Abstract

The invention discloses a high-strength flame-retardant elastic fabric and a preparation method thereof, and belongs to the technical field of fabric and processing thereof. The preparation method includes co-reacting layered hydroxide, sodium alginate and ammonium polyphosphate to obtain modified microspheres, blending the modified microspheres with the polytrimethylene terephthalate for extruding, carrying out melt extrusion with polyethylene terephthalate to obtain an extruded material, spinning and cooling the extruded material, drawing to obtain a composite fiber, mixing the composite fiber with dopamine hydrochloride solution, adding graphene oxide, mixing and soaking to obtain a composite flame-retardant fiber, and finally weaving the composite flame-retardant fiber into a fabric that is the high-strength flame-retardant elastic fabric. The high-strength flame-retardant elastic fabric prepared by the invention has excellent flame retardance and breaking strength.

Description

technical field [0001] The invention relates to the technical field of fabrics and their processing, in particular to a high-strength flame-retardant elastic fabric and a preparation method thereof. Background technique [0002] With the development of society, people's requirements for fabrics are increasing, especially in special occasions. In the final analysis, the flame retardant performance of the fabric depends on the flame retardant performance of the fabric fibers. [0003] Flame-retardant fiber refers to the fiber that cannot burn or burns insufficiently after contact with the fire source, and only has a small flame. When the fire source is removed, the flame can extinguish itself quickly. Currently commonly used flame retardant fibers are: PBI fiber, PVC fiber, PTFE, PPTA, Prylanitz fiber, polyamide-imide fiber. Among them, Prylanitz fiber, because of its good hygroscopicity, does not melt under the action of radiant heat or flame, so it can be used in the water...
