最近看了有人在我那篇提到如何修复DWR的文章下评论区和我说她们：“登山从没人管这个玩意，根本没有用嘛。俺们认识歪果仁，也从不修复这个。”

我就傻了，我很赞同这个观点。这些公司这么笨，居然这么显而易见的成本节省都看不到。真是醉了。

我马上查了一下。这DWR一个防水冲锋衣最外边的额外涂防水涂层。到底有什么鬼用。

明明太阳可以晒干的唉。

我写的关于修复DWR涂层的文章。

研究后发现，这玩意好像还真有点用。

你看，又有朋友要问了，这都有防水膜了干嘛还要整防水涂层？

我说吧，这你就不懂了。这可是高级货！

我来打个比方

这是一把门锁

这是一把高级门锁

你觉得哪个门锁更能防盗？

当然是四重钢芯，四重加固的超高级门锁啦！

要我说，这就是好冲锋衣的——双重防盗系统。哦不。

防水系统。

“怎么迪卡侬也有这个DWR涂层呢？”

这。。。。。。

（以上为胡说八道。。。）

搞定。

什么？这玩意不透湿。

看看隔壁棉质面料，拉跨。这么多针织棉料都不如咱们的冲锋衣，我宣布，以后所有内衣、毛衣统统用顶级冲锋衣的料子，别问，问就是透气。

然后你快快乐乐的买了一大堆“透气”的冲锋衣。

发现这玩意好像确实完全不如棉的面料透气，咋回事呢？

然后你再去查，你会发现MVTR是Moisture vapor transmission rate的缩写，但这个数据并没有一个标准的实验方法。

那咋办，总不能自己测试吧。。（耳边响起了你行你上的知友呼声。。）

哇，我可买不起这么一大台面料测试的机器。在标准温度湿度下检验面料内外的湿度变化。

我还是去直接搜各家面料厂的测试视频吧。然后。。。。。

除了实验室的B ROLL我啥也没搜到。

我就裂开了。官方没有公布实验环境，但是销售倒是人手一台手捏气阀，可谓是肺活量多大透气性多强。

乃至十年前的某品牌

还有电视节目

以及经典的开水蒸汽玻璃片。。。我傻了

所以

虽说MVTR是面料的透湿数据。

然而MVTR的实验结果受到想到相当多的因素影响。

单说试验标准就完全不一样，压力温度湿度都完全不同。

各家面料厂的实验数据也可能因为标准的问题而与实际数据相差巨大。

Upright Cup test（直立杯湿度转移实验）

Also known as JIS L 1099, JIS Z 0208, ISO 2528, Desiccant Method of ASTM E96, JIS K 6328 (JIS is short for Japanese Industry Standards). The A-1 method uses Calcium Chloride solution to simulate sweat while A-2 method uses just water. A desiccant, calcium chloride, is put into a cup. A piece of fabric is then secured over the cup and placed in a controlled environment. Then after period of time the cup is weighed to see how much water has been “pulled” into the cup through the fabric. The weight is then extrapolated to show the number of grams of sweat passing through a square meter fabric in 24 hours.

Inverted Cup （容器倒置湿度转移实验）

Also known as JIS L 1099 is similar to the ASTM E96-BW test method. A desiccant, Potassium Acetate, is put into a cup and sealed with a piece of ePTFE (Teflon/Gore-Tex film). The fabric to be tested is then placed over the cup with the fabric side to the cup.

The cup is then inverted into a pan of water. Then after period of time the cup is weighed to see how much water has been “pulled” into the cup through the fabric. The weight is then extrapolated to yield the number of grams of fluid passing through a square meter of fabric in 24 hours.

The B-1 variant of test method puts membrane in direct contact with water while B-2 variant adds an ePTFE film between the water and the fabric. While B-2 is a good test, it eliminates the effect of fabric when in direct contact with water. When sweat condenses on the inside of a fabric with a hydrophilic laminate, the lamination will actively pull the water through the fabric reducing condensation. This can be a tremendous addition to the comfort of the user. The B-2 test is also best used for non-waterproof fabrics, so the water in the pan does not pass directly through the uncoated fabric.

Current upper range is 30,000 g m−2 d−1.

Sweating Hot Plate （金属板出汗模拟）

Also known as ISO – 11092 or the Ret or Hohenstein test . In this test, fabric is placed above a porous (sintered) metal plate. The plate is heated and water is channeled into the metal plate, simulating perspiration. The plate is then kept at a constant temperature. As water vapor passes through the plate and the fabric, it causes Evaporative Heat Loss and therefore more energy is needed to keep the plate at a constant temperature. Ret is the measurement of the resistance to evaporative heat loss. The lower the Ret value, the less resistance to moisture transfer and therefore higher breathability.

Hohenstein added a unique aspect to their testing. They had real people wear garments made with the fabrics of varying Ret values and work out on a treadmill. They gathered the comments of the testers and correlated this to the Ret values of the fabrics and came up with a Comfort Rating System.

The testers could not perceive a difference in the garments made with fabrics within these ranges. So, a garment made with a 40 Ret fabric and one made with 55 Ret fabric did not have a perceivable comfort difference in use.

你甚至不知道这个是整体面料的透湿性能还是单塑料膜的透湿性能。

除非厂家提供检验方法。不然其实这也算是个黑箱。

标准的检验方法其实是在International Journal of Clothing Science and Technology 12 (2), 2000.这期杂志有写，请你行你上的杠精亲自去试试。文献链接我放在最后。当然大家要是有详细的测试方法和对比数据可以@我。

新型面料的数据我还没有看，有时间看看。不过多方对比综合性能依旧是GORE-TEX PRO最强。除了价格较贵，其他都还行。

理性消费，不要人云亦云。

（另外目前本人没有恰任何品牌的饭，大家喜欢就点个赞，看看我推荐的商品就好咯，感谢）

凯乐石的三合一gtx算下来算是比较便宜的了，1000出头，双12应该会更便宜。

1000这个价格再往下就是军队公发和一些品牌的库存了。

或者一些品牌的单外壳。

正常户外这些就够了，还是希望大家支持国产。

说老实话迪卡侬也不错。不过迪卡侬不搞返利，价格便宜没有链接，大家可以去迪卡侬的旗舰店选购。

始祖鸟这款多功能高海拔登山服很不错。但我建议海淘。国行翻倍价令人感动。

说来惭愧，我从没买过国行始祖鸟。哈哈╮(╯▽╰)╭（不搞技术攀别买Alpha的壳，重装重心会低一点，设计上也有不少不同）
