Determining the quality of the 100% cashmere scarf
The touch test
The cashmere scarf should not cause any scratchiness or itchiness. The fabric needs to be soft on touch. The cashmere scarf which is soft but not too much is the one with good quality as cashmere softens further with time. Some companies would endeavor to increase the softness of the fabric using softeners or by over-washing it. Such cashmere scarves do not last long. You should avoid cashmere scarf that is overly soft to touch.
The pilling test
When you rub your hands on any cashmere scarf, little balls should not be formed immediately. If they do, it implies that the garment has used a significant amount of shorter hairs, compromising the quality. Cashmere scarf does pill over time but should not when they are new.
