The quality of cashmere can differ with fineness, length and color being the key factors. A yarn composed of long fibres achieves the softest feel as fewer ends are loose. Items made with long fine fibers pill less and maintain their shape better than items made with shorter hair.
Color also impacts the quality of cashmere; naturally white hair is more desirable because it doesn’t require as much processing to dye different colors.
The resulted product is softer, displaying a more lustrous finishing as it facilitates light reflection.
Cashmere should feel soft and not scratchy against your skin. The better-quality cashmere is soft, but not overly soft to touch – it softens over time. Some companies increase the softness by treating the cashmere with chemical additives and softeners or by over washing it. This reduces the life of the cashmere garment, so beware of cashmere that feels unbelievably soft.
