EVENT Fabric For Outdoor Sports Escort

EVENT Fabric Excellent breathability is achieved through a continuous change in the structure of the polymer, rather than adding a thin layer of PU on the eVENT/TransActive. Up to now, all films must be coated with a layer of PU to protect them from human body fat / grease or detergent. But the flaw of PU is that it absorbs moisture and keeps it moist. It is precisely because eVENT/TransActive does not have this layer of PU that its membrane pores remain open to ensure that water is unimpeded.

EVENT/TransActive's direct air permeability and direct active moisture transfer function are attributed to two aspects:

1. moisture and moisture are not directly discharged through film absorption.

2. due to the fact that temperature difference is no longer a necessary condition for its function realization, air flow is transmitted at high performance at any time without any time interval. This effective moisture and moisture treatment can be prevented. clothes The inner layer is sweaty and effectively protects the body's body temperature from too low.

TransActive (active moisture conducting) membrane system is constructed from sandwich structure. The outer surface of the "climate surface" is the water repellent layer, while the inner layer is the water absorbing layer, which draws the sweat from human body to the outer layer. The middle is a thin film synthesized by water absorbing and water repellent elements, which performs the function of drainage system. Once the sweat of human body is condensed into the inside of the fabric, the system will operate immediately, the greater the temperature difference between the inner and outer layers, the higher the operation efficiency of the system.

Another advantage is that TransActive has a higher air permeability of 40% than that of the pass film.

According to the Kansas State University KANSAS STATE UNVERSITY test, the permeability of eVENT/TransActive is 2 times that of GORE XCR.

The difference between eVent, Gore-Tex, DENTIK and other fabrics

　　 EVent fabric Like GTX and DENTIK, they all belong to PTFE membrane products. They are waterproof and breathable, but they are different in later stages. The post processing is mainly oil proof treatment, GTX adopts PU coating, eVent adopts direct treatment and no PU coating. Since PU can block some pores of PTFE, the permeability of eVent is higher than that of GTX. I have seen two companies at the same time comparing fabrics, and the permeability of eVent fabrics is higher than that of GTX. But this high is relative, that is, due to the influence of environmental humidity, breathability of all kinds of breathable fabrics under different humidity is different. It is said that at 70% humidity, eVent is higher than 30% of GTX air permeability. Under 30% humidity, eVent is higher than GTX2 times, that is to say, on a sunny afternoon, the clothes that wear eVent are much better than GTX, but in rainy weather, two kinds of fabrics feel almost the same.

According to the few players who use event equipment in China, the event stuff is reflected. Pizex , shoes Indeed, it has better air permeability than similar products of popular GTX.

Where does eVent come from?

EVent was developed by a company called BHA in the United States. BHA is a wholly owned subsidiary of GE (General Electric). It is also listed on Nasdaq, and its share price has always been good. BHA is the largest filter supplier in the United States. Its main business is industrial filter. In Shanghai, there is a joint venture that has been in operation for 10 years. The outdoor fabric is BHA's intervention in 2001, and its products are officially launched in 2003. Its market is mainly in Europe, and now there are about 30-40 European and American brands. Its outdoor products account for a small proportion of the company's operation, and its share in the US military procurement has risen to 40% higher than that of GTX in the past year (about the proportion of its purchases in military procurement). In addition, BHA, Canada, Taiwan / Singapore / Germany / Italy's military, fire alarm and so on, accounted for a large proportion.

Because BHA/GE is a company with pure technical background, its marketing is rather poor. Compared with the business background of GTX25, EVENT still has a long way to go. According to relevant sources, eVent has adjusted the global market strategy since 2006. It is said that there will be some big moves, but it will focus on the promotion in the European and American markets. Since the outdoor market in China is still in the ascendant, its promotion in the Chinese market may lag behind.
