhaolin sample is lower than the explicit value

The fiber content is one of the important quality indicators of textile products. It is the most direct way for enterprises to convey product raw materials to consumers. Consumers can understand the quality of the product’s performance and the comfort of wearing through the fiber content of the company. In this trial, only Yu Zhaolin’s underwear sample fiber content did not meet national standards, which was mainly reflected in the range of its fiber content deviation exceeding the standard allowable range.

Judging from the experimental results, the sales unit price of 62 yuan, the batch/goods number YH406J2’s Yu Zhaolin sample, which clearly shows that the polyester fiber content of the bottom layer of the lunatic is 98 ± 5, but the measured value is 89.6, which is lower than the explicit value.

Bird sample permeability in the wealth is lower than the standard requirements

In addition to keeping warm, the underwear is better to have good breathability. Otherwise, the moisture on the surface of the skin cannot be effectively eliminated, and it will slowly condense into water droplets and gather between the surface and clothes of the skin. Uncomfortable. FZ/T 73022-2012 “Knitting Warm Insurance underwear” requires the breathability ≥180mm/s. In this comparison test, the samples that show that this standard sample includes the four models of Arctic velvet, seven wolves, Antarctic people, and wealth birds. After testing, the permeability of bird samples in the wealth did not meet the standard requirements, only 109.7 mm/s.

Sample product samples and hair balls

All meet the explicit product standard requirements

Getting the ball has always been a hot issue for consumer complaints. Generally speaking, the ball is caused by the friction of the surface of the fabric, and the fiber entanglement becomes the shape of the ball. Raising the ball affects consumer use performance. Among the 40 samples of this test, 26 samples were appraised for evaluation. After testing, these 26 samples of the hair balls can meet the product standard requirements of their tags.

Insulation rate

Underwear is not the more heavy fabrics

The better the insulation performance

The insulation rate refers to the ratio of thermal heat energy. Borrowing the thermal resistance of the detection fabric to compare the warmth of the sample. The higher the value, the better the warmth effect. FZ/T 73022-2012 The “Knitting Warm Insurance” standard clearly requires the insulation rate ≥30%. In the samples of this test, the four products of the North Poored, seven wolves, Antarctic people, and Caishen Birds are clearly used in this standard. After experimentation, the insulation rate of these four samples can meet the standard requirements of knitted warm underwear.

It is understood that when choosing underwear, consumers generally think that the thicker clothing, the better, the better, which involves the unit area of ​​the underwear. The quality of the unit area refers to the weight of the weight of the fabric per square meter, which is an important technical indicator for knitted fabrics. Judging from the test results of 40 samples in this comparison, the quality of the sample unit range ranges from 122.2g/㎡ to 422.1g/㎡. Positive relationship, the thickness of the underwear fabric has little to do with warmth.

In addition, after testing, the pH value, formaldehyde content, water-resistant solidity, acid-resistant sweat-resistant color fastness, alkaline sweat stain coloring, dry friction color fastness all samples meet the national compulsory standard GB 18401-2010 ” The National Textile Products Basic Safety Technical Specifications “requires that the appearance quality, damp -resistant friction color, soap -resistant coloring fastness, and hair ball -up projects meet the explicit product standard requirements.

Consumer

Prefer to choose all cotton -made underwear

It is not suitable to blindly pursue the thickness of the underwear fabric

The Beijing Consumers Association reminds that when buying underwear online, consumers should try to choose a full -sized product. If you need to ensure a good warmth effect, it is recommended to buy products that indicate that the product standard is FZ/T 73022. When buying, you can refer to the comparative test of the Beijing Consumers Association underwear products that meet the standard sample summary table.

When consumers buy underwear, they can choose all cotton -made underwear. Because underwear has been in contact with the body for a long time, some non -cotton -made underwear can easily cause sensitive skin to cause allergies. If you use all cotton, this chance will be reduced a lot, and the cotton underwear is soft and breathable. When purchasing, consumers can comprehensively measure the relationship between the quality of the unit area and breathability and thermal insulation rate according to the results of the comparative test results of the Beijing Consumers Association. Do not blindly pursue the weight of the fabric.

In addition, the underwear is close to the skin, and the color of the underwear is relatively poor. The color of the color is relatively poor. The color of consumers should choose the underwear. Underwear should avoid being too tight, otherwise it will cause the original body curve to be traces, and it is not conducive to the blood circulation of the body.
