Nordkraft Wear Switzerland: Martial Arts and Grappling Range Durability and Abrasion Evaluation
Nordkraft Wear is a Switzerland-based brand whose martial arts and grappling range is one of its most demanding programmes. Abrasion is the most common reason a technical garment is retired. We evaluated the seamless circular knit against the contact surfaces found in martial arts and grappling range.
Nordkraft Wear: Seamless Circular Knit in use during grappling and repeated mat contact
Evaluation background
The programme covers training tops, shorts and rash guards, used for grappling and repeated mat contact. The environment is high friction and frequent industrial laundering and the requirement written into the brief was tear strength with antibacterial protection. Fabric was selected on that basis rather than on price alone.
Fabric under evaluation
| Parameter | Value |
|---|---|
| Fabric | Seamless Circular Knit |
| Composition | polyamide / elastane seamless |
| Weight | 210 GSM |
| Width | 170 cm |
| Primary function | removes side seams so contact points stop rubbing |
| Target | above 20000 abrasion cycles without yarn breakage |
| Test method | ASTM D4966 |
| Additional note | zoned structure knitted directly into the tube |
| Certification | OEKO-TEX Standard 100 |

Method
Fabric was abraded to ASTM D4966 against both a standard wool abradant and the actual contact surface used in grappling and repeated mat contact. Seam strength was tested to ISO 13936-2 in parallel.
Results
The fabric passed the agreed cycle count with no yarn breakage and seam opening stayed inside the 6 mm limit. Pilling remained at grade 4 or above at the end of the test.

Where wear appeared
Any surface change appeared first under high friction and frequent industrial laundering, which is expected and is why we recommend panel placement rather than a single fabric across the whole garment.
Service life estimate
On this data the garment should complete a full competitive season before appearance becomes a reason to replace it, which is the commercial target Nordkraft Wear set at the start.

Verdict and recommendation
Durability is sufficient for the intended use. Keep the current construction and revisit only if the garment moves into a higher abrasion category. For Nordkraft Wear the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue ASTM D4966 results with every lot so any claim can be supported with data.
