Testing Lab Report Introduction Objective measurement is a scientific way to get a good understand about some basic properties of fabric. In this lab, FAST system can provide the accurate measurement to show compression, extension, bending and stability of fabric. The aim of this test is to predict how a fabric will perform when made up into a garment. For fabric manufactures,finishers and garment manufacturers, they can use the results of this test as a basis to do fabric specification, product and process development, quality assurance and process control(Giorgio M. Pier, 1995). Experimental 2.1 Test Methodology The F.A.S.T system, which was developed by the Australian International Wool Bureau, consists of three…show more content…
Figure 6 and Figure 12 is the average thickness. Table II (Figure 1-12) Using these data, the average surface layer thickness can be easily calculated by following formula. Average Surface Layer Thickness （ST） = T2-T100 ST = 0.9940mm WEIGHT (g/㎡) Weight (w)= Weight (w)=168 (g/㎡) FAST-2 Table III and Table IV illustrate the banding length of warp yarn and weft yarn. Figure 13-16 show the length of face and Figure 17-20 show the back. In this part, bending length can be converted into bending rigidity using formula. Warp: Table III (Figure13-20) Sample ID A B C Average(mm) Face:Cf (Figure13-16) 15.5 15.5 15.0 15.33 Back:Cb (Figure17-20) 14.5 14.5 15.0 14.67 Average Warp Banding Length (C1)=(Cf+Cb)÷2 C1=15.00 mm Warp Banding Rigidity (B1)=W×C1³×9.81×10 B1=5.56 µN.m Weft: Table IV (Figure21-28) Sample ID A B C Average(mm) Face:Cf (Figure21-24) 14.5 14.0 14.0 14.17 Back:Cb (Figure25-28) 15.0 14.5 15.0 14.83 Average Weft Banding Length (C2)=(Cf+Cb)÷2 C2=14.50 mm Weft Banding Rigidity (B2)=W×C2³×9.81×10 B2=5.02 µN.m FAST-3 Table V, Table VI and Table VII reveal the fabric extensibility in warp, weft and bias
