China'S Assault Clothing Goes To The Top Of High Technology -- Independently Developing High-Tech Waterproof Breathable Membrane.

Not long ago, this newspaper reported that the Chinese Consumers Association and the Chinese Mountaineering Association jointly organized the results of the comparative test on mountaineering clothes (outfits) at the cross country pioneer club in Beijing. This is the first time in China to compare the brand of outdoor mountaineering clothes (assault clothing), attracting many consumers' attention.

In view of the consumer's general concern about the science and technology content of the assault clothing, the reporter made an in-depth investigation and interview.

Reporters learned in the interview that the waterproof and breathable high-tech breathable breathable membrane has recently been successfully developed by outdoor enterprises in China.

Waterproof and ventilation is a contradiction.

3TO1-TEX waterproof breathable membrane

It has waterproof, breathable and windproof functions.

In an interview with reporters, Li Shi, Secretary General of the venue equipment and Equipment Committee of the State Sports General Administration's mountaineering management center, said that China's outdoor products market is a new industry which is in the breeding stage, and its development is very fast and the prospect is limitless.

In 1998, outdoor sports sprang up in Beijing, Guangzhou, Kunming and other places. In 2002, sales of mainland outdoor products exceeded 100 million yuan; in 2008, sales of outdoor products in the mainland reached 3 billion 650 million; the average annual growth rate was over 40%; it is expected to exceed the US sales in 2010 and become the world's largest outdoor consumer country.

Li Shi said that the requirement for the outfit is to focus on functional and protective functions on the basis of the general clothing function.

With the progress of science and technology, professional clothing can basically meet the requirements of ordinary consumers for waterproof and windproof. High-grade professional clothing can also meet the requirements of high moisture permeability and breathability, so that sweat can be discharged in time, and the body will keep dry.

However, both professional mountaineers and outdoor sports enthusiasts have noticed that many domestic and international brand jackets are stuffy when they dress.

Businessmen generally mark waterproof, breathable and moisture permeable indicators on clothing. In terms of physical principles, water and air permeability and moisture permeability are often a pair of contradictions, that is, the higher the waterproof index, the lower the air permeability and moisture permeability index.

Water proofing refers to the amount of liquid water passing through the fabric at 24 hours per unit. The waterproof index is generally achieved through the sealing of the fabric, but the higher the sealing, the lower the air permeability and moisture permeability.

Moisture permeability refers to the amount of water vapor per square metre of fabric passing through 24 hours under a certain temperature and humidity condition, which is generally used to measure the sweating function of fabrics.

And permeability is the gas flow through the fabric per unit time under certain pressure differential conditions.

Because the fabric of the outdoor clothing generally takes precedence of waterproof performance, the permeability and moisture permeability of the fabrics used are often not high, which makes people feel rather bored.

There are 9 billion micro holes in 1 square centimeters.

So, can mountaineers and outdoor sports fans wear waterproof, breathable and moisture resistant clothes? Zhu Guangyi, marketing director of Beijing Hua Ze yuan economic and Trade Co., Ltd., told reporters: "over the past 10 years, Hua Zeyuan has been committed to research and development of high-tech fabrics.

Recently, Hua Zeyuan, a subsidiary of Beijing Chiba Bao Lian Technology Co., Ltd., independently developed and developed 3T01-TEX fabrics successfully. It is a high-tech waterproof and breathable membrane designed for professional high-grade outdoor clothing and military police clothing.

Gong Jianhua, chairman of Chiba Bao Lian, told reporters that this waterproof breathable membrane is a kind of E-PTFE film, which has good waterproof, breathable, windproof and warm keeping, blocking bacteria, filtering dust and other functions.

On the 1 square centimeter 3TO1-TEX film, there are 9 billion micro pores, the gap between each micro hole is 0.01 microns, and a drop of water is 20 thousand times larger than these micro pores, and the water can not pass through. Therefore, it has waterproof function, and can resist rain (snow) entry under the strong wind and rain (snow).

The film can withstand 65 pounds per square meter, and when a person kneels on the water, the pressure on the knee is only about 10 pounds, so water can not enter the clothes, so that 100% waterproof.

And each micro hole is 700 times larger than the sweat molecule of the human body, so that the air and sweat can be passed through the cloth in a leisurely manner, so that the body keeps dry at all times, thus achieving the function of air permeability and moisture permeability.

Because of the irregular arrangement of 9 billion micropores in each square centimeter, the film can prevent the invasion of cold wind, and achieves the effect of wind prevention and warmth retention.

Moreover, the fabric with 3TO1-TEX waterproof breathable membrane is very durable, which can prevent contaminants, cosmetics and oil contamination from passing through, so that the product has a longer service life.

Detected by international authorities, its permeability is higher than that of Angola goat skin. Its waterproof and moisture permeable properties have also reached the international advanced level, and the super comfort brought by it is sought after by the world-famous brands in Europe.

The fabric is waterproof, breathable and windproof. Its waterproof and breathable index is much higher than that of the gol company. It is the best waterproof and breathable fabric in the world.

And all the zippers of Chiba Bao Lian suit are all waterproof zippers. The whole set of garments is made of more than 10 YKK zippers, all of which are heat sealed.

Therefore, its clothing can adapt to all kinds of harsh environments such as rain, cold, snow, and so on. At the same time, good air permeability is also suitable for wearing in tropical areas.

At present, Beijing Hua Zeyuan economic and Trade Co., Ltd. has become a professional regional agent of high-end German military police and outdoor off-road brand PFC Professional. The 3T01-TEX waterproof and breathable membrane is widely used in its products. Through the technical cooperation with PFC, it has been allowed to apply all kinds of 3T01-TEX fabrics to all series of PFC products, greatly improving the professional performance data of PFC.

At present, there are several well-known international outdoor brands and Chiba Pauline to discuss cooperation matters.

A few days ago, Chiba Pauline went to Germany to participate in the Friedrichshafen European Outdoor Products Fair. At the same time, the 3T01-TEX fabric was launched and attracted the attention of exhibitors and visitors.
