The difference between composite and filament

First, the raw materials of composite silk and filament are different

A composite filament is a mixture of two or more different polymers with two or more properties. The filament is a single polymer material, such as polyester, polyamide and so on. Therefore, the raw material of composite silk is more complex than that of filament. The raw material of composite silk can be a fiber of different materials, such as nylon and polyester blend, or it can be a fiber of the same material, such as different grades of polyether ester. The raw materials of filament are mostly polyester, polyamide and other polymer materials.

Second, the production process of composite silk is different from that of filament

The production process of composite silk is more complicated than that of filament, which requires mixing, spinning, fabric organization and other processes. Filament is directly through high temperature and high pressure melting conversion to grow silk, do not need to go through the composition mixing and other processes. Therefore, the production process of composite silk is more complicated and more expensive than that of filament silk.

Third, the physical properties of composite silk and filament are different

The physical properties of composite silk are superior to those of filament silk. Composite silk is composed of fibers of different materials and has two or more properties, such as wear resistance, heat resistance, corrosion resistance, antistatic and so on. Filament is made of a single material, and its physical properties are relatively simple. However, the tensile strength of the filament, the strength and stiffness of the synthetic fiber are better than that of the composite silk.

Fourth, the use of composite silk and filament is different

Because of its superior physical properties such as wear resistance, heat resistance and corrosion resistance, composite silk is widely used in the production of high-end textiles such as high-end coats and tennis racket strings. Filament is more used in high-end fabrics, underwear and other fields.

In summary, although composite silk and filament are important varieties of fiber products, there are differences in the production of raw materials, processes, physical properties and uses. According to different needs, suitable fiber products can be selected.
