Embodiment 1

[0019] Also disclosed is a production process for inactivated germ melt-blown cloth, comprising the following steps:

[0020] S1: Pre-preparation of raw materials: Prepare 75kg of polypropylene PP-1500, 2.5kg of zinc oxide and 3.5kg of cuprous oxide and put them into the mixing tank for 40 minutes and stir for later use;

[0021] S2: Melt spraying: The spare raw materials are heated and plasticized by the main screw machine, then accurately quantified by the metering pump, and then sprayed on the mesh belt receiver through the melt blown nozzle;

[0022] S3: Melt-blown cloth forming: the melt is evenly sprayed on the mesh curtain by high-temperature air pressure through the mold spinneret, and the bottom of the mesh curtain is collected and formed by a negative pressure fan;

[0023] S4: Stationed in static electricity: the formed melt-blown cloth is transported by the mesh curtain to the electrostatic electret equipment, and the electrostatic electret cabinet is used for the ...

Embodiment 2

[0028] A production process of a melt-blown cloth for inactivating germs, comprising the following steps:

[0029] S1: Pre-preparation of raw materials: prepare 115kg of polypropylene PP-1500, 7.5kg of zinc oxide and 9.5kg of cuprous oxide and put them into the mixing tank and stir for 80 minutes for standby;

[0030] S2: Melt spraying: The spare raw materials are heated and plasticized by the main screw machine, then accurately quantified by the metering pump, and then sprayed on the mesh belt receiver through the melt blown nozzle;

[0031] S3: Melt-blown cloth forming: the melt is evenly sprayed on the mesh curtain by high-temperature air pressure through the mold spinneret, and the bottom of the mesh curtain is collected and formed by a negative pressure fan;

[0032] S4: Stationed in static electricity: the formed melt-blown cloth is transported by the mesh curtain to the electrostatic electret equipment, and the electrostatic electret cabinet is used for the electret pro...

Embodiment 3

[0037] A production process of a melt-blown cloth for inactivating germs, comprising the following steps:

[0038] S1: Pre-preparation of raw materials: Prepare 95kg of polypropylene PP-1500, 5kg of zinc oxide and 7kg of cuprous oxide and put them into the mixing tank and stir for 60 minutes for standby;

[0039] S2: Melt spraying: The spare raw materials are heated and plasticized by the main screw machine, then accurately quantified by the metering pump, and then sprayed on the mesh belt receiver through the melt blown nozzle;

Abstract

The invention discloses an inactivated germ melt-blown fabric. The inactivated germ melt-blown fabric comprises the following components in parts by weight of 60-150 parts of polypropylene PP-1500, 1-9 parts of zinc oxide and 2-18 parts of cuprous oxide; the invention also discloses a production process of the inactivated germ melt-blown fabric, which comprises the following steps of S1, raw material pre-preparation treatment: preparing 80kg of polypropylene PP-1500, 2.5 kg of zinc oxide and 4.5 kg of cuprous oxide, uniformly putting the raw materials into a stirring barrel, and stirring for 40-80 minutes for later use, and S2, melting and spraying: heating and plasticizing the standby raw materials through a main screw machine, then accurately quantifying through a metering pump, and spraying a melt onto a mesh belt receiver through a melt-blowing nozzle. Zinc oxide and cuprous oxide in the non-woven fabric have a good sterilization effect on escherichia coli, klebsiella pneumoniae and staphylococcus aureus, and the sterilization effect is far beyond the existing sterilization standard.

Description

technical field [0001] The invention relates to the technical field of production of antibacterial nonwoven fabrics, in particular to a melt-blown fabric for inactivating germs. Background technique [0002] With the development of industrialization, the increase of population, the increase of harmful substances in the air, and the smog becoming more and more serious, the traditional mask cloth can no longer meet people's needs. Therefore, an antibacterial melt-blown non-woven fabric is urgently needed. Contents of the invention [0003] In order to achieve the above object, the technical scheme that the present invention takes is: [0004] A meltblown cloth for inactivating germs, comprising the following components by weight ratio: 60-150 parts by weight of polypropylene PP-1500, 1-9 parts by weight of zinc oxide and 2-18 parts by weight of cuprous oxide. [0005] Further, 70-120 parts by weight of polypropylene PP-1500, 2-8 parts by weight of zinc oxide and 3-10 parts ...
