2, fabric number: reference number of wool fiber diameter micrometer, the smaller the number, the better. Kiton fabric starting from the 14 microns, top fabrics up to 11 points a few microns.
3, elastic fabric: the fabric itself has a lot of good elasticity and reduction of, rub together can restore into flat and wrinkle-free. This test is best used on the leather, elastic is leather.
4, fabric textures: fabric feels good are very delicate, feels warm and comfortable not mill hands hang when using the vertical sense of nature. Nylon/polyester fabric to clear lines, density lines obviously, small nylon fabric also has a tear effect.
5, surface gloss: good exposure in the light fabric luggage would have contrasted with bright, soft light, gloss of different fabrics are different, thick clear nylon fabric density, so shine brighter than any other clothing or fabric to some; leather itself is highly reflective, so high gloss.
