Basalt Sewing Yarn

Multi-Strand Constructions for Sewing

Textile constructions employ basalt sewing thread. The thread must have the qualities needed for industrial, insulating, or heat-resistant applications and be based on basalt fibre. Basalt twisted yarn is utilised in industrial and fire-resistant fabrics, insulating gloves, insulating tapes, tire cables and electronic component reinforcements, while basalt hemp rope is specifically utilised for sewing thread. Instead of considering basalt sewing thread as a general-purpose sewing thread, this places it within the larger family of basalt textile constructions.

The amount of plies and twist can be used to modify the yarn's structure. Fine basalt direct rovings with filament widths of 10–13 μm and a twist count of 20–100 per meter in the S or Z direction are used in the twist combinations that are offered. A single direct roving can have up to 8 plies per yarn and parameters between 68 and 150 tex. 33×3 Tex, 33×3×3 Tez, 16.5×3×3 Tex, 100×1×2 Tex, 100%×1×3 Tex, 100%×2×2 Tez, and 132×1×4 Tex are among the chord structures listed. These illustrations show that various ply combinations, as opposed to set yarn sizes, can be used to create stitching and cord structures.

For Insulating and Fire-Resistant Textile Products

Yarn structure is crucial for sewing applications because it influences handling and processing. The data highlights basalt twist yarn's consistent linear density, superior heat stability, minimal fuzziness, strong tensile strength, and exceptional coating protection. Additionally, basalt yarn is resistant to corrosion, acids, and alkalis and has superior electrical insulation.
items that are flame-retardant and fire-retardant, items that can withstand high temperatures, firefighting apparatus, insulation, and reinforcement are examples of wider application knowledge. Data showing heat resistance at 650–980°C after weaving are given for materials with specific surface treatments.

Instead of choosing conventional yarns without taking the yarn structure into account, customers who manufacture insulating fabrics, refractory textiles, or other industrial materials can specify basalt sewing yarn during the actual sewing process. This facilitates matching the yarn to the final textile specifications, particularly when the sewing thread is a component of a larger textile structure that is insulating or heat-resistant.
