赤外線防止、紫外線防止、偽造防止ヤーン:今日、なぜそれらが重要なのか
GokitaQuick Answer: Anti-infrared yarn reduces or masks an object's heat signature, anti-UV yarn limits ultraviolet transmission or degradation, and anti-counterfeit yarn adds a covert or visible security feature to textiles. These functional yarns are used in military and security textiles, outdoor gear, branded goods and protective apparel. They can be specified individually or combined depending on the threat and application.
Frequently Asked Questions
How is anti-UV yarn made, and what does UPF tell a buyer?
Anti-UV yarn is engineered to block ultraviolet radiation. Manufacturers add minerals such as titanium dioxide or zinc oxide, or apply special chemical treatments, to raise the fiber's UV protection. The UPF rating indicates the performance level of the finished fabric, with higher ratings blocking more UV. Buyers should confirm the UPF rating for the specific fabric they plan to produce rather than relying only on a yarn-level description.
What is the difference between anti-infrared yarn and anti-UV yarn?
Anti-infrared yarn is designed to reduce or mask an object's heat signature, so it is used in military textiles, uniforms and equipment where concealment from infrared imaging matters. Anti-UV yarn addresses sunlight instead, blocking ultraviolet wavelengths of 10-400 nanometers for outdoor clothing, curtains, parasols and agricultural covers. The two products solve different problems and are specified against different performance criteria.
How do anti-counterfeit yarns work, and where are they used?
Infrared anti-counterfeit yarns contain special pigments or particles that react under infrared light, revealing hidden patterns or colors. Ultraviolet anti-counterfeit yarns are embedded with fluorescent substances that glow under UV lamps. Both look ordinary to the naked eye but add a security layer detectable only with specific devices. Typical uses include labels, certificates, branded apparel and currency.
