The Ministry of Industry and Information Technology of the People’s Republic of China announced that the revised Industry Standard FZ/T 81006-2017 < Jeanswear > will be officially implemented on the October 1, 2017. This revised standard will replace FZ/T 81006-2007 <Jeanswear>.

 

1. Applicable Scope

This standard applies to woven jeanswear which are mainly made of pure cotton or cotton fiber.

This standard does not apply to garments for infants (not older than 36 months).

    1. Revised the applicable scope of the standard

    2. Added and revised some normative references

    3. Revised the English translation of some terms, i.e. changed “Washing Product” to “Washed Jeanswear” and changed “Original Product” to “Unwashed Jeanswear”. Deleted the terms and definitions of “Regular Jeanswear” and “Colour Jeanswear”

    4. Added information for instruction for use

    5. Revised the requirements for raw material, shell and lining; added the requirements about “decorative laces”, “cords and drawstrings”, “elastic webbing” in accessories; revised the requirements for buttons, decorative buttons, zippers and other attached materials

    6. Revised the requirements for skewness of warp yarn and weft yarn

    7. Deleted the information about stitching fabrics

    8. Revised the specifications and requirements about appearance defects and revised relevant details in the table footnotes

    9. Revised the sewing rules: stipulating the specifications for different sewing threads; deleting the requirements about sewing buttons; and revising the requirements about marks and permanent labels.

    11. Revised the requirement about the symmetrical part in ironing appearance

    12. Revised the requirements for physical and chemical properties: added the provisions of “Jeanswear for children (36 months~14 years old) shall comply with the requirements of GB 31701”; revised the requirements for colorfastness to light; deleted the requirements for colorfastness for infant’s products; revised the requirements for breaking force; revised the requirements for abrasion resistance of finished products; revised the requirements for seam slippage; deleted the requirements on peeled off strength for garments adhesive interlining; added the requirements for jeans button attachment strength; added the requirements for appearance after washing; revised the requirements for general safety performance

    13. Revised the test method for the determination of appearance, revising the measuring method for the specification of finished products and yarn skewness

    14. Added the test method for physical and chemical properties: added the temperature of tumble drying for the test of dimensional change after washing; added the provision of sampling position for the test of abrasion resistance; revised the provision of sampling position and test method of seam slippage; added the test method of jeans button attachment strength; deleted the test method of peeled off strength for garments adhesive interlining; added the test method of appearance after washing; added the provision of “the test methods of other physical and chemical items shall be in accordance with GB/T 21294”.

    15. Revised the inspection rules for finished products

    16. Revised the information in Appendix A

    17. Revised the information in Appendix B

    18. Deleted the information in Appendix C and Appendix D

    19. Added the information in Appendix C

Instruction for use shall comply with the requirement of GB/T 5296.4 and GB 31701 and the words “Washed Jeanswear” or “Unwashed Jeanswear” shall be indicated in the instruction. If the jeanswear has undergone a special process, such as special abrasion process or a destructive washing process, it shall be indicated in the instruction.

4. Requirements for Physical and Chemical Properties

Jeanswear for children (36 months -14 years old) shall comply with the requirements of GB 31701. Physical and chemical properties for jeanswear products are given in Table 1.

Note: elastic products refer to those fabric products containing elastic fiber, e.g. elastane.

a For the dimensional change of collar after washing, only test products with stand-collar.

b For products with elastic waistband, do not test the dimensional change after washing of waist girth; for wrinkle products and elastic products, do not
test the dimensional change after washing along the width direction.

c Do not test this item when jeanswear products have undergone a special process such as special abrasion processing, destroy wash processing.

d Except jeans, do not test this item when the weight of fabric is below 245g/m2.

e For the test results of seam slippage, it will be judged as failed when pull-out, breakage and tears of fabrics or breakage of sewing threads occurs.

f Do not test this item when products cannot be sampled.

g Do not test this item on tops, shorts (skirts). Do not test this item for products with special design, for example, a large different between the width of front trouser piece and back trouser piece.
