Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides pile fibers made of continuous fibers by planting pile fibers made of continuous fibers on the surface of a base fabric made of woven, knitted or non-woven fabric using a jet stream. The present invention relates to a method and apparatus for producing pile fabrics, and more specifically, a method and apparatus for producing animal hair-like fabrics similar to marten, mink, etc., pile fabrics as a material for inchinriya materials, industrial coated blankets, etc. It is related to.

[Prior Art] Conventional methods for obtaining pile fabrics include the following.

(1) A method in which pile threads are woven into the fabric during weaving, and the yarn is raised after weaving.
This includes towels, carpets, and Mll.

(2) Electrodeposition method in which a base fabric is placed in a high-voltage electrostatic field and flocked flocks (rectangular fibers) are flocked onto it under the action of static electricity.

(3) When knitting a knitted fabric using the sliver knitting method, a bundle-shaped am aggregate (so-called sliver) with fibers aligned in the length direction is supplied to the knitted fabric as napped fibers,
How to knit these at the same time and style the hair after knitting.

However, these conventional methods have the following drawbacks.

In the method (1) above, in which the pile fibers are woven into threads, the pile fibers are used in the form of threads, so the pile fibers must have spinnability in terms of spinning, and the fiber length, Fineness, surface characteristics, etc. are limited, making it impossible to obtain products with diverse performance.

In the electrodeposition method (2), since the pile (flock) is flocked by electrostatic force, the fiber length and fineness are limited to a relatively small range. Furthermore, due to the effect of electrostatic force, there are technical difficulties in applying conductive fibers such as metal fibers and carbon fibers.

Further, in the method (3), it is necessary to form the pile fiber into a sliver shape, and the pile fiber needs to have spinnability. Therefore, the fiber length and thickness are restricted, and the fiber length is usually in the range of 30 to 80 mm and the fineness is in the range of 3 to 10 deniers.

Furthermore, since the ground structure is a knitted structure, there are problems such as a weak pile holding force and an inability to increase the density of the pile.

[Problems to be Solved by the Invention] In contrast to the above-mentioned conventional techniques, the present invention solves the problem of using any base fabric prepared in advance, regardless of the weaving or knitting of the base fabric, that is, the weaving or knitting of the base fabric. An object of the present invention is to provide a method and apparatus for producing pile fabrics, which can be flocked with pile fibers, have no major restrictions on the shape, properties, etc. of the pile fibers, and can use a wide range of continuous fibers. In particular, a method and apparatus for producing a pile fabric that can be firmly supported by the ground structure even if the fiber has one smooth surface and is not spinnable (e.g., carbon fiber, glass fiber #1). This is what we are trying to provide.

Means for Solving Problem E] In order to achieve the above objects, the method for manufacturing pile fabric of the present invention provides a method for producing pile fabric made of continuous fibers unwound from a bobbin on the surface of a base fabric made of woven, knitted or non-woven fabric. Hold the ends of the fiber rows and apply 100 k to this pile fiber.
By applying a high-pressure fluid of the order of 1 g/cm or more as a jet with a diameter of about 1 l or less, the jet is relatively moved along the base fabric surface in a direction intersecting the pile fibers. , a part of the pile fibers subjected to the jet action penetrates into the base fabric, and at the same time entangles with the fibers constituting the base fabric, thereby extending the planted planting area AM row to the next adjacent one. The fiber row for pile is tilted to the side opposite to the planting position, and the fiber part to be planted next is brought out onto the planting position, and planting is performed by the jet flow, and this is repeated to form a pile fabric. It is characterized by manufacturing.

Further, the apparatus of the present invention includes a base plate on which a base fabric is placed, a fiber guide means for guiding a pile fiber row unwound from a bobbin onto the surface of the base plate, and a fiber guide means for guiding a pile fiber array unwound from a bobbin onto the surface of the base plate, and a pile fiber array arranged on the base plate. A nozzle with a small diameter of about 1 m layer or less that applies a high pressure fluid of the order of 100 kg/cm2 or more to the fibers,
A two-dimensional moving device capable of relatively moving the nozzle along the base fabric surface in a direction intersecting the pile fibers, and also relatively moving the nozzle in a direction intersecting it for the next flocking. By engaging and pushing the fiber row led out on the base plate, the planted fiber row planted on the base fabric is placed in the opposite direction from the adjacent fiber row planting position for the next pile. It is characterized by comprising a fiber operating rod that is tilted to the side and guides the fiber portion to be planted next onto the planting position.

The pile fabric manufactured by the present invention uses various synthetic fibers that are continuous fibers as pile fibers, and if necessary, thick and short tIAm is planted between them to support the thin and long fibers. By having such a structure, it can be made into a high-quality animal hair-like artificial fabric, which can be used for clothing and various other uses.

In addition, fabrics in which pile fibers with a relatively large fineness are flocked are acceptable as materials for indoor use such as rugs.

Furthermore, fabrics in which organic fibers, inorganic fibers, metal fibers, etc. are flocked in short lengths on a strong base fabric are used as industrial New Year materials.

In the pile fabric produced by the method or apparatus of the present invention described above, the pile fiber is a solid or hollow synthetic fiber such as nylon, polyester, or polyamide, depending on the use.

Furthermore, inorganic fibers such as glass fibers, carbon fibers, and alumina fibers can also be used, and not only spinnable fibers but also non-spinnable fibers can be used effectively. When planting these fibers, each pile fiber can of course be planted as an independent piece with a free end, but it is also possible to plant all or part of the pile fiber in a loop shape. .

Furthermore, by mixing multiple types of pile fibers in advance and planting them, or by arranging multiple types of pile fibers with different materials, fineness, etc. in parallel, it is also possible to partially plant different fibers. can.

In addition, the base fabric on which the pile fibers are planted include woven fabrics, knitted fabrics, and laminates thereof, which are thread structures, nonwoven fabrics, nonwoven paper, and laminates thereof, which are aggregates of fibers, and A laminate made by combining the above-mentioned woven fabrics, knitted fabrics, non-woven fabrics, etc. can be used.

When pile fibers are arranged on the surface of the base fabric and a high-pressure fluid is jetted against them, the jet of the high-pressure fluid is generally 0.01 to The fluid is ejected at high speed from a nozzle with an inner diameter of about 1 mm, and various conditions are selected mainly depending on the properties of the pile fibers to be flocked.In other words, the fluid itself acts on the pile fibers, and its action is It is necessary to use force to entangle the pile fibers with the threads or fibers that make up the base fabric. Therefore, if the diameter of the pile #ara is too large compared to the diameter of the pile #ara, the intended purpose cannot be achieved; If it is too small, the desired acting force cannot be obtained.

The jet from the nozzle may be ejected intermittently or continuously, and it is generally suitable to use a liquid such as water as the ejected fluid. A mist containing the liquid in the form of water is also effective. Furthermore, in the case of materials for which a sufficient sutured state can be obtained even with a weak jet, the action of air flow is also effective.

When the jet stream is injected onto the pile fibers on the base fabric,
The thin jet of high-pressure fluid effectively entangles the pile fibers with the threads or fibers in the base fabric, and this tendency is reversed when the base fabric is placed on a metal support plate. The action of the jet stream also becomes noticeable when the pile fibers are entangled with the base fabric.

In order to continuously and sequentially flock fibers onto the base fabric according to the present invention, first, the ends of the pile fibers unwound from the pobbin are held on the base fabric, and the fibers are A portion of the fibers is entangled with the base fabric, and then pushed by a fiber operating rod that engages with this fiber, so that the fiber row with one end planted earlier is set to the adjacent fiber row planting position for the next pile. While tilting the nozzle to the opposite side, the fiber portion to be implanted next is led out onto the above-mentioned implantation position, and the flocking by the jet action described above is repeated.In this case, a two-dimensional moving device moves the nozzle to a predetermined position. Of course, it can be moved to the hair transplantation position.

By such a flocking operation, fibers of arbitrary length can be planted continuously at high density.

[Example] Examples of the method and apparatus of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the manufacturing apparatus of the present invention.

In this device, there is a base plate 10 on which the base fabric 1 is placed, and a pile river edge unrolled from the pobbin 2 on the surface of the base plate 10!
A high-pressure fluid on the order of 100 kg/crn or more is applied to the fiber guide means 11 consisting of guide rollers 12 to 14 for guiding the fibers 13 and the pile fibers 3a placed on the base fabric on the base plate 10. The nozzle 15 has a small diameter of about 0.01 to 1 intestine layer, and the nozzle 15 is relatively moved along the base fabric surface in a direction intersecting the pile fibers 3a, and the next flocking is carried out. a two-dimensional moving device 18 that moves the nozzle relatively also in a direction intersecting thereto, and a fiber operating rod 17 that engages with and pushes the fiber row led out on the base plate 1o. It is equipped with

When the pile river edge $13a is planted by the jet from the nozzle 15, the fiber operation rod 17 is used to control the fiber J13a.
By engaging with and pushing it, the planted fiber row is tilted to the side opposite to the next pile fiber row planting position adjacent thereto, and the fiber portion to be planted next is moved to the planting position. This is what we derive.

In the figure, reference numeral 18 is a piston type high pressure generator, from which water from the water storage tank 1B is ejected at high pressure in a pulsating flow state.

The base plate 1O is usually made of a metal plate, but a plate with many grooves or a perforated plate can also be used to discharge the injected fluid. This base plate 1G is designed to prevent damage to the base fabric by supporting the base fabric even if high-pressure fluid is injected onto the base fabric, and to provide a strong entangled state to the pile fibers by reflecting the jet stream. It is functional.

Next, the above structure and its operation will be explained in more detail with reference to FIGS. 2A to 2H.

As shown in FIG. 2A, the pile edge m3 unwound from the pobbin 2 is guided onto the base fabric 1 through the guide rollers 12 to 14, but at the start of flocking, its tip is properly fixed by the fixing means 21. It is fixed to the base fabric 1 or the base plate 10, and in this state, the nozzle 15 is lowered as shown in FIG. .

It is desirable that the pile fibers have as wide a width as possible in the direction perpendicular to the plane of the paper in FIG. 22 (see FIG. 1), the pile fiber is moved in a direction perpendicular to the plane of the paper by the width of the pile fiber.

After the pile fibers 3a are planted on the base fabric 1 as shown in FIG. 2C, the fiber operating rod 17 is moved from the position shown in FIG. 2C to the position shown in the same figure. That is, this fiber operation rod 17
engages with the pile fiber 3a as shown in the figure, and the second
As shown in the figure, the planted fiber row is tilted to the side opposite to the next fiber row planting position adjacent thereto, and the fiber portion 3b to be planted next is led out from the pobbin 2 accordingly. During this time, the base plate 10 is moved by the base plate moving device i24, and the next planting position on the base fabric 1 is positioned below the nozzle 15.

In this state, pile fibers are flocked onto the base fabric using the same jet flow from the glue 15 as shown in FIGS. 2B and 2C (FIG. 2E), and this process is repeated thereafter.

In this case, the fiber operation rod 17 is moved through an appropriate route as shown in FIG.
, C, and wait for the next operation.

If each of the planted fibers is to have a free end, the pile fibers may be cut at the fiber handling rod 17 in FIG. 2E.

Note that the above-mentioned hair-planting operation can be easily realized by synchronously driving each part of the hair-planting device.

As shown in FIG. 1, the two-dimensional moving device 16 that moves the nozzle 15 relative to the base fabric l for flocking includes a moving device 22 that moves the nozzle 15 in a direction perpendicular to the plane of the drawing. , it is preferable to configure the base plate 10 with a moving device 24 that moves the base plate 1O in a direction perpendicular to the direction of movement by the moving device 22.

It is also possible to adopt a configuration in which the nozzle 15 or the base plate 10 itself is moved two-dimensionally.

[Effects of the Invention] According to the method and apparatus of the present invention detailed above, various fibers can be used as pile fibers regardless of whether or not they are spinnable. It is possible to perform high-density and efficient hair transplantation.
