OUR TECHNOLOGY ECOPET® Technology
Although it is recycled polyester, ECOPET® is not only environmentally-friendly but also has many functionalities and sensitivities added by changing fiber shapes and thicknesses or by processing. The advancement of fiber technology has enabled ECOPET® not only to deliver new value, such as recycling and environmental friendliness, but also to continue evolving as a material that makes people’s daily lives better.
Functionalities added by fiber shapes
SHAPE
case01
- Outline
- This new functional polyester has a unique cross-sectional shape comprised of four flat mountains.
- Functions
- Features multi-functionality, including softness and draping, sweat absorption, quick-dry, anti-see-through, and windbreak functions.
- Grooves created on the fiber surface by four mountains → Sweat-absorption and quick-dry functions achieved by capillary action
- Irregularities created on the fiber surface by four mountains → Anti-see-through function achieved by the scattering of passing light
- Low bending rigidity due to the flat cross-sectional shape → Soft and draping function
case02
- Outline
- Polyester fiber with a new feel, featuring high sweat absorption, quick-dry, dry-touch, and lightweight functions
- Functions
-
- Water absorption and drying characteristics: Twice as high as those of conventional products, making it a non-sticky, dry-touch material
- Wash durability in terms of sweat absorption: More than twice that of conventional products
- Lightweight
case03
- Outline
-
- By leveraging our unique technology to create yarn with odd cross-sectional shapes, we arranged eight protruding objects radially on a hollow fiber to let the gaps between fibers created by the eight protruding objects provide different functions.
- Potential for broader use that can be achieved by combining it with other materials via false twisting, combination of different filaments, or twisted yarn spinning
- Functions
- Sweat absorption, quick dry, lightweight, heat shield, heat insulation, and dry touch
case04
- Outline
- Light, warm, thermal polyester fiber that can contain lots of dead air due to its hollow structure
- Functions
-
- Rate of hollowness: 35% to 40%
- So light it floats on water
- High elasticity and firmness
Functionality and sensitivity achieved
by the thinness of the fibers
THINNESS
case01
- Outline
-
- Special polymer and microfiber of 0.3 dtex (single yarn) created via ultrafine fiber yarn-making technology
- Directly spun yarn that is different from split fibers or super thin yarn of the Kaito type
- Tender feel achieved by ultrafine fibers
case02
- Outline
-
- The surface area of textiles made of nanofibers is dozens of times larger than that of conventional fibers.
- Compared to conventional fibers, it has higher water absorption and adsorption performance and a higher anti see-through property.
- The texture of the textile is soft, causing little skin irritation.
- It has a wide range of uses, such as functional sportswear, innerwear, skin-care products, antibacterial filters, and precision polishing cloths.
Characteristics obtained by pasting fibers together
PASTE
case01
- Outline
- Highly crimped fiber, natural appearance, stretch textile, low luster hybrid worsted-type material
- Characteristics
-
- Features a feel with a wool-like fluffiness, spun-touch, resilience, elasticity, and firmness.
- Wool-like natural appearance, low luster appearance, and appearance with profound colors
- Products that have stretch and anti-wrinkle properties, that look nice when tailored, and that are easy to care for
Functionalities achieved by processing
PROCESS
case01
- Outline
-
- Highly water-resistant, moisture permeable material created by using ECOPET®
- 100% waterproof and moister permeable polyester films are used.
- Both comfort and environmental friendliness are achieved without making any compromises.
- The base cloth is made of highly water-repellent microfiber fabric.
case02
- Outline
- Vertical nonwoven fabrics that have fibers lined up vertically can become a high-quality fiber cushioning material featuring high repellence, bulkiness, lightweight, and high breathability by combining them with high-performance Raw staple fiber. Moreover, they are easy to bend and mold. Sound absorption can be controlled by combining them with a surface material or via pressing.
