Cross-linking agent and crease finishing agent of sucrose glycidyl ether and synthesizing method thereof

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...

Problems solved by technology

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 effect as a fabric anti-wrinkle finishing agent, but the finished fabric will slowly release formaldehyde

So far, there is no research report on the cross-linking agent with both cross-linking function and good anti-wrinkle finishing function
