Problems solved by technology

Different forms of calcium carbonate are suitable for different application scenarios due to the differences in their properties. However, in nature, many biomass raw materials often contain different forms of calcium carbonate. Generally speaking, it is difficult to combine calcium carbonate from the same biomass Calcium carbonate raw materials are strictly cut and classified according to their respective forms, thus limiting the widespread application of calcium carbonate in biomass raw materials

Abstract

The invention provides oyster fibers. The oyster fibers are prepared by the following steps of 1, dissolving oyster shell powder and chitosan in an acetic acid solution to obtain a reaction solution;2, adding a carbonate supply source substance into the reaction solution, so that the reaction solution is converted into a gelatinous solution; 3, heating the gelatinous solution to 80-120 DEG C, keeping the temperature for 10-15 hours, then adding omega-aminoalkanoic acid, and continuously keeping the temperature for 5-10 hours; step 4, adjusting the pH value of the mixed solution obtained afterthe step 3 is completed to be greater than 7.5, and then adding chloroacetic acid into the mixed solution until the chitosan is converted into carboxymethyl chitosan; 5, adding deionized water, carrying out ultrasonic treatment to fully dissolve the carboxymethyl chitosan, filtering, washing filter residues with the deionized water, filtering out washing liquor, and reserving the filter residuesfor later use; and 6, adding a dispersant into the filter residues, grinding, fully dispersing, fully mixing the ground mixed slurry with polyester, granulating, and spinning to obtain a finished product.

Description

technical field [0001] The invention belongs to the field of textile fibers, and in particular relates to an oyster fiber. Background technique [0002] Adding various inorganic particles is a common method in the modification process of polyester and fiber. By adding different inorganic particles, the modified polyester or fiber will have different functions. Calcium carbonate (CaCO 3 ) polyester made of microparticles, which are characterized by: ① The surface properties of polymer particles are improved, which is convenient for polyester film-forming processing; ② Films made of calcium carbonate modified polyester have higher dielectric properties and can meet Application requirements in some occasions; ③Synthetic fibers made of the modified polyester have improved crystallization and tensile properties under the premise of ensuring fiber gloss; ④Make the surface of the fibers microporous without affecting the strength , so that the fiber has new functions such as mois...
