Colorfastness (resistance to fading) and stain resistance are critical for textiles in high-traffic environments. Solution-dyeing is the best method because the color is added to the polymer solution before the fiber is extruded, locking the color into the fiber’s core. This makes the fiber highly resistant to fading from UV light, cleaning, or wear, and it also enhances stain resistance because the color is integral, not surface-applied. Option A (yarn-dyeing) dyes the yarn before weaving, offering good colorfastness but less stain resistance. Option B (piece-dyeing) dyes the fabric after weaving, making it more prone to fading and staining. Option D (stock- or fiber-dyeing) dyes loose fibers before spinning, which is less consistent and less resistant to fading than solution-dyeing.
Verified Answer from Official Source:
The correct answer is verified using NCIDQ IDFX content on textile manufacturing and performance.
Exact Extract:TheNCIDQ IDFX Reference Manualstates, “Solution-dyeing is the best method for colorfastness and stain resistance, as the color is integrated into the fiber during manufacturing, making it highly durable.”
The NCIDQ IDFX curriculum covers textile production methods, with solution-dyeing being the preferred choice for durability and performance in commercial applications.
