Nylon 6 or polycaprolactam is a polymer developed by Paul Schlack at IG Farben to reproduce the properties of nylon 6,6 without violating the patent on its production. It is a semicrystalline polyamide. Unlike most other nylons, nylon 6 is not a condensation polymer, but instead is formed by ring-opening polymerization; this makes it a special case in the comparison between condensation and addition polymers. Its competition with nylon 6,6 and the example it set have also shaped the economics of the synthetic fiber industry. It is sold under numerous trade names including Perlon (Germany), Nylatron, Capron, Ultramid, Akulon, Kapron (former Soviet Union and satellite states), and Durethan.
Nylon 6 is synthesized by ring-opening polymerization of caprolactam. Caprolactam has 6 carbons, hence 'Nylon 6'. When caprolactam is heated at about 533 K in an inert atmosphere of nitrogen for about 4-5 hours, the ring breaks and undergoes polymerization. Then the molten mass is passed through spinnerets to form fibres of Nylon 6.
This was a job we did on the mill because we didn't have the right stock at hand to do it on the lathe. We use a SCT 3 flute uncoated carbide mill.

Tomorrow's coming 'round
A hair-pin curve in the road
She's got a run in her stocking
And she's missing the heel of her shoe
Got up this morning rolled out of bed
I spilled a diet coke
Called my mother said, "Hi"
What I meant to say was, "Why is your life a joke?"
Then, I went down to that ugly bar and
I clicked my heels three times just like you said
And I climbed that road to your empty house
The anticipation was a turn on
But you let me down
'Coz, I stood on that empty street alone
I said, "I'm ready for my close up now, Mr. Demille"
I waited for the light, but it never shone
Well I wonder what you do with that expensive piece of land
That overlooks a billion years of history
I have a sneaking suspicion, you will never understand
Hey maybe I'll see you down by the Rocky and Bullwinkle
And we can talk to that charlatan psychic
And she can paint a prettier picture of your future
'Coz that day in my life, that day in my life
I dreamt tomorrow, had a prettier face
I dreamt tomorrow, would have better things to say
Than, "You look like shit, what's your problem, bitch?
You're legs feel like sandpaper, you can't do anything right"
'Coz that day, never should have taken place
'Coz this day, in my life still cannot explain
Why I listened in the first place to you?
Oh yeah, something else
I hope one day you call up your father
And you have the guts to tell him, how he hurt you
And he made you hurt another
