Notes:
A method is described by which the UK Upholstered Furniture (Safety) Regulations of 1980 may be complied with. By coating the surface of flexible polyurethane foam with vinylidene chloride copolymer latex, a fire retardant surface is obtained. This enables most fabric/foam combinations to pass both the cigarette and the match tests as laid down in BS5852. The coating process can be carried out with a brush, a roller or by spraying. Drying can be at room temperature or by using heat and/or a forced draught. Using about 350 gm-2 only certain deep-pile fabrics fail, and even hen additionally back-coating them with PVDC can ensure compliance. The presence of thin wadding or stockingette makes no difference, but thick wadding will burn with the fabric for more than the mandatory two minutes without setting fire to the PU foam. Fabrics successfully tested with the coated PU foam include cottons, polypropylene, acrylic, polyester and ‘Dralon’. After 80 000 indentations in a standard test the coating was still effective, as it was also after heating in a detergent for 4h.
