Here are some additional pointers to consider when you are making a curtain using a velvet. Remember that a velvet is just a type of fabric and the fibre(s) that the velvet is made from is important.

So for example we would always recommend that you line a curtain. This gives a superior appearance but also reduced the amount of light going through the fabric hence limiting as much as possible the effect of any fading.

If the velvet has a pile that can be flattened in one direction then we would recommend that you have the pile going downwards for SHINY velvet fabrics and PATTERNED VELVETS.

If however you make up the curtain with the pile upwards then this will deepen the colour so you cold make the curtains this way for cotton velvets and Trevira Velvet and Mohair velvets.

These are general guidelines and it is not necessarily wrong if you make up the curtain ‘the other way’ just so long as you understand the implications to the finished look and performance of the material.

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.

Hopefully that made sense. Good luck.

Mohair Velvet

Mohair Velvet – A velvet made from natural Mohair Wool. Typically durable with high Martindale rub test results. Natural fibres give a degree of inherent fire retardancy.

Cotton velvet – A velvet made from natural cotton

Linen Velvet – a velvet made from natural linen typically an excellent domestic upholstery velvet.

Silk Velvet – Potentially beautiful and amazing velvet fabric made from silk but a high degree of quality variation across manufacturers.

CS Trevira – Made from synthetic Trevira. Excellent contract velvet.

Cashmere Silk Velvet – Extremely high quality luxury fabric. Mix of two natural fibres ie Cashmere Wool and Silk. Combines beauty with durability.

Vicuna Silk Velvet – Extremely high quality and rare luxury fabric. Rarely available as an interiors fabric.

Cotton & Silk Velvet – A less expensive way to strengthen the beauty of the silk with the strength of cotton. Cotton being cheaper than Cashmere wool for example!

Note also that a velvet is made with a back cloth material. It is not unusual for an extremely fine top market velvet to have a 100% cotton back cloth.

“Black Diamond” is the colourway name for the Italian Silk Velvet (100% Silk Pile) with the code 777-108-900.

You can get black silk velvet samples here from KOTHEA if you are a trade professional. Just click the link.

KOTHEA velvets are the best in the market. We only sell top market fabrics, mostly to top European Interior Designers and Architects. Here are some more bits of technical information on our black Italian Silk velvet fabric:

Width: 140cm

Composition: 100% Silk Pile

No repeat, plain.

Abrasion: Martindale 20,000.

Available from stock, normal delivery within 5 days.

Minimum Order length: 2m

Anyway, just a heads-up. Check where your silk velvet is being manufactured and double check the quality.

Perhaps the most expensive yarn is from the vicuña (vicuna, vicugna), which is a camel-like animal found in the high alpine areas of the South American Andes. Whilst not an endangered species it is a rare animal and difficult to farm as it tends to escape!

Cashmere yarn comes from the cashmere goat and other goats such as the pashmina goat.

Cashmere and Vicuna have an outer layer of hair which is coarse and rough but protective for the animal. This is the guard hair. Underneath the guard hair is a warm layer of much, much softer hair. This underlayer consists of hollow-fibred hair that is an excellent insulator. The vicuna has the finest of these fibres of any (resultant) wool anywhere in the world.

About 400g of yarn can be produced from one Vicuna compared to 150g from the Cashmere goat, the latter being a smaller animal. There are many more Cashmere goats in the world and I suspect this is why Cashmere is relatively affordable – as it is produced in much larger volumes in a more competitive market.

As an indication a Vicuna scarf would cost in excess of US$1000. As far as I know it is not produced in sufficient quantities to be available in a suitable form for interiors use (I could be wrong). But if it were it could be woven with silk to produce THE MOST EXPENSIVE AND BEST woolen silk velvet in the world. A further problem is that the Vicuna fibre can readily be damaged when dyed, again making significant production quantities problematic.

Now, as much of the Cashmere yarn produced comes from China, Australia and other countries…in fact just about anywhere other than Kasmir! it strikes me that is an opporutnity waiting to happen for some illustrious, economically-minded, goat breeder out there with friends in the textiles industry. If the production problems could be overcome I could see that there still would be a market for an interiors fabric retailing at in excess of GBP800/m  (US£1300/yard) – albeit a small one.

Interior Designers are often interested in the properties and manufacture of velvet – the two being necessarily related. The depth of the pile, the durability of the finish, the ease of maintaining the beautiful finish.

Velvet is made in one of two ways – cut or uncut:

1. Cut pile

a. Here the loom is configured to have two fabric cloths being woven on face-to-face, one on the other. The pile is woven from one into the other. The cloths would be bound together were it not for a moving knife that travels between the two.

b. Wire loom

Here the yarn is looped over a wire above a single cloth. A knife cuts the top of the loop as the wire is withdrawn.

2. Uncut pile

Very similar to the wire loom except the yarn is NOT cut as the wire is withdrawn. This method gives the fabric even more depth and interest.

Dyeing & Finishing

Velvet is often woven in ‘greige’ in longish lengths of 200m or more. A further stage is added whereby individual pieces are cut and coloured to precise colour formulae. KOTHEA use this way to be quickly able to turn around orders for bespoke colours from stock of the greige. Precise chemical dye mixes ensure good replication of colours for re-stocking.

After colouration the fabric is finished. This involves tumbling and brushing and a backing applied.

Different types of pile effects: If the yarns are finished upright then the effect is called, funnily enough, upright pile. Alternatively a panne pile is one which is flattened so that the pile is laid in one direction.

Often you will hear of Mohair Velvet. Mohair is just one of the kinds of yarns that could be used. It could equally be linen or cotton or a cashmere and silk mix.

Velvet Fabric Includes Mohair Velvet

Velvet Fabrics by KOTHEA include Mohair Velvet, Cotton Velvet, Linen Velvet & silk velvet. The most popular being mohair velvet the most luxurious being Cashmere Silk Velvet.

Essentially you need to look at the Martindale or Rub Test result for the specific fabric in question. Two silk velvets can be quite different.

As with all velvets a proper cleaning regime is important to extend the life of the fabric.

One of KOTHEA’s silk velvets has a rub test/Martindale of 25,000. This is more than adequate for general upholstery.

Yes. We do. Ours has a 100% linen pile and a Martindale of 20,000 making it suitable for upholstery and curtains.

We sell other velvets including; mohair velvet; silk velvet; cashmere silk velvet; cotton velvet and linen velvet.

Mohair velvet can be notoriously difficult to clean. If you are in any doubt please contact a professional cleaner. You will probably get that recommendation from most fabric companies. The following information is provided as a guide and is not a formal recommendation by KOTHEA.

As with many fabrics, prevention is the best cure. A regularly cleaned velvet will last longer and cleaning should consist of brushing with a hard clothes’ brush and regular vacuuming. As part of a cleaning routine we would suggest expert cleaning approximately every 5 years.

Removing Stains

You should never attempt to remove more serious stains. That should always be undertaken by a professional.

It is possible to remove minor stains but always test any cleaning method on a small area that is not normally visible.

For stains that have not dried try using an absorbant and dampened, lint-free cloth. Do not use a coloured material as the colour may rub off into the velvet. Should water fail to work you could instead try a diluted upholstery shampoo/cleaner carefully following the manufacturer’s instructions. Rub very gently on the fabric, finishing in the direction of the nap. Afterwards ensure that all chemical residues are removed.

Make sure the fabric is not used again until thoroughly dry.

Dealing with wear and tear

As indicated earlier, a regular cleaning regime is requried for velvets. If no such regime is followed the fabric can become prematurely worn most noticeably, for example, on the regularly used parts of sofas or chairs. Frequent movement by a person on the velvet pile will cause the pile to be pushed in all directions; sometimes, eventually, resulting in matting. Once the pile has been moved in different directions the shade of the fabric can appear to have changed. This is a natural property of the fabric and is exacerbated by excesses of heat or humidity.

Fortunately, mohair velvets usually take and keep colour well and usually also have high rub tests.

Only on clean fabric try the following; apply a thoroughly clean and dampened cloth for 10 hours and then dry naturally for 10 hours in a well ventilated room. Only dampen the cloth slightly with pure/distilled water. Never ‘wet’ or soak the cloth or the fabric when cleaning.

Velvet is a type of tufted fabric woven with a warp pile. It has a short dense pile of 3mm or less (‘plush’ has a pile longer than 3mm) and a distinctive feel. During production wires lift the yarn creating small loops which are either cut or left depending on the desired finish. Velvets tend to take colour very well and also tend to be hard-wearing with a high degree of suitability for varied uses; they were typically hard to clean but that problem is mostly solved with modern dry-cleaning.

What’s in a velvet?

Kashmir was probably the birth-place of velvet in the early 1300s but by the 16th Century Bruges had become the leading source of what at the time was a definitive luxury item. Luxury velvets are still made in Europe as well as in Asia.

The original velvets were typically silk velvet. With the passing of time and increasing technical sophistication it has become easily possible to make velvets from many natural and synthetic yarns. At KOTHEA we have velvets at the top end of the quality range made from fine yarns including Linen Velvet, Cashmere-Silk Velvet, Linen Velvet, Cotton Velvet, Wool Velvet and of course Mohair Velvet. Other velvets available in the market have compositions that include polyester, nylon, viscose, acetate or mixtures. Sometimes small amounts of lycra are included to give the fabric stretch.

We have many velvets of differing compositions (Silk Velvets, Cotton Velvets, Linen Velvets, etc.) and we were interested to see how one of the velvets, at the very highest end of our range, would perform. So we used SGS to test one of our Cashmere Silk Velvets (75% Cashmere 25% Silk).

The tests were undertaken in accordance with BSEN14455 (based on BSENISO12947) and a result of 13,000 rubs was obtained, which considering the perceived delicacy of the product was fantastic. 13,000 rubs makes the product suitable for light usage such as residential.

Essentially the fabric’s life is increased with better durability and resilience. The handling characteristics of the fabric can be improved; and knit backing also helps prevent seam slippage.

The same principle applies for the fabric whether or not it is to be used for either upholstery or wall covering. There will certainly be other requirements for contract usage, say, in hotels and aviation and also other treatments like fire retardancy or stain protection would be required for contract upholstery.
