求翻译：我们需要10块标准布样，是因为我们的布料在生产过程中，印染厂需要经常核对标准色，并且布样因为频繁使用，可能会慢慢变色。因此我们寄给布料供应商（印染厂）的布样至少要2套，以便他们可以密封保存至少一份正确的标准样在手中备用。同时我们也需要寄给BDU工厂。是什么意思？

We need 10 standard cloth -like , because we are in the production process of the fabric , dyeing requires frequent check standard color and fabric swatches because of the frequent use may slowly change color .

We need 10 pieces of standard fabric sample, because our fabrics in the production process, dye houses need to frequently check the standard color, and fabric swatches for frequent use, may slowly change colour. So we send the fabric vendor (printing and dyeing mill) sample should be at least 2 sets
