Silk is an animal textile made from the fibres of the cocoon of the Chinese silkworm which is spun into a smooth fabric prized for its softness. There are two main types of the silk: mulberry silk produced by the Bombyx Mori and wild silk such as Tussah silk. Silkworm larvae produce the first type if cultivated in habitats with fresh mulberry leaves for consumption while Tussah silk is produced by silkworms feeding purely on oak leaves. Around four-fifths of the worlds silk production consists of cultivated silk
Textiles receive a range of treatments before they reach the end-user. From formaldehyde finishes (to improve crease-resistance) to biocidic finishes and from flame retardants to dyeing of many types of fabric the possibilities are almost endless. However many of these finishes may also have detrimental effects on the end user. A number of disperse acid and reactive dyes (for example) have been shown to be allergenic to sensitive individuals.24 Further to this specific dyes within this group have also been shown to induce purpuric contact dermatitis.
Since the 1990s with advances in technologies such as permanent press process finishing agents have been used to strengthen fabrics and make them wrinkle free.22 More recently nanomaterials research has led to additional advancements with companies such as Nano-Tex and NanoHorizons developing permanent treatments based on metallic nanoparticles for making textiles more resistant to things such as water stains wrinkles and pathogens such as bacteria and fungi.
