求翻译：上次4号产品我们本来多备了布料，但由于不合格率太高，导致交货不够数量，4号产品确实生产成本太高，如果还按原来的价格，我们要亏本了。是什么意思？

We had the last 4 products prepared more fabric, but because of the failure rate is too high, resulting in the number of delivery is not enough, 4 products that production costs are too high, according to the original price if it is, we lost money.

The previous 4 products we have prepared the cotton material originally, but because the fraction defective too is high, causes the delivery insufficient quantity, 4 product truly production cost too is high, if also presses the original price, we had to lose money.

Last 4th product, we would have a cloth, but because of the failure rate is too high, resulting in insufficient number of delivery, 4th number product production costs are too high, if the original price, we lost money.
