||Polyester + special spinning
Glow In The Dark Embroidery Thread is a polyester thread that has been treated with a brightly glowing pigment which absorbs light and glows for several hours after being charged. It can be used for luminous knitted clothing, luminous shoes, luminous embroidery, which adds fun to your special designs. Just dress it to join party, you must be the shiniest one in the crowd. Put the glow in the dark embroidery machine thread in the sunshine for about 5-10 minutes or use your light power to "charge" it(just shine it). Then you will see something surprise in the dark place. After the light power charging, it will keep glow in the dark for over 8 hours. (The glow effect wears off.)
But pay attention to do not dry clean, iron, or place in the washer with bleach.
If a glow-in-the-dark thread is solely made from polypropylene, it will be weak and untwist easily. Our thread lines that glow in the dark are made of a special type of polyester polymer which is not easy to break and looks lighter.
