Core Advantages
1. Scientific ES + EP Blending Formula, Balanced Performance & Cost Efficiency
This product is a uniform blend of classic ES (PE/PET) and EP (PE/PP) bi-component fibers, leveraging the strengths of both materials. ES fiber delivers excellent bonding strength, high temperature resistance and dimensional stability, while EP fiber brings superior bulkiness, soft cushioning and lower material cost.
2. Spun-Dyed Green Color, Permanent No Fading & Eco-Friendly
Adopting advanced mass pigmentation technology, the green colorant is evenly added into the polymer melt during the spinning stage, instead of post-dyeing treatment. The color is firmly fixed inside the fiber body, achieving washing and rubbing fastness above Grade 4.
3. Low Temperature PE Sheath Bonding, Adhesive-Free & Food-Grade Safe
Both ES and EP fibers adopt a concentric sheath-core structure with food-grade PE as the outer layer. The PE sheath melts fully and uniformly at 110-120°C to form stable physical bonding points between fibers. No chemical adhesives, glues or binders are required.
4. 3D Medium Denier + 51mm Universal Length, Wide Process Compatibility
The 3D medium denier specification perfectly balances fiber strength, bulkiness and softness. The 51mm standard cut length is universally compatible with all mainstream carding machines, air through bonding lines, needle punching machines and air laid equipment worldwide.
5. Moderate 3D Crimp, High Bulk & Uniform Web Formation
The fiber is designed with moderate three-dimensional crimp, which brings excellent inter-fiber cohesion and high fluffy bulk. After carding and web forming, the fiber web has uniform surface weight, no streak defects and good three-dimensional fluffiness.

Frequently Asked Questions
Q1: What is the composition of this ES blended EP fiber? What are the respective advantages?
A1: It is a uniform blend of ES (PE/PET sheath-core) and EP (PE/PP sheath-core) bi-component fibers. ES provides high bonding strength and dimensional stability, while EP brings better bulkiness and cost advantage. Standard ratio is 50:50, customizable.
Q2: How is the green color made? Will it fade or migrate after heating?
A2: It adopts spun-dyed / mass pigmentation technology. Color is added during melt spinning and fixed inside the fiber. Washing & rubbing fastness is ≥ Grade 4, no fading or color migration even after high temperature bonding and washing.
Q3: What is the melting point? Is chemical adhesive needed for bonding?
A3: The PE sheath melts at 110-120°C for thermal bonding. No chemical adhesive is needed at all. It forms firm physical inter-fiber bonds, eco-friendly and free of VOC residues.
Q4: Is 51mm length compatible with hot air cotton and needle punching production lines?
A4: Yes, 51mm is a standard universal length for nonwoven industry, fully compatible with carding, air through bonding, needle punching and air laid equipment, can be directly used for production.
Q5: Can I adjust the blending ratio of ES and EP? Can other colors be customized?
A5: Absolutely. We support customized ES/EP blending ratio, fiber denier, cut length and color shades according to your product performance and appearance requirements.
Q6: Does this fiber meet food contact safety standards?
A6: Yes. It uses food-grade PE raw material, free of heavy metals and harmful substances, meets FDA food contact standards and REACH regulations, safe for food packaging and hygiene products.
Q7: Can I get free samples for bonding test and color confirmation?
A7: Small test samples are provided free of charge for melting point test, bonding trial, color fastness verification and production line trial production.
