Foreword

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

This standard replaces GB/T 24252-2009 "silk quilt", compared with GB/T 24252-2009, the main technical changes are as follows.

---In the scope, the provisions of "Silk silk made from other silkworms as the main raw material can be referred to" (see Chapter 1,.2009)

Chapter 1 of the edition);

--- Revised the terminology and definition of "silk quilt" and "silk silk", added the terminology and definition of "silk quilt" and "small point", and deleted "filament Mian" "middle filament cotton" "short silk cotton" terms and definitions (see 3.1~3.3, 3.5,.2009 version 3.1~3.5);

--- Increased the safety performance of the tire cover and filler in the silk quilt should meet the requirements of GB 18401, among which infants and children's products The safety performance shall comply with the requirements of GB 31701 (see 4.3);

--- Modified fiber content, oil content, filler quality deviation rate and compression resilience requirements, increased filler silk length, residual glue Rate and requirements for fluorescent whitening agents (see 4.4, 4.3 edition of.2009);

--- Added the requirement that "silk fillers should not be subjected to weight gain treatment" (see 4.5);

--- Increased the appearance quality of the filler (see 4.6);

---Incorporate the "needle" requirements in the appearance quality into the "sewing quality" in the process quality (see 4.7, 4.4, 4.5 of the.2009 edition);

--- Increased the "filler quality of 500g and below products do not assess the degree of uniformity and the four corners, sides" provisions (see 4.7);

--- Added the requirement of "metal residues that may cause damage to the human body such as seamless needles and broken needles in silk" (see 4.9);

--- Revised the test method for fiber content, oil content, fluorescent whitening agent and water washing dimensional change rate (see Chapter 5,.2009 edition)

Chapter 5);

--- Increased safety performance, silk length and content, residual gel rate, silkworm weight gain identification, silk thread cleanliness and broken needles and other metal residues Test method for residues (see Chapter 5);

--- Revised the inspection items of the factory inspection (see 6.2.1, 6.2.1 of the.2009 edition);

--- Revised the specification of product specifications and fiber content (see 7.3, 7.4, 7.3, 7.4 of.2009 edition);

--- Amendment of Appendix A, added "representation of test results of filler fiber content" (see A.5.2 in Appendix A);

--- Appendix B is adjusted to "filling compression resilience test method", based on the original Appendix D, the test method has been modified and increased A schematic diagram of the test device was added, and the original chemical method for the determination of mulberry silk content in the mixed filler of mulberry and silkworm silk was deleted.

And refer to FZ/T 40005 (see Appendix B, Appendix B, Appendix D of the.2009 edition);

--- Appendix C is adjusted to "silk silk weight increase qualitative test acid dissolution color method", deleted the original Appendix C "oil rate test method" and Refer to FZ/T 40006 (see Appendix C, Appendix C of the.2009 edition);

--- Appendix D is adjusted to "silk cotton weight increase qualitative test high temperature acid hydrolysis method", the original Appendix D is changed to the current Appendix B (see Appendix B, Appendix D, Appendix D of the.2009 edition;

---Appendix E is adjusted to "Liquid Determination of Amino Acid Content in Silk", and the original Appendix E "Inspection Sampling Plan" is changed to the attached Record F (see Appendix E, Appendix F, Appendix E of the.2009 edition).

1 Scope

This standard specifies the requirements, test methods, inspection rules, marking, packaging and storage of silk quilts.

This standard is applicable to the production of silkworm cotton and tussah silk as the main raw material, and the tire is made and fixed with the tire cover (including machine seam and hand seam).

Into the silk quilt. Silk made from other silkworms as the main raw material can be referred to.
