Lotus effect: nanotechnology for textiles

Nanotechnology is a high-tech process that makes it possible to apply naturally occurring qualities to materials. Thanks to this innovation we can obtain water-repellent fabrics.

It all began when the so-called lotus effect was discovered.

What is the lotus effect?

We have probably all seen the lotus flower at least in photographs: large petals, white to pink in colour, resting on large, flat, round green leaves; and on these leaves, large drops of water.

This flower grows in wet and muddy environments, real swamps, and you would expect to see leaves just as dirty and wet: however, the leaves of the lotus flower always remain dry and clean.

This is due to the special structure of the leaf surface. This is due to the special structure of the leaf surface. Apparently smooth, this surface actually has microscopic ripples that are invisible to the naked eye.

On surfaces with a normal structure, the water droplets adhere and then slide, allowing dirt to penetrate; on these tiny ripples, the water droplets do not slide, but roll, taking the dirt particles with them.

Nanotechnology fabrics: innovation and practicality

Once this extraordinary natural property has been discovered, nanotechnology enters the field. It allows this lotus effect to be imitated, resulting in water- and stain-repellent fabrics.

Nanotechnology is not a superficial coating, but acts deep down at the molecular level, so the fabric retains all its natural characteristics: it is non-toxic, breathable, antistatic, resistant to both wet and dry cleaning, allows faster drying and is easy to clean with neutral products, thus avoiding the use of toxic and polluting chemical solvents.

The treatment is also permanent and maintains the quality of the colours and fabrics over time.

How to remove stains from a nanotechnology fabric

This technological innovation reveals itself in all its practicality when a liquid is spilled on a fabric.

Depending on the situation, it will be necessary to act in two ways:

  • If the liquid has remained on the surface: to remove the stains, dab lightly with a dry cloth or kitchen paper.
  • If dirt has penetrated due to strong pressure: lightly rub the stained area with a damp, non-abrasive sponge and rinse with a clean sponge.

For washing, use a small amount of neutral detergent and rinse thoroughly. When completely dry, iron at a medium temperature. In any case, just follow the instructions on the fabric label carefully.

Nanotechnology fabrics for sofas and armchairs

Sofas, armchairs and all upholstered furniture are obviously “natural targets” for staining liquids: wine, coffee, soft drinks, to name but a few. And so upholstery fabrics are the natural field of application for nanotechnologies that exploit the natural properties of the lotus effect.

The nanotechnological stain-resistant finish can be applied to any fabric, which will retain its natural characteristics and at the same time acquire water-repellent properties.

Fabric colorfastness: quality that lasts

The dyeing process of our items ensures a perfect fabric colorfastness. For quality products that meet the needs of you and your customers.

The comfort of a removable cover

Those who buy a removable sofa certainly do so for the convenience of being able to put the cover in the washing machine. And machine washing is done not only to remove particular stains from time to time, but also to periodically refresh the covers and seat or back cushions, for example. So it’s critical to ensure the fabric colorfastness over time for that upholstery.

The dyeing process

Sofas, armchairs and other upholstered furniture made from fabrics that have not been dyed properly can lead to unpleasant surprises: when the upholstery is put into the washing machine, it is faded, the color has lost its brilliance and uniformity – sometimes even after just one wash. In order to ensure that the fabric’s color holds up perfectly, every step of the dyeing process is important, so that the color penetrates deeply into the fibers and is firmly fixed.

The characteristics of a good fabric

Fullness, uniformity, brightness, durability: these are the essential characteristics of the color, and that a good fabric must have and must maintain over time to be used in the production of sofas, armchairs and upholstered furniture quality. In order to obtain these characteristics, the dyeing process of Cartex Italia’s fabrics, in yarn or in piece, is entrusted to partners who have shown professionalism, reliability and timeliness over the years.
