Market Watch: thermal underwear “high tech” is mostly a promotional gimmick
By admin | Filed in Underwear Introduction | No comments yet.HCClothing onlineWith the temperatures drop, the businesses in order to meet the needs of consumers, the introduction of a variety of thermal underwear. Microfiber, 37 ° C constant temperature ultra-thin warm “,” add a high-tech polymer, “Joining the infrared emission of ceramic” … now is entering the winter season is very hot, thermal underwear, thermal underwear manufacturers almost have declared a “high tech” fabrics, the price of a set of underwear but never four $ 50 thousand dollars, people confused and believe it or not, true or false, numerous consumer doubts, I do not know how to choose purchase. So, thermal underwear really is the use of hi-tech do?
Uncover the veil of “high tech”
A wide range of thermal underwear is really high-tech product? In fact, there is so much underwear fabric, some of them just using product names instead of the name of raw materials, does not belong to high-tech, new inventions. Used in the textile, chemical fiber is with 28 kinds of commonly used acrylic, polyester, spandex, modal fiber indicated in the business of the ingredients on the label name exceeds the 28 kinds of outside, you may play with a new term. Knowledge of chemistry, we know that, in fact, the so-called “high tech” is not so iffy. Thermal underwear material is nothing less than natural fibers, synthetic fibers and man-made fibers three categories. “Card” but manufacturers from concept to fabric alias. “Warm card” Thermal Card “is actually acrylic, the” magic card “is a flexible spandex,” Se Weika “is polyester, the” Lycra “is the product of artificial elastic fiber” spandex “registered trade name.
Really nano thermal underwear? Nanomaterials in recent years, highly respected, but be able to say exactly the characteristics of the concept is fresh, few. At present, the identification of nano-products need to go through complex testing, not only depends on the change of its material particle size below 100 nm, depends on its optical, electrical, mechanical and other properties whether the nano-features of the market sales many “nano underwear” and whether all this strict identification is worthy of suspicion. The Suzhou Miyama subsidiary general manager, Zhang Ronglong, said: “Many products are labeled” green “,” far infrared “,” nano anti-bacterial, these features of the new function of “the beauty of moistening” or even “Vitamin underwear” only party Night Tan, infrared nano-and those who claim to play warm the role of underwear with the function of “far infrared” is even harder to make the identification of the human body, including any substance with the ability of the scattering of far-infrared, a warm underwear whether the effect stems from the role of the far infrared is difficult to find the exact basis. ”
It is understood that the cost of production of a thermal underwear just above 0.5 times the ordinary underwear and once labeled a novel concept of identity, thermal underwear will be worth increased sharply, sales prices generally doubled on the turn. Therefore, these “high tech” is how is it, they probably also at a loss to explain not why.
Divided into three main material of the thermal underwear, the first natural fiber such as cotton fiber, soybean fiber, wool, etc., through the processing of natural flora and fauna; The second is a modified fiber, such as milk protein fiber by adding the chemical composition on the basis of the natural fiber synthesis; third purification fiber, the fiber extracted from oil and then processed into raw materials.
Opened the veil of thermal underwear “disease prevention fitness
Selling thermal underwear stores over the past month the business is booming, and the vagaries of various studies on the thermal properties described. Some thermal underwear called Body skin care, sterilization and deodorization. Recently, a lithium rechargeable underwear products, priced as high as five hundred or so more expensive than ordinary underwear in the supermarket more than doubled. Lithium batteries and cell phones can still be removed, has issued a hot clothes T-shirt back, cervical, and pants below the knee, the duration of 4 hours to 8 hours. “Business introduction, this underwear using a composite heating fiber is high new technology products, not only warm, but also disease prevention fitness. But we search to know that lithium is a class of anode materials for lithium metal or lithium alloy battery, the use of non-aqueous electrolyte solution. Jiulong Town, Jiaozhou, Shandong Province Textile Machinery and technical personnel Kuanghua Chun said in an interview: “Because of the chemical properties of lithium metal is very lively, making lithium metal processing, storage, use, very high demands on the environment., Lithium long-term has not been applied now lithium has become the mainstream in many parts of the supply heat underwear battery, battery electric underwear, thermal underwear lithium battery. However, the temperature of the lithium battery life also have a large impact on the environment below freezing may make lithium batteries in electronic products instantly open burned, and in which there may be certain degree of risk, so underwear really fitted with lithium batteries warm function, underwear, disease prevention and health is not known. ”
Fiber inspection bodies from Jinan City, the author noted that the current industry standards for thermal underwear reference to the National Development and Reform Commission approved the “knitted thermal underwear industry standard. The standard specifies thermal underwear on the outside of the package shall be marked “warmth rate” and “Unit weight warmth rate”, and the warmth rate greater than or equal to 30%, the formaldehyde content should be below 75 mg per kg.
Insulation is how is it?
A lot of underwear also marked rate of insulation, but insulation how to identify it? Knitted thermal underwear industry standard, known as thermal underwear, its insulation rate must be at least 30%, permeability, water vapor permeability must also comply with the relevant industry standards. If you find that there is no insulation rate data, thermal underwear directly with vendors to obtain the test report to view. Optimal thermal underwear First Grade must be done, insulation ≥ 45%, the ventilation rate (mm / s) ≥ 180 and <250> 500, ≤ 1000 the two regions within the water vapor transmission rate (g / m2.d) ≥ 2500.
The new standard from the thermal features of the most basic provisions of thermal underwear is made no matter what kind of warm materials, warmth rate “and” unit weight warmth rate “shall be marked on the packaging of its finished products. Nominal “thermal underwear” products, the thermal rate of not less than 30%. However, the standard recommended standards only, rather than mandatory standards, marked or not is still the voluntary act of the production enterprises.
Therefore, in the purchase of thermal underwear, consumers should be keeping them warm in the first place, must not blind pursuit of novelty effect. Also hope that the relevant enterprises to strengthen self-discipline, not by the novel concept of speculation, and truly to the quality.
Market research: thermal underwear “high tech” a gimmick
The reporter visited the learned, in fact, these “high tech” products, ingredients or less the same, the basic traditional materials are cotton, acrylic, spandex, polyester, and man-made fibers. The experts have warned that the purchase of thermal underwear do not be fooled. The new term of the new nano “thermal underwear”, “high-tech fibers” and “far infrared”, some of the sales staff and even admits that they do not know why the matter. “In fact, we are not sure these tricks in the end what is the principle, anyway, the purchase price is high, our selling price. Qingdao City, one to sell thermal underwear boss told reporters.
Zhang Xun, retail marketing consultant of the International Wool Secretariat, said in an interview: “” warm edge card, thermal card is acrylic “Se Weika” is polyester, the “magic card” flexible spandex Lycra but DuPont for the production of an artificial elastic fiber – spandex registered trademark name. ”
Reporters on these “high tech” materials interview with Mr. Zhang of Shandong Province Quality Supervision Bureau staff. Mr. Zhang said, in fact, the so-called “high tech” is not so iffy. Thermal underwear material is nothing less than natural fibers, synthetic fibers and man-made fibers three categories.
Links: How to choose winter thermal underwear
A selected brand, look at the word of mouth. Generally well-known production of thermal underwear, from raw materials selection, spinning, weaving, dyeing, composite, sewing factory inspection of all aspects of the process are required to strictly the product of warmth, breathability and flexibility the indicators are in line with the standards. Therefore, consumers buy thermal underwear, first to see the price, at the same time look at the function, should pay attention to choose the strength, excellent brand, the products of reputable companies to ensure that purchase no worries. Also you can pay attention to the reputation of the product, the people by word of mouth is often the voice of experience, which can be used as a standard of reference.
(2) test flexibility. The new generation of thermal underwear pay more attention to the development of new products of the contemporary aesthetic of the body curve, a major breakthrough in thermal underwear with excellent elasticity. Underwear in the fabric and the end of compound added Lycra, lined with core high-flexible polymers, although the price is higher than ordinary products, but worn, good personal sense, there is no bloated feeling, the joint of activities is also very comfortable. Also note that the choice of underwear do not choose too tight underwear, tight underwear will affect the body the blood circulation. Especially women, do not select tight underwear because you want the significant body, thereby affecting the health of penny wise and pound foolish.
3 by hand. High-quality microfiber underwear in the middle insulating layer (diameter less than 1.2 silk) weaving, garments, both soft comfortable to have good thermal properties, hand kneading, supple feel, and no foreign body sensation. Intermediates comb composite technology is more advanced, and the unity of the garment surface and intermediate, wear and better performance.
To sum up, consumers buy underwear, you should proceed from reality, not blind to listen to high-tech, multi-functional. First of all, be rational to identify a variety of advertising, do not blindly believe in the so-called “high tech” concept, because some of the new term how those features claimed by the manufacturer, it is difficult to guarantee; Secondly, we must focus to view the content of ingredients to determine whether and labeling The consistent warmth rate is generally inversely proportional to permeability, according to individual needs, both warm and breathable thermal underwear; Third, we must focus on the thin fabric soft, flexible, feel good.
