woven sack tutorials




Here is description with an example for you, For a bag how to calculate its basic data to start manufacturing it. I have tried to explain with an example. suppose if we have a new bag to be manufactured. what we should have? some basic data like GSM,GPM,DENIER, TAPE WIDTH, MESH
etc.
I Have already given its formula in my blog, please check below!!!


if there is any confusion please let me help you.

Picks per minute = cam RPM x Number of shuttles Gear Ratio = Haul off gear ratio X no of teeth of Haul off  Sprocket  ÷ motor gear  Sprocket .  Weaving Ring I.D = 2 x fabric width(mm)/3.14 OR = 2 x fabric width(inch) x 25.4/ 3.14  Elongation = Increase in length x 100 / Initial sample length Number of warp = 2 x fabric width x Warp Mesh (Inches) = 2 x fabric width x Warp Mesh / 2.54 (centimeters) Fabric Production per minute = 1.524 x PPM / Weft mesh Fabric GSM = Warp mesh x Warp Denier + Weft mesh x Weft Denier/228.6 Bags Weight = 50.8 x fabric width x Cut length x Warp mesh x Warp Denier + Weft mesh x Weft Denier/ 90,00,000 = Fabric Dfl. x Cut length X GSM/ 5000 ( warp mesh and weft mesh in inches, fabric width and cut length in inches) » For PP Unlaminated Fabric For Example, If you want to Produce 60cm x 90cm single fold bottom stitch 90 gram bag. For Production you need Two Things 1. Cut Length and 2. Denier For Cut Length : ...

Spacer Size (mm) = (Stretching Ratio) ^1/2 x Width of Tape Stretching Ratio = ( Spacer Size/Tape Width )^2 Stretching Ratio = Stretching Godet Speed / holding Godet Speed Production Kg/hr = Denier x Final Line Speed x No of Tapes x 60 / (9000x1000) Production Kg/hr = Denier x Final Line Speed x No of Tapes/ 150000 Elongation % = Tape Final Length - Initial Length x 100 / Final Length Tape Thickness Stretched = denier / (9000 x Tape Width x Density) Unstarched Tape Thickness = (Stretch Ratio )^1/2 x stretched Tape Thickness Denier Setting Formula = Holding Speed x Actual Denier / Required Denier Denier to GSM Calculator Relaxation Speed = Stretching Speed - Annealing Speed x 100 / Stretching Speed Screw Speed Formula = Motor Speed x Motor Pulley  Diameter / ( Gear Ratio x Gera Box Pulley Diameter) Useful Width ( Flat Film) = Film Width - ( 2 x Spacer size) Main Motor RPM = (Gear Ratio X Screw RPM X Gear Box Pulley Dia) /( Motor Pulley Dia.)

Woven Fabric GSM Calculation - WOVEN SACKS PLANNING FORMULA

Image
  GSM stands for Gram per Square Meter. In simple words, it is the calculation of the weight in grams for one square meter fabric. In most cases, we need these calculations while we are in the preproduction phase. It helps us to precisely compute what denier we should run in our flat yarn tape line plant.  Polypropylene Woven Fabric  GSM Calculation can be done by various methods when different factors are given for calculation. We can calculate GSM of Polypropylene Woven Fabric when combinations of the following factors are given; 1.      Sack  Weight and area is given 2.      Mesh Size and  Denier  is given 3.      GPM  (Gram Per Meter) and Width of the woven fabric is given We will explain each method step by step to perfectly and accurately calculate the Woven Fabric GSM with examples.   Polypropylene Woven Fabric GSM Calculation by various methods   1. When Sack ...
