Are You Still Superstitious?

T-shirts are popular among people in spring and summer.

In the market, T-shirts have many brands and different styles, and consumers are prone to have some blind areas of consumption.

In order to help consumers better fulfill their legitimate rights and interests, such as the right to know and the right to choose, the Consumer Association of Tianjin made a comparative test from April 2015 to June on the basis of the public welfare duty of the association of consumers in accordance with the law of the People's Republic of China on the protection of consumers' rights and interests.

Are the samples representative?

The relevant staff members of the Municipal Association of consumers, the samples are all municipal Consumers Association staff members and 315 consumer rights volunteers, 11 large shopping malls, exclusive stores and shopping centers in 7 administrative districts of the city, according to the actual consumption procedures of ordinary consumers, they are randomly purchased.

A total of 22 brand T-shirts were purchased, ranging from 149 yuan to 2691 yuan per sample, and the "product grades" of the T-shirt samples were classified as "first-class goods" and "qualified products"; 5 brand T-shirts were not marked out of origin, and the rest of the T-shirts were marked out in Shanghai, Guangdong (Foshan, Guangzhou, Dongguan), Zhejiang province (Ningbo, Jiaxing), and Thailand, Vietnam, Kampuchea, Italy, Portugal and other countries and regions.

In accordance with the requirements of the general principles of consumer goods and related services, the comparative test was commissioned by the national quality supervision and Inspection Center for knitted products, GB/T16759-2008.

In accordance with GB18401-2010, "national textile product basic safety technical specification", GB5296.4-2012 "consumer goods instructions for use of textiles and clothing", GB/T29862-2013 "textile fiber content logo", GB/T22849-2009 "knitted T-shirt", FZ/T73020-2012 "knitted casual wear", FZ/T43015-2011 "silk knitted garment", FZ/T73043-2012 "knitted shirt", GB/T21655.1-2009 "textile moisture absorption and quick drying evaluation" standard comparison test.

20 items, including product identification, color fastness, fiber content, formaldehyde, pH value, decomposable aromatic amine dye, pilling and bursting strength, were selected.

In addition to testing some items that are prone to quality problems, the T-shirt comparison test focuses on the comparison of the actual performances such as hygroscopicity and quick drying. Five indexes, such as water absorption, drip diffusion time, core suction height, evaporation rate and moisture permeability, are set up to provide reference for consumers to choose and buy.

Some big brands are "not reliable".

Compared with the results of the comparative test of children's skin care products just completed by the Consumer Association last month, this T-shirt comparison test shows the overall quality of T-shirt products needs to be improved, especially some famous brand T-shirts, which are "shot" in the comparative test, and the quality is not directly proportional to the price.

In this comparative test, samples of 22 brand T-shirts were tested, involving more than 800 specific indicators of 20 types of inspection items.

"In these samples, the 9 brands of T-shirts, which are the trademarks of EmporioArmani, Boboli, Zegna, PRADA, ANDREWMACKENZIE, URBANRENEWAL, Wan Xingwei, Miguel and BUSEN, are found to be non compatible with standard requirements, such as fastness to light fastness, fiber content, color fastness to rubbing, product identification, etc., and do not meet the relevant standard requirements, accounting for 40.91% of the total number of samples.

Relevant staff of the City Association of consumers, including the "Hisense Plaza" sales, the nominal production enterprise is Shanghai Chong Kun Industrial Co., Ltd., the trademark "ANDREW MACKENZIE" brand T-shirt samples, the purchase price of 2691 yuan / piece, is the highest price of the sample, but was detected "fiber content, dry friction color fastness, wet rubbing color fastness" 3 project indicators do not meet the standard.

Some of the international brands that consumers are familiar with also have indicators that are not up to standard.

Product identification problem is more prominent.

Product identification is provided by the producer, indicating the information, such as the name, place of origin, producer name, address, product quality, duration and instructions.

The identification of products is the quality information of the producers of the products to the sellers and purchasers of the products, to help them understand the composition, quality and the standards of the products, explain the use and maintenance conditions of the products, and play a role in introducing products and guiding consumption.

According to the relevant regulations, textile and clothing labels should contain the following contents: product quality certificate, product name, factory name, factory site, trademark, grade, fiber composition and content, clothing type, washing instructions, etc.

The nominal value of fiber content in some samples is not accurate.

Fiber content, also known as fiber content, is the main quality index of textile products. The quality of raw materials is one of the important factors that determine the value of products. It is also the main content of genuine goods and plays an important role in guiding consumers to buy.

The percentage of fiber content should be clearly and correctly marked in the fabric, lining and filler of each product.

Some samples "fade", affecting human health.

Color fastness, also known as color fastness and dyeing fastness, refers to the degree of fading in the course of dyeing and finishing, which is subjected to external factors (extrusion, friction, water washing, rain, exposure, illumination, seawater immersion, saliva impregnation, water stains, sweat stains, etc.) and is an important indicator of fabric.

Popularly speaking, "color fastness" is the "fading" of ordinary citizens.

Color fastness is listed as an important safety index in the national basic safety technical specification for textile products.

Once the clothes with poor color fastness fade or fade in the process of wearing or washing, they may cause harmful substances to infiltrate into the skin and affect human health.

For example, decomposable aromatic amine dyes, also known as carcinogenic aromatic amines, are commonly used as "banned azo dyes".

After making clothes, it is not only insoluble in water and colorless and tasteless, but can not be discern from the appearance of textiles. Only by technical inspection can it be found and can not be eliminated. This dye will affect human health after contacting with human skin.

Therefore, color fastness can be used as an important indicator of whether clothes are reliable.

Therefore, this comparative test has tested 8 indicators: water fastness, color fastness to perspiration, color fastness to rubbing, color fastness to dry rubbing, color fastness to rubbing, color fastness to soaping, color fastness to printing, fastness to light, fastness to light and sweat.

Moisture absorption and quick drying performance are not ideal.

Hygroscopicity

The ability to absorb sweat.

Especially in summer after outdoor walking or sweating after exercise, people hope that T-shirts can absorb sweat quickly, keep the skin relatively dry, feel comfortable and cool.

Fast drying is faster drying. It does not absorb sweat, but pfers sweat quickly to the surface of clothes, evaporating sweat through air circulation, so as to achieve the purpose of quick drying.

If the fabric absorbs sweat, it can not dry in time, it will be uncomfortable to stick on the body. If you encounter cold wind, you will feel cold and damp. You may catch cold because of losing temperature.

Moisture absorption and quick drying are very important for the comfort of summer wear. If sweat is not evaporated quickly and dry, it will affect the comfort and beauty of T-shirts.

There is no national standard for hygroscopic and quick drying. Therefore, this test has referred to the requirements of the first part of the "evaluation of moisture absorption and dryness of textiles: the single combination test method" (GB/T21655.1-2008). The test results show that the samples are fast dry, but the moisture absorption is slightly worse.

Dan Xuelei, deputy director of the national quality supervision and inspection center of knitted products.

In this comparative test, the moisture absorption and quick drying function were divided into 5 indexes, namely water absorption, drip diffusion time, core suction height, evaporation rate and moisture permeability.

The first 3 items were characterized by hygroscopicity, which represented the sorption capacity of T-shirts to liquid sweat. The latter 2 were fast drying indexes, which represented the fast drying properties of T-shirts under liquid sweat condition.

Dan Xuelei said, water absorption, that is, the quality of fabric saturated absorption of water relative to the weight percentage of the fabric itself, the larger the value, the better the water absorption.

Drip diffusion time refers to the speed of diffusion of a certain mass of water droplets on the fabric, and the faster the diffusion rate, the better the function of quick drying.

The core suction height refers to the climbing distance of the unit time water on the fabric, the larger the better the moisture absorption of the clothing.

Evaporation rate is the quality of water evaporated by unit time. The higher the index is, the faster the dry clothes are.

The moisture content is the volume of water vapor per unit area and the larger the index, the better.

Expert weapon: does T-shirt purchase the attention?

"There are many T-shirts with moisture absorption and quick drying function on the market. How should we buy them? What are the dangers of T-shirts' discoloration?" with these questions, reporters interviewed the relevant consumers of the city consumers' Association and the single student Lei, who bought the T-shirts for consumers in the summer.

Q: how to buy T-Shirts with moisture absorption and quick drying?

Answer: when buying a T-shirt with moisture absorption and quick drying, consumers can drop a drop of water on their clothes to see whether it spreads or spreads quickly.

Reference can also be made to the fiber composition of the tag. Generally speaking, the moisture absorbency of the traditional polyester, acrylic, nylon and other fabrics is poor, and the hygroscopicity of cotton, hemp, modle, Le cel, Tencel and other fabrics is better.

Q: does T-shirt discoloration do harm to humans? How can we avoid buying T-shirts that are fading?

Answer: fading is the color fastness mentioned in this test report.

It is easy to sweat in summer. Dyed clothes will enter the body through sweat and skin. Some dyes contain carcinogenic substances and heavy metal ions. When these harmful substances accumulate to a certain level in the body, they will affect their health and harm to infants and young children.

Coloured T-shirts can be rubbed on the fabric with wet wipes or napkins when buying, so as to check whether they are obviously fading. It is not recommended to buy T-Shirts with obvious fading.

Q: the label of T-shirt is marked with product specifications S, M and L. Is this qualified?

Answer: it is wrong to mark only S, M and L.

Our country has strict requirements for product specifications. The general specifications are divided into two categories, one is height bust, height waist circumference and body shape. A is the ordinary body, B is slightly fatter, C is fatter, Y is model body, such as 160/84A, the other is height and circumference, and "circumference" refers to the circumference of clothing, such as 160/105.

In addition, special products have special marking methods, such as bra bottom products and bra cups.

Manufacturers and consumers should note that only S, M and L are not qualified, but it is also possible to write S, M and L on the premise of marking the requirements.

Q: can new t-shirts be worn directly?

Answer: newly bought

Shirts are best washed once they are worn.
