▎ 摘　　要

NOVELTY - The fabric comprises a composite nonwoven fabric substrate layer, an outer flame-retardant layer, and an outer water-resistant layer from the inside to the outside. The composite nonwoven fabric substrate layer comprises first and second modified non-woven fabric substrate layer. The first modified non-woven fabric substrate layer comprises 65-70% first non-woven fabric, 25-27% first modified non-woven auxiliary material, and 3-10% nonwoven fabric composite adhesive. The first non-woven fabric main material is composed of viscose fiber, chinlon, and polyvinyl acetal fiber. The first modified non-woven auxiliary materials is composed of polypropylene fiber, and polyvinyl formal fiber. The second modified non-woven fabric substrate layer comprises 25-32% second modified non-woven fabric auxiliary materials, 8-15% nonwoven fabric composite flame retardant, 0.3-0.8% auxiliary agent, and second non-woven fabric material. USE - Used as flame retardant nonwoven fabric based on modified technology. ADVANTAGE - The flame-retardant nonwoven fabric uses the first modified non-woven fabric substrate layer; the second modified non-woven fabric substrate layer forms the matrix mother layer; the raw material contains flame retardant to satisfy the flame retardant property; and further using the outer flame retardant layer to enhance the flame retardant property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of flame-retardant nonwoven fabric.
