1. Introduction

Spandex yarn for narrow fabric is a high-intensity elastic fiber specifically designed for the production of small-width woven or knitted bands, such as elastic tapes, waistbands, and ribbons. Since narrow fabrics require significant "power stretch," this yarn typically features superior tensile strength and load-bearing capacity compared to Spandex used in standard broad-woven fabrics.

The product conforms to the special requirement of narrow fabrics which provides the finished product with great openness and excellent flatness. Meet the special requirements of narrow fabric, giving the finished product a good opening and excellent flatness. With specific raw materials and technology to provide high resilience of ribbon, the product realizes the extraordinary experience of comfort and consideration.

2. Composition

The yarn is composed of Polyurethane segments with technical enhancements:

• High Molecular Density: Strengthened cross-links within the polymer chains to generate a powerful elastic force.

• Specialized Finishing: The fiber surface is treated to withstand extreme friction as it passes through the needles and reeds of high-speed needle looms.

3. Key Characteristics

• High Modulus (Power Stretch): Provides the necessary compressive force for elastic bands to maintain garment shape.

• Abrasion Resistance: Withstands continuous friction during high-speed weaving without fraying or breaking.

• Dimensional Stability: Ensures that elastic tapes maintain their width and thickness even after repeated stretching.

• Heat Resistance: Retains its physical properties during continuous dyeing processes or heat-transfer printing on elastic bands.
