Does stretch fabric have the function of moisture absorption and breathability?
Whether stretch fabrics have moisture absorption and breathability mainly depends on their material combination and structural design. The following is a breakdown explanation:
1. Moisture absorption can be achieved through material blending
stretch fabrics usually use spandex as the core stretch fiber, but spandex itself has poor moisture absorption. If blended with other functional fibers (such as cotton or polyester irregular cross-section fibers), it can inherit the moisture absorption characteristics of the blended fibers. For example, polyester forms grooves through irregular cross-sections (Y-shaped, cross shaped, etc.) to absorb sweat using capillary effect, while cotton fibers directly adsorb water molecules through hydrophilic groups. This combination gives the fabric moisture absorption ability while maintaining stretchity.
2. Breathability depends on fabric structure design
The breathability of stretch fabrics is closely related to their weaving process. By using jacquard, mesh weaving, or honeycomb structure, tiny pore channels are formed in the fabric, allowing air to freely penetrate. Even with the addition of spandex, as long as the yarn density and fabric porosity are controlled (such as using single-sided yarn addition or ribbed change organization), breathability can still be maintained.
3. Hierarchical structure optimization with bidirectional functionality
High end stretch fabrics often adopt multi-layer designs: the inner layer (close fitting layer) uses hydrophobic quick drying fibers (such as fine polyester) to quickly dissipate sweat; The middle layer is an stretch support layer (spandex or stretch film); The outer layer is paired with hydrophilic fibers (cotton/adhesive) to expand the evaporation area. This structure not only ensures stretchity, but also enhances moisture absorption and sweat wicking efficiency through differential capillary effect.
4. Post organizing technology to supplement functionality
Some stretch fabrics may enhance surface moisture absorption through hydrophilic additives or coating treatments, but may sacrifice some breathability. A better solution is physical modification - such as microporous treatment of fibers to enhance their moisture permeability while retaining stretchity.
