OHZEHN-TEX vs Kintra: Bio-Nylon vs Bio-Polyester
Different chemistry families. Different sweet spots. Not a zero-sum fight.
OHZEHN-TEX™ is bio-nylon (PA6.10 from castor oil). Kintra is bio-polyester (PBS/PBST from corn), engineered for silky drape and industrial-composting biodegradation. OHZEHN-TEX wins leggings, sports bras, swim, and shapewear. Kintra wins base layers, lounge, and drape-driven pieces. They are complementary chemistry families, not substitutes. Pick by end-use, not by brand affinity.
1. The chemistry, in one paragraph each
OHZEHN-TEX™ (bio-nylon, PA6.10)
OHZEHN-TEX is a bio-based performance fabric platform built on PA6.10, a bio-based polyamide polymerized from castor-oil-derived sebacic acid.
Kintra Fibers (bio-polyester, PBS / PBST)
Kintra is a Brooklyn-based bio-polyester program building fibers in the PBS (polybutylene succinate) family from corn-derived succinic acid. The chemistry is bio-polyester, not bio-nylon. Mechanical profile is polyester-class with a softer, drapier hand than PA6.10, and PBS-family polymers biodegrade under industrial-composting conditions. Positioning is centered on drape-driven and end-of-life-focused applications. Production is scaling.
2. Side-by-side comparison
| Attribute | OHZEHN-TEX™ | Kintra |
|---|---|---|
| Chemistry family | Bio-nylon (PA6.10) | Bio-polyester (PBS / PBST) |
| Feedstock | Castor oil → sebacic acid | Corn → succinic acid |
| Hand and drape | Firm, tight-face | Silky, drapey |
| MOQ | Quoted against a real style on a call | Published MOQ varies by grade |
| Pricing | Quoted against a real style on a call | Case-by-case, not publicly published |
| Lead time | Quoted against a real style on a call | Varies with production scale |
| Best fit | Activewear, intimates, swim, shapewear, seamless | Base layers, lounge, drape-driven, biodegradation-focused |
Pick by end-use: stretch-heavy (leggings, bras, swim, shapewear) → PA6.10 bio-nylon. Drape-heavy or biodegradation-focused (base layers, lounge, woven) → PBS bio-polyester.
3. Why the chemistry family drives the pick
Founders shopping "plastic-free performance fabric" often collapse the category into a single option. That collapse costs money. The chemistry family drives the mechanical profile, and the mechanical profile drives whether the finished garment holds up.
If the product is stretch-heavy: leggings, sports bras, swim bottoms, compression shorts, shapewear, seamless intimates. Bio-nylon (PA6.10) is the pick. PBS-family bio-polyester has not yet demonstrated compression-grade rebound at scale.
If the product is drape-heavy: base layers, lounge sets, lightweight lounge dresses, drape-forward silhouettes. Bio-polyester (PBS/PBST) delivers a softer hand than bio-nylon. It is the closer analog to silk-like drape without silk's cost, and it biodegrades cleanly in industrial-composting conditions.
If the product needs true end-of-life biodegradation as the primary story: Kintra's PBS-family chemistry has an established composting profile today (per Kintra's published biodegradation certifications).
4. Where Kintra wins
- End-of-life biodegradation certification maturity. PBS-family chemistry has an established industrial-composting profile today.
- Drape-driven categories. Silky hand, softer recovery, closer to the aesthetic profile of viscose or silk than PA6.10 will deliver.
- US-founded narrative. Brooklyn-based, US-founded story fits certain brand narratives more cleanly.
5. Can a program use both?
Yes, and this is the answer we give when a brand's line spans both stretch-heavy and drape-heavy pieces. A leggings program on OHZEHN-TEX bio-nylon and a matching lounge program on Kintra bio-polyester is a reasonable dual-source setup.
The mistake to avoid is picking one chemistry for the whole line by default. The chemistry needs to match the end use, or the brand ships a fabric that under-delivers on one category to keep supply-chain simplicity.

6. What about Fulgar EVO and Solvay Amni Soul Eco?
Both are relevant reference points. Fulgar EVO uses PA6.10 chemistry. Solvay Amni Soul Eco is petroleum-derived PA6.6 with a biodegradation additive, not bio-based; it is Brazil-based.
7. Frequently asked questions
What is the difference between OHZEHN-TEX and Kintra?
OHZEHN-TEX is bio-nylon (PA6.10) polymerized from castor-oil-derived sebacic acid. Kintra is bio-polyester (PBS or PBST family) polymerized from corn-derived succinic acid. Different chemistry families with different mechanical profiles: OHZEHN-TEX fits activewear, intimates, swim, and shapewear. Kintra delivers silky drape and industrial-composting biodegradation for base layers and drape-driven pieces.
Which is better for leggings, OHZEHN-TEX or Kintra?
OHZEHN-TEX for leggings. Bio-nylon is the compression-grade chemistry family.
Which is better for base layers or drape-driven pieces?
Kintra for base layers where silky hand and softer drape are the priority. PBS-family bio-polyester delivers a softer, more fluid feel than PA6.10. It is also industrial-composting biodegradable, which fits programs built around end-of-life storytelling. For any piece where compression is not required, PBS is a strong pick.
What are the MOQ and pricing on OHZEHN-TEX compared to Kintra?
Kintra does not publish public pricing; MOQ varies by grade and requires a direct conversation.
Can a brand run both chemistries in one line?
Yes. A leggings program on OHZEHN-TEX bio-nylon and a matching lounge program on Kintra bio-polyester is a reasonable dual-source setup. Picking one chemistry for the whole line by default usually means one category under-delivers.
