As we known as bobbing, a fabric will pill when it has rubbed against itself. Pilling usually forms on the arms, elbows, sleeves, and stomach of a sweat or other clothing pieces. The shorter the fibers of a fabric, the more easily they get twisted up and knotted. Cashmere fabrics do pill, but it depends on the quality of the cashmere. A finer, tighter cashmere wool will pill less than the lower grades. So, using that premise, we have the pilling test. All you need to do is run your hand over the cashmere. You may notice right away that little wads of fibers are forming. That means there are shorter fibers within the fabric, which is indicative of a lower quality. All cashmere pills when met with friction over time, but only the lowest quality will pill rapidly. We pay more attention to anti-pilling during the production by selecting long cashmere fibre and alittle bit high twist for yarn spinning, and we do lab test for every lot of cashmere sweaters in order to keep the anti-pilling grade up to Grade 3.
