Metodos de Hilados: COBERTURA TOTAL

K₁= hilos de urdimbre/ pulg max Corb urd= hilos de urd/ pulg tela
    $\sqrt{\ }$ N°   hilos de urd/ pulg max

k₂= hilos de trama/ pulg max Corb trama= hilos de trama/ pulg tela
$\sqrt{\ }$ N° hilos de trama/ pulg max

CORB TOTAL= {(corb urd + corb trama) - (corb urd * corb trama) *100%}

Ejemplo 1
Calcular la cobertura total si tenemos:
N°u 22 K₁=hilos de urdimbre/ pulg max   hilos u/pul max= K₁ $\sqrt{\ }$ N°
N°t 18         $\sqrt{\ }$ N° = (26.9)( $\sqrt{\ }$ 22)= 123.82
hpp 50
ppp 70 hilos t/pul max= k₂ $\sqrt{\ }$ N° = 114.12
K_{1 y}k₂ 26.9
cob u= hpp = 0.40
     hilos de urdimbre/ pulg max

cob t= ppp = 0.56
  hilos de trama/ pulg max

COB TOTAL= {(corb urd + corb trama) - (corb urd * corb trama) *100%}
= {(0.40 + 0.56) - (0.40 * 0.56) * 100%
= 73.6%

Ejemplo 2
Calcular la cobertura total
N°u 14 hilos u/pul max= K₁ $\sqrt{\ }$ N°= 104.78
N°t 20 hilos t/pul max= k₂ $\sqrt{\ }$ N° = 125.21
hpp 70
ppp 55   cob u= hpp = 0.66
K_{1 y}k₂ 28 hilos de urdimbre/ pulg max

cob t=   ppp   = 0.43

hilos de trama/ pulg max

COB TOTAL= {(0.66 + 0.43) - (0.66 * 0.43) * 100%

= 81.3%

Ejercicio 3

Calcular cobertura total

hilos u/pulg max 98 cob u= hpp = 0.71

hilos t/pulg max 105 hilos de urdimbre/ pulg max

hpc 27.5*2.54=69.85

ppc 21.65*2.54=54.99 cob t= ppp = 0.52

K₁28.5 hilos de trama/ pulg max

k₂ 21.65

COB TOTAL= {(0.71 + 0.52) - (0.71 * 0.52) * 100%

= 86.08%

Ejemplo 4
Calcular la cobertura total
Npie 63.20 hilos u/pul max= K₁ $\sqrt{\ }$ N°= 206.69
Ntrama 55.70 hilos t/pul max= k₂ $\sqrt{\ }$ N° = 194.04
hpc 36*2.54=91.44
ppc 33.40*2.54=84.83
K_{1 y}k₂ 26 cob u= hpp   = 0.44
  hilos de urdimbre/ pulg max

cob t=   ppp   = 0.43
   hilos de trama/ pulg max

COB TOTAL= {(0.44 + 0.43) - (0.44 * 0.43) * 100%
= 68.08%

Ejemplo 5
Calcular coberttura total y los N
hilos u/cm max 105*2.54=266.7
hilos de trama/ cm max 98*2.54=248.92
hpc 27.55*2.54=69.97
ppc 21.65*2.54=54.99
K₁ 28.5 cob u= hpp   = 0.26
k₂ 36     hilos de urdimbre/ pulg max

cob t=   ppp   = 0.22
  hilos de trama/ pulg max

COB TOTAL= {(0.26 + 0.22) - (0.26 * 0.22) * 100%
= 42.3%

Nu=(266.7)2 =87.42 Nt=(248.92)2 =47.61

Ejemplo 6
Calcular la cobertura total
Nm pie 5200gns 900yds hpm 480   K₁ 59.57
Ne trama 80 oz 1500mts ppm 750   k₂ 20.15

Nm= (1gr/mt)(822.8mt)= 2.44 5200gns=336.95grs 900yds=822.8mts
336.95gr

Ne= (0.020oz/mts)(1500mts)= 0.37
80oz

Nm= Ne Km= (0.37)(1gr/mt)= 0.62
Ke 0.59gr/mt

hilos u/pul max= K₁ $\sqrt{\ }$ N°= 46.90
hilos t/pul max= k₂ $\sqrt{\ }$ N° = 31.47

cob u= hpp   = 0.25 480hpm=12.19hpp
hilos de urdimbre/ pulg max (480*0.0254)

cob t=   ppp   = 0.60 750ppm=19.05ppp
hilos de trama/ pulg max (750*0.0254)

COB TOTAL= {(0.25 + 0.60) - (0.25 * 0.60) * 100%
= 70%
