Polyester Staple Fiber 1.4D 38mm Virgin PET Staple Fiber for Spinning and Nonwoven Fabrics

Product Description

This product is a high-quality Virgin Polyester (PET) Staple Fiber, precision-engineered to meet the demanding requirements of both the textile spinning industry and the nonwoven fabrics industry. Manufactured from 100% virgin polyethylene terephthalate, it offers exceptional purity, consistent physical properties, and excellent processability.

Key Physical and Technical Characteristics

• Specification: 1.4 Denier (1.4D) × 38mm Cut Length – the most widely used specification globally, compatible with cotton spinning systems, nonwoven carding machines, and air-laid processes.

• Material: 100% Virgin Polyester (PET), ensuring no contamination, consistent whiteness, and reliable performance batch after batch.

• Finish: Semi-dull or bright luster available, with options for hydrophilic or hydrophobic finishes based on application needs.

• Tenacity: Regular tenacity or high tenacity options available, providing excellent strength and durability in end products.

• Elongation: Optimized elongation at break (20-40%) for balanced processing performance.

• Crimp: Uniform mechanical crimp ensures excellent cohesion and web formation during carding.

• Thermal Stability: Good heat resistance, suitable for various thermal bonding processes.

This fiber combines the durability, quick-drying, and wrinkle-resistant properties of polyester with excellent processing versatility for multiple downstream applications.

Applications

1. Spinning Industry (Ring Spinning, Open-End Rotor Spinning)

• Application: Production of 100% polyester yarns or blended yarns.

• Why 1.4D×38mm: This specification perfectly mimics the staple length and fineness of cotton, allowing seamless processing on standard cotton spinning equipment. It produces smooth, even yarns with excellent strength.

• End Products:

  • 100% Polyester Yarns: For woven and knitted fabrics used in shirts, dresses, sportswear, and home textiles.

  • Polyester/Cotton Blends (e.g., T/C 65/35, 50/50): For bed sheets, uniforms, workwear, and casual apparel, combining the comfort of cotton with the durability of polyester.

  • Polyester/Viscose Blends: For fabrics with enhanced softness and drape.

2. Nonwoven Fabrics Industry

• Application: Various nonwoven production technologies including needle-punched, spunlaced (hydroentangled), thermal bonded, and chemical bonded nonwovens.

• Why 1.4D×38mm: This fiber length and fineness are ideal for carding and web formation, ensuring uniform fiber distribution and consistent fabric properties.

• End Products:

  • Spunlace Nonwovens (Wet Wipes): For baby wipes, facial cleansing wipes, and household cleaning wipes. Hydrophilic finish options enhance absorbency.

  • Needle-Punched Nonwovens: For interlinings, automotive interior fabrics, geotextiles, and filtration media.

  • Thermal Bonded Nonwovens: For disposable hygiene products (topsheets, backsheets), medical fabrics, and packaging materials.

3. Filling and Padding Applications

• Application: As a blending component in fiberfill for various products.

• Why Polyester: Provides bulk, resilience, and support while maintaining lightweight properties.

• End Products: Mattress pads, cushion inserts, upholstery padding, and soft toy filling (often blended with hollow conjugate fibers).

4. Automotive Textiles

• Application: Nonwoven fabrics for automotive interiors.

• Why 1.4D Fiber: Fine denier allows for the production of smooth, uniform nonwoven fabrics used in headliners, door panels, and trunk liners.

5. Industrial Applications

• Application: Technical textiles requiring consistent quality and performance.

• Why Virgin PET: Ensures no contamination or variability, which is critical for industrial applications like coating substrates, electrical insulation, and roofing membranes.
