Lou’s birthday! We wandered up to Starfish and Coffee on the far side of Queen’s Park. She made the cushion she sat on. “It’s in good nick that cushion, ” she told me. “Mind you the fabric was top quality. It probably had a 500000 on the Martindale rub count.”
Ok. Great. A new thing to me. To many of us. Today’s blog is coming to you courtesy of mister Martindale.
To test the durability of fabrics you rub in a continuous figure of eight with a certain amount of abrasion and a certain amount of force. How much? Who knows? The internet is not forthcoming on this at all.
Probably around the same time as Mister Kirkaldy was bending girders to breaking point in Southwark, someone in England was diligently circling fabrics with a custom made sandpaper thing and counting. And his name appears to have been Martindale. But even Wikipedia isn’t telling me much about him. AI provides his initials as JG, but AI is often drunk. Also there’s some dilution because there’s a modern electrics company called Martindale founded in Cleveland Ohio 1913.

Right I’ve dug deeper. Seems he wasn’t industrial revolution. 1952 it appears, at the Wool Industries Research Association up in Leeds, a machine was made named after him. Very possibly BY him. He was doing it in the war though it seems. By 1952 he was a doctor. Still not clear what his names were. James George? Testing the cloth at the edges of gas masks (?) was his route into making sure your bum doesn’t go through the seat on the tube. Or soldier wool elsewhere? Socks so they don’t get such wet feet? What was he testing that now he has a test named after him?
“The testing process requires a Martindale machine. The tester pulls the test fabric taut across a series of plates on the lower side of the machine and places discs of worsted wool or wire mesh on the upper plates. The machine rubs the upper plates against the lower plates in a Lissajous curve. The tester inspects the fabric constantly for signs of wear. If there is a visible change in appearance or two yarns break, the test is complete.”
He made it across the pond like The Beatles, but the Americans have their own rival test too. This is just as obscure in genesis and named Wyzenbeek – like they absolutely had to give it the most American sounding name they could muster. He was more direct, mister W. Just a back and forth rub for Wyzenbeek. American directness. None of these goldarned corners.
Friction eventually wears things out. That’s the thing we know. It can be direct and repetitive like Wyzenbeek or it can be curly like Martindale. It’s amazing what people measure. But there we go.
We had a glorious day in the sun today. Up hill and down dale. I’m exhausted.
