Abstract
The present invention relates to synthetic fibers fields, specifically disclose a kind of preparation method of modified polyester fiber silk.It is characterized by: being heat-treated to polyester fiber silk.The heat treatment, at 100-180 DEG C, the time was controlled at 10-30 minutes for temperature control.Obtained modified polyester fiber silk has the characteristics that elongation at break is low, is unlikely to deform, which is made modified polyester fiber cloth through weaving and is exclusively used in reclaiming fields from the sea, effect of reclaiming fields from the sea is good, at low cost.
Description
Technical field
The invention belongs to synthetic fibers fields, and in particular to a kind of preparation method of modified polyester fiber silk.
Background technique
Polyester fiber is commonly called as " terylene ".It is the polyester as made of organic dibasic acid and dihydric alcohol polycondensation through the resulting conjunction of spinning
At fiber, abbreviation PET fiber invents in nineteen forty-one, is the first big kind of current synthetic fibers.It has excellent resistance to wrinkle
Property, elasticity and dimensional stability, good electrical insulation capability, resistance to daylight, rub resistance be not mould not eat into, preferable chemical-resistant reagent
Performance, can weak acid resistant and weak base.But its non-hygroscopic, non-refractory, elongation at break are also larger.
Polyester fiber silk is for manufacturing polyester fiber cloth.It is right for reclaiming fields from the sea after stone being embraced with polyester fiber cloth
The requirement of polyester fiber cloth is to be not easy to deform, so having higher requirement, extension at break to the elongation at break of polyester fiber
The lower rate the better.
The commodity factory elongation at break of polyester fiber silk is greater than 12% at present, polyester fiber cloth bag made of this fiber
Wrap up in put into after building stones it is marine after, since the deformation rate of polyester fiber cloth is big, be easy to cause falling off for stone, rush stone by seawater
It walks, influences the effect reclaimed fields from the sea, increase cost of reclaiming fields from the sea.
Summary of the invention
The technical problems to be solved by the present invention are: generally existing for polyester fiber cloth used of reclaiming fields from the sea at present
The defects of elongation at break is high, easily-deformable, causes the effect reclaimed fields from the sea poor, at high cost and deficiency, provide a kind of modified poly ester
Filametntary preparation method.The modified polyester fiber silk obtained using the preparation method is with elongation at break is low, is unlikely to deform
The features such as, which is made modified polyester fiber cloth through weaving and is exclusively used in reclaiming fields from the sea, effect of reclaiming fields from the sea
It is good, at low cost.
The present invention adopts the following technical scheme that, Lai Shixian goal of the invention.
A kind of preparation method of modified polyester fiber silk, is heat-treated polyester fiber silk.
Outsourcing polyester fiber by flow orientation and stretching due to being orientated in process of production, therefore the inside of polyester fiber is big
Strand has than stronger orientation effect, although polyester fiber original production producer can also take heat treatment process, often leads
Syllabus is to strengthen its mechanical property, and to reducing, elongation at break concern is inadequate.We, which develop, carries out outsourcing polyester fiber
Suitable heat treatment temperature and heat treatment time, purpose are exactly to make its extension at break under the premise of not influencing its mechanical property
Rate reduces, and further heat treatment can increase the mobility of fiber molecule, changes the internal structure of fiber.When temperature is lower at heat
Reason, fiber can be shunk under its effect, and some little crystallizations are melted at this time, therefore compared with before heat treatment, fiber
Strength has enhancing.And when heat treatment temperature gradually increases, the contraction of fiber is gradually increased, this increases fibrous inside
Stress, additionally since the exercise effect of amorphous region strand, intrastitial macromolecular orientation can decline gradually, this makes fiber
Elongation percentage decline.Therefore suitable heat treatment time and heat treatment temperature, the fiber after Overheating Treatment can be made, segment occurs
It curls, so that its elongation at break of polyester fiber lowers in use process, fracture strength increases.
The heat treatment, at 100-180 DEG C, the time was controlled at 10-30 minutes for temperature control.
Further, the heat treatment, at 140 DEG C, the time was controlled at 20 minutes for temperature control.
The heat treatment, Equipment for Heating Processing are industrial oven.
The polyester fiber silk forms polyester by organic dibasic acid and dihydric alcohol polycondensation, obtains through spinning.
Further, the binary acid is terephthalic acid (TPA).The dihydric alcohol is ethylene glycol.
Modified polyester fiber cloth is made for weaving in the modified polyester fiber silk, and the modified polyester fiber cloth is used
In reclaiming fields from the sea.
The utility model has the advantages that
The modified polyester fiber silk obtained using the preparation method has the characteristics that elongation at break is low, is unlikely to deform, will
The modified polyester fiber silk is made modified polyester fiber cloth through weaving and is exclusively used in reclaiming fields from the sea, due to the modified polyester fiber cloth
Deformation rate is small, after package building stones investment is marine, it is not easy to cause falling off for stone, so that stone is not easy to be washed away by seawater, enclose
It is good, at low cost that ground effect is made in sea.
