Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric flocked fiber material and an electric flocked product, and more specifically, to a surface of a substrate such as a cloth, a fibrous material to be flocked by electric flocking, and the electric flocked fiber material. It is intended for electric flocking products manufactured using.

[0002]

2. Description of the Related Art Electric flocking is a process in which a voltage is applied to a base material such as cloth to which an adhesive is applied to generate an electrostatic attraction force, and a fiber material (also called pile or flock) that has been cut in advance is usually used. Called) is planted and fixed in the adhesive layer on the surface of the substrate. Depending on the material, shape, and structure of the fiber material, it is possible to exert unique functions and effects that are difficult to obtain with ordinary weaving and coating technologies on the appearance and surface texture of the flocked layer formed on the surface of the base material. . As fields of application of electric flocking technology, various clothing items, carpets, artificial turf, and other interior materials for construction or automobiles are known.

As a fiber material used for electric flocking, synthetic fibers such as nylon and rayon, synthetic fibers, and natural fibers such as wool and silk are commonly used in the past. In particular, nylon is often used in applications requiring durability such as interior materials for automobiles. Nylon is also excellent in giving it a soft surface texture. Depending on the required performance and application, polyester, polytrimethylene terephthalate, aromatic polyamide, etc. are also used.

[0004]

All of the above-mentioned electro-implantation products using the electro-implantation fiber material made of various synthetic fibers have a relatively smooth surface texture. Therefore, it is preferable for applications where surface slipperiness is required, but it is difficult to use for applications where surface slippage is disliked. In particular, when the surface of the electric flocked product gets wet with water, there is a problem that the surface becomes very slippery. Further, when the conventional electric flocked fiber material is flocked on the base material, it is difficult to flock the hair in a state of standing upright on the surface of the base material, and there are many variations in the directions and postures of the individual fiber materials. As a result, the surface texture and surface characteristics of the electric flocked fiber material may be impaired. When a load is applied to the surface, the transplanted fiber material may fall or bend, and even if the load is removed, the fiber material may remain fallen or bent.

When the electric flocked fibrous material is curled or twisted during electric flocking, when the electric flocking fiber material is made to fly to the surface of the base material by electrostatic attraction, variations occur in the flight path and direction, resulting in flocking. It becomes difficult to perform well, and even when the hair is transplanted, the direction and posture are likely to vary. An object of the present invention is to obtain, as the above-mentioned electric flocked product, one having a novel surface texture and surface characteristics that have never been seen. In particular, it is to obtain a product having excellent surface slip resistance. It is an object of the present invention to obtain such an electric flocked product and provide an electric flocked fiber material suitable for electric flocking.

[0006]

The electro-implanted fiber material according to the present invention is a fiber material that is implanted on the surface of a substrate by electro-implantation, and is composed of elastic fibers having rubber-like elasticity,
The electric leakage resistance value is 1 × 10 ^{7 to} 7 × 10 ¹⁰ Ω. [Elastic Fiber] A fiber material having rubber-like elasticity. As long as the elastic fiber is applicable to electric flocking, a material obtained by the same material or manufacturing method as that used for a normal knitted fabric or the like can be used.

<Material of Elastic Fiber> As the material of the elastic fiber, synthetic or natural resin material or rubber material capable of expressing rubber-like elasticity is used. Specifically, polyurethane elastic fiber, polyether / ester elastic fiber, and polyamide elastic fiber can be used. Fibers made of natural rubber, synthetic rubber, semi-synthetic rubber or thread-like materials, so-called rubber threads can also be used. A material composed mainly of a rubber material and a composite with another organic synthetic resin can also be used. For example, acrylonitrile
A butadiene-based copolymer, a styrene-butadiene-based copolymer, etc. can be used. It is also possible to use a material in which a plurality of types of rubber or polymer are mixed.

In particular, as a material suitable for the purpose of the present invention,
An example is polyurethane elastic fiber. The polyurethane elastic fiber has a high coefficient of friction on the surface and can improve the slip resistance.
The surface texture is also good. The linearity of monofilaments and fused multifilaments is also good. <Polyurethane elastic fiber> Polyurethane elastic fiber is a polyurethane solution prepared by dissolving a polyurethane polymer in a solvent. The polyurethane solution is spun by a dry spinning method, a melt spinning method, a wet spinning method, or the like and wound by a winding machine. Obtained by

In the spinning process, a fused multifilament can be obtained by immediately fusing and integrating a plurality of filaments simultaneously spun from the spinneret. If multiple filaments are solidified separately and then twisted together, a normal multifilament is obtained. If you get a single filament, it becomes a monofilament. Prior to winding, in order to make it easier to use in post-processing, a mineral-based or silicone-based additive containing additives such as anti-blocking agents and smoothing promoters, as well as an oil agent of these mixtures, is applied to the surface of the yarn. It can also be attached. Polyurethane polymers that are soluble in solvents are composed of two types of segments. That is, (a) a soft segment, which is a long-chain polyether or polyester segment, and (b) a hard segment, which is a relatively short-chain segment derived by the reaction of an isocyanate with a diamine or diol chain extender. Is.

As the soft segment, those derived from tetramethylene glycol, 3-methyl-1,5-pentanediol, tetrahydrofuran, 3-methyltetrahydrofuran, and copolymers thereof are preferable. Among them, polyether derived from tetramethylene glycol is particularly preferable. Other soft segments include (a) ethylene glycol, tetramethylene glycol, 2,2-dimethyl-1,3-propanediol and the like and (b) adipic acid, succinic acid and other dibasic acids. preferable. Copolymers such as polyetheresters formed from polyethers and polyesters or from polycarbonate diols such as poly- (pentane-1,5-carbonate) diol and poly- (hexane-1,6-carbonate) diol Is also preferable.

The hard segment is bis- (p-
Isocyanatophenyl) -methane (hereinafter abbreviated as MDI), tolylene diisocyanate (hereinafter abbreviated as TDI), bis- (4-isocyanatocyclohexyl) -methane (hereinafter abbreviated as PICM), hexamethylene Diisocyanate, 3,3,5-trimethyl-5
Organic diisocyanates such as methylenecyclohexyl diisocyanate are preferred. Among them, MDI is particularly preferable. As the chain extender, ethylenediamine, 1,3-
Diamines such as cyclohexanediamine and 1,4-cyclohexanediamine are suitable for forming polyurethaneurea.

It is also preferred to include a chain terminator in the reaction mixture to control the final molecular weight of the polyurethaneurea. As such a chain terminator, a monofunctional compound having active hydrogen such as diethylamine is preferable. As a chain extender, ethylene glycol, 1,3-propanediol, 4-butanediol, neopentyl glycol,
1,2-propylene glycol, 1,4-cyclohexanedimethanol, 1,4-cyclohexanediol,
Diols such as 1,4-bis (β-hydroxyethoxy) benzene, bis (β-hydroxyethyl) terephthalate and paraxylylenediol are preferred for forming the polyurethane. The diol is not limited to only one kind of diol, and may be composed of plural kinds of diols.

Compounds containing one hydroxyl group which reacts with isocyanate groups can be used in combination. Various methods such as a melt polymerization method and a solution polymerization method can be adopted as the method for obtaining the polyurethane polymer, but the method is not limited thereto. The polymerization formulation is also not particularly limited, and for example, a method of synthesizing a polyurethane polymer by simultaneously reacting a polyol, a diisocyanate, and a chain extender composed of a diol is preferable, and any method may be used. Good. The polyurethane polymer that can be used in the present invention includes benzotriazole-based UV absorbers, hindered amine-based weathering agents, hindered phenol-based antioxidants, various pigments such as titanium oxide and iron oxide, and barium sulfate. It is also preferable to contain a functional additive containing zinc oxide, cesium oxide, silver ion, or the like. By containing titanium oxide, iron oxide, etc., elastic fibers having a high surface friction coefficient can be obtained. If the original dyeing is performed with a coloring pigment, or if a fluorescent pigment, a warming pigment, zirconium carbide or the like having a special function is added, the intended function and effect of each additive can be exhibited. At the same time, it is preferable that the raw yarn is not disturbed by sieving and handling.

The polyurethane polymer is preferably dissolved in a solvent to obtain a polyurethane solution. As a solvent for preparing the polyurethane solution, N, N- dimethylacetamide (hereinafter abbreviated as DMA _C), dimethylformamide, it is preferred to use dimethyl sulfoxide. In particular, DMA _C is preferably used. From the viewpoint of spinnability and the like, the concentration of the polyurethane solution is preferably in the range of 30 to 40% by weight, more preferably 35 to 38% by weight, based on the total weight of the solution.

Polyurethane elastic fibers are less likely to be fused at the time of cutting and have a sharp cut surface. as a result,
At the time of flocking, anchoring property and uprightness to the adhesive layer are improved. Both the monofilament and the fused multifilament of the polyurethane elastic fiber are almost linear, and the "turbulent pile" caused by the degree of tension of the raw material fibers and the "coloring" and "twisting" of the filament hardly occur. It is difficult to cause the problem of flocking spots (crater effect) when flocking due to the mixture of fiber materials longer than the specified cutting length. In the case of a normal multifilament that is not a fused multifilament, the above-mentioned advantages are difficult to be sufficiently exerted because the filaments are entangled and twisted. However, a normal multifilament may be used in some cases depending on the application and required performance. <Properties of Elastic Fiber> As the elastic fiber, one having an elongation of 350 to 850% as a property for evaluating rubber elasticity can be used. Preferably, the elongation rate is 400 to 650%
Is. Modulus 200-350c showing tensile modulus
Those having N / km (weight at 100% elongation) can be used, and preferably have a modulus of 210 to 260 cN.
/ Km.

The electric leakage resistance value is 1 × 10 ^{7 to} 7 × 10
Elastic fibers of ¹⁰ Ω, preferably 2 × 10 ^{7 to} 5 × 10 ⁸ Ω are used. The smaller the electric leakage resistance value, the better the flight performance in the electric flocking process. Since many of ordinary elastic fiber materials have a large electric leakage resistance value, it is preferable to perform a pretreatment for lowering the electric leakage resistance value before the electric flocking step so that the electric leakage resistance value falls within the above numerical range. Elastic fibers, when used in the form of monofilaments or fused multifilaments, have excellent linearity, improving flight properties in the electric flocking process, anchoring to the adhesive layer, and uprightness after flocking. To do.

The length and thickness of the elastic fiber can be set according to the application and required performance of the flocked product. Normal,
0.1 to 20 mm in length, 6 to 2,500 dtex in thickness,
The aspect ratio can be set in the range of 0.4 to 50. Here, the length is represented by the maximum value of the transit length in the unloaded state, the thickness is represented by the maximum value of the transit diameter, and the aspect ratio is represented by the length / thickness. The elastic fiber can be used in the form of a cut fiber or a thread obtained by cutting a monofilament or a fused multifilament into predetermined lengths. As the thread made of elastic fiber, a curved thread that is curved or twisted can be used, but a straight thread having excellent linearity is preferable.

<Straight yarn> The dimensions of the elastic fiber to be a straight yarn are 0.5 to 20 mm in length and 44 to 2,500 in thickness.
It can be set in the range of dtex and the aspect ratio of 1 to 175. Preferably, the length is 0.3 to 15 mm and the thickness is 78 to
It has a dtex of 1,000 and an aspect ratio of 8 to 50. Further, from the viewpoint of linearity, the length is preferably 10 mm or less,
Further, the length is preferably 1 to 7 mm. If it is too long or too thick, hair drop resistance, dispersibility, etc. deteriorate, resulting in poor surface quality. By setting the length, thickness, and aspect ratio within appropriate ranges, slip resistance and cushioning properties can be improved.

The elastic fiber which becomes the straight yarn has a flexural modulus of 20.
The linearity is excellent in the range of up to 500 N / mm ² . The flexural modulus is preferably 30 to 200 N / mm ² . If the flexural modulus is too low, the product has a hair-falling property, resulting in an inclined electric flocked product. Even if the flexural modulus is too high, some fibers may not be upright but may be laid down while being planted, or the flocked surface of the electric flocking product may be rigid. <Elastic Fiber Powder> The elastic fiber can also be used in the form of powder by finely cutting or crushing filaments. By using the powdered electric flocked fiber material, thin and high-density flocked hair can be obtained, and the anti-slip effect is also improved.

The shape of the elastic fiber powder may be a columnar shape having the same cross-sectional shape as the filament and a short overall length, or a shape in which corners are cut off at both end surfaces of the columnar material, a sphere or the like. It may have a curved shape. The elastic fiber powder has a length of 0.1 to 1 mm and a thickness of 6 to 22.
The dtex and the aspect ratio can be set in the range of 0.4 to 50. Preferably, the length is 0.1 to 0.5 mm and the thickness is 6 to 1.
The range is 1 dtex and the aspect ratio is 4 to 35. If the elastic fiber powder has a spherical shape, the maximum radial direction
The direction orthogonal to that is evaluated by the thickness.

A fused multifilament can be used as a raw material for producing elastic fiber powder. The elastic fiber powder obtained from the coalesced multifilaments has a fineness corresponding to the filament diameter immediately after spinning, which is the fineness in the state of being split into individual filaments. By being divided, it is easily pulverized. When the monofilament and the cohesive filament having the same diameter are used, the cohesion filament may have a crushing efficiency of elastic fiber powder several times or more. <Coalescent Filament> Coalescent multifilament is a bundle of a plurality of filaments, like a normal multifilament, but the spun filaments are in a linear state without twisting or twisting. It is one that has been fused and integrated in parallel. In a normal multifilament, individual filaments are separated and are not fused and integrated.

The number of filaments of the fused multifilament may be any number of two or more, but usually two.
The range of ˜216 lines is adopted. It is preferably 3 to 110. The bonding may be arranged in parallel in one row or a plurality of rows, or may be stacked in multiple layers in the radial direction from the center. It is preferable that the filaments are integrated in the closest packed state, but a gap may be partially formed between the filaments. The overall cross-sectional shape of the fused multifilament is not limited to a circle or an ellipse, a polygon such as a triangle or a rectangle, an L-shaped figure, or an irregular shape.

The fused multifilament is preferably one in which all the filaments are securely fused over the entire length and there is no single yarn crack or non-bonded portion, but in part,
Single yarn cracks and non-bonding parts may be present. When performing the first-splitting / splitting process, it may be easier to perform the treatment if the cohesion is relatively weak. The coalesced multifilament is obtained by concentrating a plurality of simultaneously spun filaments (that is, multifilaments) in the spinning cylinder immediately before the oil supply roller, and fusing and integrating the individual filaments. The characteristics of the obtained fused filament can be adjusted by the production conditions such as the spinning temperature and the spinning speed. By twisting with an air entanglement nozzle, it is possible to achieve a close-packed state, partially fuse, and freely control.

The air pressure of the air confounding nozzle is 1.5 kg /
It is preferable to set it to be not less than cm ² (gauge pressure). A range of 3.0 to 4.0 kg / cm ² is preferable for complete fusion integration, and is used for partial fusion, that is, for forming single yarn cracks and for producing flat yarns having an L-shaped or I-shaped cross section. 1.6
The range of ˜2.9 kg / cm ² is preferable. When such a fused multifilament is compared with a normal multifilament, the fused multifilament has excellent flight properties in the electric flocking step and also has excellent uprightness at the time of flocking. This is because, in the case of ordinary multifilaments, it is necessary to apply sufficient twist to integrate the individual filaments into separate filaments, as a result of which linearity is likely to be impaired and flight performance due to electrostatic force is also poor. Prone. Since the fused multifilaments have the filaments fused and integrated with each other, they do not require twisting unlike ordinary multifilaments and can improve linearity and flight properties.

[Manufacture of Electric Flocked Fiber Material] Basically, in order to manufacture an electric flocked fiber material using elastic fibers as a material,
Ordinary manufacturing technology of electric flocked fiber material is applied. <Strand Converging Step> The spun elastic fibers can be bundled in a tow and handled. The tow is a bundle of filament fibers as they are without twisting. Elastic fibers can be bundled into tows composed of hundreds of thousands to millions of dtex by a tow producing device and method for ordinary fiber yarns. More specifically, an elastic fiber cake is set on several hundred creel with a warper with an elastic fiber feeding device roller.
Tow can be obtained by rolling up the frame. It is also possible to prepare several elastic fiber bundles by using an elastic fiber winding and stranding device similar to a cord yarn netting machine, and repeat this to store them in several bundles of storage cans.

<Cut Step> The elastic fiber is used after being cut into a length required for the electric fiber-implanted fiber material. As for the cutting device and processing conditions used for cutting, the same techniques as those for ordinary electric flocked fiber material can be applied. It is desirable that the cut end surface of the cut electric flocked fiber material be as sharp as possible. It is preferable that fusion does not occur at the time of cutting so that it is not rounded, bent, or twisted. The electric flocked fiber material with a sharp cutting edge surface is easily pierced into the adhesive layer during electric flocking, pierces deeply into the adhesive layer, strengthens adhesive fixing to the adhesive layer, and flocks upright. It has the advantage of being easily handled.

The fibrous material used for electric flocking is generally of uniform length, and evenly flocked, and the upright state is improved. If too long fiber material is mixed, problems such as flocked spots (crater effect) tend to occur. The elastic fibers bundled in the tow can be cut into a predetermined length by using a flock cutter device. By cutting the elastic fibers bundled in the tow with the tow as it is, it is possible to easily obtain an electro-implanted fiber material having a straight line and a uniform length and a good cut end surface. After the cutting step, a refining step, a dyeing step, an electro-planting step, a low temperature drying step, a sieving step and the like can be performed.

<Dyeing Step> The elastic fiber can be dyed if necessary. For the dyeing step, the same technique as that for a usual electric flocked fiber material can be applied. Either the dyeing method or the dyeing method can be applied. A post-dyeing method is preferred. <Electroplantation treatment> The conductivity of the elastic fiber can be improved, and the flight performance in the electroplantation step can be improved. Specifically, the elastic fiber is brought into contact with a treatment liquid of a silicon compound such as sodium silicate or potassium silicate or a water-soluble potassium compound such as potassium formate or potassium acetate.

Surfactants (anionic or nonionic antistatic agents), sodium silicate, colloidal silica and the like can be added to the treatment liquid. The pH of the treatment liquid
It is preferably used on the alkaline side having a pH of 10 to 12.
By setting the pH low, the electric leakage resistance value of the elastic fiber after the treatment becomes small. The electric leakage resistance value of the elastic fiber that has been subjected to such electro-planting treatment is set within the above-mentioned numerical range. The elastic fiber that has been subjected to the electro-planting treatment can be dried at a low temperature and then sieved.

<Sorting and sieving step> Sieving is a step of removing solidified elastic fibers, long fibers and disordered fibers.
The flocking can be made uniform, and the appearance quality of the electric flocking product can be improved. Basically, the usual manufacturing technology of electric flocked fiber material can be applied. For example, an octagonal rotary sieve is commonly used. The mesh of the sieve is switched depending on the length of the elastic fiber. Normal,
If the fiber length is 5 mm or more, 10 mesh or less can be used, and if it is more than 1 mm and up to 3 mm, 15 to 25 mesh and less than 1 mm can be 30 mesh. The rotation speed of the rotary sieve is typically 5 to 10 times / minute. As the rotation speed increases, the centrifugal force between the elastic fiber and the hopper acts and the drop of the elastic fiber decreases. Usually, about 6 times / minute is desirable.

It is preferable to apply the WET cutting method, cut into a certain length by using a pile cutting machine, and sieve the product several times to commercialize it. <Crushing Step> In order to obtain a powdery electric flocked fiber material, the spun elastic fiber or the elastic fiber obtained through the refining step, the electro-planting step, the dyeing step and the like may be crushed. Specifically, crushing technology for ordinary fiber materials can be applied. In the case of elastic fiber, a small amount is supplied by a disk or rotary stone mill method that compacts with a rough surface that does not have a cutting edge and has a roughening effect such as knurling on the surface, rather than a crushing device such as a ball mill. -It is preferable to grind at low rotation. More preferably, it is frozen and pulverized in a freezing chamber maintained at about -200 to -20 ° C.

[Electric Flocking Process] Basically, a general electric flocking technique is applied. The electric flocked fiber material of the present invention is electroflocked on the surface of the base material via the adhesive layer. The basic electric flocking process is to generate a high-voltage electrostatic field between opposing electrodes, place a base material coated with an adhesive on one electrode side, and apply an electric charge to the electric flocked fiber material to apply electric charges to the opposite side. Flies from the electrode toward the base material to implant hair. <Substrate> As the substrate, the same material as the substrate that can be used for ordinary electric flocking can be used.

Specifically, a knitted or woven fabric made of various synthetic fibers and natural fibers can be used. Flexible synthetic resin sheets and films, paper, natural and synthetic / artificial leather can also be used. Molded products such as synthetic resins, metals, wood materials, pottery, ceramics and inorganic materials can also be used. Examples of the knitted fabric include circular knitted fabric and tricot knitted fabric. A staple fabric made of spun yarn, a cotton jersey, a tricot fabric made of filament yarn, a plain knitted fabric, and a double jersey fabric, and a fleece pile, a velor-like napped knitted fabric, and a raised fabric are also preferable. As the woven fabric, those having various woven fabric structures can be used, and examples thereof include spun yarn, filament yarn, pseudo twisted yarn, and the like, as well as a mixed woven fabric of the same type of yarn or different types of yarn.

As the non-woven fabric, a non-woven fabric utilizing a usual non-woven fabric technology can be used. Dry type chemical bond, thermal bond, needle punch, spun bond / melt blow and spun lace, and dry type can be used. As the material, cotton, rayon, nylon, polyester, pyrene or the like can be applied, and the unit weight and the thickness can be appropriately used according to the application. As the base material, there are a material that does not substantially expand and contract, a material that has some elasticity, and a material that has excellent elasticity. Of these, materials that do not substantially expand and contract, for example,
A knitted woven fabric or a non-woven fabric having a slight stretchability (for example, an elongation rate of about 15% or less) as compared with wood, paper, metal and the like can improve the softness and flexibility of the electric flocked product. Wrinkles are less likely to occur even in a sheet material having a large area or a product having a curved surface. Restoration from hair fall of the flocked fiber material made of elastic fiber becomes faster. A repulsive force that elastically restores during deformation is generated, which also contributes to improvement of slip resistance. In the case of an electric flocked product using elastic fiber powder, it is dense and thin, the expansion and contraction of the base material and the elastic fiber powder are synchronized, adhesive peeling does not easily occur, and flexibility and slip resistance are improved.

<Stretchable Substrate> When a stretchable knitted fabric having excellent stretchability is used as the substrate, the characteristics of the electric flocked fiber material of the present invention can be exhibited well. Specifically, it is preferable that the elongation percentage in at least one direction is 20 to 40%. On some or all of the diameter weft threads that make up various knitted fabrics,
A stretchable knitted fabric can be obtained by using a tricot or covered elastic yarn made of polyurethane elastic yarn. When the stretchable knitted fabric is stretched in either direction or both directions, the knitted fabric stretches. When the external force is not applied, the knitted fabric has substantially no shrinkage force, and when the external force is applied, an appropriate shrinkage force or extension recovery force is generated.

When the stretchable knitted fabric is a knitted fabric in which stretchable fibers are interwoven or interwoven with other fibers, it has one-way stretchability in the warp direction or the weft direction depending on the structure of the weaving structure. Is obtained. The stretchable knitted fabric can more effectively exhibit the advantages of having the above-mentioned stretchability,
In particular, it is possible to exert synergistically without impairing the function of the elastic fiber. <Adhesive> Basically, it is selected from the adhesives used in the production of ordinary electric flocked products, depending on the combination of the base material and the fiber material and the required performance.

For example, a vinyl acetate resin, a reactive / self-crosslinking acrylic ester resin, an acrylic or urethane type adhesive, or a mixture thereof may be used. These adhesives are tricot,
It can be applied to knitted fabrics such as circular knits, woven fabrics and non-woven fabrics, which do not change significantly even when the structure or fibers change. Epoxy resin, urethane resin, neoprene, NBR, SBR,
Solvent type such as vinyl acetate, acrylic acid ester (reactive type, self-crosslinking type), NBR, SBR, emulsion type such as resin copolymer other than acrylic acid ester are also used. These adhesives are suitable when a stretch cloth made of polyurethane elastic yarn or the like is used as a base material.

The adhesive is applied to the base material by an undercoating device or the like. It is preferred to apply as little high viscosity adhesive as possible. When applying with a doctor knife,
A doctor knife having a thickness of at least 5 to 10 mm is preferable, and one having a slightly rounded shape (5 to 10 R) is better than an acute-angled blade edge. When the base material to which the adhesive is applied is water-permeable, if the back surface is lightly water repellent, the adhesive will not easily come out on the back surface. 8 times for drying after applying adhesive
Pre-drying at 0-100 ° C, surface temperature 100-13
Finish drying at 0 ° C can be adopted.

<Flocking Treatment> Basically, an ordinary electric flocking device and treatment conditions can be applied. A low-frequency high-voltage transmitter is generally used as the voltage pole. Usually output current 3-5mA
Is the range. The flight force of the electric flocked fiber material is proportional to the product of the product of the applied voltage and the output current. High voltage generator 1
The high voltage limit per unit is usually about 3.5 m ² .
The distance between the electrodes depends on the device structure and processing conditions,
For example, it is set to about 10 cm. As the high voltage, for example, 30 to 100 kV is applied. By adjusting the processing area, the flight characteristics of the fiber material can be adjusted.

<Splitting / Splitting Step> This is a process for branching the tip of the electro-implanted fiber material into a plurality of branches. Applicable to the fibrous tip cracking / splitting process of ordinary electric flocking products. It is possible to branch the tip of the monofilament, but the fused multifilament is more
Branching is easy. The fused multifilament is
Single filaments (filaments) that are fused and fused together
It is possible to crack and split the fibers by separating them individually. Electric flocking products are sheets,
If it is a film, it is preferable to use a raising machine composed of a plurality of cloth rolls, a polishing machine composed of brushing and rough surfaces, or a buffing machine.

The surface characteristics of the electric flocked product can be changed by the cracking / splitting process. Generally, the surface feels soft. Anti-slip property is also improved. Appearance becomes smooth in terms of design. [Electrical Flocking Product] Any product can be applied to various products as long as the appearance properties and characteristics of the surface by electric flocking can be utilized.
It can be applied to fabrics and sheet materials used for clothing and daily necessities. It can be applied to household products and building materials. It can be used as interior material for vehicles such as automobiles and aircraft.

More specifically, various uses and products listed below are classified according to the difference in the base material. A) Knitted woven fabrics, non-woven materials: Automotive applications (car seats, pillars, dashboards) Rugs (carpets, entrance mats, kitchen mats, bath mats, toilet mats, base materials for stair trimming tape, etc.) -Belts, table cloths, door knob covers, hook-and-loop fasteners) Footwear (insole insoles, socks, soles) Gloves (golf, sports such as baseball, agricultural, fishing and industrial work gloves) Construction Applications (roof base materials, conveyor belts) B) Plastic materials: Outdoor applications (boat departure and arrival piers, emergency stairs C) Metals, pottery materials: Figurines (base materials for table clocks, vases, pen stands, various decorations) D) Wood , Paper product furniture (sofa, socks for chairs) <Hook-and-loop fastener> The electric flocked product using the electric flocked fiber material of the present invention has a surface where surfaces are detachably joined. It can be used to Asuna. A surface fastener is a product that can be repeatedly joined and fixed or peeled off by pressing the surfaces together.

The electric flocked fiber material having the flocked surface of the base material has a high friction coefficient on the surface and exhibits elastic repulsive force when deformed. Therefore, if the surfaces of the electro-flocked products are crimped to each other so that the electro-flocked fiber materials are in contact with each other and meshed with each other, when the electro-flocked products are attempted to be peeled off, Large frictional resistance occurs and cannot be easily peeled off. When the surfaces of the electric flocked products are pressure-bonded to each other, the electric flocked fiber material is elastically deformed, or the electric flocked fiber material is deformed by a force for peeling the electric flocked fiber materials,
By the elastic repulsive force against it, the electric flocked fiber materials are pressed against each other, and the above-mentioned frictional resistance becomes larger.

As a result, the pressure-implanted electric flocked products are bonded and fixed to each other. Of course, by applying a peeling force that exceeds the friction resistance of the electric flocked fiber material, the electric flocked product can be separated, and fixing and separation can be repeated. Functions as a surface fastener. The electric flocked fiber material used for the electric flocked product to be a surface fastener has a length of 1.5 to 10 mm and a thickness of 420 to 2,500 d.
A tex and a linear yarn having an aspect ratio of 1.5 to 8.5 are preferable because the function as a surface fastener can be exhibited well. A flexible sheet material is used as the base material. The above-mentioned knitted fabric, non-woven fabric, synthetic resin sheet, etc. may be mentioned.

With respect to the form and method of use of the surface fastener, the same technique as that of a normal surface fastener can be applied. As specific applications, in addition to clothing, for transporting and moving various items,
It can be applied for fixing. As the form of the hook-and-loop fastener,
There are tape-shaped ones and sheet-shaped ones with a relatively large area. You can use it to fold and close one loop fastener with the flocked surface inside. It can be used as a closure for clothing buttons and zippers. It is also possible to combine and use two surface fasteners. In this case, it is also possible to use a combination of electric flocked products having different types and structures of electric flocked fiber materials. It is possible to adjust the joining force and the workability of attachment and detachment by combining the electric flocked fiber materials.

BEST MODE FOR CARRYING OUT THE INVENTION [Electrical Flocked Fiber Material] The electric flocked fiber material 30 shown in FIG. 1 (a) is a straight yarn made of monofilament of polyurethane elastic fiber. In the figure, the cross section is represented as a perfect circle, but it does not have to be a perfect perfect circle in practice. Depending on the spinning method, some fibers have an elliptical shape or unevenness. The end surface of the fibrous material 30 is orthogonal to the axial direction and has a sharp cut surface with a right edge. However, actually, the end faces may be inclined with respect to the axial direction, or the corners may be slightly rounded.

The electric flocked fiber material 30 shown in FIG.
It is a straight yarn made of fused multifilament of polyurethane elastic fiber. The fibrous material 30 is joined and integrated with each other in a state where a plurality of linear filaments 32 are aligned in parallel. The figure schematically shows a state in which seven filaments 32 are evenly attached so that the entire filament is rounded. However, as the attachment filament, the one having an oval shape, an oval shape, or another shape may be used. In some cases, the filaments 32 are arranged in parallel in one row or in a plurality of rows on the same surface. In the electro-implanted fiber material 30 composed of fused filaments shown in FIG. 1C, a large number of filaments 32 are fused in an indefinite shape, and there is also a portion with a gap between the filaments 32. .

[Electrical Flocking Product] In the electric flocking product shown in FIG. 2, the electric flocked fiber material 30 is electrically flocked on the base material 10 via the adhesive layer 20. The base material 10 is made of a knitted fabric. As the adhesive layer 20, for example, a mixture of epoxy resin and urethane resin in the range of 20:80 to 80:20 can be used. Mainly vinyl acetate emulsion (10
It is also possible to use PVA or a highly condensed urea resin added in an amount of 10 to 15 parts or 30 to 50 parts. The electric flocked fiber material 30 is a straight yarn made of a monofilament of polyurethane elastic fiber. The fiber material 30 is
In the state of being anchored to the adhesive layer 20, the hairs are planted in an upright state on the surface of the base material 10 and arranged in parallel with each other. The fibrous material 30 pierces to the bottom portion of the adhesive layer 20, and the bonding area between the fibrous material 30 and the adhesive layer 20 is large and they are firmly joined. The uprightness of the fiber material 30 is also high. In the figure, the intervals between the fibrous materials 30 are shown to be uniform, but in practice, the intervals may vary within a certain range.

[Fractured Tip Flocked Product] The electric flocked product shown in FIG. 3 has basically the same structure as the flocked product of the above embodiment, but the electric flocked fiber material 30 is different. As the fiber material 30, a fused filament as shown in FIGS. 1B and 1C is used. In addition, after the electric flocking step, pre-splitting is performed, and the individual filaments 32 that have been coalesced are separated at the tip of the fiber material 30. As a result, the surface of the electric flocked product is in a state where the fine filaments 32 are closely arranged, and the surface texture gives a soft impression. The actual touch is extremely soft. Fiber material 30
Has a large coefficient of friction on the surface, and thus has improved slip resistance. In particular, it can exhibit a high anti-slip function even in a wet state.

Since only the tip of the fibrous material 30 is pre-cracked, the root portion of the fibrous material 30 maintains the required rigidity, and the uprightness of the whole is not impaired, and the elasticity of the fibrous material 30 when the load is applied is maintained. It also has good resilience and resilience after unloading. [Insole] The insole 40, which is the insole material of the shoe shown in FIG. 4, uses the electric hair transplant product of the present invention. Figure 4
As shown in (a), the insole 10 is arranged on the surface side in contact with the sole of the foot in a state in which the electric flocked fiber material 30 is densely packed over the entire surface, and the fiber material 30 is an adhesive layer (not shown). It is supported by the base material 10 via.

As the electric flocked fiber material 30, a polyurethane elastic fiber monofilament or a fused multifilament having a length of 7 mm or less and a thickness of 420 to 2,500 dtex is used. A knitted woven fabric or a non-woven fabric is used as the base material 10. In the case of knitting, a cardboard knit of circular knitted fabric or a three-dimensional structure of double Russell can be adopted.
Double woven fabrics can also be used. It is also possible to use a non-woven fabric and a woven fabric bonded with a moisture permeable film. In order to improve the sanitary environment in the shoes when used, those that have been subjected to antibacterial / deodorant processing or coated with Bincho charcoal, bamboo charcoal, etc. can also be used.

As shown in FIG. 4 (b), the insole 40
On the back surface of the base material 10, the base material 10 has a concavo-convex shape 42 that conforms to the concavity and convexity of the sole. Such a concavo-convex shape may be obtained by performing a shaping process on the base material 10 in advance and then flocking the fibrous material 30, or by applying a concavo-convex shape to a flat electric flocked sheet by pressing or the like. May be. It is also possible to manufacture a flat insole 40 having no uneven shape so that it deforms along the shape of the foot while it is being used. The insole 40 of the above-described embodiment can favorably prevent the foot from slipping and moving or being biased in the shoe when the shoe is attached to the shoe and used. In particular, even when rain penetrates into the shoes or sweats, the water does not slip easily. Even if the fiber material 30 is deformed by the pressure of the foot during walking, the fiber material 30 quickly and elastically restores to its original state after walking, and uniform surface smoothness can be maintained. It is possible to solve the problem that the fiber material 30 is permanently deformed eccentrically due to a difference in weight suspension, a partial dent or a hair collapse is caused, and a feeling of contact with a foot or a cushioning property is impaired. The fine irregularities at the tip of the fiber material 30 can also be expected to have an effect of promoting health by stimulating the acupoints on the soles of the feet.

[Golf Gloves] A golf glove 50 shown in FIG. 5 uses the electric flocking product of the present invention. The golf glove 20 uses an electric flocked product for the palm piece 52. The electric flock cloth used as the material of the palm piece 52 is the base material 1
As 0, a stretchable base fabric can be used. As the stretchable base fabric, interlocks using polyurethane elastic fiber yarn, bare knitted fabric circular knitted fabric, 2-weight licot, covered elastic yarn interlaced weft insertion tricot, and the like can be used. The electric flocked fiber material 30 has a length of 3 mm or less and a thickness of 22 to 940 dte.
x polyurethane elastic fiber monofilaments or fused multifilaments are used. In the case of coalesced multifilaments, first splitting and splitting treatment are performed.

The back piece 5 of the hand may be made of the same material as that of the palm piece 4, or is made of the same artificial leather as that used for ordinary golf gloves. In the above embodiment, the golf glove 50 having an excellent anti-slip function can be obtained. Compared with leather gloves that are generally used in the past, the slip resistance in the case of rainfall is significantly improved. Conventionally, a rubber-coated glove for slip prevention is also known, but the golf glove 50 has the drawback that it tends to get stuffy when worn.
Then, the breathability is improved and the wearing feeling is also improved. In the above embodiment, as the fibrous material 30, fine powder having a thickness of about 22 dtex or less can be used instead of the straight yarn of the above embodiment.

The golf glove 50 may be subjected to, for example, water repellent processing, raised processing, punching processing with air permeability, bonding processing with a stretchable knitted material, or the like. [Hook-and-loop fastener] The hook-and-loop fastener 60 shown in Fig. 6 is made of an electric flocked product. The surface fastener 60 includes a tape-shaped base material 10 made of a woven or woven fabric, with an adhesive 20 interposed therebetween,
An electric flocked fiber material 30 made of a straight line of polyurethane elastic fiber monofilament or fused multifilament is electroflocked. Fiber material 30 used here
Has relatively long fiber length and rigidity.

When the surfaces of the tape-shaped surface fasteners 60 are faced to each other and pressure-bonded, the electric flocked fiber materials 30 projecting from each other are inserted into the gaps of the electric flocked fiber materials 30 on the mating side to engage with each other. To be The side surfaces of the electric flocked fiber material 30 contact each other. When the electric flocked fiber material 30 is elastically deformed, a frictional resistance force is generated on the contact surface of the electric flocked fiber material 30. As shown in FIG. 6, when the surface fasteners 60 in the joined state are to be peeled off from each other, a large frictional resistance force is generated between the electric flocked fiber materials 30 that are in contact with each other on the side surface. Further, when the fiber material 30 is elastically deformed by being bent or pulled, the restoring force causes the fiber materials 30 to be excessively pressed against each other, and a resistance force against peeling is generated.

As a result, the surface fastener 6 once joined
The 0s do not spontaneously separate, and do not separate even if they are pulled a little. Then, when the surface fasteners 60 are separated from each other by applying a certain amount of force or more, the fiber material 30 is pulled out from the gap between the fiber materials 30 on the mating side, and the surface fasteners 60 are separated from each other. At this time, since it suffices that the fibrous materials 30 made of the straight yarns are slid together, the hook hook catches on the hook hook like a conventional hook hook type surface fastener, making it difficult to peel off or causing an unpleasant peeling noise. Does not occur. Also, the durability is good.

As a specific application of the surface fastener 60, it can be used as a fold-back surface fastener which is used in place of shoelaces, such as shoes for infants to school children and shoes for nursing care. Even relatively weak users can easily attach and detach. The hook-and-loop fastener 60 can be used as an inside belt attached to the inside of the waist of golf pants or casual slacks. In this case, the surface of one surface fastener 60 comes into contact with shirts or the like to prevent slipping. Since the fibrous material 30 is deformed flexibly, the feeling of contact with the body is good. Make the loop fastener 60 annular,
It can be used as a leg band or arm band. The flocked fiber material 30, which can be elastically deformed, flexibly abuts against the movements of the user's legs or arms, and effectively fulfills the function of preventing slipping. Similarly, when used as an adjustment band for a hat, it is possible to effectively prevent uncapping in a capped state.

The weight (W) of the fiber material dropped from the mesh is measured 5 times (50 rotations per minute), and the mesh pass ratio (%) is calculated by the following formula.

Mesh pass rate (%) = W / 10 × 100 (2) Appearance quality of the flocked product Whether the flocked length of the flocked product with flocked is uniform or the flocked density has no unevenness is visually determined. The judgment was made in the following 5 steps. (3) Evaluation of hair fall resistance of flocked product A 5 cm x 5 cm plastic underlay is laid on the surface of the flocked flocked product, 1 kg of weight (weight) is placed on it, and after 24 hours, it is unloaded and left for another 30 minutes. Then, the piled shadow was visually evaluated according to the following three levels.

Lower level: fall pile is not recovered, trace type is conspicuous Intermediate level: fall pile is not restored, trace type can be judged Advanced: fall pile is restored, trace type is invisible (4) Flocking Evaluation of napped texture and softness of the product As a texture of the napped surface of the flocked product, a compression elasticity tester (made by Maeda Seiki) having a thickness gauge with an area of 4 cm ² is used.
The change rate (%) of the displacement amount under a constant pressure of 4.9 kPa (50 gf / cm ² ) and 10 seconds was used to judge in the following three stages. Large: Amount of change in displacement of 21% or more, extremely soft feel Medium: Amount of change in displacement of 6 to 20%, Slight feel of soft: Small amount of change in displacement of 5% or less, hard feel (5) Evaluation of anti-slip properties of flocked products 20 cm x 2 on a mirror-finished flat glass placed on a horizontal surface
