Virgin White Hydrophilic Composite Staple, Single-Side Hydro Low Melt Fiber for Hygiene & Medical Nonwoven

White Single Hydrophilic composite short fiber
2D*38MM
----------------------------------
Specifications can be customized

Product Overview

The 2D*38mm white single hydrophilic bicomponent low melting staple fiber addresses critical performance requirements in hygiene and medical nonwoven production. Standard non-hydrophilic composite fibers fail to deliver the fast liquid absorption and directional wicking needed for hygiene products. Conventional adhesive-bonded nonwovens carry risks of chemical residue, skin irritation and hard 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 skin-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 precision single hydrophilic surface treatment is a key functional feature. Unlike full hydrophilic treatment which can cause reverse leakage, single-side modification creates directional liquid transfer: fluid passes quickly through the hydrophilic surface into the absorbent core, while resisting back-wetting to keep the contact surface dry. This makes it highly suitable for the top sheet and acquisition layer of diapers and sanitary products.

Application Scenarios

Disposable Hygiene Products: Baby diapers, adult incontinence pads, sanitary napkins, panty liners and wet wipe substrates. Single hydrophilic performance supports fast liquid absorption and penetration, while soft thermal bonding ensures skin comfort and no lint irritation.
Medical & Health Nonwovens: Surgical dressings, wound care patches, face mask layers, medical disposable sheets and dental materials. Hygiene-grade purity and low-temperature bonding compatibility meet medical product safety and processing requirements.
Thermal Bonded Wadding & Filling: Spray-free thermal bonded cotton, garment interlining, quilt batting and furniture filling. Low-melt bonding eliminates the need for chemical adhesives, producing soft, breathable and formaldehyde-free padding products.
Filtration & Cosmetic Materials: Liquid filter media, air filter layers, cosmetic cotton pads and facial cleansing materials. Uniform fiber web structure and controlled hydrophilicity deliver consistent filtration and absorption performance.

Core Features & Benefits

Single Hydrophilic Surface Treatment, Controlled Liquid Wicking: Precision single-side hydrophilic modification creates directional liquid transfer performance: liquid penetrates quickly through the hydrophilic side and resists reverse wetting. It delivers fast absorption, uniform diffusion and good liquid retention, perfectly matching the functional requirements of hygiene products such as diapers and sanitary napkins.
Skin-Core Bicomponent Structure, Low-Temperature Thermal Bonding: The fiber adopts a classic skin-core structure: the outer polyethylene sheath melts at low temperatures to form strong, uniform bonding points, while the inner polypropylene core maintains fiber strength and structural integrity. It bonds reliably at low processing temperatures, reducing energy consumption and avoiding thermal damage to sensitive additives.
2D Fine Denier + 38MM Staple, Optimized for High-Speed Nonwovens: 2D fine denier produces soft, dense fiber webs with smooth hand feel and excellent opacity. The 38mm staple length is specially calibrated for high-speed carding, air-laid and thermal bonding lines, ensuring smooth fiber opening, uniform web formation and minimal fly waste.
Bright White Clean Appearance, Hygiene-Grade Purity: 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 the safety requirements for skin-contact and food-contact nonwoven products.
Soft & Lint-Free Bonding, Stable Forming Performance: Low-temperature fusion creates soft, flexible bonding points without hard spots or brittleness. The bonded web maintains good softness, drapability and tensile strength, with minimal fiber shedding and linting, suitable for close-to-skin hygiene and medical applications.
Consistent Batch Quality, Reliable Mass Production: Strict in-line control of denier tolerance, length uniformity, melting point and hydrophilicity ensures consistent performance batch after batch. It supports stable high-speed production with low defect rates, reducing production waste and downtime for manufacturers.

Frequently Asked Questions

Q1: What does single hydrophilic mean? How is it different from full hydrophilic?

A: Single hydrophilic means only one side of the fiber is treated with hydrophilic modification, while the other side remains relatively hydrophobic. This creates directional liquid transfer: liquid penetrates quickly from the hydrophilic side but resists reverse wetting, making it ideal for hygiene product top sheets where a dry contact surface is required.

Q2: What is the melting point? Can it be adjusted?

A: The standard melting point of the PE sheath is approximately 130°C. We can adjust the melting point and bonding strength according to your production process and product requirements, with lower and higher melting grades available.

Q3: Is this fiber safe for skin contact and baby products?

A: Yes. It is made from virgin food-grade polyolefin raw materials, produced in a clean closed system, and contains no fluorescent agents, harmful chemicals or irritating residues. It meets the safety standards for skin-contact hygiene and baby products.

Q4: What production processes is it compatible with?

A: It is compatible with carding, air-laid, through-air bonding, thermal calendering and needle punching processes. The 2D denier and 38mm staple length are optimized for high-speed nonwoven production lines for stable, efficient processing.

Q5: Can it be used to make thermal bonded wadding without glue?

A: Yes. The low-melting sheath bonds fiber to fiber when heated, forming stable, soft wadding structures without any chemical adhesives. This produces formaldehyde-free, breathable and skin-friendly padding products.

Q6: Can you customize hydrophilic level or other properties?

A: Yes. We can adjust the hydrophilic degree, melting point, denier, length and add functional properties such as antibacterial, odor resistant or flame retardant treatment to meet specific application needs.

Q7: Can we get samples for testing before bulk order?

A: Yes, samples are available for hydrophilicity evaluation, liquid absorption test, thermal bonding trial, web formation test and hand feel confirmation. Please contact us to request sample details.

Q8: What is the lead time for bulk orders?

A: Standard specifications are generally shipped within 3-7 working days for stock items. Custom specifications and functional modifications usually take 7-15 working days after deposit confirmation, depending on order quantity.
