Researchers are hard at work developing textiles with optimal functionality : tights that apply moisturizers, garments that absorb odours and regulate perspiration, fabrics capable of protecting themselves from spots. Tomorrow's clothing will be intelligent and functional. Cosmetotextiles have already reached the market. A video report illustrating the research being carried out to develop intelligent textiles is available to television stations, at no cost and royalty-free. It was filmed in specialised research centres: in Belgium, near Liege, the Centexbel laboratory is studying electronic applications for the textiles of the future and the reaction of fibres to nanoparticles. The French Textile and Clothing Institute (IFTH) is working on controls of new materials to test their resistance to fire, water and tearing. The report includes interviews with: Christine Hubner, Schoeller Textiles Martine Degueldre, Centexbel Jean Léonard, Centexbel Yvette Rogister, Centexbel Jacques Maguin, IFTH Christophe Angelloz, IFTH
It's the fashion show season, and in parallel, Paris has been hosting the largest textile
00:00:00
show in the world, Premiere Vision.
00:00:06
Seven hundred and forty-two exhibitors from 30 countries presented their offerings for
00:00:10
the autumn-winter 2007-2008 season.
00:00:15
And this year, some special guests, so-called intelligent fabrics, textiles, for example,
00:00:20
that have built-in protection against staining.
00:00:25
If you imagine normal cloth being flat, with nanotechnologies, the cloth takes a form a
00:00:29
little like mountains.
00:00:35
The structure is invisible, of course, and dirt can't stick to a material like that.
00:00:37
It runs off.
00:00:42
So here, I'll put a bit of ketchup on, and I'll take some water, and there, you see,
00:00:45
it's a white cloth, and you can rinse off the dirt immediately.
00:00:51
Stain-resistant materials, bacteria-resistant materials, mosquito-resistant materials, materials
00:00:57
that can absorb smell or reduce perspiration, materials that can measure your heartbeat
00:01:02
or your breathing pattern.
00:01:08
Textiles that are totally impermeable, textiles that are ultra-absorbent, cosmetic textiles
00:01:11
that moisten the skin or apply perfume.
00:01:16
The world of intelligent textiles is expanding, and a multitude of European research centers
00:01:19
are part of it.
00:01:24
Here at Sintexpel in Belgium, not far from Liege, scientists are dreaming up the next
00:01:26
generation of intelligent or functional textiles.
00:01:31
Prototype maker Martine Delgerda's job is to transform these dreams into reality.
00:01:35
Here we have a pullover that's entirely knitted.
00:01:44
The keyboard is supple.
00:01:47
It enables the user to send a range of different commands.
00:01:49
The keyboard was conceived for handicapped people, to allow them, for example, with a
00:01:53
given code, to open a garage door, to switch on the television.
00:01:58
We've also got undergarments that allow you to monitor different body functions, breathing,
00:02:04
heartbeat, and so on, using electrodes that are in direct contact with the body.
00:02:10
We can also insert fiber optics into carpet.
00:02:18
They're integrated in the production process and to make the carpets luminous.
00:02:22
They can be used for emergency exits, for example, if there's a power cut, or just to
00:02:31
create pretty patterns within the carpet.
00:02:36
We've also used fiber optics in knitting.
00:02:41
This creates the possibility of luminous knitwear.
00:02:44
It can be used for outdoor safety clothing, or it can be stuck on walls and ceilings for
00:02:48
decorative effects.
00:02:53
The most complex of these prototypes is probably the textile keyboard, which can also function
00:03:04
as a simple calculator.
00:03:10
Jean Lennart has spent two years working on it.
00:03:12
The key, the interaction of materials that do and don't conduct electricity.
00:03:15
In addition to the conventional materials, which are electrical insulators, we've used
00:03:22
metallic fibers that do conduct electricity.
00:03:28
The principle is that when you don't apply pressure, there's no contact between two conducting
00:03:32
layers.
00:03:37
And when you apply pressure, you create a contact between the two layers.
00:03:38
In addition to this, there's a small microelectric component which has been miniaturized as much
00:03:42
as possible, so that it disrupts the cloth as little as possible, because the goal is
00:03:48
to preserve the characteristics of textiles, suppleness and comfort.
00:03:53
Suppleness and comfort, those are the watchwords for functional and intelligent clothing.
00:04:02
Yvette Rochester is in charge of the microbiology lab at the center.
00:04:07
She unlocks the secrets of textiles using this giant microscope.
00:04:11
Her research helps build an understanding of how fibers react to the presence of certain
00:04:16
nanoparticles.
00:04:21
For example, cosmetic nanoparticles that release perfumes into clothes.
00:04:22
These are microcapsules which contain a perfume that's integrated within the fibers that make
00:04:34
up the cloth.
00:04:40
What we've been looking at here is how uniformly the microcapsules are spread across the cloth.
00:04:42
And also, we wanted to have an idea of their dimensions.
00:04:50
And then, after the material's been used, we wanted to see how the microcapsules react.
00:04:54
They're supposed to explode and release their perfume.
00:05:00
And in fact, what we've seen here is that there are indeed microcapsules that have exploded
00:05:04
and thus released their perfume.
00:05:09
At the Institut Francais du Textile et Habillement outside Lyon, intelligent textiles are tested
00:05:13
for resistance against heat, flames, tearing, liquids.
00:05:19
Engineers work on several Europe-wide projects and also invent their own textiles for the
00:05:28
future.
00:05:33
Once the concept has been established, the cloth is modeled to a chosen design.
00:05:35
And added to a virtual collection of tomorrow's fashion.
00:05:46
For dreams to become a reality, you need a plasma machine like this.
00:05:51
Here in a vacuum, textiles are put in contact with different gases, oxygen, nitrogen, fluoride
00:05:58
or ammonia.
00:06:03
In this way, researcher Jacques Magouin changes the textile properties.
00:06:05
Fluorides, for example, make normally absorbent cotton impermeable, while nitrogen makes normally
00:06:09
resistant materials absorbent.
00:06:14
Nitrogen will separate off and try to impregnate itself in the textile.
00:06:19
So using nitrogen gas, you can make a kind of water plasma, which will attach itself
00:06:23
to the surface.
00:06:27
And when you put water next to this, there's a very strong affinity, and that makes a material
00:06:29
that absorbs very easily, which is good for cleaning materials, or for absorbing sweat,
00:06:33
or for sticky materials, or for printable materials.
00:06:37
On the other hand, fluoride gas makes cotton water-resistant, so when it rains, it's impermeable,
00:06:41
but still comfortable.
00:06:46
In these workshops, a European program to make threads of the future is being researched.
00:06:49
Christophe Angeloz is developing polypropylene thread that resists high temperatures.
00:06:54
The polypropylene is mixed with chemical microparticles whose composition is a commercial
00:07:00
secret.
00:07:04
The mixture is pummeled, melted, stretched, and woven into yarn.
00:07:05
It's all polypropylene, but by changing the manufacturing conditions, like the extrusion
00:07:14
temperature, the weaving speed, the stretching tension, you can optimize the thread production.
00:07:21
Threads which, like others made at the center, will now undergo testing to see if they might
00:07:34
be useful in the creation of the new intelligent textiles of the future.
