Description
Common applications for this sewing thread are used to sew filter bags by hand sewing, also used to sew weak alkali-resistant weave. It fulfill the need of sewing filter bags used in carbon black/ metallurgy/ cement industries .
Property:
► Produced from an extremely pure silica base yarn
► Silica based materials provide burn-through protection from molten metal and weld splatter
► Used at 1100°C continuously , molts above 1700℃
► Highly flexible and virtually no shrinkage
► High abrasion resistance and tensile strength
► Different coating available, and normally coating materials is PTFE, PU, etc.
Continuous working temp.: 1100℃degree
Short time working temp.: 1400℃degree
Instant working temp.: 1650℃degree
Roll weight around 500g/spool, 24rolls/ctn
Note:
1. Coatings (-A is uncoated thread, and the others are coated.)
2. As this silica sewing thread is leached silica(leached silica have less tensile strength), when it’s used in industrial high speed sewing machine require a transmission to limit the velocity less than 30 punches per minute to avoid to break the thread.
