LONDON – Polyester fabrics and yarns that can degrade into water and CO2 under specific compostable conditions and that can be dyed at lower-than-normal temperatures are on display here at the on-going Textile Exchange conference in the UK.
It’s claimed that by using a combination of two very specific types of monomers in the dope solution before the polyester filaments are extruded, the hydrophobicity of the polyester is altered so that microorganisms can break down the fibre when fabrics are composted through simple hydrolysis.
