    问:纱支数怎么计算


    发布时间:2014-08-25 09:02:00 点击:

    答:目前所讲的纱支数大都是指“英制支数”,用英文字“S”表示。它的定义是:在公定回潮率下,重一磅的纱线,它的长度有几个 840 码,就称为几支纱线。纱线越粗,S值就越小,纱线越细,则“S”值越大。即40S/1要比20S/1的纱支幼细。这样,在同种结构的针织布中,纱支越幼细,它的克重(g/m2)就越轻。如 32S/1平纹布成品克重在 135-145G/M2之间,而20S/1平纹布的成品克重在180-190G/M2。

    A: Currently yarn count spoken mostly means "English count", with the English word "S" indicates. It is defined as: Under moisture regain, heavy pound of yarn, it has a few 840 yards in length, it is called a few pieces of yarn. Thicker yarn, S value, the smaller, finer the yarn, the "S" value is greater. That yarn 40S / 1 than 20S / 1 of Fine. Thus, in the same kind of structure of knitted fabric, yarn more finely, its weight (g / m2), the more light. As 32S / 1 plain weave fabric finished g lies between 135-145G / M2, and finished grams 20S / 1 plain weave fabric of lies 180-190G / M2.
