A History of the Idea of Glued Linen Armour

[Hanny]

If its of any relevance I just came came across a reference for stiffening Linen in "Wearing the cloak" pg47:

"Nicetas Acominatos in a book written c.Ad 1204-1210 describes the crusader's way of making a linen garment more protective against weapons by treating it with a mixture of Vinegar and salt. This recipe is in agreement with Pliny the Elder who mentions the gauls and parthians used vinegar for stiffening wool."(Plin. NHVIII 192)

And going back further https://books.google.co.uk/books?id=mIaY...bo&f=false  page 277. Here* they use rabit glue https://jhupress.wordpress.com/2013/04/2...our-lives/ and again here with some rudimentary testing of its protection. http://hvitr.blogspot.com/2015/08/linoth...tiles.html

First link* has a book to accompany the research, and why, what for, vinegar was used in the process. http://elbdisliker.at.ua/TermBallInd/ixk1d-bytnt.pdf

Pliny http://penelope.uchicago.edu/holland/pliny8.html
CHAP. XLVIII.
Divers kinds of wooll and clothes.

"Moreover, wool of it selfe driven togither into a felt without spinning or weaving, serveth to make garments with: and if vinegre be used in the working therof, such felts are of good proofe to bere off the edge and point of the sword; yea and more than that, they will checke the force of the fire."
