By applying actual average production rate in various counts, wages and salaries cost per kilogram of yarn is estimated. Power cost per kilogram is worked out by multiplying units required per kilogram of yarn (UKG) and average cost per unit.
What is the rate of yarn?
The price of Cotton Yarn products is between ₹115 – ₹155 per Kg during Jan ’21 – Dec ’21.
How do you calculate Tm of yarn?
- Low TM = softer yarn.
- High TM = stiffer yarn.
- Twist (TPI) = TM x SQRT NeC, or.
- Twist (TPM) = TM / SQRT Tex.
- % TC = Length Before Twisting (A) – Length After Twisting (B) x 100%
- Length Before Twisting (A)
- 1 – % Contraction.
How do you calculate yarn for a CV?
The Coefficient of Variation (CV) is the standard Deviation (SD) expressed as a percentage of the mean CV % = (SD ÷ mean) x 100 • Each process in a spinning mill contributes a part to the evenness.
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. By this, we can compare the fabrics in the unit area which are heavier and which is lighter.
Relation Among Yarn Count, Machine Gauge & Fabric GSM:
|160||26 s||24 gg|
|170||24 s||24 gg|
|180||24 s||24 gg|
|190||22 s||24 gg|
What is the price of 1kg wool?
Fine Wool Monthly Price – Indian Rupee per Kilogram
How does TM calculate TPI?
- Turns per inch t.p.i = 0.0254 * t.p.m.
- Turns per meter t.p.m = 39.37 * t.p.i.
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 actual draft calculated?
Actual draft = Weight per yardfed/wt. per yard delivered Mechanical draft (is calculated from gearing) is determined, by use of the actual draft (required) and waste%. So, Mechanical draft is always less than actual draft.
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.
What is IPI in yarn?
IPI stands for Imperfection Index of Yarns. Imperfections is the description for thin, thick places and neps in 1000m of yarn. Evenness Tester is required to calculate the IPI of yarns with the results of different yarn evenness parameters. … The carding process has a major impact on yarn imperfection.
What is unevenness in yarn?
unevenness is a measure of variation in weight per unit length of the yarn or the variation in thickness of the yarn. Uster measures the yarn unevenness by a capacitive method. … As a result, the yarn produced has improved evenness.
What is GSM in yarn?
GSM stands grams per square meter which is unit of measurement of a fabric, whereas, Count is the measure of the thickness of the yarn in the units of grams per one kilometer, which is used in textiles. GSM is one of the main parameters in knitting fabric and it is one of the main specification.
Why is yarn count important?
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.
How is PPI and EPI calculated?
It is found out by counting the number of threads in the warp and weft in a square inch of the fabric. Fabric construction is written as “136 x 96”, which means that the fabric has 136 Ends per inch (EPI) and 96 Picks per inch (PPI). Alternatively this can be written as EPI x PPI = 136 x 96.
