The Origins and History of Diesel Jeans

Renzo Rosso began his denim journey at just 15 years old and went on to establish Diesel in 1978, marking the start of a new era in fashion defined by premium denim craftsmanship and boundary-pushing design.

Renzo Rosso's Vision and Brand Founding

To Renzo Rosso, denim was more than just fabric—it was a medium for self-expression. He envisioned a brand that would stand apart through distinctive style, uncompromising quality, and a bold attitude. Diesel was built on the principles of creativity, innovation, and excellence, with each pair of jeans meticulously crafted to reflect not just trends, but personality and character.

Evolution from Italian Startup to Global Fashion Icon

From its origins in Italy's Veneto region, Diesel grew into a worldwide symbol of rebellious, contemporary style. Known for its provocative advertising and designer collaborations, the brand maintained its unique identity while continuously adapting to—and often anticipating—global fashion movements. Diesel’s expansion was fueled by its ability to create versatile, fashion-forward apparel that resonated with diverse audiences across cultures.

Today, Diesel remains at the forefront of global fashion, celebrated for its originality, quality, and enduring appeal. The brand continues to evolve while staying rooted in the visionary spirit of its founder.

Where Are Diesel Jeans Manufactured?

Global Manufacturing Strategy of Diesel Jeans

Diesel employs a strategically diversified manufacturing approach, producing denim across both European and Asian facilities to leverage the unique advantages of each region. This global network allows the brand to maintain its signature quality while ensuring production efficiency and market responsiveness.

The Complete Manufacturing Process of Diesel Jeans

Diesel’s production process combines Italian creativity with advanced industrial precision. Every pair of jeans undergoes a detailed, multi-stage journey — from fabric sourcing to finishing.

Step-by-Step Diesel Jeans Production Process

1. Material Sourcing and Design

Diesel sources high-quality cotton and denim, often with recycled fibers. Design starts in Italy's Breganze headquarters, focusing on prototypes with edgy fits. Requirements: Sustainable materials like regenerated cotton from scraps.

At Newasia Garment Co.,Ltd. (INNBLAC) , we source GOTS-organic cotton and recycled fibers, matching Diesel's eco-standards for premium blends.

2. Cutting and Pattern Making

Fabric is cut precisely using automated machines to minimize waste (up to 15% offcuts recycled). Patterns ensure tailored fits with complex seams.

Our in-house CAD pattern-making system mirrors this process — enabling us to quickly develop Diesel-style fits such as slim, straight, and tapered jeans. Clients can customize pocket designs, stitching, and trims to achieve a unique signature style.

3. Sewing and Assembly

Pieces are sewn with industrial machines, incorporating reinforced stitching and hardware. Italian craftsmanship adds precision for durability.

At Newasia Garment Co.,Ltd. (INNBLAC) , we employ auto-cutting Gerber systems, and our sewing lines feature JUKI and Brother industrial machines. Each operator is trained for precision — ensuring reinforced seams, perfect topstitching, and minimal tolerance in measurements.

4. Finishing and Distressing (Art of the Fade)

Diesel's standout: Multi-stage chemical/dry finishing with resin coats, sanding, tints, and washes for aged looks. Technologies like mechanical recycling and ozone washing reduce impact.

We replicate the same artistry through eco-friendly washing processes:

• Enzyme & stone washing for natural softness

• Laser whiskering for consistent distressing

• Ozone & eco-bleach systems for sustainable fading

• Resin coating and hand-sanding for authentic texture

Our factory is equipped with  laser and ozone systems, delivering Diesel-level finishes while reducing water and chemical waste by up to 70%.

5.Trims and Embellishments

Diesel uses branded hardware — rivets, buttons, leather patches, and labels — to complete each design.

At Newasia Garment Co.,Ltd. (INNBLAC) , we offer full OEM trim customization, including embossed leather labels, laser-engraved buttons, and eco-friendly recycled hardware. Our team ensures branding consistency and premium presentation for every product.

6. Quality Control and Inspection

Rigorous tests for durability, colorfastness, and fit. Final checks ensure no defects.

Our ISO 9001 processes include tensile testing, ensuring Diesel-level consistency.

7. Packaging and Distribution

Eco-packaging and global shipping, with QR codes for transparency in some lines.
