Matter.But these compounds have safety issue in itself, can also be produced in the production process of prepare compound with certain poison
The accessory substance of property, this method do not meet current ecological spinning, the trend of Green Development, and to the physical and mechanical properties meeting of fabric
Cause necessarily to influence.
The content of the invention
The invention aims to provide a kind of hydrophobically modified method of bafta, deposited with solving the above-mentioned of prior art
The problem of.This method polymerize shape by lipase-catalyzed ethyl glutarate, propylene-glycol diacetate monomer in fabric face
Into long chain fatty acids, hydrophobically modified is carried out to bafta, does not have fluorine-containing, silicon-containing compound to participate in production process, also without poison
Property accessory substance generation, the physical and mechanical properties of fabric is not also influenceed, is a kind of brand-new, biological, environmentally friendly
Bafta hydrophobic finishing method.
The purpose of the present invention is achieved through the following technical solutions.
A kind of hydrophobically modified method of bafta, its step are as follows：
(1) first ethyl glutarate, propylene-glycol diacetate reagent are well mixed with liquid fat enzyme, obtain reaction examination
Agent and the mixed liquor of lipase；Described lipase content is the 30%-60% (v/v) of reagent；
(2) mixed liquor is uniformly put and be coated onto on bafta, obtained fabric is placed in thermostat water bath, carry out hydrophobic change
Property processing；
(3) by after processing fabric take out, wash several times with chloroform soln, wash away remaining reaction reagent and
Enzyme, the bafta with hydrophobic performance is obtained after naturally dry.
In step (1), described ethyl glutarate, propylene-glycol diacetate reagent mol ratio are scope 1:2-2:1, examination
Dosage is launched according to gross mass for the 150%-220% (mg/mg) of fabric quality.
In step (2), at 30-60 DEG C, the control of hydrophobically modified processing time exists the temperature control of described thermostat water bath
5-9h。
In step (3), after fabric hydrophobically modified processing terminates, three times fabrics are washed using chloroform soln.
The critical process of the inventive method is to utilize lipase-catalyzed ethyl glutarate, propylene-glycol diacetate monomer
It polymerize to replace conventional hydrophobic method for sorting, hydrophobic finishing is carried out to fabric again after first reagent is well mixed with enzyme.The present invention
Another critical process of method is described hydrophobically modified handling process, the temperature control of hydrophobically modified processing at 30-60 DEG C, when
Between control in 5-9h.
Described lipase-catalyzed bafta hydrophobically modified handling process principle is：Lipase is a kind of ester linkage hydrolyzing enzyme,
, can be with catalyzed transesterification under water-less environment, the synthesis for polymer.Pass through lipase-catalyzed glutaric acid diethyl
Ester, propylene-glycol diacetate monomer polymerize to form long chain fatty acids in fabric face, so that fabric obtains hydrophobicity.
The inventive method is suitable for handling bafta.The source category of liquid fat enzyme in the present invention is unlimited.
The beneficial effects of the invention are as follows：Polymerisation is occurred by lipase-catalyzed two kinds of di esters monomers, to bafta
Hydrophobic finishing is carried out, the hydrophobicity of bafta can both be improved, and environment will not also be polluted, while also will not shadow
Ring the physical and mechanical properties of fabric.It is a kind of brand-new, biological, green to carry out hydrophobically modified to bafta by lipase
, environmentally friendly bafta hydrophobic finishing new tool.
