Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a leather-like yarn that is excellent in appearance, hand, strength, loop formation, bulkiness, and stability in two dimensions.

(Prior art) Conventionally, non-woven fabrics, natural leather, etc. were cut to produce clothing,
Widely used for bags, interior goods, etc. However, in the case of non-woven fabrics, the strength is weak when cut,
It is said that it is difficult to obtain beautiful loops when the tension or waist is small or when using a single knitted fabric.

There was a problem with the poems being easy to wear.

Natural leather also has major drawbacks in terms of handling, such as difficulty in obtaining long lengths, uneven quality, difficulty in washing, and difficulty in daily care.

Furthermore, 1) there is a strong demand for something that has a three-dimensional effect and 9 has a variety of colors.

(Object of the Invention) The present invention improves the drawbacks of the prior art and improves the appearance quality by improving the appearance quality.
The purpose of this invention is to obtain a novel leather-like yarn with excellent strength and handleability, and a woven or knitted fabric using the same.

(Structure of the Invention) The gist of the present invention is as described in the claims of the present application.

That is, the present invention relates to a leather-like yarn having a fibrous substrate having a silver surface on one side, and characterized in that the front and back sides of the yarn have different colors.

The fibrous substrate of the present invention is made by needle bunching fibers such as polyester, polyamide, polyacrylic, etc.

A fibrous sheet such as a watershed punched non-woven fabric or woven fabric, to which various commonly known high molecular weight polymers such as polyurethane or acrylic resin are applied, if necessary, and preferably colored.

When the surface of the fibrous substrate is made up of fine fibers and/or bundles thereof, it is preferable because its smoothness allows the grain layer to be made thinner, resulting in a soft texture.

Ultrafine fibers are obtained from sea-island type polymer mutual array fibers, peelable composite fibers, special polymer blend type fibers, etc., and the fineness is preferably 0.08 denier or less, and preferably 0.3 denier.
Less than denier.

In the case of non-woven fabrics made of ultra-fine fibers, we start with high-basis weight felt and then proceed to the final base sheet stage.

It can be sliced into at least 2 slices, or more preferably 4 to 6 slices, which is desirable as it increases production efficiency.

In addition, as a fibrous substrate, a woven or knitted fabric made of ultrafine fibers, a composite entangled body in which ultrafine fibers are entangled and sandwiched from both sides of a woven or knitted fabric of normal fineness fibers, or a mixed woven fabric of two normal edge fibers and one female knitted fabric with ultrafine fibers are used. However, if necessary, those coated with polyurethane, polyacrylic, etc. may also be used.

For example, it is preferable to use commonly used polymers such as polyurethane, polyvinyl chloride, and polyacrylic, to which pigments, dyes, stabilizers, and the like are added, if necessary.

The silver surface is formed by a commonly used method such as a dry method or a wet method such as a lamination method, a gravure method, a spray method, a roll coating method, or a knife coating method.

In the leather-like yarn of the present invention, such silvered artificial leather must be in the form of a yarn. As for the shape, the thickness is 0
．． It is preferable to have a width of about 5 to 1.0 m and a width of about 1 to 5 plates, but a desired one may be obtained depending on the purpose.

However, depending on the thickness and width of the base sheet, various shapes as shown in FIGS. 1 to 6 can be obtained, so it is sufficient to appropriately select and use them depending on the two uses. For example, if you want to emphasize the features of the silver surface, use the one in Figure 1, and if you want to emphasize the suede surface, use the second one.
You can use the one shown in the figure.

To make the artificial leather sheet into yarn, it is preferable to use a cutting machine.

Note that it is of course possible to apply force to the silver surface after forming the two artificial leather sheets into a yarn shape.

The leather-like yarn of the present invention must have different colors on the two sides.

The term "color difference" as used in the present invention refers to a comprehensive color sense such as hue, saturation, brightness, gloss, etc. that can be easily discerned with the naked eye, but is preferably measured using a spectrophotometer. ,
It is preferable that the difference in dominant wavelength is 10 mμ or more, or the difference in L value is 5 or more in color measurement using a color difference meter.

Here, the L value refers to the value based on J Engineering S Z-8730.

One possible way to impart such a different color is to make the silver surface and the substrate different in color, but when using a transparent silver surface, it can also be achieved by making the front and back of the substrate different in color. can. Methods of making the front and back sides of the substrate have different colors include: laminating non-woven fabrics with different colors, applying a different color to one side of a colored substrate by printing, etc. In this case, one possible method would be to make the two front and back threads of different colors.

There is still no restriction on the color of the silver surface, and it may be gold-like or silver-like. Moreover, in the case of a colored transparent material, it is preferable because it blends with the color of the substrate and exhibits a unique color.

(Effects of the Invention) The leather-like yarn of the present invention has high strength because it has a silver surface, 2 improves elasticity, 2 is strong, soft, and has good elasticity, and has soft and beautiful stitches (loops). It has the advantage of being obtained.

In addition, it has the following features: 1. Improved elasticity, good stability, and does not lose its shape when worn, and does not lose its shape when washed.

The leather-like yarn of the present invention can be used in combination with other materials.
It is also effective to process it into something suitable for various handicrafts, such as braided cord.

In addition, when it is made into a woven or knitted fabric, each thread is naturally wrinkled, the silver side and the fibrous base side are exposed, and the colors on both sides are added, making it rich in variety. You can get beautiful color effects. Differences in color 1. By changing the knitted fabric, it is possible to emphasize the silver-grained or suede feel. You can still create things with a wide variety of textures and touch surfaces.

Next, embodiments of the present invention will be described, but the present invention is not limited or restricted thereto.

Example 1 Island component is 70 parts polyester, sea component is 3 parts polystyrene
A needle bunch felt was made using 0 parts of sea-island fiber (3.5 d x 51 rsn).

Next, this was simultaneously shrunk and glued in a hot bath of 15% partially cured polyvinyl alcohol, and dried.

Next, polystyrene was extracted and removed in a trichlene bath and dried. Furthermore, it was impregnated with a 12% DMF solution of polyurethane and coagulated in water.

Thoroughly washed in hot water. After drying, both sides are puffed with sandpaper and dyed at high temperature and pressure using a jet dyeing machine to a thickness of 0.6 r.
A fibrous substrate having a basis weight of 23 D vm2 was obtained.

A silver surface was applied to this substrate in the following manner.

A solution consisting of a one-component polyurethane and a pigment was applied to a 1ill pattern paper having an old grain pattern and dried to obtain a film of about 5.0 p. Furthermore, a solution consisting of two-component polyurethane and pigment is applied on top of this, and the substrate is pressed in a semi-dry state.
After drying, the release paper was peeled off to obtain a substrate having two silver surfaces on one side. Furthermore, the above-mentioned operation was repeated to obtain a material having a silver surface on one side. The thickness of this item is 0.7 mm.
The area was 250g and 7m2.

Next, this was cut into a width of 1.5 mm using a slitter to obtain two leather-like yarns of the present invention (as shown in Fig. 1).

Various interior items such as clothes, handbags, and sofa backs were knitted using various combinations of base and silver surface colors.

It has a three-dimensional feel, has stretch back properties, and is a mix of elegant luster and color. I got a product that feels luxurious. ′＝
