Abstract

The invention relates to a method for preparing anion spun-bonded non-woven cloth. The method includes the following steps that an anion parent material is prepared, wherein silicon dioxide, tourmaline, attapulgite, zirconium dioxide, phosphorus pentoxide, aluminum oxide and rare earth ore are forged, smashed and evenly mixed; the anion parent material, inorganic powder, carrier resin, lubricating agent, dispersion agent and coupling agent are placed in a stirring machine to be stirred and prepared into a non-woven cloth mixed material; the non-woven cloth mixed material is added into an extruder to be extruded and subjected to die surface hot cutting to obtain spun-bonded non-woven cloth slices; the spun-bonded non-woven cloth slices are sequentially subjected to melted extrusion modeling, filtering, spinning, cooling and stretching to obtain continuous filaments; the continuous filaments are arranged and spread to form a net, and the anion spun-bonded non-woven cloth is obtained after curing. The anion release amount of the anion spun-bonded non-woven cloth prepared through the method is greatly increased.

Description

technical field [0001] The invention relates to the technical field of spunbonded nonwoven fabrics, in particular to a preparation method of negative ion spunbonded nonwoven fabrics. Background technique [0002] Negative ion is a kind of far-infrared radiation material that is very beneficial to human health. The optimal wavelength of far-infrared rays suitable for human body absorption is 9.6 μm, while the wavelength of far-infrared rays radiated by negative ion mineral crystals is in the range of 2-18 μm, and the radiation power emission density is 0.04w / cm 2 Slightly higher, the above data can fully prove that the far-infrared rays radiated by negative ion mineral crystals are well coordinated with the human body and can be completely absorbed by the human body. In the medical field, negative ions are recognized as an effective means of killing germs and purifying the air. [0003] Negative ion spunbond non-woven fabrics can be widely used in medical and sanitary cloth...
