Need blueprint for a PET cotton maker

Precious Plastic Machine Development
#1

Hello,
I need blueprint for a plastic cotton maker. The plastic used is PET plastic, which is easily found in Indonesia, in the form of used beverage packaging bottles. It is planned that this cotton will be diverted to spun yarn craftsmen, then converted to cloth. That way, PET plastic can turn into other fabric-based crafts.

Examples of machines can be seen in this video:

The shape of the machine in the blueprint can be different, provided it has the same function. Maybe someone in this community can help me.

 

Thank you

Thanks for posting, I didn’t know about these interesting machines….Sorry, I can’t help with the design.

great; thanks Donald. the last video suggests it’s cheap; at least for an equipped machine shop. Eventually you can reach out the maker of the video to get the details as Stan suggested. Nonetheless, I would do some extra research on how this stuff is any good for us. A quick search unveils it’s rather not; as often low-tech recycling degrades material to lower applications.

@mrking Have you tried contacting the Youtube poster of the video to see where the machine came from? It looks like a compact effective machine. Why try to design something new?

@mrking; I had some more thought on this and searching the net told me it’s a pretty complex story. It’s hard to make prediction on this machine(s). I remember from my visits in older textile factories that even those old machines are very sensitive to the yarn you feed them with. It requires an engineer in the field to set this up right. However, it seems that the process is first the creation kind of PET filament and then pull it as seen in the videos (link) through various processes. I’d say for 10000 and 2-3 months labor you could probably build a prove of concept machine but it won’t hold up long nor produce much. So if you could please give some context, budget, location, workforce, etc… eventually I can narrow the options down for you.

Based on the manual from PreciousPlastic.com, PET has begun to be produced into yarn. In Indonesia, there are still many yarn craftsmen and fabric craftsmen whose main ingredients are cotton, which is usually planted by the community, in several regions.

But now, the need for cotton has begun to increase, while cotton farmers have decreased. Therefore I need help to make this tool.

 

Can the method of cotton sugar machine be applied to make synthetic cotton made from PET plastic? Has anyone tried it?

yeah; the downside is that PET at that size is easy to destroy; our oceans are mainly filled up with PET …

I think i’ve got an idea how to make it. You could extrude the PET flakes, through a die, then cool it down to a perfect temp to slice it up with ultra sharp knifes like on a lathe; it seems to happen extreme fast. I think the next steps are far more complicated; for this you need a little genius to build a suited machine.

Hmm….
I’m just trying to realize all these ideas in my city. PP has opened the idea that waste management can be carried out directly by the wider community in their homes. In our city, the opportunity to process waste is also controlled by large companies, but that is not enough to reduce the amount of plastic waste.
With the idea of ​​this machine, I hope to open people’s minds, that garbage can also be converted into a high marketable product. During this time I did it only with a simple tool, not using a Shredder or Extrude machine, not yet. The items that can be made are still limited.
But if in the end I found a way to make a machine, I would try to share it with this community.

yup, no more footages or links. that’s an idea. But if anyone can design the machine, I will make it real here.

 

obviously it uses heat elements and air blower / compressor. but I still doubt how heat (in celsius) is needed to melt PET, so that it can be blown into cotton.

You have more footage, links etc…?
Getting so little flakes is already a challenge 😉

Its oke 😉

I hope other members will realize and care more about the idea of making synthetic cotton, as an opportunity to treat plastic waste. Hopefully there are people who are kind enough to design this machine.
