--- the silkworm twisted yarn does not assess the strength of the project requirements of the nominal fineness from the "200denier (222.2dtex) above" modified to "70denier (77.7dtex) or more" (see 5.3,.2008 version 5.2); - deleted "re-check" (see

--- "Each batch of silkworm twisted yarn should be attached with quality and weight inspection certificate" (see the.2008 edition of 9.2.3). This standard is proposed by China Textile Industry Federation. This standard is under the jurisdiction of the National Silk Standardization Technical Committee (SAC/TC401).
