Do a search on invisible thread on this forum - you will find lots of advice.
I found that laying the thread in a jar behind my machine helped to prevent it springing off the spool and tangling around the spool holder. Also loosening the top tension is necessary otherwise the thread seems to drag and stretch and breaks before you realise what is happening.
I used it in the top only with 100% cotton in the bobbin.
Good luck - Once you sort out what suits your machine you should be fine.
