90% Health Care Underwear Is Not Effective In Health Care.

The concepts such as "negative ion", "far infrared", "medical magnetic disc" and "Chinese Herbal Medicine Aromatherapy" are used as a modifier before the term "underwear". An ordinary underwear is immediately called the "functional underwear" combining modern biology, ergonomics, mechanics, medicine, cosmetology, fiber science and knitting.

During the Spring Festival, this kind of functional underwear has also become a popular gift, selling well in shopping malls and Internet.

Fu Guangwei, deputy director of China Textile Information Center, said that although there are industrial codes for health care underwear in principle and inspection standards, but lack of management, lack of standards, uneven product quality and level of technology, exaggerated publicity and confusion in the price system, it is difficult to define the number of active health care functions on the human body. At present, all the magical functions of 90% of the health care lingerie on the market are basically invalid.

There are no production standards for health underwear, only industry standards and association standards.

As early as July 2006, functional textiles were first released by the China Health Care Association and the China Association for Standardization (CAS115-2005).

In 2009, the Chinese Health Association laid down the regulations for health care functional textiles (including health care underwear), and reiterated the definition and functional principles of functional textiles.

According to the "health care functional textiles CAS115-2005" standard, health care functional textiles refer to "a kind of textiles that have functions of pmitting far-infrared rays, producing magnetic field functions, antibacterial functions, and so on, aiming at regulating and improving body functions, not treating diseases, and having no toxic and side effects on the human body."

Over the past two years, more and more pluralistic functionality.

Constantly emerging, the existing standards are also faced with revision and improvement.

No standard production, lag in standard setting and testing methods, technical requirements, market access and so on are the "short boards" of health care underwear and the entire textile industry.

It is understood that the health care underwear sold on the market has the most common functions of far infrared, negative ion, magnetic therapy, antibacterial, electromagnetic radiation, negative ions, antithrombotic and anti varicose functions. But so far, our country has only set standards for far-infrared function, magnetic function, antibacterial function, and other functional standards such as negative ions are still draft or blank.

"So far, there is no production standard for health underwear, but only the industry standard issued by the Ministry of industry for testing far-infrared textiles and the standards of the association of health associations.

Inspection is not mandatory, and it is often checked only.

The general test is a sample, not a mandatory act. "

Yang Ping, deputy director of China Textile Information Center, said.

It is often the manufacturer to inspect a piece of cloth, but it is difficult to judge the actual effect of the "health care function" because of various factors, such as the production and garment links, including the subsequent washing after consumption.

The technical level and material quality of manufacturers are uneven, resulting in the market health underwear is difficult to be worthy of the name.

dispute

The evaluation of health function can not be quantified.

But the effectiveness of health care underwear and health care textiles has always been controversial.

Specifically to the health underwear, with magnetic therapy function, far infrared function underwear, "in a certain range of human body has certain advantages, but whether there is radiation harm to the human body, has not been conclusive."

Yang Ping said this is a controversial issue.

Yang Ping said that although there are physical and chemical tests and biological tests, the function evaluation of the negative ion functional health underwear is still not known and there is no fixed test method. Different detection methods are often far from the same product test results, which also has some opportunities to promote some negative ion functional health care clothing.

There are many factors that can affect the size of negative ions in life. The amount of negative ions released by rubbing cloth and rubbing cloth is different. In daily life, the friction between cloth and cloth, the friction between cloth and body can produce many negative ions.

Whether this kind of health function still exists after washing clothes is not enough to quantify.

At the same time, experts stressed that "adding ingredients" does not mean that a large amount of health care function is good, does not mean that this is qualified health care underwear.

It is a question mark if the large magnetic disc and the excessive amount of infrared rays are good or bad for the human body.

Truth about health care underwear

The theory is feasible, and is limited by technology and material quality.

"Pearl powder underwear", "milk underwear", "aloe underwear" and other high-tech packaging underwear function propaganda is very eye catching.

"From the technical point of view, the possibility of containing amino acids and vitamins in fabric fibers is very small. Although there is a theoretical way to add pearl powder or vitamin containing particles into clothing, the technical limitations are very high, the quality requirements for the materials are also very high, and there will be strict requirements for the use of them and the long-term cost effectiveness."

An industry expert, who declined to be named, said.

"The aroma of some underwear comes from the finishing microencapsulation technology. The microcapsule will release the fragrance slowly, but whether it is negative ions or amino acids, vitamins, etc., if it is finishing, its washing resistance is weak.

However, if the negative ion functional underwear is made from spinneret solution technology, the durability will be stronger, and the function will not be reduced after washing.

But this puts forward higher requirements for technology and cost. "

Yang Ping analysis said that the high cost makes the enterprise dare not easily set foot in, and the efficiency is greatly reduced.

Such as soybean protein fiber, this plant fiber, but according to the relevant provisions, only soybean protein fiber content of more than 40%, its products have the corresponding function, but at present, many of the market health care underwear soybean fiber content is below 30%.

The quality of materials and the level of technical application are the important reasons for the current situation of health underwear, which is "beautiful in principle and hard to achieve in reality".

Material itself and added ingredients determine the size of health care function.

Although the Chinese Health Association has health care functional textiles (including

For example, the far infrared function and magnetic health care underwear, for the CAS115-2005 standard, the "far-infrared function" and "magnetic function" logo will be issued. For example, the publicity of "far-infrared function" is limited to "having the function of keeping warm and improving the temperature of the wearing parts, such as improving the cold condition of hands and feet". However, the advertisement of a far infrared health care underwear brand is full of "auxiliary treatment of diseases such as muscle and muscle pain, tendinitis, bedsore and so on", so as to prevent such functions as rheumatism arthritis, hyperosteogeny, periarthritis of shoulder and cervical spondylosis. These are forbidden to use: "no exaggeration for treatment of diseases and so on." it is stipulated.

In fact, such as the wavelength of far-infrared rays and the extent of magnetic intensity, there are strict mechanisms to define the quantity and distribution of magnets. It is reasonable and scientific to design the quantity and distribution of magnets, such as "extremely weak and hyperthermia patients."

Whether it is far-infrared or negative ions, it is in the production process, in the production of specific fabric fiber to add a specific "additive", or in the finishing process into the "additive".

The determinants of the size of the health function are the amount of the material itself and the added ingredient.

Hot questions and answers

Does Q wear this kind of airtight and tightly attached health care underwear for a long time? Does it cause damage to the skin? Or can other so-called health functions cause harm to the human body?

Yang Ping: I think a very important function of clothing is comfort. Consumers need to wear functional clothing that is comfortable and can meet their various needs.

But whether it's comfortable or not, I went through ten years ago, wearing a magnetic body, and I didn't feel sick or useful.

From the perspective of clothing hygiene, the force on the skin of the unit area is called clothing pressure. From the perspective of human protection, sports efficiency and aesthetic point of view, a certain degree of clothing oppression is beneficial, but excessive oppression can cause human bone deformation, visceral displacement and respiratory restriction.

There are some abdominal breech pants with low elastic elongation and serious clothing pressure on the human body. Whether it will cause harm to the human body is still uncertain.

Q how can consumers choose formal health care underwear with many health care functions in many products?

Yang Ping: it's hard to say.

The existing standard is only a test standard, but in laboratory environment, it is difficult to detect its benefits to human body.

For example, far infrared functional underwear can detect far-infrared wavelengths. Theoretically, there are some theories about the promotion function of far-infrared heating on the microcirculation of human body. However, there are also controversies about what extent the wavelength does not harm human body and whether there is radiation.

For example, the effect of the size of the magnet on the human body is not proven.

I generally do not buy this kind of underwear with health care function. Consumers should not be fooled by the conceptual hype of health textiles.

Zhou Bangyong, Deputy Secretary General of China Health Care Association: December 9, 2007, the China Health Association reached the mark.

By testing and evaluating the products that are up to standard, according to the "association standard marking management regulations", it is necessary to label the sales mark so as to distinguish the good and bad products, so as to play the role of enhancing the quality and reducing the inferior quality, and safeguarding the legitimate rights of consumers and enterprises.
