This comparative test sample was randomly purchased from the Shenshi and online shopping platform from the Shenshi Association, including 20 in the store, 20 online shopping platforms, and the purchase unit price from 22 yuan to 1380 yuan. , Etc.

Test according to national standards, product description of the sample, the fiber content, the air permeability, pilling, heat rate, mass per unit area, pH, formaldehyde content, water fastness, perspiration fastness acid, alkali perspiration Testing of color fastness, dried friction fastness. The test results are only responsible for the purchased sample.

After testing, 34 samples in the 40 samples of this comparative trial reached the statement of the standard, and 6 samples did not meet the relevant standard requirements, mainly in the product instructions, fiber content, breathable and other projects have problems.

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

Product instructions

Junior sample implementation standard is incorrect

Product use instructions are the most intuitive methods of communicating with merchandise, basic performance, characteristics such as consumers, usually conveyed in the form of manual, label, durability identification. In this trial, 40 samples have 5 sample products instructions that do not meet the standard requirements, including the health, the magic suit, the financial bird, the squad, and the satellite morning and other five brands, mainly the name of the unmarked manufacturer. And addresses, not labeled product names, the implementation standard label is incorrect, and the maintenance method of the tag and the durability label is inconsistent.

Among them, the sales unit price is 168 yuan, and the mass of the health of the batch / item number 88JQ38 is incorrect. Sales unit price of 35 yuan, the batch number / item number 1627 Deline sample, its durability label did not label the product number or specifications, maintenance methods, fiber components and content.

Fiber content

Yu Zhaolin sample actual polyester fiber content is below the promising value

Fiber content is one of the important quality indicators of textile products. In this trial, only Yu Zhaolin’s underwear sample fiber content does not meet national standards, mainly reflected in its fiber-content deviation exceeds standard permission range.

From the experimental results, the sales unit price of 62 yuan, Yu Zhaolin sample with YH406J2, indicating that the underlying polyester fiber content of the inscribed is 98 ± 5, but the measured value is 89.6, which is lower than the promising value.

Breathable

The gas permeability of the financial bird sample is lower than the standard requirements

In addition to keeping warming, it is best to have good breathable performance. Otherwise, the moisture of the skin cannot be effectively excluded, and will slowly condense into water beads, gather between the skin surface and the clothes, produce local overheating and wet adhesive Uncomfortable feelings. FZ / T 73022-2012 “Knitting Warm Underwear” requires a gas permeability ≥180mm / s, in this comparative trial, indicating that the standard sample has 4 models of Arctic velvet, seven wolves, Antarctic, and financial birds. After testing, the gas permeability of financial birds did not reach standard requirements, only 109.7 mm / s.

Rising ball

All of the highly shown product standard requirements

The rising rainders have always been the hot problem of consumers complaints. In general, the ball is caused by friction of the surface of the fabric, and the fibers are wrapped together into the shape of the ball. The rapid ball affects the performance of the consumer. Among the 40 samples of this test, 26 samples of the stated standards were launched, tested, and these 26 samples of the raised balls can meet the product standard requirements of their tags.

Insulation rate

Underwear is not a fabric

The better the insulation performance is

The insulation rate refers to the ratio of warm energy. Borrow the thermal resistance of the detection fabric to compare the temperature of the sample, the higher the value, the better the warmth effect. FZ / T 73022-2012 “Knitting Warm Underwear” standard clearly requires insulation rate ≥ 30%, this test sample, Arctic velvet, seven wolves, Antarctic, financial Chinese bird these 4 product samples express this standard. Tested, these four samples of insulation can meet the standard requirements of knit warm underwear.

It is understood that consumers generally believe that the weighted clothing is widely considered, the better the weight of the clothes, which involves the quality of the unit area of ​​underwear. Unit area quality refers to a gram of grams of weight per square meter fabric, an important technical indicator of knitted fabrics. According to the test results of 40 samples in this comparative trial, the sample unit area is from 122.2g / m2 to 422.1g / m2, and the quality of breathable and unit area is not a relative relationship, and the insulation rate and unit area are not Proper relationship, the thickness of underwear fabric is not large.

In addition, it is tested, pH, formaldehyde content, water resistance, freezing resistance, freezorine powder fastness, and all samples of durable friction fastness, all samples meet national mandatory standards GB 18401-2010 ” The basic safety technical specifications of the national textile products requires, the appearance quality, the wet rubbing fastness, soap-resistant fastness, and the raised ball items meet the express product standard requirements.

Consumption tips

Priority to choose cotton underwear

It is not appropriate to blindly pursue the thickness of underwear fabrics

Beijing Consumers Association suggests that consumers online shopping in underwear, try to give priority to the goods that express the complete identification, if you need to ensure a good warm effect, it is recommended to purchase the product standard for FZ / T 73022. When you purchase, you can refer to Beijing Municipal Consumers Underwear Product Comparison Test Comply with Standard Sample Summary Table.

When consumers buy underwear, they can prefer cotton underwear. Because underwear has long been in contact with your body, some non-cotton underwear is easily allergic to sensitive skin. If you use cotton, this price will be much reduced, and cotton underwear is soft and breathable. Consumers can compare the test results according to the Beijing Municipal Consumers Association, combined with the relationship between the mass quality and the gasking rate and the insulation rate, and do not blindly pursue the thickness of the fabric.

In addition, underwear is close to the skin, the color dense underwear, the color fastness is relatively poor, and the color of the consumer chooses the color of the underwear as shallow and color. Underwear should avoid being too tight, otherwise it will cause the original body curve to be traced, which is also not conducive to the blood circulation of the body.
