Problems solved by technology

[0005] It can be seen from the above-mentioned prior art that by adding functional ceramic powder or adding functional fiber, the fabric can be endowed with far-infrared and other characteristics, but most of the current functional fabrics simply consider the functionality and comfort of the fabric, and do not start from infants and young children. Considering the safety and comfort of fabrics from the perspective of special physiological characteristics, it is necessary to develop a far-infrared textile material suitable for infants and young children.

Abstract

The invention provides novel far-infrared cotton fiber suitable for infants and children and a preparation method of the novel far-infrared cotton fiber. The preparation method comprises the following steps: (1) adding biological protease into a sericin solution obtained after natural silk degumming for a reaction, and taking out a product I for freeze drying, so as to obtain a hydrolysis product of sericin polypeptide; (2) placing cotton fiber into a gaseous nitrogen dioxide environment to conduct photophobic oxidation on primary hydroxyl groups of cotton fiber, and taking out a product II for vacuum standing, so as to obtain oxygenated cotton fiber; (3) placing the hydrolysis product of the sericin polypeptide into deionized water, stirring, adding nano ceramic powder and sodium alginate, and stirring uniformly to obtain a sericin-contained far-infrared treatment liquid; (4) putting the oxygenated cotton fiber into the sericin-contained far-infrared treatment liquid, carrying out impregnating and oscillation, and taking out for pre-baking, baking, water washing and drying to obtain the novel far-infrared cotton fiber suitable for infants and children. The novel far-infrared cotton fiber has excellent far-infrared performance without impacting the performances such as mechanical strength, softness, close-fitting performance, hygroscopicity and air-permeability.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a far-infrared cotton fiber suitable for infants and young children and a preparation method thereof. Background technique: [0002] With the gradual popularization of the concept of safe dressing, with safety and environmental protection as the overall requirement, children's clothing has also changed from the basic attributes of pure beauty and durability to the attributes of safety, health, comfort, function and beauty. The new children's clothing products are more scientific and rational. , more and more favored by parents and children. Moreover, with the continuous development of science and technology and people's continuous attention to health and safety, various functional fibers continue to appear, and processing technology continues to innovate. The range of subdivision applications is also continuously expanding. [0003] The main component of ...
