ISO 7211的这一部分规定了三种测定机织物每厘米线数的方法。可以使用三种方法中的任何一种,选择取决于织物的特性。但是,如果存在争议,建议采用A方法。方法A:织物解剖,适用于所有织物。这是最费力的方法,但比其他方法有更少的局限性;特别是,它是唯一一种真正适合于检查某些折叠结构和其他复杂织物的织物。方法B:计数玻璃,适用于每厘米50线以上的机织物。方法C:穿线计数器,适用于所有面料。如果每厘米的线程数较低,则可以方便地将结果表示为每分米的线程数。
注:附录中给出了使用平行线光栅和锥形线光栅的方法,以供参考。这些方法被认为不够准确,不能用作标准测试方法,但可以用于为常规测试提供粗略和现成的估计。
This part of ISO 7211 specifies three methods for the determination of the number of threads per centimetre in woven fabrics. Any of the three methods may be used, the choice depending on the character of the fabric. However, in case of dispute method A is recommended.Method A:Dissection of fabric, suitable for all fabrics. This is the most laborious method but has fewer limitations than the others; in particular, it is the only one that is really suitable for the examination of certain folded structures and other complicated weaves.Method B:Counting glass, suitable for woven fabrics with more than 50 threads per centimetre.Method C:Traversing thread counter, suitable for all fabrics.Where the number of threads per centimetre is low, it may be convenient to express the results as the number of threads per decimetre.NOTE - Methods using parallel line gratings and tapered line gratings have been given in the annex for information. These methods have not been considered accurate enough to be used as standard test methods but can be used to give rough and ready estimates for routine testing.
