Product Design and Testing Laboratory
The Product and Design Testing Laboratory allows faculty and students to do innovative textile testing. Both chemical and physical tests can be conducted using this equipment. Below are descriptions of the most used equipment.
Students gain hands on experiences in measuring and comparing tensile strength of various fabric with woven and non-woven constructions. Our tensile tester belongs to the EJA vintage series and it is used to measure the amount of force required to break a variety of textile materials such as apparel fabrics, tissue paper, paper, and plastic film. This machine is also used in the laboratory portion of DHM 2573 Textiles class. We follow the standard ASTM 5034 (2013) for preparing test specimens.
Students can test the abrasion resistance of various fabric construction and compare the durability of fabrics that contain applied and structural finishes.Commonly referred as the Taber Abraser (abrader), was developed to conduct accelerated wear-testing. This machine is capable of giving reliable data on how textiles wear out, within couple of minutes where it could take years for the same data to be obtained from in-use testing. Standards followed for this test are ASTM F and ASTM D’s.
Students work with this machine to compare the colorfastness of different dyeing and printing techniques. This device is used to determine the color fastness of textiles to dry and wet rubbing. The Standard followed for this machine is AATCC 8 – Colorfastness to crocking. http://www.testextextile.com/
Students can determine fabricpilling and other related surface changes on textiles. Both knit and woven fabrics can be tested in this machine. The standard followed in our laboratory isASTM D3512.
Students test wrinkle resistance in both woven and knitted fabrics using this instrument. This instrument is used to induce wrinkling. A set of weights is supplied to permit compliance with ISO 9867, M&S P123, ENKA 3061 and AATCC 128.
Students can safely identify unknown fibers by immersing fibers in chemicals and determining the fiber content based on the reaction observed with the chemicals. Without the fume hood, this test is not possible to conduct as it guides the fumes of the chemicals out of the lab in a safe manner and protects the person from hazards fo inhaling chemicals.
Measures: Light absorbance, reflectance and transmission through materials; also able to test for color accuracy and/or discoloration and UV reflectance.
