Textiles and Apparel Science Lab
The Textiles and Apparel Science Lab uses equipment to test the physical and chemical properties of textile materials to assess their serviceability.
Students gain hands on experiences in measuring and comparing tensile strength of various fabric with woven and non-woven constructions. Our tensile testing machine can give highest 5kN of load. 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. A dedicated computer is equipped with the tensile tester to record and analyze through software. We follow standard STM 5034 and ASTM 5035 for preparing test speciments. We also have a Thwing Albert tensile tester, which belongs to the EJA vintage series.
The abrasion tester is used to determine the response of textile structure to abrasion. 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), it was developed to conduct accelerated wear testing. This machine is capable of giving reliable data on how textiles wear out within couple of minutes when 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.
