Q2: Are Marathon threads colourfast?
A: Polyester threads are extremely colourfast no matter what detergents you use (refer to Q3). As for Viscose Rayon Threads, as long as garments are washed using a mild detergent containing no additives, Marathon threads will remain colourfast for the life of the garment. Many people prefer to use Viscose Rayons as rayon threads come in a rich variety of colours (397 colours) and especially because of their velvet-like silky lustre. Please refer to the washing instruction listed in the colour chart.
Q3: Which thread should I choose if garments are to be exposed to industrial laundering?
A: You will need to use Polyester threads when the embroidered garments are to be washed in chlorine bleach or exposed to harsh industrial laundering (eg hospital uniforms, military uniforms etc)
