GB/T 35266-2017 in English

GB/T 35266—2017 Standard Overview

GB/T 35266—2017 "Determination of the Splitting Rate of Composite Ultrafine Fibers in Textile Fabrics" is an important national standard used to evaluate the splitting performance of stripped composite ultrafine fibers in textiles. This standard was proposed by the China National Textile and Apparel Council and is managed by the National Technical Committee for Textile Standardization.

Background of Standard Formulation

With the widespread application of ultrafine fibers in the textile field, the performance requirements for composite ultrafine fibers are increasing. The formulation of GB/T 35266—2017 aims to unify the testing methods and ensure the consistency of product quality and performance evaluation.

Technology Evolution Analysis

This standard combines advanced microscopy technology and image processing methods, which significantly improves the detection efficiency and accuracy compared to traditional detection methods. In particular, quantitative evaluation is achieved in the identification of the separation state (displaced fiber opening, split fiber opening) of composite ultrafine fibers.

Core determination method

The standard specifies the following main test steps:

1. Haggard slicer is used to slice the cross section of the yarn sample.
2. The slices are observed using a microscope with a magnification greater than 640 times, and cedar oil is used to improve the resolution.
3. A digital camera or automatic imaging system is used to take pictures and record the fiber opening status.
4. Computer image processing technology is used to count the number of displaced fibers, split fibers and unopened fibers.
