Metallic yarn is not a single material but a engineered composite structure. Understanding the core construction is essential for Southeast Asian exporters looking to sell on Alibaba.com effectively, as different configurations serve vastly different applications and price points.
The Standard Construction: Most metallic yarn consists of an aluminum layer laminated between polyester film sheets, sealed with epoxy resin coating. This sandwich structure provides the signature metallic sheen while protecting the aluminum from oxidation and wear [2]. The aluminum foil itself is extremely thin—typically 0.00045 inches—making it lightweight yet visually striking.
Four Main Metallic Yarn Types (Lurex Classification)
| Type | Construction | Wash Temperature | Key Characteristics | Best Applications |
|---|---|---|---|---|
| C-Type | Acetate-butyrate film | 70°C | Classic metallic sheen, moderate durability | Fashion garments, decorative textiles |
| TE-Type | Heat-resistant resin coating | 145°C | High temperature resistance, industrial grade | Automotive interiors, technical textiles |
| MF-Type | Laminated aluminum foil | Variable | Maximum metallic reflectivity | Stage costumes, luxury packaging |
| MM-Type | Metallized discrete particles | Variable | Softer hand feel, flexible | Knitwear, embroidery threads |
Manufacturing Process Details: The production involves laminating aluminum foil with thermoplastic adhesive at 90-95°C, then slitting to standard widths. The industry standard width is 1/64 inch (approximately 0.4mm). Rough slitters produce 54mm pancakes for further processing, while micro slitters create 0.15-1mm tape filaments ready for weaving or embroidery applications [3].
Metallic fibres are produced by vacuum deposition of aluminum onto polyester or acetate-butyrate film, then laminated and slit to precise widths. The coating type determines wash-fastness and temperature resistance [3].
