In reply to Simon Wells:
> Any way I think the Captains points was more to do how 'wetting agents' help, not sure about that at all!
No, that wasn't my main point. I originally only discussed the effect of detergents/wetting agents on the wicking ability of the pile because you said that wetting agents would
stop it wicking:
"never use normal washing powder as the wetting agents stop it wicking"
My point was that wetting agents will not stop the pile wicking;
if anything, they will improve the wicking. A wetting agent, as its name suggests, is intended to allow water to soak into a fabric better, to assist cleaning. 'Wicking' is another way of saying 'soaking into'. Whether you want to, or need to improve the wicking is a moot point. By default, the polyester pile will wick.
Using a wash-in DWR treatment
will stop the pile from wicking (making it work like a reversed Paramo 'pump liner', where capillary depression would drive the water out of the pile, and towards the body), which is why I suggested a spray-on treatment for the Pertex shell only.
Washing in detergent
will negate the effect of the DWR treatment on the shell as it is supplied by Buffalo;
that's the reason that Buffalo suggest (as I would) washing in soap; to retain the protection provided by the DWR, not because it will adversely affect the wicking of the pile.
> Apologies if my use of the word authoritative went over your Captains hat
> So 'authority' as in 'he really knows what he is talking about
It didn't go over my hat at all; I'm quite prepared to accept that Hamish understands how Pertex and pile/Pertex works better than I do, but you haven't actually said what Hamish thinks about it, or provided any links to such an explanation.
I won't accept any authority's statement without actually knowing what that statement is supposed to be, or understanding and accepting the rationale behind it. Manufacturers' explanations are often a lot of waffly pseudo-science BS (Accapi, for instance) that defies scientific understanding.
> ...but decreases its ability to move sweat / inseasable perspirataion.
If I'm sweating so much that it would wet out the face Pertex, I'd want to try to reduce my sweating by other means; it would mean that I'd be saturating the pile with sweat, which would be bad from the perspectives of overheating, dehydration and chilling when static. Mild sensible perspiration, and insensible perspiration should be dealt with by evaporation by body heat within the pile, and release to the environment via the breathable Pertex shell.
> Excellent summary of my point
Thanks. Up to now, I had no idea what your point was, because
you hadn't actually made it...
> Please Captain I need a reply to keep this thread as a top posting to advertise the Buffalo Bundle!!
The main reason that I've continued to respond is that I don't like to see unresolved misunderstandings, either on my part, or on someone else's part. So I've tried to present my side of the argument. I've also presented what I think is your side of the argument, for balance.
I'm glad to hear that it's had the secondary effect of helping you shift your pile-pertex items...
