Scope
GB/T 41553-2022 is the English-translated version of 竹纤维.
GB/T 41553-2022 is the Chinese national standard for bamboo fibre, the natural fibre obtained by processing bamboo. It gives the classification and the codes of bamboo fibres, specifies their technical requirements, and describes the matching test methods, the inspection rules and the packaging, marking, transport and storage.
It applies to natural fibres processed from bamboo as the raw material.
The test methods it cites show what is measured: acid-insoluble lignin and holocellulose content by GB/T 2677.8 and GB/T 2677.10, residual gum, length and fineness by the GB/T 18147 series, single short fibre tensile properties by GB/T 35378, fibre diameter by projection microscopy under GB/T 10685, whiteness by GB/T 17644 and moisture regain by GB/T 9994 and GB/T 9995. It was issued on 15 April 2022 and has applied since 1 November 2022.
