Bursting Strength ASTM D 6797-2015 Objective: Lab 14 To interpret data for four different fabrics for their appropriateness and compatibility. Use results below to determine which two fabrics are appropriate and compatible together for a knitted lined jacket. Standard Deviation BURSTING STRENGTH 29 Questions 4: Based on t-test, will your chosen fabrics be compatible with each other? Number of servations was 5 for each fabric. Table value of t-test for null hypothesis at 95% level of confidence is + 2.306. Fabric Mean* Wales Courses Wales Courses Wool 100.245 80.246 15.254 8.532 Silk 125.875 103.783 5.873 5.349 Polyester 150.678 120.768 2.548 3.972 Acrylic 86.248 78.587 9.679 7.348 *Units of strength are pound per square inch (psi). Passing standard for bursting strength is 50-psi minimum for the fashion fabric, and 25-psi minimum for the lining material. Question 1: Based on the standard given above, which fabrics will pass for fashion fabric? Silk Question 2: Based on the standard given above, which fabric will pass for lining? Wool, Silk, polyester and Acrylic Question 3: Which two fabrics will you use together for a lined jacket conceptually? Based on the above analysis I would use silk and polyester for a lined Jacket.
