Fig. 3 is along a distribution plate of 3-3 cross section intercepting among Fig. 4 and the partial sectional view of a spinnerets;
Fig. 4 is the bottom view of distribution plate shown in Figure 3.
The electrostatic dissipation fiber is that the crowd knows in this professional domain known, and used in weaving industry many years.A kind of successful especially fiber is a United States Patent (USP) 3,803, the sort of fiber of being introduced in No. 453.This fiber is by respectively as two kinds of thermoplastic component sheath-core bicomponent fibres that co-extruded is made under molten condition of crust and core.Its crust insulate.Its core polymer has electric conductivity by the fusion conductive black.This crust is used for increasing the intensity of fiber, the core of parcel black, and the protection core is to prevent contingent cut-out and layering when core exposes at fiber surface.Some current final use requires fiber to have bigger anti-electrostatic effect and considers less to its color.Especially, have stronger hope, wish to the core color see more clear a kind of differentiating method with the clothes that is not protected as the clothes that uses core to be protected and core.The applicant has found that this respect can pass through United States Patent (USP) 3,803, and No. 453 sheath core fiber carries out sex change to be realized.This sex change mainly comprise adopt with this patent in used core have the core of same composition but the plane of structure shape of core adopts three to sexfoil, its sex change ratio is at least 2, and each leaf L/D ratio is 1 to 20.Fig. 1 illustrates a kind of like this cross section shape.
Fig. 1 is the cross sectional representation of a sheath core fiber, and trilobal core that is wrapped up by a crust shown in the figure is as what arrive seen in the amplification picture of microphoto.The characteristic of core and crust will be described in more detail below.The sex change ratio determine what this professional skill field people knew, but for simplicity, can be by determining referring to Fig. 1.This sex change ratio is meant the ratio of trilobal core minimum circumscribed circle radius and each leaf maximum inscribed circle radius of trilobal core.In Fig. 1, be to represent with A/B.
Also can draw for the definite of each leaf L/D ratio referring to Fig. 1.Article one, straight line is that minimum point with two adjacent valleys of leaf both sides links up and obtains, and another straight line L is the line of the center of article one straight line to this leaf solstics.The leaf Breadth Maximum that the D value representation records on the direction perpendicular to L.Fig. 2 is the cross-sectional view with circular fiber of quatrefoil core.
Continuous yarn spinning process of the present invention is to consider that suitably the different performance of two kinds of components finishes by two polymer sheath core fiber spinning equipments of routine.This long filament is to be easy to adopt known spining technology with for example at United States Patent (USP) 2,989, and that base polymer of being introduced in No. 798 is made.The technology of this spinning with polyamide material is at United States Patent (USP) 2,989, done further description in No. 798.Succeeded in developing the preparation method after a kind of improve, made to have three, four, five or the sheath-core bicomponent fibre of sexfoil core when extruding, can keep the profile boundary preferably.To be explained below.
Be used for preparation method after the improvement in the core-skin type bi-component silk thread spinning of following example 1 and example 2 and be improvement to the core-skin type bi-component fusion spinning preparation method of routine.In the preparation method of routine, core feeding polymer flow and crust feeding polymer flow all are advanced in the spinneret component that comprises filter screen and screen cloth, and then deliver to a polymer flow and be assigned to plate on a plurality of apertures fusion, these holes are used to the core that is shaped, and wrap up this core with crust.To help to understand this improved technology referring to Fig. 3 and Fig. 4.The core polymer is delivered to passage 2 and above the import of leading to the pore 3 on the spinnerets 5, discharge.Sheath polymer enters in the space that is kept by unshowned pad between plate 5 and the plate 8 through the passage 7 of distribution plate 8.Sheath polymer near the inlet port of spinnerets pore 3 from around send to the core polymer flow, two kinds of polymer flows flow through pore 3 with skin, core relation, finally from the spinneret nozzle (not shown) ejection of the outlet of pore 3.This improved preparation method can keep the wide boundary of core lobed wheel preferably.This be by the control fusion the sheath component polymer flow along the periphery of the inlet port of spinnerets pore to the flowing of core polymer flow so that make flow into each leaf between sheath polymer stream in the zone realize more than the method that flows into the sheath polymer stream in each leaf zone.This can realize by only strengthening those each section passages that import in each zone between leaf of the passage that is used for making sheath polymer enter pore.Therefore, as shown in Figure 3 and Figure 4, on distribution plate 8, erode away some recessed portions 10 so that the sheath polymer stream of increase can be flowed in each zone of leaf.
The long filament crust can be made up of any squeezable, synthetic, thermoplasticity, fibre-forming polymer or copolymer.These polymer comprise TPO, for example polyethylene and polypropylene, polyacrylic acid, polyamide and the polyester that becomes fine molecular weight.The sheath polymer of particularly suitable is a polyhexamethylene adipic acid amine, poly-own (interior) acid amide, and polyethylene terephthalate.
The stretch capability of long filament of the present invention and other physical property depend primarily on sheath polymer.For the high long filament of intensity, skin material can be with having high molecular weight polymers and the higher polymer of those draw ratios.Though the long filament that does not stretch of the present invention can provide enough intensity for some purposes, the long filament of drawn is better.In some application scenario, for example long filament of the present invention need with other long filament stand to resemble hot fluid sprays that bulking is handled or other bulk processing the high-temperature process occasion, importantly sheath polymer will have sufficiently high fusing point to avoid occurring soft or melting phenomenon under this condition.
The long filament core of antistatic fibre is made up of the conductive black of disperse in a kind of polymer thermoplastic matrix material.United States Patent (USP) 3,803 is mainly considered in the selection of this core material, the electric conductivity and the processing characteristics of No. 453 detailed descriptions.Carbon black concentration in the core can be 15% to 50% selection.Have been found that 20% to 35% content can obtain the high conductivity of preferable level when processing characteristics keeps comparing reasonable level.
The core polymer also can be selected from same group of used material of crust or can select non-fibre-forming material, because it is being protected by crust.For non-antistatic fibre, that yes is non-conductive for the core of bicomponent fiber.
The size of the core cross-sectional area in the bicomponent filament yarn only need be enough to reach desired antistatic property, and can hang down by volume to 0.3%, preferably greater than 0.5% less than 35%.Its lower limit depends primarily on the suitable successional ability of making the crust/core long filament with enough homogeneous qualities simultaneously of core of maintenance under the lower condition of core volume.
Can adopt conventional long filament drawing process, but must careful operation the wedge angle of fracture or damage occur with the core of avoiding occurring causing antistatic fibre.In general, preferably adopt hot-stretch, just in drawing process, adopt some auxiliary long filament heat treated.Do like this and help to make core material further to soften and help the stretching of long filament.These antistatic long filaments can extend silk with the not position of common synthetic fiber and the common long filament that stretches is pooled capital.
For general application scenario, the DENIER of every rhizoid of long filament of the present invention (dpf) is preferably less than 25dpf less than 50.
Long filament of the present invention is aspect all types of textiles final uses, and comprising knitting, synthetic tuft is weaved and nonwoven textiles, and goodish electrostatic protection can both be provided.These long filaments can contain conventional additive and stabilizing agent, for example dyestuff and age resister.The weaving processing that this long filament can stand kind type is comprising curling distortion, washing and bleaching etc.This long filament can mix and can be used as staple fibre or long filament with short fibre yarn or filament yarn.
Above-mentioned long filament can or mix with other long filament or staple fibre in the fabric knitting process in any suitable operation (for example spinning, stretching, distortion, plying, rewinding, spinning) of spinning.In these operation process, should note reducing the undesirable fracture of wire phenomenon of antistatic long filament
Bi-component polymeric stream is in case spray the spinnerets aperture and promptly cool off and begin and solidify.Generally do not wish conductive fiber is applied too big spin-drawing power, because make to reduce the quality of antistatic fibre like this.Other bicomponent fiber is not subjected to the restriction of this point.
