Production Formula for Knitting Section


Knitting production is completely mathematical based. Knitting master or knitter or production manager of knitting section has to do lot of calculation for optimum production of knitting. I thing the following formula will help a knitter to find out better production .


***Production/shift in Kg at 100% efficiency, 

   RPM x No. of Feeder x No. of Needle x SL (mm) 
= ……………………………………………………………
                    3527.80 x Yarn count 

***Production/shift in meter, 

   Course/min 
= …………………
   Course/cm 

   RPM x No. of Feeder x 60 x 12 x Efficiency 
= ……………………………………………………
                   Course/cm x 100 

***Fabric width in meter, 

    Total no of wales 
= ………………………
    Wales/cm x 100 

   Total no. of needles used in knitting 
= …………………………………………
           Wales/cm x 100 

***Running Length (L), 

      Machine rpm x No. of Feeder x Efficiency x 60 
= ………………………………………………..............………. m/hr 
   No. of Feeders per course x Courses per cm x 100 

***Fabric width (WB), 

   Cylinder diameter in inch x Machine Gauge 
= ……………………………………………...……. m 
                 Wales/cm x 100 

***Production in Kg, 

   Running length in meter per hour x WB x Weight in GSM 
= ……………………………………………………….........………. Kg/hr 
                                        1000 

                                         Weight (in gm) x 39.37 
***Length Calculation = ……………………………… 
                                         Width (in inch) x GSM 

***Production per shift in KG at 100% efficiency, 

    RPM x no of feeder x no of needle x stitch length (mm) x 60 x 12 
= ……………………………………………………………….......………… 
                10 x 2.54 x 36 x 840 x 2.2046 x yarn count 

                                    Ks x 590.5 
***Stitch length = …………………………
                               Count (Ne) x GSM 

Where, 

Ks = knitting constant 
Count = linear density of yarn 
GSM = gm per square meter 

Another formula is: 

***Stitch length = (Tex × Ks) / GSM 

Ks is a constant. Its value is different for different fabric structure and fabric type. Ks is calculated and estimated as below: 

Ks = (GSM x Stitch length) / Tex
