Abstract
The invention discloses a kind of polyester fiber hydrophilic modifying method, belong to technical field of macromolecules, the pretreatment of sodium hydroxide solution agitating and heating will be added in polyester fiber, PET fiber surface is destroyed, is easy to later stage modification；Bromoethane solution, agitating and heating modification will be added in polyester fiber, then polyester fiber is added into the PVA solution that mass fraction is 4 5.5%, the polyester fiber after hydrophilic modifying is made in agitating and heating.Processing is modified to polyester fiber using bromoethane solution and PVA after the inventive method addition sodium hydroxide solution pretreatment polyester fiber, obtains hydrophily and the excellent polyester fiber of antistatic property；The inventive method is easy to operate, and reaction speed and reaction temperature are easily controllable, and course of reaction organic solvent addition is few, less toxic low stain low emission, and subsequent operation is easy, beneficial to industrialization promotion, has higher economic benefit.
Description
Technical field
The invention belongs to fiber preparation field, and in particular to a kind of polyester fiber hydrophilic modifying method.Terylene is poly- to benzene two
The trade name of the ester fiber of formic acid second two, it is one of three big main force's fibers in synthetic fibers.Because terylene linear macromolecule is pair
Title property benzene ring structure, good linearity and molecular chain structure stereoregular so that it is superior that it has that intensity is high, elasticity is good and rigidity is big etc.
Physical and mechanical properties, it is and stable to weak acid, alkali, there is excellent dimensional stability and good corrosion resistance, be one kind compared with
For preferable textile fabric, still, terylene is a kind of typical hydrophobic fibre, and only respectively there are a hydroxyl, nothing in its molecule both ends
Other hydrophilic radicals, molecular structure are in close-packed arrays, and crystallinity is high, and hygroscopicity is poor.(20 DEG C of relative humidity in normal conditions
65%), the hydroscopicity of terylene only has 0.4% or so (cotton 7-8%, polyamide fibre 4%, acrylic fibers 1-2%), in 100% relative humidity
Under the conditions of hydroscopicity be also only 0.6-0.8%.Therefore its hygroscopicity is poor, is also easy to produce electrostatic, easily stains, and influences its snugness of fit.
Endowing terylene fiber or fabric hydrophilic mainly have two methods：First, spinning is modified：In the spinning process of fiber
It is middle that Structure of PET Fiber is modified using the synthetic technology of fiber, make polyester fiber that there is hydrophilicity in itself, so as to change
Kind terylene wears performance；It is modified second, arranging：Mostly in fiber surface modification, reached using dacron afterfinish technology
Modified purpose.Hydrophilic radical is introduced on terylene macromolecular chain, fabric face is formed hydrophilic layer, so as to change fiber surface
Hydrophilicity.
Spinning, which is modified, refers to that during synthetic fibers current trend is to make so that polyester fiber has hydrophilicity
Polymer molecular structure hydrophiling, either introduce hydrophilic monomer or become the list of hydrophilic component after dyeing and finishing is processed
The different degrees of input industrialization such as body, heteromorphosis, microporous, compound house and the modification of graft of terylene structure
In production.The essence of chemical modification is to form one layer of hydrophilic compounds on the surface of polyester fiber or fabric, reaches and carries
The purpose of high microsteping surface hydrophilic performance, adoptable method mainly have a surface grafting polymerization of hydrophilic monomer, and hydrophily is whole
Manage the absorption set and some other processing of fiber surface of agent.
Hydrophilic radical graft copolymerization：The surface grafting polymerization of hydrophilic monomer be in terylene macromolecular introduce hydroxyl,
The hydrophilic radicals such as sulfonic group, ehter bond, so as to improve the hygroscopicity of polyester fiber, graft copolymerization mainly includes chemical graft and spoke
Grafting is penetrated, radiation grafting is better than chemical graft.Because terylene molecular chain structure has close packing ability and high crystallinity,
And there is no active group above macromolecular, graft copolymerization is mainly irradiated using initiator or energy beam, ultraviolet lamp,
Or using plasma performs etching processing to PET fiber surface so that fiber surface produces free radical, then using hydrophilic
Property monomer is graft-polymerized on free radical, so as to form the new superficial layer of water imbibition and antistatic behaviour, this method one
As equipment it is complicated, reaction speed is difficult to control, and has not yet to see industrialization report.
Chinese invention patent CN201410165074.0 provides a kind of methods of PVA to polyester fiber hydrophilic modifying, refers to
Mass fraction is used to pre-process 1h, solid-to-liquid ratio 1 for 3-10% sodium hydroxide solution polyester fiber:50, through rinsing and doing
Polyester fiber after dry is put into the reaction vessel for filling the PVA solution that mass fraction is 0.2-3%, and then reaction vessel is added
Enter by volume 3:2:1 acetic acid, methanol, sulfuric acid, acetic acid, methanol, the volume fraction of sulfuric acid are respectively 10%, then reaction is held
The mol ratio that device adds GA, GA and PVA that mass fraction is 25% is 1:4, the mechanic whirl-nett reaction 1-2h at 50-70 DEG C, instead
