Process-led selection
Application, machine and operating conditions form the starting point for selection.
MALKOP
Spiral Twist
Twisted cords for technical applications, packaging and industrial processes.
Construction and supply
Matched to the process
- Materials
- Polyester PET; Cotton / PET Blend
- Construction
- Twisted cord, twist parameters by variant.
- Typical diameter
- Up to approx. 3 mm, by variant
- Possible windings
- Spools, rolls and prepared lengths.
- Quantity and lead time
- Quotation and lead time after confirming the variant, winding and batch size.
The sales range includes Spiral Twist 1800, with outer packaging described as a carton of 24. Composition, twist parameters and ordering units are confirmed for the specific variant; 1800 is a product designation, not a declared length.
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.
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.
