Description

[Detailed description of the invention]

The present invention relates to a method and apparatus for manufacturing stretch cloth products by applying a silicone rubber compound onto the surface of a stretch cloth. The method is characterized in that the silicone rubber compound is pressed onto the surface of the stretchable fabric while it is uncured (including in a semi-cured state) to produce a cured silicone rubber with a rough surface. Further, the present invention has good dry cleaning resistance,
After curing, we provide a stretchable fabric product that has effective frictional properties that do not increase in hardness and undergo wear and tear over time such as arming, cracking, or discoloration, and that does not give a foreign body feeling and prevents curling up. be. Conventionally, the methods for applying a thin layer of silicone rubber compound to the surface of various fiber cloths include (1) dissolving silicone rubber in a suitable volatile solvent and soaking the fibers in the resulting solution; The following methods are widely used: (1) applying a non-flowing or low-viscosity silicone rubber compound to the fibers using a doctor knife, and (3) applying by screen transfer. When applying a silicone rubber compound to a stretchable fabric in a thin layer with a rough surface and curing it, considering each of the above methods, method '1' is a synthetic fiber product that is resistant to solvents. In addition, method '2] applies tension to the uneven stretchy fabric using a knife, causing "wrinkles" and "distortions" on the stretchy fabric. In addition, the glue method requires the use of a silicone rubber compound that is non-flowable or has poor flowability, and it penetrates into the gaps between the fibers of the stretch fabric to form a thin layer with good adhesion. The disadvantage is that it is difficult to

Both methods [2] and [3] have the disadvantage that the frictional effect is low because the surface of the silicone rubber after curing is smooth. On the other hand, many stretchable fabric products have anti-slip and stretchable functions because they are used to provide anti-slip properties to the human body and textile products, such as pants, skirts, and underwear. This is requested. In such cases, various techniques have been used to provide effective frictional properties. For example, methods have been used in which polyurethane or other elastic polymers are applied to cloth in various patterns, or the stretchable weave is made of a woven cloth having an uneven surface. However, this method lacks dry cleaning resistance, which is an essential requirement for clothing, and increases hardness, cracks, discoloration, and scratches over time during use, resulting in a decrease in anti-slip function and mechanical strength. There are disadvantages in that it may cause a decrease in performance and a sense of discomfort. In addition, the uneven pattern may give the impression of a foreign body. Furthermore, the product tends to roll up in the areas where the elastic fabric is provided with a non-slip function, which is likely to cause problems with the original anti-slip function. This is particularly noticeable in the case of weak decorative tapes for foundations. Furthermore, when silicone rubber is applied to fabric products in various patterns, simply applying it by flowing it down from a nozzle or injection needle will only provide a smooth surface and will not be sufficient. It is difficult to obtain a fabric product with an anti-slip effect, and since it is poorly compatible with fibers, it tends to peel off during dry cleaning, washing, repeated rubbing, etc. In particular, the fact that it does not have an anti-slip effect is a serious drawback when used for clothing such as skirts, as mentioned above. In order to improve this point, the present invention applies a curable silicone rubber compound with an appropriate viscosity range to a stretchable cloth, and then presses it onto the surface of the stretchable cloth in an uncured or semi-cured state using a roll. By curing it into a rough, thin layer and providing a silicone rubber layer with good adhesion to stretchable fabrics, it has good dry cleaning resistance and increases hardness over time, causing cracks, discoloration, and scratches. The purpose of the present invention is to provide a stretchable fabric product having effective frictional properties without friction. That is, the main components of the present invention are polyorganosiloxane, a crosslinking agent, and an inorganic filler. A silicone rubber compound with a viscosity of 20,000 to 250,000 centipoise at 25 qo and a time when the surface becomes sticky within 10 minutes is applied to the surface of the elastic cloth in a thin layer, and the silicone rubber compound is rolled in an uncured or semi-cured state. A method for manufacturing a silicone-coated stretchable fabric product, which is characterized by forming a silicone rubber layer with a rough surface on the surface of the stretchable fabric by compressing and stretching the stretchable fabric and then curing the fabric, and curing the fabric. Apparatus for applying and stretching a silicone rubber compound on the surface of an elastic fabric so that the subsequent surface is a rough, thin layer, comprising means for applying a silicone rubber compound on the surface of the elastic fabric; The present invention relates to an apparatus comprising means for stretching a silicone rubber compound while pressing it onto the surface of a stretchable cloth with a roll, and means for curing the stretched silicone rubber compound. The silicone rubber compound used in the present invention is mainly composed of polyorganosiloxane, a crosslinking agent, and an inorganic filler, and the curing method differs depending on the combination of polyorganosiloxane and crosslinking agent, but it is compatible with textile products. From the viewpoint of workability and properties of the uncured silicone rubber compound, a silicone rubber compound that cures at room temperature is recommended, but a silicone comb compound that has a curing temperature of up to 10,000 ℃ may also be used. Although the curing mechanism of these materials differs depending on the combination of polyorganosiloxane, crosslinking agent, and curing catalyst, curing is promoted by addition of a curing catalyst, heating, or humidification. The first condensation type room temperature curable silicone rubber compound is generally polyorganosiloxane.

Carboxylate salts of metals from lead to magnesium are used in In particular, methyl groups are preferred as RI and R2 from the viewpoint of ease of production and balance of physical properties after curing. Also, × is
An acetoxy group is preferred from the viewpoint of ease of obtaining a good curing time. In addition, a value of 50 to 5000 is selected as n because the necessary physical properties cannot be obtained if n is less than 50.
000 or more, the viscosity of the silicone rubber compound deviates from the required range. Furthermore, if a exceeds 1.9, it will not be possible to obtain a silicone rubber that is cured and has appropriate rubber elasticity. In the second addition-type cold-curing silicone rubber compound, the polyorganosiloxane has the general formula R3Si. [R stem Si. ]mSiR3 (wherein R3 is a monovalent hydrocarbon group, of which the molecule contains at least two pinyl groups, m is a number from 50 to 5000), and the crosslinking agent is of the average formula [R Kikkatsu CSi. 4 One trick/C]X (However, R4 is a monovalent hydrocarbon group, b is 1 to 3, and c is 0

Also, unless there are at least three hydrogen atoms directly bonded to silicon in the crosslinking agent molecule, it will not be possible to cure and obtain a rubber-like elastic body. The value of 50 to 5000 is selected as the range of m for the same reason as the selection of n in the condensed type. Further, from the viewpoint of ease of production, it is preferable that the remainder of R3 excluding the vinyl group and R4 are each a methyl group. The inorganic filler used in the present invention may be any one used in ordinary silicone rubber, such as silica, carbonate, calcium carbonate, and carbon black. Reinforcing fillers such as fumed silica and precipitated silica are used. Furthermore, non-reinforcing fillers, pigments, etc. may be added to this. Further, a processing aid, an adhesion improver, a flame retardance improver, etc. can be used in combination as appropriate. The major characteristics of the silicone rubber compound used in the present invention are that it has a viscosity of 20,000 to 250,000 centipoise at 25°C and has suitable flow properties and hardening properties such that the surface becomes non-stick in less than 10 minutes. It is. The reason why an appropriate viscosity range and curability are required is that the silicone rubber compound applied to the surface of the elastic fabric, which is a feature of the present invention, is rolled in an uncured or semi-cured state that retains stickiness and high viscosity. When the silicone compound is peeled off from the roll by pressing it against the surface of the elastic cloth,
Because of its adhesiveness and high viscosity, it peels off while forming an uneven surface, and hardens while maintaining the same surface shape, thereby forming a thin layer with a rough surface. That is, the viscosity at 2500 is 2000
If it is less than 0 centipoise, the silicone rubber compound will loosen into the fiber gaps of the stretch fabric and easily flow, spilling out onto the back side of the fabric. Even if a semi-cured surface with fine irregularities is formed when pressed against the surface, due to its fluidity, it will flow out within the time it takes to harden and obtain a thin layer of silicone rubber.
Due to the formation of a hardened smooth surface, a rough surface with effective friction properties is not obtained. On the other hand, 250
If the viscosity at zero exceeds 250,000 centipoise, the silicone rubber compound will clog the nozzle or transport pipe, making it difficult to apply the silicone rubber compound quantitatively, leading to the interruption of the application. It is also unfavorable in terms of adhesion and disadvantageous in terms of anti-slip function and try-cleaning resistance. 20000-25 mentioned above
After a silicone rubber compound having a viscosity in the range of 0,000 centipoise is pressed onto the surface of a stretchable fabric, the time required for the silicone rubber compound to harden and become non-flowable is less than 1000 centipoise. This is because the silicone rubber compound penetrates into the gaps between the fibers of the stretchable fabric, and a good adhesive condition is obtained between the silicone rubber and the fabric after curing. This is a necessary condition for obtaining a thin layer of silicone rubber with a rough surface, without causing the surface to become smooth due to excessive flow of the compound. The physical properties of the completely cured silicone rubber are not particularly limited, but preferably have a hardness of 15 to 50 according to JIS K6301, a tensile strength of 15 k9/h or more, and an elongation of 200% or more. If the physical properties are outside of this range, good friction properties and dry cleaning resistance will not be obtained, and hardness will increase, cracks, etc. will occur during use.
Easy to cause chafing. That is, if the hardness is less than 15, the durability and abrasion resistance during use will be poor, and if the hardness exceeds 50, it will be too hard and give an uncomfortable feeling, and the tensile strength will be 15k9/
In quenching, the physical properties change greatly over time, and the elongation is 200%.
%, the elastic fabric cannot deform during use and is likely to peel off. The stretchable fabric used in the present invention is selected from fabrics with a stretchable structure such as woven fabrics, coarse cords, and knitted fabrics, and is preferably in the form of a tape, but it may be cut to the width of clothing or a raw material. But that's fine. Furthermore, since no solvent is used when applying the silicone rubber compound, materials with poor solvent resistance are also acceptable. In other words, examples of such stretchable fabrics include fabrics made from any natural fibers, recycled fibers, semi-synthetic fibers, and synthetic fibers that have been made to have elasticity depending on how they are spelled, and fabrics such as rubber thread and spantex. It has elasticity by blending it with a stretchable material. Further specific examples include polyester-spandex blend fabric, nylon-spandex blend fabric, rayon-spandex blend fabric, cotton-spandex blend fabric, polyester-rubber thread blend fabric, nylon-rubber thread blend fabric,
There are rayon-rubber yarn blend fabrics, cotton-rubber yarn blend fabrics, various bias tapes, and Helanka (Kanebo product name) tape. However, these examples do not limit the scope of the present invention. Next, the present invention will be explained with reference to the drawings.
FIG. 1 is a partial plan view of a novel stretchable fabric article according to the present invention. Figure 2 shows Figure 1 A- of the stretchable fabric product of the present invention.
It is a sectional view taken along the line A'. FIG. 3 is a schematic side view of an apparatus for carrying out the method for manufacturing stretchable fabric products of the present invention. 1 and 2, a room-temperature curing silicone rubber compound is applied to one side of a base elastic fabric 1 and stretched, resulting in a thin layer of silicone rubber with a rough surface, as shown in FIG. form. If woven fabric is used, 1 inch (25.
It is suitable to have 25 to 200 threads per inch (4 sides) and 25 to 200 threads per inch (25.4 ribs) in the weft direction as well. This stretchable fabric may be subjected to permanent pressing, wash and drying, resin finishing, or other fiber finishing processes, if desired. However, the fabric must not be treated in a way that would prevent the silicone rubber compound from adhering to the stretch fabric. FIG. 3 shows a conceptual diagram of an apparatus for carrying out the method of the present invention. In this device, an untreated stretchable fabric 3 is fed to a belt 5 in an unstretched Z state through a stretchable fabric supply device 4. The belt is made of relatively hard cloth or felt, etc.
A material is chosen that does not sag and does not cause the elastic fabric to slip on it. In this case, if the V-supply device 4 is not passed, the stretchable cloth will be pulled on the belt 5, which will change the amount of silicone rubber compound applied per unit length in the Z direction, resulting in uneven coating, which is undesirable. The elastic fabric is led by a belt 5 under a head 6 for applying silicone rubber compound. The head 6 is connected to a plurality of nozzles 7 or other means for supplying the silicone rubber compound to the elastic fabric and, if desired, drives the head perpendicularly to the fabric belt 5 at a constant speed or in a reciprocating harmonic manner. It has a device 8. The room temperature curable silicone rubber compound is stored in a storage tank 9 in an uncured state. Note that the silicone rubber compound may have the above three properties depending on the combination of organopolysiloxane, crosslinking agent, and curing catalyst.
Some types of components or organopolysiloxanes and crosslinking agents can be cured depending on the case, some can be accelerated by heating after mixing, and some can be made by mixing the three components with the green component blocked, and can be cured by moisture in the air. There are some that harden upon contact with, and the structure of the storage part differs accordingly. As an example, Fig. 3 shows a method applied to a material that is cured by moisture in the air, but it is applicable to a material that is cured by mixing multiple fluids, although it is omitted in Fig. 3. A storage tank corresponding to the number of fluids, a metering pump and a mixing device appropriate to the fluidity and blending amount are required. The storage tank 9 is isolated from the atmosphere by the packing 101 to prevent moisture from entering. The silicone rubber compound is pumped up from the storage tank 9 and passed through the transport pipe 12, valve 13 and transport pipe 14 to the head 6.
and applied to the elastic fabric by a nozzle 7 or similar means. If desired, the valve 13 can also be opened and closed at regular time intervals, and this, together with the movement of the drive device 8 of the head, causes the application of silicone rubber cosopound in a regular pattern on the surface of the elastic fabric, if desired. It is also possible to do so. The amount of coating is not particularly limited, but the weight of each Usinuri 2 in Figures 1 and 2 is 0.1.
~39/ It is appropriate to make it as follows. The stretchable cloth coated with the silicone rubber compound is transferred by the belt 5 to the bottom of the presser roll 15, where the silicone rubber compound is pressed onto the surface of the stretchable cloth by the presser roll 15 in an uncured or semi-cured state. , is expanded. At that time, the hardened or semi-hardened silicone rubber compound that is peeled off from the roll forms a finely uneven surface due to its adhesiveness and high adhesiveness.
It hardens without flowing, forming a rough surface and adhering tightly to stretchable fabrics. The pressure required for this crimping and stretching is kept constant by the pressing device 16. Since the presser roll 15 rotates in conjunction with the movement of the cloth belt 5, the stretchable cloth will not be stretched, sagged in front of the roll, or wrinkled or distorted. Further, although this portion of the belt 5 is not shown in FIG. 3, if a roll or iron plate is provided on the back side thereof, the belt 5 will not be bent by the pressure roll. The applied, crimped and stretched silicone rubber compound preferably has a thickness of about 0.5 to 3
Leave at room temperature for a minute. The stretch fabric is then led to a vulcanizer 17, where the silicone rubber compound is cured. The vulcanizer 17 has a drum 18
and a guide roll 19, around which the stretchable fabric is wound in a helical manner. In order to accelerate curing, a heating device 20 and/or a humidifying device 21 may be provided in the vulcanizer 17 as necessary. Further, a device 22 for removing volatile substances generated during curing may be provided. Curing of the silicone rubber is usually carried out at a temperature of about 50 to 2000°C, and if necessary, for about 5 to 30 minutes in an atmosphere with a relative humidity of 60% or more. After the silicone rubber compound has hardened to become a thin layer of silicone rubber with a rough surface, the stretchable fabric is pulled out from the vulcanizer 17 by pull-out rolls 23 and 24 and housed in a pith 25 or a cardboard case. After the volatile substances generated by the curing reaction are dispersed if necessary, the material is inspected and wound onto a spool or bobbin. Note that the presser roll 1 in an uncured or semi-cured state
During the period from the application in step 5 to the hardened draw-out roll 23, care is taken not to press down on the silicone rubber compound coated surface of the stretchable cloth. The silicone-coated elastic fabric products manufactured in this way have excellent anti-slip properties, and do not increase in hardness or crack over time during use.
It has excellent washing resistance, dry cleaning resistance, and abrasion resistance, and maintains flexibility between -60°C and 25,000°C. Therefore, this silicone-coated elastic fabric product can be used in trousers, skirts, sportswear, etc. in tape or fabric form.
It is extremely useful as a non-slip device for girdles, brassieres, and gunte east fittings. Examples of the present invention are shown below. In the examples, all parts refer to parts by weight. Example 1 75 parts of polydimethylsiloxane with a molecular weight of 60,000 with both ends blocked with hydroxyl groups, and 2 with polydimethylsiloxane with a molecular weight of 2000 with both ends blocked with trimethylsilyl groups.
A silicone rubber having a viscosity of 120,000 centipoise at 25° C. is prepared by uniformly mixing 5 parts of silica, 6.0 parts of methyltriacetoxysilane, and 0.05 parts of dibutyltin diacetate. A compound was prepared. Using the apparatus shown in Fig. 3, a thin layer with a rough surface and a maximum thickness of 0.4 cm is applied to various elastic cloths in two widths, and cured at a temperature of 6500℃ and a relative humidity of 60%. After being left in the air for 24 hours to complete curing, the layers were directly touched to compare their anti-slip properties. The results are shown in Table 1. Table 1 Example 2 7 parts of polydimethylsiloxane monool with a molecular weight of 90,000 with both ends capped with hydroxyl groups, 3 parts of polydimethylsiloxane monool with a molecular weight of 1500 with one end capped with a trimethylsilyl group, surface area 200 parts/day. A silicone rubber having a viscosity of 170,000 centipoise at 250 mm was prepared by uniformly mixing 1 part of fumed silica, 2.0 parts of diisopropoxydiacetoxysilane, 5.0 parts of methyltriacetoxysilane, and 0.06 parts of dibutyltin diacetate. A compound was prepared. This silicone rubber compound was applied onto various elastic woven fabrics using the apparatus shown in Figure 3, crimped and stretched, cured at a temperature of 65 qo and relative humidity of 60%, and left in the air for two hours until the surface became smooth. A rough silicone rubber layer with a maximum thickness of 0.4 ribs and a width of 2 skins was formed on the surface of the stretchable woven fabric. As a comparative example, the above-mentioned silicone rubber compound was applied smoothly to various elastic woven fabrics to a thickness of 0.4 skin and width of 2 skin without pressure bonding with a roll, and cured under the same conditions. These samples were tested and compared for dry cleaning resistance, washing resistance, abrasion resistance, and repeated expansion and contraction fatigue resistance under the following conditions. The results are shown in Table 2. a Dry cleaning resistance Take a test point at 10 intervals in the center of a sample with a length of 30 skin, place it in a Landau Meter test bottle with two stainless steel balls, and place it in a test bottle of Perchlorethylene 100 that conforms to JIS K1521. After adding '' and operating for 30 minutes at a temperature of 30±2°C, the sample was taken out and hung indoors, dried, and the condition of the sample and the interval between gauge points were observed. b. Washing resistance: Take a gauge mark at a distance of 20 mm in the center of a sample with a length of 50 cm, and use a household washing machine to add 25 cm of powdered neutral detergent to 2 cm of water.
After washing for 15 minutes at a temperature of 40±2°C in a solution containing 5.5% water, change the water, rinse for 18 minutes, dehydrate for 1 minute, and hang the sample indoors to dry. Observe the gauge line spacing. c Using a Gakushin type friction tester type O for repeated abrasion resistance and color fastness testing, cover the tip of the friction element with a dry white friction wire cloth that conforms to JISK 0803, apply a load of 250 mm, and place on the test stand. 10 in the direction perpendicular to the silicone line on the specimen fixed above.
After performing 100 reciprocating frictions between the skin at a speed of 30 times/min (reciprocating), the condition of the sample is observed. d Repeated stretching/stretching fatigue resistance: Take a sample with a length of 10 skin and apply 30% at a rate of 130 times/min.
Repeat stretching. First, the sample is stretched 50,000 times, and if the applied silicone peels off, it is further stretched 20,000 times, and if it does not peel off, it is stretched 100,000 times, and the condition of the sample is observed. 2nd whistle ◎: Very good ○: Good △: Partially defective

By uniformly mixing, a silicone rubber compound liquid A was prepared. On the other hand, liquid B was prepared by mixing 1 part of the above-mentioned methylvinylsiloxane unit-containing polydimethylsiloxane and 1 part of 1,3,5,7-tetramethylcyclotetrasiloxane.

This is a room-temperature-curing silicone rubber compound with a viscosity of 200,000 centipoise at zero temperature, but if left as is, the viscosity will increase and it will harden, so it is stored separately until use. Instead of the storage tank part of the device shown in Figure 3, two storage tanks, a metering pump, and one mixing head are connected through a transport pipe, and liquids A and B are mixed at a weight ratio of 3:1. In the same manner as in Example 1, except that the coating head is fed while mixing quantitatively, a thin layer with a rough surface and a maximum thickness of 0.6 mm and a width of 2 arcs is applied to the surface of various elastic cloths. After curing at a temperature of 10,000 for 5 minutes, dry cleaning resistance, washing resistance, repeated abrasion resistance, and repeated stretching and contraction fatigue resistance were tested in the same manner as in Example 2.
