Problems solved by technology

[0006] The object of the present invention is to aim at the defect that traditional cotton fiber is easy to wrinkle and deform, and provides a kind of anti-wrinkle modified cotton fiber and its preparation method, which uses apigenin, primary amine derivatives, paraformaldehyde, acid anhydride and cellulose As a raw material, a wrinkle-resistant modified cotton fiber material has been obtained through multi-step reactions such as Mannich reaction and esterification. While having high-efficiency wrinkle-resistance, it also has high-efficiency antibacterial properties and significantly improved mechanical properties. It is foreseeable that This material will usher in a broad market space, especially for the field of clothing

Embodiment 1

[0036] Step (1) Add 1 mol of apigenin (A), 3.3 mol of ethanolamine (B), and 6.6 mol of paraformaldehyde into 100 mol of 1,4-dioxane, heat to 90°C and stir for 20 hours, let stand, and distill under reduced pressure, Dissolve the concentrate in ethyl acetate, after cooling, add 1N sodium hydroxide aqueous solution to wash 3 times, deionized water wash 3 times, let stand to separate layers, separate liquids, take the organic phase and dry it with anhydrous sodium sulfate, filter , rotary evaporation, and vacuum drying to obtain intermediate product I (IR: 3343cm -1 : -OH exists; 1629cm -1 :-C=C-exists; 1581cm -1 、1472cm -1 、1441cm -1 : benzene ring exists; 1148cm -1 :-C-N-Generation; 937cm -1 : oxazine ring formation).

[0037] Step (2) Take the cotton fabric (C) and pad it in the aqueous solution of 15wt% succinic anhydride (D), 5wt% 4-dimethylaminopyridine, 5wt% sodium dihydrogen phosphate, bath ratio 20:1, soak for 1h , prebaked at 80°C for 5min, baked at 200°C for 2mi...

Abstract

The invention belongs to the field of new materials and relates to an anti-wrinkle modified cotton fiber and a preparation method thereof. The anti-wrinkle modified cotton fiber is obtained by takingapigenin, primary amine derivatives, paraformaldehyde, acid anhydride and cellulose as raw materials through multi-step reactions of a Mannich reaction and esterification. The anti-wrinkle modified cotton fiber material not only effectively solves the problems of easy wrinkling and easy deformation of the existing cotton fiber but also has the advantages that the high-efficiency antibacterial performance and the mechanical performance are obviously improved, and it is foreseeable that the material may meet wide market space and is particularly suitable for the field of clothing.

Description

technical field [0001] The invention relates to an anti-wrinkle modified cotton fiber and a preparation method thereof. The invention belongs to the field of new materials. Background technique [0002] Cotton fiber fabric is very suitable for clothing fabrics due to its good moisture absorption and breathability. But there is the deficiency that it is easy to wrinkle after washing, and it is very impractical to iron cotton clothes every day. In order to overcome the easy wrinkle of cotton clothing, many domestic research institutions regard the anti-wrinkle technology of pure cotton fabric as a research topic. Non-iron anti-wrinkle treatment process is also called durable calendering or permanent setting finishing. After finishing with resin, it can achieve the purpose of anti-wrinkle, anti-shrinkage and durable setting, and endow the fabric with comfortable and soft characteristics. [0003] Cotton fiber is a natural polysaccharide cellulose fiber. Cellulose is compose...
