Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a patterned synthetic leather in which the lower fabric of a textile product is coated with an upper fabric made of a thermoplastic synthetic resin such as polyurethane or vinyl chloride. More specifically, the swelling of the handle is larger than that of the conventional patterned synthetic leather. It relates to a certain patterned synthetic leather.

[0002]

[Prior art]

 Conventional patterned leather is used for furniture chairs and seat surfaces of seats for cars, etc. However, since leather on the surface alone is easily torn, from the point of maintaining strength, it is patterned leather. A flat, flat textile product (such as a knitted fabric) of a predetermined thickness is used under the flexible thin patterned sheet of thermoplastic synthetic resin such as vinyl. Since the pattern is formed on the surface of the thermoplastic synthetic resin sheet as the upper cloth, as shown in the cross-sectional view of the conventional patterned synthetic leather 3A in FIG. A predetermined pattern is formed in the recess (groove) 4A, and the upper fabric 2A with the pattern is adhered to the upper surface of the flat lower fabric 1A having a predetermined thickness, which is thicker than the upper fabric, with an adhesive. To form patterned synthetic leather.

[0003]

[Problems to be solved by the invention]

 The conventional patterned synthetic leather pattern is formed by pressing the synthetic resin sheet surface of the flat upper cloth 2A covering the upper surface of the flat lower cloth 1A of a predetermined thickness by pressing. Due to the restrictions, it was not possible to give a bulge even though a pattern could be formed on the upper surface of the upper fabric. The present invention has been made in consideration of this point, and provides an interesting synthetic leather with a pattern that has an unprecedented swelling pattern on the upper fabric forming the synthetic leather surface. It is intended to be.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the patterned synthetic leather of the present invention is a small number of patterned synthetic leathers in which the lower fabric of a textile product is covered with an upper fabric made of a thermoplastic synthetic resin such as polyurethane or vinyl chloride. The upper and lower fabrics are formed with a textured pattern on the upper surface of the lower fabric, and a thin flexible upper fabric that is not pre-patched is coated on the upper surface of the lower fabric, and the lower fabric is covered and adhered so that the textured pattern of the lower fabric rises on the upper surface of the upper fabric. It is formed so that the pattern of the fabric is made of synthetic leather. As a result, unlike the conventional patterned synthetic leather with a flat upper fabric in which a pattern is formed by a groove due to pressing, the uneven fabric of the lower fabric is raised on the upper fabric upper surface and swells. Therefore, it is possible to obtain a patterned synthetic leather which is rich in interest.

In this case, as described above, a flexible and flat thin sheet made of a thermoplastic synthetic resin such as polyurethane or vinyl chloride is used as described above. On the other hand, as the lower fabric, the following various fabrics can be used as a fabric having a pattern in an uneven state on at least the upper surface.ニ Knitted quilted fabric for knitting by creating a place where the front and back faces are doubled and a place where it is not the same, to create unevenness.タ Tack knitted fabric by knitting method that gives unevenness by tack.編 み Knitting and weaving fabric that creates unevenness due to the difference in yarn thickness.編 み A knitted or woven fabric that has been subjected to knitting or weaving using a shrinking yarn or an elastic yarn to give an uneven pattern.編 A knitted fabric with an uneven pattern depending on the pile height or the presence or absence.編 Knitted fabrics that create unevenness using the front and back stitches (links stitches, transfer stitches, etc.).生地 Fabrics such as quilts, embroidery, etc., which are made by sewing with irregularities and sewn with other fabrics.

When a synthetic leather with a pattern is formed by bonding an upper fabric and a lower fabric, a polyurethane-based adhesive, a vinyl chloride-based, or a polyester-based adhesive is used as a binder depending on the fabric.

In order to coat the upper fabric with the upper fabric, the upper fabric is preferably elastically pressed and adhered to the upper surface of the lower fabric via the same type of adhesive as the material of the upper fabric. When using a metal roller according to the type of lamination or pattern, the thin, flexible upper fabric is slightly dissolved by the same type of adhesive as the upper fabric, and the back of the upper fabric is slightly dissolved and adapted to the uneven surface of the lower fabric. The convex surface of the fabric is adhered (while restoring a slight dent), and a patterned synthetic leather having an uneven surface is formed. In this case, it is desirable that the bulge due to the unevenness is not too large and the bulge can be felt.

Another means of coating the upper cloth on the upper surface of the lower cloth is to form a sheet of the molten thermoplastic synthetic resin (the thermoplastic synthetic resin is softened and melted by heat) as the upper cloth material. It can be applied to the upper surface of the fabric to make the upper fabric covered. As a result, the upper fabric can be satisfactorily covered and adhered to the upper surface of the lower fabric even if the upper fabric is slightly affected by the size of the unevenness of the lower fabric.

[Embodiment of the invention]

 Preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the patterned synthetic leather of the present invention, and FIG. 2 is a cross-sectional view showing the progress of manufacturing the patterned synthetic leather of FIG. As shown in FIG. 1, this synthetic leather 3 with a handle has an upper fabric 2 made of a thin flexible polyurethane sheet on the upper surface of a lower fabric 1 having a quilted pattern in an uneven state on the upper surface. The quilt-shaped pattern with irregularities is coated tightly so that it emerges.

The patterned synthetic leather 3 is quilted as a lower cloth 1 having an uneven pattern formed on the upper surface thereof by using synthetic fibers such that the lower surface is flat and the upper surface has a predetermined crossed seam. A knitted quilted fabric is used, and a thin polyurethane sheet colored in a predetermined color (for example, yellow) is used as the flat, thin, and flexible upper substrate 2 without a pattern. The upper fabric 2 is coated on the upper surface of the lower fabric 1 by applying a polyurethane-based adhesive to the lower surface of the flat upper fabric 2 as an intermediate binder (not shown in FIG. 2). Then, the upper fabric 2 is adhered to the lower fabric 1 by pressing with a rubber roller to produce a patterned synthetic leather 3. At this time, the upper fabric 2 is thin and flexible, and the lower surface is slightly melted and softened by the polyurethane-based adhesive and is elastically pressed by the rubber roller. It is possible to form a patterned synthetic leather that is familiar and adhered to the surface and has a bumpy surface.

As described above, the upper cloth 2 which is a polyurethane sheet is adhered to the lower cloth 1 having a quilted pattern via a polyurethane-based adhesive to cover the upper cloth, instead of using an adhesive. Alternatively, the upper fabric 2 may be coated by applying the melted polyurethane material of the upper fabric to the upper surface of the lower fabric 1 while forming a sheet. The lower surface of the liquefied polyurethane that is applied while forming this sheet is slightly penetrated between the fibers on the upper surface of the lower fabric, and is coated to form a patterned synthetic leather with a quilt-like uneven bulge on the surface. .

In the above-described embodiment, a knitted quilt knitted fabric having a quilt-like unevenness on the upper surface has been described as the lower fabric 1. A knitted fabric with a pattern, a knitted fabric of various fibers or a knitted or woven fabric with an uneven pattern formed on the upper surface or both upper and lower surfaces can be used as the lower fabric, while a vinyl chloride or the like is used as the upper fabric. It is also possible to use a thermoplastic synthetic resin, and various changes can be made without departing from the gist of the present invention.

[Effect of the invention]

 According to the patterned synthetic leather of the present invention as set forth in claim 1, a thin, flexible upper cloth that is not preliminarily patterned is provided on the upper surface of the lower cloth having an uneven pattern, and the pattern of the lower cloth is raised on the upper cloth upper surface. By making the lower fabric pattern a synthetic leather pattern by covering and contacting it, it is possible to obtain an interesting patterned synthetic leather having a swelling and uneven pattern that has never been seen before. .

According to the present invention, the upper cloth is elastically pressed and adhered to the upper surface of the lower cloth with a rubber roller or the like via an adhesive of the same system as the material of the upper cloth, so that the upper cloth can be easily formed. Can be blended with the pattern on the upper surface of the lower fabric to form a patterned synthetic leather.

According to the third aspect of the present invention, since the melted thermoplastic synthetic resin as the upper cloth material is applied and covered on the upper surface of the lower cloth while forming a sheet, the influence of the size of the unevenness of the lower cloth. The upper cloth can be covered and adhered to the upper surface of the lower cloth well even if it is slightly uneven without being affected.
