How Pashmina Is Graded: Micron Count Explained

A Pashmina shawl carries no printed number for the fineness of its fibre, yet this one invisible factor determines almost everything about how the shawl will feel, drape and age. The grading takes place long before spinning starts, on the raw fleece rather than the yarn or the shawl itself, and it is the stage of the craft buyers rarely get to see.

What Micron Count Actually Means

A micron is a unit of measurement representing one thousandth of a millimetre, and in textiles it refers to the diameter of a single fibre. Ordinary human hair ranges from fifty to one hundred microns, coarse sheep's wool is well above thirty, and genuine Ladakhi pashm sits in a much finer range, usually between twelve and sixteen microns. The difference looks minor in writing but is considerable to the touch. Because the finer fibre bends more easily against the body, it traps more still air relative to its weight, and this is what gives genuine Pashmina its soft, almost weightless warmth, distinguishing it from all heavier alternatives.

Where on the Goat the Finest Fibre Comes From

Not every strand of down from one Changthangi goat is equal: the best and softest fleece is found at the throat and under the belly, the areas most exposed to the wind, whereas the down from the sides and rear is a little coarser. From the very beginning, herders and hand dehairers divide the raw fleece, sorting it broadly by fineness and colour before it reaches a spinner. The sorted fleece ranges from the finest and palest grade, most highly valued for the lightest shawls, down to coarser mixed grades that still make good, if somewhat heavier, cloth.

How Purity Is Actually Tested

Folk tests travel further than accurate ones. The burn test and the ring test are both old habits rather than reliable science, and neither confirms micron count or purity on its own. Genuine testing is done with a microscope, measuring the actual diameter of individual fibres across a sample, or increasingly through DNA-based methods that can distinguish true pashm from cheaper goat or sheep wool blended in to cut costs. These are laboratory processes, not something a buyer can perform by touch in a shop, which is exactly why provenance and testing certificates matter more than any home trick.

What This Means When You Buy

Since the micron count is not stitched onto the label, the clues a buyer can assess are only indirect. A finely spun yarn with a small amount of natural unevenness, warmth out of proportion to the weight of the fabric, and a producer willing to state clearly where the fibre was graded all indicate that the pashm is genuine and well sorted. None of these signs replaces an honest source, however; grading happens only once, early and quietly, and everything that happens to the shawl afterwards depends on whether it was done properly.
