The count is the standard of yarn thickness. The higher the yarn count, the finer the yarn, and the thinner the cloth, the softer and more comfortable it is. But the high count of cloth requires high quality of raw materials and high requirements for yarn mills and textile weaving mills, so the cost of cloth is high.
What are yarn counts?
Heddels explains (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.
How yarn count affect the cost of fabric?
The Yarn cost will depend on the count of the yarn — finer the yarn, more expensive it will be. … It is used for coarser yarn count below 20s. The cost of man-made spun yarns will depend on the fineness — finer the yarn, more expensive it is. Number of fine filaments used in making the yarn will also affect the cost.
What does yarn count mean in retail?
Using ECC, the yarn count is the weight of set length of yarn, with a higher number being the finer count. … As an example, 30/1 ECC is 30 lengths of 840 yards, which is a total length of 25,200 yards (approx 8,150 metres) which weighs one pound (approx 445 grams).
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.
How is yarn measured?
Yarn thickness is measured using something called WPI, which stands for Wraps Per Inch. The idea is you wrap your yarn around a gap measuring 1 inch, and count how many strands you can fit in.
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.
How is yarn cost calculated?
Method 3: Conversion cost is assumed as Rs 1.60 to Rs 2.00 per count per kilogram of yarn for carded yarn and Rs 1.90 to Rs 2.30 per count per kilogram of yarn for combed yarns by the mills depending upon the various factors. The cost varies from mills to mills since it is decided by the management.
How is fabric cost calculated?
- EPI = 100.
- PPI = 80.
- Warp count = 40 s cotton.
- Weft count = 40 s cotton.
- Fabric width=120 inches.
- Warp crimp = 11 ℅
- Weft crimp = 4℅
- Waste percentage= 3℅
How do you calculate fabric?
Figure out how much fabric you need with this formula:
- Width of fabric divided by width of one piece equals the number of pieces that fit into width (rounded down to the whole number).
- Total number of pieces divided by number of pieces that fit into width equals number of rows you need.
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.
Which are the factors used in yarn count?
This agrees with the Uster ranking of fiber properties. 30 Among the 19 factors considered, the five most influential factors were yarn twist, fiber length, yarn count, length uniformity, and fiber strength. These five factors accounted for 63.4% of the yarn strength prediction (Fig. …
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%.
