What is the yarn count of fabric? ›

Lesson Summary. In textiles, yarn count is a number that represents the diameter or fineness of a yarn, either in terms of weight by length or length by weight. The direct system measures the weight of a consistent length of yarn, with a higher yarn count indicating a heavier and coarser yarn.

As an example a 6Nm yarn weight will have a length of 600m per 100g, and a 2nm yarn will have a length of 200m per 100g etc. Finished yarn is then written down as two numbers, the first number being the number of singles in the plied yarn and the second number being the weight of the singles used in that plied yarn.

The most direct measure is to express the value in terms of the grams (of yarn) per km, known as the tex of a yarn. The bigger the number, the thicker the yarn. The smaller the number, the finer the yarn. In general terms, fine count yarns range from 20 tex, or 20 g/ km, to less than 10 tex or 10 g/km.

A good base yarn count number starts somewhere in the 100s, but if you are seeking a maximum standard, yarn count can move up further, towards 200. But, any yarn count above 140 should be adequately soft to the touch.

It represents the weight in grams of 1000 meters of yarn. For example, 1 Tex indicates that there is 1 gram of yarn per 1000 meters of that yarn. 20 Tex: 1000 meters of length and 20 grams of weight.

Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine.

Here is how to calculate how much yarn you will need

Measure and weigh the swatch. You can now calculate the grams per cm2/in2 by multiplying the width of the swatch by the height of the swatch to get the area then dividing the weight by the area.

Fabric count term is not exist . Yarn count defines the thickness or fineness of the yarn. Like in English count, number of 840 yards in one pound, or Tex, Grams per 1000 meter. Thread count is the number of ends per inch or picks per inch, both of which will determine the weight of the fabric.

The term "count" refers to the number of yarns used (weft yarn count and warp yarn count), and generally refers to how many weft and warp yarns are used in one inch of fabric. The number, or yarn count, indicates the thickness and smoothness of the yarn.

Sometimes, yarn counts are mistaken for thread counts. But, there is a clear distinction between them. While thread count gives you information on how many threads are packed into one square inch of the fabric, yarn counts aim to find the coarseness of the yarn.

How to calculate fabric count? ›

Fabric count, also known as thread count, refers to the number of warp and weft threads per square inch in a woven fabric. It is a critical metric used to evaluate the density of the fabric and has a direct correlation with its overall quality.

It is the method used to describe the density (thickness) of the yarn and is traditionally given in “cotton count” e.g. 16's, 30's, 40's. In this system the lower the count, the thicker the yarn, so a 16's yarn will be thicker than a 40's yarn.

It is widely used in the metric system and is calculated by the formula: Tex = (Weight of Yarn in Grams) / (Length of Yarn in Kilometers). - Denier: Denier measures the weight (in grams) of a 9,000-meter length of yarn. It is commonly used for synthetic fibers such as polyester and nylon.

Yarn Count Unit

It refers to that how many 840 yards of the yarn's length, which is what the number of yarns counts with a pound yarn under the public moisture regain. The thicker the yarn, the smaller the S value of the yarn, for example, the 40S yarn is thinner than the 20S yarn.
