Abstract
The utility model discloses a composite non-woven fabrics includes hydrophobic non-woven fabrics layer, polyvinylidene fluoride filter film layer, melt-blown non-woven fabrics layer, hydrophilic non-woven fabrics layer from outside to inside in proper order, and each layer becomes a whole through the roll-in complex. The utility model discloses the non-woven fabrics is formed by the multilayer is compound, and polyvinylidene fluoride filters the thin layer and melts the compound nonwoven cloth layer and be in the same place, has improved holistic filtration efficiency, and hydrophobic nonwoven cloth layer in surface can play the purpose of refusing water, and the hydrophilic nonwoven cloth layer of inlayer is good with skin affinity. The composite non-woven fabric can be applied to mask production.
Description
Technical Field
The utility model belongs to the technical field of the non-woven fabrics, a composite non-woven fabrics is related to.
Background
The mask is a common medical hygienic product, can be used for filtering air entering the mouth and the nose to achieve the effect of blocking harmful gas, smell, spray, virus and other substances, is generally made of non-woven fabrics serving as raw materials, the core material is melt-blown non-woven fabrics, and the quality of the melt-blown non-woven fabrics directly determines the quality of the mask. The existing melt-blown non-woven fabric has a single structure and uneven filtering efficiency, and the improvement of the filtering performance of the melt-blown non-woven fabric through the structural design is very important for the production of the mask.
Disclosure of Invention
The utility model discloses to the technical problem who exists among the prior art, provide a composite nonwoven fabric, this non-woven fabrics is formed by multilayer structure complex, and filtration efficiency is high, can be used to the gauze mask production.
In order to realize the purpose, the utility model discloses a technical scheme is:
the composite non-woven fabric sequentially comprises a hydrophobic non-woven fabric layer, a polyvinylidene fluoride filtering film layer, a melt-blown non-woven fabric layer and a hydrophilic non-woven fabric layer from outside to inside, wherein the hydrophobic non-woven fabric layer, the polyvinylidene fluoride filtering film layer, the melt-blown non-woven fabric layer and the hydrophilic non-woven fabric layer are compounded into a whole through rolling.
Preferably, the polyvinylidene fluoride filtering film layer consists of 1-2 polyvinylidene fluoride films.
Preferably, the melt-blown non-woven fabric layer is formed by overlapping 1-3 layers of melt-blown non-woven fabrics.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
the utility model discloses the non-woven fabrics is formed by the multilayer is compound, and polyvinylidene fluoride filters the thin layer and melts the compound nonwoven cloth layer and be in the same place, has improved holistic filtration efficiency, and hydrophobic nonwoven cloth layer in surface can play the purpose of refusing water, and the hydrophilic nonwoven cloth layer of inlayer is good with skin affinity. The composite non-woven fabric can be applied to mask production, other structural layers are not required to be added, and mask products meeting the standard can be produced by simply adopting the composite non-woven fabric.
