Fluorescent pigment have four times greater visibility than similar nonfluorescent ones and this has led to applications demanding higher visual impact and consequently they play a major role iin safely , identification advertising and merchandise .
Fluorescent pigment has been used mainly for print use in textile, field ,however recently it has been frequently used for padding ,this due to diversifications in fashion and in the development of textile processing technology .with the expansion of sports and leisure specially in ski and marine sports it is becoming more widely used for clothing related to these fields
SAFETY & IDENTIFICATION :
Fluorescence is used in many fields for a wide range of safety and identification uses and some indication of the safety is given below
.
CIVIL:
Fluorescent products can be used for application ,police cars and ambulance marking safety clothing's for children .police and road workers and all other application high degree of visibility is essential .
INDUSTRIAL :
Fluorescent products are used for safety exits ,pipe lines fireetiguishers , valves ,danger areas ,hazard making ,protective clothing headgear and any other application where in stant recognition is vital .
MILITARY :
Fluorescent products are used marking aircraft ,naval vassals ,ground equipment ,landing equipment ,twotarget ,wind cones ,lift jackets and in many other articles where instant identification or rapid location is important .
Advertising and Merchandising:
The advertising and merchandising industries are always striving for maximum visual impact in their display .in this industry the end uses can be decoration ,direct mail ,counter and window display and packaging item ,price tags ,cinema ,posters ,stiles and now even in textiles .in short any item that needs to capture attention quickly . to achieve this wide range of fluorescent applications these pigment are used in poster paints, emulsion paints ,powder coating ,aircraft, automobile and marine finishes ,screen letterpress .rotogravures .fleographic .textile and packaging inks ,paper and cardboard coating ,fabric and plastic coating elastomer and rubber proofing and all types of molded plastics.
THE PHENOMENON OF SFLUORESCENCE :
the outstanding feature of fluorescent pigments is the basic principle of daylightfluoresence fluorescent pigments like ordinary conventional pigments . absorb white light with the exception of their self cooler which is reflected and seen however in addition fluorescent pigments also absorb ultra violet light and e-mail this as visible light corresponding too the fluorescent pigment shade in this way the pigments e-mail more visible light than they receive and consequently appear as very bright color even in poor daylight condition such as dusk and dawn .
CHEMISTRY:
The principal daylight fluorescent pigments are based on dilute solution of dyes such as phodamin or the aminonapthalimides preparation intrazine modified sulphomamideresin the resin type is an extremely triable organice glass that is found by co-condensing a toluene sulfonamide formaldehyde with trizine such melamine or benzo ・guanamine
BLEEDING IN SOLVENTS:
Procedure:500mg of the dry pigment powder is shaken with 20ml of solvent at room temperature for 10 minutes and than filtered through a no:42(equivalent )filter paper with barrytes bed . the colour of filtrate is observed (visually ) and rated as 5 if there is no bleed and 1 if the bleed is considerable with gradation in between .
VISIBLITY:
Fluorescent pigment are about four times more visible than the nearest and brightest non fluorescent colour and are most effective in condition of lighting dusk or down their relative visibility varies some what with the conditions under which they are seen the comparative table below includes a high reflective white paint and aluminum paint .
