Three Properties, Three Approval Questions
UPF relates to ultraviolet transmission through a textile. Water repellency describes resistance to surface wetting, while breathability may refer to air permeability or moisture-vapor transfer. One result does not prove the others.
Dense construction can improve coverage but may reduce airflow. An open lightweight knit may feel cooler but require fiber, color or finishing adjustments to achieve the intended UV performance.
Color, Stretch and Wet Conditions Matter
UPF can change with shade, construction, extension, moisture and laundering. Test the relevant production color and, for close-fitting garments, consider the stretched state expected during wear.
Durable water-repellent finishes should be reviewed for initial spray behavior and retained performance after the agreed wash cycle. Chemistry or compliance restrictions for the destination market should be confirmed before selection.
Approve the Final Material System
Specify target weight, coverage, stretch, UPF rating, water-repellency method, air or vapor test where needed, and laundering conditions. Confirm hand feel and garment comfort after performance requirements are met.
The final garment can introduce seams, mesh panels, perforation or print areas that behave differently from the base fabric, so product-level review remains necessary.
Suitable Activewear Applications
Outdoor tennis apparel, running tops, cycling jerseys, rash guards, lightweight training layers and sun-protective activewear.

Buyer FAQ
Is water-repellent fabric waterproof?
No. Surface repellency helps water bead and roll off, while waterproof performance normally requires different construction, coatings or membranes and seam controls.
Does a dark color always have a higher UPF?
Color can influence UV transmission, but fiber, density, thickness, stretch, moisture and finishing also matter. The finished color should be tested.
Can breathable fabric still provide sun protection?
Yes, but airflow and UV coverage must be balanced through the chosen yarn, knit and finish rather than assumed from appearance.
Send the Fabric Requirement
Include the garment category, target market, expected quantity, composition or hand-feel reference, required performance, color plan and applicable test method. CCLIYA can then review the development route, sampling scope and evidence needed before bulk approval.
