Threads for Car Industry 

In the car industry, the quality and performance of every interior component directly impact both vehicle aesthetics and user safety. One often-overlooked yet critical element is the selection of threads for car upholstery and automotive interiors. Automotive sewing threads determine the durability, appearance, and reliability of sewn seams across seats, seatbelts, child seats, and decorative finishes. For OEMs, Tier 1 suppliers, and upholstery manufacturers, choosing the right high-strength sewing threads is fundamental to achieving repeatable production quality, complying with safety standards, and enhancing final product value.

Applications of Threads in Automotive Upholstery

The diversity and technical demands of automotive interiors require purpose-designed threads for each material and application. Our portfolio covers a comprehensive range of threads for car industry needs, with solutions tailored to both leather and textile upholstery, as well as for safety-critical and decorative seams.

Threads for Leather Upholstery

Leather upholstery sets unique expectations for strength, abrasion resistance, and visual consistency. For these demanding needs, we offer a selection of specialized polyester and polyamide threads:

• MARS 40, 40N, 20: Continuous polyester threads renowned for high abrasion resistance, ideal for assembly seams in premium leather upholstery. Their uniformity ensures consistent seam quality and low wear, even under intensive use.
• MARS 15, 10: Designed for decorative seams, seatbelt stitching, and child seat applications, these strong polyester threads combine high tenacity with exceptional sewability, supporting aesthetic and functional requirements.
• MARS BD 40, 40N: Bonded, glue-reinforced variants that prevent untwisting and minimize seam breakage under dynamic loads. Essential for high-stress zones and AB seam constructions.
• GABOR 60, 40: Polyamide threads engineered for the most demanding load-bearing stitches. High elasticity and tensile strength make them suitable for critical attachment points.
• ARES 20, 10, 8, 6: Heavy-duty polyamide threads dedicated to decorative topstitching. Their robust build provides pronounced visual effects and lasting integrity, even on thick leather surfaces.

Threads for Textile Upholstery

Textile seats and trim elements call for threads that balance sewability, softness, and flexibility with long-term strength. Key solutions include:

• ESTER 40, 36, 20: Polyester core-spun threads designed to provide optimal seam strength for fabric upholstery. Their construction ensures stable stitch formation and supports high-speed sewing processes.
• POLICO 40, 36, 20: Polyester-cotton threads with a cotton outer wrap, delivering a natural feel and reduced shine. Ideal for achieving seamless integration with fabric surfaces, especially in visible areas.
• AKMENA 40, 36: Core-spun threads engineered for exceptional smoothness, combining polyester strength with a fine cotton cover. This ensures minimal seam impression while maintaining durability.

Decorative and Special Application Threads

Distinctive seam lines and colored topstitches are increasingly visible in modern car interiors to emphasize brand identity and craftsmanship. For these applications:

• MARS 15, 10: Used for bold decorative stitching and functional threads in seatbelts and child restraints, offering uniform color and superior abrasion resistance.
• ARES Series: Particularly suited for eye-catching accent stitching, where seam consistency and resistance to deformation are key.

Technical and Production Benefits

Adopting high-quality automotive sewing threads delivers clear advantages on multiple manufacturing levels:

• Enhanced Production Reliability: Engineered for consistent winding, smooth delivery, and low friction, our threads minimize machine downtime and enable repeatable seam quality, even at high production speeds.
• Compliance with Stringent Automotive Standards: Tested for color fastness, light resistance, chemical exposure, and flame retardancy, threads for car industry applications help ensure interiors meet global OEM and safety requirements.
• Increased Component Lifespan: Advanced polymer construction provides lasting performance in high-stress conditions, reducing the risk of seam failure and warranty claims.
• Improved Worker Efficiency: Excellent sewability, low lint, and optimized stretching properties support stable seam creation, lower needle breakage rates, and reduce unplanned stoppages on the production line.
• Optimized Interior Appearance and Safety: Uniform thread thickness and color, along with high mechanical strength, ensure both visual harmony and robust structural performance in critical applications such as seatbelts or airbag seams.
