40S/2 Anti-Yellowing Spun Polyester Sewing Thread That Keeps Whites White

MH 40S/2 anti-yellowing spun polyester sewing thread is a 100% spun polyester two-ply sewing thread finished to resist phenolic yellowing, so white and pale-coloured fabrics stay white through storage, heat setting and finishing.

The thread is spun from polyester staple fibre in a 40S/2 ticket, giving a soft, matte hand and a smooth run on high-speed sewing machines. Its anti-phenolic yellowing performance reaches test grade 4-5, which prevents the grey or yellow cast that ordinary threads can develop on light fabrics.

MH supplies the thread for sewing white and light-coloured textiles such as shirts, hotel bedsheets and white towels, where keeping the original white shade is essential.
