熔喷线:由微纤维生产无纺布。


它们的直径比人的头发小七倍。熔喷织物的微纤维非常适合用于过滤,用作复合产品中的抹布或阻隔层。无论您希望生产什么:我们提供正确的技术。



熔喷布具有很好的吸收性,弹性或极高的过滤和阻隔性能。使用熔喷单排和多排技术,您将始终能够生产出适合您应用的正确的熔喷无纺布。


RF4 / RF5单排
熔喷技术

最佳阻隔和过滤性能。

在REICOFIL单排熔喷工艺中,聚合物是通过喷丝嘴纺出的,该喷丝嘴在单排中设有数百个孔。在喷丝头尖端两侧流出的热空气流会使聚合物熔体变细,形成最细的长丝,随后被高速空气吹到收集器筛网上。结果是具有优异的阻隔和过滤性能的熔喷织

产品特性
纤维直径小于1µ

通过单行熔喷工艺生产的连续纤维的直径小于一微米。这使其适合于生产具有H12过滤效率的高要求HEPA过滤器。

产品质量
定向送风

在REICOFIL单排熔喷工艺中,所有细丝都在完全相同的温度下在整个模具宽度上拉伸。均匀的拉伸可在整个材料纤维网上保持恒定的纤维质量。

工艺稳定性
单件式模具可达5.2m

焊缝可能会导致非织造布出现瑕疵。因此,我们始终将熔体分布在单片模具上,即使线宽为5.2米也是如此。您的好处:熔体分布均匀,只有一个旋转泵,只有一个喷丝板。


独立熔喷生产线
(具有单行和/或多行技术)


结合单排和多排技术
创新的可互换卡带

一条线同时使用两种技术。我们的可互换盒式模具允许您在单排和多排技术之间进行转换,这可与标准换模头相比,可以改装为所有熔喷线。

  • Meltblown lines

    Production of nonwovens from microfibres.

  • They are seven times smaller in diameter than a human hair. The microfibres of a meltblown fabric are perfectly suited for use in filtration, as wipes or as barrier layers in composite products. Whatever you wish to produce: We supply the right technology.

    Two technologies
    Meltblown production without compromises.

    Absorbent, elastic, or very high filtration and barrier properties? We offer technologies for all properties. With our REICOFIL® meltblown singlerow and multirow technology you will always be able to produce the right meltblown fabric for your application.

    RF4 / RF5 Singlerow
    meltblown technology 

    Optimum barrier and filtration properties.

    In the REICOFIL singlerow meltblown process, polymer is spun through a spinneret provided with hundreds of holes in a single row. Streams of hot air exiting at both sides of the spinneret tip attenuate the polymer melt to form the finest filaments which subsequently get blown by high velocity air onto a collector screen. The result is a meltblown fabric with excellent barrier and filtration properties.

    Product properties
    Fibre diameter under 1µ

    The continuous fibres produced by the singlerow meltblown process have a diameter below one micrometer. This makes them suitable for the production of highly demanding HEPA filters with H12 filtration efficiency.

    Product quality
    Targeted blowing of secondary air

    In the REICOFIL singlerow meltblown process all filaments are stretched across the whole die width at exactly the same temperature. The uniform stretching results in a constant fibre quality over the entire material web.

    Process stability
    Single-piece die up to 5.2m

    Weld seams can lead to flaws in the nonwoven fabric For ths reason, we always distribute the melt across a single-piece die – even at line widths of 5.2 meters. Your benefits: even melt distribution, only one spin pump, and only one spinneret.

    Combining REICOFIL singlerow and multirow technologies
    The innovative interchangeable cassette

    Use both technologies in one line. Our interchangeable cassette allows you to change between REICOFIL singlerow and multirow technology, which is comparable with a standard die change. The cassette can be retrofitted to all REICOFIL meltblown lines.

    Meltblown
    Properties and raw materials.

    Physical properties

    lf-bonding / thermo bonded

    • large areas / weight ratio
    • adjustable structure of pores and capillaries
    • hydrophobic / oleophilic (PP meltblown)
    • Excellent wick effect / liquid absorption capability
