Is the waterproof and breathable effect of nylon four-way elasticity good?

Release time:

2025-06-25

Some nylon four-way stretch fabrics undergo coating processes to improve their waterproof capabilities.

Coating Processing Enhances Water Resistance: Some nylon four-way stretch fabrics undergo coating processes to improve their waterproof capabilities. For example, nylon four-way stretch 70D moisture-wicking and comfortable elastic fabric can be coated to provide protection against wind and rain, preventing the penetration and absorption of water droplets. Additionally, certain nylon four-way stretch fabrics feature a PU coating on the waterproof layer. PU coatings are porous, which allows them to be both waterproof and breathable. They are strong and can be used for very thin coatings, effectively protecting the fabric base.
Special Structural Design Aids Water Resistance: In terms of structure, the warp of some nylon four-way stretch fabrics is made of spandex fibers, while the weft includes upper weft lines located above the warp and lower weft lines situated below the warp. The upper weft lines are made of nylon fibers, which have good water-resistant properties. Furthermore, a patent mentions a nylon four-way stretch fabric with an elastic layer on the side of the main layer facing the lower weft lines. The elastic layer is equipped with breathable pores, which also contribute to water resistance to a certain extent.
Composite Processes Enhance Water Resistance: Nylon four-way stretch fabrics that utilize composite processes exhibit superior water resistance. For instance, a composite fabric made by bonding a TPU waterproof membrane to a four-way stretch fabric and then attaching it to fleece has excellent water resistance. The TPU waterproof membrane boasts excellent wear resistance, tear resistance, low-temperature resistance, and good biocompatibility. Its water pressure resistance can reach 5000-20000 mmH₂O, effectively preventing water penetration.

Breathable Performance

Intrinsic Material Properties Facilitate Breathability: The inherent properties of the fibers and the weaving structure of nylon four-way stretch fabric contribute to its breathability. For example, nylon four-way stretch 70D moisture-wicking and comfortable elastic fabric is inherently breathable, allowing it to quickly wick away sweat from the skin and maintain dryness.
Special Fiber Components Enhance Breathability: Some nylon four-way stretch fabrics incorporate special fiber components to further enhance breathability. For example, a patent mentions a nylon four-way stretch fabric with lower weft lines made of moisture-absorbing and breathable fibers, which provide good breathability and sweat absorption.
