What is ES Fiber?

8

ES Fiber is a bi-component thermo-bondable fiber, made of two thermo-

plastic polymers with different melting point. Difference of melting points

between the sheath component and the core component gives thermo-

bondability to the fiber.

Low melting point （PE, Co-PP etc.）

（70~30%）

High melting point （Homo-PP, PET etc.）

（30~70%）

Bonding Point 3D-Crimp Fiber

EsSoft

EsSoft is Airthrough nonwoven fabric, formed by ES fibers with hot-air

treatment without adhesive. EsSoft has excellent softness, high bulkiness

and excellent absorbency, and is also safe as it is made without adhesives.

Market Trend of Nonwovens for Hygiene Application in Asia

Japan

• Airthrough nonwoven is mainly used for topsheet and backsheet due to dryness softness, and surface smoothness.

• 3D textured topsheet became standard for premium products.

• Additional functions such as “skin friendly”, “stretchable” and “organic” are key words for differentiation.

14

Market Trend of Nonwovens for Hygiene Application in Asia

China

• Premium diapers made in Japan has been showing good sales but overall sales are slow from the second half of 2018.

• Air-through nonwoven topsheet became standard not only by the global brands but also by the local brands.

• Aperture or 3D textured nonwovens have introduced into the market and growing fast.

• The sales channel rapidly shifted from retailer to E-Commerce. It made easier for start-ups to enter the market, meanwhile this trend lowered market pricing.

ASEAN

• Air-through nonwoven topsheet is becoming mainstream.

• Products are designed to match requirement by region or country.
