Polyester Stretch Knit Fabric 145GSM

,

Breathable Single Jersey Fabric

Product Description
Product Overview
This 145GSM 100% polyester single jersey fabric combines an exceptionally soft hand feel with high breathability and mechanical stretch—all without elastane or spandex. The lightweight 145GSM construction makes it one of the finest single jersey options for next‑to‑skin comfort, yet the knit loop geometry provides natural mechanical recovery that stretches with body movement and returns to shape. Unlike typical lightweight polyester fabrics that feel plasticky or clingy, this version uses fine denier filament yarns to achieve a buttery, cotton‑like touch. The open single jersey structure allows continuous airflow, preventing heat buildup during high‑intensity activities. Mechanical stretch derived from the loop architecture eliminates the need for spandex, meaning no elastic fatigue, no chlorine yellowing, and no heat degradation after repeated washing. This fabric is engineered for premium activewear, yoga tops, base layers, and lightweight team uniforms where softness, breathability, and natural stretch are non‑negotiable.

Key Advantages & Proven Applications (Bullet Points)

Why this 145GSM soft touch mechanical stretch single jersey outperforms traditional lightweight knits

  • Buttery soft without chemical softeners – The 75D/72F fine filament yarn creates a naturally smooth, draping hand feel that resists pilling. Many customers compare it to a high‑end bamboo or modal blend, but with polyester’s moisture management.
  • 145GSM ultra‑lightweight breathability – At 145GSM, the fabric weighs approximately 4.2 ounces per square yard. Ideal for summer sportswear, indoor training, and layered base garments. The open single jersey structure delivers 250+ mm/s air flow, keeping athletes cool during peak sweat.
  • Mechanical stretch for unrestricted movement – The loop geometry provides 70‑75% stretch in the weft (width) direction. No spandex means the fabric snaps back without sagging, even after hundreds of stretches. Perfect for yoga forward folds, golf swings, and high‑kick routines.
  • Prints vibrantly and holds ink – The tight, uniform loop surface accepts dye sublimation and screen printing exceptionally well. 145GSM is light enough to avoid ink pooling but heavy enough to prevent show‑through on light colors. 
  • Proven applications for soft‑touch lightweight sportswear – Currently used in: premium yoga tank tops, Pilates long sleeves, running singlet race shirts, indoor soccer jerseys, dance competition leotards, and breathable base layers for cycling.

 

 

Frequently Asked Questions

Q1: How can a 145GSM fabric be “soft touch” and still durable? Isn’t lightweight polyester usually rough?
A: Standard lightweight polyester often uses coarser yarns (like 150D/48F) to save cost, which feel scratchy. This 145GSM fabric uses 75D/72F fine filament yarns—72 individual microfibers per yarn bundle. The higher filament count creates a larger surface area that feels smooth and silky. Additionally, the single jersey loop geometry reduces friction against skin. Durability is maintained through tight loop formation and polyester’s inherent tensile strength.

Q2: What sportswear applications work best with 145GSM and mechanical stretch?
A: 145GSM is optimized for next‑to‑skin lightweight garments where breathability and softness are critical. Best applications include: yoga and Pilates tops (stretch accommodates deep bends), running singlets (lightweight and moisture wicking), indoor soccer/futsal jerseys (breathable for courts), dance and cheerleading shells (mechanical stretch follows extreme moves), and base layers for skiing or cycling (worn under outer shells without bulk).

Q3: Does mechanical stretch mean the fabric will become loose after wearing?
A: No. Mechanical stretch is derived from the knit loop geometry, not from elastic fibers. When you stretch the fabric, the loops temporarily elongate but their inherent polyester memory pulls them back to the original shape. Unlike spandex, which loses recovery after 50‑80 washes due to oxidation and chlorine, mechanical stretch remains consistent for over 100 washes. However, we recommend avoiding heat over 60°C during drying to preserve loop geometry.

Q4: Is this 145GSM soft touch single jersey suitable for sublimation printing?
A: Absolutely. The 100% polyester composition and white base (available) are ideal for dye sublimation. The 145GSM weight provides enough fiber density to hold vibrant colors without bleeding through, yet light enough to keep the garment airy. Many custom sportswear brands use this exact fabric for lightweight race shirts and yoga tops. Screen printing also works well, though we recommend low‑bleed inks for dark colors.

Q5: How breathable is “breathable” exactly? Can you provide a comparison?
*A: Air permeability measured at ≥250 mm/s under ASTM D737. For reference: a typical 180GSM cotton jersey is around 80‑120 mm/s. A 150GSM standard polyester sport mesh may reach 300‑400 mm/s but lacks softness and opacity. This 145GSM fabric balances 250 mm/s breathability with full opacity (no see‑through) and a soft touch. It allows sweat vapor to escape quickly while preventing the “wet T‑shirt cling” effect.

Q6: Can I get this fabric in recycled polyester or custom colors?
A: Yes. The standard version uses virgin polyester with OEKO‑TEX 100 certification. We also supply an equivalent 145GSM soft touch single jersey made from GRS‑certified recycled polyester (minimum order 1000 kg for recycled). Custom colors are available via Pantone matching (MOQ 500 kg per color). Black, white, ash grey, and navy are kept in stock for immediate sampling.
