AATCC TM20 Method for Fiber Analysis: Qualitative

Source：Besa Testing

Purpose:

To identify the general typesof commercial textile fibers through physical, chemical, and microscopic techniques, determine the specific fiber categories (e.g., natural, synthetic, protein-based fibers), provide abasis for textile quality control and composition identification, and comply with the requirements of the United States' Textile Fiber Identification Act.


Standard Definition:

Applicable tovarious types of textile products sold in the US market. It can be used to analyze fiber samples from raw fibers, yarns, or fabrics, covering natural fibers (cotton, wool, silk), synthetic fibers (viscose, lyocell), and man-made fibers (polyester, nylon). Key Terms: Fiber analysis.The method of identifying and analyzing the fibers used in textiles. Microscopic examination: A method of detecting the morphological characteristics of fibers at both longitudinal andcross-sectional levels through the use of a microscope. Solubility test: A method using solvents to detect the solubility, softening, or insolubility of fibers.


Testing and Certification Requirements:

Sample preparation: Representative fibers are collected and surface contaminants such as oils and starches are removed. Step-by-step testing: Initial morphological classification is performed using a microscope; subsequent validation is conducted through combustion tests (observing shrinkage, odor, and ash) or solubility tests. Complex samples areconfirmed using instruments like melting point determination and infrared spectroscopy.

Result interpretation: Fibers are compared to standard fiber characteristics to determine theirtype. Compliance requirements: Adherence to the latest version of the standard is required. Laboratories must be equipped with specialized equipment and reagents, and completetest records must be maintained.
