Embodiment 1

[0042] A preparation method of a waterproof and breathable composite non-woven fabric. First, polyacrylonitrile, polyvinylidene fluoride, fillers, and water-soluble porogen are mixed and melted, and then sprayed out through a spinneret, air-drawn, formed into a web, and hot-pressed. Bonding, water immersion to remove the porogen, namely the composite non-woven fabric; wherein, the filler is prepared by the following method:

[0043] (1) earlier take zinc acetate, sodium tripolyphosphate, sodium hydroxide and porous tourmaline as raw material to make zinc oxide-tourmaline complex through solid phase reaction;

[0044] (2) Carry out epoxy modification to zinc oxide-tourmaline complex body then, then react with amino-terminated fluoropolymer, obtain modified complex body;

[0045] (3) Finally, immerse the modified complex in 1-allyl-3-methylimidazolium tetrafluoroborate for surface modification to obtain the filler.

[0046] The mass ratio of polyacrylonitrile, polyvinylidene fl...

Abstract

The invention belongs to the technical field of non-woven fabric products and in particular relates to a waterproof, breathable and bacteriostatic compound non-woven fabric and a preparation method and application thereof. The preparation method comprises the following steps of mixing and fusing polyacrylonitrile, polyvinylidene fluoride, stuffing and a water soluble pore-foaming agent; and then carrying out spraying by a spinneret plate, air flow drafting, net forming, hot-pressing bonding and water leaching to remove the pore-foaming agent to obtain the waterproof, breathable and bacteriostatic compound non-woven fabric, wherein the stuffing is prepared from raw materials: a zinc oxide- tourmaline compound, an amine-terminated fluorine-containing polymer and 1-allyl-1-3-methylimidazole tetrafluoroborate. The non-woven fabric has good waterproof and breathable properties and is excellent in antibacterial property.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabric products. More specifically, it relates to a waterproof, breathable and antibacterial composite nonwoven fabric, its preparation method and application. Background technique [0002] With the improvement of living standards, people's demand for disposable sanitary products such as baby diapers, adult diapers, and women's sanitary napkins is getting higher and higher, and their requirements for comfort and product quality are also getting higher and higher. [0003] Users of these disposable hygiene products include vulnerable groups such as infants, bedridden adults, and menstruating women. If the air permeability of sanitary products is not good, the skin of vulnerable people wrapped in sanitary products or in contact with the sanitary products for a long time will be in a humid environment for a long time, redness and rash may occur in mild cases, and mild or severe skin rashes may occ...
