The types of core-spun thread mainly include the following:
Polyester core-spun thread: It is composed of polyester filament or staple fiber wrapped around the core thread. The core thread can be natural fiber such as cotton, linen, etc., or synthetic fiber such as polyester fiber, nylon, etc. Polyester core-spun thread has the advantages of high strength, wear resistance, corrosion resistance, etc., and is widely used in various fields.
Cotton core-spun thread: It is composed of pure cotton fiber wrapped around a bundle of polyester continuous filaments, which has better soft feel, color fastness, chemical resistance and wear resistance. Its tensile strength is better than that of cotton-spun polyester sewing thread, and it has good stitch heat resistance and neat sewing appearance.
Alloy cored wire: including calcium silicon cored wire, titanium iron cored wire, boron iron cored wire, calcium silicon manganese cored wire, rare earth silicon cored wire, rare earth silicon magnesium cored wire, rare earth silicon barium cored wire, rare earth silicon barium aluminum cored wire, calcium silicon barium cored wire, calcium silicon barium aluminum cored wire, metal magnesium cored wire, pure calcium cored wire, calcium aluminum cored wire, rare earth magnesium silicon calcium cored wire, carbon cored wire, etc. These alloy cored wires are mainly used in the fields of metallurgy and welding, and have specific alloy compositions and properties.
The types and application fields of these cored wires are different, and the selection of appropriate cored wires needs to be determined according to specific needs.
