Description
Technical field
The present invention relates to acetate fiber spinning fields, and in particular to acetate fiber crimp pretreatment unit, pretreatment fluid and
Preprocess method.
Background technology
Acetate fiber curly course is particularly significant, has vital influence to its performance and application.On the one hand, it crimps
Acetate fiber is set to obtain more bigger serface, better Adsorption Filtration Properties, higher filtering rod；On the other hand, it crimps again
So that fiber surface is formed curling damage by strong friction and shearing, negative shadow is generated to its physical property and subsequent use
It rings；Importantly, for the acetate silk higher to single-strand, imappropriate pretreatment, technology almost without
Method is implemented.Tart flavour and to go mouldy be the phenomenon that acetate fiber another kind is easy to happen, although can be added such as in spinning oil
The bacteriostatic agent of hydrogen peroxide etc, but tend not to thorough solve the problems, such as.Diacetate fiber slice itself carries certain tart flavour, certain
A little sharp-nosed people dislike this taste.If tow tart flavour can be removed, user welcomes very much.In addition the vinegar after crimping
Sour fibre bundle needs by technical process, the adjustings of tow cluster performance such as drying, pendulum wire, packings to help that silk ribbon is overcome to transport
The problems such as diverging that row generates in the process, curling round the roll, silk ribbon be wide, electrostatic.Silk ribbon pretreatment appropriate, can help to solve or change
The above many disadvantages of kind acetate fiber, are a kind of novel technical finesse means.
The usually used technology of dry spinning process is fairly simple, and the upper silk ribbon for crossing finish is sent into crimping machine and completes work
Skill route, for the strand specification that certain curling modulus are larger, this simple way is inappropriate, and such curling is unstable
Fixed, rebound is big, and curling wave is not secured enough, and tow specific surface area is not big enough, silk ribbon poor appearance, and technique, which is not achieved, in crimp energy wants
It asks.It, completely can be to avoid the above problem by appropriately pre-processing.On the other hand, we attempt and compare other reduction curlings
The method of modulus, if steam sprays, steam sprays or is also easy to produce condensation water slug because steam flow is small, causes spray vapour uneven
It is even, or because of steam flow generation overtemperature bigger than normal, to cause tow quality unstable.
Invention content
A kind of acetate fiber curling pretreatment unit of present invention offer, pretreatment fluid and preprocess method, acid is removed to obtain
Taste reduces curling modulus, softening tow, reduces curling damage, antibacterial and mouldproof, adjusts the multipurposes such as silk ribbon cluster performance.
The present invention is realized using such technical solution：A kind of acetate fiber curling pretreatment unit, including pretreatment
Flow container, bottom are connected to spraying system by pipeline through flowmeter, and spraying system includes that spraying babinet and nozzle, nozzle are also connected with
There is compressed air pipe；Pending acetate silk is through spraying babinet；It is additionally provided with temperature sensor in pretreatment flow container
And electric heating tube, temperature sensor and electric heating tube are all connected to temperature controller.
Further, it is set in spray tank body there are two nozzle, is mounted on spraying babinet acetate silk approaching side, position
In acetate silk upper and lower.
Further, compressed air pipe is equipped with pressure regulator valve.
Further, the pretreatment flow container is located at a high position, and spray tank body is located at low level.
Further, it is equipped with ball-cock assembly above pretreatment flow container.
The invention further relates to acetate fibers to crimp pretreatment fluid, based on mass concentration, wherein selective plasticization agent as needed
For in 2-5%, spinning oil 1-3%, alkali 10-50ppm, oil film reinforcing agent 100-500ppm, bacteriostatic agent 50-500ppm one kind or
Person is several, remaining is deionized water.
Water itself has cooling and lubrication function, can effectively prevent tow vitrifying in curling；Other additives can
To need to accept or reject according to different, can also use simultaneously；For example：When producing the higher tow of single fiber line density, it can add
Plasticizer；When the free acid of raw material is higher, alkali can be added；When needing to be improved an appearance or coherent, spinning can be added
Finish and oil film reinforcing agent；Tow sells to high temperature and humidity at area or across plum rain season storage period, can add bacteriostatic agent.
Further, the plasticizer is acetone, and alkali is food-grade sodium carbonate, and oil film reinforcing agent is alkyl-blocked random
Polyethers, bacteriostatic agent are Nepal's gold esters food grade additives.
The invention further relates to acetate fibers to crimp preprocess method, before acetate fiber curling, by atomization system, by vinegar
Sour fiber crimp pretreatment fluid atomization, is injected on acetate fiber, is fully soaked before so that acetate fiber is entered crimping machine.
Further, the spray particle diameter of the atomization system is 100 μm, and the temperature of spraying liquid is controlled at 35-65 DEG C.
Further, the atomization system is processed into stable haze, atomization quantity 10-60ml/ by pretreatment fluid is crimped
min。
It is controlled and stablize to form temperature, granularity and spray amount by atomization system for pretreatment unit in the present invention
Atomization air flow is accurately injected on acetate fiber, and haze is formed around tow, before so that acetate fiber is entered crimping machine fully
Wetting, possesses appropriate curling modulus, the temperature of stronger coiling-resistant toughness and uniform spinning oil coating and stabilization.
Plasticizer is added in pretreatment fluid, curling modulus can be reduced；Alkali is added can also mitigate for adjusting pH value
Tart flavour, the softening tow of acetate silk；Oil film reinforcing agent is added, curling damage can be mitigated；And bacteriostatic agent is added, it can be with
It prevents from going mouldy；Spinning oil is added, cluster performance can be adjusted, particularly with the addition of the spinning oil in patent 201610151069.3
Agent.In preferred scheme, select acetone as plasticizer in pretreatment fluid, since acetone is the solvent of acetate fiber spinning, energy
Cellulose acetate is dissolved, the present invention, by tow surface slightly soluble, makes tow acquisition preferably crimp tough using the acetone of concentration 2-5%
Property, and when reducing tow crimping surface chap.
The invention has the advantages that：
1）Acetate fiber crimps modulus and reduces, and crimping difficult kind curling quality originally improves；
2）Acetate fiber appearance enhancement after curling：Curling, shaping is good, and curling wave is uniform, and curling, shaping is secured；
3）Acetate fiber tart flavour is reduced；
4）Acetate fiber curling damage reduces；
5）Acetate fiber anti-mildew ability enhancing for a long time.
