For decades, nylon has been synonymous with exceptional strength, durability, and resilience. From mountaineering gear to industrial applications, its tough nature has made it an indispensable synthetic fiber. However, its traditional smooth, often slick handfeel and perceived lack of breathability have kept it distinct from the comfort and aesthetic appeal of natural fibers. An evolution is underway, as textile innovators are developing high-performance nylon fabrics and yarns that not only retain nylon's legendary strength but also beautifully replicate the refined appearance and luxurious texture of natural fibers, while offering advanced comfort and functionality.

Look beyond durability

The push for "natural-feel" nylon is due to evolving consumer demands and industry imperatives.

• Versatile performance: Consumers increasingly seek garments that seamlessly transition from high-performance activities to everyday wear, requiring fabrics that are both functional and comfortable.

• Aesthetic appeal: There's a growing desire for the sophisticated look and soft touch of natural fibers, even in technical apparel.

• Sustainability imperative: As environmental consciousness rises, the industry is pressured to reduce its reliance on virgin fossil fuels and mitigate issues like microplastic pollution, leading to innovations in recycled and bio-based nylon.

• Blending strengths: The aim is to combine nylon's inherent advantages (strength, elasticity, quick-drying) with the desirable qualities of natural fibers (softness, breathability, drape).

Engineering a softer touch

Achieving a natural aesthetic and beet comfort in nylon involves sophisticated advancements in polymer science, yarn engineering, and fabric finishing.

Advanced fiber cross-sections and denier: Traditional nylon fibers are often round and uniform. Innovations now involve creating fibers with modified cross-sections (e.g., flat, trilobal) and ultra-fine deniers (microfibers). These irregular shapes and finer filaments contribute to a softer, more textured handfeel, improved drape, and enhanced light diffusion, mimicking the subtle variations found in natural fibers.

Texturizing and spinning techniques: New texturizing processes introduce crimp and bulk into nylon yarns, giving them a softer, more voluminous feel akin to spun natural yarns. Advanced spinning methods allow for greater control over yarn structure, leading to more natural-looking and feeling fabrics.

Blending with natural or regenerated fibers: A common strategy is to create core-spun yarns where a strong nylon core is wrapped with softer natural fibers like cotton or wool. Alternatively, nylon is blended with regenerated cellulosic fibers (like Modal or Lyocell) to impart softness, breathability, and moisture management while retaining nylon's durability.

Surface modification and finishing: Specialized chemical and mechanical finishing treatments are applied to nylon fabrics to alter their surface properties. These can include brushing, sanding, or enzymatic treatments to break down surface fibers, resulting in a softer, peach-skin-like feel. Hydrophilic finishes can also be applied to improve moisture wicking.

Bio-based nylon development: A major area of innovation is the development of nylon polymers derived from renewable plant-based resources (e.g., corn, castor beans, sugarcane) rather than petrochemicals. This addresses the fossil fuel dependency and offers a more sustainable pathway.

Recycled nylon technologies: Pioneering companies are developing sophisticated processes to recycle post-consumer and post-industrial nylon waste (like fishing nets, carpets, and fabric scraps) back into high-quality nylon yarns. This circular approach significantly reduces the environmental footprint.

Hurdles in production

There are several issues while transforming nylon's traditional characteristics, while maintaining its core strength. One primary barrier to achieving a more natural aesthetic in nylon has been its inherent slickness and handfeel—that smooth, often overtly synthetic feel. However, this is being overcome through the use of microfiber technology, advanced texturizing processes, and strategic blending with natural or regenerated fibers, all of which create softer, more tactile surfaces. Additionally, specialized finishes further enhance the fabric's "hand." Another significant challenge lies in nylon's conventional breathability and moisture management; it's typically less breathable than natural fibers and can feel clammy against the skin. Innovations in fiber cross-sections now create micro-channels that improve moisture wicking, and blending nylon with absorbent fibers like cotton, Modal, or Lyocell, along with applying hydrophilic finishes, significantly enhances both breathability and quick-drying properties.

Furthermore, nylon's tendency to generate static electricity, especially in dry environments, has been a persistent issue. This is being mitigated through the application of anti-static finishes and by blending nylon with other fiber types. Beyond performance, significant sustainability concerns surround virgin nylon production, as its energy-intensive, reliant on fossil fuels, and contributes to greenhouse gas emissions and microplastic shedding. Yet, the rapid development of recycled nylon—such as Econyl, made from pre- and post-consumer waste—is proving to be a game-changer, drastically reducing the need for virgin resources and lowering its carbon footprint. The emergence of bio-based nylon offers a promising renewable alternative, and advancements in dyeing and finishing processes are further aiming to reduce water and chemical usage.

Finally, recycling blended fabrics poses a complex challenge due to the difficulty in separating nylon from other fibers. Nevertheless, companies like Aquafil are making strides, having launched a demonstration plant capable of chemically separating elastic fibers from nylon in blended fabrics, marking a significant step towards achieving full circularity for challenging textile waste streams like sportswear.

Commercial market success

The commercial market is already seeing significant success in bringing high-performance nylon with a natural look and feel to the mainstream, thanks to several innovative brands and technologies. Aquafil's Econyl Regenerated Nylon stands out as a leading example of commercially successful recycled nylon. Crafted from waste materials such as discarded fishing nets, fabric scraps, and industrial plastics, Econyl delivers the same quality and performance as virgin nylon but with a remarkably reduced environmental footprint.

Its efficacy is evident in its adoption by high-end fashion brands like Prada, Gucci, and Burberry, as well as numerous sportswear and swimwear brands, showcasing that recycled nylon can indeed meet rigorous demands for both aesthetics and performance. For instance, swimwear made with Econyl maintains its shape, color, and durability while offering a soft feel against the skin. Notably, Econyl production slashes the global warming impact of nylon by up to 80 per cent compared to material derived from virgin oil. Further expanding its reach, Aquafil launched a demonstration plant in March 2025 dedicated to separating elastic fibers from nylon, aiming to broaden the types of waste that can be recycled into Econyl.

Invista, a major nylon producer, is also making waves with its sustainable and natural-feel options, notably with Cordura re/cor and Cordura Naturalle. The Cordura re/cor collection features fabrics made from 100 per cent recycled nylon 6 (RN6) and recycled nylon 6,6 (RN66) sourced from post-industrial waste. These fabrics retain the legendary durability of Cordura while offering a more responsible choice, and their underlying yarn technologies contribute to finer, more adaptable fabrics beyond just rugged applications. Directly addressing the handfeel aspect, Cordura Naturalle is specifically engineered to provide the lightweight versatility and durability of nylon with a soft, natural touch, effectively mimicking cotton or wool.

Meanwhile, Italian yarn manufacturer Fulgar is pushing the boundaries of polyamide innovation with Nanofiber by Fulgar and Q-Geo. Nanofiber by Fulgar is an ultra-light polyamide 6.6 composed of exceptionally fine filaments (as thin as 7 microns), allowing for incredibly soft and silky fabrics that boast high opacity and lightness while maintaining abrasion resistance—directly targeting the luxurious handfeel of natural silk. Finally, Q-Geo is a bio-based polyamide yarn derived from renewable sources, offering 50 per cent better moisture management than conventional polyamide and exceptional abrasion resistance, thus combining sustainability with enhanced comfort.
