Dr Michael Pailthorpe, Professor in Textile Technology at the ... fabrics was measured and the calculations were performed over the spectral region 280-390 nm using a Cary 3E … Formula for Calculating Fabric Weight based on … All the subsequent issues are made at the price calculated until next lot is received. textile testing methods 1. INTRODUCTION Fabric testing is an important segment of the textile industry. 3. Unfortunately, this method exposes subjects to potentially unsafe levels of UV radiation. By means of instruments: Apparatus required. Round GSM cutter and GSM Pad; Weighing Balance. Using these methods, textile engineers can explain to manufacturers how thick a yarn is and, therefore, how fine it is, in addition to finding information about its comfort and strength. Chapter 7 highlights different theories and structural parameter of fabric geometry, while chapter 8 includes specialty calculations like terry towel, ball warping, filament warping and sample warping. Method: - Cut 5 swatches from the different place of the fabric. L = {0.0655(D-d)(D+d)}/t Where L = Length of material (Feet) t = Thickness of fabrics (inches) D = Outside diameter (inches) d = Inside diameter (inches) The weight of yarn in a cloth A new price is calculated when new materials are purchased. Though knitting production is simple, its technical parameters calculation is complicated and difficult than weaving. Thus, the clerical work is simplified and reduced. Knit fabric production is easier and quicker than weaving technique. Fabric GSM means the weight of one square meter fabric in grams. But the most reliable fabric shrinkage test method for determining the shrinkage is preparing the sample for the test. Technical parameters involved in the knit fabrics are: loop structure, loop/stitch length, CPI ,WPI, GSM, shrinkage, spirality, fabric width etc. Standard Test Method for Pile Fabric Abrasion: D4772 - 14(2019) Standard Test Method for Surface Water Absorption of Terry Fabrics (Water Flow) D4850 - 13(2017)e1: Standard Terminology Relating to Fabrics and Fabric Test Methods: D4851 - 07(2019)e1: Standard Test Methods for Coated and Laminated Fabrics for Architectural Use: D4964 - 96(2020) The basis of calculation in the method is simple as the price is calculated by dividing the value of materials by their quantity. Textile standards: Standard is a … calculations, while chapter 6 is weaving shed calculations. To calculate the length of any rolled fabrics, this formula gives the nearest accuracy. 7 Fiber Properties and Test Methods Examples of Fiber ... Construction Test Methods • ASTM D3776 -Fabric Weight • ASTM D1777 –Fabric Thickness • ASTM D3775 –Warp and Filling Count • ASTM D1059 -Yarn Number There are many methods for determining the shrinkage of fabric. GSM is also written as gm/m2. Methods For Calculation Of Fabric Shrinkage. TEXTILE TESTING METHODS 2. We can easily detect the faults of machinery and materials during test of textiles. You can calculate GSM for woven and knitted fabric using one of the following methods. Formula for Fabric Weight Calcualtion - Free download as Excel Spreadsheet (.xls), PDF File (.pdf), Text File (.txt) or read online for free. The chapter 9 is dedicated to the knitting calculations, both warp and weft knitting. Fabric weight calculation method is: the finished product weight per meter (g/m) = (meridian quantitative practising discount rate + parallel quantitative x x the discount rate) present dyeing and finishing shrinkage (1) the discount rate: smelting turnning yarn after dyeing and finishing (silk). A calculation to determine if the mean values for 2 data sets are significantly different. The fabric shrinkage testers are in a wide range.
