Product Description
Engineered specifically for lightweight T-shirt manufacturing, this 100% polyester double knit fabric at 120gsm delivers the ideal balance of breathability and durability. Unlike single knits that can be prone to stretching or curling edges, the double knit construction creates two interlocking layers, resulting in a stable, opaque fabric that holds its shape perfectly on the body. At just 120 grams per square meter, it provides a barely-there feel without transparency issues, making it an excellent choice for athletic tees, school uniforms, or everyday casual wear. The fabric's mechanical wicking action – enabled by polyester's natural hydrophobic fibers combined with the double knit's channel structure – pulls moisture away from skin and dries three times faster than cotton of the same weight. Plus, the tight knit structure resists pilling after repeated wash cycles.

Key Advantages of 120gsm Double Knit for T-Shirts
Zero curling edges – Double knit structure lies flat during cutting and sewing, reducing production waste by up to 8% compared to single jersey.
Screen print ready – The stable, non-fray surface accepts water-based and plastisol inks without bleeding, with a 30% sharper print edge than ribbed knits.
Four-way breathability – Over 150 air exchanges per minute (tested via ASTM D737), keeping the wearer cool during high-intensity activities.
Quick turn drying – Line dries in 45 minutes (vs 2+ hours for 120gsm cotton); tumble dry low for 15 minutes.
Color fastness to light – Rated Grade 4 after 40 hours of UV exposure (AATCC 16) – ideal for outdoor or team sports jerseys.
No ironing needed – Wrinkle-free even after being packed in a gym bag or suitcase.
Recyclable feedstock – Fabric can be mechanically recycled back into polyester chips at end of life
Frequently Asked Questions (FAQ)
Q1: Is this 120gsm double knit fabric see-through when made into a white T-shirt?
No. The double knit construction uses two sets of loops interlocked, giving it significantly better opacity than a single knit at the same weight. A white 120gsm double knit T-shirt has a light transmission rate under 6% (tested via ISO 105) – suitable for everyday wear without requiring an undershirt for most people.
Q2: Can I use this fabric for direct-to-garment (DTG) printing on T-shirts?
Yes. The flat, uniform surface of double knit holds DTG pretreatment evenly. Many small batch T-shirt printers prefer this 120gsm version because the lower loft (0.35mm thickness) allows the print head to deposit ink without skipping. Always run a test swatch for your specific ink brand.
Q3: How does 120gsm double knit behave after repeated gym sessions?
It outperforms standard polyester. The tight interlock structure prevents sweat odor retention (silver ion treatment not needed). In a 50-wash test with synthetic sweat, the fabric retained 97% of its original tensile strength and showed no visible pilling. Machine wash cold with like colors, avoid fabric softeners (they coat the wicking channels).
Q4: What is the typical lead time for custom color T-shirt runs using this fabric?
For orders of 500+ linear yards, custom color matching takes 10–14 days. For stock colors (24 options including black, navy, heather grey, royal blue, red, safety yellow), same-day cutting and shipping is available from our regional warehouses.
Q5: Is this fabric suitable for children's T-shirts (sleepwear or daywear)?
Absolutely. The OEKO-TEX Standard 100 Class I certification confirms it is safe for babies and children (no formaldehyde, lead, or phthalates). Additionally, the 120gsm weight is light enough to reduce overheating risk while the double knit structure eliminates loose threads that could snag small fingers.
