Dearest Teabagologists,
As a sheepy I of course luff tea....my current fave is Redbush....it's well nice !..has a vanilla-ish thing happenning in it !
Look, here's a Redbush Tea Bag having just performed it's duty in my mug !

A Redbush Tea Bag after it's solo act
Nice eh ?....I'll get more when I do shopping next Tuesday.
Tea Bags are a curious thing aren't they ?.....
How are they sealed ?
What is the material used ?
How does it remain strong enough to not deteriorate when wet ?
ewe see, I just do not know, but as I drink my Redbush I would like to know. I will drink it slowly so that by the time I finish my tea I have the answer. After which, ewe are all invited to tea.
Hugs et les shmishes
mwah mwah mwah

I find that if I reuse a bag for a second cuo that theu then begin to deteriorate!
Oh, I would love a cup of tea,,,Thanks!
hummmmmmm!
I often wonder if it is the same material they use for some interfacing? i don't know though.. Maybe Pelon!
-
This is tea but not teabag related.... but I'll post it while I think of it. I love this site! [;D]

Yes, yes,,I often can get up to 28 cups from one bag of tea ! [;D]

"Nonwoven fabric and tea bag
United States Patent 7498281"
"A nonwoven fabric characterized in that the nonwoven fabric is a thermoplastic synthetic fiber nonwoven fabric having a fabric weight of 7 to 50 g/m2, an average yarn diameter of 7 to 40 µm, a partial heat contact bonding ratio of 5 to 30% and a content of a delustering agent of 0.5% by weight or less, or a nonwoven fabric laminate the major component of which is the thermoplastic synthetic fiber nonwoven fabric, and that the nonwoven fabric has a maximum opening diameter of 200 to 2,000 µm, and shows a transparency of 50% or more, a powder leakage ratio of 10% by weight or less and a hydrophilicity of less than 10 sec, and a tea bag in which the nonwoven fabric is used."
From:http://www.freepatentsonline.com/7498281.html
I was thinking its because of its woven fibers.. a weave or woven material really adds strength to the fabric ..so by using a woven material seems like a way to strengthen the bags...but apparently not!

Wonderful information..THANK EWE Kareny mam...I had it in my head that they were not 100% synthetic and that there may be at least be some natural material therein

Oh....sorry Neil.... started to comment in your post instead of hitting the quote... had to take my post out....Lol..
anyway doesn't it seem odd that a non woven be stronger then a woven...or is that just me...
Well thinking on it it would be closer to a solid that way except for liquid loss...so I guess that makes some sense!

No worries Kareny Mam..I have corrected the faux pas by correcting my post....see ?..see how kind and considerate I am ?
I agree....woven should be stronger..than non woven.......now I want to know why ?

I tried redbush once but the cheeky cow dumped me the following day!
-
Here, if the bag is made from a thermoplastic synthetic fibre then should I be putting my used teabags in the composter?

Best to get a dumb blonde and dye it !! [:)]

Our council say it's Ok to put teabags in the food waste recycling green bin thing they gave us !...which is nice !

I would have thought woven but if not I am not sure why not.. woven would seem to be kind of locked together?
Thanks for setting the post straight again.. and yes it was very kind of you Kind Sir! Thank you so much!

From memory and a date with Frances ( which shows you how exciting company she was that i remember this) we walked along the south bank of the thames and found the "tea museum" which had examples of tea bags from the first through to now. It was a bit of a rip off for what was on show and very superficial.
( sounds a bit like her too :-) sorry a bit harsh, without alcohol she had an ingrowing personality.)
It only described the heat sealable process in any depth as sponsored by...
I remember the earliest tea bags I encountered in the 60`s as a tiny child were stitched or with a string and staple sealing it.
The heat seal papers are bleached ( why?) versions of the same fibres used to make coffee filters with a small percentage of thermoplastic fibres that are food inert such as polypropylene (tupperware?).
the heat bonding of these locks the fibres together.
non woven technigues have been used for filters of all sorts and disposable "cloths" for years, about 1970 something called tygan ( I think? plse correct me if i remember incorrectly) was introduced, last seen on the white covers of old 8" and 5 1/4" floppy disks, a heat sealed fibre mix, you could see the fibres and it was very tough and hard wearing.
(NOTE be very careful when googling "teabags" or "teabagging machine". as Google is based on the lowest common denominator who don`t drink tea search, you may get 18+ results.)
I can`t find any definite spec for the fibre percentages to confirm if the suppliers definition of "low" percentage of polymer fibre matches mine.
