High silica continuous yarn is meticulously processed from acid-treated and heat-treated glass fiber yarn.This specialized yarn finds versatile applications in weaving, sewing, bundling, and wrapping within high-temperature textiles. Renowned for its exceptional durability and thermal protection, it serves as a vital component in insulation, sealing, and industrial settings. From sleeves to sewing threads and electronic cigarette cores, this yarn offers reliability in demanding environments, providing effective heat resistance and insulation. It is mainly used in weaving, sewing, bundling, winding heating wires and heating elements, thermal insulation materials, seals, etc., such as casing, sewing thread, electronic cigarette cores.
 
Feature:
High Silica Content:
The yarn is made from a material that contains a very high percentage of silica (SiO₂), making it highly resistant to high temperatures, often exceeding 1000°C (1832°F). This gives the yarn superior thermal insulation properties.
Thermal Resistance:
Because of its high silica content, the yarn is particularly useful in applications that require materials to withstand extremely high temperatures, such as in aerospace, industrial furnaces, or fire-resistant materials.
Lightweight and Flexible:
Despite its high thermal resistance, high silica continuous yarn is relatively lightweight and flexible, which makes it easy to weave into fabrics or use in various forms, such as ropes, cords, or tapes.
Chemical Resistance:
In addition to thermal properties, HSCY offers resistance to various chemicals, making it suitable for use in harsh environments.
Electrical Insulation:
The yarn is also an excellent electrical insulator, which makes it valuable in situations where electrical conductivity needs to be avoided.
 
Application:
Thermal Insulation:
HSCY is widely used in industries where high temperatures are a concern, such as in the production of heat shields, insulation for furnaces, and industrial kiln linings.
Protective Clothing:
It is also used in the manufacture of heat-resistant clothing and safety gear, such as gloves, aprons, and jackets for workers in industries dealing with high temperatures (e.g., steel production, glass manufacturing).
Aerospace:
The yarn is utilized in the aerospace industry for thermal insulation in space vehicles, aircraft, and parts exposed to extreme heat.
Fireproof Fabrics:
HSCY is used to create fire-resistant textiles, such as protective garments for firefighters and other first responders, as well as fireproof curtains or blankets.
 
Cable Insulation:
High-silica yarn can be used as an insulation material for electrical cables, providing protection against high temperatures and electrical faults.
