    摘要： An object of the present invention is to improve a problem of the decrease in the internal tearing strength and water repellency in accordance with the decrease in the basis weight of a filter medium for air filters, and to provide a filter medium for air filters that can also address a demand for flame retardancy. The low-basis-weight filter medium for air filters according to the present invention is characterized by glass short fibers (A) and short fibers of hydrophobic chemical synthetic fibers each having a fiber diameter of 5 µm or less (B), as raw material fibers of the filter medium, by a mass ratio (A/B) in the range of from 70/30 to 95/5; a hydrophobic synthetic resin-based binder is added to the filter medium by 3 to 10 parts by mass of with respect to 100 parts by mass of the raw material fibers; and the filter medium has a basis weight of from 25 g/m 2 or more to 50 g/m 2 or less.

    摘要： A self-adhesive fiber mat may include glass and/or polymer fibers and bi-component fibers intermixed therewith. The bi-component fibers may include a core material and an outer material surrounding the core material. The outer material may have a low melting point temperature relative to the core material that may soften when exposed to heat enabling the bi-component fiber to bond with fibers and/or surfaces adjacent to the bi-component fibers. Alternatively, the self-adhesive fiber mat may use a heat sensitive resin (bonding resin) as a binder instead of, or in addition to, the bi-component fibers. The heat sensitive resin may bind the fibers together and may also bond the self-adhesive fiber mat with an adjacent film or sheet. Bonding between the film or sheet and the self-adhesive fiber mat may occur as a result of the bi-component fibers or heat sensitive resin being exposed to heat and/or pressure.

    摘要翻译： 自粘纤维毡可以包括与其混合的玻璃和/或聚合物纤维和双组分纤维。 双组分纤维可以包括芯材料和围绕芯材料的外部材料。 外部材料可以具有相对于芯材料的低熔点温度，当暴露于热量时可以软化，使得双组分纤维能够与邻近双组分纤维的纤维和/或表面结合。 或者，自粘纤维毡可以使用热敏树脂（粘合树脂）作为粘合剂，而不是双组分纤维，或者除了双组分纤维之外。 热敏树脂可以将纤维结合在一起，并且还可以将粘合纤维垫与相邻的薄膜或薄片粘合。 作为双组分纤维或热敏树脂暴露于热和/或压力的结果，可能会发生膜或片与自粘纤维垫之间的粘结。

    摘要： The invention relates to a method comprising: a step for dispersion of cut filaments and discontinuous fibres of PVOH in an aqueous process liquor, then a formation step for a bed in a formation device by passage of the dispersion over a formation cloth, through which the aqueous process liquor is drained, the filaments and fibres being retained on said cloth, then a thermal treatment step in a curing device. The PVOH fibres give a degree of resistance to the fibre bed in formation. The method provides a veil with a very high degree of tensile strength for a low level of binding agents.

    摘要： A wet-laid nonwoven reinforcing mat includes a base web containing 10 to 80 percent by weight glass fibers and 20 to 90 percent by weight polyethylene terephthalate fibers, and polyvinyl alcohol in an amount of 5 to 35 percent of the combined weight of the glass fibers and the polyethylene terephthalate fibers. The reinforcing mat also includes a secondary binder in an amount of 10 to 30 percent of the total weight of the base web.
