IRR耐赤外線糸とは?高い遮蔽率とカモフラージュガイド
GokitaQuick Answer: IRR (Infrared Reflectance Reduction) yarn is a functional yarn that reduces infrared reflectance, especially in the 8–14 micron thermal band, to help military, security and outdoor products evade IR detection. It is typically made from high-strength polyester or nylon with IR-shielding additives while retaining durability and weaveability. Velve offers custom IRR yarn specifications for camouflage and protective textile applications.
Frequently Asked Questions
What base fibers and additives are used to make IRR anti-infrared yarn?
IRR yarn is typically built on high-strength polyester or nylon, with infrared-shielding additives incorporated into the fiber. This construction is chosen to retain durability, wear resistance and weaveability while reducing infrared reflectance. Because the base polymer and additive package both influence performance, buyers should confirm the exact fiber content and construction with the supplier before specifying the yarn for tactical uniforms, camouflage gear or security textiles.
Which infrared band matters for thermal camouflage, and how should IRR performance be tested?
IRR yarn is designed to reduce infrared reflectance in the thermal band, especially the 8-14 micron range used by night-vision and detection devices. Rather than accepting a single blocking percentage, ask for reflectance data across the band relevant to your sensor and environment. Test the finished fabric, color and construction you will actually use, and request the test method, batch information and consistency data before bulk production.
What specifications and customization options are available for IRR yarn?
IRR yarn can be supplied in custom specifications such as 150D/2 and 210D/3, and it remains compatible with weaving and knitting processes. Color can be customized, which helps when the yarn must match a camouflage palette or garment design. Suppliers may also support sample development so buyers can evaluate hand, color and fabric performance before committing to a production specification.
