Description

[Detailed description of the invention] The present invention relates to a raised cord material.

More specifically, two nonwoven fabric layers are composed of fibers of anisotropic fiber materials, and are laminated with a knitted fabric to form a laminated structure, and in the surface layer, the fibers on both sides of the knitted fabric are substantially The present invention relates to a raised material that does not mix together and has raised fibers of different fiber materials on both sides.

The purpose of the present invention is to provide a fabric with brushed surfaces on both sides, and
To provide a wool-like raised material that has an excellent reversible effect and is dyed in different colors on the front and back sides. Furthermore, if fibers with an average single fiber fineness of more than 0.5 denier are used on one side and fibers with a single fiber fineness of 0.5 denier or less are used on the other side, in addition to the reversible effect, visual and tactile We offer brushed materials with different front and back sides.

The present inventors have conducted studies to add three new functions to the raised material: reversible and different color. However, when a reversible raised cord material is made of fibers of different fiber materials on both sides and dyed, They discovered that even when a small amount of fibers from other fibers were mixed, only a product with an extremely poor appearance could be produced.In order to create a good-looking reversible raised material, it was essential that fibers from other fibers not be mixed in the surface layer. In addition, we found that when the average single fiber fineness of both the front and back fibers exceeds KO,5 denier, a raised material with a raised state and feel similar to that of a raised wool product can be produced. In addition, if the average single fiber fineness of the fibers on one side of such a raised material is set to 5 denier or less, one side has a surface similar to that of a wool raised product, but the other side has a completely different surface. We discovered that we can create a raised material that gives a textured surface, and as a secondary effect, because we use yarn with an average single fiber fineness of over 0.5 denier, the impregnation speed of the im-like elastic body is extremely fast. We have discovered that this is the case, and have arrived at the present invention.

In other words, the present invention interposes a diaphragm-like elastic body in the interstitial gap of a nonwoven fabric structure consisting of a nonwoven fabric layer formed by intertwining fibers and a knitted fabric existing between the nonwoven fabric layers. In raised materials with raised fibers, the nonwoven fabric layers present on both sides of the knitted fabric are composed of fibers of different fiber materials, each dyed in different colors and with an average single strand of fibers on at least one side. The degree is 0.5 denier,
The □ fibers adjacent to the knitted fabric are intertwined with each other at 1'1', where a part of the fibers enters the weave of the knitted fabric, and the knitted fabric is The fibers of the nonwoven fabric layers on both sides of the fabric mix with each other near the knitted fabric, but there is virtually no mixing in the surface layer, and neither of the two surfaces has a color tone on the opposite side to the knitted fabric. This is a raised material that is characterized by no color turbidity due to the mixing of different fibers.

The features of the present invention are that a nonwoven fabric layer in which fibers of different fiber materials are three-dimensionally intertwined is integrally entangled with each other by embedding a knitted fabric in the middle; (1) If the different fibers of the above are not substantially mixed in the surface layer, knitted fabrics which have greater strength than such non-woven fabric structures and whose both surfaces have different tones. The most important point in achieving the goal of the present invention is the knitted fabric. The reason is that the fibers made of different fiber materials on the opposite side of the type do not mix with each other and form naps on both sides. Only by using K can a heterochromic effect with excellent color tone be obtained. When the two are mixed, it is difficult to dye a completely different color, resulting in a marbled tone or inconvenient unevenness.

However, it is obvious that when the amount of mixture is very small, especially when a small amount of fibers from other fiber materials are mixed in a single filament, it may not be possible to discern the mixture with the naked eye, so mixing at such a feeding rate is problematic. However, it is possible to consciously mix two or more types of fibers on one or both sides, but in this case, the mixed colors will be J! It is a reversible type that meets each other, and even in this case, it is permissible for knitted fabrics as long as the fibers on both sides are not mixed. In addition, from the viewpoint of durability in practical use, interlayer peeling is particularly important to consider. In other words, the bottle must suppress mixing of the fibers constituting the two layers on the front and back sides, and must be bonded to an effective degree of tightness to prevent peeling.

In the present invention, it is necessary that the fibers of the nonwoven fabric layers on both sides are intermixed in the intermediate layer, which means that the interlayers during processing and in the product are overlapped to prevent the phenomenon of It is. Also, one measure of the purity of the mixture can be expressed as ``strong peeling''.

Regarding the food content of the mixture, 50p/cI as a strong peeling force.
R or more is preferable, and in that case, it does not comb during processing, and it has a very strong peeling strength that cannot be combed after filling with an elastic polymer and making it into artificial leather. You can get something. In addition, when the degree of mixing is increased, different types of threads are mixed up to the surface layer k, and the dyed material has different colors in dots, resulting in a reversible raised material that has an extremely poor appearance. Mixing is not recommended. The purity of the mixture is <300 in terms of strength.
It is preferable that it is equal to or less than #/cIt. For this purpose k
For example, when a paper sheet of fibers with a knitted fabric sandwiched between them is to be entangled with a high-pressure fluid stream, care must be taken to keep the pressure at 20#/d or less.

The term "peeling strength" used herein refers to the peeling strength of the laminated entangled sheet in the present invention. That is, it is strong in peeling off the knitted fabric and the nonwoven intertwined body of fibers.

Therefore, if there are any sea components used in the manufacturing process, such as sea components in seabird fibers, soluble filler fibers, or sizing agents such as polyvinyl alcohol, after these are removed, the entangled product will be In general, this is used to determine whether the soluble portion has been removed from an entangled non-woven fabric or from a product sheet filled with an elastic polymer, in which the elastic polymer has been dissolved and removed.

As described above, the nonwoven fabric structure of the present invention can be dyed very easily and well when the fibers of different fiber materials are placed on the front and back sides, and can also be dyed in a knitted fabric in which the fibers of different fiber materials are in the middle. Because they are intertwined with each other in close proximity to each other, non-woven structures made of single I/C fiber materials are extremely strong and strong compared to those made by bonding or other methods. To provide a brushed material with -p! can. Further, in the surface layer, since the fibers of the nonwoven fabric layer on the opposite side to the knitted fabric are not mixed, it is possible to provide a raised material with a mixed color and extremely good color development.

The raised material of the present invention has such a nonwoven fabric structure as a base fabric, and has extremely high mechanical strength because it has no color mixing and has a knitted fabric in the middle. ．． ,
t<f good value. It is a highly brushed material.

In the present invention, the knitted fabric existing in the middle layer of the non-woven fabric structure controls the mixing of the fibers on both sides and intertwines them from the bottle, thereby increasing the strength against cracks and improving dimensional stability. Contribute.

Furthermore, the presence of knitted fabrics plays a major role in facilitating the presence of longitudinal fibers (perpendicular to the plane of the sheet) within the three-dimensional structure of the corpse. This is because the knitted fabric is present inside the fabric, so the fibers inevitably penetrate through the structure of the knitted fabric when entangled. Penetrating this knitted fabric 1. The wedged fibers retain their vertically oriented fibers, provide good napping properties, and improve the compression recovery of nonwovens and raised products.

As described above, knitted fabrics not only provide the strength of the knitted fabric itself to nonwoven fabrics, but also facilitate the presence of fibers in the vertical direction, thereby improving the nonwoven fabrics and the object of the present invention. It works to significantly improve the nap density and physical properties of nap products.

In the raised product of the present invention, there are nonwoven fabric layers made of different fiber materials on both sides of the knitted fabric, and the fibers of these different fiber rope materials are the fibers constituting the knitted fabric. In addition, a nonwoven fabric structure is made in which the fibers on both sides are intertwined near the knitted fabric, but the surface layer ↑ is not mixed.The following is a specific example of how to obtain such a nonwoven fabric structure. The method will be described in more detail.

One specific method for obtaining a nonwoven fabric structure in such a state is to cut the fibers into short fibers of 10 mm or less in length, and then cut the short fibers into a sheet using a wet papermaking machine. Next, a relatively coarse knitted fabric is placed on top, and on top of that, separately made sheets of different fiber materials are layered.
A three-layer laminated sheet product is obtained. At this time, for the purpose of controlling the texture, there is no problem in mixing fiber materials with different solubility that can be removed during the processing process.
For example, short fibers of hot water-soluble polyvinyl alcohol can be mixed into the paper. The amount of paper mixed determines the desired texture of the artificial leather, but if the amount of paper mixed is small, the texture will be hard, whereas if the amount of paper mixed is large, it will have elasticity and a soft texture. Furthermore, since the amount of mixed paper is related to the nap amount of the artificial leather, it is generally preferable to set the amount to 80% by weight or less of the fiber to be made into one paper. Furthermore, by changing the amount of paper mixed on both sides of the knitted fabric, it is possible to balance the amount of nap and texture.

The three-layer laminated sheet thus obtained is placed on a wire mesh having a dehydrating layer on the lower surface, and a high-speed fluid stream is applied from the upper surface while suction is applied from below to entangle the fibers. At this time, if the strength of the cross-body flow is too weak, no entanglement will occur, and if it is too strong, the two types of threads will mix up to the surface, so it is necessary to select favorable conditions in between.゛□''1 The fiber material for the fibers used in the present invention can be any organic polymer substance that has fiber-forming ability.For example, cellulose, cellulose acetate, polyamide, polyester, polyacrylonitrile, polyethylene, etc. , polyzorogylene, polyvinyl chloride, polyvinyl alcohol, or their copolymer polymers.In particular, when two types of fiber materials are combined, depending on the dyeing, matting, and strength, copper ammonia process rayon, and ethylene terephthalate. , nylon-6, nylon 6.6
, acrylonitrile, merical fibers, and copolymers mainly composed of these are preferred. These fibers are
Since it is necessary to intertwine the two types of fiber materials on the front and back sides so that they do not mix, Western-style papermaking is used to obtain a single or one-fiber sheet in order to obtain a strong bond with relatively weak force. In order to obtain a good dispersion state of the yarn in the fiber slurry, the length is preferably 1.0 degrees or less, 10 Io
The length is more than lI. A strong force was required to entangle the threads, and the threads were entangled with the fibers 21J-, which were made of a mixture of two types of threads, even on the surface, resulting in the formation of a skein of threads.

Furthermore, the average single fiber fineness of the fibers must be at least 0.5 denier on at least one side. It is possible to obtain a brushed material with different colors. In addition, if all fibers are 0.5 denier or less, a reversible brushed material with a firm and thick surface can be produced, but this material has a somewhat rough and dry feel, which is the purpose of the present invention. This is not preferable because it does not give a wool-like appearance.

When making the raised material of the present invention using the fibers described above,
The combination of the two types of fiber materials is arbitrary, and any combination is suitable. However, the preferred ones are polyester/cellulose, /Q ester/nylon, /Q ester/polyacrylonitrile, nylon/
Examples include cellulose, nylon/polyacrylonitrile, etc., and generally preferred are combinations of dyes dyed with different properties. In addition, when dyeing with the same dye, the front and back sides have different tones (using the different absorption properties of each component of the blended dye), or the front and back sides have different lightness (using the difference in the absorption properties of the dyes). Of course, a combination of dyes dyed with the same properties may also be used.

When artificial leather with such a combination is dyed, the color difference between the front and back sides is 1z, using the Adams color difference formula according to R Engineering 5-Z-8730 (1970), preferably 3NBS or more, and furthermore, if it is 12MB5 or more, it has an extremely reversible effect. is large. The color difference may depend on K of each of the hue difference, brightness difference, and saturation difference, or may depend on a combination of them. In the present invention, this color difference can be set arbitrarily.

On the other hand, the knitted fabrics, woven fabrics, etc. interposed in the intermediate layer of the present invention require a certain degree of roughness that allows the fibers to penetrate or fill the fabric in an entangled state. te10
It is preferable to select the range from 30 g/- to 7 oy/m2.'r, most preferably from 30 g/- to 7 oy/m2.'r.

Regarding the types of knitted fabrics, there are various types of knitted fabrics such as weft, vertical stripes such as tricot knitting, lace knitting, and various knitted fabrics based on these knitting methods, as well as plain weave, twill weave, satin weave↓, and those based on these weaving methods. Various types of textiles can be mentioned, but
having surface stitches and textures that allow the fibers to embed within the tissue;
In addition, it may be of any type 1 as long as it has a knitted structure that also has voids inside. The fibers constituting the knitted fabric may be any fibers that can be knitted or woven, such as synthetic fibers such as polynyester and polyamide F, and regenerated cellulose fibers such as rayon and Cuprahiko. It is preferable that there be.

In the present invention, it is preferable that the basis weight of the knitted fabric does not exceed 40 times the basis weight of the entire structure. However, the present invention is a nonwoven fabric structure in which an imme-like elastic body is interposed, and the surface is raised with something like sandpaper or a wire brush. It is a brushed material.

The imme-like elastic material may be anything that is used in ordinary nonwoven fabrics, such as polyacrylic acid, polyurethane, NBR, 8BR, polyamino acid, and the like. These imme-like elastic bodies fill the empty FJK of the fiber tissue of the fiber structure, and its state can be arbitrary, but from the viewpoint of texture and napping, it is not directly bonded to the fibers, but is in a state where it is somewhat stiff and dissociated. It is preferable to intervene. This increases the degree of freedom of the fibers, making the texture softer, and
This is preferable because it becomes easier to raise the hair during the raising process. For this reason, before inserting K into the imme-like elastic body tube, a substance that is highly soluble in the solvent for the imme-like elastic body, such as polyvinyl alcohol or sodium salt of carboxymethylcellulose, is attached around the fibers. You can leave it there. Furthermore, the texture of the product can be adjusted by controlling the coagulation structure of the imme-like elastic body. In general, when solidified in a porous form, the elasticity of the male elastic body, such as its ability to recover from compression, etc., is extracted.Therefore, the soft elastic body impregnated with k, As a solution of dimethylformamide, dimethyl sulfoxide, etc., it is prepared to create pores from which the solvent is removed when solidified, and as a water emulsion, a solution of /Q urethane is used to create pores in the same way. As mentioned above, fibers that can be removed after interposing a bim-like elastic body such as polyvinyl alcohol fibers may be added to the nonwoven fabric structure in advance during its fabrication.

This allows many fiber voids to remain, resulting in a raised material with a desirable texture.

Furthermore, when the surface is brushed with sandpaper or a wire brush, the fibers are raised. This can be done after impregnating the bim-like elastic material, but before impregnating the bim-like elastic material. The material may be subjected to a napping process, and the napping may be treated with polyvinyl alcohol, sodium salt of carboxymethyl cellulose, etc., and then impregnated with an imme-like elastic body.

The raised material of the present invention is raised on both sides, and either side can be used as the front surface, and the front and back sides are dyed in different colors, so it is possible to provide a product with different colors on both sides, that is, reversible. The present invention will be explained in more detail by giving examples based on the diversification of the product and its multiple uses. In addition, in the present invention, "9 strong strength" refers to the value measured as follows. To tell.

The nonwoven fabric structure from which components other than knitted fabrics and fibers have been removed is cut into lengths of 20α and width of 2.5zK, and the ends are p5ct.
Discard knitted fabrics up to xO. Holding both sides of the stubble, comb through it with Tensilon for an additional 10 clR, and measure the strength at that time.

Up to 3 of the strongest peaks recorded in the battle yard
The average value of a total of 6 locations (6 locations and a minimum of 3 locations) is calculated using a width of 1. O.C.
Convert to R's strength. This value is called ``Haguri Power''.

Example 1 Copper ammonia method rayon yarn 120a/12'Of was cut into short fibers by 5 mk using a cutter. 500 g of the obtained short fibers and 500 g of fstnyl alcohol fibers cut into a length of 3 m were stirred into 5001 water and added from the top to form a dispersion. Next 0.5 aqueous solution 2! was added to make a slurry liquid. This slurry liquid was made into paper using a hydroformer type inclined fourdrinier paper making machine with a basis weight of 120 g/-
A short fiber paper sheet was obtained. Similarly? Polyethylene terephthalate yarn (75 (1736f) was cut into 5 m lengths with a cutter to create short fibers KL, this short fiber 500II, and 500 g of ribinyl alcohol fibers cut into 3 lengths were stirred in 5.00 mm of water. A dispersion liquid was prepared by adding the bottle.

Next, to this dispersion, 50.9 of Homeless P-46 (manufactured by Keiho Kagaku) and 20.9 of Hexethylene Gelicol Mono p-7 Nylphenyl Ether 409 of 2-e phthadecenyl-6-carzaethoxyethyl were added. 0.5 of Ikidacillin sodium and polyacrylamide (Keiho Kagaku)
1 and 2 parts of an aqueous solution were added to prepare a slurry liquid. This Step 2 liquid was made into a paper using a hydroformer-type inclined fourdrinier paper making machine, and a short fiber paper having a basis weight of 120 g/- was made into a sheet 4. 2゜work. . □Ko1□, 4o.

Three layers were laminated with the polyester paper sheet side as the surface and the polyester paper sheet side as the surface. This sheet with a laminated structure is placed on a wire mesh having a suction device with a perforated plate at the bottom. High-pressure water jets are continuously sprayed at a pressure of D8Icg/- once on the front and back sides, then twice on each side at a pressure of 10ky/d, twice on each side at a pressure of 15Icg/d, and then twice on each side at a pressure of 15Icg/d, then 8icg/cII. ? 1 time each side with 8 kg/an” of ice
I guessed it one time at a time. When the cross-section of the sheet treated with high-pressure water jets was observed using a scanning electron microscope, no three-layer structure was observed, and the fibers were intertwined with the fibers forming the plain weave.
Furthermore, through the woven structure, there are threads oriented in the vertical direction.
The resulting non-woven sheet material was three-dimensionally entangled and could not be peeled off by hand, and even after removing the water-soluble portion, the strength was 10 Cl/-. □・l After brushing this non-woven material with sandpaper to make the fibers and polyvinyl alcohol fibers stand, what should you do so as not to disturb the naps? Rivinyl alcohol (Japan Synthetic Chemical System,
Esenol Gb-05) aqueous solution was deposited and dried, and 10 weight of the solid was deposited on the non-woven fabric. Next, an aqueous solution of sodium salt of calcium chloride cellulose adjusted to 200 voids was applied to the polyester side and dried. What did you get after doing K like this? A 151 MF solution of polyurethane elastomer was impregnated and excess polyurethane was squeezed out through a mangle and then coagulated in water. The polyurethane was impregnated extremely uniformly, and no areas with poor impregnation were found.Furthermore, the vinyl alcohol fibers mixed into the paper during paper making and the adhesion of the fibers were not found. Rivinyl alcohol and the applied sodium salt of carboxymethylcellulose were dissolved and removed with hot water.

After drying, it appears as a brushed surface with a wool-like surface, and the back side is treated with a brush to create a brushed finish.
The adhered polyurethane debris was removed, leaving a brushed surface. The raised material according to this example exhibited the following physical properties.

Weight: 11 220 g/vn” thickness

40 This brushed material is treated with disperse dye, Resolin Navy Del-G.
When the polyester was first dyed blue with LB and then the cupra yarn was dyed red with the reactive dye Remazol Red B, the front and back sides of the raised material were dyed very vividly without any color mixing. Further, in the cross section, it was observed that there was a mixture of two colors in the intermediate layer, and a mixture appeared in the first surface layer.

When I measured the Adams color difference between the front and back sides using a colorimeter, it was 32.
11B8, and was a raised material with a Lipersidel effect that produced very good color.

Comparative Example 1 After obtaining a paper sheet exactly the same as in Example 1, it was similarly laminated into three layers and subjected to an entanglement treatment using high-pressure water jets. At this time, the water pressure was first 2QAcp/c/ for the front and back once, then 40ky/d for 2 times for the front and back, and then 60k/d.
This was done once on each side at a pressure of y/ct'. Although the cross-sectional state of the sheet thus treated was the same as in Example 1, the peel strength was extremely high and could not be measured by cutting the sheet. When this non-woven fabric material was subjected to the same post-treatment as in Example 1 and the same dyeing treatment, threads of different colors appeared in dotted lines on the front and back surfaces of the raised material along the trajectory of the high-pressure water stream. The result was a raised material that was visible and extremely unattractive.

This is presumed to be due to the fact that the water pressure when intertwining the yarns was too high, and the fibers of different fiber rope materials mixed with each other up to the surface.

Three layers were laminated with the polyester paper sheet side as the surface. This laminated sheet was treated with high pressure water washing according to the method of Example 1. When the cross-section of the treated sheet material was observed under a scanning electron microscope, no three-layer structure was observed, and the fibers became entangled with the fibers that made up the knitted fabric, and furthermore, through the knitted structure, vertically oriented yarns were formed. However, the resulting non-woven sheet-like material was three-dimensionally intertwined and could not be peeled off by hand. The peel strength was measured and was 100g ZcI&.

This nonwoven fabric was treated in the same manner as in Example 1, and an aqueous sodium salt solution of carboxymethylcellulose was applied to the surface. ) was applied thinly and uniformly to the back side. Similar to Example 1, what was obtained by K in this way?

Further, in the cross section, it was observed that there was a mixture of two colors in the intermediate layer, and that there was no mixture of colors in the surface layer.

When I measured the Adams color difference between the front and back sides using a colorimeter, it was 15.
It was a brushed material with an NBB and reperside effect.

These two fiber sheets were mixed with the knitted fabric of Example 2 as an intermediate layer. The nozzle diameter of the high pressure water stream is set to 0.1.
The same processing as in Example 1 was carried out with the change to 5 parts. The obtained product had raised naps on both the front and back sides.

The raised material according to this example exhibited the following physical properties. In addition, even though a fiber sheet with a very high density was used by the melt blow method, no uneven impregnation of f-urethane was observed.

Polyester was dyed a pale del-tone using Sol-79, and the disperse dye that contaminated the nylon was removed by reduction washing with dechlorin, and then the nylon was dyed a pale pink using an acid dye (Mitsui Ashitsu F Milling Red FGK). However, the front and back sides of the raised product were dyed without any color mixing. In addition, in the cross section, it was observed that there was color mixing in the intermediate layer, but less color mixing in the surface layer.

Furthermore, the napping on the front and back sides was very different and had an interesting feel.

Example 4 Polyethylene terephthalate yarn (29cl/288f
) was cut into 3+ol fibers using a cutter, and a mixed sheet with a polyvinyl alcohol fiber basis weight of 80 g/- was made from this yarn in the same manner as in Example 1. The mixing ratio of the mixed sheet and the weight and quantity ratio of polyester yarn to polyvinyl alcohol yarn were set to 8:2. In addition, the tow of viscose method rayon yarn (32000a/32000f) was cut into 5 tomomi pieces with a cutter to make short fiber KL, which was also made from rayon yarn.
A mixed paper sheet was prepared with a weight ratio of yarn to polyvinyl alcohol yarn of 5:50 and a basis weight of 100 I/-. These two fiber sheets were laminated into three layers using the fabric of Example 1 as an intermediate layer, and were subjected to entanglement treatment and processing treatment by the method of Example 1.
