We do share some suppliers but I think it's a not a good idea to disclose such things on public forums. 7D soft and 10D ripstop were made custom for us. 7D is a little more difficult to process as it stretches quite a bit.

Glad that you found it! Denatured alcohol is hard to find in a normal supermarket because we don't want to waste alcohol for cleaning/burning They have it in hardware stores like Merkur, Bauhaus, etc... You can occasionaly find it in some small village/farmers markets. A yellow metal bottle with "denaturiran alkohol" text on it is the most common one.

Yeah the photo is a bit off, it is dark olive in reality. I would hide nylon from the sun though

It's about 10g/m (pair) +/- 1g

OT: Thanks, it's indeed 100cm (~40") my abacus is broken at the moment

Yes I tested it, the tape still holds on! At the bottom ob the backpack it started to peel off slightly on some places, but not critical. However, the 50gsm DCF fabric abraded so much it is not waterproof anymore, maybe still has 300-500mm HH. Most notably on rolltop closure. So taping doesn't make any sense on the long run. The photo is from the roll-top area. It would probably be better with fabrics such as x21 with thicker PET film but I prefer good old pack liner. I think taping added about 26g so it is not that light at all.

I am pretty sure It is strong enough for this application. I have my food bag and backpack sealed for the PCT hike this year. I will comment more on durability when I get back. LG, K

I am now testing transfer tape + polycro for backpack sealing. So far results are very promising. Will report back after some months. Big advantage of polycro over DCF is stretch. DCF has almost no stretch, so it is very hard to seal small/micro wrinkles on the backpack. Polycro has a bit worse adhesion to 1163/9485PC tape compared to DCF, but it is still ok. Temperature shrinkage should't be a problem.

Friction is possible explanation but I doubt it is that much of a difference. I think it would be the friction from the needle going back up then. In this case friction is increased mainly because you used thicker needle before rather than needle type. I would say if microtex 80 works fine for you then just use that. Best to turn off the machine when doing that so no accidental pressing on the pedal Not sure if this works with computerized machines.

@Peschamel I'm suprised it works better with the microtex 80 needle. This might also be the cause: Tension discs open up after the presser foot is lifted beyond a certain point. When material is too thick (eg. shoulder straps) tension discs on some household sewing machines tend to open up and loose all upper tension resulting in underside loops like those on your photo. You can check when that happens by pulling the upper thread and slowly lifting the foot. If your machine has adjustable presser foot tension then try to put more tension to it. Method that also works is pressing down on the presser foot with your finger and hand-crank the machine, be careful with that tho
