(3) Beneficial effects
Compared with the existing technology, the present invention provides a flame-retardant breathable fabric and a preparation method thereof, which has the following beneficial effects:
1. The present invention selects modified ramie fiber with good air permeability as the main fiber to ensure the air permeability and heat dissipation performance of the base fabric. By adding polyester fiber, the shape retention of the base fabric is improved, and the ramie fiber is modified to improve the heat dissipation performance. Its elasticity, cohesion and spinnability.
2. The present invention forms a double flame-retardant protection mechanism through the surface layer of heat-insulating flame-retardant fabric and the flame-retardant compound applied on its surface, which greatly increases the flame-retardant performance of the fabric. At the same time, the silk antibacterial and breathable fabric is woven from natural cocoon silk. It has good breathability and flame retardant properties.
3. The flame-retardant compound in the present invention is a linear polymer with a large relative molecular weight, low mobility, excellent flame-retardant performance and durability, and the cage-like phosphate ester structure in the flame-retardant compound is more likely to be enriched on the surface of the composite material , forming a dense protective carbon layer to prevent dripping or holes, further improving the flame retardant performance of the flame retardant layer.
