Nikola Schwaiger & Shufei Wang Borås, 26. May 2010 2 Abstract The field of protective garments is a wide range segment, and protective clothings are needed in the daily business of workers, for example fire fighters, police men, and in the fishing industry. This Master-Thesis focuses on properties of fire fighters protective garments and other work wear in combination with luminescent materials and future challenges. The research is based on a market research through interviewing fire- fighters and all important manufacturers along the supply chain. It analyzes the market demand of new fire-garments with both fire retardant and luminescent functions; provides an overview over current available materials, and explains the future possibilities for those garments; gives a suggestion of possible supply chain as well as the product design. Some relevant standards and tests were also described; major impacts that protective clothing has to withstand are thermal heat, biological, chemical, and also mechanical impacts; in this context, the properties of flame retardant and luminescent materials are worked out. From technical point of view, it seems to be possible to combine flame retardant and luminescent material together on protective garment, though still lots of research work needs to be done to ensure the combination can meet high standards. However, other work-wear is a potential field for the application of luminescent material, for example road-workers, sports wears, etc. 3 Table of content Introduction Aim Methods Delimitation 1 The partner F.O.V. fabrics AB ...................................................................... 12 2 Luminescence ............................................................................................. 14 2.1 Luminescence in general ................................................................................... 14 2.2 Photo-luminescence ......................................................................................... 15 2.2.1 Fluorescence ........................................................................................ 16 2.2.2 Phosphorescence ................................................................................. 17 2.3 Material properties of phosphorescent materials ............................................ 19 2.4 Field of application ............................................................................................ 19 3 Flame retardant materials today ................................................................. 22 3.1 Definition of flame retardant material ............................................................. 22 3.2 Materials & producing companies .................................................................... 22 3.2.1 Kevlar ®/ DuPont.................................................................................... 23 3.2.2 Nomex ®/ DuPont .................................................................................. 23 3.2.3 Lenzing FR ® ........................................................................................... 23 3.2.3.1 Standards and testing .......................................................................... 25 3.2.3.2 Company size and capacity .................................................................. 25 3.2.3.3 Customers and application field .......................................................... 25 3.2.3.4 Comparison to other fibers .................................................................. 26 3.2.4 PBI ® ....................................................................................................... 26 3.2.5 Twaron ® ................................................................................................ 27 3.3 Material properties ........................................................................................... 27 3.4 Field of application of flame retardant materials ............................................. 27 4 EU Standards and Norms of illuminating and flame retardant material ........ 28 4.1 EN 469 protective clothing ................................................................................ 28 4.1.1 EN 433, 3.17 accessory ........................................................................ 30 4.1.2 EN 433, 3.29 trim ................................................................................. 30 4.1.3 The old German standard DIN 14940 for helmets ............................... 30 4.2 EN 471 High Visibility ........................................................................................ 31 4.3 Certificates ........................................................................................................ 31 5 Textile tests after the EU Standards ............................................................. 32 5.1 Mandatory textile tests related to DIN EN 469................................................. 32 5.2 Additional possible tests ................................................................................... 35 5.3 Fluorescent or reflective applications and accessory materials ....................... 36 5.4 Mandatory textile tests related to DIN EN 471:2008-03 .................................. 36 4 5.5 Tests for finished garment ................................................................................ 37 6 Market research ......................................................................................... 38 6.1 Chemistry industry ............................................................................................ 38 6.2 Testing institutes ............................................................................................... 39 6.3 W.
