Description
Technical field
The invention belongs to terylene field, and in particular to a kind of gel polyester fiber and preparation method thereof.
Background technology
Polyester fiber is an important kind in synthetic fibers, is the trade name of China's polyester fiber.It is with essence
Terephthalic acid (TPA) or dimethyl terephthalate (DMT) and ethylene glycol be raw material through esterification or ester exchange with prepared by polycondensation reaction into
Fine high polymer-polyethylene terephthalate, through fiber made of spinning and post processing.Polyester fiber is that three big synthesis are fine
The simplest one kind of technique, price are also relatively cheap in dimension.Along with it has, durable, elasticity is good, is unlikely to deform, corrosion resistant
The features such as losing, insulating, be well-pressed and quick-drying washable, is liked by people.The species of polyester fiber fabric is more, is washed except the system of knitting is pure
Outside synthetic fibre fabric, the product of also many and various textile fabric blend polyesters or intertexture, the deficiency of pure dacron is compensate for, sent out
Shoot and preferably play performance；
The preparation method of existing polyester fiber, typically using poly-succinic propylene glycol ester and PET resin blend spinning, so
Poly-succinic propylene glycol ester is degraded by the effect of biodegradable enzyme again afterwards and removed, to realize at the fine of polyester fiber
Reason.But the usual intensity of polyester fiber prepared by this method is relatively low, abrasion resistance properties are poor, and service life is short, from another point of view
