Have just made 40 hoodies for my daughter's school. MDP hot flex. Pressed for 15 secs at 160 as instructions. Have had 2 people saying that the vinyl had lifted after a wash. I gave instructions to only wash at 40 degrees, inside out and do not iron directly on the vinyl.
Any ideas? This was my first big job and now I feel sick with worry that it has all gone wrong.

When I used to do vinyl I used the MDP hot flex and found the same problem, I remember I tried pressing as per instructions then removed the backing and placed the Teflon sheet over the vinyl and pressed again for 15 secs and never had a problem

Should I just cross my fingers then as all 40 were delivered last week

Is it worth a call to MDP supplies?

Can the hoodies be repressed or would that not help?

You could cross your fingers but then can you trust the 2 have washed them correctly?

it's no harm calling MDP

I've never repressed so I wouldn't like to say yes

I have several items of my own work wear that haven't failed also my daughter's own one seems ok. Will just have to wait and see. It just doesn't give a good impression when I am just starting out.😳

If you have used the exact same material and it has not failed for you (following correct washing and drying instructions) then there is no reason why it should fail this time. In my opinion there are only two reasons why this has happened.

1. You have been supplied a bad batch of vinyl from MDP. They are a reputable company so if they have and you call them I am sure that they would say if you are not the only one to complain and would replace it straight away.

or

2. The two customers have not followed the instructions. Personally I think this is the more likely reason why. Most people ignore the instructions particularly when using a tumble dryer.

You can repress the garments, but what I would suggest is that you get both garments back. Take off the current vinyl using some of that removing spray and then repress using new cut vinyl (same material though). Tell the customer that you are sorry that it has happened and that you have replaced with a higher grade vinyl. I would bet my hat that they will not come back because this time they will follow the instructions :-)

As long as you communicate with the customer and try to rectify the situation (even though you are not in the wrong) then it will be fine. And don't worry too much, it happens to a lot of people (see below)....

That's interesting as I have never heard of that before when it comes to pressing vinyl. I appreciate that if your press is too hot it might not stick, but I always thought that this was an immediate thing and if its stuck straight after pressing then it is stuck for good. You live and you learn ;-)

Excuse the image quality. This is how the vinyl now looks after a wash. Why has it gone all wrinkly? That said the washed it at 30 degrees on a 15 min cycle. The thin line corner on the left is the part that has lifted.

I think that has either been washed at a very high temperature or tumble dried.

If it were me, I would try to recreate the problem. Get a similar material, press something on to it and wash at a high temp and tumble dry. If the same thing happens then it is pretty obvious what has happened.

There are members on here with better knowledge on vinyl (such as Logobear) and would be interested to see if he has seen this problem before and what it was that caused it.

excess heat seems to kill the adhesive, a way to remove vinyl, press at 200c covered with a piece of rough paper, - then rip the whole lot away in 1 fluid motion, - easier than solvents!

Starting to get a sinking feeling :(. Another 2 returns that makes it 5 in total. Something has gone seriously wrong. 1 wash and all wrinkled. I can't afford to redo another 40 hoodies. Let alone the comments that will come my daughters way, children can be cruel.
I have had a look through the forum and it seems a second pressing is what is missing to stop some lifting but as it is not on the MDP instructions I don't think I have a leg to stand on by going back to them.
As for the wrinkling I have no idea if all 5 people have tumble dried or not.

I know I am posting a lot to this thread but I am a very worried man at the moment. I keep thinking of what I may have done wrong. I have had a thought that when I placed the hoodies onto the press I may have stretched the fabric.
When I was pressing the back I was concerned that the pocket seam on the front would hinder a clean flat press so I pulled the back over the lower platen leaving the front below the platen, hope that makes sense.
I have done this with polo shirts and t-shirts with no issues but maybe as the material is a bit thicker on a hoodie that once washed, and they shrink a little bit, it wrinkles the vinyl.

I think your best bet is to create a letter and ask the school to distribute it to all the leavers stating that there is a problem with the vinyl and that you ask for all the hoodies to be returned to either be repressed or replaced (whatever needs to be done).

I think that you are going to lose on this, but I don't think you have a choice.

agree with Social, there was a post here a few weeks ago, every one has problems - its how you deal with them that matters.

get them back, you may be able to repress some of them. did you press the vinyl after peeling ? i must admit i always do. some of the quick wash programmes do not spin very well, then mum or dad leave the stuff in the washer for a few hours, keeping the clothing that wet for that long does not help.

I think stretching them over the platen - unless yours is very small could be an issue here that could lead to the vinyl bunching up

I do not have a lot of experience, but it almost looks like the garments have shrunk slightly. Or the garments have been washed above 40 degrees.
Hope you get this sorted out soon

I still think stretching the hoodies over the platen, then pressing the vinyl on, will have caused this

They have only wrinkled after a wash. Some of them sat in my front room for a week as I was pressing in the evenings after work. If they had stretched wouldn't they have shrunk back whilst lying around? We are washing my daughter's one today. On it's own at 40 degrees to what happens.

id blame 3 things
1. the hoodies ive always had problems with awd never with gildan
2. the wrinkles as mrs m says could be down to streching over the platern certainly looks like it
3. id also say that some of the wrinkles look like they be down to the paper you are using ontop of the hoodies when pressing , is it wrinkled ?

1. Not had issues before but never done this many.
2. Lesson learned on this one. I have just posted a question on the Forum asking where to buy some heat resistant pads to put between the garments.
3. Only greaseproof paper and I change it after about 4-5. They all looked so good when they came hot of the press😭

get yourself down to aldi - they have their heavy duty teflon sheets in now, they are black, and certainly better than using greaseproof paper - why are you wanting to put something in between the garments ??

I love this forum. I wish to say a big thank you for all your advice and help. The rot seems to have stopped and it looks like it has happened to all the Small hoodies. So down to user error. I WILL NOT pull the garment over the platen. I will take Socialgiraffe's advice on another thread and have a look at some training courses.
On the plus side the schools
"Friends" are looking to have a set of coasters as the Christmas gifts for the parents this year and have asked me to give them a price.
