Elastic inflaming-retarding composite fabric and preparation method and application of same

The invention discloses an elastic inflaming-retarding composite fabric which comprises a superficial layer, an elastic layer and a lining layer, wherein the superficial layer and the lining layer are respectively adjacent to the upper and lower faces of the elastic layer and adhered by an inflaming-retarding adhesive; and the superficial layer is made of an inflaming-retarding polyester fabric, the elastic layer is made of an inflaming-retarding thermal-insulation elastic polyester coiled material, and the lining layer is made of inflaming-retarding non-woven cloth. The invention also discloses a preparation method and an application of the elastic inflaming-retarding composite fabric. The elastic inflaming-retarding composite fabric provided by the invention is inflaming-retarding permanently, wherein a Limiting Oxygen Index (LOI) is no less than 32%, a smoke density level during combustion is not higher than 50, and toxicity of generated smoke is not lower than level ZA2. The elastic inflaming-retarding composite fabric has good rebound resilience and is applicable to interior decorations, seat covers and the like of traffic tools.
