Embodiment 1

[0039] According to the conventional melt-blown process, the polymer used is polypropylene chips; after the polypropylene chips are fed and melt-extruded, in the process of fiber formation, a stream containing nano-tourmaline powder is introduced from both sides of the hot air flow These nano-tourmaline powders are mixed with polypropylene microfibers that are being thinned in the hot air flow. At the same time, under the hot air flow, the solution containing chitosan derivatives is atomized and sprayed evenly On the polypropylene superfine fiber, these substances are sprayed to the net-forming chain at the same time, condensed into a net, and the hot air or part of the water vapor is sucked away through the suction at the bottom of the net, and then passed through a drying roller with a temperature not exceeding 100 degrees and a cold water stick , and then rolled into cloth.

[0040] Wherein weight ratio, polypropylene: tourmaline powder: chitosan derivative=94: 3: 3;

experiment example

[0049] The melt-blown nonwoven material prepared by the above-mentioned embodiment 1 and embodiment 2 was subjected to a filter efficiency detection experiment, an antibacterial detection experiment and an anion release test experiment by conventional methods. The results show that while the resistance is controlled within 5 mm of water column, the filtration efficiency can reach more than 99.9%, and the anti-hemodialysis can reach 160 mmHg, as shown in the following table:

Abstract

The invention discloses a melt-down non-woven material, a preparation method and a product thereof. The material comprises polymer fibers, nanometer tourmaline powder and a chitosan antibacterial agent. The melt-down non-woven material has antibacterial and health-care effects; the filter efficiency of the material reaches over 95 percent; the antibacterial ratios of the material to staphylococcus aureus, Escherichia coli and Candida albicans are all over 99 percent; and the material can continuously release oxygen negative ions, wherein the melt-down material with an area of 100 cm<2> can release approximately 200 negative ions per cubic meter around the material.

Description

technical field [0001] The invention relates to the field of nonwoven materials, in particular to a melt blown nonwoven material, a preparation method of the material and a product prepared from the material. Background technique [0002] Meltblown nonwoven technology is a kind of polymer one-step cloth forming technology. Melt-blown nonwovens (melt-blown non-woven fabrics) can be widely used in filter materials, medical materials, sanitary products, oil-absorbing materials, clothing materials, wiping cloths, hot-melt adhesive materials, electronic special materials (battery batteries, battery compartments) etc.), special fibers, etc., have broad application prospects. The process of conventional melt-blown nonwoven materials is: polymer feeding→melt extrusion→fiber formation→fiber cooling→web forming→reinforcement→edge trimming and coiling→finishing or special finishing. [0003] When melt-blown non-woven fabrics are used as filter materials (including mask materials), it...
