Thirdly, polyurethane coatings (PUR) are a conventional alternative to the membranes as regards water tightness and breathability.
Techtextil fair which runs from May 4-7, 2015 in Germany will see a strong line up of suppliers of personal protection equipment, clothing and #
Usually the reverse side of the fabric is coated thus allowing the fabric to provide an exchange of humidity and concurrent water tightness.
The textiles manufactured in such a way are less expensive than any of the membrane variants. In addition, they allow more flexibility regarding the choice of the shell and its character.
However, the disadvantage is that the coatings have less stability against loading which has to be taken into account in linen rental services.
Experiments are being carried out with flame resistant admixtures with the aim of obtaining a wider applicability.
Polyurethane coatings in the form of various sorts of synthetic leather are used on the front side of goods such as work shoes and safety shoes and they are sturdy and easy to clean.
Next are the phase change materials (PCM) and nanotechnology offered by Outlast as one of the most established suppliers in the form of surface printing, coatings or any other fibre matrix.
The used paraffin like substances are embedded in micro spherules change from solid to liquid under temperature influence.
For the phase change into fluid, the increased heat is absorbed and virtually stored in order to preserve this condition and while being cooled down, the material gets solid again whilst the heat is released slowly.
A temperature balance is created that avoids peaks towards excessive heat and cold so that comfort does not get lost, by which an excessive production of sweat is prevented.
Thanks to the modular or layer-wise structure of the temperature-regulating systems it is possible to have clothing which has features like weather protection, protection clothing, flame resistance, welder’s protection and protection against fault arcing or electrostatic discharge.
The most important standard mostly dictates the choice of the outer layer and the structure of the entire system as in case of work under heat exposure.
Suppliers are working intensively on the task to shape as flexible as possible the number of single components for the range of personal protection equipment and work protection clothing.
Companies among them like Sympatex, Outlast, Transtextil and Schoeller will exhibit their latest developments of multifunctional protection systems at Techtextil. (AR)
