Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 398-2008 "cotton color yarn". Compared with GB/T 398-2008, the main technical changes are as follows. --- Adjusted the classification and marking of yarns, moved the standard quality calculation of the 100-meter yarn to Appendix B, and canceled the cotton yarn Weigh the series of linear density and its standard weight of 100m (see Chapter 3 of the.2008 edition); ---The linear density deviation rate (original "100m weight deviation"), linear density coefficient of variation (formerly "100m weight coefficient of variation"), single yarn break The strength has been adjusted, and the requirements for the evaluation of the kilometer cotton knot have been increased, and the appearance of the blackboard such as the uniformity of the single yarn and the horizontal line of the strand has been eliminated. Quality assessment requirements, the number of black slabs and the total number of impurities in the blackboard neps are classified into Appendix A (informative appendix), Party agreed to assess (see Table 1 to Table 4, Table 4 to Table 7 of the.2008 edition); --- The stock index has increased the coefficient of variation of the coefficient of variation (see Table 2, Table 4); --- Removed the provisions of the weaving yarn for weaving (see Table 8, Table 9 of the.2008 edition); --- Cancel the number of tubes and the number of trials, adjust to directly sample the finished product, the number and number of samples according to the requirements of each test method Execution (see Table 11 of the.2008 edition); --- Removed the original Appendix A strong correction factor (see Appendix A of the.2008 edition); --- Removed the numerical revision of the calculated value (see Table 12 of the.2008 edition). This standard was proposed by the China National Textile and Apparel Council. This standard is under the jurisdiction of the National Textile Standardization Technical Committee (SAC/TC209).
