Premium Yarn Quality: 40S Combed Compact Cotton
The exceptional performance of D506 single jersey fabric for casual knitwear stems from its premium yarn selection. We utilize 40S combed cotton paired with a compact spinning process, which represents a significant investment in raw material quality. The combing process meticulously removes short fibers and impurities, while compact spinning tightly binds the hairiness of the yarn. The combination of these two advanced processes results in an ultra-clean fabric surface with a delicate hand feel that is exceptionally soft against the skin without irritation. This premium yarn configuration ensures that D506 delivers superior anti-pilling performance compared to standard carded cotton fabrics, setting a new benchmark for high-end cotton spandex single jersey fabric.
Balanced Elasticity with 30D Fine Denier Spandex

To achieve the perfect balance of flexibility and structure, D506 incorporates 6% Spandex using a 30D fine denier specification. This fine denier spandex provides high stretch with strong elastic recovery, ensuring the fabric stretches easily and recovers its shape gently without feeling tight or restrictive. Garments made from this 180 gsm cotton spandex single jersey fabric offer a comfortable, body-hugging fit that allows for natural freedom of movement while reliably maintaining the garment's original shape over time. This makes it highly suitable for close-fitting apparel designs that require a snug fit without intense compression or shaping.
Optimal 180G/M2 Weight and 160CM Width for Production
With a weight of 180G/M2, D506 is a medium-to-thick single jersey fabric for casual knitwear, providing more substance and weight than conventional lightweight jersey materials. This optimal thickness significantly reduces the risk of transparency, making it a highly reliable choice for light-colored or white close-fitting garments. Brands can design white or pastel apparel with complete confidence, knowing the fabric offers excellent opacity. Additionally, the 160CM width provides excellent cutting efficiency during garment manufacturing, minimizing fabric waste and optimizing production yields.
Textured Single Jacquard Pattern with Lasting Durability

The design highlight of D506 is its sophisticated single jacquard structure. The delicate white stripes are integrated directly into the fabric using a specialized loop knitting technique. This raised, three-dimensional texture is knitted directly into the fabric structure rather than printed on the surface. Consequently, the pattern is highly durable: it is fully wash-resistant, fade-resistant, and will not peel or wear off over time. Both the face and the reverse side of the fabric maintain consistent color and texture, offering a true knitted-in design that elevates the visual and tactile appeal of the finished garment.
Recommended Applications for D506 Fabric

FAQ
What makes the yarn quality of D506 different from standard cotton spandex fabrics?
D506 uses 40S combed compact cotton yarn. The combing process removes short fibers and impurities, while the compact spinning process minimizes surface hairiness. This results in a much smoother, cleaner fabric surface that is softer to the touch and offers significantly better anti-pilling performance than standard carded cotton fabrics.

Is the white stripe pattern printed on the fabric?
No, the fine white stripe pattern on D506 is knitted using a loop jacquard structure. Because the raised texture is woven directly into the fabric rather than printed, it will not fade, peel, or wash out, ensuring the design remains intact and consistent on both sides.
Is the light-colored or white D506 fabric see-through?
With a weight of 180G/M2, D506 is slightly thicker and more substantial than standard lightweight jersey fabrics. This medium-to-thick weight reduces the risk of transparency, making it dependable for light colors and white close-fitting garments.
What is the elasticity profile of this fabric?
D506 contains 6% Spandex of a 30D fine denier specification. This provides high stretch with strong elastic recovery, offering a gentle, comfortable stretch that holds its shape well without feeling tight or rigid.
