Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard is a revision of FZ/T 53003-1999 "polyester tops" of.

Instead of the standard FZ/T 53003-1999, compared with the original standard, in addition to editorial changes, the major technical changes are as follows.

--- Linear density from the original "2.80 ~ 3.90dtex (2.5 ~ 3.5d)" extended to "1.33dtex ~ 6.67dtex", the average length of the the original "is less than or equal to 100mm" extended to "less than or equal to 110mm", and an increase in extinction (see Chapter 1, Chapter 1 of the 1999 edition);

--- Increasing the product identification section (see Chapter 4);

--- The original "product class is divided into superior products, first-class product, second product, third-class products four grades lower than those for the third-class goods substandard goods" to "Products are divided into superior products, first-class products, qualified three levels below the qualified product is substandard products", delete the original 4.4.2 (see 5.1, 1999 edition 4.4);

--- Original by superior products, first-class product, second product, third grade specified target different products adjusted to the linear density range 1.33dtex ~ 2.10dtex, 2.11dtex ~ 3.32dtex, 3.33dtex ~ 6.67dtex products and superior products, first-class products, qualified unequal Level redefined index value (see 52, 1999 version 4.1.);

--- Increasing the linear density of the technical requirements (see 5.4);

--- Original 5.9 "180 °C dry heat shrinkage for determination of execution prescribed in Appendix A.8. Single fiber arbitration law" to "Press FZ/T 50004 regulations "(see 68, 1999 version 5.9.);

--- Revised chapter inspection rules (see 72, 1999 version 4.3.);

--- Packaging, labeling, transportation and storage of a chapter into signs, packaging, transport and storage, remove the logo and the packet number of different levels with different colors Predetermined color flag, an increase of non-fixed weight per package product quality and differentiation of products on behalf of the same batch of fixed weight does not exceed the quality of advice ± 5% over the requirement to retain and modify the packaging, labeling, transportation and storage of parts (see Chapter 8, 1999 edition Chapter 7);

--- Original title Appendix A supplement into a normative appendix, increasing the scope of chapter, an increase of online sampling methods; deleted 180 °C dry Shrink rate measurement and determination of moisture regain chapters, each test method to increase the test principle, increase the average length of a simplified calculation Formula (see Appendix A, 1999 edition of Appendix A).
