FZ/T 01057.1 Test method for identification of textile fibers - Part 1: General introduction
3 Terms and definitions
No terms and definitions are listed in this document.
4 Principle
Observe the longitudinal and cross-sectional morphological characteristics of unknown fibers with a microscope and/or microscopic image analyzer, and compare with those of known fibers to identify the types of unknown fibers.
5 Instruments, tools and reagents
5.1 Apparatus
5.1.1 Biological microscope, at least 100x magnification.
5.1.2 Microscopic image analyzer: containing microscope, camera, computer, acquisition card, special analysis software and display. The objective lens and eyepiece of the microscope shall be capable of providing a total magnification of at least 500x. A micrometer scale for calibrating the magnification of the instrument shall be provided.
5.1.3 Hastelloy microtome, which can cut fiber sections with a thickness of 10μm to 30μm.
5.1.4 Rotary microtome, which is equipped with concealed silent ratchet, crank slider and high-precision guide rail standard block, and can continuously cut fiber sections with uniform thickness. The adjustment range of section thickness is 1μm to 40μm.
5.2 Tools
5.2.1 Glass slide, 76.2mm×24.5mm×2mm.
5.2.2 Coverslip, 18 mm×18 mm or 24mm×24 mm.
