Multi Hydrophilic composite short fiber for Can absorb water multiple times and can be used as the absorbent layer of sanitary products or diapers

Multi Hydrophilic Composite Short Fiber is engineered to absorb water repeatedly, making it an ideal choice for the absorbent layer of sanitary products and diapers.

Specification: 2D × 38 mm

Customization: Specifications can be tailored to your requirements.

The 2D × 38 mm full hydrophilic bicomponent low-melting staple fiber addresses critical performance requirements in absorbent nonwoven production. Single-hydrophilic fibers are designed for directional liquid transfer in top sheets, but cannot deliver the fast, uniform, high-volume absorption needed for absorbent cores and wipe products. Conventional adhesive-bonded nonwovens carry risks of chemical residue, skin irritation, and stiff hand feel. High-speed production lines also demand strict consistency in fiber specification and bonding performance to minimize downtime and waste.

This product is purpose-built to solve these challenges. Its sheath-core bicomponent architecture integrates bonding function and structural strength into one fiber. The outer PE sheath melts evenly under low heat to form continuous, soft bonding points across the fiber web, while the inner PP core maintains dimensional stability and tensile strength. This eliminates the need for chemical binders, producing formaldehyde-free, skin-friendly nonwoven products.

The full double-sided hydrophilic surface treatment is a key functional feature. Unlike single hydrophilic treatment which creates directional flow, full hydrophilic modification ensures rapid wetting and uniform liquid diffusion across the entire fiber web. This maximizes absorption speed, liquid retention, and absorbent core utilization, making it highly suitable for the absorbent core layer of diapers and sanitary products, as well as for wet wipes that require uniform liquid saturation.

At 2D fine denier and 38 mm staple length, it is optimized for modern high-speed nonwoven production lines. It opens and cards smoothly, forms uniform, defect-free fiber webs, and bonds consistently across the entire web width at controlled temperatures. The bright, clean white appearance provides an excellent base for hygiene and medical products that require a clean, premium visual impression.

Manufactured under ISO quality management in a closed production system, every batch is tested for denier, length, melting point, hydrophilicity, and whiteness to ensure uniform performance. We supply in bulk with stable stock and support customization of melting point, hydrophilic level, denier, length, and functional modifications such as antibacterial treatment. Samples are available for hydrophilicity testing, absorption measurement, bonding trials, and web formation evaluation before placing bulk orders.

• Double-Sided Full Hydrophilic Treatment — Fast Absorption & Uniform Diffusion Uniform hydrophilic modification across the entire fiber surface delivers instant liquid wetting, rapid penetration, and even horizontal diffusion. It provides high liquid retention capacity and consistent absorbency, making it ideal for absorbent cores, wet wipes, and filtration media where thorough, fast liquid uptake is required.
• Sheath-Core Bicomponent Structure — Low-Temperature Thermal Bonding Classic sheath-core architecture: the outer PE sheath melts at low temperatures to form strong, uniform bonding points, while the inner PP core maintains fiber strength and structural integrity. It enables adhesive-free thermal bonding, producing formaldehyde-free, skin-friendly nonwoven products with a soft hand feel.
• 2D Fine Denier + 38 mm Staple — Optimized for High-Speed Production 2D fine denier creates dense, soft fiber webs with a smooth surface and excellent absorbency uniformity. The 38 mm staple length is calibrated for high-speed carding, air-laid, and through-air bonding lines, ensuring smooth fiber opening, uniform web formation, and minimal fly waste.
• Hygiene-Grade Bright White — Pure & Non-Irritating Produced from virgin food-grade polyolefin raw materials in a closed clean production system, it features a bright, consistent white shade with no impurities, no fluorescent agents, and no odor. It meets safety standards for skin-contact, baby care, and medical nonwoven products.
• Soft Bonded & Low Linting — Stable Web Integrity Low-temperature fusion creates flexible, resilient bonding points without hard spots or brittleness. The bonded web maintains good softness, tensile strength, and dimensional stability, with minimal fiber shedding and linting, suitable for wiping and absorbent hygiene applications.
• Consistent Batch Quality — Customizable Performance Strict in-line control of denier tolerance, length uniformity, melting point, and hydrophilicity ensures consistent performance batch after batch. Hydrophilic level, melting point, denier, length, and functional modifications such as antibacterial treatment can be customized to match specific application needs.
