AUTOMOTIVE UPHOLSTERY SEWING THREAD
When it comes to restoring or customising car interiors, few elements are as critical as the automotive upholstery sewing thread. Often overlooked, this unsung hero plays a vital role in both the durability and aesthetics of automotive seating, door trims, dashboards, and more. Whether you’re a professional trimmer, an upholsterer, or a passionate DIY car enthusiast, understanding the right sewing thread for automotive upholstery is essential for achieving professional-grade results.
In this guide, we’ll explore what makes automotive sewing threads unique, why quality matters, and how to choose the right thread for your next project.
What Is Automotive Upholstery Sewing Thread?
Automotive upholstery sewing thread is a specialised thread designed specifically for use in vehicle interiors. Unlike standard sewing threads, these are engineered to withstand extreme conditions – from the blistering heat of the Australian sun to the constant friction and pressure from everyday use.
These threads must deliver on several fronts:
- Strength – to hold heavy materials like vinyl, leather, and synthetic composites.
- UV resistance – to prevent fading and degradation under sunlight.
- Abrasion resistance – to endure years of wear and tear.
- Chemical resistance – to withstand cleaning agents, oils, and spills.
- Appearance – because aesthetics matter just as much as durability.
In short, the right sewing thread for automotive upholstery not only holds the interior together but also enhances the look and feel of the car.
Why the Right Thread Matters
Choosing the wrong thread can result in premature seam failure, fading, or even total structural breakdown of your upholstery. Imagine putting in hours of work to custom-stitch leather seats, only for the seams to unravel after a few months of sun exposure or heavy use. It’s frustrating—and costly.
Using a high-quality automotive upholstery sewing thread ensures:
- Long-lasting seams that won’t split or fray under stress.
- Colour retention, even under harsh UV rays.
- A professional finish that boosts the value of your vehicle.
- Peace of mind knowing your workmanship will stand the test of time.
Popular Thread Types for Automotive Upholstery
Not all threads are created equal. Let’s look at the most common types used in car interiors and what sets them apart.
1. Polyester Thread
Polyester is one of the most popular choices for automotive upholstery. It offers excellent strength, UV resistance, and colour retention. This makes it ideal for both interior and exterior automotive applications.
- Pros: Durable, colourfast, UV and abrasion-resistant.
- Cons: Slightly less heat-resistant than some alternatives.
- Best For: General automotive upholstery, especially for cloth and synthetic materials.
2. Nylon Thread
Nylon is another robust option known for its high tensile strength and elasticity. However, it’s more prone to UV degradation, so it’s typically used in shaded or interior-only applications.
- Pros: Strong, flexible, smooth stitching.
- Cons: Lower UV resistance—can degrade faster under sunlight.
- Best For: Interior seats and cushions where exposure to direct sunlight is limited.
3. PTFE (Teflon®) Thread
For premium jobs, PTFE thread is the gold standard. It’s virtually immune to UV, chemicals, mildew, and temperature extremes. It comes with a higher price tag but offers unmatched durability.
- Pros: Ultimate UV and chemical resistance, lifetime durability.
- Cons: More expensive and harder to find.
- Best For: High-end automotive restorations or luxury vehicles.
Thread Sizes and Their Importance
Thread size, usually represented by Tex or ticket numbers, plays a critical role in performance and appearance. For sewing thread for automotive upholstery, common sizes include:
- Tex 70 – Ideal for light-to-medium duty automotive applications. Suitable for cloth seats, door panels, and trim.
- Tex 90 or Tex 135 – Great for heavy-duty jobs like leather seating, convertible tops, and dashboard coverings.
- Tex 210+ – Used in commercial vehicles, trucks, or 4WDs where extra strength is needed.
Choosing the right thickness depends on the fabric you're sewing, the desired aesthetic, and the wear the seam will endure.
Colour Matching and Aesthetic Appeal
It’s not just about strength – your automotive upholstery sewing thread also contributes to the visual impact of the interior. Whether you're going for a seamless blend or a contrasting stitch, thread colour matters.
Many suppliers offer colour-matching services to help you find the perfect thread to match OEM (original equipment manufacturer) trims or custom designs. Matching thread can create a sleek, unified look, while a contrasting stitch adds flair and highlights craftsmanship.
Pro tip: Always test the thread colour under natural and artificial lighting to ensure it matches your desired tone.
Tips for Working with Automotive Upholstery Thread
Using sewing thread for automotive upholstery requires more than just threading a needle. Here are some expert tips for better results:
- Use the right needle: Heavy-duty needles like size 18 or 20 are recommended for thick upholstery materials.
- Adjust tension settings: High-tension threads may require tweaking your machine’s settings for balanced stitches.
- Invest in a strong sewing machine: Industrial-grade machines are best for handling heavy fabrics and thick threads.
- Backstitch: Always reinforce start and end points to prevent unravelling.
- Test before you stitch: Always do a sample run to check tension, stitch length, and appearance.
