What is Sorona? The Plant-Based Performance Fabric Explained

Melissa Yearta January 6, 2026

If you've been following the shift toward non-toxic fashion, you've probably noticed more brands mentioning "plant-based" or "bio-based" performance fabrics. One of the most innovative is Sorona—a stretchy, durable, high-performance material that's made from plants, not petroleum.

But what exactly is Sorona? How is it different from conventional polyester or nylon? And most importantly—is it actually better for you and the environment?

Here's everything you need to know about this game-changing fabric.

What is Sorona?

Sorona is a plant-based performance fiber created by DuPont using renewable plant materials instead of petroleum-based chemicals.

The Basics:

Made from: Corn-derived sugar (specifically, 37% plant-based content)
Performance: Stretch, recovery, softness, durability
Feel: Soft, smooth, buttery hand-feel
Uses: Activewear, athleisure, swim, performance apparel
Certifications: Oeko-Tex Standard 100, Greentex certified

The key difference: While conventional nylon and polyester are made entirely from petroleum (oil), Sorona uses renewable plant materials for a significant portion of its polymer structure.

How is Sorona Made?

The Plant-Based Process:

Step 1: Grow the corn

Field corn (not food-grade sweet corn) is grown using sustainable farming practices
No competition with food supply
Uses land not suitable for food crops

Step 2: Extract the sugar

Sugar is extracted from corn kernels
Fermentation process converts sugar into 1,3-propanediol (PDO)
This is the plant-based building block

Step 3: Create the polymer

PDO is combined with petroleum-based terephthalic acid
Forms polytrimethylene terephthalate (PTT) polymer
Extruded into fibers

Step 4: Weave into fabric

Sorona fibers are blended with other materials (often recycled polyester)
Woven or knit into performance fabric
Finished with [Oeko-Tex certified dyes](link to Oeko-Tex blog)

Result: A performance fabric that's 37% plant-based with significantly lower environmental impact than conventional synthetics.

Environmental Benefits of Sorona

This is where Sorona really shines compared to conventional performance fabrics.

Energy Savings

37% less energy to produce than nylon
30% less energy than conventional polyester

Why this matters: Conventional synthetic fabric production is incredibly energy-intensive, contributing significantly to fashion's carbon footprint. Sorona's plant-based content requires less processing energy.

Reduced Greenhouse Gas Emissions

63% lower greenhouse gas emissions than nylon
56% lower emissions than conventional polyester

The impact: Choosing Sorona over nylon = same as taking a car off the road for 45 days per ton of fabric produced.

Renewable Resource Use

Uses plant-based materials (renewable annually) instead of petroleum (finite resource)

Closed-loop fermentation: The process to create PDO from corn sugar is highly efficient with minimal waste.

Water & Land Use

Minimal water use in production (compared to conventional cotton or polyester dyeing)
Non-food corn: Grown on land not suitable for food crops
No pesticides in production: Unlike [conventional cotton](link to BCI blog), the corn isn't treated with harmful chemicals

Performance Benefits of Sorona

Sustainability is important—but performance matters too. Sorona delivers.

1. Exceptional Stretch & Recovery

4-way stretch: Moves with you in all directions
Shape retention: Returns to original shape after stretching
No sagging: Maintains fit wash after wash

Perfect for: Yoga, running, lounging, everyday wear

2. Buttery Soft Hand-Feel

Smooth texture against skin (not scratchy like some polyester)
Luxurious feel without the luxury price tag
Comfortable all day for both active and casual wear

Why this matters: You're more likely to actually wear comfortable clothing—extending garment life and reducing consumption.

3. Moisture-Wicking & Quick-Drying

Pulls moisture away from skin during activity
Dries quickly (great for travel, gym-to-errands)
Breathable (doesn't trap heat like conventional polyester)

Without chemical treatments: Unlike many "moisture-wicking" fabrics that achieve this through chemical finishes, Sorona's performance is inherent to the fiber structure.

4. Color Retention

Vibrant colors that don't fade
Stain-resistant naturally (without PFAS treatments)
UV resistant (colors stay true in sun exposure)

Long-term value: Looks newer, longer—reducing need to replace frequently.

5. Durability

Abrasion-resistant (doesn't pill or wear thin)
Maintains integrity through repeated washing
Long lifespan (years of regular use)

Cost-per-wear: Higher upfront cost = lower long-term cost due to longevity.

How to Care for Sorona Fabric

Proper care extends the life of your Sorona garments and maintains performance.

Washing Instructions

1. Machine wash cold

Preserves elasticity and color
Reduces energy consumption
Prevents shrinking

2. Use gentle cycle

Protects fabric integrity
Reduces wear and tear
Maintains shape retention

3. Avoid fabric softener

Fabric softener coats fibers and reduces moisture-wicking
Unnecessary—Sorona is naturally soft
Can cause buildup over time

4. Wash with similar colors

Prevents color transfer
Keeps colors vibrant
Protects light-colored items

Drying Instructions

1. Line dry when possible (BEST)

Extends garment life significantly
Sorona dries quickly (1-2 hours)
Zero energy consumption

2. Tumble dry low (if needed)

Low heat only (high heat can damage elasticity)
Remove promptly to prevent wrinkles
Use dryer balls (skip dryer sheets)

3. Never use high heat

High heat breaks down stretch fibers
Causes shrinking
Reduces lifespan

Storage Tips

Fold activewear (hanging stretches it out)
Don't store damp (wash after workouts, dry completely)
Keep out of direct sunlight (prolonged UV exposure fades colors)
Rotate items (don't wear the same piece every day)

Expected lifespan with proper care: 3-5+ years of regular use

Frequently Asked Questions About Sorona

Is Sorona toxic or safe to wear?

Sorona is safe when Oeko-Tex certified (like all HYPEACH Sorona products). The Oeko-Tex Standard 100 certification tests for 350+ harmful substances, ensuring no toxic chemicals remain in the finished fabric. While the production process uses chemicals, proper certification ensures they don't remain in the garment.

Does Sorona shed microplastics like regular polyester?

All synthetic fabrics can shed some microfibers during washing, including Sorona. However, the tighter weave and higher quality of Sorona fabric typically sheds less than low-quality conventional polyester. To minimize: wash less frequently, use a Guppyfriend bag, and choose high-quality Sorona blends.

Can you recycle Sorona fabric?

Yes, Sorona is recyclable through textile recycling programs that accept synthetic fabrics. HYPEACH is launching a clothing recycling program in Q1 2026 where you can return worn HYPEACH items for responsible recycling.

Is Sorona vegan?

Yes, Sorona is vegan—it's made from corn-derived plant materials and petroleum-based chemicals. No animal products or by-products are used in production.

How do I know if clothing contains Sorona?

Check the care label for "Sorona" or "PTT" (polytrimethylene terephthalate). Brands using Sorona typically mention it prominently because it's a performance advantage. All HYPEACH athleisure clearly states "52% Sorona + 48% recycled polyester."

Is Sorona better than Tencel or modal?

Different use cases. Tencel/modal (made from wood pulp) is great for soft, drapey clothing but has minimal stretch. Sorona excels for activewear requiring stretch, recovery, and moisture-wicking. For casual dresses, choose Tencel. For leggings and sports bras, choose Sorona.

Why isn't Sorona 100% plant-based?

Current technology allows for 37% plant-based content in the polymer structure. The remaining percentage requires petroleum-based chemicals to achieve the performance properties (stretch, durability) consumers expect. DuPont continues researching ways to increase renewable content.

The Future of Plant-Based Performance Fabrics

Sorona represents an important step toward more sustainable activewear, but it's not the final destination.

What's Next:

Increased renewable content: Research continues into 50%+ plant-based performance fabrics
Alternative crops: Beyond corn—hemp, sugarcane, and algae-based polymers
Closed-loop recycling: Technology to infinitely recycle performance fabrics
Biodegradable synthetics: Performance fabrics that break down safely at end of life

HYPEACH's commitment: As new sustainable performance fabrics emerge, we'll evaluate and adopt those that meet our standards for safety, performance, and environmental impact.
