On December 30, the Tianjin Consumer Association released the comparative test results of plush thermal underwear. A total of 29 samples were involved in this comparative test, and the formaldehyde content, decomposable carcinogenic aromatic amine dyes, pH value, and pilling detection items of all samples met the standards.
The 29 samples of this comparative test were randomly purchased by staff of Tianjin Consumer Association, 3.15 volunteers and inspection agency personnel in shopping malls, online e-commerce platforms, Douyin and Kuaishou live broadcast platforms in Tianjin’s jurisdiction, with unit prices ranging from 29.9 yuan to 288 yuan.
The comparative test is entrusted to “Tianfang Standard Testing and Certification Co., Ltd.” for testing. According to FZ/T 73022-2012 “Knitted Thermal Underwear”, the fiber content, formaldehyde content, pH value, decomposable carcinogenic aromatic amine dyes, pilling, color fastness to soap, color fastness to perspiration, color fastness to rubbing, heat preservation rate, air permeability and other items of the flocker thermal underwear products were tested, and the color staining degree of the sample was tested with reference to clause 6.1.11 of FZ/T 73020-2019 “Knitted Casual Clothing”.
According to the information marked on the sample, the Tianjin Consumer Association gave feedback to the manufacturer/entrusting party of the sample nominal in the form of an official letter. The results of this comparative test are only responsible for the sample.
In terms of explicit implementation standards, 21 samples implement the “knitted thermal underwear” standard or enterprise standard that evaluates functional indicators such as “heat preservation rate” and “air permeability”. The test results showed that the quality indicators of 7 samples did not meet the requirements of the explicit standards (see Table 1 for details).
The nominal trademarks purchased from Tianjin Zhongyuan Department Store (Hualian Store) are “Luwang Lianxue” double-layer camel down women’s pants and “A&B” ultra-soft warm men’s pants, the “Yufeng women’s thermal pants” purchased from China Resources Vanguard Tianjin Xiqing Road store, and the nominal trademark “Arctic Velvet” gold comfort velvet thermal underwear purchased from “Vipshop (self-operated)” A total of 4 samples did not meet the fiber content; The nominal trademark purchased from Tianjin Xiyue Hui Shopping Center is “
“The breathability rate of women’s thermal clothing does not match; The nominal trademark purchased from “Douyin” was “Junfei Huage” underwear, and the nominal trademark purchased from Ouyada Commercial Plaza (Tianjin Hongqiao store) was “Shanshan”, and the fiber content and air permeability of 2 samples were not met.
It is worth noting that 8 of the 29 samples claimed “fleece” and “warmth” in the sales promotion, but did not implement the FZ/T 73022-2012 “knitted thermal underwear” standard, and its explicit implementation standards did not assess the key indicators of thermal underwear such as thermal insulation rate and breathability rate. All 8 samples were sold online (see Table 2 for details). The test results showed:
The nominal trademark purchased from “Suning Tesco” is “TONLION Tanglion” women’s non-marking bra vest sample with a measured thermal insulation rate of 21.87%, and the measured air permeability rate is 125mm/s, which is lower than the provisions of the “knitted thermal underwear” standard that the insulation rate should be ≥ 30% and the air permeability rate should be ≥ 180mm/s (see Table 3 for details); The nominal trademark purchased from “Pinduoduo” is the sample of “Fenteng” underwear set (no sample name), the nominal trademark purchased from “Jingdong Mall” is “Yu Zhaolin” thermal underwear and “Kangaroo” men’s wool crewneck thermal set samples The measured air permeability rates are 89.2mm/s, 111mm/s and 141mm/s, respectively, which is lower than the “knitted thermal underwear” standard stipulates that the air permeability should be ≥ 180mm/s (see Table 4 for details), and the measured thermal insulation rate meets the standard of “knitted thermal underwear”.
The nominal trademark “Modair” thermal underwear sample purchased from “Jingdong Mall” does not meet the explicit implementation standards (see Table 5 for details), and the thermal insulation rate and air permeability rate are measured in line with the standards of “knitted thermal underwear”; The nominal trademark purchased from “Vipshop (self-operated)” is “Jielia” women’s warm suit, the nominal trademark purchased from “Tmall” is “Camel” women’s plush suit and “Aurora Ice Bear” super soft double-sided velvet vest sample, the fiber content, heat preservation rate and air permeability rate measured values meet the standard of “knitted thermal underwear” (see Table 6 for details).
Relevant experts believe that the heat preservation rate and breathability rate are the key functional indicators of thermal underwear, and they are also important indicators that are closely related to consumers, which directly affect the comfort of wearing. It is precisely for this reason that the FZ/T 73022-2012 “knitted thermal underwear” standard stipulates these two indicators. If an operator claims “fleece” and “warmth” in its sales promotion, but implements the standards that do not assess these two indicators, it is suspected of avoiding risks or misleading consumers to buy.
The Tianjin Consumer Association believes that this relatively “low-key” phenomenon in the selection of implementation standards exists to a certain extent in the field of clothing, especially in the field of functional clothing, which should attract the attention of relevant parties. For business operators, they should actively perform the legal obligations of the person first responsible for the protection of consumer rights and interests, abide by the principle of good faith, standardize the labeling and sales publicity of sales products, strictly enforce product quality standards, accept social supervision, and ensure the legitimate rights and interests of consumers.
At the same time, the Tianjin Consumer Association reminds consumers to pay attention to the following points when purchasing plush thermal underwear:
First, consumers should try to buy products from regular manufacturers in large shopping malls, supermarkets, and specialty stores, or goods from online flagship stores, and the products of well-known manufacturers have a good guarantee in terms of product quality, so as to avoid purchasing “three no products”.
Second, consumers should pay attention to whether the product advertising and product label labeling standards are consistent when purchasing products, and try to choose products that implement the FZ/T 73022 “knitted thermal underwear” standard.
Third, in the process of purchasing, pay attention to check whether there is a Chinese mark on the thermal underwear product, whether it is marked with the factory name, factory address, fiber composition and content, product safety category, maintenance and washing method, product quality level description and other information; Check whether the thermal underwear product has pungent odors or odors such as musty smell, gasoline smell, kerosene smell, fishy smell, etc., and if there is a recommendation, do not buy; Observe the pile of the fleece thermal underwear, the velvet of good thermal underwear is delicate and evenly distributed, while the poor one is very coarse, and the thickness is uneven and strip-like; Turn the inner lint of the thermal underwear in reverse and touch it with your hand, good thermal underwear is very soft, elastic and very good; And poor thermal underwear is hard to the touch and lacks elasticity; Thermal underwear is usually not try-on, but you can rub the inner velvet part close to the inside of the forearm to experience whether there is a rough, prickly feeling. When choosing, you can use your hand to pull the hair of the inner pile, if it falls off, it means that the quality is poor, and it is likely to fall off in the future.
Fourth, consumers should choose well-fitted plush thermal underwear, which is close but not tight. Thermal underwear that is too tight can compress the subcutaneous blood vessels and hinder its own blood circulation; Too loose thermal underwear can not fit the skin resulting in ventilation, can not achieve the ideal warmth effect, and loose thermal underwear is also easy to form wrinkles, affecting the beauty.
Fifth, it is recommended that consumers wash before wearing, washing before wearing can not only neutralize the PH value of the fabric, but also reduce the floating color and floating hair of the dye, which is conducive to the health of consumers.
Sixth, consumers are advised to keep invoices and other relevant consumption vouchers, and in case of disputes, they can protect their legitimate rights and interests through shopping vouchers.
