Pressure Indicators Will Soon Be Included In Seamless Underwear Quality Evaluation System

　　 " pressure Indicators will soon be included in the seamless underwear quality evaluation system. Our reporter recently learned from Lin Guang Xing, Secretary General of the China Knitting Industry Association. With the continuous improvement of China's textile and garment quality standard system, especially under the pressure of the pressure of underwear, the knitting industry in China needs to update the standards so as to ensure healthy and rapid improvement.

"Though only in alliance standard But it is an important opportunity and declaration. He thought.

According to the reporter's understanding, many knitted underwear products are widely used in the market, so as to make use of their elastic and close to human body. However, if the human body is under a certain pressure for a long time, breathing will become difficult, and even the internal displacement, blood flow obstruction and bone deformation may occur.

　　 Standardize clothing with "pressure"質量 勢在必行

Human beings, as an organism, have limited bearing on mechanical stimulation. The clothing pressure (clothing pressure) has been studied in the academic circles. It refers to the force generated by the vertical action of clothing on the human body, usually caused by the weight of clothing or the elastic deformation of clothing.

A few years ago, when many women lost confidence in dieting, taking medicine and other weight loss methods, a new way of losing weight -- "beam (plastic)" came into being. Business promotion, as long as you wear our "plastic (underwear) underwear", you can lose weight. But then in Chongqing, there was an explosive news that women collapsed on the streets for a long time wearing body underwear and breathing difficulties.

"For ordinary women, the static ideal pressure of winter clothing is 1076 PA, the spring is 1274 PA, the summer is 1370 PPA, and the male is 20% higher than the average." Studies have shown that. However, many body or tight underwear tend to be much higher than this index. A strong pressure will accumulate the secretions of the pudendum, which can not be distributed in a damp and stuffy environment, thus stimulating vulvitis to cause vulvitis, resulting in dermatitis and bacterial reproduction caused by skin abrasion of the thighs. Retrograde infection can cause vaginitis, pelvic inflammatory disease, and urethral infection.

Experts pointed out that many of the material of underwear is generally chemical fiber, breathability is poor, and require long-term adherence to wear. It is better for women to wear less clothes. Girls in puberty stage should not wear them because wearing underwear will affect human development and blood circulation, sweat excretion, and even induce gynecologic diseases such as mammary gland hyperplasia, cysts, vaginitis and so on.

"Our products are very breathable, and there is no pressure problem. There is no need to worry about that." This reporter called the LA MIU, a Japanese underwear concept, as a consumer. It can be seen that enterprises do not recognize the existence of stress problems and their damage to the human body at all. In fact, researchers have studied the effects of clothing on the human body with different pressure during the day. The conclusion is that the higher clothing pressure during the day produces obvious fatigue, which makes the ratio of urinary adrenaline and norepinephrine significantly higher at night, indicating that the sympathetic nervous system is more excited and the heart rate is higher.

Pressure is not known to standard enterprises.

According to the reporter's understanding, rubbing fastness, color fastness to washing, fiber content, pH value, formaldehyde content and other indicators have been incorporated into China's textile quality and safety system, the relevant national standards and industry standards are clearly listed. However, insiders pointed out that "in China's clothing standards, there are no pressure indicators." It is not surprising that enterprises have no knowledge of the pressure standards.

Harbin Huayi Knitting Co., Ltd. is an old enterprise established in 1994. It produces 2 million kinds of underwear every year, and produces 25 million of its value, of which 70% of underwear products are exported to Japan. Wang Yunfeng, the product sales manager of the company, told the China fiber inspection reporter that he was not clear about the upcoming pressure standards. "Underwear of our company mainly uses soybean fiber, bamboo charcoal fiber, corn fiber, nylon, modal, colored cotton, pure cotton, Australian wool, milk fiber and bamboo fiber as fabrics. I haven't heard of underwear having pressure indicators. For us, agents and consumers don't care about the pressure of underwear.

Is it true? In fact, there are studies showing that even the most common underwear, bra, has a great influence on the human body. After studying the pressure condition of the base clothes represented by bra, researchers found that the pressure significantly reduced the activity of autonomic nervous system in women wearing bra, and the frequency of parasympathetic, thermal sympathetic sympathetic activity and vagus nerve system activity decreased significantly, even heart rate changes.

"As long as clothing, wear on the body have pressure comfort problems, even the most relaxed clothing, will also produce some pressure on the human body." Experts point out.

Stress has been widely used in sports.

In sports competition, the pressure of clothing has an important positive effect. For example, some athletes (such as gymnastics, swimming, bodybuilding, etc.) need to wear certain clothing pressure of competitive clothing, in order to improve their performance.

The shark skin swimsuit at the Beijing Olympic Games used its excellent elasticity and extensibility to effectively tighten the muscle fibers of the two muscles and thighs of Phelps and so on, so as to reduce fatigue and speed up. According to the athlete's physique, Adidas's swimming suit provides gradient pressure to the human body, that is, applying different sizes of tension at different parts of the body without affecting the body's free movement and arousing the proprioception of the human body. This gradient pressure can improve the blood microcirculation and reduce muscle tremor, and the improvement of microcirculation can help the body to use the oxygen in the blood more effectively.

Weightlifters must also wear their waist when carrying out projects. There are two reasons for this: on the one hand, with the pressure of the waist, the lumbar spine injury can be prevented, and the lumbar muscle contraction force can be enhanced. On the other hand, the energy can be condensed and the explosive force can be improved. Throwing items (discus, javelin, etc.) with single sleeve clothing can ensure the compression and support of the arm muscles.

On the other hand, according to the principles of ergonomics, wearing moderately stressful clothing (rather than without any pressure) can protect the human body in sports. For example, wearing tight leggings and corsets can reduce fatigue and improve athletic comfort during running. Clothing pressure at this time helps to reduce muscle vibration, maintain tension, reduce energy consumption and pain caused by tremor, and increase exercise endurance.

Garment pressure testing system has appeared.

According to the understanding of "China fiber inspection" reporter, at present, some enterprises have developed a test system specially designed for clothing pressure. "Our company has developed a set of clothing pressure testing system, which can effectively guide clothing designers to dress design, guide enterprises to conduct scientific production, and guide consumers to buy clothes." The director of Dongguan Dongming Instrument Co., Ltd. told China's "fiber inspection" reporter that the principle of the system is to use the human body model as a template, scientifically calculate the pressure on different parts of the body, and then send it to the computer and analyze its comfort with professional software.

According to the person in charge, clothing pressure on the human body is too large, not only affects the wearer's comfort and ease, but also has a negative effect on its work efficiency and fatigue. Clothing pressure exceeds a certain value, wearer is prone to fatigue, blood circulation obstruction and gastric ptosis.

As early as 1970s, there were cases of using pressure clothing to treat burn patients abroad. At that time, not only the finished knitted products were available for doctors to choose, but also the patient's body data could be sent to the manufacturer for customization, using CAD to design and knit the size and shape required to try it on.

During the treatment period, patients are allowed to put on elastic pressure clothes or sleeves. Regular replacement to prevent or reduce the occurrence of hypertrophic scars and reduce muscle atrophy has long been proved to be simple, effective, widely adapted and less complications.
