ると、毛羽立となつて表れる。 In recent years, nonwoven fabric filters of this kind, in which the skin layer is made of a core-sheath composite fiber nonwoven fabric in which the sheath component is made of a fiber material with a lower melting point than the core component, have gained popularity. This is because when the surface of the skin layer is heated and pressed, only the sheath component of the core-one-sheath type composite fiber is melted, which creates appropriate gaps on the surface, ensuring air permeability and water permeability, as well as making it smooth. This is because it can be formed into However, since the skin layer and the base material layer cannot be firmly bonded simply by heating and pressing, it is necessary to overlap the skin layer and the base material layer in advance and apply needle punching to join them together. Therefore, on the surface of the epidermal layer,
Some of the fibers of the base layer are exposed, and even if the surface of the skin layer is heated and pressed, the partially exposed fibers of the base layer are only laid down, and when used, It appears as fluff.

があつたのである。 Therefore, if this type of conventional non-woven fabric filter, which uses a core-sheath composite fiber non-woven fabric for the skin layer, is used for a long period of time, dust etc. will accumulate in the fuzz generated as described above. There were cases where the dust got entangled and it became impossible to easily brush it off.
本考案は、かかる実情に鑑み、表面に毛羽立が
生じることがなく、長期に亘つてダスト等の剥離

なることを特徴とするものである。 The nonwoven fabric filter of the present invention has a base material layer that includes
A nonwoven fabric made of low melting point fibers is layered on the surface of a nonwoven fabric made of arbitrary synthetic fibers and needle punched, and a core made of a fiber material whose sheath component has a lower melting point than the core component is used for the skin layer. By using a nonwoven fabric made of single sheath type composite fibers, overlapping them and heating and pressing them from the surface of the skin layer, the low melting point fiber of the base layer and the core of the single sheath type composite fiber of the skin layer are combined. It is characterized in that the base material layer and the skin layer are integrally bonded by melting the components, and the surface of the skin layer is formed to be smooth.

６よりなる。 Hereinafter, the present invention will be explained with reference to embodiments shown in the drawings. In the drawings, 1 is a base material layer;
is the epidermal layer. The base material layer 1 has, for example, a basis weight of
300g/ m2 polyester fiber spunbond non-woven fabric 3 and 250d polyester multifilament yarn for warp and weft, 27 pieces/inch each
It consists of a woven fabric 4 with a basis weight of 65 g/m 2 and a non-woven fabric web 5 of low melting point polyester fiber with a basis weight of 50 g/m 2 , and these are overlapped to form a needle with a needle density of 60 pieces/cm 2 It consists of a punched one. In addition, the skin layer 2 is a nonwoven fabric with a fabric weight of 50 g/m 2 of core-and-sheath type composite fiber using low melting point polyester fiber as its sheath component and polyester fiber with a higher melting point than the sheath component as its core component. Consisting of web 6.

cm width and high strength, and also has low elongation at break.
A product with low elongation of less than 20% was obtained. Furthermore,
According to the air permeability test according to JIS-1096, 15 to 18
It was possible to obtain an air permeability of cc/cm 2 /sec.

織布フイルターを得ることができる。 First, the nonwoven fabric filter of the present invention uses a core-sheath type composite fiber in which the sheath component is made of a fiber material with a lower melting point than the core component, so when the surface is heated and pressed, the surface becomes smooth. As a result, dust and the like can be easily peeled off. Moreover, unlike conventional non-woven filters, needle punching is not performed between the base material layer and the skin layer, so the fibers of the base material layer are not exposed on the surface of the skin layer, making it easy to use. No fluff will form even if Therefore, it is possible to obtain a nonwoven fabric filter that can easily remove dust and the like and has excellent dust collection and filtration efficiency over a long period of time.

と表皮層は、従来の不織布フイルターのように、
両者間にニードルパンチを施すことなく、強固に
結合することができるのである。 In addition, since the nonwoven fabric filter of the present invention uses a nonwoven fabric with low melting point fibers on the surface of its base layer, when it is overlapped with the skin layer and heated and pressed from the surface of the skin layer, the skin layer forms a core-sheath type. Since the low melting point fibers are melted together with the sheath component of the composite fibers, the base layer and the skin layer are similar to conventional nonwoven filters.
This allows for a strong bond between the two without needing a needle punch.

きるようになつている。 In addition, the nonwoven fabric filter of the present invention uses a nonwoven fabric made of low melting point fibers on the surface of the base material layer, but this nonwoven fabric made of low melting point fibers is needle-punched between it and the nonwoven fabric made of arbitrary synthetic fibers in the base material layer. As a result, some of the synthetic fibers become entangled within the nonwoven fabric of low melting point fibers and are exposed to the surface.
Even after the low melting point fibers are melted, air permeability etc. in the base material layer can be ensured through the optional synthetic fibers.

である。 By the way, in the above embodiment of the present invention, spunbond nonwoven fabric 4 made of polyester fiber was used as the arbitrary synthetic fiber nonwoven fabric of the base material layer. Since it has a low elongation, it can be made suitable for dust collection bag filters for smoke exhaust equipment, etc., and does not elongate due to the weight of dust. Of course, any synthetic fiber nonwoven fabric may be reinforced with a woven fabric. In particular, as in the examples, spunbond non-woven fabrics are prone to ribbing, so by reinforcing the woven fabric, ribbing can be eliminated, and in addition, non-woven fabrics with excellent high strength and low elongation can be used. It can be used as a filter.
