Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sheet material with a leather-like lace pattern used for various articles such as footwear and bags, and a method for producing the same.

[Conventional technology]

Lace, especially handmade lace, is said to be the highest form of art that human beings can create.Originally, lace is a fabric with decorative patterns on a transparent background woven by twisting, knitting, or combining threads. Lace refers to a type of lace that usually has a pattern created by a combination of netting and shibori, but is also commonly referred to as lace, including embroidered lace, which is created by applying embroidery to fabric to create an openwork pattern.

[Problem to be solved by the invention]

Lace fabric has traditionally been used exclusively for curtains, tablecloths, etc. due to its texture.

The detailed see-through pattern of lace is excellent as a design, and various attempts have been made to utilize the detailed pattern of lace as a design for articles. A typical example is the method of printing or embossing the surface of synthetic leather to create a lace-like pattern. According to this method, a lace-like pattern can be displayed on the surface of various leather products such as bags, cases, and belts.

However, when printing or embossing synthetic leather, no matter how precisely the shape of the lace pattern is expressed, it cannot come close to the texture and feel of fabric due to the difference in materials.

On the other hand, laces coated with resin and reinforced with PvC processing are known, but these methods focus only on retaining flexibility, and their texture is inferior, and their uses include tablecloths, etc. was limited to.

The purpose of the present invention is to improve not only the shape and pattern of lace, but also to
To provide a sheet-like article with a leather-like lace pattern, which can be expressed as a design of various articles including texture and touch, and a method for producing the same.

[Means for resolving division issues]

In the sheet material with a leather-like lace pattern of the present invention, a base material such as woven fabric, non-woven fabric, or PVC leather, a lace cloth having a see-through pattern adhered to the surface of the base material, and a shape and pattern imitating the original fabric. It has a transparent polyurethane resin coating layer covering its surface.

In addition, in the method for producing a sheet material with a leather-like lace pattern of the present invention, a urethane adhesive is applied on a release paper,
Next, there is a first step of pasting a base material such as woven fabric, non-woven fabric, PVC leather, etc. on the adhesive-coated surface, and a release paper is removed from the m-layer body in the first step to form a base material on the surface of the base material. A second step of overlaying the lace cloth on the adhesive-applied surface, and a third step of applying a urethane-based transparent adhesive to release paper and overlaying the lace cloth of the laminate from the second step on the applied surface. and the third
and a fourth step of thermo-pressure welding the laminate obtained in the step.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, the sheet-like article with leather-like lace g of the present invention includes a base layer 1, a lace cloth 2 attached to the surface of the base layer 1, and a transparent coat layer 3 covering the surface. It consists of laminated layers. Specifically, an adhesive layer 4 is formed on the surface of the base layer 1, and the lace cloth 2 is adhered to this adhesive layer 4. The same transparent resin as the coat layer 3 can be used for the adhesive layer 4. The procedure for laminating the synthetic resin coat layer 3 on the base material layer 1 and processing it into a sheet-like product is substantially the same as the general synthetic leather manufacturing process. By selecting the material of the base layer 1, the conditions for the synthetic leather, such as flexibility, hardness, mechanical strength, etc., can be freely set.

The base material layer 1 may be made of knitted fabrics, woven fabrics, nonwoven fabrics, chlorinated leather, nil leather, or other materials used for synthetic leather base materials, regardless of wet or dry methods.

When the fabric of the lace cloth 2 is white, it is desirable to use a dark-colored base layer in order to clearly show the see-through pattern of the lace cloth 2. However, the surface of the base layer 1 may be colored or patterned with any color. can be formed.

The type of lace cloth 2 is not particularly limited, and includes 0 handmade lace, 9 machine lace (fabric lace, thread lace) as well as lace-like patterns made from knitted structures. However, the C and F (cover factors) are preferably 80 or less; if they exceed 80, there is a risk of delamination. A transparent two-component polyurethane resin paint is preferable for the adhesive that adheres the lace cloth 2 to the base material layer 1 and the coating layer 3 that covers the surface of the lace cloth 2. The two-component polyurethane resin paint has chemical resistance and resistance. Excellent abrasion and adhesion properties.

The paint of the coating layer 3 covering the surface of the lace cloth 2 adhered to the base material layer 1 impregnates the structure of the lace cloth, and the adhesive layer 4
The lace cloth 2 is embedded in the coat layer 3, and the surface of the coat layer 3 is formed with unevenness in the shape of the three-dimensional pattern of the lace cloth 2.

Note that the lace cloth 2 can be colored in any color by using a colored paint in the coating layer 3.

The manufacturing process of the leather-like lace-patterned sheet material of the present invention is shown below.

In FIG. 2(a), a two-component polyurethane resin paint (adhesive) 12 is applied to the upper surface of the first release paper 11 while being continuously fed, a base material 13 is placed on the paint-coated surface, and a roll 14 is applied to the first release paper 11. They are pressed together and the laminate 15 is wound onto a first roll 16. In FIG. 2(b), the first release paper 11 is removed from the laminate 15 pulled out from the first roll 16, the lace cloth 17 is placed on the exposed surface coated with the paint 12, and the roll 1
8 and winds up the laminate 19 onto a second roll 20.

In FIG. 2(C), a two-component polyurethane resin paint (coat layer) 22 is applied to the upper surface of the second release paper 21 while being continuously fed, and the laminate 19 is pulled out from the second roll 20. The surface of the lace cloth 17 is overlapped with the coated surface, and the laminate 22 is rolled up onto a third roll 23 by pressing against it with a roll 26.

In FIG. 2(d), the laminate 22 pulled out from the third roll 23 is thermocompressed between the hot rolls 24 and 25 of an embossing machine to obtain a sheet material with a leather-like lace pattern shown in FIG. Note that the second release paper 21 is peeled off before or after the thermocompression bonding process using an embossing machine.

〔Effect of the invention〕

As described above, according to the present invention, the detailed patterns and uneven shapes of the lace cloth can be expressed on the surface, and since the lace cloth is covered with a polyurethane resin coating layer, it does not get dirty and can be formed into a predetermined shape with a soft feel. It is possible to obtain a synthetic leather-like sheet-like article that retains its shape and takes advantage of the texture and feel of lace cloth.

The sheet-like material of the present invention is similar to general synthetic leather, and is used for covering 9 skins of footwear such as shoes, sandals, and slippers, for bags, and for bags.
When used for cases, belts, and clothing materials, it has the effect of expressing the appearance of the lace cloth as a surface design of the article without impairing its texture.
