Most of us are familiar with the wool that our parents or grand-parents knitted with. Let’s use that wool as a generic example.
That wool is a YARN. It is a spun thread.
It is made of individual fibres that have been spun together to make the yarn. Fibres are threads or filaments or perhaps even animal hair.
The yarn can be woven into weaves/patterns. Usually a weave has many long thread running running as a warp through a roll of fabric. That weave typically also has another yarn running at ninety degrees from left-to-right called the weft.
Fairly simple. On the whole.
Knitting is not really weaving. Lots of kinds of weaves are used in knitting but knitting includes other methods as well as weaving. I’ll stop there !
We are sometimes casually reminded that “you pay for what you get”. Buying cheaper goods obviously encounters a lower cost on day 1 but as time passes the costs of cheaper products can raise their ugly head. Surely fabric is fabric and immune from this?
Sorry, no. Fabrics vary tremendously in quality and Faux Leather is no exception. Faux leathers are synthetic and can be manufactured following several processes. Good faux leather will be influenced by:
excellent quality raw materials,
ensuring the precise drying time for the paste to bond together the ‘layers’
Using the correct temperature.
Shoddily or speedily trying to manage these factors necessarily leads to a bad product. The product might look the same as another but the truth will out as the fabric starts to be used in earnest.
Differing kinds of upholstery Faux Leather will then be subject to treatments to make them suitable to the intended end use. So, for example, some have chemical stabilizers to reduce ‘fading’. If an insufficient concentration and purity of stabilizer is used then UV performance will degrade.
The quantity of material used in each layer too plays a very significant factor in cost and quality as the industry reference, Coated Textiles: Principles and Applications, notes;
Upholstery-grade cloth has a thick foam layer ranging from 360 to 480 grams per meter squared, a top layer of 180 to 360 grams per meter squared.
Cheaper faux leathers fail to meet these tolerances.
Faux leather needs the correct certification for the intended end-use. Otherwise the fabric can be flammable. A major UK retail furniture vendor was recently blasted for using cheaper, incorrectly treated faux leather upholstery fabric.
The cost of rectifying this poor quality is significant. Transport and re-upholstery costs are huge. Is it worth the risk to you as a designer or specifier?
With Faux Leather Upholstery Fabric, you really do pay for what you get.
Up-and-coming Fabric Designer, Zoë Etter, was recently commissioned by KOTHEA to update our linen ‘Alpha Boucle’ upholstery fabric for S/S 2017 to incorporate new elements for the luxury market. The muted fabric features the addition of embellished and tufted yarn in simple linear shapes which are designed for a smart, contemporary look for the home.
The refined designs are aimed at clients who want a simple, durable style that is visually effective. The soft colourways combined with the rich textures offers flexibility for a statement upholstery that is classic in style with a modern edge. Most suitable for chairs and soft furnishings, the fabrics’ 3D look is inviting, and remains comfortable whilst giving a luxurious feel.
Abstract shapes, bold lines and textures typify most of Zoë’s design work, whether it be for fashion or interiors. Photography strongly influences the start of a project and is always at the heart of her work. It is predominantly inspired by natural forms which are interpreted through mark making to create bold patterns and textures. Her most recent collection is based around neon florals for the festival-goer.
Another recent project focuses on strong monochromatic designs inspired by the Cornish coastline, which are ideal for creating a graphic look for warmth and interest in a room.
Zoë can be contacted for private commissions directly on email@example.com or through zoeetter.tumblr.com
Some farbics beautifully arranged from our Spring 2015 Collection. A vey nice (we think) staged image in a set full of light diffused from some white souble-wodth sheers. 3 differing and contrasting cushions arranged off-centre on white contempoary seating
When your sofa is full up the obvious place to put your spare cushions is in that bath tub in the corner of your lounge. We have several new Spring 2015 collections waiting to hit the sewing machines of London.
Ever wondered what a Martindale rub test looks like?
We’ve already shown a video of this <here> however of some additional interest might be the following faux leather samples that recently came back to us from the Martindale testing laboratory.
So the link (above) shows you the machine in action and the image above shows you the circular cuttings taken of the fabric that have been rubbed, in this case, 200,000 times. As you can see this excellent performance faux leather of ours lasted WELL above the industry ‘norm’ of 100,000.

A woven warp-pile fabric where the loops are formed by applying a high tension to the ground warp and a very low tension to the pile warp. Beating-up does not occur on every pick, so that when a pick is beaten-up it causes the other picks to be moved into the main body of the cloth, at the same time forming the pile loops on the face and back of the cloth. Thrown Silk
Yarn twisted from continuous filament silk.
Cut pile weft or warp knitted fabric. Velvet

I would be rich if I were to be given one pound for every time we are asked, “What is the best upholstery fabric to use on my sofa?” Typically the questioner means ‘most durable’ rather than ‘best’. You could buy a near bullet-proof fabric with a Martindale score of several hundred thousand but could you live with it!
‘Simple’ measures of durability such as Martindale and Wyzenbeek overlay complex structures of the fabric. This covers the construction of the yarns and design of the weave weave as well as the fibre chosen. Furthermore, finishes, sofa/furniture design, maintenance regimes and usage are variables that very significantly affect the life of your fabric.
There is a close link between fiber strength and yarn strength. Yarns are twisted to add strength – generally a tighter twist gives a stronger yarn. This is measured in Twists Per Inch or Meter (TPI or TPM). Tightly twisted yarns are generally smooth and dense. This brings us to weave design. Weaves can be extremely complicated and difficult to structurally model and understand. Just knowing the fibers, yarn and weave construction still doesn’t answer the basic question – an objective measurement is needed. Test were developed to determine wear. They are better known as abrasion tests and many Interior Designers today refer to these test results as THE way to measure fabric durability. Abrasion test are supposed to forecast how well a fabric will wear in upholstery applications.
There are two tests: Martindale in Europe and Wyzenbeek in the USA. The tests are different and there is no correlation between the two. With Wyzenbeek (ASTM D4157-02): a piece of cotton duck fabric or wire mesh is rubbed in a straight back and forth motion on a piece of fabric until “noticeable wear” or thread break is evident. One back and forth motion is called a “double rub” (dbl rub). Whereas with Martindale (ASTM D4966-98): the abradant in this test is worsted wool or wire screen, the fabric specimen is a circle or round shape and the rubbing is undertaken in a figure 8, unlike the straight line of the Wyzenbeek. One figure 8 is a cycle – hence the terms Martindale cycles.
Contract fabrics would normally meet these criteria:
General contract: Wyzenbeek 15,000 Martindale 20,000
Heavy duty contract Wyzenbeek 30,000 Martindale 40,000
Medium use residential Wyzenbeek 9,000 Martindale 15,000
Heavy use residential 15,000 Martindale 30,000 or higher
The higher the result the more likely the fabric is to be more durable. (Source of the above figures can be provided on request to the author)
With figures over 100,000 then there may be an issue with the applicability of the results and certainly how the fabrics’ care regime is implemented will have more of an influence on its longevity.
Some commentators question the validity of test results. In my experience in the UK, test houses are independent and are strictly monitored by British Standards and no one fabric company is big enough to be able to ‘ask for’ results to be skewed. Nor, I’m sure, would any fabric company want to put a supplier in that position if only for the reason that it is in no-one’s interests to undermine the authority of independent industry bodies that, in general, regulate for the greater good of all.
You’ve just ordered a new velvet and unrolled it to admire your purchase. But how do you re-roll it?
When you roll almost any fabric you should have the face on the inside. With a velvet this is the pile so you have the pile on the inside.
Some, but not all, velvet piles stand straight up others will ‘lay down’. for the former it does not matter which way you then roll the fabric (provided the pile is on the inside). However for typically longer pile which lays down (ie you can brush it flat with your hand in one direction only) then you should roll the fabric down the pile as you return it to its roll.
