pchapman 261 #1 September 27, 2012 Sometimes one sees a reserve that has some color staining, from dyes bleeding, or also discoloration from brass grommets against the reserve fabric. What opinions are there on that? I don't know of any specific problems with it, but the topic came up among a couple other rigger friends of mine. (Sure, any bad stain on a reserve is worth a tensile test.) Is there any reason to expect any fabric issues from staining in contact with brass grommets? I'm not quite sure of the chemical process involved. Sometimes there's the greenish colour of a particular copper oxide, but I've also seen reddish stains. Discoloration does crop up from time to time. I wonder if it happens to rigs in a very humid environment, not necessarily from getting the rig wet without a repack right away.

councilman24 36 #3 September 29, 2012 I work on many canopies with red bleed. Never were wet. Some Ravens and some rounds ALL seem to have bleed from red thread. Never has been an issue. I don't see much on canopies from grommets but have never found an issue.I'm old for my age. Terry Urban D-8631 FAA DPRE Quote Share this post Link to post Share on other sites
