How to Choose Package-Dyed Rayon Yarn for Woven & Knitted Fabrics
Selecting the right package-dyed rayon yarn is a critical decision for textile manufacturers and product developers who pursue both performance and color consistency. At Shanghai Samsun, our package-dyed viscose filament yarns are engineered to deliver superior dye uniformity, reliable processing performance, and excellent fabric aesthetics for both woven and knitted end-uses.
1. Why Package-Dyed Rayon Yarn Matters
Package-dyed yarn is dyed after spinning and winding the filament onto packages. This method gives textile makers and designers greater flexibility to choose colors late in development, while still achieving repeatable shade results when proper process controls are implemented.
Compared with conventional top-dyeing, package-dyeing allows:
- Accurate color matching to fabric palettes
- Minimal shade variation between production lots
- Controlled dye penetration for consistent surface feel
Shanghai Samsun’s package-dyed rayon yarns are ideal for mid-to-high-end apparel, fashion knitwear, tailored garments, and decorative textiles.
2. Key Technical Parameters for Yarn Selection
Below are the most important specifications to evaluate:
📌 Denier (Fineness)
Denier controls yarn thickness, look and hand:
- 50–75 d: Lightweight knits and scarves
- 75d–100d: Linings and midweight fashion fabrics
- 120d–600 d: Tailored woven apparel
📌 Twist
Twist level influences:
- Surface smoothness
- Drape behavior
- Fabric handle and luster
Lower twist preserves sheen, while moderate twist improves cohesion and reduces slippage in knitting and weaving.
📌 Color fastness & Package Dye Control
Proper package dye control ensures:
- Uniform color penetration
- Low batch-to-batch delta variation
- Excellent fastness to washing and rubbing
3. Recommended Specs at a Glance
| Application | Denier | Twist | Notes |
|---|---|---|---|
| Fashion knitwear | 100–150d | Low–Medium | Excellent drape and hand |
| Luxury linings | 75–100d | Moderate | Stable color, smooth feel |
| Tailored woven fabrics | 120–300d | Medium | Balanced strength & sheen |
| Decorative trims | 150–600d | Low–Medium | Enhanced luster |
Each specification above should be validated with mill trials to ensure process compatibility.
4. Package Dyeing: What Buyers Should Verify
When you evaluate package-dyed rayon yarn:
- Request a sample cone set in your exact color range
