One Parnell knot undoing itself on the main string

@MAX PLY but wait, how could that be? We have a similar incident later in the thread... After 100K+ (alleged) string jobs using the PK and nary a failure, post #39 had the same thing happen, a scant 4 days after the OP. Coincidence? Divine Intervention? An accidental recreation of the OP's knot (surely not with the history associated)? Or is this a plot by dark and sinister forces seeking to undermine our confidence in the PK knot for some unknown reason or reasons? Is there monetary gain at stake? Or has @Richard Parnell 's namesake simply expired? If it has and he needs to create a new knot, could I name it? Could it please be the Paige Spiranac knot? Please?

It's not 100K+ string jobs. Hundreds of string jobs.
It actually happened twice to me. The first one was when the racquet was still on the stringing machine, and I started stringing a few rows of cross strings... Then one of the main Parnell knots came undone.
It's the string!!!! Too slippery.

@guanzishou sorry I wasn’t referring to you.

My bad...I was in a hurry when reading the post.
I've had a parnell come untied when tying off on teflon tubing (x2). I've since changed my practice,
not the knot. I now make sure i install the tubing basically flush with the end of the grommet when
it's on a tie off grommet (i don't mess with Fitex). Thus (duh) the slippery surface is not an issue any longer.
Is it possible i just mis-tied the knots? ABSOLUTELY.
Also, a dab of superglue can used if uncertain.

They don't make it any more, but Prince Recoil was really slippery like that, and would sometimes pull out of a knot. Probably why they quit making it.

I can confirm that the PC knot is also very strong. I've been hitting with it for a few sessions now

From the pictures I've seen, I don't think Paige Spiranac has any knots. At least I didn't notice them.

Based on the earlier replies, I am pretty sure it is because I did not hold onto the string tail of the knot when I released the clamp. One user has suggested me that after I tie a knot, I should hold onto the string tail, then release the base of the clamp, then release the clamp, and then make sure the knot is tied very tightly.

I think the grommet hole where the Parnell knot got undone was a bit too big (or too flexible/stretchy?), somehow.
I have no problems so far with Wilson Pro Knot.
But I think I like PC Knot the best for this racquet. It seems PC Knot creates enough "bulge" to block that big grommet hole.

I have come to a conclusion that PC Knot is the best for slippery string.
The whole knot is pushing down very hard on the tail end towards the grommet hole, locking the tail end very firmly.

fwiw I've use the double half hitch for decades without any issues on all types of string. I leave strings uncut until I take the frame off the machine.
I have been using Parnell knot on all of my hundreds of stringing jobs with no problem, on my Wilson Pro Staff 90.
I have just started using Toalson Power Swing 400 racquet. I string it with Wilson Synthetic Gut Power 16 gauge, a very slippery string.
The freshly strung racquet hadn't been used, so this morning I took it out of the bag, and voila, one of the Parnell knots of the main string came undone on its own, without being used or played with before.
Why can this happen?
I then strung another Toalson Power Swing 400 racquet, this time using Wilson Pro knots on all of the knots. I had a hit with it for 2 hours no problem. All of the knots stayed intact and the tension feels great and consistent during play.
I've been using Parnell knot and been trusting it for so long, and now with this new racquet I have to change to Wilson Pro Knot... or maybe there are other type of knots that are stronger?
What's the strongest knot out there? PC knot? Double half hitch?
This string I'm using has a very slippery coating!
Pictures:
Parnell knot on main came off on the left side.
Right side: main string Parnell knot on the left, cross string Parnell knot on the right.
Parnell knot for cross string at the top of the racquet.
Edit: I've just strung this troubled racquet using PC knots on all the tie off's. I'll see if it works well. So I have one racquet with Wilson Pro knots, and another one with PC knots.

oil your strings.. is all..haha that would be funny. maybe I should age my reel of PPS if it will make it more slippery!

I find with poly the PC knot locks so early (which is why it's good for slippery strings) that it's hard to get a consistent shape of the knot bulk which determines how it sits in the grommet.
There is a lot of poly on the pro tour, followed by natural gut. My stringing business has similar ratios.
Therefore I rarely need to use it—even Velocity at high tension holds fine with a Parnell for me—but when it's appropriate it's good trick.

These are all just different kinds of stopper knots, ask any skillful sailor.

After I do it The Right Way (quotation), lately I've settled on trimming the first knots down to about 10cm while I finish the rest of the weaving, then when I tie off the last (usually top cross¹) I nip those others down to the final tag end¹.

I’ve used Wilson Synthetic Gut w/ Power almost exclusively on my own racquets for a few years. I don’t know my knots names but I do a PC knot without the last going back through the loop based upon the video in the recent thread.
I HAVE NEVER HAD A KNOT COME UNDONE OR UNTIED. NEVER!!!!
I also like the Head Synthetic Gut w/ PPS, Gamma w/ Wearguard, and Prince w/ Duraflex. Hey. Aren’t these strings all the same??? So if any of you are getting rid of this string, I’ll take it off your hands. I prefer the 17 but 16 will do. The stuff is so cheap and plays great until it breaks in 2-4 hours.

I know this Head is a syn gut multifilament, what does PPS stand for?…never heard PPS before. Is it Head’s namesake like Wearguard is to Gamma, Duraflex is to Prince, etc?

Probably "Polyamide PowerStrip" ?
Synthetic Gut PPS
SYNTHETIC GUT PPS brings the same power, control, and comfort than the MASTER string, but packs some extra speed for club players.

With the Parnell knot, this is usually because you executed it wrong and brought the string through the wrong side of the main when putting it through the half-hitch loop. It will look solid for a minute and then work itself completely loose because you actually undo the first half-hitch when you make this mistake.
