It is added to polypropylene raw materials during production. The improved large melt cavity spinning assembly is used to further control the process temperature to maintain the mechanical and physical properties of the raw materials. Then, the superfine denier antistatic fiber is obtained by spinning and stretching. The advantages of the fiber are: small monofilament fineness, good fabric style, good hand feeling, wearing performance and dimensional stability, and low production cost. Moreover, the process is stable and the operation is simple.
Description
The invention belongs to synthetic fiber---modification for polypropylene fiber Study on Technology development field.
Polypropylene fibre has advantages such as corrosion-resistant, anti-aging.But also there are a lot of shortcomings, make it be difficult to garment production.Its main cause be the single fiber degree too big (＞5D), just the single fiber fiber number is big.And fiber number is little or the ultrafine fiber is difficult to make.Fibre number is big, will make Fabric Style, feel, wearability and DIMENSIONAL STABILITY all be subjected to very big influence.Another problem is that static is big, the dyeing difficulty.At present both at home and abroad all at its modification technology of research, make it reach that fiber number is low, antistatic, easy dyeing.But all there is not any good way.What have in the world takes chemical method, promptly reduces intermolecular friction and reduces molecular weight.But the section Material Cost after the modification is too high, and quality is also unstable.
The objective of the invention is to propose a kind of method of making superthin antistatic color polypropylene fiber.Specifically be in indirect spinning technology, to add antistatic dyeing master batch and utilize improved filament spinning component, to produce desirable colour superfine dawn antistatic fibre.
Technical scheme of the present invention is, is mixed with antistatic dyeing master batch by carbon black or metal derivative and poly-ethanedioic acid phosphate.Because carbon black or metal derivative all are the materials that conduct electricity very well.Carbon black or metal derivative both used as antistatic material, used as pigment again.As spin black fiber and then add carbon black, as spin redness, then use as pigment and antistatic additive with red metal derivative.What adopt is indirect spinning technology, in the production antistatic dyeing master batch is quantitatively joined in the polypropylene chip material, makes colored polypropylene superthin antistatic fiber by improved filament spinning component on the spinning machine again.Its concrete scheme is:
One, the preparation of antistatic dyeing master batch
(1) prescription (weight ratio)
Carbon black or metal derivative 1
Poly-ethanedioic acid phosphate 1
(2) method for making
With above the two mix in proportion, through fully stirring it is mixed, send comminutor or extruder hopper then to and after fusion, make shot-like particle or extrude the antistatic Masterbatch that strip is cut into section again, pack standby.
(3) joining day and addition
Joining day: in spinning produced, raw material and Masterbatch entered the spinning machine hopper simultaneously
Addition: Masterbatch is 0.8～1.2% of a pp material
Two, improve filament spinning component
Filament spinning component on the existing spinning machine is to be made of package shell, spinneret, spinnerets, filtering material, bridge plate and pressing section, is cylindrical shape.The so-called filament spinning component that improves is to be improved to big molten chamber by the little molten chamber of the spinneret in the former common filament spinning component.Increase more than 2～3 times on original basis at the wire vent hole cross-sectional area on the spinnerets on the former assembly.Just increase spinning first melt chamber and enlarge wire vent hole cross-sectional area.Polypropylene fibre is difficult spinning fine denier filament why, mainly is due to its self structure, does not have polar molecule and polar functional group in polyacrylic molecular structure, and the big molecule of polypropylene fibre does not have attracting each other of molecular separating force, but by big intermolecular mutual winding.When so molecular weight will be quite big, just has the certain physical mechanical performance, and molecular weight is big, its strand length is bigger tens times than polyester and polyamide strand length in addition, thus mobile extreme difference, so just must the high temperature spinning, to add large fluidity, but the high temperature spinning can cause molecular weight degradation again, and influences its mechanical and physical performance, and the broken phenomenon of melt is serious.In spinning process, material is entered by the porch of screw rod, and in the screw rod of heating, material is extruded, fusion, enters spinning manifold by conduit, enters filament spinning component at last, is extruded by spinning head then, and cooling forming makes fiber.What determine spinning effect in this course is exactly the state of material in filament spinning component, and the state homogeneous satisfies technological requirement, and spinning effect is all right.Because common spinning first melt chamber is little, so in order to catch up with spinning speed, the material melt will reach the state of technological requirement when carrying, just melt will reach when carrying or near spinning temperature, cause the melt heated time long, the molecular heat signs of degradation is serious, and its degradation rate reaches about 30%, so just can not get good fiber.Big molten chamber spinneret concentrates on the technological requirement temperature control point on the filament spinning component exactly, makes material be in low-temperature condition in the past at filament spinning component as far as possible, and the control operation temperature to reduce thermal degradation, keeps it to have good physical property.Increase aperture, spinnerets wire vent hole, just increased the wire vent hole area.The material melt is when flowing through spinnerets at this moment, and the compression ratio of melt reduces, and the streamline shrinkage factor reduces, and relative shear stress reduces, and corresponding elastic energy is stored and also reduced.On the contrary, little as the wire vent aperture, the compression ratio of melt increases, and turbulization is rolled the big molecule of melt and advanced, and causes the macromolecular degree of order to descend when fiberizing, and powerful the reduction is difficult to obtain acceptable fiber.Increasing the wire vent hole area in addition, also is to set up a melt drawing zone in spinning moulding, and the big molecule of polypropylene fibre degree of order in drawing zone is increased, and makes physical property optimization.After the strand moulding, make strand become thinner during by drawing zone.Improve filament spinning component, come down to make polypropylene fibre in spinning process, can keep the favorable mechanical physical property, and in the end still can keep its various performances after with the fiber drawing-down by drawing zone.Thereby make coloured, ultra-fine, the antistatic polypropylene fiber of function admirable.
The inventive method is simple, easy operating, and production cost is significantly less than the like product that additive method is produced.The product quality height, function admirable.For present production equipment of China and the lower present situation of technical merit, the present invention is a kind of economical and effective method that very meets the high-grade superthin antistatic color polypropylene fiber of production of our actual conditions.
The present invention does not have accompanying drawing
