What kind of thread should I use for a garment that is to be washed and bleached, for example by enzymes or acid?
We recommend our Astra Rugged Heavy Duty Polyester Thread for denim. It is a polyester thread that is specially designed for high performance sewing. It is manufactured using imported high tenacity stabilized polyester fibre. It has many outstanding properties which make it superior to other spun polyester threads: it is resistant to perspiration and chemical attack, it is suitable for tropical conditions, and it provides high colour fastness in all normal conditions of use.
