I dyed some Trispi sails using Rit Dye. I had to simmer them for about an hour. The dye took quite well and I was pleased. I assembled the sails (6 pieces) with 3M double-sided carpet tape. I cut this tape to 1/4 " and use this tape on all my sails. It hasn’t failed me til now. After about a month or so the dyed sails come unstuck. This happens in the sail box. It hasn’t happened while sailing but this is my “B” rig and I don’t use it much. I thought that the dye left some kind of oil or something on the sails so I wiped the joints with laquer thinner and on another occaision with alcohol.When I put the sails away for the winter I made sure they were all slackened off and when I opened the box for this year one of the seams had come apart. This has never happened with the un-dyed sails. Anyone have any ideas?
