The invention provides an automobile trim material combined with a non-woven fabric and a woven fabric The automobile trim material is prepared by virtue of the following steps: 1, cutting ramie into 70mm fibers, putting the fibers into a stainless steel vessel, adding a sodium bicarbonate solution and stirring for 60 minutes; 2, cleaning jute fibers and drying the jute fibers; 3, adding warm water at a temperature of 30 DEG C, performing constant-temperature bath for 60 minutes, adding 1% constant temperature bath and 0.1% ceric ammonium nitrate, cleaning, and then drying; 4, putting the jute fibers on fur machine equipment, and performing shredding mixing on the jute fibers and polypropylene fibers; 5, carding the fibers into a net shape by use of a carding machine; 6, paving the fibers to form a multilayer net body with weight per square meter of 1500g; 7, paving polypropylene fabrics on both sides as surface layers, and performing reciprocating reinforcement by use of a needling machine; and 8, pressing to prepare an automobile trim material sectional material by use of die pressing equipment. The automobile trim material produced by the method is low in price, is capable of adsorbing sound and insulating heat, is high in rigidity, durable in use, simple in technological process and free from environmental pollution.

The invention discloses a flame-retardant modified ramie fabric/benzoxazine resin laminated board. The laminated board comprises multiple layers of assembling units. Each layer of assembling unit comprises an internal ramie fabric layer and a bonding layer on the surface of a ramie fabric, wherein the outer surface of the ramie fabric layer is coated with a titanate layer or a titanate layer and 10-30 fire retardant layers, the bonding layer is a mixed catalyst containing benzoxazine resin bonding layer, and the mixed catalyst is composed of methyl p-toluenesulfonate and acetylacetone ferric salt. The laminated board has a good flame-retardant effect, can have good mechanical properties and heat resistance at the same time and is good in comprehensive performance.

The invention relates to an anti-static fabric with good using properties. The fabric comprises a fabric main body (1). The upper surface of the fabric main body is provided with an anti-radiation layer (2). The upper surface of the anti-radiation layer (2) is provided with a reinforcing layer (4). The upper surface of the reinforcing layer is provided with an anti-static layer (8). The lower surface of the fabric main body (1) is provided with an antibacterial layer (5), a fireproof layer (6) and a waterproof layer (7). The lower surface of the waterproof layer is provided with a liner layer. The liner layer is formed by weaving weft. Warp and the weft adopt kapok fibers and ramie fibers respectively, wherein the diameter of the kapok fibers is 4.16 mum, the diameter of the ramie fibers is 18.32 mum, the warp density is 16.9 lines per cm, and the weft density is 26.7 lines per cm. The fabric is good in using properties.
