What Are The Advantages Of Air-encased Yarn Over Other Elastic Yarns?

Air-encased yarn offers significant advantages over other elastic yarns. Its core spandex yarn provides high elasticity and good elastic recovery, and the outer filament coating provides more stable elasticity. Compared to some pure spandex yarns, the outer filaments of air-encased yarns limit excessive stretching, preventing elastic fatigue and extending the yarn's service life. Regarding durability, the outer filaments protect the spandex yarns, reducing friction and wear, and enhancing the yarn's overall strength. For example, during frequent wear and washing, air-encased yarns are more resistant to friction and are less likely to pill and break than some unprotected elastic yarns. In terms of feel and appearance, air-encased yarns, thanks to the diverse materials of their outer filaments, can exhibit varying textures and lusters. For example, an outer layer of nylon filaments creates a soft and smooth feel, while an outer layer of lustrous polyester filaments imparts a vibrant luster, enriching the product's appearance-something that single-material elastic yarns struggle to achieve. In terms of processing performance, air-covered yarns are easier to handle during subsequent processing, such as weaving and dyeing, due to the presence of the outer filaments. The outer filaments improve the yarn's spinnability, making the weaving process smoother, and can better absorb dyes, improving dyeing uniformity and ensuring the production of high-quality textiles.
