The requirement for the change rate difference of the edge size of woven fabrics should be changed to "≥ -1, ≤+1"; The requirement for appearance retention (fabric flatness) after washing has been changed to level 4. Change the requirement for the relaxation size change rate (warp and weft) of woven blankets to -4, and change the requirement for the felting size change rate (warp and weft) to -5; Change the requirement for the relaxation size change rate (warp and weft) of the tufted blanket to -4, change the requirement for the felting size change rate (warp and weft) to -5, and change the felting washing program to 1 × 5A. Change the names of projects that include "shrinkage rate" to "size change rate". Added the symbol "≥" or "≤" before the requirement—— Cancel the original standards of Tables 3 and 4, and include the washing procedures and cycle times of wool knitted and wool woven products in the anti shrinkage performance assessment requirements table. This standard is proposed by the China Textile Industry Federation. This standard is under the jurisdiction of the Wool Textile Sub technical Committee of the National Textile Standardization Technical Committee (SAC/TC209/SC3). The drafting unit of this standard is the Inspection Center of Beijing Wool Textile Science Research Institute. The main drafters of this standard are Li Lirong and Li Jun.
