[0027] The preparation method of described antibacterial nonwoven fabric, comprises the following steps:

[0028] S1. Mix polypropylene, nano-silver ion, n-butanol, polyvinylpyrrolidone, ethoxylated alkylamide, n-butanol, polyvinylpyrrolidone and ethoxylated alkylamine, and then add nano-silver Mix the ions evenly, heat up to 60-70°C, keep warm for 1-2h, stir at 650-850r / min for 1-2h, cool to room temperature to obtain the base material;

[0029] S2. Heat the base material to 52-58°C, then add nano-zinc borate, palygorskite, bamboo fiber, inorganic germanium powder and polyethylene terephthalate and mix evenly, heat up to 60-70°C, and keep warm for 1 -3h, keep stirring during the heat preservation process, then add anti-mildew modified filler, anti-bacterial modified additive and silane coupling agent KH-570 and mix evenly, continue to heat up to 80-90°C, at 650-850r / min Stir and disperse for 1-2 minutes to obtain the modified material;

[0030] S3, winding the bamboo fiber ...

Abstract

The invention discloses an antibacterial non-woven fabric. The non-woven fabric is prepared from glass fiber, polypropylene, graphene, copper oxide, nanometer silver ions, n-butyl alcohol, polyvinylpyrrolidone, ethoxylation alkyl acid amide, nanometer zinc borate, palygorskite, bamboo fiber, inorganic germanium powder, polyethylene glycol terephthalate, mold-proof modified filler, antibacterial modified auxiliaries and silane coupling agent KH-570. The invention further discloses a preparation method of the antibacterial non-woven fabric. The non-woven fabric has the excellent mold-proof and antibacterial performance.

Description

【Technical field】 [0001] The invention belongs to the technical field of non-woven fabric preparation, and in particular relates to an antibacterial non-woven fabric and a preparation method thereof. 【Background technique】 [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing The formed non-woven fabric is a new type of fiber product with soft, breathable and planar structure. The advantage is that it does not produce lint, is strong, durable, and silky soft. It is also a kind of reinforcing material. [0003] Chinese patent application document "An antibacterial composite nonwoven fabric and its preparation method (application publication number: CN107685512A)" discloses an antibacterial composite nonwoven fabric, including glass fiber, bamboo fiber, po...
