Embodiment 1

[0027] Weigh 2g of electric spinning silk, the liquor ratio is 1:50, the reactive cyclodextrin content is 10% (owf), and the temperature is raised to 85°C at a rate of 1.5°C / min at room temperature. After holding the reaction for 10 minutes, add 1g / L Na in two times 2 CO 3 After 45 minutes of treatment, the fabric was taken out, washed with water, and dried to obtain reactive cyclodextrin-fixed real silk.

Embodiment 2

[0029]Weigh 2g of electric spinning silk, the bath ratio is 1:30, the reactive cyclodextrin content is 5% (owf), and the temperature is raised to 85°C at a rate of 1.5°C / min at room temperature. After holding the reaction for 10 minutes, add 1g / L Na in two times 2 CO 3 After 45 minutes of treatment, the fabric was taken out, washed with water, and dried to obtain reactive cyclodextrin-fixed real silk.

Embodiment 3

[0031] Weigh 2g of electric spinning silk, the liquor ratio is 1:50, the reactive cyclodextrin content is 10% (owf), and the temperature is raised to 85°C at a rate of 1.5°C / min at room temperature. After 10 minutes of heat preservation reaction, add 2g / L NaHCO twice 3 After 45 minutes of treatment, the fabric was taken out, washed with water, and dried to obtain reactive cyclodextrin-fixed real silk.

Abstract

The invention relates to a Cyclodextrin fixing fiber with envelope property and a preparation method thereof. As for the Cyclodextrin fixing fiber, the Cyclodextrin is fixed on the fiber through the combination mode of a covalent bond; the fiber with envelope property is prepared from reactive Cyclodextrin containing triazinyl and vinyl sulphone and the fiber or fabric through bath finishing under the alkali condition. The processing technology of the fiber is simple and can realize industrialization easily, thus laying a foundation for further developing the functional textiles such as fragrance-keeping, health care, deodorization, mosquito-preventing textiles and the like.

Description

technical field [0001] The invention relates to a cyclodextrin-fixed fiber with enveloping performance and a preparation method thereof, belonging to the technical field of materials and textile fiber preparation. Background technique [0002] Cyclodextrin (abbreviated as CD) is a cyclic oligomer formed by a certain number of glucose molecules linked by glycosidic bonds. Substrate and guest molecules of appropriate size can perform functions such as shielding, controlled release, and activity protection. Therefore, the good enveloping properties of cyclodextrin and its derivatives can be organically combined with fibers or fabrics to form different functional textiles to meet people's different needs. At present, the methods for fixing fibers by cyclodextrin and its derivatives mainly include physical and chemical methods. The physical method mainly refers to adding cyclodextrin and its derivatives to the spinning solution for spinning method, coating or printing method, s...
