Novel Light Flame-Retardant Heat-Insulated Warm-Retention Protective Fabric and Preparation Method Thereof

Abstract

The present application discloses a novel light flame-retardant heat-insulated warm-retention protective fabric and a preparation method thereof. The preparation method comprises the steps of making soluble fibers and wrapping fibers into core spun yarns by ring spun core-spun spinning method, and weaving the made core spun yarns into a grey fabric by a loom; and then dissolving the soluble fibers in the grey fabric, and finally making the grey fabric into the novel light flame-retardant heat-insulated warm-retention protective fabric upon dyeing and finishing procedures. The protective fabric is a hollow yarn fabric and includes conventional woven goods and knit goods, still air will be generated among the yarns. With respect to the protective fabric with flowing air in the prior art, the protective fabric of the present invention has the advantages of better heat insulation and warm retention, lighter weight and stronger comfort.
