Abstract
The present utility model discloses a melt blown non-woven fabric for automobiles. The melt blown non-woven fabric comprises a superfine fiber layer and melt blown layers arranged on the two surfaces of the superfine fiber layer, each melt blown layer is a PP non-woven fabric, and fibers of the superfine fiber layer are uniformly arranged as a V shape. As the superfine fibers between the two layers of non-woven fabrics are uniformly arranged as the V shape, compared with the prior randomly arranged structure, the filling rate is high, and the acoustic absorptivity, the filling power and the uniformity are ideal.
Description
Technical field
The utility model relates to fiber matting, is specifically related to a kind of automobile-used melt spraying non-woven fabrics.
Background technology
Nonwoven product is seen everywhere in daily life; For example as diaper, sanitary napkin, rag and filtration, series products or the like; The multinomial important performance of nonwoven product need be carried out by the superfine fibre net, and the quality that melts and sprays of superfine fibre net is the difficult point place in the melt spraying non-woven fabrics processing.
A kind of melt spraying non-woven fabrics of the prior art; Mainly mix back injection HTHP air melt spraying non-woven fabrics by terylene and form, the product that obtains sees that from cross-wise direction the fiber alignment of mid portion is rambling irregular shape; Be difficult to obtain desirable bulking intensity and uniformity, packing ratio is lower.
The utility model content
It is higher that the purpose of the utility model provides a kind of packing ratio, has desirable bulking intensity and inhomogeneity automobile-used melt spraying non-woven fabrics.
The utility model solves the technical scheme that its technical problem adopted: a kind of automobile-used melt spraying non-woven fabrics comprises the superfine fibre layer and is laid in the meltblown layer on the superfine fibre layer two sides that the fiber in the described superfine fibre layer is in the shape of the letter V regularly arranged.
Wherein, described meltblown layer is the PP nonwoven fabric.
The beneficial effect of the utility model is: the superfine fibre between the two-layer nonwoven is in the shape of the letter V regularly arranged, compares existing disorderly and unsystematic structure, and packing ratio is higher, has desirable bulking intensity and uniformity.
Description of drawings
Fig. 1 is the cutaway view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
With reference to shown in Figure 1, the utility model discloses a kind of automobile-used melt spraying non-woven fabrics, comprise superfine fibre layer 2 and be laid in the meltblown layer 1 on superfine fibre layer 2 two sides; Fiber in the described superfine fibre layer 2 is in the shape of the letter V regularly arranged, and wherein, described meltblown layer 1 is the PP nonwoven fabric; Because the superfine fibre between two meltblown layers 1 is in the shape of the letter V regularly arranged; Compare existing disorderly and unsystematic structure, packing ratio is higher, has desirable acoustic absorptivity, bulking intensity and uniformity.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
Claims (2)
1. an automobile-used melt spraying non-woven fabrics comprises superfine fibre layer (2) and is laid in the meltblown layer (1) on superfine fibre layer (2) two sides, and it is characterized in that: the fiber in the described superfine fibre layer (2) is in the shape of the letter V regularly arranged.
2. melt spraying non-woven fabrics according to claim 1 is characterized in that, described meltblown layer (1) is the PP nonwoven fabric.
