Description
Technical field
The present invention relates to use with mylar (pet resin) as the so-called polyester line of raw material, polyester fiber, serviceability fiber with excellent such as good, the fine quality degree of intensity, DIMENSIONAL STABILITY are during as cloth, fibre, inevitable dyeing processing is become before unexistent easy technology.In addition, the invention still further relates to the polyester fiber that makes very useful original dyeing difficulty and become more firmly and cost and cost of equipment are increased, discarded object and water consumption be the technology of the requirement in considerably less response environmental protection epoch also.
Background technology
Sneaked into dyestuff and pigment in feed stage mylar in the past, the technology that is woven into line after painted is well-known.(patent documentation 1)
In addition, to being spun into the stage behind the line and even being woven into after textiles or the braided fabric with this line, the technology with disperse dyeing under the environment of High Temperature High Pressure is also well-known.(patent documentation 2)
Further; add pigment or dyestuff with high composite rate in the low mylar of temperature toward dissolving in advance; after the granulating as masterbatch; join as in main raw-material other mylar by certain blending ratio, guarantee that dyestuff and pigment disperse as early as possible and the inhomogeneity technology that dyes is also well-known.(patent documentation 3)
In addition, in dyestuff, add positive charge, also known by everybody to the staining technique of the so-called cation stain of passing through electric combination that is colored line adding negative electrical charge.(patent documentation 4)
; polyester fiber in the past has following problem, with the same as the fiber of main material with vistanex, with dye the difficulty mylar as raw material; with the inadequate so-called albefaction of dyeing that prior art can produce polyester fiber, see there is not white gloss from certain angle.Particularly in the black that heavy colour is transferred, this phenomenon is special to be become significantly.

Though the colouring method of polyester fiber is through the many researchs of ancestor and improvement, and as the synthetic fiber that are not natural fabric, the generality in its world has obtained the support of many producers and consumers aspect cost and rerum natura, but its colouring method still has several problems.Therefore, the inventor attempts further improving the raw material dye technology on the basis of the initial investment of considering color emissivity, cost, great number, a large amount of carrying capacities of environment such as water for industrial use, formed the present invention.
Now, general utilizes in the dyeing of DISPERSE DYES under High Temperature High Pressure, and the unsafty problem of color emissivity is arranged.Also has such destiny, if with dyestuff the polyester line dyeing that albefaction characteristic arranged high to the refractive index of light, even dyestuff self has color, because the transparency of dyestuff, come if light shines from the angle at the high polyester place of the refractive index of light, color can not be reflected to the there.Heavy colour such as black particularly, such negative effect is obvious.
Utilization is doomed to have the dyeing of the dyestuff of albinism, even with the painted effective and electricity that can realize very thin color in conjunction with the cation stain of making mechanism, can not solve same problem.
In addition, make pigment adsorption on masterbatch, be coupled to by a certain percentage in the mylar as main material, attempt the painted technology of raw material, though improve dispersing of pigments and just can realize stable color by small amounts of pigment, operation and the necessary cost cost of making masterbatch earlier must be arranged.
The size of the pigment that uses in the polyester raw material dye technology that utilizes pigment that prior art adopts is probably at 2 microns or smaller slightly again.
Itself does not have the transparency pigment, can shading, therefore can solve the problem of the albinism that causes that dyeing has, but problem is arranged uniform aspect dispersed, existing problems aspect the repeatability of color, and color difference as requested is by weight high pigment composite rate that need from 5 to 40.
Even the polyethylene terephthalate for one of representative raw material of polyester line, pigment also is foreign matter, and the incorporation rate of foreign matter is more high, the original physical property of the polyester line that is formed by polyethylene terephthalate is just more destroyed, be difficult to make thinner line, namely enable to work it out, also can stay the problem of undercapacity.
Summary of the invention
Therefore, in order to solve the dyeing that utilizes above-mentioned dyestuff or the painted problem that has of raw material of dyestuff and even pigment, simultaneously in order to realize color of object, the inventor has developed composite rate can raw material pigmented polyester line still less, that utilize pigment.
Initial pigment is water insoluble or the inorganic matter of coloured finely particulate of solvent or organic compound, mixes the back for covering with paint, lacquer, colour wash, etc. the colouring of curtain or shaping thing with vehicles, and dyestuff should be different from the pigment of water-soluble or solvent generally speaking.
What use among the present invention is pigment, the yellow iron oxide of chromatic colour pigment for example, and titan yellow, red iron oxide, ultramarine, dark purple, cobalt ultramarine, dish redness, calcium sulfide etc.; Carbon black is also for example arranged, blacklead, iron oxide black, fluorescent pigment, the metal powder of aluminium or bronze etc.
In addition, it is good to be allowed to the colouring agent that uses as food additives, namely use this colouring agent by prior art to the dyeing of polyester line, also can only obtain not dying or the wash resistant low product of firmness of rub resistance not.
But if technology of the present invention, for direct and Food Contact and even preservation, the cloth of the safety that the polyester line constitutes and sack etc. also can use.
Nanometer degree about pigment or colouring agent is pulverized, though pulverize and to access by explosion, but better for the big or small homogenization, the size distribution that further make particle, the star crushing mill ZRS(Ashizawa Finetech ltd. system of utilizing has been arranged) method.
The granularity of the pigment of pulverizing preferably in 10nm～100nm scope, and does not worry that size distribution is big in the scope of 5nm～5000nm substantially, and it is neat especially.
In addition, when adding in the mylar by powdered to the pigment of nanometer degree, composite rate is enough at 0.2～3 weight %, more preferably at 0.25～2.5 weight %.Even pigment, is crushed to pigment or the colouring agent of 10～100nm degree not by masterbatchization, under astonishing so low composite rate, also can realize impartial fast dispersion.
The temperature of the mylar when pigment is sneaked into, the same when making common polyester line, the degree at 200 ℃～400 ℃ there is no need to set special temperature.The shape of the ozzle when spinning (spinning oral pore) is not only circle, and Y-shaped, W font, so-called special-shaped section line such as star-like also can be made.
Use polyester raw material coloring line of the present invention, solved the problem as the dyeing difficulty of negative characteristic that is had by mylar, just can dye gay colours with considerably less pigment or colouring matter, and the high line of firmness can be provided and use these lines and textiles or clothes such as braided fabric, nonwoven fabric.
In addition, compare with the high pressure dyeing with DISPERSE DYES, not only initial stage equipment is very cheaply easy, and water for industrial use can be significantly saved in the requirement in seasonable generation, and can significantly cut down the load that industrial water drainage causes environment.
The specific embodiment
Here, in order to be described in more detail the present invention, give one example.
Under 200 ℃～400 ℃ temperature, polyethylene terephthalate is dissolved with the spiral extruder that dissolves, one side is added the carbon black that is crushed to 10～100nm with feed screw light weight ground with metering by 2.3 weight %, one in the face of dividing by 400g/ from the circle cross section lines that the metal mouth spues that spin, the position of 4cm below the metal mouth, tempering air with 25 ℃ to 28 ℃ blows, and obtains not extension line.At this time can find, in the polyethylene terephthalate that has dissolved carbon black, evenly disperse very fast.
With 2 sections warm water extension methods of 50 ℃/90 ℃ the not extension line that obtains being elongated to 2.0～2.5 times subsequently, is that the polyester line of dying black of 1.5 DENIER obtains tow with fiber number.
It is long impartial to described tow cut-out to press 3.8mm, obtain the black polyester fiber, put it on the carding machine and carry out sliverization, obtaining yarn count is the polyester line of the painted spinning of raw material about 40, these twisting at heads 500 times of spinning, weave into fawn with the knit wear knitting machine and compile (inside and outside crisscross, as to make the braid method of fawn apperance).
The fiber number homogeneity of the black polyester long fiber line after raw material is painted is no problem, and it is very outstanding that the fawn of weaving into the spun line of the black fiber of staple fibreization is compiled the friction firmness of cloth, can reach 4～5 grades.
In addition, this fawn cloth does not have specking and the color spot of so-called scratching or damage above being, is A rank product as cloth.
Utilize possibility on the industry
Little pigment that is crushed to 10～100 nanometer sizes or colouring agent and those normally used sizes different, it is dispersed fast not only to show equalization, and just can produce sufficient coloring effect with considerably less amount.
Not only do not need special equipment, with easy more equipment, do not need special temperature conditions and environment set just can provide firmness high polyester long fiber and polyester staple fiber.
In a word, a kind of fiber can be provided, carry out super amount production with heavy equipment and make the polyester line that the polyester line of homogeneous, the existing poststaining of wishing to reduce cost are used for those, do not need its poststaining devices needed and operation now, just can make the fastness height and not only prevent albefaction, wastewater flow rate is also significantly saved, and industrial water drainage is significantly reduced the load that environment produces, and conforms with the ecology that current era requires.
In addition, this part thing of simple equipments has remedied in the fiber industry of the color unanimity that requires colorful color raw material pigmented polyester line and must produce and be created in two kinds of existing weakness of storehouse loss in a large number.
