保持关键装备干燥 (Part 2)

保持关键装备干燥 (Part 2)

通过 ,2015年5月13日

从我们离开的地方接 part 1 我们的“保持关键装备干燥”系列,经吉姆·伍德(Jim Wood)的许可重新出版,我们’重新挖掘什么使一个伟大的齿轮袋…

齿轮袋标准

使用齿轮袋保持设备干燥可以克服上面讨论的大多数限制。除了保护在路上的重要物品外,它们还可以在营地中提供高度的安全保护。但是,有三个关键因素将决定是否有任何特定的齿轮袋可以完成其分配的任务。

1.面料: The 齿轮袋 fabric must be 防水 enough to provide an adequate level of protection for its contents. As noted above, sleeping bags and insulated clothing are usually the most important survival items to keep dry, but cameras, other electronics, and maps can also require the same level of protection. 效用, first aid, personal and kitchen items, on the other hand, generally need less protection, either because they won’不会因淋湿而受到伤害,或因为它们’re already packaged in their own 防水 “sub-assemblies”. Food that’例如,存放在Ziploc袋中的垃圾就属于此类。

麻袋织物还必须足够耐用以经得起实际使用。例如,将睡袋塞入齿轮袋会在织物上施加相当大的压力–它的侧面和底部都必须足够坚固,以防在此过程中刺破。它’对于麻袋的内侧也很理想’身体的织物要足够滑,以使内容物易于插入和取出。因此,通常应避免使用具有高摩擦内部涂层的织物。织物涂料还应能够随着年龄的增长而保持结构完整性。某些涂料可能会开始防水,但随着时间的流逝,它们可能会变干和/或从表面面料上剥落,从而导致裂缝或其他引起泄漏的损坏。

2.接缝构造: 与织物的强度同样重要的是用于构造和密封麻袋的技术’的接缝。接缝通常是缝制,粘合或超声焊接,但最终至少需要与织物本身一样牢固。缝线通常是“simple”一种类型,其中缝线在接缝或接缝的每一侧连接单层织物“felled” variety, where one or more rows of stitching join multiple overlapping layers of fabric. Simple seams are typically not nearly as strong as 砍伐 seams, but unfortunately, as noted below, are often found in some ultralight “waterproof” sacks.

任何需要在结构上打孔的接缝(带有所有缝制接缝的情况)都必须密封,以防止漏水。胶接缝或超声焊接缝在构造时通常是自密封的。

3.封闭机制: Even if constructed from a durable, 防水 fabric using heavy-duty sealed seams, a gear bag will still leak unless it has a secure closure mechanism. The closure must be flexible enough to work equally well whether the sack is fully loaded or mostly empty. In addition, it should be convenient to use, allowing easy access to gear even when wearing gloves or mittens. And perhaps most importantly, it needs to be able to resist water penetration to the degree required 通过 the value of its contents. Some examples of common closure mechanisms:

无处不在的拉绳闭合 ’在大多数杂物袋中发现的S可以组织“ditty” items, but is pretty much useless for sealing out water when used in its 简单st form.

另一方面,如果麻袋的顶部被扭曲,然后将其折叠并通过将绳索紧紧地绑在双绞线上来固定(如下图所示),则可以使封盖相当防水。由于扭曲和钩子的配置,我将此技术称为“candy cane” closure. It also requires that the ends of the cord be separated, and not joined with a knot, as they usually are when manufactured. In addition, for this method to work, the sack can also be only partially loaded. Further, the knot closure makes it fairly inconvenient to access gear inside the sack, can be difficult to untie if the knot becomes frozen, and if used on slippery fabrics (like silnylon), can often work its way loose with normal trail jostling. For the 糖果手杖 closure, I’ve发现,比绑扎的绳子将粗厚的橡皮筋在钩子上缠几圈更安全,也更容易取下。

像GoLite Paddler储物袋这样的麻袋使用拉绳封口的一种变型。这些麻袋具有可扭转的加长领,然后折叠在齿轮物品的顶部。然后可以将束带收紧在折叠的领圈周围以固定它。但是,仅在麻袋大部分已满时,此机制才有效。如果说袋子是半空的,那么这种闭合本身就没有什么价值。为了防止部分装满的袋子泄漏,在拉紧束带之前,需要将上领子扭绞,翻倍,然后如上所述用另一根绳子绑起来。我认为,这种设计与传统的拉绳封口相比,提供的增量价值很小,而大多数只是增加了麻袋的重量。

卷筒纸可能是干袋密封的最佳方法。固定好后,可折叠成多个袋子’s的织物(通常)压在加劲剂上’缝在袋子的顶部边缘。如果顶部尽可能向下滚动,则袋子’内含物还可以推向织物,以进一步收紧密封,通常会形成有效的阻水层。

卷起后,可以使用位于顶部边缘的单个侧面释放式搭扣,沿着袋子垂直延伸的一或两个皮带(也带有搭扣)或可以与搭扣挂钩的魔术贴环侧翻盖来闩锁顶部沿袋子长度缝制的侧条。我相信,在这三种闩锁机制中,顶部的单个扣(用于大多数桨袋)可能是用途最广的,因为它’无论麻袋是完全装满还是大部分是空的,通常都有效。在低负荷水平下,带有双面皮带的麻袋往往很难密封,有时甚至无法密封。

干麻袋
我没有其他有趣的关闭可能性’t think have ever actually appeared on general-purpose trail sacks, include 防水 zipper seals such as those found on Ziploc storage bags. Even if they were used for this purpose, however, they might be problematic, since they’通常,靠紧密封袋的侧​​面很容易将其打开。现在可以在外壳夹克和背包中看到的那种防水牙型拉链是另一种可能,但我不知道’t know if they’re considered to be truly 防水.
