Tested and proven benefits of this unique cellulose continuous-filament nonwoven.
Natural Materials, Leading Technology.
Nature achieves perfection over centuries of evolution. Asahi Kasei complements this with proprietary technology that also is driven by a constant desire to ensure and improve quality for Bemliese™. Bemliese™’s many applications, current and those under development, rely on this dedication.
Because Bemliese™ is made from a naturally derived material, it is highly biodegradable and can be decomposed by living organisms.
Biodegradability Test
Bemliese™ (110g/m2)
Biodegradability test, by mixing nonwoven fabric with compost and incubation in a dark place at a temperature of 28℃. Water content checked regularly. Adjusted as needed. Compost regularly stirred, with visual verification of the state of decomposition of nonwoven fabric.

Degradability Test
Compared to other biodegradable nonwovens, Bemliese™ has a higher rate of biodegradability.
Test parameters
Immersion in soil in accordance with JIS K 6955.
Sample dimensions 10㎝×5㎝ (40g/㎡) buried in earth and incubated at 20～28℃, rate of decomposition confirmed.
High liquid absorption and retention
The filament structure is designed for superior liquid absorption, able to absorb and retain liquid 13 times* over its own weight. Asahi Kasei enhances the natural liquid retention capability of cotton with its own, original technology. The reclaimed cellulose filament structure created by using cotton linter as a material provides a much higher level of liquid retention than untreated cotton.

High adhesion
Bemliese™ has the ability to cling tightly to surfaces as it becomes soft from absorbing liquid. This makes it an ideal material for facial sheet masks due to its perfect fit to skin along facial contours.

High transparency
When Bemliese™ is wet, it becomes highly transparent due to the liquid that has permeated its filaments.

Low electrostatic charge
Since liquid contained in the Bemliese™ filaments releases static electricity into the air, the filaments are not easily charged.

High heat resistance
Bemliese™ withstands temperatures up to 260℃, and is free from the softening and decomposition characteristics of synthetic fabrics.

Less damage from friction
Since the cross-section of the Bemliese™ filament is nearly circular in comparison to other filaments, it reduces friction and abrasion damage when rubbed.

【Measurement Conditions】
JIS L 1076 Method C applied
Fiction applied 20 times with an appearance retention tester
Mimic skin (agar) used instead of friction plate
Base area of specimen holder : approx 13cm2
Pressing force of load : approx 3.92 N
(specimen holder, holder prop, and weight)
Bemliese filaments have a virtually circular cross-sectional structure compared to other filaments.
This reduces friction and helps to mitigate abrasive contact damage.
