Production Calculations on Flat Knitting Machines
• Production Calculations on Flat Knitting Machines

Number of Stitches Produced per Hour

nx 2 x SS x R x 60

UISS = --------------------------------

RS

UISS = Number of rows of loops produced in an hour (row / h)

n = Number of revolutions (rpm)

SS = Number of Systems

R = Machine efficiency ( % )

RS = Number of colors (will be considered for jacquard products)

Fabric length produced per hour

UIIS

UKM = --------------------------

S x 100

UKM = length of fabric produced in one hour (mt)

UIIS = Number of rows of loops produced in an hour (row / h)

S = Row spacing ( at 1 cm )

Fabric produced in one hour in square meters

Production in square meters of fabric produced in one hour = UKM x KE

UKM = length of fabric produced in one hour (mt)

KE = Fabric Width ( mt )

Number of parts produced per hour

UKM x 100

UPS = --------------------------

PB

PPS = number of parts produced per hour

UKM = amount of fabric produced per hour ( mt)

PB = Piece length ( cm )

Weight of fabric produced in satte

UPS x HP

UKM = ----------------------

1000

UKM = Production amount per hour ( kg )

PPS = number of parts produced per hour

BG = Unit weight (gr / piece)

L = I x CS x B

L = Length of yarn used in a row (mt/row)

I = Loop thread length ( cm )

CS = number of bars per cm.

B = Fabric width (mt)

Amount of thread used per hour

L ( m/h) = L x UISS

L ( m / h ) = Length of thread used in one hour

L = Length of yarn used in a row (mt/row)

UISS = Number of rows of loops produced in an hour (row /h)

BÖSS : Number of rows in body knitting length

Necessary Calculations for Arms

Number of needles for sleeve:

KG x D

WMD = ------------------------

10

CI: Number of arm needles

KG : Arm width

D= the number of loop bars in 10 cm.

Number of armhole rows:

Rank x KU

KASS. = -------------------

10

CSR : Number of rows of armholes

Row: row density at 10 cm

KU: Side length

Number of rows in arm length

Rank x KB

KBSS = ---------------

10

KBSS : Number of rows at arm length

Row : Row frequency at 10 cm

KB: arm length

Number of whole rows at sleeve length:

KTSS = CSR + KBSS

KTSS : All rows in arm length

CSR : Number of rows of armholes

KBSS : Number of rows at arm length

Knitting Time for Collar

TYSS

nx 2 x WSG

FACE : Collar knitting time (min.)

TYSS : Number of rows required for the entire collar

n : Machine speed (rpm)

WG : Workplace width

Knitting Time Calculation for the Whole Sweater

BTSS

OAZ. = ------------------------

nx 2 x WSG
