ASTM D3887

针织物密度测试方法

12. Test Method----Fabric Count

测试方法---织物密度

12.1 Scope—This test method is applicable to knitted fabrics of all types, such as warp knits,卸妆巾 weft knits, flat

bed knits, and so 对方的英文 forth.

范围---本测试方法适用于各类针织织物，如经编、纬编等等。

12.2 Summary of Test Method—The number of wales a桓仁旅游 nd cours per unit distance are determined using suitable

magnifying and counting devices.

方法的概述---用放大镜等仪器来测定织物经向或纬向单位长度的横列数或纵行数。

12.3 Significance and U—This test method is considered satisfactory for acceptance testing of commercial

shipments becau of prior extensive u. In ca of disagreement arising from differences in values reported

by the purchar and the ller when using this test method for acceptance testing, the statistical bias, if

any, between the laboratory of the purcha飘的经典语录 r and the laboratory of the ller should be determined with each

comparison being bad on testing specimens randomly drawn from one sampling unit of material of the type being

evaluated.

意义和用法---本方法用于商业出货验收测试，如果买方和卖方对报告结果有争议时，如数值偏差等情况时，买方和卖

方的测试室应评估样品是否在同一批织物取样。

12.4 Apparatus—U any suitable magnifying and counting device (such as pick glass, rule and pointer, microfilm

reader, or projection equipment).

仪器设备---任何放大或计算设备(如放大镜、直尺、小针、显微镜等78年属相 )。

12.5 Sampling:

取样

12.5.1 Take a lot sample as directed in Section 6 or as agreed upon between the purchar and the ller.

按第6部分或买方与卖方协议取得样品。

12.5.2 From the lot sample of rolls or pieces, cut one laboratory sample from each roll or piece the full width

of tubular or open-width knit fabric, and at least 2 m (2 yd) in length.

从一卷或一批中取得一块整幅宽至少2米长的样品。

12.6 Conditioning—Condition specimens as directed in Section 7.

调湿---按第7部分将样品放置于恒温恒湿室至恒重(每隔2小时称重，当前后两次重量偏差不超过0.1%时为恒重)。

12.7 Procedure:

步骤

12.7.1 Unless otherwi specified in a prior agreement between the purchar and the ller, make no count clor

to a lvage than one-tenth of the width of the fabric, or within 0.5 m (0.5 yd) of the end of the roll or piece.

在幅宽的1/10外和一匹或一卷末端0.5米(0.5码)外测定横列数和纵行数。

12.7.2 Unless otherwi specified, count the wales and cours on the face side of the fabric.

除非有特别规定，通常测定织物的正面。

12.7.3 For fabrics containing 10 loops per linear cm (25 loops per linear in.) or more, determine the number

of wale loops and cour loops per 2.5 cm (1 in.) by counting the number in a space not less than 5 cm (2 in.)

at five different places in the piece, equally spaced both across the width and throughout the length to the

nearest whole number of loops.

如织物每厘米含10个线圈( 每英寸含25个线圈)或以上的，则在每批5个不同位置测定至少5厘米(2英寸)的纵行数

和横列数。

12.7.4 For fabrics containing less than 10 loops per 1 cm (25 loops per 1 in.), make the count over a 10 cm (4

in.) width and repeat in at least five randomly designated places across the width and throughout the length

to the nearest whole number of loops.

如织物tct报告 每厘米含少于10个线圈(每英寸含少于25个线圈)的，则在每批5个不同位置测定至少10厘米(4英寸)内的纵

行数或横列数。

纵行数或横列数/in 25或以上 25以下

最小测定距离 2英寸(5厘米) 4英寸(10厘米)

测定次数(位置) 5 5

针织物密度测试方法

12.7.5 In fancy knits where one or more yarns do not appear at regular, short intervals, make count measurements 婴儿疝气图片男孩

over at least one full pattern repeat of each design component to the nearest whole number of loops.

如织物有花型或图案，则测定织物花型的整个循环长度的纵行数或横列数。

12.8 Calculation---Calculate the average number of wales and cours per 2.5 cm (1 in.) to the nearest 0.1 wale

or cour.

计算---计算5个不同位置每2.5厘米(1英寸)的横列数或纵行数的平均值，精确到0.1个纵行数或横列数。

12.9 Report:

报告

12.9.1 State that the specimens were tested as directed in Specification D 3887. Describe the material or product

sampled and the method of sampling ud.

注明本测试是按照ASTM D 3887方法，描述所用物料和方法。

12.9.2 Report the following information:

报告以下内容﹕

12.9.2.1 Average number of wales and cours per 2.5 cm (or per 1 in.) stating the wale count first.

每2.5厘米(1英寸)的横列数和纵行数的平均值，先横列数(wales/in)再纵行数(cours/in)。

12.9.2.2 Size of the pattern repeat, size of each design component in the pattern, and the total yarns in each

measured component for fabrics having fancy knits.

列出花型图案循环的尺寸大小。

12.9.2.3 Temperature and relative humidity conditions during testing. For example, standard atmosphere for

testing textiles, ambient conditions, and the like.

12.10 Precision and Bias:

精度和偏差

12.10.1 Precision---The precision of this test method for counting wales and cours in knitted fabrics is being

established

精度---本方法已建立了针织物横密和纵密的精确度。

12.10.2 Bias---This test method for counting wales and cours in knitted fabrics has no known bias and is ud

as a referee method.
