Textile material properties and test terms6>Suitable for the end of the country 32982 Textile materials, textile products, general classification B? Textiles and textile products "vocabulary" revised, specifies the material properties and related terms with special tests. Compared with the original standard, "no major changes, 1. The standard title 3 is changed to unified! Group material properties and test terms 3, in order to test the performance of textile materials for new products The relevant technical evaluation is for stickers, not including original financial technology, product technology, appearance test technology, packaging language, etc. 2. The original standard is divided into multiple standards, including three parts: Part 1: Fiber line
Part 2: Design
Part 3: Open
3. Six parts are added, and some terms and definitions in the original standard are retained and revised. This standard is used as a medical textile material. The second part of material performance and test terminology also includes the terminology of fiber protection. Textile material performance and test terminology replaces the old terminology (textile materials, textile products, general part B457 and G3291) from the date of entry into force. The fifth part of the industry standard F70-192 Anti-sparse fabric woven fabric technical notice A and the attached requirements are included in the attached requirements. The production standard is issued by the China Textile Federation and the National Textile Standardization Technical Committee is responsible for the production standard sub-technical committee. This standard is issued by: China Textile Federation Standardization Research Institute. The main drafter of this standard is: Scope National Standard of the People's Republic of China Textile Textile Material Performance and Test Terminology Part 1: Fibers and Yarns Textilrs-Ierms 1.Fihre and yara
This standard defines the terminology for the performance of yarns in accordance with the standard test. 2 Definitions
The following definitions are used in the technical notation.

After the fiber is swollen, the shape of the fiber turns to the shape of the pants, and the cell rate is fully affected. The cell rate is fully affected. The cell rate is 2.7
, the actual cross-sectional area of the fiber is 2.8f, and the maturity coefficient is an indicator of the maturity of the fiber structure. According to the value of the fiber cavity and the thickness of the test, the thermal coefficient is 2.9%. The increase in the degree of artificial selection of the standard pressure is 57. 2. The percentage of maturity is the average percentage of the total effective number of red fibers in the test index. 2.11 The micron value is the standard for the quality of the sample under the condition of maintenance, which is the comprehensive standard for the quality of the sample and the degree of maturity. It is shown in the table of GH/T 3251.1-1997 approved by the State Technical Supervision Commission on October 9, 1998 and implemented on May 1, 1998. 2.12 Note: The micron value shall be based on the standard cotton standard specified by the International Cotton Commission. The sample shall be specially prepared and selected, and approved by the standardization management department as the standard sample. It has a predetermined standard value or several physical properties, but the standard value corresponds to the standard density. 2.13 The above properties are determined by a professional laboratory of Xtronstaadardsmles. 2.14 Fiber length distribution indicates the distribution of different length fibers according to the number of roots. 2.15 Fiber length array indicates the distribution of single fibers or fibers in a certain order. 2.16 Length group
