What effect does the source of rubber filaments have on the performance of rubber elastic yarns?

The performance of rubber elastic yarn is profoundly affected by the source of the rubber filament. This choice is directly related to the elasticity, wear resistance, comfort and sustainability of the yarn. Among them, the sources of rubber yarn mainly include natural rubber, synthetic rubber and recycled rubber.

Using natural rubber as a source for rubber elastic yarns has significant advantages in terms of sustainability. Natural rubber is a renewable resource whose harvesting process has a relatively low impact on the environment. In addition, natural rubber generally has excellent elasticity and resilience, providing rubber elastic yarns with excellent stretchability and excellent elastic properties in textiles.

In comparison, synthetic rubber as a source of rubber elastic yarn may offer more control and customization, but is less sustainable. Synthetic rubber generally excels in abrasion resistance and durability, so may be more suitable in certain applications, such as sportswear.

In addition to the source of the rubber filaments, the performance of rubber elastic yarns is also affected by the mix of materials and processing additives. Manufacturers may use blends of materials, including rubber filaments mixed with other fibers, to tailor the yarn's properties. Treatments and additives used during production may also have an impact on the properties of the final yarn, so these factors need to be considered together.
