Fabric for automobile seats using liquid adhesive for processing automobile seats

For the purpose of providing a method of combining, and more specifically referring to the accompanying drawings 1 and 2, the method of combining the fabric for a car seat using the liquid adhesive of the present invention is based on one surface of the base fabric 30 or one surface of the foam member. The liquid adhesive 50 is coated using a pattern roller 60 or a pattern mask coating device 300.

At this time, the liquid adhesive 50 melts the thermoplastic adhesive in the form of particles into a liquid in the melting device 50 and supplies it to the pattern roller 60 at room temperature through an ejector.

The supplied liquid adhesive 50 is inserted into the pattern groove 62 formed by being engraved in the pattern roller 60 to be positioned, rotated according to the feed speed of the base fabric 30 or the pain member, and the pattern roller ( 60) while the coating roller 80 is positioned on the other side, and the base fabric or the pain member passes through the coating roller 80 and the pattern roller 60,

The liquid adhesive 50 is coated to have a certain pattern on the top surface of the base material fabric 30.

[32] Although not shown in the drawings, a raw material is supplied between the fixed roller 70 and the patterned roller 60, and the knife attached to the fixed roller 70 scrapes the surface of the coating roller 60 to coat the coated roller 60 ) In the intaglio portion only enters the liquid adhesive (50)

A structure in which the surface of the coating roller 60 is arranged in such a way that the liquid adhesive 50 is also applied to the foam member can also be used.

[33] Preferably, the pattern roller 60 is preferably heated to a predetermined temperature in order to prevent the provided liquid adhesive 50 from being hardened. As shown in FIG. 2, as shown in FIG. The first vertical adhesive with a pattern of adhesive applied by the roller having a certain length and width and a coating thickness in the longitudinal direction of the roller

The coating line (12) and the first horizontal adhesive coating line (14) are repeated and arranged regularly, and the first horizontal adhesive coating line (14) is coated and formed to be positioned at the center of the first vertical adhesive coating line (12). The first coating line (10), the second horizontal adhesive coating line (22) and the first horizontal adhesive coating line (14), which are coated so as to be positioned in the center direction below the first vertical adhesive coating line (12), and the first horizontal adhesive coating line (14) 2) The second vertical adhesive agent forming line (24), which is formed by being applied to the lower side, is repeated and arranged regularly, but the second horizontal adhesive agent forming line (22) is coated so as to be located at the center of the second vertical adhesive agent forming line (24). The second coating line 20 formed by forming is formed, and the

There is a technical feature in that the pattern of the coating form of the liquid adhesive is formed so that the first application line 10 and the second application line 20 are alternately crossed and formed repeatedly in the longitudinal direction of the foam member or the fabric.

[34] In this way, the liquid adhesive 50 is applied to form the adhesive layer pattern,

By supplying the leather fabric 40 or foam member, it passes through the pressing rollers 42 and 14 to be combined. At this time, it is recommended that the pressing roller use a heating roller that maintains a predetermined temperature, so that the fabric is well-formed.

Guided by the guide roller (92), it is completed by winding it with a winding roller (94).

[3 到 Unexplained drawing number 70 is a fixed roller and is attached to the pattern roller (60). 2020/091175 1 »(： 1 ^ ¾2019 / 007146 Liquid adhesive (50) to be fixed, to form a certain partial step (72)

The cutting portion 74 has a formed shape. At this time, the fixed roller is in a fixed state without rotating, and the stepped portion 72 of the fixed roller is rotated to the pattern roller 60 while the pattern roller 60 rotates. It induces the liquid adhesive to be evenly drawn into the formed engraved pattern, and also on the surface other than the engraved pattern of the pattern roller 60.

The liquid adhesive 50 performs a function of not remaining.

[36] According to the present invention, preferably, as shown in 2, the first horizontal adhesive coating line 14 and the second horizontal adhesive coating line 22 have one end (\, w2) at the time of forming the coating layer. It is desirable to be coated so that they overlap so that if they come off without overlapping, the uncoated portion of the adhesive forms a certain line and is relatively weak compared to the applied portion when the load is applied. There is a problem that wrinkles are formed in the part. In addition, in the case of natural leather that is sensitive to heat / humidity, the leather contracts and relaxes according to the main transducer without applying a load. It can deteriorate the leather deformation. More preferably, the overlapping portion (0) at the one end is preferably applied to satisfy the range of 0.1 to 3111111.

[37] According to the present invention, the application line task 1 horizontal adhesive application line is 1 ~ 10_

And 10 ~ 100 炯

It is formed to have a coating thickness ((13).

[38] If the above adhesive line is less than 1, the pattern itself is small.

There is no difference in frontal coating in terms of emotional quality, and when it exceeds 10111111, there is a disadvantage in that the number of non-coated areas on the leather piece adhesive for seats increases, which may cause peeling during sewing.

[39] In addition, when the width is less than 0.1_, there is a disadvantage that the peeling strength is weak because the desired coating thickness does not appear, and when it exceeds 1_, the adhesive layer of the adhesive layer under the repeated weighting situation is outside the leather. The disadvantage is that it can be seen as a robo.

[40] In addition, the coating thickness of the adhesive varies depending on the material to be adhered, and there is a disadvantage that the peel strength is significantly lower when it is less than 10 or 111, and 80 yo 1½88 of natural leather when exceeding 100 or III. The disadvantage is that emotional quality such as lecture intensity and ventilation performance are significantly lowered and the curing time is longer, which can lead to problems caused by uncured in an emergency response.

[41] According to the present invention, preferably, the application of the adhesive is from 5 to 50 per inch.

It is desirable to be coated to have a coating density, or to apply the adhesive with a coating ratio of 23 to 35% compared to the area of the fabric or the area where the adhesive is applied. If the coating density or the coating ratio is outside the threshold, the peel strength is peeled off. Uh)

There may be problems with worsening or 8 ₀ ^ ₈₈ 71- worsening.

[42] 2020/091175 1 »（： 1/10 公 019/007146

[43] According to the present invention, the application pattern of the adhesive is any of the patterns shown below.

It can be formed by applying a single pattern. (See Figure 3)

ápattern 1> ápattern 2> ápattern 3> ápattern 4> <pattern 5>

[4 到 The patterns 1, 2, 3 to 5 are designed according to the blade direction of the coating machine.

The coating amount can be changed so as not to change the coating amount, and the pattern 3 is a pattern in which projections are added to improve the peel strength of pattern 1, and the adhesive line can have projections at both ends, and the projections can be applied to the first horizontal distribution line. When formed, its size

It is preferable that it is not larger than the first vertical application line, and when the projection is formed on the first vertical application line, it is preferable to be formed smaller than the second horizontal application line at the bottom. More preferably, the projection is 1/3 the length of the application line. It is better to be formed to have the following length, and its width and thickness are preferably formed to be the same as the above-mentioned coating line. In addition, as shown in Pattern 5, the 11 vertical adhesive line and the 1 horizontal adhesive line are two or more lines. It can have an aggregated shape and this set shape can be seen as an application line.

[46] Meanwhile, for the convenience of the present invention, the forms of the first horizontal adhesive system and the first vertical adhesive system are explained based on the letters I and 1, but one of the letters and symbols such as I, I, 丄,, +, or Two or more can be used in a mixed arrangement.

[4 刀 According to the present invention, as shown in FIG. 4, the pattern mask coating device 300 is a cylindrical screen pattern coating plate 250 and a device installed on the inside of the cylindrical screen pattern coating plate 250 Adhesive injection device head (100) equipped with an adhesive inlet port (110) for supplying a low-liquid adhesive; and an adhesive injection port (130) configured to be integrally coupled to the adhesive injection device head and spraying ink; and of the adhesive injection port It is configured on one side or both sides, and then sprayed by the adhesive injection port.

Adhesive recovery means 120 for recovering the adhesive remaining on the cylindrical screen pattern coating plate 250; It is located on the upper side of the adhesive injection device head, the

Includes; a cleaning roller 220 that is tightly installed on the outer surface of the cylindrical screen pattern coating plate 250;

[48] The pattern mask coating device 300 and the pressure cylinder 260 are in close contact with the fabric 160 to be coated and transferred simultaneously, and the liquid adhesive is formed of a foam member or fabric by the pattern mask coating device 300. It is also spread on one side to form a pattern. The head portion 150 is integrally formed on the adhesive recovery means 120,

The adhesive coating head device 270 is composed of an adhesive injection device head 100 and a head portion 150 on the adhesive recovery means 120. [49] Using the method of forming the adhesive fabric pattern according to the present invention as described above, prepare a spun support group used for automobile seat processing as a base material, and pass the spun support group through the pattern roller 60 in FIG. In the form of (Pattern 1), an adhesive coating pattern was formed, and a synthetic fabric with leather was fabricated. The prepared fabric fabric was prepared with 5 samples. At this time, the coating thickness was 50 / zra, the coating bar rate was 13.5%, A total of four samples were prepared at a ratio of 18.5%, 23.5%, and 30.5%.

Softness was measured and measured.

[5 is also another embodiment according to the present invention, as shown in FIG.

The pattern mask coating device 300 is used to form the adhesive pattern coating pattern, and the subsequent process is to apply the fabric to the same conditions as the method using the pattern roller.

Five samples were prepared for the fabricated fabric. At this time, the coating strength was 50 ^ m, the coating ratio was 13.5%, 18.5%, 23.5%, and 30.5%. Measure and see the softness.

[51] The appearance, physical properties, etc., of the prepared two fabric fabrics were tested, and as a result, the product characteristics as shown in Table 1 were shown. The test results were tested after each of five samples in each case. Values are averaged.

[52] Among the samples used in the tests in Tables 1 to 4, the non-ventilated leather specifications (softness 2.0-2.1) and the foam were all the same with 34kg 10T (Olefin coating).

[53] [Table 1]

[54] As a result of Table 1, it was found that the most desirable properties were obtained when the coating thickness was 50 // 111 / the coating ratio was 23.5%, or 30.5%. In particular, the coating thickness was 50 쌘! / At the application rate of 23.5%, it was found that the optimum quality was obtained. At this time, 50 yo 1 ^ 8

It was found that the increase was about 0.3. On the other hand, when the application rate is 18.5% and 13.5%, the softness is improved, but the peel strength is noticeably decreased. The liquid adhesive was applied to the entire area according to the conventional method. Prepare the fabric fabric applying the method of applying (see Table 2) and the fabric fabric applying the method of applying the dot-type adhesive system according to the method of Patent No. 10-0419240 (Tables 3 and 4) to prepare the fabric fabric of the present invention. It was tested in the same way as the physical property test method, and the results are shown in Tables 2 to 4. [55] [Table 2]

[56] The test sample in Table 1 was prepared with leather non-ventilated specification / foam 341¾ 101 olefin.

As can be seen from Table 1 above, as a result of the peel strength test when the entire surface of the liquid adhesive was applied, it was found that the amount of coating caused by the sponge fracture occurred at 4 / or more. The deviation of the roll-to-roll type equipment was about 1.5 and about 1¾ /, so the optimal coating amount was set to 50, and the specific gravity of the raw materials used was about 1.06, and the conversion thickness was about 47_ /.

[57] It was found that the sponge fracture occurred at a coating thickness of 50 (approximately 5 均 /) or more.

[58] [Table 3]
