Following on from the discussion about using overlocker cones on a regular machine which turned into discusson about Moon thread.
Moon is made by Coats but it's not found on their main website
https://www.coats.com/en/ under products -> threads
But I did find
https://www.antrimm.co.uk/Moon-id10364.aspxand from the full product specification sheet.pdf I get the info that it's a staple spun polyester thread and comes in four sizes:
Ticket 30 = 80 Tex
Ticket 50 = 60 Tex
Ticket 75 = 40 Tex
Ticket 120 = 27 Tex.
A lot of retailers just say "Moon" with no indication of the size, but those who do give a size say 120, which is the finest in the Moon range.
Going back to the Coats website
https://www.coats.com/en/Products?type=Threads&type=Threads and selecting staple spun polyester from the substrate tab the only products are Astra, which comes in
seventeen different thicknesses, also Astra FH (which is anti-wicking for tampon removal) and Astra Rugged for sewing denim.
So I suspect that Moon is actually Astra in a special put-up for the domestic market.
Güterman SewAll is the domestic put-up of Gütermann Mara 100.
https://industry.guetermann.com/en/product-finder/mara-100 https://consumer.guetermann.com/en/product-finder/sew-all-threadMara is also a staple spun polyester thread and comes in a dozen different sizes from 8 - 220 all with a choice of regular, silicone free or water repellant.
Size 100 is Tex 30
https://industry.guetermann.com/en/product-finder/mara-100The commonly available Moon size 120 is Tex 27.
Gütermann SewAll is Tex 30
With my tension on thread windings, Moon measures 30 wraps per cm and Gütermann Sew All measures as 31 wraps per cm the Moon thread is marginally thicker, but a visual inspection definitely shows it to be fluffier.
Overall conclusion:
1000 m of Moon should weigh 27 gms
1000M of SewAll should weigh 30 gms
The Moon is less firmly spun and therefore incorporates more air to make it appear thicker. That will be the reason why it is fluffier than Sew All.
The higher twist, and more fibre per metre, of Sew All should also make it slightly stronger than Moon.
Disclaimer - there are lots of other good threads are out there too, but also a lot of not so good threads too.
