The direct system or fixed length system is the yarn count system where the count of a yarn is calculated by measuring the mass of a fixed / definite length. … So, higher the count, coarser the yarn. In direct count system, the length of yarn is fixed and the mass of yarn varies according to its fineness.
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. … The indirect system uses the formula: N = (L/w) / (W/l).
What is direct count system?
In a direct yarn counting system, the yarn number or count is the weight of a unit length of yarn. This means the higher the yarn count number, the heavier or thicker the yarn. It is fixed length system. … Denier: In the direct Denier system, the yarn count number indicates “the weight in grams of 9000 meters of yarn”.
What is meant by yarn count?
Yarn count refers to the thickness of a yarn and is determined by its mass per unit length. It is usually measured by the number of grams per one kilometer of yarn, a unit of measure called “Tex”. … In this system, the larger the number the finer the yarn and vice versa.
What is a good yarn count?
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.
Is Tex direct count?
For example, yarn count 30 Tex means that there are 30 grams of yarn per 1000 m or 1 km of that yarn (mass per length) .
Direct yarn count system.
|Count System Name||Unit of length||Unit of mass|
|Tex||1000 m||No. of grams|
|Denier||9000 m||No. of grams|
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.
What is cotton yarn count?
Also referred to as Ne or Number English. It is the number of times the length of one pound of yarn can be divided by 840. … Therefore, a 6/1 Ne yarn would have 5,040 yards in one pound of yarn.
How do you read yarn count?
As a general rule of thumb the finer the yarn the higher the count number (see below for why) and metric counts usually are expressed with the count first then the ends – 30/2nm whereas cotton and worsted counts tend to have the ends first then the count – 4/8cc or 3/9wc.
Which is the simplest type of yarn?
Simple yarns are characterized by uniform size and regular surface. They can be broadly divided into single, ply, cord, and rope yarns. 1. Single yarn is the simplest type of yarn.
Why is yarn count important?
Importance of Yarn Count
The yarn count can tell you a lot about a yarn’s durability, strength, and comfort. It’s an important number, and that means it’s one that you don’t want to estimate. … In its most basic sense, the yarn count represents either the mass per unit length or length per unit mass of the spun yarn.
What is denier count?
Denier is a unit of measurement used to determine the fiber thickness of individual threads or filaments used in the creation of textiles and fabrics. Fabrics with a high denier count tend to be thick, sturdy, and durable. Fabrics with a low denier count tend to be sheer, soft, and silky.
What is worsted count?
The number of hanks ( skeins) having the length of 560 yards in one pound of yarn is called worsted count. It is used to express the fineness of worsted yarn. The fineness of yarn increases when yarn count increases in this system.
What is 40s yarn?
Cotton 40-40 is the heaviest. 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.
What does 40s cotton mean?
In cotton count (indirect yarn numbering) system, higher the count of yarn is finer the yarn. 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 warp yarn count?
The number of warp yarns per one inch or centimeter of fabric. This is also called sley, warp end count, ends per inch, or ends per centimeter.
