Abstract
The present 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 DEG to 290-300 DEG, and have convenient application and low cost.
Description
Technical field
The present invention relates to the textile process technical field, particularly relate to agent of a kind of fabric graft crosslinking and crease-shedding finishing agent and synthetic method thereof.
Background technology
In the textile process field, often can use linking agent, as on the fiber that protein is grafted on other, will have that functional compound is grafted on the fabric, silk silk gum set or the like, all can use linking agent.Domestic linking agent commonly used has glutaraldehyde etc., external useful Soxylat A 25-7 synthetic linking agent or the like.In the anti-crease finishing of fabric, 2D resin commonly used etc.But glutaraldehyde can make fabric or fiber flavescence as linking agent, makes not yellowing when crosslinked even control crosslinked condition, but still can yellowing in washing process afterwards.The 2D resin has good anti-crease finishing effect as the crease-shedding finishing agent of fabric, and still, the fabric after the arrangement can slow release formaldehyde.Up to the present, still there is not research report about the linking agent that has crosslinked function and good anti-crease finishing function simultaneously concurrently.
Therefore, the exploitation synthesizing new, have good cross-linking effect, good crease-resistant finishing effect, cheapness, the linking agent of release formaldehyde does not have extraordinary application prospect.
Summary of the invention
The object of the present invention is to provide a kind of novel linking agent and synthetic method thereof.This novel linking agent had not only had crosslinked function, but also had had good anti-crease finishing function.
The molecular formula of sucrose glycidyl ether linking agent of the present invention, crease-shedding finishing agent is: C
12+3nH
22+4nO
11+n, structural formula is: C
12H
22 -nO

2O) n, 2～8 epoxypropyl are promptly contained in n=2～8 in each sucrose molecules.Sucrose glycidyl ether is a kind of solid matter, and white is water-soluble very good, can be mixed with very high concentration, decompose before dissolving reaching.
What wherein effect was best is sucrose glycidyl ether 100%.All hydroxyls have all been connected epoxypropyl in the 100% expression sucrose molecules, and promptly this linking agent has 8 epoxypropyl, is the linking agent that a kind of multi-active base is rolled into a ball, and is similar a bit with the ring texture of 2D resin.And more than the 2D of the functional group resin, can produce crosslinked action in all directions, and simultaneously, this linking agent is a kind of small molecules linking agent, good water solubility, and osmotic effect is good, thus have better crosslinked and anti-crease finishing effect, but do not produce formaldehyde.Can integrate cross-linked graft and anti-crease finishing function.
When having only part of hydroxyl to be connected epoxypropyl in the sucrose molecules,, also has crosslinked action as only containing 7,6,5,4,3 or 2 epoxypropyl in each sucrose molecules.
The present invention realizes by following steps:
With mass percent concentration is that 10～12% aqueous sucrose solution is put into water bath with thermostatic control, temperature is set in 20～25 ℃, slowly adds epoxy chloropropane then, adds Tetrabutyl amonium bromide simultaneously and makes phase-transfer catalyst, and in the adding sodium hydroxide and the hydrochloric acid that produces, mechanical stirring; After epoxy chloropropane had added, temperature was raised to 35 ℃, and kept constant, reacted 4～6 hours, used unnecessary small amounts of sodium hydroxide in the sulfuric acid neutralization reaction liquid then, promptly obtained sucrose glycidyl ether linking agent, crease-shedding finishing agent, wherein:
Sucrose is 1: 8.1～1: 8.5 with the ratio of the mole number of epoxy chloropropane in 10～12% the aqueous sucrose solution
10～12% aqueous sucrose solution is 1000mL: 1g～1000mL: 1.2g with the volume mass of Tetrabutyl amonium bromide ratio
Sucrose is 1: 8.1～1: 8.5 with the ratio of the mole number of sodium hydroxide in 10～12% the aqueous sucrose solution.
Epoxy chloropropane needs slowly to add, in order to avoid produce the temperature control phenomenon.
Experimental results show that:
Synthetic sucrose glycidyl ether linking agent is handled silk broadcloth, and the fold elastic recovery angle of silk broadcloth rises to 290 °～300 ° from 220 °.
Advantage of the present invention is: sucrose glycidyl ether has good crosslinked and anti-crease finishing effect, can not produce formaldehyde.The linking agent osmotic effect is good, and is water-soluble effective, and the synthetic sucrose glycidyl ether is mixed into solution with milk proteins, handles alkali decrement acrylic fabric, can be with milk proteins firmly on the grafting fabric.Can make the fold elastic recovery angle of silk broadcloth rise to 290 °～300 ° from 220 °.Simultaneously, it is convenient to use, and cost is low.
