nylon high elastic yarn 70D & 140D: exploring the infinite possibilities of spandex covered yarn
In this era of comfort and functionality, high-performance fibers have become an integral part of many industries. Among them, nylon high elastic yarn stands out with its excellent elasticity, strength and softness, especially in the field of sportswear, underwear and other fabrics that require high strength and elasticity.

Secret High Performance Fiber: The Core Advantage of Nylon High Elastic Yarn
Nylon high elastic yarn is a composite material composed of nylon filament and spandex core. Its core lies in "high elasticity", which not only enables it to easily adapt to changes in human movement, but also ensures its recovery after long-term wearing. In addition, the material has good abrasion resistance and wrinkle resistance, and will not lose its original shape and feel even after repeated washing.
Performance from Data: 70D vs 140D Differences and Applicable Scenarios
In practical applications, nylon high-elastic yarns are usually divided into two specifications-70D and 140D. Although the two belong to the same family, there are obvious differences in specific manifestations:
70D: More light and delicate, suitable for making tights or close-fitting wear products.
140D: is more thick and firm, suitable for outdoor activities such as mountaineering clothing or ski clothing and other products against harsh environments.
New definition of elasticity: the road to technological innovation of spandex covered yarn
The traditional single line has been unable to meet the needs of modern consumers for diversification, and the use of the latest technology developed spandex covered yarn has completely changed this situation. By using spandex as an internal support framework and uniformly winding one or more layers of nylon fibers on the outside, the effect of retaining the original advantages of flexibility and greatly improving the surface smoothness is achieved.
Practical Case Sharing: Successful Application of Nylon High Elastic Yarn in Various Fields
At present, a large number of brands on the market have begun to widely use this new fabric to create their main product series. For example, the fitness suit of a well-known sports brand relies entirely on the powerful resilience provided by this magical substance to help athletes complete various complex movements without any sense of restraint. Another example is that some high-end lingerie manufacturers have joined the ranks one after another, using its super-strong flexibility to enable every customer to enjoy an unprecedented extreme experience.
