Why Bio Based Materials Matter in Garment Manufacturing Today

Men’s and Women’s Apparel

As the global fashion industry continues to shift toward climate responsibility, the use of bio based materials and sustainable fashion materials has become essential. Gen Z consumers are placing pressure on brands to choose eco-friendly clothing materials that reduce carbon footprint, save water, and eliminate dependence on fossil fuels.

Across activewear, loungewear, and everyday essentials, brands are increasingly seeking bio based fabrics that provide performance, comfort, and long‑term sustainability. Innovations such as bio based fibers and bio wicking technologies bridge the gap between functionality and environmental responsibility, offering advanced solutions for conscious apparel manufacturing.

Moisture management is now a top requirement for comfort driven apparel. Bio wicking fabrics deliver moisture transport and quick drying performance without relying on conventional synthetic chemical treatments. For circular knit garments such as T shirts, yoga sets, sports tops, and loungewear, consumers increasingly expect fabrics that keep the body dry in an environmentally responsible way.

Bio-wicking refers to a fabric’s ability to move moisture away from the skin, distribute it across the fabric surface, and promote faster evaporation. Unlike traditional treatments, bio wicking can be achieved through the natural structure of bio based materials or the use of plant derived moisture management technologies.

At Thai Son S.P, bio-wicking performance is further enhanced through the application of ProTecht® PMM, a bio-based moisture management solution derived from castor seed. When applied to circular knit fabrics, this technology supports durable moisture transport and quick-drying performance while aligning with sustainability goals.

As brands move away from petroleum based fibers, bio based materials such as bio nylon and bio spandex offer responsible alternatives with reduced environmental impact.

These eco-friendly clothing materials maintain the stretch, comfort, and durability expected in modern apparel while reducing reliance on fossil fuels.

Spandex, also known as elastane, is typically used in small percentages in knit garments, usually ranging from 3 to 15 percent, but it plays a critical role in providing comfort, stretch, and shape retention. Bio-based spandex is produced using biological carbon derived from renewable sources such as sugarcane or corn starch, helping reduce reliance on fossil-based inputs

In apparel manufacturing, bio-based spandex is often blended with cellulosic fibers to enhance softness and breathability. At Thai Son S.P, bio-based spandex is combined with certified Lenzing TENCEL™ Modal to create circular knit fabrics that offer long-lasting elasticity, a smooth handfeel, and reliable recovery without sagging.

This bio based fabric blend is well suited for form-fitting garments, yoga wear, loungewear, and sustainable intimates. For brands focused on sustainability, the use of Lenzing TENCEL™ Modal blended with bio-based spandex supports objectives such as carbon footprint reduction, PFAS elimination, and increased use of certified, bio-preferred materials.

At Thai Son S.P, bio-based nylon and spandex are applied in circular knit fabrics and cut-and-sew garments for export markets, with the following characteristics:

• Compatibility with lightweight structures
• Easy dyeing and finishing
• Excellent stretch and recovery
• Soft, breathable touch
• High durability for performance wear

Bio based materials allow brands to maintain quality with a significantly lower environmental footprint.

In sustainable apparel development, innovation is most effective when different systems work together. One of the strongest examples is the combination of bio based materials with bio wicking technology. While bio wicking focuses on moisture management using biological or plant derived inputs, bio based fabrics such as bio nylon and bio spandex provide the functional foundation needed for these technologies to perform reliably in circular knit garments.

These eco-friendly clothing materials naturally enhance moisture transport, breathability, and wearer comfort, making them ideal for performance driven sportswear, yoga apparel, and active essentials.

Bio based nylon and bio based spandex have optimized molecular structures that make them highly compatible with bio wicking finishes derived from natural sources such as amino acids, sugars, and vegetable oil based treatments. These sustainable fashion materials absorb finishing agents more effectively and retain them longer, resulting in stable moisture management even after repeated washing and long term wear. This compatibility is especially valuable in circular knit fabrics, where consistent moisture control and elasticity are essential for both performance and comfort.

When bio based materials are paired with bio wicking technologies, the result is a new generation of knit garments that balance performance, skin comfort, and environmental responsibility. This material synergy helps:

• Reduce the use of traditional petroleum based chemicals
• Support cleaner and safer finishing processes
• Enhance garment durability
• Enable more circular design strategies, including improved recyclability and biodegradability

This approach is widely used by forward thinking brands and eco friendly clothing manufacturers for garments such as activewear, yoga sets, athleisure, and moisture focused basics. In these categories, stretch, breathability, and quick drying properties play an essential role in daily comfort.

As the textile and garment industry works to reduce its environmental footprint, bio-based materials have become an increasingly important solution. Sourced from renewable inputs such as castor beans or corn glucose, bio-based nylon and spandex offer a lower-impact alternative to conventional petroleum-based synthetics while maintaining the quality, durability, and performance required for modern knit garments.

• Reduced Carbon Emissions

Producing bio-based nylon can reduce greenhouse gas emissions by up to 60 percent compared to petroleum-based nylon (Source: BASF Technical Paper, 2023). This is because bio-feedstocks absorb CO₂ during cultivation, partially offsetting emissions during polymerization.

• Lower Water and Energy Usage

Bio-based materials often require less irrigation and lower processing temperatures, saving both water and energy. For example, castor plants used in nylon 11 need no artificial irrigation and thrive in semi-arid regions.

•  Less Dependence on Fossil Fuels

Shifting from oil-derived synthetics to bio-based alternatives helps diversify raw material sources and reduce fossil fuel dependency. This aligns with global climate targets and supports long-term supply chain resilience.

• Biodegradability & Circularity Potential

Some types of bio-based spandex (such as partially bio-based polyurethane) are being developed with enhanced biodegradability, which may offer better end-of-life options than conventional elastanes. Combined with bio-wicking finishes and mono-material design, these innovations pave the way for more circular knit garments.

Bio based materials can be used in a wide range of circular knit products, making them highly versatile for sustainability focused brands. From activewear and yoga pieces to underwear, swimwear, and everyday basics, these materials provide stretch, breathability, and shape retention. Lightweight, durable, and eco-conscious, they are ideal for slow fashion and mindful consumers.

1. Do bio based fabrics provide the same comfort and durability as conventional fibers?

Yes. Modern bio based fabrics offer comfort, stretch, and durability comparable to traditional synthetics. In many cases, they provide superior breathability and moisture management.

2. Which garments are best suited for bio wicking and bio based materials?

Bio based materials work well in:

• Activewear and sports tops
• Yoga leggings(https://thaisonsp.com/womens-wear/yoga-apparel-factory-in-vietnam/)
• Performance T shirts
• Loungewear
• Intimates
• Athleisure clothing

They are especially effective where moisture control and stretch are key.

3. How do bio based fabrics reduce carbon footprint and water usage?

Bio based fabrics use renewable feedstocks that absorb CO₂ during cultivation. Plants like castor require no artificial irrigation, reducing water usage. Their lower processing temperatures also save energy.
