请教，客人要订购几种特殊原料的纱线，找到了一个纱线供应商，然后就问我需要的纱线是sized or unsized, 请问这是什么意思？该怎么回复？
具体的邮件如下，请参考：

Please advise if the yarns need to be sized or unsized and confirm we will be weaving.

We are weaving fabric that is 60’s
60X60/90X88 or
60X60/90X80

Please note for sampling we will be weaving about 100 yards based on the above constructions. We will order enough yarn for about 10,000 yards for production

路过但是也不知道，字面意思是分号或不分号
