In modern textile manufacturing, yarn is no longer just a supporting material hidden inside garments. It is increasingly becoming a decisive factor in product durability, sustainability, technical performance, and supply chain transparency.
As global fashion and textile industries face growing pressure from consumers, regulators, and sustainability targets, manufacturers are being forced to rethink how materials are engineered, processed, and integrated across the supply chain. From recycled polyester and organic fibers to advanced chemical management systems and performance-driven thread technologies, innovation at the yarn level is now playing a far more strategic role in shaping the future of textile production.
At the same time, rising expectations around circularity, traceability, and long-term product quality are pushing suppliers to move beyond conventional manufacturing approaches. What was once viewed as a basic commodity is now emerging as a highly engineered component capable of influencing both product performance and environmental impact.
Italian yarn manufacturer MIC Spa is among the companies positioning itself within this evolving landscape. During Techtextil 2026 in Frankfurt, the company highlighted its focus on engineered yarn solutions designed to address modern industry demands for consistency, durability, sustainability, and technical precision.
Speaking with Fashion Business Journal (FBJ), Nicola Carletti, Marketing & Product Manager at MIC Spa, shared insights into why sewing threads and yarns should no longer be treated as overlooked accessories, how environmental responsibility is reshaping yarn development, and what major transformations are expected across the global textile supply chain in the coming years.
FBJ: Yarn is often an overlooked component in textile production. How does it influence overall product performance and durability?
Nicola Carletti: Yarn may appear to be a small component, but it plays a fundamental role in the overall quality, durability, and appearance of a garment or textile product. The right yarn must align not only with the fabric type, but also with the intended performance of the final application.
When working with delicate silk fabrics, manufacturers require extremely fine and soft yarns combined with appropriate needles to avoid damaging the fabric structure. In contrast, leather applications demand highly twisted, high-strength sewing threads capable of handling significantly greater stress and resistance.
The yarn must also visually complement the material it is sewn into. If a leather surface has either a matte or glossy finish, the thread should align with that appearance; otherwise, the seam may look visually inconsistent. A seam is not only functional — it is also an important aesthetic element.
From a technical perspective, yarn directly influences abrasion resistance, breakage resistance, color fastness, softness, surface quality, and long-term durability. In many cases, the performance of the yarn determines whether a garment can maintain its integrity throughout its lifecycle.
Material compatibility is becoming increasingly important as well. Synthetic fabrics generally perform better with synthetic sewing threads, while natural materials often benefit from threads made from similar natural fibers. This helps ensure greater consistency in durability, recyclability, and biodegradability at the product’s end of life.
FBJ: What are some common misconceptions brands or manufacturers have when selecting yarns or threads?
Nicola Carletti: One of the biggest misconceptions is that sewing thread is simply a commodity. Many brands place significant focus on fabrics, trims, and accessories while underestimating the technological sophistication involved in yarn manufacturing.
A cone or bobbin of yarn is a highly engineered product. Beyond color and raw material selection, there are numerous technical considerations including resistance to chemicals, heat, flame, abrasion, UV exposure, chlorine, saltwater, and breakage.
Different applications require entirely different performance characteristics. A thread designed for swimwear must maintain color consistency and strength in saltwater environments, while a thread intended for mountain outerwear requires UV resistance and durability under extreme environmental conditions.
Technical factors such as yarn winding, lubrication, and machine compatibility are also frequently overlooked. If yarn is wound too tightly, it may not unwind correctly during sewing. If it is wound too loosely, it can slip during transportation or production. Lubrication levels must also be carefully calibrated depending on whether the yarn is intended for knitting, weaving, or sewing applications.
In lightweight fashion garments, threads are often visually invisible because they blend seamlessly with the fabric in tone-on-tone applications. As a result, many designers and product developers underestimate their contribution to both product quality and manufacturing efficiency.
FBJ: What key challenges is the yarn manufacturing sector currently facing on a global scale?
Nicola Carletti: The sector is currently facing major challenges related to environmental compliance, chemical management, raw material transition, and supply chain accountability.
MIC Spa began a significant transformation process in 2019 by implementing stricter chemical management systems across its operations and global supply network. The company collaborated with external specialists to improve chemical traceability and strengthen compliance with international industry standards.
Today, the company operates in alignment with internationally recognized frameworks including ZDHC 3.0, OEKO-TEX Standard 100 Class I, GRS, and GOTS.

Transitioning to recycled polyester was not as straightforward as simply replacing one raw material with another. Recycled polyester behaves differently during dyeing because its base tone is often slightly grey rather than pure white. This requires manufacturers to redesign color recipes and production processes in order to maintain consistency and brightness.
Supply chain transparency has also become increasingly critical. Modern certification systems extend far beyond raw material verification. They now evaluate worker safety, wage compliance, workplace conditions, emergency systems, and ethical operational practices throughout the supply chain.
Today, it is no longer enough to claim that a material is recycled or organic. Increasingly, the entire supply chain is expected to meet the same standards of accountability and compliance.
FBJ: How is sustainability reshaping decision-making at the raw material and yarn development stage?
Nicola Carletti: Sustainability is no longer a market trend — it has become a core industrial responsibility influencing every stage of yarn development.
MIC Spa has expanded beyond conventional fibers by exploring responsible alternatives including recycled polyester, organic cotton, viscose, Tencel, and lyocell. The company is also evaluating the balance between durability and biodegradability depending on the intended product application.
Today, environmental considerations influence decisions ranging from raw material sourcing and supplier selection to product engineering and long-term performance evaluation.
Compared to a decade ago, responsibility and environmental impact have become central to almost every collection and manufacturing decision. Growing awareness across the fashion industry is encouraging companies to better understand not only the materials they produce, but also the broader environmental consequences associated with textile manufacturing.
FBJ: What major shifts do you foresee in the textile supply chain over the next few years?
Nicola Carletti: The textile industry is expected to become increasingly quality-focused, transparent, and consumer-conscious.
Changing European regulations, rising demand for secondhand fashion, and growing public awareness regarding sustainability and product quality are already reshaping the industry.
Future competition will not be driven by production volume alone, but by consistency, technical expertise, traceability, and long-term product performance.
Consumers are becoming more informed about what makes a garment genuinely durable and responsibly produced. As a result, transparency surrounding materials, construction methods, and manufacturing technologies will become increasingly important throughout the supply chain.
As sustainability, durability, and transparency continue to define the future of textile manufacturing, yarn producers are expected to play a far more strategic role in shaping the next generation of textile products and global supply chains.
