ES Fiber

ES Fibers: A Key Component in Nonwoven Technologies

ES fibers, short for Ethylene-Propylene Side by Side, are a type of bicomponent fiber that was initially developed by a Japanese company. These fibers are extensively utilized in various nonwoven technologies, including Through Air Bonding (TAB) or Air-Through Bonding, to produce delicate sanitary layers such as Acquisition and Distribution Layers (ADL), as well as the top and back sheets in diapers and sanitary napkins.

Structure and Composition of ES Fibers

The unique structure of ES fibers typically involves a sheath made of polyethylene (PE) and a core made of polypropylene (PP). This configuration allows the fibers to maintain a soft exterior, thanks to the lower melting temperature of PE compared to PP, which forms the more rigid core. There are also variations of ES fibers made entirely from PP or a combination of PP and PET (polyester). When polyester is used as the core, the resulting nonwoven material exhibits increased strength and durability.

Customization and Applications

ES fibers are available in two main cut lengths: 3 to 30 mm and 25 to 90 mm. These fibers can be tailored to meet specific needs by incorporating properties such as hydrophilicity or hydrophobicity, depending on the customer’s requirements.

The ADL layer, derived from these ES fibers, stands for Acquisition and Distribution Layer. This layer is integral to hygiene products like baby diapers and feminine hygiene pads, serving to effectively disperse moisture and reduce skin irritation.

ShivaElyaf’s Role in ES Fiber Production

ShivaElyaf with its own production capacity offers high-quality ES fibers that are ideal for producing absorption and distribution layers in health products. These fibers provide excellent performance in terms of softness, absorbency, and distribution capabilities.
