Before understanding the difference among woolen cashmere yarn, semi-worsted one and worsted one, we need to know what cashmere yarn is and how it’s been made.

Cashmere yarn is made from raw cashmere material, and there are a series of production processes, namely, blending, carding, spinning, winding, doubling, twisting and others.
According to the different craft and thickness, cashmere yarn can be divided into three different kinds: woolen cashmere yarn, semi-worsted one and worsted one. Woolen and worsted cashmere yarns are more common and semi-worsted is also popular. So what’s the difference among woolen, semi-worsted, worsted cashmere yarn?
Relatively woolen cashmere yarn is thicker than semi-worsted and worsted yarn and it has low count, generally from NM2/14 to NM2/32. Semi-worsted cashmere yarn is thinner than woolen one and it has relatively high count, generally from NM2/24 to NM2/60. Worsted cashmere yarn is also thinner and stronger in twist than woolen yarn and its count is higher, generally from NM2/28 to NM2/120.
Semi-worsted and worsted cashmere yarns are mainly suitable for spring/summer knitting, like t-shirts, underwear, cardigans and else ultra-thin dresses, while woolen cashmere yarn is softer and more fluffy suitable for fall/winter use, like sweaters, poncho, scarves, gloves and so on.
