有している。Flat yarn cloth woven from conventional flat yarns of thermoplastic resin is currently used as the main fabric for carpets, but free movement of warp and weft threads, commonly called misalignment, occurs. It has the disadvantage that its strength decreases due to the enlargement of the gaps between the weaves and the spread of the damage to other parts, and the disadvantage that the edges easily fray when cut.

。Therefore, as shown in Fig. 14, a flat yarn cloth a is passed between a rotating steel roll b heated by an electric heater and an embossing roll C with a welding pattern formed on the surface to perform heat-sealing embossing. In recent years, a method has been adopted in which the intersections of the warp and weft of a flat yarn cloth a are heat-sealed to restrict movement of the warp and weft. However, even with heat fusion embossing, the fusion strength is relatively low and sufficient prevention of misalignment cannot be achieved.Moreover, in order to keep the pressure conditions constant for pressing the workpiece with both rolls, the workpiece must be There are drawbacks such as requiring thickness accuracy for the object and slow processing speed, and furthermore, depending on the temperature conditions, there is a problem that the molten part of the object to be processed may adhere to the roll. In addition, since the thermoplastic resin is heat-treated using a bulk heat source, heat denaturation occurs in parts of the material other than the fused parts, resulting in heat shrinkage, decreased flexibility, and decreased tensile strength of the entire processed material. A new problem arose, and furthermore, it was difficult to fuse different materials with different melting temperatures.

ずれ防止方法を６′ｆ１立した。In order to solve the above-mentioned problems, the present invention has developed a flat yarn cloth made of thermoplastic resin flat yarns by applying lip pressure in the direction of a rotating roll having a protruding fusion pattern on its surface and one pocket roll. We developed a method for preventing misalignment of flat yarn cloth by feeding it between placed cones for transmitting ultrasonic waves, ultrasonically fusing the intersection of the warp and weft, and regulating the movement of the warp and weft. .

するのである。The method for preventing misalignment of flat yarn cloth according to the present invention, which has the above-mentioned content, involves passing a flat yarn cloth made of thermoplastic resin flat yarn between a rotating roll and a cone for transmitting ultrasonic waves. The flat yarn cloth is brought into pressure contact with the fused pattern protruding from the surface of the drum and the cone pressed in the direction of the drum, and ultrasonic waves transmitted from the cone and focused only on the area corresponding to the fused pattern The intersection of the warp of the flat yarn cloth and the cotton yarn is fused, that is, the fusion pattern formed on the surface of the rotating I-cool is transferred to the surface of the flat yarn cloth I and ultrasonically fused, and the warp and the cotton yarn are This regulates the movement of the weft threads.

がりを防止したものである。In addition, the flat yarn cloth manufactured by the above method is obtained by stochastically ultrasonically welding the intersections of the warp and weft using a fusion pattern that is uniformly distributed on a plane, and the intersections are fused together. This restricts the movement of the warp and weft threads, thereby preventing misalignment, fraying at the cut end, and the spread of damage to other areas.

る。Normally, flat yarn cloth is made by weaving polyolefin flat yarns such as polypropylene and polyethylene into the warp and weft, and is widely used as carpet base fabric, flexible containers, grain bags, sandbags, soil improvement materials, etc. It's being used. In addition, flat yarn cloths made of polyester, nylon, etc., and flat yarn cloths made by blending polyolefin flat yarns with polyester, nylon, etc. flat yarns are being widely used as agricultural and industrial materials in addition to the above-mentioned uses.

明はその打込み本数には制限されるものではない。The method of the present invention uses ultrasonic waves to fuse the intersections of warp and weft yarns, that is, the web intersections of the cross web, to prevent a decrease in flexibility due to the high strength of ultrasonic fusion and partial heating of only the fused areas. While having these excellent features, it is also able to prevent misalignment, and this effect is particularly noticeable in cross webs with a small number of warp and weft yarns, such as flat yarn cloth with less than 8 threads per inch, i.e. 8x8 or less. However, the present invention is not limited to the number of implants.

前記交差部１２に対応する。FIG. 1 is a simplified diagram of an apparatus for ultrasonically welding flat yarn cloth 1 according to the present invention, in which the flat yarn cloth 1 unwound from one unwinding drum 2 is fixedly attached to the other winding drum 3. A plurality of rollers are wound at a speed and arranged in the middle.4. . . . The flat yarn cloth 1 is guided between a rotating roll 5 whose surface has a protruding fusion pattern P and a cone 6 for transmitting ultrasonic waves. Here, the cone 6 is connected to a normal ultrasonic generator (not shown), and the ultrasonic transmitting device 8 at the tip is pressed in the direction of the rotating roll 5 by a presser Pi7 that can adjust the pressure g. death,
The flat yarn cloth 1 is fed between the converging section 8 and the rotating roll 5. Then, as the ultrasonic waves are concentrated at the part where the distance between the protrusion 9 and the cone 6 that forms the fusion pattern p is narrowed, the warp 10 and weft 1 of the flat yarn cloth 1 are separated as shown in FIG. The intersection 12 is ultrasonically fused. In this way, a large number of the fused patterns p are uniformly distributed over the entire surface of the flat yarn cloth 1.
The cross section 12 of the warp yarn 10 and the weft yarn 11 is essentially fused. Note that this fused portion 13 is
This is indicated by a black dot in FIG. 2, and the fused portion 13 corresponds to the intersection 12 according to probability.

に引張強度が低（なることが判る。From the above tensile strength test results, the →1 tensile strength in the longitudinal direction of the flat yarn cloth l treated with ultrasonic fusion treatment is approximately Roll contact pressure from 80% to 2, 'l kg
/ ctn, and that in the transverse direction also decreases from about 64% to about 57%, but the tensile strength in the diagonal direction remains approximately constant even when the roll contact pressure is changed within the above range. It was found that the increase was approximately 1.5 times. On the other hand, the longitudinal tensile strength of heat-sealed flat yarn cloth a is approximately 84 when the roll nip pressure is 15 kg/c1n.
%, the roll nip pressure decreases from 40% to about 56% of that in the 40' case, and that in the transverse direction also decreases from about 60% to about 53%, and the tensile strength in the diagonal direction changes the roll nip pressure in the above range. The tensile strength is almost constant and is the same as that of the untreated one, and in addition, the heat fusion treated one has a larger change depending on pressure conditions than the ultrasonic fusion treated one, and the tensile strength is lower overall. .

してフラットヤーンクロスｌの各方向に対する引張強度
が接近する傾向を示し、全体的に強度の向上が図れる。That is, with ultrasonic fusion treatment, the change in tensile strength is more gradual with respect to the change in pressure conditions caused by the pressing means 7, so it is easier to set the conditions, and the thickness of the flat yarn cloth 1 changes. It was found that there was little variation in quality even when the contact pressure changed, and what is more distinctive is that the tensile strength in the diagonal direction is significantly superior, and the tensile strength in each direction of the flat yarn cloth l tend to approach each other, and overall strength can be improved.

1.3% for +a to 3. for 40kg/cm.
It can also be made into 7 pieces. Furthermore, when measuring the elongation, which objectively indicates the good feel, the heat-sealed material showed a lower value than the ultrasonic-sealed material, indicating that it was clearly harder.

込み本数が少ないためである。Note that the reason why the tensile strength in the transverse direction is inferior to that in the longitudinal direction is because the number of implants is small.

In order not to reduce the tensile strength and flexibility of the fused portion 13, it is necessary to optimally set the ratio of the area of the fused portion 13 per unit area, the area of each fused portion 13, and the density distribution. Therefore, the area per 13 fused portions of the fused pattern p can be set to 0.001 to 5 mm2, but in this embodiment it is set to 0°01 to 3+u2. Further, the ratio of the area of the fused portion 13 per unit area of the flat yarn cloth 1 can be set in the range of 0.5 to 75%, but in this example, it is set to 1 to 70%. There is. If the area of the fused portion 13 is less than 0.001 am'', it is difficult to process the protrusions 9 of the rotating drum 5 that form the fused pattern p, and maintenance and handling of the rotating drum 5 is difficult. Although the welding of the intersection 12 of the warp 10 and weft 11 of the flat yarn cloth l is done reliably with 5 dragons 2 and above, it may lead to a decrease in physical properties, that is, heat shrinkage and a decrease in tensile strength. In addition, if the ratio of the area of the fused part 13 per unit area is 0.5% or less, the area where the fused part 13 is formed at the intersection 12 becomes small, and the warp 10 and weft 11 The movement cannot be controlled, and if it exceeds 75%, the strength and dimensional stability, which are the characteristics of the flat yarn 1, are lost as described above.

However, it is preferable that the area ratio is as small as possible, and examples thereof are shown in FIGS. 5 to 13.

Figure 12 shows one in which ring-shaped fused parts 13 are arranged in a diagonal lattice pattern in a set of four crosses. FIG. 13 shows solid round fused portions 13 arranged densely in a grid pattern. As described above, the shape of the fused portion 13 may be circular, oval, rectangular, square, diamond, ring, horseshoe, cross, etc. as shown in the figure, and various shapes may be adopted for the distribution thereof. .

It is possible to perform ultrasonic fusing treatment to suppress the tension, maximize the tensile strength in the diagonal direction, prevent misalignment of the warp threads 10 and the weft threads 11, and provide flexibility.

A flat yarn cloth made of flat yarns of thermoplastic resin is fed between a rotating roll with a fused pattern protruding on its surface and a cone for transmitting ultrasonic waves placed close to each other while being pressed in the direction of the roll. The intersection of the weft and warp yarns is ultrasonically fused to regulate the warp and weft transition J, which reliably prevents misalignment of the flat yarn cloth and fraying at the cut edge, and improves the tensile strength in the diagonal direction. It is possible to increase the tensile strength of the flat yarn cloth by about 1.5 times compared to that of untreated and heat-sealed cloth, making it possible to make the tensile strength of the flat yarn cloth close to isotropic, so that tensile stress does not act from any direction. Even if the damage occurs, the strength is increased, the risk of damage is reduced, and the damage can be prevented from spreading by 4° beyond the damaged area. In addition, when conventional heat fusion treatment is applied, heat shrinkage occurs by about 1.3 to 3.7% depending on processing conditions, but the present invention's method of applying ultrasonic fusion treatment to the intersection of the warp and weft of the flat yarn cloth And the treated flat yarn cloth has almost no shrinkage before and after the treatment, and the flat yarn cloth as a whole does not undergo thermal denaturation.
There is almost no loss of flexibility and the soft touch of the untreated product can be maintained.
