Foreword
This standard was drafted in accordance with GB/T 1.12009 given rules.
Instead of the standard FZ/T 010401995 "Tex system twist factor." Compared with the FZ/T 010401995 major changes are as follows.
 Standard name was changed to "textile Turks (Tex) manufactured twist factor";
 Chapter 2 original standard references adjusted by reference, successively postponed later chapters;
 Increasing the twist, twist of terms and definitions, revised the definition of twist factor (see Chapter 2, Chapter 3 of the 1995 edition);
 Remove the twist factor and the related calculation formula αk represented (see Chapter 3, Chapter 4, 1995 edition);
 Remove the conversion formula and αk associated (see Chapter 4, Chapter 5, 1995 edition);
 Fixed conversion coefficient table section will αm 'corrected to αm, remove the related αk conversion factor (see Chapter 5, 1995
Chapter 6 edition);
 Note 2 in Table 1 metric twist unit "twist/10cm" was changed to "twist/m", delete the Note 3.
This standard uses the redrafted law revision using ISO /T R8091. 1983 "Textiles Tex system twist multiplier" (in English). The standard
The main difference between quasiISO /T R8091 as follows.
 The reference international standard adjustment of the corresponding standards, and added GB/T 3291.1;
 Chapter 2 adds the twist, twist the definition;
 Chapter 5 in terms of the relationship between an increase in note 1, "of the results of rounding conversion factor Description" and Note 2 of the "Metric and inch twist factor
The formula ";
 Remove the original international standard Chapter 7 twist multiplier unit conversion table and Chapter 8 twist factor conversion table.
The standard proposed by China Textile Industry Association.
The standard basis by the National Textile Standards Technical Committee of Standardization Technical Committee (SAC/TC209/SC1) centralized.
This standard was drafted. Textile Standard (Beijing) Co., Inspection and Certification Center.
The main drafters of this standard. Gongying Qiu, Liu Tao, Fang Xijiang.
This standard replaces the standards previously issued as follows.
 FZ/T 010401995.
Textiles Turks (Tex) system twist multiplier
1 Scope
This standard specifies the calculation formula and Tex system twist multiplier related to SI units, and other units common
Conversion relation and conversion factors twist factor twist factor and SI units system units represented.
This standard applies to all kinds of twisted staple yarn, filament yarn, strands and cables.
2 Terms and definitions
The following terms and definitions apply to this document.
