Fabric strength testing? Tensile strength testing: This is referred to as a strength test where the load is applied along the direction of the test sample. Tensile strength test of fabric is divided into two groups- 1. Strip test and 2. Grab test. 👉Strip strength test: i. Five fabric samples are extended in a direction …
Crease Resistance Introduction The crease is a fabric defect evidenced by a break line or mark or folds in a fabric generally caused by a sharp fold. Crease appears when the fabric is distorted in such a manner that part of it is stretched beyond its elastic recovery. During creasing the upper surface of fabric goes …
Working Principles: A transmission electron microscope fires a beam of electrons through a specimen to produce a magnified image of an object. TEM working flows. A high-voltage electricity supply powers the cathode. The cathode is a heated filament, a bit like the electron gun in an old-fashioned cathode-ray tube (CRT) TV. It generates a beam …
Working Principles: Produces images of a sample by scanning the surface with a focused beam of electrons. Electrons from the beam hit the surface of the sample and bounce off it as the secondary electron, backscattered electron etc. A detector registers these scattered electrons and turns them into a picture. SEM Working flows. Electrons are …
Working Principles: X-rays are collimated and directed onto the sample. As the sample and detector are rotated, the intensity of the reflected X-rays is recorded. When the geometry of the incident X-rays impinging the sample satisfies the Bragg Equation, constructive interference and a peak in intensity occur. A detector records and processes this X-ray signal …
To evaluate how something works under certain established methods or test standards. Textile testing is to check its properties under certain conditions in a standard environment prescribed as per Test standards. What is textile testing? |What are the main steps in textile testing? Checking raw materials Monitoring production Assessing the final product Investigation of faulty material Product development and research …
