PasserelleTM improves the moisture management,

handle, and comfort characteristics of natural

and synthetic fibres.

Passerelle™ enhances the absorbing properties of fabrics

by creating a highly water-absorbing surface.

Measuring the absorbency

Fabrics are placed on a water surface for 10 seconds and

reweighed to calculate water absorbency

A fabric treated with Passerelle™ is able to absorb up to 10-

times the amount of water compared with an untreated

fabric

PropertiesProperties

• Rapid absorbency and evaporation of moisture is key to

maintaining comfort.

• Passerelle™ treated fabrics show an enhanced rate of

drying due to superior absorbency and wicking

properties.

• Passerelle™ treated fabrics help to maintain thermal

comfort by controlling moisture in the fabric.

PropertiesProperties

Passerelle™ is a non-silicone, hydrophilic, durable finish.

Imparts a natural handle.

Imparts a feeling of volume to fibres e.g. towels.

On synthetics, drape and wearability is improved.

Imparts breathability to fabric which improves comfort.

Unique patented chemistry.

PropertiesProperties

• Water droplet – simple, quick and can be easily demonstrated.

• Wicking – vertical movement of water, construction dependent.

• Evaporation – particularly for performance fabrics, requires accurate measurement, horizontal movement of water.

• Drying Time – vertical movement of water, alternative to evaporation, gives profile of water lost from fabric surface.

• Spreading – water movement across a fabric surface.

• Water absorption – water affinity test, particularly applicable to heavy or voluminous fabrics e.g. fleece.

Test methodsTest methods

• A droplet of water is placed on flat fabric (face

up).

• The time taken for the

droplet to completely penetrate into the fabric

is recorded up to a maximum of 60 seconds.

Water Droplet

TM

Test methodTest method

• Vertically suspend fabric samples so that

bottom is just touching water surface.

• Measure the distance travelled

by the water during a set period

of time.

• Measure performance in both

warp and weft direction.

Wicking

TM

Test methodTest method

• Very simple to carry out.

• Apply 1 ml of water and measure the

maximum diameter of spread after 1

minute.

Spreading

TM

Test methodTest method

• Circle of fabric 10 cm in diameter

• Place on to the surface

of water in a beaker for

• 10 seconds then

accurately weigh the pick

up of water.

Test methodTest method

• Fabric samples are wet out

accurately.

• Samples then hung

vertically and weighed

every five minutes until a
