Abstract

The negative effects of sunlight has been known associated with the development of skin cancer, skin aging, immune suppression, and eye diseases. The UV Index is an important parameter to alert people about the need to adopt protective measures. This paper reports a design concept and techniques developed in engineering UV indexable two-layer narrow woven fabrics. The fabrics were made using a type of photochromic yarn and three reference yarns with static colours indicating the level of UV intensity based on the measurement of colour change of the photochromic yarn under different level of UV intensities.

Introduction

Photochromic pigments were developed for colour changing lenses for sunglasses initially. Their application have been expended in innovative textile and fashion design and many other applicable areas. There are irreversible photochromic pigments made for some specific applications. Other photochromic pigments are reversible that are important type for textile and fashion design. According to the photochromism, the photochromic process may be categorised into several groups including triplet [1], heterolytic cleavage [2,3], homolytic cleavage [4,5], trans-cis isomeration [6,7], photochromism based on tautomerism [4,5], and photodimerisation [8]. An example of working principle of photochromic pigments is shown in (Figure 1).
