Description
Technical field
The present invention relates to differential chemical fibre technical field, specifically a kind of ice-cold rapid-curing cutback hydrophilic polyesters fiber and its processing side
Method.
Background technology
Nice and cool property textile fabric is always a direction of chemical fibre worker research, originally by changing fibre section come real
The ventilative of existing fiber, rapid-drying properties, later in order to improve the hydrophily of polyester, many researchers by adding the in the polyester
3rd, the 4th monomer develops hydrophilically modified polyester.In recent years, it is poly- to strengthen by adding mica, jade powder in the polyester
The heat conductivity of ester is so as to improve the nice and cool characteristic of polyester fiber.With the change of consumption idea, people want to summer clothes
Ask in addition to fashionable appearance, more focus on clothes in cool and comfortable.Normal polyester（PET）Fiber is used as production in conjunction fibre
Maximum kind is measured, favors although it obtains people with uncomplicated laundering, quick-drying, well-pressed advantage, also because its hygroscopicity is poor, uses it
The clothes being made not absorbing sweat when wearing, has the shortcomings that feeling of oppression and heat allows people to feel put about, while the official regain of normal polyester is only
Have in 0.4%, fiber that water content is very low, be unfavorable for heat absorption.
The content of the invention
The problem of to solve polyester fiber hygroscopicity, the heat absorptivity difference at present with nice and cool characteristic, the present invention provides a kind of
Ice-cold rapid-curing cutback hydrophilic polyesters fiber and its processing method, the polyester fiber have a good hygroscopicity, and excellent moisture, steam are defeated
The property sent, can quick conductive heat sink, uvioresistant, rich in trace element and amino acid.
The present invention is achieved by the following technical solutions：A kind of fibre section of ice-cold rapid-curing cutback hydrophilic polyesters fiber is ten
Font, fracture strength 2.8-4.0cN/dtex, extension at break 18-30% contain jade, pearl powder.
Fibre section is conducive to conveying steam to be cross, and radiating of breathing freely makes skin keep dry and comfortable.Fiber keeps rational
Fracture strength and extension at break, are conducive to follow-up weaving and use.
The preparation method of described ice-cold rapid-curing cutback hydrophilic polyesters fiber is following steps：
（1）Prepare the ice-cold master batch of hydrophilic polyesters：Ice-cold master batch is made in hydrophilic polyesters, jade powder, pearl powder and auxiliary agent, its
In, hydrophilic polyesters, jade powder, the mass ratio of pearl powder and auxiliary agent are 70-80：10-15：10-15：1-3；Powder in master batch
Content is unsuitable too high, otherwise influences powder scattered in master batch, so as to influence the spinnability of master batch.Jade and the ratio of pearl
Control as far as possible in suitable quantity, otherwise the more difficult good embodiment of effect.Auxiliary agent is primarily to powder is preferable in master batch
It is scattered.
Preferably, the average grain diameter 100-300nm of jade powder, pearl powder, auxiliary agent is selected from higher fatty acid salt, it is excellent
Elect higher fatty acids magnesium salts or higher fatty acids calcium salt as.The larger blocking filtering device of particle diameter, smaller easy reunion, disperses tired
It is difficult；Higher fatty acid salt be conducive to jade powder, pearl powder it is scattered.
Jade is that jade sense of touch is ice-cold, rich in trace element because it has natural nice and cool, healthcare function.Pearl
It is the ice-cold natural material of sense of touch, containing abundant amino acid, there is good health-care effect to skin, while both powder
Main component all there is quick conducting power and preferable uvioresistant function.
Master batch is prepared using conventional method：Raw material is weighed, matched, mixing, by mono-/bis-Screw Extrusion, cooling, pelletizing.
（2）Ice-cold master batch and hydrophilic polyesters are subjected to co-blended spinning；
Preferably, the mass ratio of ice-cold master batch and hydrophilic polyesters is 4-8：92-96, controls the content of powder to be in the fibre
0.8% ~ 1.5%, too high powder content can cause difficulty in spinning.
The technology characteristics of co-blended spinning are that spinning body temperature is 270-285 DEG C, fondant filter precision 15-45um.By
It is relatively low in hydrophilic polyesters fusing point, so spinning temperature is conducive to preventing the amino acid degradation in pearl powder without too high.Rationally
Filter Precision facilitate filtering out large granular impurity in master batch, if but Filter Precision is too high, filter can be caused more
Change too frequently, influence stability of spinning process.
Preferably, step（1）With step（2）230-245 DEG C of the fusing point of described hydrophilic polyesters, inherent viscosity η is
0.60-0.68dl/g, official regain is more than 1.2%, and the fusing point of hydrophilic polyesters is unsuitable too high, and too high fusing point easily makes pearl
Amino acid in powder is degraded in spinning process；Fusing point and inherent viscosity can not be too low, too low fusing point, inherent viscosity meeting
The spinnability of new waterborne polyester is set to be deteriorated, physical index is deteriorated, so as to influence spinning processing stability to be used with subsequently woven.
（3）After being sprayed through spinneret, then through cooling, drawing-off, sizing, ice-cold rapid-curing cutback hydrophilic polyesters fiber is prepared into.
The spray orifice of spinneret is cross, and spinning speed is 4000-5000m/min, draw ratio 2.0-2.8, setting temperature
100-130℃.Be conducive to preparing the fiber of cross section using the spinneret of cross spinneret orifice, rational spinning speed,
Draw ratio, setting temperature, are conducive to obtaining the qualified fiber product of performance.
The aqueous of the hydrophilic polyesters of the present invention is more than 3 times of normal polyester, is more beneficial for absorbing the heat that human body is distributed,
Make fiber more cool and comfortable.Simultaneously because hydrophilic polyesters have passed through a large amount of modifications, the regular molecular chain structure of polyester is destroyed,
Therefore hydrophilic polyesters have dyeability under ordinary pressure, can save follow-up dyeing expense, and widened the application of fiber.The present invention
Fiber can be widely used for the summer clothes articles for use such as summer sleeping mat, seat cushion.
Compared with prior art, the beneficial effects of the invention are as follows：
（1）The cool fiber prepared using hydrophilic polyesters has good hygroscopicity, and endothermic effect is good, and has dyeing at normal pressure concurrently,
Electrostatic-proof function；
（2）Jade, pearl powder collaboration hydrophilic polyesters realize high-efficiency heat conduction, heat absorption, and fiber cross section realizes ventilative radiating；
（3）Hydrophilic polyesters are more suitable for carrying out co-blended spinning with pearl powder than normal polyester, and lower spinning temperature can effectively press down
Only in pearl powder amino acid degraded；
（4）Have jade and the healthcare function of pearl concurrently.
