Cashmere thread is a kind of knitting thread for rod needles made from cashmere. The raw material of cashmere yarn is cashmere, while the practical range of wool and wool is very wide, which can be any raw material, including cotton, wool, acrylic or mohair.

Cashmere is a layer of fine wool from cashmere goats (also known as Cashmere goats), with a diameter of 14-17um and a length of 30-45mm. Cashmere fiber is composed of cortex layer and scale layer, and its cross section is elliptical cylindrical. One cashmere goat produces only about 75g of non-wool per year, and five cashmere goats produce only enough wool to weave an ordinary cashmere sweater.
