NANOFRONT®
Features
World’s first ultra-fine polyester nanofiber.
NANOFRONT® is the world’s first ultra-fine polyester nanofiber. With a diameter of merely 700 nanometers, one fiber is 1/7500 of a human hair.
The surface density of fabric made with NANOFRONT® is about 10 times greater than other fabrics. And since the undulations are at nano-level, the fiber surface produces a large frictional force for strong gripping power. The perfect fit makes the fiber suitable for gloves, innerwear, supporters, etc.
Biomimetics technology
The surface structure of the NANOFRONT® mimics the structures of Japanese gecko and leaf beetle’s legs.
On the top of that, the frictional resistance increases when it gets wet from sweat or rain.
TEIJIN’S NANO FIBER-Nanofront
Teijin invented stable quality of world’s first 700 nanometer ultra-fine polyester nanofiber by using its unique ‘New Sea/Island Separatable Fiber Technology’. It was commercialized in 2008.

POSSIBILITY OF -Nanofront
Basically all melt-type polymers can be processed into Nano fiber. On top of PET, Ny, PP are available now.
- The surface area of -Nanofront woven in filaments structure could be tens of times greater than conventional fibers.
- This enhances water absorption, slip resistance,and opaqueness.
- The texture feels soft to the skin, and irritation is reduced dramatically.
- Suitable for a variety of applications, including functional sportswear, innerwear, skin care products, antibacterial filters, precision grinding cloth, etc.
Filter Products
Nanofront application was expanded into filtration fields.

PET Nanofront, (in near future PPS as well)
02Liquid cartlidge filter :

STRUCTURE OF Nanofront FELT
Nanofront felt is composed of 2 layers, Unique Nano fiber Sheet and Base felt.
1. Nanofront Sheet
- By dispersing even diameter of Nano fibers, achieves high dust collecting efficiency.
- By dispersing thicker diameter of fibers, it makes possible to keep even porous and high air permeability (low pressure loss) → SAVE ENERGY
- High dust collecting efficiency can prolong time to clogging → LONGER LIFE
2. Base felt
2: Base felt
TEST EQUIPMENT OF FILTRATION EFFICIENCY
In order to assure our assumption, we implemented test to analize filtration efficiency.
- JIS Z 8909-1
- Test items:shifting of pressure loss, pulse interval, amount & ration of dust emission
TEST RESULT VS. CONVENTIONL NON-WOVEN FELT
TEST RESULT VS. PTFE MENBRANE FELT AND ASSUMED REASON
Test result in labo
[A] Initial pressure loss, successive residual pressure loss
Nanofront Felt < PTFE membrane
Analysis
[B] Dust collecting efficiency
Nanofront Felt ≒ PTFE membrane
Assumed reason of the result
[A] Surface of Nanofront Felt is composed of fiber. Therefore there is no film-like area 1 and porous is not so microscopic as compared with PTFE membrane. 2
[B] Because Nanofront Sheet is fiber layer, it is not so thin as compared with PTFE membrane 3 therefore no hole which sometimes appears in PTFE membrane. 4
Liquid Filter
Nanofront LIQUID CARTLIDGE FILTER [1]
One of other applications of Nanofront filters is Liquid Cartlidge filter. On top of 700nm, 400nm＆200nm (newly developped) are being used.
Feature
As compared with conventional non-woven like meltblow, Nanofront sheet is
- 1.porous is smaller
- 2.porous distribution is sharp
- 3.extremely thin
→ Accuracy of filtration is high and filtration area is wide.
Area to Cover
Nanofront liquid cartridge filter is suitable for non-woven pleated type and part of membrane pleated type.
Nanofront LIQUID CARTLIDGE FILTER [2]
Feature
Nanofront sheet
- By dispersing even diameter of Nano fibers, achieves high dust collecting efficiency.
- By dispersing thicker diameter of fibers, it makes possible to keep even porous and high air permeability (low pressure loss)
LINE-UP
Average porus is between 0.5~5μm. It is suitable to filter particles between sub μm~5μm. And as material line-up is PET, NY and PP, choice of suitable one can be possible considering fluid compatibility.
| Polymer | Average porous |
|---|---|
| PET | 5μm,3μm,1μm,0.5μm |
| Ny | 1μm,0.5μm |
| PP | 5μm,3μm,1μm,0.5μm |
Use & Function
Shoe Lace
It’s really bothering to get shoelaces tied many times during work-out.
Here is your solution. NANOFRONT® slip-resistance shoelace prevents the shoelace from getting loose.
Socks
The structure of NANOFRONT® fabric is similar to the bottom of Gecko feet which have the amazing power to grab the objects.
NANOFRONT® fabrics which maintain constant grip are used in sports socks to maximize your performance
All Weather Glove
The surface area of NANOFRONT® is 10 times greater than that of conventional textiles the high friction propetties that characterize NANOFRONT® generate outstanding gripping force.
And surprisingly, the frictional resistance increases when it gets wet from sweat or rain.
Lingerie / Sports Inner
The undulations on the fabric surface are at the NANO-level, the fabric produces a large frictional force for super slip-resistance.
Gentle touch and outstanding fit on the skin that doesn’t restrict active motion
