Description

[Detailed description of the invention]

The present invention relates to staple fiber blends and carpets containing novel synthetic filaments with antistatic properties consisting of a continuous non-conductive sheath of synthetic polymer surrounding a conductive polymer core containing carbon black. The use of thin, insulated, conductive wire with non-conductive synthetic fibers to produce carpets with low static charge is described in U.S. Pat. No. 3,639,807. In kits that include conductive wire, the wire is bent and twisted and therefore less effective. The use of conductive carbon black dispersed throughout the fibers for use in antistatic textile applications is disclosed in U.S. Pat. No. 2,845.
, No. 962 and No. 3.706.195. However, these fibers have poor mechanical and physical properties, such as brittleness and low tenacity, and therefore do not have a sufficiently long life during normal consumer handling and use. This is reflected in U.S. Pat. No. 3,582, which describes the application of a conductive coating containing carbon black on synthetic filaments for antistatic purposes.

It has been found that for some mallet applications, the disadvantage is that they do not have the ability to satisfactorily reduce the stripping resistance of AM filaments and AM fabrics made therefrom. Also, both of the antistatic filaments described in the above two US patents are yl!

Another disadvantage is that the anti-static property is lost. According to the invention, thermoplasticity is achieved by forming a continuous mass of thermoplastic fibers surrounding a specialized core consisting of a composite body and conductive carbon black dispersed therein. consisting of a non-conductive sheath, said sheath occupying at least 50% of the cross-sectional area of the filament (i.e. occupying at least 50 volumes), and when a DC voltage of 2 KV is applied to the core of said filament.

ation) It has a sheath with molecular orientation as a result of the sheathing. Commercially conductive core compositions, ie compositions containing more than 20% carbon black, are preferably used in filaments having a sheath content of at least 80%. The present invention provides an antistatic filament that can be used in light colored rectangular products. For such an end purpose (2), the cup pods account for at least 90% of the F filaments, and the pods are W color? Portrait 7
Partially hide the color of 6 (5), and the light reflectance of the filament should be greater than 20. The filament contains 2 to 7 pieces of titanium oxide in the sheath. Co-bulk can be dyed according to the color and becomes bulky under the conditions of sleep and misery (co-bulk
), and the toughness of the filament (7) makes it possible to use it for the final purpose, since the mold cost is less. Although the filament of the present invention consists of a non-conductive sheath that
In order to prevent the accumulation of static electricity, other birch materials consisting mainly of fabrics, yarns or other synthetic materials with antistatic properties, fibers or filaments may be used. It can be used as a raw material as a component of oboroka, regardless of relative humidity. In fact, the present invention also provides non-free synthetic filaments and 20 spout IA, less than 1111% of the present invention's fission toy Kuntai! It shall also include anti-caesarism yarn 7 (+7) and stable fi/ζ- containing ILIA, which is +7 from 1. Conveniently, the filaments or stesol-no-inosore mixtures of the present invention can be in the form of a mixture of stable fibers, for example, or can also be in the form of continuous filament yarns. Of the present filament in such a mixture, the 110 range gives good antistatic properties even when it is present in proportions less than 2%, but this mixture is above +4

These fibers have an excellent balance between conductivity and antistatic properties, and do not have an undesirable color. The present invention also includes a non-conductive sheath component made of a synthetic thermoplastic polymer capable of forming fibers, and a thermoplastic polymer and a conductive material dispersed therein (15 to 50% by weight). Co-spun with a conductive core component consisting of carbonaceous black, the core component is surrounded by a sheath component and at least 5 of the filament's vf1tIli bonds are surrounded by the core component.
This invention relates to a method for producing a fluorophore-proofing filament which is a special imitation of the older brother L2 Merkotoge in the form of a sheath/core filament that occupies 0%. Hereinafter, the present invention will be congratulated with reference to Fig. 1I11. In the filament shown in Figure 1 (5), the core material (1) is a polymeric matrix surrounded by a sheath (2) which is received from the non-conducting base.

[7. Either insert a coffin into the sheath and bring it into contact with the core, or use an electrode in contact with the surface and create enough tube straightness to cause the sheath to induce iron fracture. Once it comes into contact with the core under pressure, it exhibits high electrical conductivity. In the latter case, i.e. when using a surface contact TVC system, increasing the applied direct pressure to hundreds of volts, especially several thousand volts, causes a sudden and significant increase in current as described in the test method section below. A point occurs where the flow begins to increase. Once the 4 ftL property is met in this way, the captive flow will continue to flow even if the pressure is lowered to a low level unless the contact between the filament and the battery of the 611j fixing device is changed. The low resistance characteristic of this filament, indicated by 6, indicates that the damage is continuous (7) throughout the defined filament's erosion. The break in the continuity of the core at the jinma is indicated by the much larger relative resistance, which is close to the resistance of the sheath, of the filament of the present invention, even though the resistance of the filament of the present invention is sometimes IJJ. It has been found that the antistatic properties are not significantly impaired. !!It is preferable that this is the case even if the filament is a continuous filament.The filament has a sufficient length, 6 is continuous, and together with the curved antistatic filament, an antistatic network with an effect of 1rJ is created.

The polymer in the sheath that has no teeth in q is the condensation of sheapine and dicarboxylic acid @J theriamide and the condensation of aino Iya d? Condensed polyesters, particularly terephthalic or isophthalic acid, and lower glycols such as ethylene glycol, tetramethylene glycol, and hexyl-p-xylene diol; and poly(acrylonitrile). Such polymers can be used, for example, in co-colonization to introduce topical or acidic staining sites [7
, dyed or dyeable combinations, dyed or dyeable combinations, or reciprocal dyes can be modified by methods known in the art to impair their dye receptivity. The strength and other physical properties of the filaments of the present invention depend primarily on the polymer of the sheath. The obtained chassis body is used as a sheath.

It must be thick enough to provide heat and abrasion resistance and, if it is heavy, that the core is visible or crumbs. The thickness of the sheath is desirably at least 8 microns per die, and a thicker sheath may be used depending on the denier of the filament that can be used for one cycle. Textiles of Kyuzune
The thickness of the pod suitable for denier ranges from 8 to 22 microns. In some applications, for example, a high-volume fluid jet bulk commercialization matahito [Texture 1 processing operation, a paulownia table that performs a high-volume processing operation on the filament E7, may require a small amount of work under these conditions. Does the pod have a high enough melting point to prevent it from softening or melting? Must have. For such applications, small polymers of high melting point pods such as poly(hexamethyleneadipazurin) are preferred over rtrv<g-caproamide. The filament 6 is comprised of a thermoplastic polymeric matrix material and a fraction of the conductive carbon black therein. The core material is selected from four types, with electrical conductivity and workability as the primary considerations. Carsen black tma1 in the core

It's even brighter that it's lower than that. Even more highly conductive Kasen blacks made by known specific methods are effective in minimizing the required drag. When Carsen Black is applied to streetcars, the plastic composition tends to become stronger or harder.
The strength of the 6-matrix material is preferred over the harder, lower melting point versions. ,V:! It is preferable that the melting point of the chassis body is lower than that of the chassis body of the sheath. It becomes easy to cut the core and break the distribution of Karsen black particles.At the same time, the core and the final filament can be easily cut.

For example, oil and wax and plain 1 can be used to facilitate processing. Also, copolymers such as 4? (ethylene/vinyl acetate) copolymers can also be used. Car-in black can be dispersed in the core assembly by a known mixing method. During coalescence of the core, the feed must be sufficient to uniformly fractionate the carin black and allow extrusion without over-mixing and therefore without lowering the f+. In order to achieve satisfactory spinning, it is necessary to remove volatile materials from the composite to which the carbon black is added before melt spinning. Or after that, it becomes sticky.If such a combination is air-dried, for example, at 68°C for 16 hours, young fruit may be produced. Standard precautions are taken to prevent this, such as using the traditional method of passing an inviscid gas through the assembly line to remove oxygen. ) is sufficient to give it the desired resistance characteristics, 0.5 volume ffi
It can be as large as %. The lower limit is primarily governed by the steering force capable of producing a sheath filament of sufficiently uniform quality while at the same time maintaining adequate core continuity when the core volume is low. The filament of the present invention can be spun using a conventional two-way polymer abbreviation/core spinning apparatus, taking into consideration the differences in the properties of the two-way polymer components. These can be made using polymers by known spinning methods, for example, US 1N No. 986.482.

You can use the normal sail-off method of filament 1, but it will cut or damage the 1, 6, 4! I have to be careful to be able to do it. A preferred method is to heat the filament in one heating step, i.e. in heating the filament. This creates more intercostals which further softens the b-material and promotes filament deformation. These banded fabrics and anti-threshold filaments can be combined with ordinary synthetic filaments (p7y) to perform simultaneous IA. This filament can easily be made to have a strength of at least 1 bf/denier;
