Sewing thread
Sewing thread is a type of thread that is suitable for sewing .
properties
The most important properties of the sewing thread include:
- Tear, abrasion and loop resistance (tensile strength cotton thread = approx. 25 cN / tex , synthetic thread = over 70 cN / tex)
- Elongation and dimensional stability, sliding ability
Manufacturing
material
- Most sewing threads are made from polyester (PES) in all known forms ( multifilament smooth, textured and spun with cotton , monofilament , as well as long and short staple fibers ).
- Polyamide (including aramid ), elastane , polyacrylic fibers and Teflon are used for special sewing threads.
Of the natural fibers, the following are significant:
Procedure
- Most yarns are triple twisted ; Double and multiple threads (e.g. 2 × 3 twisted) are also common. Monofilaments are used for special purposes .
- All staple fiber yarns are singed
- Cotton and blends with cotton are usually bleached and mercerized .
- All sewing threads are dyed (filament threads often in the spinning mass) and are given a sliding finish (waxing agent).
Exception: monofilament yarns often remain undyed and transparent.
Presentation
In the last production stage rewinds one finished yarns in various Spulenformate- and sizes (from 40 m for domestic use up to 50,000 m for industrial sewing).
The picture on the right shows a cylindrical (front left), a conical cross-wound bobbin (rear left), front right a disc bobbin and rear right a s. G. King coil .
Description of the threads
Each bobbin has a label with information about the material composition and yarn count . The metric system ( Nm ) predominates in the numbering of yarn counts (officially abolished since 1964 ).
The fineness is often indicated on the labels under the designation No. (or No. ). In this case, the numerical information always refers to the metric Nm of a triple thread. For example a sewing thread No. 120 is either Nm 120/3 or Nm 80/2 (in both cases a final Nm 40).

Use for special purposes
- Cotton yarn: so-called raw manufacture (goods, especially trousers, are only dyed after manufacture)
- Aramid: Technical textiles (airbags, heat protection suits, work gloves, safety shoes, filters)
- Silk: elastic seams, buttonholes, sewing on buttons, leather goods, furs
- PES multifilament wrapped with metal ribbon (silver, gold): decorative sewing thread
- Teflon: chemical-resistant textiles
