The testing laboratory of the Textile Physics Division comprises Fibre, Yarn and Fabric testing sections. The laboratory has received ISO/IEC 17025 Accreditation from the National Accreditation Board for Testing and Calibration Laboratories (NABL). NABL, a Government of India body under the Department of Science and Technology, is a part of an international arrangement known as International Laboratory Accreditation Cooperation (ILAC). With this accreditation, SITRAs test reports are valid in all countries which are signatories to ILAC arrangement, thereby eliminating re-testing of textiles by the foreign buyers. All the fibre, yarn and fabric tests are carried out as per ASTM, IS, BS, BIS, BISFA and in-house standards.

Fibre Testing

The important characteristics of cotton and man-made fibres are tested for various end-use requirements. Cotton fibre properties such as length, strength, fineness, maturity and trash content are tested by both conventional and high volume instruments. In the case of man-made fibres, the characteristics such as staple length, crimp interms of number of arcs per inch, tenacity, elongation and force elongation curves are analysed. Some of the state-of-the-art instruments used in the laboratory are High Volume Instrument (HVI), Advanced Fibre Information System (AFIS), Lenzing Vibromat and Vibrodyne, Fibroglow and Instran Tester.

Yarn Testing

The laboratory is equipped with modern sophisticated instruments such as Uster Tester 3 and 4, Uster Tensorapid and Tensojet, Zweigle Yarn Hairiness G 565 & G 566, Uster Classimat System III and quantum, Constant Tension Transport (CTT) and Electronic Inspection Board.

Fabric Testing

Fabric testing laboratory is equipped with all necessary instruments for testing cloth and garment.

The physical laboratory of SITRA is also equipped with instruments for micro level analysis such as Image Analyser and Scanning Electron Microscope (SEM).
