ADDING LOGOS

Adding company logos to workwear is a common request, and Tranemo delivers around 100,000 logo-bearing garments each year. Before adding logos to flame retardant clothing it is important to know that garment certifications impose requirements on various types of marking, and the wrong solution can reduce the protection provided by a garment. Heat seal badges, sew-on badges or embroidery that cover an area less than 10 cm² do not require flame retardant testing under the EN ISO 14116 standard.

 

HEAT SEAL BADGES

For heat seal badges, Tranemo uses InduTrans 15FR, an all-round heat seal material that works on most fabrics and meets the requirements of EN ISO 14116 Index 3 when applied to Tranemo’s flame retardant fabric. A heat seal badge retains heat for longer than the fabric when exposed to high temperatures. From a safety viewpoint it is therefore recommended that large, unbroken areas of heat seal material are avoided. The best area to apply a heat seal badge is where there are several underlying layers of fabric that will help to protect the skin. Heat seal badges provide 99% coverage on dark garments and can be washed at 60°C and tumble-dried at low temperatures (garment should be washed and dried inside out).  

 

SEW-ON BADGES

Sew-on badges for flame retardant garments must be made from a flame retardant fabric. The EN 1149-5 standard requires that sew-on badges are permanently attached.

 

EMBROIDERY

If a flame retardant garment is to be embroidered directly, flame retardant embroidery thread must be used.

LOGOS ON HIGH VISIBILITY GARMENTS

High visibility garments that are certified to EN ISO 20471 must always have a minimum area of fluorescent fabric, and garments are certified in different visibility classes depending on the size of this area. To avoid reducing the fluorescent surface area, logos should be placed on an area of contrasting colour or be kept relatively small. Tranemo recommends that logos are not placed on the fluorescent surface at all. The same recommendation also applies to upper garments that are certified to EN ISO 20471 and have a relatively small fluorescent area (e.g. short-sleeved garments, women’s garments or garments that have a large proportion of non-fluorescent fabric).
If unsure, contact Tranemo for help in calculating the high visibility area of an individual garment and any restrictions that apply.
