To understand about cashmere quality, get to know the cashmere fiber
Basically, the longer and finer the fiber, the higher the cashmere quality. Long fibers remain twisted into the yarn, thus reducing pilling and stretching. Garments made with high quality cashmere fibers will keep their luster and shape, even after many years of use.
There are three grades of quality for cashmere:
Grade A is the finest quality cashmere, with an average fiber length of 34 - 40 mm and a diameter of 14 - 15.5 microns. Henderson Cashmere uses only grade A cashmere fiber.
By comparison, the finest wool fibre has a diameter of approximately 20 microns and a human hair averages a width of 60 microns or more.
Grades B and C have a shorter fiber length and wider diameter. These grades are commonly used by many cashmere brands and are more prone to pilling, stretching and wear.
Extraordinary properties
Although extremely fine, cashmere fibres are hollow, providing a natural, light-weight insulation. During colder weather, body heat is absorbed into these tiny air pockets to keep you warm and cozy.
Cashmere fibre has a ‘hygroscopic’ effect that draws moisture away from the skin. This creates a cooling effect in warmer months while also helping to keep you warm in winter.
These extraordinary properties make it possible for cashmere to be comfortably worn all year around.
