In an indirect yarn counting system, the yarn number or count is the number of “units of length” per “unit of weight” of yarn. This means the higher the yarn count number, the finer or thinner the yarn. It is based on the fixed weight system. This system is generally used for cotton, woolen, worsted and linen yarn.

## What is the difference between direct and indirect yarn count methods?

The direct system measures the weight of a consistent length of yarn, with a higher yarn count indicating a heavier and coarser yarn. The indirect system measures the length of a consistent weight of yarn, with a higher yarn count indicating a finer yarn.

## What is S in yarn count?

Yarn Count Unit

S is the British count. 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.

## What is Tex and denier?

Tex is a direct measure of linear density. den (denier): Grams per 9,000 metres of yarn. Den is a direct measure of linear density. dtex (deci-tex): Grams per 10,000 metres of yarn. Dtex is a direct measure of linear density.

## How do I find the yarn number?

The yarn number is the length in yards of one pound of the yarn, divided by 1600. Symbol N_{ar}. This is the same as the weight in ounces of 100 yards. So one pound of number 1 run yarn is 1600 yards long, one pound of number 2 run yarn is 3200 yards long, and so on.

## What does NM mean in yarn count?

The Nm stands for ‘normal metric’ – which is based on 1 000 metres of yarn per kilogram. The first number refers to the number of strands plied together. The second number tells you how many hanks of 1 000 metre lengths of a single ply of the yarn would weigh one kilogram.

## What do you mean by 30 NE?

For example, yarn count 30 N_{e} means that there are 30 hanks (each hank consisting of 840 yards of yarn) per 1 lb or 1 pound of that yarn (length per mass) . In other words, if a yarn has a count of 30 N_{e} , it means that 30 hanks (of 840 yards) of that yarn will weigh 1 pound.

## What is 40s yarn count?

Cotton Count is defined as the number of 840 yards length of yarns in one pound. It means that the number of yarns of 840 yards length required weighing one pound. … For example, a 40’s yarn is two times finer than a 20’s yarn. The yarn count of a regular T-shirt made of single jersey fall in between 20 to 40.

## What is 40s count?

The weight of 40s count yarn is 1.5 times that of a yarn of 60s count. This is cheaper than both cotton 60-60 and cotton 60-40. Durability of clothes is a major issue and cotton 40-40 is the most durable fabric among all. 40 weight cotton thread is ideal for machine quilting where you want the quilting to be prominent.

## What does 120s wool mean?

Day-in, day-out wear: Super 110s – Super 120s

This means that the quality yarns can be twisted tightly, making the fabric more wrinkle-resistant and durable.

## How is Tex calculated?

Thread count in tex

The tex number indicates how many grams a sewing thread of 1000 m length weighs. The unit is expressed in tex. Example: 17 tex means: 1000 m of the yarn weighs 17 g. The smaller the tex number, the finer the thread; the larger the tex number, the thicker the thread.

## What is DTEX in yarn?

Decitex (dtex) is a metric unit, also mainly used for continuous filament yarn, defined as the mass in gram per 10,000 m. For instance, 440 dtex means 440 g per 10,000 m fiber/yarn; 220 dtex, 220 g per 10,000 m fiber/yarn; 1670 dtex, 1670 g per 10,000 m.

## What is Lea in textile?

The number of hanks of 300 yards in a pound is called linen count (lea). It is specially used to express the fineness of flax (linen) yarn. Yarn becomes finer when the count increases in this system. If the weight of yarn is w grams, and the length of yarn is L meters then the lea count of yarn is obtained as follows.

## How is yarn length measured?

– Hold your skein stretched out between your hands (but not too tightly), and hold a tape measure along that length. That gives you the length of half your skein. Take the number of strands, multiply it by 2, and multiply it by the measurement from your tape measure.

## How do you measure yarn length?

Multiply the number of yards or meters in a full skein (on the yarn’s label) by the weight of the partial skein (use a scale to measure this). Take that number and divide it by the weight of the full skein (on the yarn’s label). The resulting number is about how many yards or meters is in the partial skein.

## How is yarn IPI calculated?

The imperfection index (IPI) is the sum of yarn thin places/ km (-50%), thick places/km (+50%) and neps/km (+200%) per kilometer of tested yarn for ring spun yarn [2, 59] .
