D054 is a premium 350 GSM spacer rayon polyester fabric for autumn casual wear, engineered with a three-dimensional sandwich structure to deliver exceptional loft, structural rigidity, and warmth. As a specialized rayon polyester spacer fabric supplier, we design this material with a precise composition of 50% Polyester, 42% Rayon, and 8% Spandex to serve the mid-to-high-end cold-weather apparel market. The double-knit spacer construction utilizes polyester as a structural skeleton to maintain dimensional stability, rayon to provide a soft and silky drape, and spandex to ensure comfortable stretch and shape recovery.

Tri-Fiber Engineering: Structural Rigidity, Softness, and Stretch
D054 utilizes a balanced tri-fiber composition of 50% Polyester, 42% Rayon, and 8% Spandex, where each fiber plays a distinct role in the fabric's physical performance. The 50% Polyester content forms the structural backbone of the 3D air-chamber spacer, providing essential strength, wrinkle resistance, wear resistance, and dimensional stability. To counter the stiffness of polyester, 42% Rayon is integrated into the face and back layers, delivering a soft, silky, skin-friendly touch, high drape, and natural moisture-absorbing and breathable properties. Finally, 8% Spandex provides reliable stretch and recovery, ensuring wear comfort and retention of the garment's shape.
This formulation shares the same design family logic as our lighter D051 fabric, but D054 increases the rayon and spandex ratios alongside a doubled fabric weight to achieve a significantly more luxurious hand-feel. The 8% Spandex content provides a slightly higher stretch capacity than D051 (which contains 7% spandex), balancing the increased weight with comfortable ease of movement.

350 GSM Heavyweight Structure for Autumn and Winter Insulation
D054 is the thickest and heaviest spacer fabric in our current product catalog, specifically engineered for the cold-weather apparel market. Weighing 350G/M2, this fabric features a highly lofted 3D sandwich structure that traps air to provide excellent thermal insulation while maintaining a crisp, rigid drape. Unlike standard double-knit fabrics, this heavy spacer fabric retains its volume and three-dimensional silhouette even after repeated wear.
When compared to other articles in our product family, the progression of weight and seasonal utility is clear:
- D051 (175 GSM): Lightweight option for spring and autumn.
- D515 (250 GSM): Medium-weight option for four-seasons general wear.
- D436 (330 GSM): Heavyweight option for autumn and winter.
- D054 (350 GSM): Our heaviest, thickest spacer fabric, surpassing D436 in weight, loft, and structural density.
If you are deciding between our heavyweight options, to determine which GSM suits your specific garment structure.
160 CM Width: Standard-to-Wide Format for Enhanced Yield
D054 is produced with a physical width of 160CM, offering a practical standard-to-wide format that optimizes marker planning and cutting yield for industrial garment manufacturing. This 160CM width provides a much larger cutting area compared to our narrower heavyweight option, D436 (which measures 127 CM), and is slightly wider than the four-seasons D515 (155 CM).
While it does not offer the extreme fabric-saving margins of our ultra-wide D051 (245 CM), the 160CM width of D054 strikes an optimal balance between high nesting efficiency and ease of handling on standard spreading machines. This width allows pattern makers to lay out large garment pieces—such as winter hoods, sleeves, and wide-leg panels—with minimal fabric waste.
To calculate your marker efficiency with this width, you can to run trial cuts in your manufacturing facility.
The Mechanics of the 3D Sandwich Spacer Structure
The unique performance of D054 stems directly from its advanced spacer knitting architecture, which creates an insulating micro-climate between two layers of fabric. This fabric consists of two independent outer layers connected by a micro-spacer yarn layer, creating a resilient air-chamber "sandwich." The face and back layers are knitted with rayon and polyester to maximize skin-friendly comfort, while the internal connecting yarn holds the two layers apart to create a highly lofted air barrier.
This air pocket insulates against cold external temperatures while allowing moisture-absorbing and breathable airflow. The high concentration of polyester in the internal structure provides the physical resilience required to prevent the fabric from collapsing, ensuring the 3D silhouette remains intact throughout the garment's lifecycle.

Recommended Applications for D054 Spacer Fabric
With its combination of heavy weight, soft hand-feel, moderate stretch, and thermal insulation, D054 is engineered for premium autumn and winter casual apparel. The structured drape and loft make it highly suitable for the following garment categories:
- Autumn and Winter Hoodies & Heavy Casual Wear: The 350 GSM weight provides the necessary structure and warmth to create voluminous hoodies and structured sweatshirts that hold their shape.
- Autumn and Winter Outerwear & Jackets: The dense 3D spacer structure offers wind-resistant thickness and a crisp silhouette, making it an excellent shell fabric for casual jackets and light coats.
- Heavyweight Warm Loungewear: The high rayon content (42%) ensures a soft, silky, and skin-friendly inner surface, offering high-end comfort and warmth for premium indoor wear.
- Mid-to-High-End Autumn Casual Wear: The luxurious drape, combined with the quick-drying performance of polyester and the recovery of spandex, supports premium market positioning and higher retail pricing.

FAQ
Q1: What makes D054 different from other spacer fabrics in your collection? D054 is our heaviest and thickest spacer fabric, weighing 350G/M2. Compared to D051 (175 GSM), D515 (250 GSM), and D436 (330 GSM), D054 offers the highest loft, strongest structural rigidity, and best warmth, making it the premier choice for cold-weather outerwear and heavy casual wear.
Q2: How does the composition of D054 affect its drape and hand-feel? The composition of 42% Rayon, 50% Polyester, and 8% Spandex balances structural integrity with a premium touch. The high rayon ratio (42%) provides a soft, silky, and skin-friendly drape, while the polyester maintains the 3D air-chamber skeleton, and the spandex ensures elastic recovery.
Q3: Is the 160CM width of D054 suitable for high-yield marker layouts? Yes, the 160CM width is a standard-to-wide format that provides excellent cutting utilization. It is significantly wider than our D436 (127 CM) and slightly wider than D515 (155 CM), allowing for highly efficient pattern nesting on standard manufacturing lines.
Q4: Does this fabric offer dimensional stability during washing? Yes, the 50% Polyester content in D054 provides excellent dimensional stability and quick-drying performance, preventing the heavy 350 GSM structure from shrinking, stretching, or losing its shape after laundering.
