Product Description
This 350GSM small check double knit fabric is engineered for heavy‑duty applications that demand exceptional durability, structure, and a refined aesthetic. The double knit construction – two interlocked layers of knit loops – creates a stable, non‑curl fabric with significantly higher tear strength and opacity than single knits or woven fabrics of similar weight. At 350 grams per square meter, this fabric falls into the heavy weight category, providing substantial body and shape retention for outerwear, automotive interiors, and bag panels. The small check pattern is integrated into the knit structure, not printed, so it will never fade or peel. The 94% polyester base offers excellent abrasion resistance, colorfastness, and wrinkle recovery, while the 6% spandex adds just enough two‑way or four‑way stretch (depending on orientation) to allow the fabric to conform to curved surfaces – such as car seat covers or backpack contours – without losing its tight, structured hand. For applications like heavy‑duty jackets, tool bag exteriors, car seat upholstery, and sofa covers, this 350GSM heavy duty small check double knit delivers the longevity and performance that industrial and consumer products require.

Key Advantages
Why this 350GSM heavy duty double knit outperforms standard fabrics:
Small check pattern adds visual texture without weakness – The integrated check does not fray, fade, or peel like printed patterns. It also helps hide dirt and wear on high‑use items.
350GSM heavy weight for maximum durability – At nearly twice the weight of typical apparel knits, this fabric resists punctures, tearing, and abrasion. Ideal for products that face daily abuse.
Double knit construction eliminates curl and maintains shape – Unlike single knits, this fabric lies flat, cuts cleanly, and holds its shape under load. No edge curl during sewing or use.
Low stretch (5.8% spandex) provides dimensional stability – The fabric has just enough give for contouring to curved surfaces (car seats, bag corners) but does not sag or stretch out of shape over time.
Exceptional tear strength (>110N) and tensile strength (>850N) – Certified for heavy‑duty straps, tool bags, and automotive upholstery where high stress is common.
Abrasion resistant for years of use – Martindale 80,000 cycles (Grade 4). Suitable for sofa covers, car seat centers, and workwear that see constant friction.
Easy care and colorfast – Machine washable (cold, gentle cycle). Resists fading from sunlight and cleaning agents. Optional water repellent finish available for outdoor or spill‑prone applications.
Primary heavy‑duty applications for 350GSM small check double knit:
Heavy‑duty jackets and work coats (shell or lining)
Car seat covers and automotive interior panels
Tool bags, backpacks, and duffel bag exteriors
Sofa and armchair upholstery (resists pet claws)
Office chair seat pads and armrest covers
Heavy‑duty workwear (knee pads, shoulder reinforcements)
Outdoor furniture cushions (with DWR finish)
Protective covers for equipment and machinery
Frequently Asked Questions (FAQ)
Q1: What makes “double knit” different from regular knit for heavy duty use?
Regular single knits curl at the edges, stretch easily, and have lower tear strength. Double knit consists of two interlocking layers, making it twice as thick, completely stable (no curl), and much more resistant to tearing and abrasion. For heavy‑duty bags or car seats, double knit is the preferred construction.
Q2: Is 350GSM too stiff for car seat covers?
No, it is ideal. Car seat covers need enough body to hold their shape and resist sliding, but the 5.8% spandex provides enough flexibility to fit over seat contours. Many premium aftermarket seat covers use 300‑400GSM double knit fabrics. For very tight curves (bolsters), we recommend pre‑stretching or using a thinner panel.
Q3: Does the small check pattern affect sewing or cutting?
No, but you will want to align the checks across seams for a professional look. The double knit does not fray, so edge finishing is simple. Use a universal needle size 90/14 or 100/16 for heavy weight. A walking‑foot machine is recommended to prevent layer shifting.
Q4: Can this fabric be used for outdoor applications?
Yes, with an optional durable water repellent (DWR) finish. Without DWR, the fabric will absorb water slowly (polyester is hydrophobic but not waterproof). For patio cushions or boat covers, specify the water repellent finish. UV resistance is already Grade 4, suitable for indirect sunlight.
Q5: How do I clean heavy duty items made from this fabric?
For car seat covers or bags: spot clean with mild soap and water, or machine wash on gentle cycle (cold), air dry. Do not use bleach or fabric softeners. For upholstery, professional steam cleaning is safe. The fabric resists shrinking (<1.5%) and color loss.
Q6: What is the minimum order for custom check colors?
Stock check combinations (black/charcoal, navy/grey, etc.) are available from 200 meters. For custom yarn‑dyed checks (any two Pantone colors), minimum order is 500 meters with a 15‑day lead time for lab dip.
Q7: Is a recycled polyester version available for this heavy duty fabric?
Yes. We can produce a GRS‑certified recycled polyester double knit with the same 94/6 blend, small check pattern, and 350GSM weight. Mechanical properties are within 5% of virgin material. Minimum order for recycled is 800 meters. Please specify recycled when requesting a quote.
