The more preferable functional fiber of bacterium performance.
In a preferred embodiment, the concentration of hydrophilic high molecular material is 14 in the component A spinning solution
~20wt%；Organic concentration into fine high molecular polymer is 28~32wt% in the B component spinning solution；The coagulating bath
For the mixture of aqueous sodium persulfate solution, hydrochloric acid and dimethyl sulfoxide (DMSO)；In the coagulating bath dimethyl sulfoxide (DMSO) content be 0~
50wt%, the temperature of coagulating bath is 30~35 DEG C, and pH value is 2~5.
Antibacterial functionalized fiber in the present invention, the component A spinning solution of sandwich layer is formed in aqueous sodium persulfate solution and dilute salt
Setting rate in acid is slow relative to the setting rate of the B component spinning solution of cortex, can so influence the coagulation forming of fiber,
Its mechanical behavior, stability are influenceed, or even influences its antibacterial action, it is therefore desirable to adds the B component spinning of a certain amount of cortex
The solvent of stoste regulates and controls the setting rate of cortex, reaches cortex and sandwich layer setting rate is consistent substantially, and with relatively more slow
The speed coagulation forming of sum.In addition, the inventors discovered that want to form diameter than more uniform in fiber surface, with sandwich layer phase
Aperture even must adjust its pH value into acidity when spinning solution is in solidification, make spinning solution anti-while coagulation forming
The filler in scaling layer is answered, forms aperture, it is impossible to consuming filler in fibrocortex table through overpickling after fibre solidification
Face forms aperture, and otherwise the acid in coagulating bath can only be reacted with the filler on fibrocortex surface, and shrinkage pool is formed on cortex,
It can not be connected with sandwich layer, influence the restraining and sterilizing bacteria effect of fiber, be additionally, since the content of solvent in cortex and sandwich layer spinning solution
It is different with from the caloic exchange velocity of coagulating bath, cause sandwich layer not enough fully to solidify, influence the stability of fiber really and follow-up
Processing characteristics.
In addition, the pH value of coagulating bath is unsuitable too high, otherwise the reaction between the acid and filler in coagulating bath is excessively violent, produces
Gas support the diameter of big aperture, cause the silver particles in sandwich layer to pass through aperture and be lost in, while also influence fibre spinning
Mass and heat transfer and stable solidification shaping of the stoste in coagulating bath.Certain coagulating bath pH value can not be too big, otherwise filler not by
Consumption completely, caused hole is few, some its restraining and sterilizing bacteria effects.Secondly, in order to obtain penetrating the aperture of cortex, it is necessary to which spinning is former
Liquid slow solidification in coagulating bath, so needing the coagulating basin of enough length, make stop of the spinning solution in coagulating bath enough
The long time, solvent is higher in residence time short then as-spun fibre, can be broken when posterior drawing, can also make
The bore deformation that is formed on cortex and block, influence last performance.
