で用いるにＦ′ｉ聞題てあった。Filters made of paper or cloth have high ventilation resistance, and in order to reduce the load on the ventilation fan motor, the filter must have a large area, which is uneconomical. Non-woven fabric filters have good performance properties such as low airflow resistance and high oil adsorption, but they lack rigidity and need to be reinforced with a wire mesh or plastic frame, making the casing flexible. Therefore, it was recommended to use it in places with open flames such as kitchens.

である。The flame-retardant composite fiber used in the present invention uses two types of polyolefins with melting points different by 20°C or more, and is of a parallel type or a sheath-core type so that the polyolefin with a low melting point continuously forms at least a part of the fiber surface. It is a composite fiber with a single fiber fineness of 3 to 200 deniers obtained by composite spinning, and a flame retardant is blended into at least one of the polyolefins used to an extent that a sufficient flame retardance can be obtained as a filter.

An example is a mixture with 5bzOt. The mixing ratio of the organic halogen compound and 5b=Os is 11.5m1 to 3:1 (weight ratio, 5btOs'k1), and the amount blended into the composite fiber is such that the filter has a predetermined degree of flame retardancy. Set.

くなり、目付後が生じるので好１しくない。If the single fiber fineness of the flame-retardant composite fiber is less than 3 denier, the rigidity of the nonwoven fabric after heat treatment will be insufficient, and the resulting filter will be easily deformed, which is not desirable. If it exceeds this, it becomes difficult to make a homogeneous web, and it is not preferable because it causes after-basis.

い。＠Other fibers to be used in combination with Mokuyoigo fibers are 20°C lower than the low melting point polyolefin used for flame-retardant composite fibers.
There are no special restrictions as long as the fiber has a melting point higher than
Specific examples include rayon, polyester fiber, polyamide fiber, polypropylene fiber, and cotton. If the amount of flame-retardant conjugate fiber in the mixture of flame-retardant conjugate fiber and these other fibers is less than 3ON%, the number of fusion points at the fiber contact points of the nonwoven fabric after heat treatment will decrease, and the resulting filter will deteriorate. This is not a good case because it is easily torn or deformed.

The filter of the present invention is obtained by heat treatment. The basis weight is 40f/
If it is less than M1, the oil mist capture rate and adsorption amount tend to be insufficient, and if it is 200y7vr"2B, the ventilation resistance becomes small, which is not desirable.The ventilation resistance is JIS
It is preferable that the air permeability is 100 c*/Ci·see or more according to the 7-Razier method of L-1096 (-general wt material test method).

ランス金設定する。As a method of heat treatment, the non-woven fabric is heated with hot air or infrared rays, and then formed into the desired shape using the heat press method.The method is to heat-form the fabric by placing it directly into a press mold on the sales floor. Although any known method can be used, the clearance of the mold is set so that the ventilation resistance does not become excessive.

等にかいても安全に使用することができる。The heat treatment temperature is selected from the range of above the melting point of the low melting point polyolefin bottom valve of the flame retardant composite fiber and below the melting point of the high melting point polyolefin acid component. By heat-treating the flame-retardant composite fiber at temperatures within this range, the high-melting point polyolefin component maintains its fiber shape, and the contact points of the fibers are fixed by the fusion of the low-melting point polyolefin component, resulting in a box-like shape. The filter can be made into a non-woven material of any shape, such as a rainbow-shaped material, and the resulting small area cloth-like material has great rigidity and air permeability. It is an excellent filter with low ventilation resistance and no deformation due to wind pressure. Furthermore, since this filter contains a large amount of flame-retardant composite fibers, the afterflame VU? It can be used for 4 seconds or less, and can be used safely even in kitchens.

が好１しくもちいられる。By laminating a synthetic resin net on the above web and heat-treating it, it can be formed into any shape and is integrated with the web's low melting point polyolefin, making it even more rigid without impairing the web's breathability. You can obtain filters for ventilation fans with improved performance. As the synthetic resin net, one made of a synthetic resin which softens but does not melt under the above heat treatment conditions and is made into a net shape by a monofilament gold knitting method or by a heat fusion method is used. In order to form the monofilament into an arbitrary shape by heat treatment, the fineness of the monofilament is preferably about 5,000 denier or less, and in order to improve the rigidity, it is preferably about 100 denier or more.
