Sewing Machine Thread Brand and Type

[IRO]

They have two products. And one of them is for sewing maschines, but only 3 colors and two thicknesses. I am a seller of Ritza threads in Germany

[Wizcrafts]

The only Ritza thread suitable for sewing machines is Ritza 44. It is only available in black, white and one shade of brown (JK21). It is not waxed, but is lubricated with a silicon coating. It currently only comes in 0.6 and 0.8 mm widths and is a flat braided polyester thread. Some sellers in the World may have new old stock of the 0.4mm width, which is now discontinued.

Ritza 25 Tiger thread is waxed for hand sewing. The wax will strip off as the thread goes through the eye of a standard sewing machine needle, clogging it up. If any of you are thinking about running Ritza 25 through a sewing machine, only do this on a hook and awl machine; not a closed eye needle machine. Examples of suitable machines include the Union Lockstitch, Campbell-Randall Lockstitch, Randall Lockstitch, Landis 3, Landis 16, Landis 12 series, the American Straight Needle sole stitcher, all Puritan chainstitch machines and most hook and awl sole stitchers, including most McKay insole stitchers.

People on our forums have tried running Ritza 44 and 45 on their 441 clones and had numerous problems. One problem is that the spools are not designed to feed off the top like normal industrial spools do. The Ritza spool will fight all the way if you put it on a standard thread stand and try feeding its thread up to the loop above the spool. For consistent results, you should mount the spool so that it feeds directly inline with the spool. This can be by mounting it on a post on top of the machine, where it may struggle to rotate freely, or by constructing a horizontal mount behind the machine to let the thread spin the spool on the shaft with less resistance.

Possible workarounds to use waxed thread in a closed eye machine.

1. Use an oversize needle 2 sizes larger than you would normally use with that size of thread. You want to have as large an eye opening as possible in the hope that the wax will simply pull through it with the thread. However, the wax will still get stripped by the top guides and tensioner, as well as the check spring.
2. Run the thread through liquid silicon or clear sewing machine oil in a lube pot on top of the machine. Do this before any thread guides if possible.

And 0,8mm is also in JK26 available.

So:

Ritza 44 0,6mm silicon JK1, JK21, JK23

Ritza 44 0,8mm silicon JK1, JK21, JK23 and JK26

Thank you Wizcrafts for your explanation !!
