Abstract
The invention discloses a production process of a non special -woven fabric for a facial mask. The production process comprises the following steps that raw materials including dacron, nylon and polyethylene are prepared according to a weight ratio being (10-20):(30-40):(30-50); the dacron and nylon raw materials are uniformly mixed and stirred; the mixed materials are melted and compressed by a screw extrusion machine into viscous flow state melts, and the melts are respectively conveyed to a melt filer through a melt pipeline to be filtered; the filtered raw materials are respectively conveyed into a spinning die head; a fine melt flow is extruded from a spinning hole and is then cooled, drafted and shaped to form fiber through a drafting air passage under the effect of process cooling air; then, through a diffusion air passage, the fiber is uniformly adsorbed onto a net forming conveying belt, and a continuous reticular fiber layer is formed; the continuous fiber nets pass through a hot rolling mill, and the fabric nets form non-woven fabrics; the cloth is subjected to softening treatment through softening agents. The production process has the advantages that no stimulation is generated on the skin, silk protein liquid can be better adsorbed, and meanwhile, the ventilation performance is good.
