Embodiment 1

[0018] Put a 500mL beaker containing 200mL of 10% sucrose aqueous solution in a constant temperature water bath, the temperature of the constant temperature water bath is 20°C, slowly add 45g of epichlorohydrin, 0.2g of tetrabutylammonium bromide, and 19.5g of sodium hydroxide , mechanically stirred; after the epichlorohydrin was added dropwise, the temperature rose to 35°C, and the reaction was stirred at a constant temperature for 4 hours, and then a small amount of excess sodium hydroxide in the reaction solution was neutralized with sulfuric acid to obtain sucrose glycidyl ether.

Embodiment 2

[0020] Put the 500mL beaker containing 300mL mass percentage concentration of 10% sucrose aqueous solution into a constant temperature water bath, the temperature of the constant temperature water bath is 20°C, slowly add 68g epichlorohydrin, 0.3g tetrabutylammonium bromide, 30g sodium hydroxide, Stir mechanically; after the epichlorohydrin is added dropwise, the temperature rises to 35°C, and the reaction is stirred at a constant temperature for 4 hours, and then a small amount of excess sodium hydroxide in the reaction solution is neutralized with sulfuric acid to obtain sucrose glycidyl ether.

Embodiment 3

[0022] A 500mL beaker containing 350mL of 10% sucrose aqueous solution was put into a constant temperature water bath, the temperature of the constant temperature water bath was 25°C, slowly added 78g of epichlorohydrin, 0.37g of tetrabutylammonium bromide, and 35g of sodium hydroxide, Stir mechanically; after the epichlorohydrin is added dropwise, the temperature rises to 35°C, and the reaction is stirred at a constant temperature for 6 hours, and then a small amount of excess sodium hydroxide in the reaction solution is neutralized with sulfuric acid to obtain sucrose glycidyl ether.

Abstract

The invention provides a cross-linking agent and a crease finishing agent of sucrose glycidyl ether. The molecular formula of the cross-linking agent and the crease finishing agent of the sucrose glycidyl ether is C12+3nH22+4nO11+n, and the structure formula is C12H22O11(CH2CHCH2O)n, wherein n is between 2 and 8, namely each sucrose molecule contains 2 to 8 glycidyls; and the sucrose glycidyl ether cross-linking agent and the crease finishing agent are prepared from sucrose aqueous solution, epoxy chloropropane, tetrabutyl ammonium bromide, sodium hydroxide and other substances through series of processes. The sucrose glycidyl ether has excellent cross-linking and crease finishing effects, can be mixed with milk protein into solution to treat alkaline decrement orlon textile, and can graft the milk protein firmly on the textile. The cross-linking agent and the crease finishing agent and the synthesizing method can enable the fold elastic recovery angle of silk broadcloth to be raised from 220 degrees to 290-300 degrees, and have convenient application and low cost.

Description

technical field [0001] The invention relates to the technical field of textile engineering, in particular to a fabric grafting crosslinking agent, an anti-wrinkle finishing agent and a synthesis method thereof. Background technique [0002] In the field of textile engineering, cross-linking agents are often used, such as grafting proteins on other fibers, grafting functional compounds on fabrics, silk sericin fixation, etc., will use cross-linking agents. The commonly used cross-linking agent in China is glutaraldehyde, etc., and the cross-linking agent synthesized by polyoxyethylene ether is useful abroad. In the anti-wrinkle finishing of fabrics, 2D resins are commonly used. However, glutaraldehyde as a cross-linking agent can cause the fabric or fiber to turn yellow. Even if the cross-linking conditions are controlled so that the cross-linking does not turn yellow, it will still turn yellow in the subsequent washing process. 2D resin has a good anti-wrinkle finishing ef...
