What is indirect system of yarn count?

The indirect system or fixed weight system is the yarn count system where the count of a yarn is calculated by measuring the length of a fixed / definite mass. In this system, the count of yarn is the number of length units in one weight unit. So, the count number indicates the length per unit mass of the yarn.

What is yarn numbering system?

In direct yarn numbering system the higher the yarn number or count indicates the coarser or thicker the yarn size and smaller the yarn number or count indicates the finer or lighter the yarn size. This system is generally used for Tex and Denier.

What is the difference between direct and indirect yarn count methods?

The direct system measures the weight of a consistent length of yarn, with a higher yarn count indicating a heavier and coarser yarn. The indirect system measures the length of a consistent weight of yarn, with a higher yarn count indicating a finer yarn. … The indirect system uses the formula: N = (L/w) / (W/l).

What do you understand by Universal count?

A universal Counter is a one piece combined unit that has in it all the circuits for measurement of frequency, time period, frequency ratio etc. Desired functions can be selected using the function switch.

What is yarn count in knitting?

The yarn count expresses the thickness of the yarn, and must be known before calculating the quantity of yarns for a known length of fabric. The yarn count number indicates the length of yarn in relation to the weight. … The fixed length system and the Tex system are based on metric weights and measures.

What does NM mean in yarn count?

The Nm stands for ‘normal metric’ – which is based on 1 000 metres of yarn per kilogram. The first number refers to the number of strands plied together. The second number tells you how many hanks of 1 000 metre lengths of a single ply of the yarn would weigh one kilogram.

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. …

What is worsted count?

The number of hanks ( skeins) having the length of 560 yards in one pound of yarn is called worsted count. It is used to express the fineness of worsted yarn. The fineness of yarn increases when yarn count increases in this system.
