Technical data

Technical threads and cords

Variant selection starts with application, expected winding and process requirements.

Discuss the specification
A raw-material property is not a finished-product test result

Material data supports preliminary selection. Product behaviour also depends on construction, diameter, finish and process conditions. Critical applications require tests and documentation for the exact variant.

Parameters to agree

A complete specification of the following parameters has not been published for this family. They are agreed for the selected construction and operating conditions; they must not be treated as verified properties.

  • Component yarn count · Ne / Nm
  • Finished-product linear density · tex
  • Number of component yarns · PLY
  • Twist · S/Z · TPM
  • Breaking force
  • Elongation
  • Length per unit mass
  • Operating temperature

Materials and application limits

Cotton

A natural cellulose fibre for processes where non-melting behaviour and a confirmed food-contact or useful-heat variant matter.

Heat
Oven or smoking use after variant confirmation
Flame
Does not melt; chars and may burn
Moisture absorption
High
  • Cotton does not melt, but it is not fire resistant.
  • Useful-heat suitability applies only to a variant confirmed for the process.
  • Food and candle uses require variant-specific documentation and testing.
Material evidence
Non-thermoplastic degradation and charring
Cotton does not have a thermoplastic melting point. It decomposes, chars and can burn; treatment and fibre history materially change the thermal pathway.Material-level hazard screening only. Do not convert decomposition data into a continuous-use temperature for a Malkop product.
Commercial moisture regain
8.5% commercial regain reference. This is a defined trade value, not a measured equilibrium result for a specific Malkop lot.Commercial mass and directional comparison only.
Wet tenacity change in cited fibre sample
+27.6% for the cited cotton fibre sample. The paper's yarn results vary with yarn count and structure, so this value is not universal for yarn or cord.Fibre-level directional evidence. Test the exact yarn, cord, knot and conditioning state.
Cellulosic response to flame
Cellulosic textiles can char, flame and continue glowing. Non-melting does not mean flame resistant.Hazard communication only; not a classification of a Malkop product.
Documentation and parameter verification plan

Approval for a particular application requires an approved specification, tests and documents. This sheet is not a certificate.

ISO 139 — conditioning atmosphere, ISO 2060 — linear density, ISO 2061 — twist, where applicable, ISO 2062 or ASTM D2256 — breaking force and elongation, after scope check, Customer process trial

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.
