Question

A 3-ply core/sheath yarn consists of a 30/1 (core) yarn, and two 20/1 (sheath) yarns. Analysis of the plied yarn showed that 1 m of the plied yarn has 1.08 m each of the two 20/1 yarns, and 1 m of the core yarn. What is cotton count of the plied yarn? Show calculations.

Answer 1

Answer:

0.000462

Step-by-step explanation:

From the given information:

The cotton count of the piled yarn is the ratio of the simple weight in (g) with the length by the simple length with weight.

Mathematically:

$Cotton count = \dfrac{simple \ weight \ in (g) \times \ length }{simple \ length \times unit \ weight }$

$Cotton count = \dfrac{1 \times 0.001 }{0.108 \times 20}$

$\mathbf{ Cotton \ count = 0.000462}$
