NOT ALL MERINO IS SUPERFINE MERINO

Merino sheep produce Superfine Merino fleece - but not all of them.

There are lots of strains of Merino sheep to be found around the world - Australia, the US, China, Germany, etc.,  but it is the New Zealand merino strain that produces the finest fleece.  The fleece of other strains of Merino simply does not meet the same standards, and it is only the finest of Merino fleece that can be made into garments that can be worn next to the skin.  And this is where the customer can be easily confused.

Just because something is labelled as “Merino” don’t assume it will be smooth and fine enough to wear next to your skin. Merino fibres ranging from 18-21µ are considered the best for all-round performance, durability and comfort. However there is much on the market that definitely falls below this standard.

Companies across the world are cashing in on Superfine Merino's hard earned reputation by labelling garments as “merino”when they are in fact a mix of merino and synthetic. They trademark names like “ActiveWool” “Powerwool”, and “Prowool” - great names - except these "wools" are 75% synthetic, 30% synthetic and 44% synthetic respectively.  Whilst this is not illegal, we think it's certainly misleading.

Some companies are even labelling their Merino as "Ultra Fine" when it is actually 21 micron "Fine" Merino. This is illegal and one company has already been told by Trading Standards to relabel.   What is also illegal is labelling something as "100% merino" when it isn't.  This is exactly what the New Zealand Wool Testing Authority found when they tested merino fabric made in China.  They discovered that it was in fact merino mixed with viscose.

The fact is that genuine superfine merino is rarer than cashmere.  There is no way that a cheap "merino" garment can be genuinely superfine merino.  There are several ways in which "merino" garments can be made more cheaply:

• Using parts of the fleece that are less good quality.  The best part of the fleece is the back and shoulders. Other parts are coarser, with less crimp and tensile strength.
• Not sorting the fleece to a high enough standard and leaving in the short fibres that cause pilling and itching.
• Using "slipe" wool - or "dead wool".  This is wool chemically recovered from carcasses and is of inferior quality.
• Using ordinary, non-merino wool, and chemically treating it to make it feel ostensibly like merino. It will not however perform like Superfine or Fine Merino.
• Chemically stretching wool fibre to reduce the micron count. This results in a weak fibre only suitable for felting.
•  Treating ordinary wool or coarser merino wool fibre with acid to remove the outer scales.  Whilst this will reduce both the micron count and the itch factor, it also removes the wool's anti-microbial and other properties.

As only tests of  micron count under a microscope would reveal the truth about any of the above and this is too expensive a procedure to carry out on all the "merino" coming out of China companies think  they can get away with this.  We, however, have run samples of merino fabric under the electron microscope, as well as under a standard microscope and the results can be  seen here.

What the experts in t he wool industry in New Zealand  are saying is that they do not believe there is enough quality superfine and fine merino available to meet China's needs.

What can the customer do to ensure they are getting the real thing?  Being wary of buying "merino" at a low price is a good starter, because one thing is for sure, and that is genuine superfine merino is in short supply and is not "cheap".  If you buy a cheap product it will NOT be the genuine article.

How to check for quality when buying merino

One simple check is easily done with the naked eye - the check for  "cockle".  This is a particular problem with lightweight (under 180 gsm) single jersey fabrics.  Lines or ridges appear running laterally across the fabric. This is due to a distortion of the fabric as a result of the inclusion of thicker than normal  range of fibre diameters in the yarn blend, or the yarn setting, and/or loose knit density and overloaded wet finishing machines.  Cockling is  therefore a sign of poor manufacturing standards.  It is a signifier for pilling, and therefore itching when worn.

Another easy way to check quality is to hold a garment up to the light so that you can see a single layer of fabric.  if you see areas of fabric where it is thinner in some places than others, this is another sign of weakness.   

More evidence of poor quality is uneveness in the knit. The more even the knit, the smoother and more stable the fabric.  It is hard to achieve this with a single jersey fabric as this is prone to “spiralling”.

Putting a price on quality

We think we sell the best merino in the world.  Our gear is made from genuine New Zealand superfine and fine merino wool fabric made in New Zealand by the world's leading company, Designer Textiles. What we do not sell is &#34cheap&#34 merino. Whilst the word “cheap” can mean inexpensive, it also means “poor quality”, “second-rate”, “substandard” and “inferior”.  We do not sell “cheap” merino.

What's in a name?

If the term “Superfine” or “Fine” isn't used to describe the quality of merino in a garment, you can bet that it's because the merino being used does not meet the criteria for Superfine or Fine quality. The result is that you could easily end up buying something that will itch, pill, and shrink in the wash.

We have seen some of this clothing. To put it bluntly it is poor.  It feels itchy, looks poorly cut and sewn, and is rarely machine-washable.  In fact we would say that if that cheap merino T-shirt or top you've seen isn't machine washable - avoid it like the plague.  It's a very good sign that the quality is poor.  Another sign is washing instructions telling you to wash it with a harsh fabric like denim to remove the "fluff".  You get what you pay for.  

Micron counts

Merino comes in several grades, from "ultrafine" to "strong" dependent on the micron count of the fibre.  Merino wool is generally less than 24µ  in diameter. Strong (broad) wool is 24-25µ, Medium wool is 22-23µ, Fine 19-21.9µ, Superfine is 17-18.9µ, and Ultrafine is under 16.9µ.  Attempts are being made in Australia to produce fleeces even finer than this, but for the most part, these can only be produced by housing the sheep in sheds.  Not exactly free-range!

Ultra fine wool is still the rarest grade commercially available and can fetch prices of over NZ$300 per fleece. When a single fleece only makes 5 garments, do you really think that Chinese-made baselayer you've bought claiming to be made from "ultrafine" merino is the genuine article?  We don't think so.  Ultrafine merino, apart from the cost, is only really suitable for babywear, fashion garments, or blending with other fibers such as silk and cashmere.

The micron count of a merino fabric is based on an average of micron counts found per square metre, and this is where we find most of the quality short-cuts being taken.  For a genuine superfine merino fabric, the microbn counts should fall in a narrow range, with few if any of fibres coarser than fine being found, and few of the thin, weak fibres below 16µ.

Our tests of a number of merino fabrics found on the UK market show a very wide range indeed of micron counts ranging from as low as 14 to as high as 32!  This sort of range of micron count will not produce a high quality yarn or in turn, a high quality fabric.  See here for our SEM results

However, even micron count alone is not enough to ensure an itch-free, non-pilling garment.  The wool fibre also has to have the right staple (length), tensile strength, and crimp (that's the curl).  Unless all four of these are present, the fibre will not be good enough.  Even then, if the wool fibre is not sorted so that the short ends are removed, the resulting yarn will be poor as will any fabric made from it. So do not be mislead by claims of low micron count.

Ethical Manufacture

There is also the issue of where and how that “cheap” - or even expensive - merino T-shirt is made. Most merino clothing, including Icebreaker, is made in China. Here, environmental issues are ignored, as are human rights.  Wages are kept deliberately low. Some of us feel this is unethical on a variety of counts. Even worse in our opinion is to manufacture in China but still try to give the impression in advertising that it is made in clean, green New Zealand.  

Some companies even go to the lengths of importing it back from China into New Zealand and selling it from there into the UK and Europe.  We don't think this is very good for the environment - carbon footprints etc., but we also think it gives the misleading impression that Icebreaker is still New Zealand-made, when it isn't. Could this be on purpose? There are also companies who hide where their clothing is made by having it made in China, but finished in another country so that it carries that country's "origin" label. This can even be a European country.  We think this is downright dishonest even though, surprisingly enough, it's legal.

Animal Welfare

Animal welfare issues also contribute to the price of your merino.  The practice of mulesing is not practiced on the New Zealand merino sheep that provide the wool for our clothing.  However mulesing is still carried out on Australian merino sheep, and for all we know it is practiced on the merino sheep bred in China, much of whose wool finds its way into Chinese-made merino clothing.
