How do you calculate resultant yarn count?

Contents

Another method is by calculating the weights of equal lengths of each of the threads (Ignoring the contractions that take place as a result of twisting). Find out the resulted count when one end of the 20s; two ends of 30s; three ends of 40s are twisted together?

How yarn count is measured?

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”.

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 NM count in yarn?

Nm ( Number Metric ) count means Number metres of a yarn in 1 gram weight of yarn so for example if 1 gram of yarn has 3 meters length, Nm count would be Nm 3 , if 1 gram has 7.5 meters on length Nm count would Nm 7.5 hence Nm 3 is heavier than Nm 7.5 .

How is denier count calculated?

You can, however, calculate the deniers of a sample from its standard density, measured in grams per cubic centimeter. Divide the result by 4 x 10^-6, a constant conversion factor: 0.004972 / (4 x 10^-6) = 1,243. This is the yarn’s density in deniers.

How do you calculate CSP of yarn?

C.S.P is the product of English count and strength of yarn in pound. i.e. C.S.P = Strength of yarn in pound x Count in English system. Again, English count is the no. of hanks in 840 yards length per 1 pound weight of yarn.

How do you calculate yarn for a CV?

The formula is CV% of doubling = CV% of single / √n where n = no. of doublings 1.8 = CV% of single / √6 CV% of singles = 4.41% Ana i.e. CV% of comber sliver is 4.41%. 17. Two roving having 7.8 CV% are fed in to the ring frame making yarns and ring frame adds CV% 4.8 then what will be the final yarn CV%.

What is 60s yarn?

Cotton 60-60

The higher the number or count, the lighter or finer the yarn. Cotton 60-60 is ideal for piecing complicated blocks. This is very soft fabric in all the types. … So, we can say it is the lightest and the most expensive type of fabric. It is cost effective, light weight fabric.

What does 60×60 thread count mean?

A typical shirt is 60 x 60 thread count, or 120 thread count. This doesn’t mean the quality is bad by any means, it just means that there are less threads per square inch. The 60 x 60 means there are 60 threads going horizontally and 60 threads going vertically to form a solid weave.

What does S stand for in yarn count?

The S number often is used in conjunction with the word “super” which originally meant the best wool, (called choice wool in the United States) As now used Super means pure new wool and can also be used for fabrics made from wool blended with rare fiber (such as mohair, cashmere wool and alpaca), and also with silk.

What is count in cotton yarn?

In Metric cotton count system, yarn count is defined as the number of hanks of 1000 m per 1 kilogram of that yarn. For example, yarn count 30 Nm means that there are 30 hanks of 1000 m per 1 kilogram (kg) of that 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.

What is NM count?

An indirect yarn count system. The length of yarn in meters of one gram of yarn or length of yarn in kilometers of one kilogram of yarn is called new metric count(Nm). … The yarn becomes finer when Nm increases. It is generally used to express the count of cotton and sometimes for flax yarn.

How do you calculate yarn count in GSM?

‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter.

Relation Among Yarn Count, Machine Gauge & Fabric GSM:

G.S.M. Count Gauge
140 30 s 24 gg
150 28 s 24 gg
160 26 s 24 gg
170 24 s 24 gg

Why sizing is necessary in cotton yarn?

On the weaving machine, the warp yarns are subjected to several types of actions i.e. cyclic strain, flexing, abrasion at various loom parts, and inter yarn friction. With sizing, the strength—abrasion resistance—of the yarn will improve and the hairiness of yarn will decrease.
