What is yarn lea strength?
The Lea strength of yarn is one of the major properties on which the suitability of yarn for its ultimate end use depends. It is the standard method of measuring the strength of the yarn. The frictional forces rendered to the yarn in the lea test reduce the sensitivity of the test to detect weak places in the yarn.
What is yarn specification?
‘Count’ is widely used term in garment industry when it comes to defining fabric construction and yarn specification (weight per unit length or length per unit weight) those are made using staple fibre like cotton. … It means that the number of yarns of 840 yards length required weighing one pound.

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 CWC yarn?
Since 1871 CWC Textil AG is the synonym for high quality cotton yarns. The renowned handpicked Peruvian Pima cotton is distinguished by an extra long staple and its fineness. … With it the most precious fabrics can be produced.
What is yarn evenness?
YARN EVENNESS Yarn evenness is a measure of the level of variation in yarn diameter along its length. … A yarn with poor evenness will have thick and thin places along yarn length, while an even yarn will have little variation in mass or diameter along length.
What is yarn imperfection?
Imperfections can be defined as the total number of neps, thick and thin places in a given length of yarn. … A yarn with more imperfections will exhibit poor appearance grade, lower strength and poor performance in weaving is likely to produce fabric with low quality.

How is Lea strength calculated?
4. Calculation: Lea Strength = 79.32lbs/lea [120yards=1lea] C.S.P (CountStrength product) = Lea strength × Yarn Count =79.32×30 =2379.6 (C.S.P of given sample) Result: The strength of Cotton yarn = 79.32lbs/lea.
What is Lea of yarn?
noun. a unit for measuring lengths of yarn, usually taken as 80 yards for wool, 120 yards for cotton and silk, and 300 yards for linen. a measure of yarn expressed as the length per unit weight, usually the number of leas per pound.
How do you measure yarn strength?
Product strength score or CLSP
In this case, quality is usually expressed in pounds-force (lbf). The yarn strength is also measured in pounds, then multiplied by the English cotton yarn score to finally obtain the product strength score or CLSP.
