1. Superior Chemical Resistance
Saran™ filament is resistant to acids and alkalis, and is insoluble in oils and most organic solvents, making it
suitable for use in applications involving exposure to chemicals. (Note that it is soluble in some solvents such
as tetrahydrofuran and cyclohexanone.)
2. Extremely Low Moisture Regain
With a moisture regain of less than 0.1%, its physical properties are almost completely unaffected by
absorbed water. This makes Saran™ fiber well-suited for use underwater, outdoors exposed to rain, and even
in demanding fields such as wastewater treatment and undersea applications.
3. Freedom from Mold, Bacteria Damage
Saran™ fiber is nearly impervious to mold, bacteria, and insects, so its properties are not degraded in highly
humid environments or mud. Saran™ fiber is often used underground and in contact with sludge.
4. High Elastic Recovery
With an elastic recovery of approximately 95% (from 3% elongation), Saran™ fiber resists wrinkling and
creasing. This enables the production of a 3-dimensional fabric using Saran™ monofilament.
5. Fast Color and Excellent Gloss
Because pigment is added before fiber spinning, Saran™ fiber displays vivid color with excellent
colorfastness, retaining its translucence and luster even with exposure to sunlight and weather. Its high
permeability to light enables use in applications where light transmission is required.
6. Flame Retardancy
Saran™ fiber is inherently self-extinguishing, making the addition of flame-retardants unnecessary. This
means consistent, uniform flame-retardant properties, free from variations which occur during flame-retardant
compounding. Saran™ fiber plays an important role in applications requiring high flame-retardant properties.

サランろ過布（サラン濾過布）/サランフィルター
【用途】
主にフィルタープレス、リーフフィルター、鍍金（メッキ）用アノード袋、ストレーナー、純水・イオン交換水製造装
置のフィルター等にサランろ過布が使用されております。
【特長】
サランろ過布は耐薬品性が非常に優れております。高濃度の酸・アルカリに対してＰＰ対比耐久性
があるといわれています。
サラン繊維自体の吸水性が0%に近いため、サランろ過布は、水切れやケーク離れが良く、取り扱い
が容易です。
また非常に高い難燃性を有しております。
サランろ過布はRoHS指令に適合しています。
【サランろ過布の組織と性能】
サランろ過布の織り方の基本組織は下図のように平織、綾織、朱子織になっております。
平織：最も緻密な構造で有孔度が小さく、分散粒子の捕集性はも
っとも良いが目詰まりしやすい。
綾織：捕集力、目詰まりの程度は平織と朱子織の間でありが、耐
摩擦性は良好で、ろ過速度も比較的大きい。
朱子織：捕集力は3種中、最低であるが、ろ過後のケーク離脱が
良好で目詰まりしにくい。
