Conversion of Yarn Count System (Indirect to Indirect and Direct to Direct):
1. Indirect to Indirect System:
{(lk / lr) × Nk}
Nr,= …………………………
(wk / wr)
Where,
Nr = Count of required system,
Nk = Count of known system,
lk = Unit length of known system,
lr = Unit length of required system,
wk = Unit length of known system,
wr = Unit weight of required system.
2. Direct to Direct:
{(wk / wr) × Nk}
Nr,= ……………………………
(lk / lr)
Calculation of Conversion Factor:
1. How to Convert English Cotton Count to Metric?
Indirect to indirect system:
In English system,
Here,
Lk = 840yds = 840 × 0.9144 × 103 km
wk = 1 pound
Now,
{(lk / lr ) × Nk}
Nr,= …………………………
(wk / wr)
Or,
[{(840 × 0.9144 × 103 km) / 1km} × Ne]
Nm = …………………………………………………………………………
{(453.6 × 10-03 kg) / 1kg}
= 1.69 × Ne
So,
Nm = 1.69 × Ne
2. How to Convert Denier to Tex?
Direct to direct system,
In denier system,
wk = 1gm
lk = 900m
In tex system,
wr = 1 gm
lr = 1km = 1000m
Now,
{(wk / wr) × Nk}
Nr,= ……………………………
(lk / lr)
Or,
{(1gm / 1gm) × Ndenier}
Ntex = ……………………………………
(9000m / 1000m)
= Ndenier /9
So,
Ndenier = 9 × Ntex
3. How to Convert English Cotton Count to Denier?
Indirect to direct system,
In English system,
wk = 1 pound = 453.6gm
lk = 840yds = 840 × 0.9144m
In denier system,
wr = 1gm,
lr = 9000m
Now,
(wk / wr)
Nr= ……………………………
{(lk / lr) × Nk}
Or,
(453.6gm / 1gm)
Ndenier,= …………………………………………………….
[{(840 × 0.9144m) / 1m} × Ne]
= 5315 / Ne
So,
Ndenier, × Ne = 5315
