Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a synthetic fiber napkin that has a texture similar to natural fur.

BACKGROUND OF THE INVENTION Conventionally, synthetic fibers such as nappy wool have been widely used as artificial fur in the form of cut pile products such as boa, seal, high pile, and russell for coats, linings, hats, slippers, rugs, toys, etc. As the demand for these raised fur products increases year by year, there is a trend toward luxury products, and recently, there has been a strong demand for the appearance of full-fledged raised products that resemble natural fur.

Against this background, with regard to pile surfaces, various studies have been made and numerous patents have been filed, particularly with the aim of forming piloeres similar to animal hair. For example, many other methods have been proposed, such as Special Publication No. 48-2091, Hakama Publication No. 49-45743, Special Publication No. 52-1095, etc., and recently, many products similar to natural animal hair for the raised surface have begun to appear on the market. .
However, the back side of the nap has rarely been studied in the past, and the only treatment that has been done is to prevent the nap from falling through by packing from the back side.

For this reason, the back side has an artificial and cheap feel compared to the high-class feel of the napped side, such as the deterioration of the texture due to packing and the exposure of the base fabric on the back side.

In addition, in many cases, these products are made by sewing a lining on the back side or laminating them with another base fabric.

In the future, as the use of these raised blankets expands into fields oriented to luxury goods such as interior decoration, clothing, and toys, it is clear that there will be a demand for products similar to natural warp hair, and for this purpose, It is thought that the development of natural domestic animal hair products by improving the surface will be important. The present invention provides a method for manufacturing a full-scale animal hair-like nap curtain that has an animal hair-like feel and a suede-like feel by improving the nape surface, which has not been studied in the past. 1. The gist of the invention is that after a sand sheet made of ultrafine short fibers with a total weave of 0.8 denier or less is superimposed on the back side of a synthetic fiber napping cloth, 5 to 100 kg of crucian carp is passed through a nozzle. An animal hair-like nap blanket belt characterized by intertwining the ultrafine short fibers of the sand sheet and the fibers of the synthetic fiber nap blanket by applying a liquid stream jetted at a pressure of The gist of the second invention is to produce a fabricated sheet made of ultra-fine short fibers with a total single fiber twill of 0.8 deniers or less, and to produce a fabricated sheet made of ultrafine staple fibers with a total twill of 0.8 deniers or less. After stacking it on the back side of the
An animal hair preparation method characterized in that ultrafine short fibers constituting the made sheet are intertwined with the usual constituent fibers of the raised fabric by applying a liquid flow jetted under the pressure of the ground to the surface of the made sheet, and then subjected to a shrinkage treatment. It is in the method of manufacturing blanket curtains.

To explain the present invention in more detail, in the present invention, in particular, the single fiber weave is 0.

The reason for using ultrafine staple fibers of 8 denier or less is that while they have a natural leather-like feel, it is generally necessary to use fibers of 0.8 denier or less in order to achieve a particularly suede-like appearance and texture. This is because it is difficult to achieve the desired natural leather-like effect with a weave greater than this.

The ultrafine short fibers used in the present invention are not particularly limited, and may be produced by any method.

As an example, there are the following methods.

That is, a method in which a fiber-forming polymer is wet threaded using a threading nozzle made of a metal fiber sheet with a precision of 15 degrees or more, drawn, and cut.

‘.

} After super-stretching the undrawn polyethylene terephthalate yarn,
The method is to cut the film, or to carry out normal stretching after ultra-stretching, and then cut it. The fiber length of the ultrafine short fibers is determined based on the relationship between dispersibility in liquid during the papermaking process, papermaking properties, entangling properties by liquid jetting, shedding properties from the obtained product, and the feel of the obtained product. There is no particular limit, but considering the above properties, 0.5
~0.8 denier ultra-fine short fibers are 2 to 1 long, 0.2
For denier, 2 to 5 pieces, and for 0.05 denier, 1 to 3 pieces is appropriate. The reason why a paper-made sheet is used in the present invention is that it is extremely difficult to directly form ultra-fine short fibers into a sheet, and the ultra-fine fiber sheet obtained by wet paper-making is relatively delicate. This is because it is suitable for exerting its effects.

As a method for producing a paper sheet, first, the ultrafine short fibers are mixed into a liquid (water is generally used as the liquid, but any liquid may be used as long as it is not a solvent for the fiber polymer).

). When using water, the fiber concentration in water is 0.001% to 0.0 from the viewpoint of dispersion in water, uniform papermaking, etc.
Approximately 5% is appropriate.

The dispersion thus obtained is formed into a sheet in the next step. After this Myozo sheet is superimposed on the back side of the synthetic fiber napped product, it undergoes the injection liquid treatment described below.

The synthetic fiber standing blankets include /・pile, boa,
Seals, russells, and other ultra-hair products are used, and these are provided in tip-liang products or in an undyed state. Further, by appropriately combining the base fabric density of the raised blanket and the jetting liquid treatment conditions described below, it is possible to provide a considerably wide variety of final products in terms of performance, feel, and response. In addition, when fibers with latent shrinkage properties, such as high shrinkage acrylic fibers and high shrinkage polyethylene terephthalate fibers, are used as the base fabric of the raised fabric, the ultrafine short fibers and these base fabric constituent fibers become intertwined and integrated. After that, it is made finer by shrinkage treatment, and the ultra-fine short fibers are distributed in the base fabric at a high density, making it possible to obtain a product that has a feel more similar to that of natural leather and has a suede-like feel. In the present invention, the ultra-fine short twill paper-made sheet and the synthetic fiber napping fabric are integrated by a liquid jetting process. In the liquid jetting process, liquid is directly jetted onto a support member such as a net or roll while the napped surface is in contact and/or both ends are gripped.

In this case, any support member may be used as long as it has a substantially smooth surface, the pattern of the support member does not always form on the raised surface, and the ejected liquid can be quickly removed. be able to.

Also, in the case of online treatment, water can be removed more effectively by using suction.

If the support member has large irregularities, it is not preferable because a pattern will be formed on the sheet surface by the liquid jet treatment, and the disturbance of the naps that normally occur in the napping fabric will become large. Although any liquid other than the solvent for the treated fibers can be used for the liquid jet treatment, water or warm water is preferred because of its ease of handling.

It is also possible to add a small amount of additive to the liquid to increase the effect of fluid jetting. The water jet to be jetted may be in the form of a columnar flow, a fan flow, or a slit flow, but a columnar flow is more preferred to achieve this purpose. The hole diameter of the nozzle that injects the liquid is usually 0.06 to 1.0 mm in the case of columnar flow. Vengeance, preferably 0.1
~0.3 willow, and in the case of a fan flow, it is 0.1 to 0.2, preferably 0.5 to 1.5 side. The pressure of the liquid used is usually 5 to 100 k9/m, but it is determined depending on the processing speed, confounding effect, and other factors.

If the pressure is too low, a sufficient entangling effect will not be obtained, and if the pressure is too high, it will not only be economically disadvantageous, but also leave traces of fluid treatment, destroy the shape of the ultrafine short fiber layer, and seriously damage the other side. Undesirable. In general, a weight of 5 to 35 kg' is more preferable to enhance this effect. If the product once obtained in the above process is further laminated with an ultrafine short fiber sheet from the back side and the liquid injection treatment is performed again, the proportion of ultrafine short fibers in the napkin will increase, resulting in a high density and A product with a slimy feel similar to animal hair can be obtained.

The composite napped product thus obtained is directly dried.
Further, when a fiber having latent shrinkage is used as the base fabric material, it is dried after being subjected to a shrinkage treatment such as a steam treatment or a wet treatment. Then, a treatment with a packing agent may be performed as necessary. This packing treatment should be limited to a level that does not impair the texture, and in this respect, polyurethane resins are suitable. Furthermore, if necessary, it is also possible to perform light raising treatment such as buffing on the wavy surface.

The present invention will be explained in more detail with reference to Examples below. Example 1 An acrylonitrile-based copolymer containing 9 boxes weight % of acrylonitrile and 7 weight % vinyl acetate and having an intrinsic viscosity of 1.7 as measured in 25 qo dimethylformamide was dissolved in dimethylacetamide to give a polymer concentration of 16 weight %. The stock solution was prepared, and as a spinning cap, two sheets of Pall filter rigid mesh sheets (manufactured by Pall, Trinity, and Micro Co., Ltd.) with 5 degrees of precision were stacked together using stainless steel fibers. The paper yarn was wet-laid in a 35q0 aqueous solution containing 6% by weight of dimethylacetamide at a take-up speed of 5 min.

Subsequently, the tow was stretched 3 times in boiling water to obtain an ultrafine fiber tow with an average single fiber weave of 0.1 denier and a total fiber count of 4200 denier. This tow was cut into three willows and placed in water to form a dispersion having a fiber concentration of 0.01% by weight.

This dispersion was drawn up to obtain an acrylic ultrafine short fiber sheet. On the other hand, after mixing dry acrylic fibers with single fiber fineness of 15 denier and 8 denier with high shrinkage wet acrylic fibers of 3 denier as a synthetic fiber napping pile, rare wool yarn 2
/24MC was embossed, and while weaving a double pile cloth using a pile loom, the central part was cut with a knife to obtain two seal fabrics with a pile length of 2 mm. This greige fabric was used to perform animal hair-like printing on the pile surface, followed by soaping drying, hair splitting, and first-stage polishing. After the paper sheet was superimposed on the back side of the synthetic fiber napped product, it was placed on a 200 mesh wire gauze and water jet treatment was performed from the side of the acrylic ultrafine short fiber sheet.

In the water jet treatment, a water jet was jetted at a pressure of 25 k9/c fin G using a liquid jet nozzle with a hole diameter of 0.15 legs and a distance between holes of 1 inch. The distance between the spray nozzle and the sheet was set to 4 degrees, and the wire mesh carrying them was moved at a speed of 2 degrees per minute. The laminate was then introduced onto a metal roll with a diameter of 20 mm and a similar nozzle was used to direct the laminate to a height of 4 feet above the sheet.
After spraying water at the pressure of ○, it was dried. Thereafter, the pile surface was polished again to obtain a final product. Because the back side of the resulting product is covered with ultra-fine fibers, it has an extremely slimy natural leather-like appearance and texture, and is a genuine animal hair-like product that is even more luxurious than conventional products. It was a refined product made from raised cloth.

Example 2 Two 1/3 MC semi-flowable yarns mixed at a ratio of 6:4 with acrylic staples of 23 denier and polyester staples of 6 denier were tied together and tufted into an acrylic fiber fabric with a boiling water shrinkage rate of 25%. After making that pile cloth with a high pile of 4 broadsides and a basis weight of 800 ta', I split the pile and applied a polisher to the pile.

A Myozo sheet made from the same machine as that used in Example 1 was superimposed on the back side of the obtained cloth, and then subjected to the same water jet treatment as in Example 1, and after drying, shrinkage treatment was performed using steam.
