Elasticord
Braided elastic cord for tying machines and industrial processes.
Construction and supply
- Materials
- Polyester PET; Elastic core
- Construction
- Braided construction with elastic core, variants according to the product specification.
- Typical diameter
- Typically up to approx. 3 mm
- Possible windings
- Machine-ready windings, rolls, spools and customer-agreed packaging.
- Quantity and lead time
- Quotation and lead time after confirming the variant, winding and batch size.
About the product
Elasticord is selected for a specific machine, product path and process requirement. Parameters are confirmed with samples and customer-side tests.

Yarn count and twist
Ne / Nm, linear density in tex, ply count and S/Z twist with TPM describe different product characteristics. Finished-cord diameter is specified separately.
For elastic cords, we also specify the core construction, number of braid carriers and yarns per carrier. A single PLY value does not replace these details.
Textile designations and the Ne 6/3 example
- NeEnglish cotton count
- Number of 840-yard hanks per pound of yarn. Higher count means lower linear density, not diameter in mm.
- NmMetric count
- Metres of yarn per gram. Nm and Ne are different systems; Nm 6 is not the same as Ne 6.
- tex / dtexLinear density
- tex: grams per 1,000 m; dtex: grams per 10,000 m. 1 tex = 10 dtex. State whether the value applies to a component yarn or the finished product.
- PLYNumber of component yarns
- Number of yarns combined at a given plying stage. Specify each stage of a cabled construction separately; ply is not the number of individual fibres.
- S / ZTwist direction
- Direction of the twist. For plied yarns, distinguish the component-yarn twist from the final plying twist.
- TPM · turns/mTwist level
- Turns per metre. TPI means turns per inch; 1 TPI ≈ 39.37 TPM. S or Z alone does not specify the twist level.
- N / cN/texBreaking force / tenacity
- Force at break and force relative to linear density. Comparison requires consistent test methods and conditions.
- %Elongation at break
- Change in length at break. This is not the same as an elastic cord's working extension.
Designation example, not a MALKOP product specification
Ne 6/3: three Ne 6 singles, or 3 PLY. Each single is approximately 98.4 tex; the nominal total is approximately 295.3 tex before twist contraction. By comparison, Nm 6 is approximately 166.7 tex.
Conversions: tex ≈ 590.6 / Ne (cotton); tex = 1000 / Nm. Yarn count does not convert directly to cord diameter.
