看了,除了价格黑人外,穿挂的方式都不适合极端天气。我去专利局查下有没有申请专利。谢谢楼上的。 <br />
好的品牌都有好“黑”的价位,这个没办法,读史使人明鉴,专利方面你自己斟酌吧...
自从双向拉伸PTFE问世以来,早就吸引了无数帐篷设计者和商家的眼球,特别是上个世纪八十年代出品的各类PTFE帐篷并不少见,并有一些设计精品出现,特别是以Bibler为代表的典型,但销售方面并不尽如人意。请参看说明当时状况的这段文字:
Until 1986, W.L. Gore made a Gore-Tex tent fabric that several manufacturers used in a variety of tents. Unfortunately, those tents could not pass the rather arbitrary fire-retardancy tests that conventional tents could, and so could not be sold in a handful of states. Eventually, Gore took the fabric off the market. Most tent manufacturers abandoned any attempt to make tents of waterproof/breathable material, but not Bibler, who found a way to produce his own version of Gore's tent fabric. Bibler tents are well-made and very lightweight but quite expensive.
防火测试方面的难题、较重的重量和不可避免的凝露使得当时PTFE单层帐篷热潮迅速降温,一路英豪大都知难而退,尽管若干年后Event的出台又因为其高度的透气性能和相对稳定的表现又刺激了一回单层帐篷情结拥有者的神经,从而又掀起了一股设计制作PTFE单层帐篷的热潮,然而,即使是财力雄厚的GE老大,也不能不面对他们所面临的防火测试方面的死结而不得不限制其旗下的Event应用于帐篷领域,而Event客户除少数外则另觅他途:
General Electric purchased eVENT and now restricts its use in tents due to flammability considerations. Integral Designs and other manufacturers no longer use eVENT in their tents. The Nemo Equipment Tenshi tent is among a rare few tents that are still constructed of eVENT.
不过文中的这个Nemo Tenshi(有人叫天使),这个貌似为单层帐篷的终结者确实不一般,虽然不敢说自己的帐篷没有凝露,但是在设计上则大量应用了改善帐篷通风的结构和措施,虽然也是应用Event,但重量方面则比以前的产品更有优势。Bibler方面则我行我素,痴心不改,不论最终的老板是谁,最终毕竟搞出来一个Todd-tex,令人刮目相看,也被称为是唯一通过美方阻燃测试的PTFE面料。虽然有相对更好的透气性,但面料重量方面则不占优,而且也始终是无法摆脱低温下结霜方面的困扰。
下面转帖几张用PTFE面料制作的几款帐篷图片,韩国方面的设计很一般,图就不上了: |
