Bemliese™Features

Adding technology to natural materials
Bemliese is the only continuous cellulosic filament nonwoven sheet.

Three characteristics to realize the world's only product.

  • 1. Using 100% cotton linter as a material
  • 2. Binder-free production process by self-bonding features of the filament.
  • 3. Continuous filament nonwoven sheets made in our original production process

High liquid absorption and retention

The filament structure is designed to absorb liquid and be able to absorb and retain liquid 13-times* greater than its own weight. *SB283 data

Comparison of amount of liquid absorption

The sample is soaked in water and its weight is compared before and after soaking.
Ratio of liquid absorption = [Sample weight after soaking - Sample weight] / Sample weight

High liquid retention, one of cotton’s characteristics, is enhanced with our original technology. The reclaimed cellulose filament structure created by using cotton linter as a material provides a much higher level of liquid retention than cotton.

Nonwoven sheets are placed on an inclined table, and colored saline is poured on them to compare liquid absorption performance. (Incline angle: 45°; amount of pouring: 8 ml; pouring speed: 8 ml/5 seconds)

For Bemliese featuring quick absorption and high liquid retention, saline spreads in a complete circle, and liquid does not drip.

High level of adhesion

When Bemliese holds liquid, it gets very soft and clings tightly to the surface. When it is used for fascial sheet masks, it fits the skin perfectly along the facial contours.

Comparison test of attaching and detaching

BemlieseOther

After skin lotion is poured on the facial sheet masks, it is left on wire netting for five minutes.
When the facial sheet masks contact the skin after the five minutes left on wire netting, it can be observed how the material changes over time
(at 0 minutes and after 5 and 15 minutes) based on attaching and detaching performance.

High transparency

When Bemliese is wet, it becomes a highly transparent sheet due to liquid that has permeated the filaments.

Comparison test of transparency

BemlieseRayon/PET nonwoven sheet

After a dry sheet is placed on the paper with characters printed, water is poured onto the sheet to compare transparency.

Bemliese becomes more transparent when it contains water, and the underlying characters grow increasingly visible.

Low particle, low lint

Continuous-filament Bemliese significantly reduces lint compare to many short fibers materials. It can be used in various applications.

Adhesive cellophane tape is stuck to the nonwoven sheet and then removed.
A comparison is made with lint remaining on the tape.
There are a very few separated filaments for Bemliese, a continuous-filament nonwoven sheet.

High purity

Bemliese is made without use of adhesive agents. Self-bonding quality of filaments reduces dissolution of impurities and can be used for various solvents.

Each nonwoven sheet is soaked in water to compare dissolution of impurities.
Binder-free Bemliese shows extremely low dissolution.

Impurity extraction test (ethanol extraction)

Each nonwoven sheet is soaked in ethanol to compare dissolution of impurities.
Binder-free Bemliese shows extremely low dissolution.

Low electrostatic charge

Since liquid contained in the filaments releases static electricity into the air, the filaments are not easily charged.

Measurement of friction-charged electrostatic potential (object: PET resin)

JFriction-charged electrostatic potential is measured and compared in line with the JIS L 1094 B method
  (friction duration: 10 seconds). This shows extremely low electrostatic charge for Bemliese.

High heat resistance

Bemliese withstands temperatures up to 260℃, and is free from the softening and decomposition characteristic of synthetic fabrics.

Nonwoven sheets are placed on a hotplate at 250°C, and change in shape in 20 seconds is compared.
While other nonwoven sheets show a change in color and shape, Bemliese shows nearly no change.

Less damage caused by friction

Since the cross-section of the Bemliese filament is nearly circular compared to other filaments, it reduces friction and damage when rubbed.

Comparison is made with scratches on the surface when different nonwoven sheets are rubbed against an artificial skin similar in elasticity to human skin.
Since the filaments are smooth, Bemliese produces almost no scratches.

High biodegradability

Bemliese undergoes biodegradation naturally when it is buried in soil.
