GB/T 35443-2024 "Spinning & Weaving Products, Quantitative Chemical Analysis, Mixtures of Seaweed Fibres with Certain Miscellaneous Fibres" describes in detail the method of determining the content of seaweed fibres in two-component mixtures of seaweed fibres with cotton, linen, copper ammonia fibres, viscose fibres, modal fibres, lyocell fibres, polypropylene (PP) nitrile fibres, polyester fibres, polyamide fibres, spandex, mulberry silk, sheep wool, cashmere, cool ester fibres, triacetate fibres or polylactic acid fibres by means of chemical analysis. This standard is applicable for analysis after removal of non-fibrous substances to ensure accurate calculation of the content of seaweed At the same time, the standard refers to a series of relevant quantitative chemical analysis method standards, including GB/T 2910.1, GB/T 2910.3, GB/T 2910.10, GB/T 2910.11, GB/T 2910.12 and GB/T 2910.18, to ensure the scientific and accurate analysis process.
