PTFE film manufacturers analyze the application of PTFE film. PTFE film fabric is made of soft and comfortable high-performance surface fabric and PTFE clothing film. It is highly breathable, extraordinary and comfortable, and durable waterproof and windproof. Kill.

★The two-layer fabric feels soft, durable waterproof and windproof;

★The three-layer fabric is a composite of surface fabric, film and mesh lining, suitable for a variety of harsh environments;

★It is suitable for mountaineering, skiing, hiking, fishing and other outdoor activities. Kan

A. water resistance: the water resistance of the fabric is usually expressed by the water pressure it can withstand. the higher the water pressure resistance, the better the water resistance. the water pressure resistance of the ePTFE laminated composite fabric is required to be higher than 6,000mm water column. ePTFE can improve the water resistance of the fabric, so that the wind and snow will not penetrate into the underlying fabric. Kill.

B. moisture permeability: ePTFE nano microporous film diameter is 700 times the diameter of sweat or water vapor molecules, in any case, people wear clothes in the moisture and moisture will be out through the micropores, providing users with a comfortable feeling. Kill.

C. warmth retention: ePTFE layer fabric is windproof because its microporous channel is not a straight channel, and air molecules are difficult to pass through the microporous channel. Even in the case of high wind speed in winter, ePTFE layer fabric can still maintain a warmth retention rate of more than 80%. The advent of super waterproof and moisture permeable PTFE film fabric indicates that Changyongying insulation company has strong technical research and development strength and lasting innovation ability.

Here I would like to try to use more popular language to describe the functional differences between PTFE composite fabrics and coated fabrics and other film materials. There are two key points: the 1 is moisture permeability. PTFE film is microporous, it uses a unique processing technology, so that the film to form a microporous structure, more than 1 billion holes per square centimeter, the opening rate is as high as 80%, the aperture is 700 times larger than the water vapor molecules, sweat can pass through; aperture is about 10000 times smaller than water droplets, liquid water can not pass through. The coating material in the coated fabric, the fabric of other film materials, the general use of PVC, PU and TPU materials are non-porous, and its moisture permeability can only be absorbed from one side of the fabric through the hydrophilicity of these materials, and then passed to the other side of the fabric, and affected by the external temperature and humidity. The higher the moisture permeability, the better the comfort of the clothing; on the contrary, the worse. Therefore, from the perspective of moisture permeability, the performance of PTFE film is significantly better than other materials. The 2 is resistance to harsh weather conditions. The temperature difference of PTFE material ranges from minus 100 ℃ to 300 ℃, maintaining very stable performance,

That is to say, for example, the clothing made of PTFE film fabric has the same moisture permeability at minus 100 ℃ as that at a temperature of about 30 ℃ above zero. However, other PVC, PU or TPU materials have great changes in their moisture permeability with the change of temperature. For example, under the temperature of minus 40 ℃, these materials have been deformed and brittle, and the moisture permeability must be greatly affected. This is why climbers must choose PTFE film fabric clothing when climbing mountains at high altitude, because the core material of PTFE film fabric is PTFE, which is hardly affected by bad weather. Kill.

Talking about outdoor dress, the three-layer principle of outdoor dress is that the inner layer wicks sweat, the middle layer keeps warm, and the outer layer is waterproof and breathable. The principle is nothing more than that the inner layer uses the perspiration layer to bring the sweat from the body to the outer layer, which can also block the entry of external water vapor at the same time, while in the cold, the middle layer keeps warm. What a great.

First, we look at the inner layer, the perspiration layer. We say that outdoor cotton underwear is a big taboo, because it is uncomfortable to stick on the body after absorbing sweat, and it is not easy to volatilize. If it is in a cold environment, it may cause harm to the body, which is true. Then many old donkeys recommend new people to buy COOLMAX, regardless of the environment......

COOLMAX is the 1 kind of sweat-wicking fabric produced by DuPont Company. Its fiber section is 1 kind of hollow cross pipe. After absorbing water, the fabric can quickly pass around to increase the volatile area, so its sweat-conducting performance is quite excellent. In addition, many Korean and Japanese fabrics of the same kind can also achieve these characteristics, but now people only recognize COOLMAX, which is related to its marketing and entry into the country earlier. COOLMAX fabric is more suitable for use in spring and summer. It will be very comfortable when wearing a T-shirt alone. However, if it is also recommended as a sweat-wicking layer in cold environment or in winter, I think it is not comfortable to wear. It will be very cold when wearing the upper body. Moreover, DuPont has another 1 of sweat-wicking and warm-keeping materials called Thermolite, this material has the advantages of light, breathable, warm, soft, can effectively warm sweat breathable, always keep the skin fresh, more suitable for wearing in a cold environment. In addition, Changyong Win Insulated PTFE Film Fabric is also a very good underwear material. Many friends in China are not familiar with it yet. I believe that with the expansion of the market, everyone will gradually learn more about these products. What a great.

Look at the middle layer, the warm layer. The current thermal insulation layer is basically fleece and down products, fleece clothing, we can see a lot in the market, the price also ranges from tens of yuan to more than 2000 yuan, but many friends can not tell how different they are. The simplest comparison method when buying ordinary fleece: look at the thickness of the fleece, see whether the fleece is delicate, and whether it feels soft and comfortable. In addition, there are many new fleece clothing varieties, such as windproof fleece, elastic fleece, ultra-fine fleece, and even waterproof fleece. What a great.

It should be noted that the air permeability of windproof fleece will be worse than that of ordinary fleece, and it will be worse if it is waterproof. There is no way to this problem. Waterproof and breathable are always a contradiction. Ultra-fine fleece is now more applied to some inner wear clothing, pay attention to comfort. Finally, talk about the outer clothing, that is, windproof, waterproof and breathable assault clothing. Now it seems that people talk about the most, ask the most, we are always asking. Some old donkeys just use their own feelings to tell others that the * * * charge clothes are good and good, but they can't tell what's good about them, and there is no horizontal comparison with other products. I don't think it makes much sense to talk about them. What a great.

Generally speaking, mountaineering clothes will choose three-layer adhesive fabric. Although it is hard and not so comfortable to wear, it has better abrasion resistance and is more suitable for mountaineering. The trekking section is mostly made of relatively soft two-layer fabrics, which are more widely used. Travel models focus on lightweight and portability of clothing, represented by long-win insulated PTFE film fabrics. Casual models are more focused on style, such as Colombian clothing. What a great.

I hope the above description will be helpful to you, and we look forward to cooperating with you!
