A fiber celebrated for its sustainability, strength, and durability, hemp is increasingly popular in apparel and home furnishings. For these applications, particularly items like curtains, upholstery, and everyday clothing that face repeated sun exposure, a textile's ability to resist fading its colorfastness to light is a critical quality benchmark. This performance is internationally assessed using the ISO 105-B02 standard, which simulates the long-term effects of light exposure in a controlled laboratory environment.
