Developments in flame‐retarding polyester/cotton blends

The burning behaviour of polyester/cotton blended fabrics is discussed and possible flame‐retardant strategies outlined. Particular attention is paid to the effectiveness of phosphorous‐ and nitrogen‐containing and antimony(III) oxide/halogen flame‐retardant systems. Recent developments within the UK are discussed which suggest that phosphonium salt condensate finishes are effective on cotton‐rich blends and that antimony‐halogen systems may be used on all polyester/cotton blend compositions. Both types of flame retardant have acceptable durability to laundering
