Dyneema thread?

[Darren Graff]

I just picked up some thread at my local fabric shop. I'm not sure if it's dyneema. I googled the company that makes the thread and did not see this thread. The company looks like they make some quality products. Is there a way to test it to see if it's dyneema? Is this a good deal if it is dyneema?

Dyneema?
Some insight on this thread would be great. Don't really have a use for this stuff yet. I would need to get a commercial machine to use T-150. Some heavy duty stuff even if it's not dyneema. I just had to have some.

Looks like most of what Anefil makes is poly/nylon.

Try a "melt test", or not …. see below

Call them.

Edit: Removed bad "melt test" info.

Dyneema is stronger and stiffer than nylon, can you tell just by breaking it and handling it?

[Dave @ Oware]

Dyneema melts at a lower temperature than nylon or polyester. 150 is very thick stuff too. If it is polyester bonded (PB) it should have a breaking strength somewhere around 15 lbs. If it is dyneema somewhere around 70 lbs.

trying to break it in some way would give you an idea.

I did some tests while I while waiting for AMERICAN & EFIRD, INC to call me back. The thread will not take RIT dye. It floats. Picked up a 20 lb weight. Had to use super glue on the knots. It broke at the knot when I tried to pick up 40 lbs. I talked to Dave from the company. Dave said it was indeed dyneema as he remembered. They have nothing in there computer about the thread because it was so long ago and they no longer carry this thread. I asked about the PB being a polyester bonded. He said no he thought it would be polyethylene bonded. I told him about the weight test I did and that it broke at the knot at 40lbs. He said that did not represent the stitch strength because of the knots. He recommended using a T-70 for sewing UHMWPE fabric for backpacks. He was familiar with the speedy sticher and said I could use it in that but most people use nylon for cordura. Looks like I have a life time supply of some thick dyneema thread. Thanks for the comments. God Bless

"If anyone wants some the fabric store has 2 more spools. Just let me know."

price?

spool length?

–B.G.–

[Dave @ Oware]

I'll take a spool.

Trade some 46bonded or 69bonded nylon thread – two 1 lb cones black for 1 lb dyneema. The 46 usually works well in home machines and some home machines will handle the 69 which is equivalent to T70.

or a batch of fabric in something you need for equivalent costs (shipping etc.) . I have cuben, 30dsil, 70sil, momentum 90, 1000d cordura etc.

or cash.

I want to make some knife sheaths and a cut resistant thread would be good.

Dyneema is normally slippery stuff. Don't be surprised if you run into some tension issues with using the stuff. If the line slips through you top tensioner, you will get long loops on the underside that will eventually snag.
