600D means that the weight of 9000 meters of this kind of silk is 600 grams, and 900D means that the weight of 9000 meters of this kind of silk is 900 Gram, 600D Oxford cloth and 900D Oxford cloth are two different specifications of Oxford cloth.
To accurately distinguish, you need to calculate, D=9000*weight (gram)/length (meter). From the appearance, the larger the D number, the thicker the silk and the thicker the finished fabric. On the contrary, The finer, the thinner. The warp and weft yarns of the 600D Oxford fabric are made of polyester DTY300D yarn, which is interwoven with a thick-point changing permeable tissue on a nozzle loom.
After the textile fabric has been relaxed, refined, pre-shaped, alkali reduced, and softened and set, the back of the fabric is passed through a rubber-plastic polyester layer. It has fine texture, mild gloss, and good waterproof and fire resistance. 600D Oxford cloth is actually divided into various specifications and models, generally referring to 600D*600D Oxford cloth, and 600D Oxford cloth 5×5, which represents 500*500D, and 600D Oxford cloth 6*3, which represents 600*300D.
The lower the D number, the lower the density of the cloth, the smaller the gram weight, and the worse the pulling force. , of course the price will be lower. The fabrics generally used to make schoolbags are basically 600D*300D (6*3), and 500D*300D (5*3).
