Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" drafted.

This document replaces GB/T 22848-2009 "Knitted Fabrics". Compared with GB/T 22848-2009, except for structural adjustment and editorial In addition to the changes, the main technical changes are as follows.

--- Changed the scope of application (see Chapter 1, Chapter 1 of the.2009 edition);

--- Added specification examples (see Chapter 4, Chapter 3 of the.2009 edition);

--- Changed the bursting strength requirements (see 5.2.1, Chapter 4, Table 1 of the.2009 edition);

--- Increase the requirements for color fastness to light, composite color fastness to light and sweat, and the degree of staining of lotion (see 5.2.1);

--- Changed the requirements for the distortion rate after washing (see 5.2.1, Chapter 4, Table 1 of the.2009 edition);

--- Changed the assessment requirements for the rate of change in washing dimensions (see 5.2.1, Chapter 4, Table 1 of the.2009 edition);

--- Delete the requirements for infants and young children in the color fastness to perspiration, water and rubbing (see 5.2.1, Chapter 4, Table 1 of the.2009 edition);

--- Added detailed assessment requirements for pilling (see footnote a in 5.2.1);

--- Changed the detailed assessment requirements for the bursting strength of hollow fabrics (see footnote b in 5.2.1, Table 1 of the.2009 edition);

--- Increased the detailed assessment requirements for the rate of change in washing dimensions (see footnote c in 5.2.1);

--- Increased the range of color fastness not tested for natural and bleached products (see footnote d in 5.2.1);

--- Increased the detailed assessment requirements for light fastness, light fastness, perspiration composite color fastness and fluorescent fabrics (see footnote e in 5.2.1);

--- Increased the detailed assessment requirements for the degree of staining of the lotion (see footnote f in 5.2.1);

--- Increased the requirements for knitted finished fabrics for infants and children's products (see 5.2.3);

--- Changed the appearance quality requirements (see 5.3, Chapter 4 of the.2009 edition);

--- Changed and improved the specific requirements of the pilling test method (see 7.7, 6.8 of the.2009 edition);

--- Changed and improved the washing program of the dimensional change rate of washing (see 7.9, 6.9 of the.2009 edition);

--- Increased the twist rate test method after washing (see 7.10);

--- Increased the color fastness to light, the composite color fastness to light and sweat, and the test methods for the degree of staining of the lotion (see 7.15, 7.16, 7.17);

--- Added comprehensive judgment and re-inspection (see 8.3, 8.4);

--- Increased packaging, marking and storage (see Chapter 9).
