Cotton is made up of multiple fibres that is taken and spun together into strands to make thread. The best quality fibres are the longest fibres as these will create a significantly less linty thread. You can see this for yourself by taking longer strands of hair and twisting them, then doing the same with shorter strands of hair.

Another way to measure thread thickness is by tex. This is a more technical way to measure thread as opposed to weight. It is defined by how many grams 1000m of that yarn weighs.

The longer hair has fewer ends poking out than the shorter strands of hair. This is what the term “long staple cotton” is referring to.

Because gassing a thread adds cost to the manufacturing process, some companies choose instead to cover the thread with glue or residue to keep the cotton fibres lying flat and give the illusion that its low on lint. However this residue will still come off in the sewing machine and can often be even more difficult to clean out than lint. Knowing whether a thread has been gassed or not is a great reference to its quality.

WonderFil manufactures all of its cotton thread only from long staple cotton, one of the highest calibres of cotton fibre quality. This cotton can only be grown in moist, mild climates, a few of which can be found in the southern United States or the delta region of Egypt. Even in Egypt there is variation in climates. For instance, Giza cotton is an extra long staple Egyptian cotton grown in close proximity to the Nile river, a veritable oasis in the otherwise dry climate. Because of the Nile’s mineral rich water and the region’s warm, humid climate, it makes the perfect environment for the highest quality cotton to be grown. For example, Efina™ thread is manufactured from this extra long fibre to create a clean, ultra low lint thread that looks and feels gorgeous.

Multiple threads are used wherever quick motion is required and application of great force is not allowed e.g. on fountain pens, bottles, tooth-paste caps, valves, etc. to impart quick action in opening and closing.

For instance, a 100 weight thread will be super fine, while an 3 weight thread will be closer in thickness to yarn. While this term is used almost ubiquitously by sewing companies, there isn’t really a definitive system to measure it. Most manufacturers know how thick a 40 weight thread looks like and will use that as a reference point to base other thread weights on. However, since there is no definitive system to measure thread weight, you might find some minor variation between thread weights from different thread companies.

High speed steel can be sharpened to a finer edge than carbide, but will lose that edge quickly in hard or abrasive materials.

If you want to achieve perfect edges for steel girders, you can use an angle grinder or a beveler.

Mercerization is a standard process used on cotton yarn. You’ll notice that almost all cotton sewing thread is mercerized, but what exactly does that mean?

However as a result of this process, it also slightly increases the strength of the cotton and gives the yarn a silkier, more lustrous appearance. Natural raw cotton material is dull looking, however a mercerized cotton has a soft gloss to it.

Cotton yarn is mercerized by soaking hanks of it in a caustic soda that is pulled and stretched repeatedly between rods. This process loosens the fibres to help it absorb dye in the next stage of manufacturing.

However if you have a denser thread, or the thread is made from a heavier material such as steel wool, you might end up with a higher tex despite the strands not being a smaller diameter than a cotton thread with the same tex. This is why we use weight to measure most of our thread lines, with some exceptions.

The thread passes between two flames, removing about 80% of the lint from its surface. WonderFil actually repeats this process a second time, so the remaining 20% of the lint has another 80% removed. This double gassing in combination with the long staple Egyptian cotton its spun from results in an extremely low lint cotton thread.

So for example, if 1000m of a certain thread weighs 20 grams then it’s tex 20. Or if 1000m of the thread weighs 30 grams, then it’s tex 30. With tex, the higher the number, it usually results in a thicker thread. Whereas with weight, it’s defined by the higher the number, the thinner the thread.
