What is Yarn Count?

A count is a numerical value expressing the fineness or coarseness of yarn and also indicating the relationship between length and weight. The concept of yarn count, which specifies a certain ratio of length to weight, has also been introduced. It is also the mass per unit length or the length per unit mass.

Types of Yarn Count Measurement:

There two types of yarn count. They are:

  1. Direct count system
  2. Indirect count system

1. Direct Count System:

In direct count system, the weight of a fixed length of yarn is determined. The weight per unit length is the yarn count. The following formula is used to calculate the yarn count:

Standard table for direct numbering system

Number systemUnit of length (l)Unit of weight (w)
Tex system (tex)1000 meters1 Grams
Denier (D)9000 meters1 Grams
DeciText (dtex)10,000 meters1 Grams
Millitex (mtex)10001 Milligrams
Kilotex (ktex)1000 meters1 Kilograms
Jute Count/linen/hemp14,400 yds.1 Pounds

2. Indirect Count System:

In indirect count system, the length of a fixed weight of yarn is measured. The length per unit weight is the yarn count. The following formula is used to calculate the yarn count:

Standard table for indirect numbering system:

Number systemUnit of length (l)Unit of weight (w)
English cotton count(Ne)840 yds.1 pound
Metric count (Nm)1000 meters1 kg
French or continental count1000 meters0.5 kg
Woolen count (YSW)256 yds.1 pound
Woolen count (Dewsbury)1 yds.1 ounce
Worsted count560 yds.1 pound
Linen count300 yds.1 pound

Some Important Conversion:

1 yds=0.9144 meter1 meter= 1.0936 yds.
I meter= 39.37 inch1 cm= 0.3937 inch
1 gm.= 0.0353 oz1 oz= 28.350 gm.
1 pound= 453.6 gm.1 kg= 2.2046 pound
1 inch= 2.54 cm1 pound=0.4536 kg
1 pond=16 oz1 pound= 7000 grain

Some shortcut conversion formula:

What is Resultant Count?

Resultant count is the number of yarns that are twisted or folded. Two or more threads are folded or twisted into a single strand form when they are folded or twisted. Two or more of these already twisted yarns are folded together to form a “folded” yarn. For special strength and solid effects, yarns such as fishnet yarns, cords, harness cords, special sewing threads, shoe threads, and so on are cabled.

In case of direct count system, resultant count is calculate by using following formula

N= N1+N2+N3………………….

In case of indirect count system, resultant count is calculate by using following formula.

Exercise:

Problem-1: If the weight of 200 meter cotton yarn is 4.724 grams, what will be its count in Ne, Tex and Denier?

Problem-2:  If a skein of viscose filament yarn weighs 1.70 g and its length is 70 m, what is the denier of that yarn?

Problem-3:  If 150 yards of jute yarn weighs 3 ounces, what is its count?

Problem-4: If the weight of 1 lea cotton yarn is 30 grains, what will be the count?

Problem-5: if the weight of 1 lea cotton yarn is 2.16 gm, what will be its count in Ne, tex, denier and Metric count?

Problem-6: what length of yarn is contained in 1.2 kg of yarn of Ne 30?

Problem-7: What is the resultant count of 40/3 jute yarn?

Problem-8: If 3 ply yarn is prepared with 30, 25 and 20 cotton yarn, what will be the yarn count?

Problem-9: What is the resultant count of 30/2 cotton yarn?

Problem-10: If one single yarn count is 60 and two-ply count is 35, what is the other single yarn count?
