I'm sure this has been discussed plently before but I'd like to know how you auto guys are removing lint from garments. I feel we spend waaaayyy to much time stopping the press and picking lint off screen and patching up shirts. Today I ran 5 jobs with white on darks and I had to have stopped at least 20x. Especially when doing waterbase base or straight natural discharge you have to wait till it gets to the back of the dryer to find out you got lint in the screen. We ran 4,000pcs earlier this year that should have been a slam dunk quick run, D-White on orange and navy shirts, felt like we were stopping every 12-24pcs to pick out lint. We do have a roller squeegee/frame from Action and sometimes we apply some spray-tac to the bottom side but it don't last long and we tried their velcro stick on and thought it didn't work great either......... Please share how you guys are "delinting" your shirts.
MUCH APPRECIATED!!!!!!

The war on lint has never been won..
-
I've recently been wondering how everybody copes with lint getting into the ink on screen and into open containers? A problem at the moment while I'm doing black hoodies and white ink and I can see the lint settling in the ink - just not sure how much it affects the printing...
-
Lint is the only product we actually manufacture if you agree with the defination of manufacturing as converting one raw material into another. Every thing else we do is a value added service that we get compensated for. ;D
-
One way I used to do the lint removal was to use an air hose and have someone blow the shirts before they reach the printing head. Also a quick snap of the shirt before loading helps.

I wonder if you could rig up an air knife on head 1?
that being said... we've successfully used a regular screen with a light mist of spray tack on it in head one before... super light squeegee stroke (like around 10-15 psi), so the screen is literally JUST coming into contact with the shirt... it would last at least 1000 shirts before we'd need to apply more tack
-
I saw someone was using their ROQ flock vacuum attachment to suck up lint balls on the first head. I forget now where I saw that.
It's not really helpful in this case since you're running a Sabre.

This is what we used to do at my last shop (I'm currently auto-less), but we also put a healthy smear of shape in the screen to give the squeegee something to push around & reduce friction. The tack had to be refreshed every once in awhile. Not a total fix, but it was better than nothing. Add an extra snap of the shirt while loading, and it greatly reduced problems on linty/stringy runs.
(FYI, we used the same approach minus the tack, with heavier pressure, to smooth down certain fabrics. Don't remember the situation, but there's a bonus tip if anyone ever needs it.)

Aren't lint screens pretty much a must unless you need the head due to max color counts? I was planning on rigging my jav up to run one on head one, base on two, flashback on 3, etc. Rarely print 5 colors at the moment.

I'm going to bet this depends on who you ask. We only used a lint screen occasionally, when a batch of shirts had enough lint/strings to keep slowing us down. (In case it's a factor, our jobs were typically in the dozens to hundreds, not thousands like some of the contributors here.) I couldn't argue whether that shop's ways were best, either; that's just the way we did it, and it seemed fine for the work we did.

Get you an operation like this and you should be fine.
(Make sure you make it to at least the 2 min mark :) )

Makes sense. I print lots of comfort colors though so lint is a nightmare and I will be doing anything possible to mitigate issues it might cause once I get the auto setup. I can't imagine it would be more efficient to keep picking at shirts like I have to now...

What the hell is that horrible screeching noise. And why do they have like a double loader?
-
I am a shop owner that is never really only about the pure speed at which we print a run of shirts. I will concede the speed of a run to make it look better. ie; Double stroke, extra flash, revolve, etc...
With that said...This video is killing me!
That would be a one person run for my shop...not 3. (4 if including the person with the camera)
That looks like a lot of wasted man hours. I could find something for the employee that is handing shirts to the loader to do that would be more productive. Like catching the shirts that are piled up at the exit of the dryer.

I bet it was first run on new press everybody wanted to help, probably got over that quick

Here's our solution - works great!
Each Kit Includes
2 Teflon coated screens
1 16" Roller Squeegee
How Does it Work?
Spray a light coating of adhesive (not included) on your two Teflon coated screens. Place onto Head #1. Use a Roller Squeegee to get the best contact with the garment. Any and all loose threads and lint balls will be picked up by the screen. When it gets dirty, your second screen is ready to use and minimizes downtime. The laminated Teflon film on the screen makes it very quick and easy to clean and reuse. Eliminates the lint in screen problem.
$525 per kit.

This is what we are doing now, we tried the velcro sticky that we purchased from you guys but that did not work very well or maybe we did not do it right? This has been the best solutions so far but not a fix of this problem....as someone said earlier maybe the lint war can never be won!!!!

I see lots of battles won in here..
the war rages on

I guessing they ordered the optional Green Screech-o-Lator. But I hear they are discontinued, so you can't have one.

On our newer presses that have heads that raise and lower, I have my lowest off contact just kissing the pallets. I simply put pallet paper on the print side of a screen, spray a little mist adhesive on the pallet paer. I set the head to zero off contact so it just touched the shirt. This grabs the lint. I can't do this on all of me presses, and of course you have to have the capacity.
-
We do it with the squeegee and spray on the bottom. Does the job and don't have to buy anything.
-
We use a lint screen (we call it a hickey picker :) ) with an action roller in head #1 but we don't use spray tac, we us WB adhesive rolled on. It is much more effective than spray tac.
We use pallet tape on the back of the screen... you don't need Teflon on the lint screen.
-
Sounds like a war that will always be fought!!!!!
-
Coated exposed screen, some soft base ink and regular floodbar and squeegee, we put pallet mask on the bottom of the screen for easy clean-up, mist adhesive whenever you re-glue the platens and it takes care of like 98% of the lint problem on the backs of subsequent screens.

this pallet tape idea on the back of the screen sounds like a great idea. gonna have to try it on our next lint screen... will certainly make for easier cleanup...

I left this part out when I described our process. Makes cleanup easy. And yes, we used a coated screen for the shape to push around in.

We use the ROQ ASP Flock vac to suck up all the lint on large runs..... We recently did a 17,000 pcs order and did not stop one time for lint. The roq vac has enough power to suck all the lint/strings up but not mess with the tack. Really good option for all the roq shops but it will only work on roqs.

did the same thing 20 years ago doing flock..
I stuck a shop vac attached to a copper pipe with a slit cut into it and fastened it to a cut down flood bar.. with a simple adjustment of zip ties and mouthfulls of bad words..
We won that battle!
