 Using Aurifil Spools on Domestic Sewing machines

A handy hint from Pat Sloan to advise your customers about how to place Aurifil spools on their sewing machines:

De-Coding the Spool Label

The information is all displayed on the base of the spool.

Colour code & dyelot numbers are shown:

colour code = 4 digit number eg: 5003 in above photo

dyelot = 3 characters eg: 2MD in above photo

Thread size is designated by the Ne code eg 40 (or 50, 28 or 12)

Plus the spool base itself is colour coded. eg:

Green (above) = Ne 40 Cotton Mako’
Orange = Ne 50 Cotton Mako’
Grey = Ne 28 Cotton Mako’
Red = Ne 12 Cotton Mako’ or Ne 12 Lana
White = Ne 36 Aurilux

Amount of Thread:

GR 30 = the spool holds 30 grams by weight of thread

MT 1000 = the length of thread on the spool (MT 1300, 750 or 325)

Type of Thread:

Mako’ = 100% long staple Egytian Cotton

Lana = 50% Australian Wool & 50% Acrylic

Aurilux = 100% satin finished Polyester

Brillo = 78% polyester/22% Nylon with a metallic wrap

Cotton Mako’ Colour 2000

Color 2000 has always been made up of raw cotton in its natural state, it is a thread that hasn’t been dyed during the manufacturing process but maintains its natural color as if it has just been picked!

Sometimes this will mean that some variations may occur between the “dye lot” production groups, due to how the variations in the weather conditions influence the threads?

As with all the other colours, the dye lot number records a production group and may indicate a change in the final product colour.

A popular application for colour 2000 is for custom dying of thread for specialist uses or for use with designs that will be dyed after production.

What is Aurifil Cotton Mako’?

I sat in one a presentation by another thread manufacturer who claimed that:

“All cotton thread on the market is long staple Egyptian cotton but the special feature of “their brand” is that it is double gassed to remove the fluff and dirt to make the thread very smooth and clean making it better than the others on the market”

After listening to this presentation I asked the Aurifil factory for a response to this claim by an industry competitor:

“If by double gassed they mean a double process inside the singeing machine, this does not make any sense …..I have seen that they write this in their website but really there is NO SENSE in repeating the process after the first pass in the machine ..if you do a second process nothing will change. The thread will be exactly the same as after just one first process.

Maybe a double mercerization could make sense if you have a cheap thread …but with a quality like ours it makes no sense to repeat the mercerization process. However, a double gassed process is really crazy….

Within the Mako’ quality, and within the long staples, there are different qualities according to the area where the cotton is grown. Aurifil chooses it’s thread from two of the top three certified best quality mako’ production areas. It is made with 50 % GIZA 45 + 50 % GIZA 70 …… they are EXTRA long staple cotton.”

I found the response very interesting.

How much thread do you need to quilt a patchwork top?

It is usually possible to complete the quilting on a queen size quilt with less than 1000 metres of thread. Therefore one spool of thread will normally be more than enough to complete a quilt.

However if the quilting is very detailed or dense it is advisable to recommend that your customer purchase a second spool.

How can I stop the Aurilux thread from slipping off the spool?

A spool of Aurilux, satin finishe dpolyester thread.

Like all slippery embroidery threads, Aurilux has a tendency to slip down the spool to “puddle” around the machine spool pin.

The easiest way to stop this happening and tame the flow of the thread off the spool is to lightly wrap, or scrunch, some kitchen plastic wrap around the spool. This slows down the thread as it unwinds from the spool and allows it to feed along the thread path at a steady pace.

As the the spool gets smaller, simply gently tighten the plastic wrap to maintain the tension on the spool.
