Textiles, flame retardancy design

Most flame-retardant finished textiles are excluded from the Oko-Tex Standard 100 label. In all cases, the durability of the finish is often a problem. It is the responsibility of the fabric finisher to address these issues if commercial flame-retardant fabrics are to be produced. An alternative for the fabric designer without most of the named problems is the use of flame-resistant modified fibres, but... 

A special grade, FR-372 has been designed for PP fibre and textiles. The usual method of application is via a masterbatch containing 30-40% of flame retardant. This concentrate is then diluted in the PP to reach around 3-5% of FR-372 in the final composition. 

RoHS Since the Directive on the restriction of the use of certain hazardous substances in electrical and electronic eqnipment (cotmnonly referred to as the Restriction of Hazardous Substances directive of the RoHS directive) came into force in the European Union (EU) in Jnly 2006 [167]. Some of the same regulations on chemical management have been adopted in other parts of the world. The RoHS directive restricts the amount of PBBs and PBDEs [168] contained in electrical and electronic equipment to less than 1000 ppm. No electronic electric apparatus can be marketed in an EU member state if it contains those materials in excess of a designated value of RoHS. PBBs and PBDEs are among the large variety of brominated flame retardants (BFRs) used in plastics and textiles. PBBs are no longer produced, but PBDEs were in widespread nse before the RoHS directive came into effect, and...
