I'm looking for a solution to get rid of the smell of urine in
underpants like Depends. I would like to use activated charcoal, but I
don't know if it will work when it gets wet or if it's
washable/dryable. I am open to other solutions, but it must be able to
be washed on hot and dried in the dryer and last many, many washings
(or be replacable if only lasting less than 50 wash & dries).
Obviously it cannot stain cloth and it cannot have any chemicals; it
must be completely natural.

Hello Jude1,
It does not seem clear to me, but do mean you wish to put this smell
absorber inside the underpants? And external odor removers would not
do for you?

Yes, built-in, actually, but probably removable. There is already a
charcoal filter for underpants on the market, but it is for
flatulence. http://www.under-tec.com/work.php
I am most concerned about effectiveness when wet (eliminating the
urine smell) and that the solution be able to stand up to many, many
washings and dryings.

Hello Jude1,
I encountered another such product, also for flatulence. Perhaps
activated charcoal will do well for that, but if it gets wet with
excretion, it may not be as effective. Anyway, if I find something,
I'll let you know.

Oops, posted this as a comment instead of a clarification. Here it is again:

I need something that goes on once during the manufacturing process
and can withstand 50+ washings/dryings before being changed. An
after-market spray or product will not work, unfortunately.

Hello Jude1,
Sorry it had been a while. I was able to find an activated charcoal
product that is used in incontinence products, though I could not find
information on reusability or washability. But I believe the product
is reusable. It's from the same manufacturer as a well-advertised
(maybe well-hyped) flatulence odor product.  I'll see what else can be
found.

Here's an interesting suggestion, from a Kimberly-Clark messageboard
for Depends users:

"i have found a new way to deodorize and keep those 'snobby noses' out
of my pants. here it is and please don't laugh because this stuff is
worth its weight in gold, after a call to the manufacturer to be sure
it was safe for us guys and not just the gals i found out that
'summers eve' ultra feminine spray knocks out urine odor for 8 hours
and more. i spray it on my whole diaper area in the morning and i'm
good through the work day."

I have used this product (for a purpose other than urinary
incontinence), and I found it to be very effective:

The following link describes perminent polyester fibers that are
coated with activated charcoal.  Perhaps you could either stitch or
otherwise incorporate a layer of these fibers into your design.
