FZ/T 43015---2001
Requirements are divided into two aspects: internal quality and appearance quality. Internal quality includes seven indicators, including fiber content, square meter dry mass tolerance, marble bursting strength, washing size change rate, color fastness, formaldehyde content, pH value, etc.; appearance quality includes four indicators, including part size tolerance, same piece size tolerance, appearance defects, sewing regulations, etc. 5 Grading Regulations
5.1 Mulberry silk knitted garments are divided into superior products, first-class products, and qualified products. 5.2 The quality of mulberry silk knitted garments is graded on a piece-by-piece basis. The internal quality is graded by review, the appearance quality is graded by piece, and the final product grade is determined by the lowest grade of the internal and appearance quality.
5.3 The internal quality rating is as specified in Table 1.
