Detailed description of the invention In the present invention, a fabric is made from hollow filaments containing a liquid; Visible color-coded micromagnets or other rotatable magnets are placed in the liquid. There is a material that is sensitive to air and rotates freely. The color of this new fabric is optional. Can be changed. For example, if the filament is placed on a loom, In textiles, the filament strands are used for both warp and weft yarns. good.

Woven fabrics are also made by using the filament strands as warp yarns on looms and manufactured by using transparent synthetic resin threads as weft threads or vice versa. Sometimes it is built.

When the filament strands of the present invention are used in other types of textiles, Filament strands located adjacent to each other in parallel relationship adhere to each other's neighbors It is possible to produce fabrics having longitudinal strands running simultaneously. If you want If possible, place one length of this fabric across the other and glue them together. This allows the production of extremely strong laminated materials.

This fabric can also be adhered to a lining or support, and if the lining is opaque. If it is clear, observation is made from the filament side. If the lining is transparent, 1! Observations may be made from that side. To improve optical properties, fabrics can be You can also apply dark paint on the other side.

One convenient way to make adjacent filament woven materials is to create woven materials around a rotating drum. The filament layer is wound spirally around the filament, and then the filament core is The tiles can be glued together in one of several ways. One of the cool ways is to apply clear glue across the filament coil, and the glue (drying force) After curing, the resulting fabric is cut along the drum and then opened. Remove. The surface of the drum must, of course, be made of a material to which the adhesive will not stick. or have a coating of such material. stomach. For example, when release paper is first used to coat the drum, it is used for this purpose. Very useful.

Another useful way to bond filaments together is to use filament strands. By wrapping it in a spiral around the drum when it comes out of the press die, The filaments are then heated to a temperature high enough to cause adjacent helices to fuse. still holds the degree. Under these conditions, the filament becomes self-adhesive and its The resulting fabric is free of any adhesive for bonding between the filament strands. Removed from drum without need.

If backing is desired, the fabric removed from the drum may be lined with paper, cloth, or plastic. It can be glued to a material such as wood or metal. or alternatively, paper or cloth to the filament coil while it is still on the drum. Once bonded, the fabric and lining may be removed from the drum as a unit.

The filament of the present invention can be used to form transparent hollow fibrous strands at the same time. It is filled with some transparent liquid and holds a magnetically sensitive material that allows the liquid to rotate. Manufactured by the fact that it has From an extruder of the type shown in FIG. A molten transparent material is drawn onto a take-up reel while a liquid is passed through a tubular mandrel. The hollow filament is filled as it emerges from the die.

The filament material has good drawdown potential and can be wound on the take-up reel. Selected to provide thin, fibrous, hollow, liquid-filled filaments be done.

The following non-limiting examples further illustrate the invention.

1st birthday 3/4″ 25:1 extrusion hole, ionomer resin (Sark 7 Surlin #1555, DuPont) first heating zone 275'F1 second heating zone 4 7!5'F, and the die heater was used at 350°F. micro magnet The containing liquid is forced through a tubular mandrel from a sealed container under air pressure of approximately 2 psi. It was done. The liquid used was polybutene (Indopol L-1 4, 7 Moco Amoco) 1', and a small Bentone. #38 (NL Industries N, 1.rntiustrte s, Inc.) and dispersed under severe shear force to obtain thixotropic properties. was given. Next, in 150 grams of that liquid, 30 grams of platelet-shaped, wide Color-coded micromagnets having dimensions of approximately 5 mils are dispersed to reduce the mixture. The mixture was stirred under pressure to remove bubbles. Micro magnets mainly contain color fillers and barium ferrite. Light, and made from PVC binder. extruder screw is 16rpII1. to give time for cooling while rotating at a speed of A take-up reel several feet apart holds approximately 400 ft of 15 mil outside diameter filament. The vehicle was picked up at a speed of

(Optionally, downstream equipment may be used, but here we use various follow-on devices for cooling. Conventional equipment will be incorporated. ) The filament now on the take-up reel is unusable. This filament is prepared for use on the mR using known weaving techniques. Fabrics with several different weaves, each with the desired pattern, can be easily selected by can do.

Example 2 In another experiment, the finished filament was pre-washed with release paper as before. The material was re-rolled onto a large drum coated with silica and arranged in a single layer in a spiral pattern.

The filament coil is then combined with vinyl acetate and long chain acrylate (Gelva Ge1). va TS-100, Monsanto Hon5anto) copolymer, and After the binder has dried and hardened, the resulting fabric is cut and bonded. It was removed from the ram.

Many other adhesive bonding agents can be used for this purpose, including but not limited to: Polyvinyl butyral (Butvar B) dissolved in acetone 79, Mont Santo Hon5afltO) and several different types of rubber cement It has been used before.

Example 3 A winding drum was used in this experiment, positioned approximately 18 inches from the extruder die. was placed. The extrusion resin used was an ionomer resin (Surlyn #1702, DE Pont). The first heating zone is at 200″F, the second heating zone is at 475°C, and The die heater was set at 325 below. The liquid used was white mineral oil HIo 6014゜Atlantic Litchfield AtlanticRi cMield) into which bentone #38 was predispersed under high shear force. It was 12 gram color-coded micro magnets with an average width dimension of approximately 6 mils The mixture was then dispersed in 150 grams of the liquid. Micro magnets are mainly colored Made from pigment, barium ferrite, and acrylic-nitrocellulose binder It was a good thing. While rotating the extruder screw at 20 rpl, Adjust the speed of the rotating drum to take up the filament with an outer diameter of about 20 mils, and While the lamen still retains enough heat, go to the drum and touch each helix next to it. I glued it together. When a single layer coil is wound on a drum, the resulting fabric The filaments were already bonded to each other, and the bonded connection was removed. No adhesive was required.

Example 4 The extrusion resin used in this example was ethylene-vinyl acetate copolymer (Wurth 5t). 636111tl’athene 636゜nee varnish industrial ke Mical Company tl, s, Industrial Ch9mical C o, ), and the liquid is 415 propylene glycol and 115 glycerin by weight. It was a mixture. Separately, 10 grams of Benton L was mixed with 400 grams of water. Prepare a mixture and add 10 grams of this mixture to propylene glycol-glycerin 14 W in 0 grams! I added it as a compliment. Next, in this liquid, the micromers described in Example 3 were added. 10 grams of gunnets were dispersed. Cut the first heating zone and cut the second heating zone to 350″F , and with the Gui heater at 300'F, the outside diameter is about 14 mils and the inside diameter is about 13 mils. filament was taken up on the take-up reel. Screw speed for this size is 22 rpm 1. : The pressure to force the liquid through the mandrel is set at 5psi. there were.

In the next experiment, the take-up drum was placed approximately 24 inches from the extrusion die. so that each helix wound on the drum sticks when it comes in contact with the previous helix. did.

The fabric thus obtained was then cut open and removed from the drum.

The rotating drum used for this purpose was a rotating drum around which the incoming filament It is designed to also proceed laterally to form successive layers of helices in contact with the was.

A wide variety of cutting tools are used to cut the coil layer wound on the drum, such as guillotine blades, Easily accomplished by either a simple cutting blade, hot knife cutter, etc. That will be understood. The heated cutting blade cuts through the material and cuts it into a drum. This has the advantage of sealing the end of the filament at the same time as removing the filament.

If desired, the ends of the filament strands may be sealed with a suitable adhesive. Alternatively, it may be closed by melt sealing. However, in everyday use, even if for example, the viscosity and/or thixotropy of the liquid, the fineness of the filament inner diameter, Depending on the capillary action between the filament and the liquid, the end of the filament must It does not necessarily have to be sealed.

The size of the filament taken up by the take-up device depends on the speed of the take-up reel and the extrudate. heat, the rate of extrudate exiting the die, the ratio of liquid to extrudate, or and other factors, such as the flow properties of the extrudate material itself, etc. You can choose according to the following.

The desired filament size, among other considerations, The size of the magnetically oriented object held within will be taken into account.

For example, a micromagnet with a width dimension of 1 mil is housed in a filament with an inner diameter of approximately 2 mils. can. Therefore, a filament with an outside diameter of 3 mils and an inside diameter of 2 mils will produce a 1 mil size magnet. It works well with ki-responsive objects. The theory is that the smaller the object, the smaller the filler. can be accommodated in the ment. The filament has an outer diameter of approximately 10 mils and an inner diameter of 9 mils. It turned out to be quite satisfactory. Preferably 30 mils or thicker. However, if it can be viewed from a relatively long distance, e.g. In cases such as demonstrations, it is appropriate for visual acuity.

The curvature of the filament creates a lens-like effect on the internal micromagnet. This feature was found to make the color of the magnet brighter and stronger. is also taken into account when sizing filament for use in a particular fabric. You can also be

In cross section, the filament may be circular, but may also have other shapes, e.g. It may be a shape, quadrilateral, triangle, polygon, etc. The cross-sectional shape depends on the die design. It is determined that

Pressure used to regulate the flow of liquids containing magnetically sensitive rotating objects It is regulated depending on the desired discharge speed of the material and is controlled by various means, e.g. pneumatic pressure, metering pump. It can be applied either by pressure, gravity, etc.

Various liquid to micromagnet ratios were used. it is based on weight Ratios of about 3=1 range from low to about 10:1, with ratios of 5-6:1 commonly used. It was done. ('fIffi was used merely for measurement convenience.) However, for a given The desired ratio under the given conditions may be outside this range, in which case this The ratio depends on the size and shape of the micromagnet, and the relative relationship between the micromagnet and the liquid. It will depend on factors such as the viscosity of the liquid.

Air bubbles may form when preparing the micromagnet and liquid mixture. , especially when vigorous agitation is used; unwanted air bubbles can be removed under reduced pressure. It can be removed by stirring.

Said die provides a filament containing a single vein of liquid. However, slot with two or more liquid outlet orifices arranged in a jet-shaped nozzle. The die is a press that simultaneously discharges several parallel veins or channels filled with fine liquid. It can be built inside the performance.

Thus, for example, from a die with two adjacent orifices, the extrudate It comes out with two fluid-filled veins inside.

Therefore, the fabric of the present invention is a material that has been used directly from the die and has inside it Contains a magnetically sensitive material that holds multiple fluid-filled veins and allows the fluids to rotate Includes what you are doing. This ribbon-like material can be used as is or for its intended use. Depending on the application, it may be combined with other similar materials or with filament strands. could be used to form a textile layer.

Any transparent material can be shaped so that it has liquid-filled veins As long as it can be used as an extrudate. Examples of these materials include, but are not limited to: , polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyvinyl chloride including polymers such as nylon and nylon. Ethylene-vinyl acetate copolymer ( Ultrasen UE656, Ni Nis Industrial Chemical Company -) and polyvinyl chloride (Zeon 8883, B-Fugu”/Do 1,1 ”/CH 3. F, Qoodrich) are two types of It is a material like.

As is well known in extrusion technology, temperature settings follow the melt properties of the polymer. It is done. For example, if the above polyvinyl chloride is used, the first heating zone is 250”F, the second heating zone is 375°F, and the die heater is 325°F. Met.

The extrudate is selected in part with consideration to the liquid selected. For example, certain liquids body has a tendency to mix with certain extrudates at the melting temperature of the latter and therefore This may damage the quality of the filament. For example, some mineral oils are However, some mineral oils may have a tendency to mix with Useful filaments have been made using certain polyolefins as extrudates. There is. Therefore, the selection of the combination is best reached by simple preliminary tests. It is good.

The liquid chosen to hold the magnetically sensitive material is hydrophobic, e.g. mineral oil, Can be vegetable or animal oils, or combinations thereof, or hydrophilic such as glycerin, polyethylene glycol, propylene glycol, It may be water or a mixture thereof. Some of those mentioned in the examples above The hydrophobic liquid used in the crab was clear roll old earol (Witco ) and white mineral oil 18 USP (Amoco). used Vegetable oils include sunflower oil, corn oil, peanut oil, and vegetable oil. It was garlic oil. Examples of animal oils included cod liver oil and cow foot oil. . Mixtures in the form of emulsions can also be used, but such factors as thickening and cost Further adjustments are required to take this into consideration. These liquids usually impart thixotropic properties It will be done. This property is fully explained in the above-mentioned patents.

Thixotropy includes bentone LT, xanthan gum, and propylene in hydrophilic liquids. Given by glycol alginate, or hydroxyethylcellulose However, both were first dispersed with water to form separate formulations. Thixotropy is Umed silica (caposil cab-o-sil) has both hydrophilic and hydrophobic properties. given to the liquid. The extrudates used require relatively high die temperatures If the It should be kept free. However, in sufficiently cold dies, and relatively low melting Water can be used in any proportion when dealing with extrudates that require temperature. Alternatively, it can be used alone.

The adhesive used to join the filament strands must be transparent No. They are also of the type that cures by evaporation of the solvent or by catalytic action. It is fine if it is. Hot melt materials that harden upon cooling can also be used. fabric The adhesive for bonding to the lining is selected to be a permanent bond or , for applications such as wall coverings, because the fabric can be easily applied and removed. It may be desirable to apply a pressure sensitive adhesive to the fabric.

As will be clearly understood, the present invention applies to a wide variety of filament i-sequences and It includes textiles having a textile structure obtained by A large number of filament strands The above for composites that are interwoven or arranged parallel to each other. The description is for illustrative purposes only. The invention further provides, for example, a single long filament. Take a thin strand and loop it back and forth, or create a spiral. to give the result a multi-strand look, then bind or join it An example can also be given.

The invention is not limited to color-coded micromagnets.

Any other oriented object that can be selectively oriented to produce a visible display. You may use what you can.

Thus, for example, °U.S. Pat. MicroMag with color-coded magnetically sensitive particles as described in No. 21.315 When used in place of a net, the magnetic particles tg will exhibit a color change when rotated by a magnetic field. Alright is published by Youngquist (YOIJn(lqtlist) et al., to cite other examples). No. 3,013,206 Magnetic crystals may be used in textiles, as well as Ballinger's As described in U.S. Patent No. 3゜683.382 issued to Highly reflective flakes such as those that are not driven by magnetic or electrostatic fields Those that can be used can be used for textiles.

Although the apparatus described here was of an experimental scale, it is obvious to those skilled in the art that The expansion of scale for human production requires the use of larger equipment and well-known plant setups. This can be easily achieved by applying the principle of measurement.

Therefore, in Example 1, the extruder was running at about 15 rpm; It had about 5 times the power. Therefore, the extruder has a speed of approximately 2000 feet/min. It was possible to produce 15 mil filament at a speed. Winding as described in Example 1 The reel had a diameter of 3 inches and a length of 6 inches. 8 inch for winding drum It included a diameter of 12 inches and a length of 12 inches. The other drum is 16 inches diameter and a length of 16 inches. Larger diameter and length drums In fact, it can be easily put into practice in readily available conventional equipment.

As mentioned above, the present invention provides many benefits over previous work in this field.

Among these is ease of manufacture.

Encapsulation of liquids containing magnetically sensitive materials no longer requires costly solvent evaporation or Because it does not rely on curing or time-consuming curing, this product is now far more affordable. Easy and economical to manufacture. First, for liquids containing magnetically sensitive materials, Eliminates the need to make a pusel or spherical shell and then place it in continuous grout wood; And with it the need for large amounts of binder materials, process costs such as mixing, drying, etc. time and potential environmental pollution resulting from evaporation of the solvent are also eliminated. Furthermore, the present invention products are flexible, relatively light weight, and easily rolled and folded for storage. Therefore, it can be applied to a wide range of applications. Moreover, this product has a structure that greatly simplified and improved structural strength as well as improved optical properties Therefore, the incident light that enters the fabric and is reflected from the internal material has this Minimum resistance is encountered in materials of new and simple construction.
