Production
The seed hairs of the cotton plant are processed through various production steps to form a fibre fleece (rovings), which is then spun into a finished yarn.
Properties
- The longer the fibres, the more valuable and the higher the strength
- Shiny after mercerisation
- Low tear resistance
- Low elasticity
- Medium moisture absorption
- High tendency to crease
- Resistant to organic solvents, loss of strength due to strong alkalis, dissolution and decomposition by acids
Temperatures
- decomposes or ignites at 400°C, does not melt, burns easily, smells like burnt paper
FAQ
-
Cotton sewing threads are produced from the seed hairs of the cotton plant. The fibres are processed into a fibre fleece (rovings) and then spun into yarn.
-
Longer cotton fibres result in higher strength and better yarn quality. Fibre length is a key factor in determining performance.
-
Yes. Mercerisation increases the lustre of cotton and improves its appearance, making it more suitable for decorative and high-quality applications.
-
Compared to synthetic fibres, cotton has relatively low tear resistance. It is suitable for many applications but not for high-performance technical uses.
-
Cotton has low elasticity. This means it offers limited stretch and recovery compared to synthetic alternatives.
-
Cotton has medium moisture absorption. It can absorb humidity, which influences its behaviour in certain sewing and wearing conditions.
-
Cotton is resistant to organic solvents. However, strong alkalis reduce its strength, and acids can dissolve or decompose the fibre.
-
Cotton does not melt. It decomposes or ignites at approximately 400°C and burns easily, producing a smell similar to burnt paper.
-
Cotton does not melt under heat, but it burns easily and therefore is not suitable for flame-protective or extreme heat applications.
-
Cotton threads are often used in classic apparel, decorative seams and applications where a natural fibre appearance or mercerised shine is desired.
