D139 is a 170G/M2 single jersey nylon spandex fabric for athletic wear, featuring a weft-knitted butterfly mesh structure. Composed of 93% Nylon and 7% Spandex with a 100D + 40D yarn specification, this fabric balances structural strength, abrasion resistance, and moderate stretch. Measuring 155CM in width, D139 is optimized for activewear, sportswear linings, and breathable athletic jerseys that require high ventilation and shape retention without high compression.

93/7 Nylon-Spandex Composition for Durability and Moderate Stretch
The 93% Nylon and 7% Spandex blend of D139 is engineered to prioritize material strength, abrasion resistance, and excellent breathability over high-compression tight wrapping. While standard athletic fabrics often use 10% to 20% spandex, D139 utilizes a 7% spandex content to deliver a stable, supportive stretch that prevents the fabric from sagging or losing its shape during dynamic movements. The high 93% nylon composition ensures superior durability, rapid moisture evaporation, and a lightweight feel, making it an ideal choice for high-wear athletic apparel.
Nylon provides the primary physical properties of strength, abrasion resistance, and good elastic recovery, while the 7% spandex adds high stretch with strong elastic recovery. Instead of squeezing the wearer with high compression, this specific ratio allows the garment to drape naturally and follow body movements comfortably. This makes D139 highly suitable for athletic jerseys and performance wear where freedom of movement and structural integrity are prioritized.
Robust 100D + 40D Yarn and 170G/M2 All-Season Structure
D139 utilizes a 100D nylon ground yarn paired with a 40D spandex inlay to construct a robust, 170G/M2 medium-weight butterfly mesh fabric. Unlike lighter fabrics that use finer 40D yarn and feel overly sheer or loose, the 100D nylon yarn provides a fuller hand feel, better coverage, and a highly stable mesh structure. This 170G/M2 weight sits perfectly in the standard 130–170G/M2 range for performance wear, offering an all-season fabric solution that remains crisp, wrinkle-resistant, and highly resistant to deformation.
The combination of a 100D main yarn and a 40D elastic yarn ensures that the butterfly mesh design retains its shape even under repeated tension. With a standard width of 155CM, D139 aligns seamlessly with industrial cutting and markers, minimizing fabric waste during garment production. The 170G/M2 weight delivers the perfect balance of lightweight breathability and physical substance, ensuring garments look structured and professional.
Weft-Knit Butterfly Mesh for Ventilation and Comfort
The weft-knit single jersey construction of D139 features a specialized butterfly mesh pattern that delivers ventilation, moisture permeability, and a soft, skin-friendly feel. Weft knitting allows the fabric to stretch horizontally and conform comfortably to the body, while the unique butterfly-shaped apertures facilitate rapid air circulation to channel body heat and moisture away. This structural design prevents the fabric from clinging to the skin during intense physical activities, maintaining a dry and comfortable microclimate.
Because nylon naturally features low moisture absorption and quick-drying properties, the addition of the physical butterfly mesh holes further accelerates sweat evaporation. Additionally, this structure is highly durable and resists pilling or snagging compared to standard mesh fabrics. For brands looking to add specialized performance, D139 supports functional finishes such as UV protection (UPF), moisture-wicking, quick-dry, and anti-bacterial treatments, complete with third-party test reports.
Target Applications for D139 Fabric
D139 170G/M2 single jersey nylon spandex fabric is highly versatile, making it suitable for athletic wear, base layers, casual fashion, and functional accessories. Its balance of moderate stretch, high abrasion resistance, and excellent ventilation makes it particularly effective for garments that require durability and breathability without the heavy restriction of high-compression fabrics.

FAQ
This FAQ section provides direct answers regarding the technical specifications, performance properties, and care instructions for D139 170G/M2 single jersey nylon spandex fabric.
- Q: What is the stretch profile of D139 compared to high-spandex fabrics?
A: D139 contains 7% spandex, which provides moderate stretch and good elastic recovery rather than tight, high-compression wrapping. It is designed to offer freedom of movement and shape retention, making it perfect for loose-fitting athletic jerseys, linings, and comfortable activewear. - Q: How does the 100D yarn affect the transparency and durability of the mesh?
A: The 100D nylon yarn used in D139 is thicker than typical lightweight 40D yarns, providing a more robust hand feel, better coverage, and a highly stable mesh structure that is less sheer and highly resistant to tearing or snagging. - Q: Can D139 be customized with functional treatments?
A: Yes, the butterfly mesh structure of D139 can be treated with functional finishes including moisture-wicking, quick-dry, anti-UV (UPF), and anti-bacterial properties, backed by third-party testing reports. - Q: What are the care and handling instructions for D139?
A: Nylon-spandex fabrics have lower resistance to prolonged direct sunlight and high temperatures. We recommend washing at low temperatures, avoiding high-temperature ironing, and drying away from direct sunlight to preserve the elastic recovery of the spandex.
