Description

[Detailed Description of the Invention] The present invention relates to an ultra-fine napped sheet having bulky suede or cashmere-like napped bristles or feather-like napped bristles.

Already has naps made from ultrafine fibers or ultrafine fiber-generating fibers, and the naps have their root parts tied together,
Sheets with naps that are tapered at the tip or branched into ultra-fine fibers are known, and unlike conventional suede with ultra-fine fiber naps, these sheets have a bulky suede-like or cashmere-like nap. It is also known that it is a raised sheet that is extremely unique and has a luxurious feel.

However, since those colored items were monochromatic, cashmere-like, they had a dull, dull feel.

On the other hand, even if you look at the varnished products in the market that use ultra-fine fibers, you won't find anything with a single color that has a calm and varied feel.

What's more, it's suede that doesn't have much bulk, and I can't find anything that has a bulgy feel, or a cashmere-like feel, or something that has a plump feel, like a feather-like print or a mink print. do not have.

However, proposals to release something like that have already begun to emerge.

The present invention takes this a step further, by using a mixture of tied bundles of raised hair that is colored in a unique color to further emphasize the fullness and marbled tone.
It was successful in creating a warm and calming feeling.

Moreover, it has succeeded in making the overall feel more luxurious, and in addition, it has been able to provide a variety of colors and reduce the feeling of colors that tend to fade.

That is, the present invention has the following configuration.

A marbled-looking napless sheet characterized in that, in a sheet having naps with branched tips, bundled naps of different colors are mixed between the bundles.

The present invention will be explained in detail below.

In a normal person's varnish, the marbled-looking raised sheets obtained by mixing groups of raised hairs with different tones have a good blend of colors and are easy to be confused by, but it is possible to emphasize the marbled tones by adding various contrasts. is not suitable.

In the sheet of the present invention, since the roots of the raised hairs are tied together, mixing of branches between the raised hairs of different colors is moderately suppressed, and as a result, the marbling tone can be emphasized.

Furthermore, it has been found that it is more preferable if the color of polyurethane, which is often used for human varnishing, is visible through the nape to the extent that it is not too harsh and gives a multicolored appearance.

The nap of the present invention is produced by bundling the base part and branching the tip by applying a combination of a nap formation process and a nap tip division process to a sheet having ultrafine fiber generation type fibers or bundled bundles of ultrafine fibers. etc. can be obtained by

At that time, by mixing fibers with different colors or dyeability in advance as ultrafine fiber-generating fibers or bundles of bundled ultrafine fibers, it is possible to create a marbled-looking napped sheet with a mixture of naps of different colors. .

Here, the tips of the branched hairs form a single group, and the groups with different tones blend appropriately to create a marbled tone.

As the ultrafine fiber-generating fiber, for example, if it is a sea-island type polymer mutual array fiber, island nylon, island polyester, island polyethylene terephthalate, and the same polymer as the island, ethylene 5-sodium sulfoisophthalate are used. For example, make two types of units that contain units and mix them.

The sea material may be made of any material such as polyethylene, polystyrene polymer, or polyester containing a large amount of ethylene 5-sodium sulfoisophthalate units.

The same applies to not only seabird type composite fibers but also polymer blend spun type fibers that generate ultrafine fibers.

Peelable fibers also consist of a combination of two polymers, whether they have an American-shaped cross section, a hollow chrysanthemum petal shape, or something else.

Looking at the combination of polymers between islands and other islands, one island is polyethylene terephthalate, and the other island is the same polymer with 0.5 to 8 mol% of ethylene-5-sodium sulfoisophthalate units. The sea can be made of common nylon.

The bundle of ultrafine fibers mentioned above refers to multifilaments and spun yarns made of ultrafine fibers, which can be obtained by highly controlled wet or melt spinning methods, as well as by peeling or monofilament from ultrafine fiber-generating fibers. Of course, it can be obtained by component elution.

The above-mentioned meaning ``resulted'' means that a plurality of ultrafine fibers are restrained and behave as a bundle.

For example, it means being joined directly or through another component, or being surrounded by other components.

Materials for ultrafine fiber generation type fibers or bundled ultrafine fibers include acrylic, cellulose, polyamide,
There are polyester types, polyurethane types, etc.

These are mixed into carded cotton, filament mixed, and spun (simultaneously)
They are mixed, etc.

Taking advantage of the differences between these materials, you can dye them by using different dyes, or you can add carbon black or other pigments to the material itself to differentiate the colors, and you can also add dyes on top of that. Good too.

The napping with branched tips can be obtained by puffing or raising a sheet made of ultrafine fiber-generating fibers or bundled ultrafine fibers.

In some cases, it can also be obtained by eluting a portion of the tip of the piloerection.

A bundle of bundled ultrafine fibers can be prepared by adding a water-soluble polymer to a sheet of sea-island fiber in advance or without adding it to the sheet.
It is obtained by forming the intervening component into a bundle of eluted microfibers, impregnating it with a curable polymer such as silicone, and tying it together in the bundle form.

In the above explanation, when the ultra-fine fibers are replaced with normal-fiber fibers, the luxury, suede-like, softness, etc. brought about by the ultra-fine fibers are lost, but the emphasis on the marbled contrast of this invention, It does not lose its bulky feel.

In other words, it is not an essential requirement that the sheet of the present invention contain ultrafine fibers.

Furthermore, it goes without saying that the raised sheet of the present invention may contain a polymeric elastomer such as polyurethane and various finishing agents as required.

Fig. 1 shows a model of the napped sheet of the present invention, where A means the bundled napped colored in the color A, B means the spun napped napped colored in the color B, and the mixed color Or, the entire surface exhibits a marbled tone.

1 means the base of the sheet, and refers to a nonwoven fabric, a woven fabric, a knitted fabric, a nonwoven fabric containing a woven or knitted fabric, etc., and particularly preferably one coated with polyurethane.

Figure 2 shows models of various forms of the nape tied at the base, and in A, 2 means ultra-fine fibers, and 3 means tied up later or as it was originally tied. There is.

It is a model diagram that means that each tip is extremely thin or close to it.

At the mouth, the binding is made of multiple extremely thin pieces, but the number or thickness of the fine pieces or the amount of binding resin decreases at the tip.
It is a model diagram which means that it is in a pointy state 4.

C is a model diagram that means that the base of 5 is located quite low and is partially turned to the side.

2 shows a state 6 in which the end of the bundle remains in n bundles of the next lower dimension.

Figure 3 shows a model in which the bundle of fibers breaks down and falls apart from the root part, as shown in 7.
If all of these are used, the sheet will have a suede-like appearance, so it will always contain raised hairs (as shown in Fig. 2, A9, C, and II) that are tied together at the base.

The more of these it contains, the better. In this case, there must be a difference in the coloring state between part 7 and the part of the raised pile shown in FIG.

One example is a mixture of A-color A piloerection and B-color A piloerection.

Generally speaking, it is sufficient to have the raised hairs of A color A and H2, and the raised hairs of I99 R and H2 of color B.

Different colors include colored and non-colored. In the piloerection of 7, A
The inventors have already said that there are two types of color and B color.
This is a different invention and has just been proposed, so it is excluded.

This is because it is only a suede and does not contain substantially any cohesive roots.

This is also because they differ in terms of the aforementioned effects such as bulkiness, fullness, and luxurious feel.
