Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a napped product, particularly a product having excellent appearance, feel, and light JIl: napped hair.

Pile like cut pile or loop pile
One of the purposes of manufacturing products in the south is to obtain fur-like products. However, as is well known, natural fur has complex, subtle, and sophisticated colors, layers, and structures, and it was extremely difficult to create such things artificially. et al. researched the manufacturing method of advanced napping products similar to natural fur, and published 41141-15486 and 1982-57554. This was proposed in No. 56-49048. The present inventors have conducted repeated research on improving piloerection and have arrived at the present invention.

The first object of the present invention is to provide a product that closely approximates natural high-grade fur - excellent appearance, feel and light weight. Another object of the invention is to provide a product that has a high degree of appearance and feel that differs from natural fur.

In the napped product of the present invention, at least a part of the napped part is made of a specific flat yarn. That is, the product of the present invention is
It has six protrusions that are arranged at an angle of 90 to 180 degrees to each other in the cross section and taper toward the tip, and the length of the other protrusions is 1.5 to 4 times the length of the shortest protrusion. It is characterized by being made of a certain flat thread and having a thinned nape at the tip.

FIG. 1 is an example of a cross section of a normal thread with a modified cross section having three protrusions. Stripes 2 to 6 are 1- out of 6 XA occurrences.
This is an example of a cross section of a flat yarn suitable for the present invention, which is shorter than others.◎Here, a protrusion is an example of a cross section of a flat yarn that is outside the largest inscribed circle (hereinafter simply referred to as a homotangential circle) of the cross section of the fiber. ' or a protrusion that touches that circle. In the figure, the inscribed circle is shown by a dotted line. Figure 2 shows an example in which three protrusions (tl, (2), and (5)) are all outside the inscribed circle, and Figure 3 shows an example in which 2 orchid protrusions are outside the inscribed circle and 1 This is an example in which the individual pieces extend around the inscribed circle.The distance between the center 0 of the inscribed circle (hereinafter referred to as the center) and the tip of the protrusion is the length of the protrusion.In Fig. 2, the shortest The length of the protrusion (1) is indicated by 21, and the length of the long protrusion (2) is indicated by 1/, 2, and 25.The ratio of the stiffness of the other protrusions to the shortest protrusion, that is, Q2/ λ1 and n S
/Q 1 - roughly about tz, ta. The length ratio of this protrusion is approximately 50 in Figure 3 and approximately 2.1 in Figure 4.
゜In Figure 5, it is about 2-5. In FIG. 6, they are about 2.0 and about 40.

The raised hairs of fur products, especially the prickly hairs (bristle) K, are required to be hard to place and flexible, as well as high covering power and plushability. The present inventor, Hiromu, has discovered that a product excellent in the above-mentioned properties can be obtained by making the cross section of the nape specific as described above, that is, asymmetric and flat.

For example, the figures in FIGS. 2 to 4 are horizontally symmetrical or vertically asymmetrical, and those in FIGS. 5 to 7 are asymmetrical both vertically and horizontally. Moreover, the maximum diameter (major axis) and minimum diameter (
For example, in Fig. 1, the oblateness ratio is about 1.5, but in Figs. 2 to 6, it is about 2.0%. Ll, 2. b, 2.5.2. υ
, 2.2.

High flatness - It is easy to bend in the thinner direction, is flexible, and has a large brazing force, but if the flatness is too large, it becomes excessively soft and loses its elasticity.In the end, the flatness is 1.7 ~
The most preferable value is about 4, especially about 2 to 3.Furthermore, flat yarns like those shown in Figures 2 to 6 are easy to bend in the thinner direction, but when bent with the shortest protrusion (1) on the outside, they are softer and vice versa. When you try to bend a short protrusion on the inside, there is a large (hard) resistance when you try to bend it.Moths are also easy to bend in one direction.The surface of the protrusion (1) (upper part of the figure) is the 2nd side and the opposite side. jI]li (lower part of the figure) is called the G-plane, it is softest if the y-plane is bent by applying pressure to the outside, and hard if the G-plane is bent outward or in the thickness direction. For this purpose, for example, if you brush a raised product made of such threads,
On the outside (surface) of the fur, the raised hairs are often aligned by 0 or plush, which gives the fur a very supple feel, a uniform appearance, and enhanced covering power.

Similarly, by combining two components with different eccentric K (asymmetrical K) shrinkability in the thin direction, it is possible to impart spontaneous crimpability (in most cases, weak and gradual crimpness is achieved). For example, it is possible to obtain an astra-like product.

In this case, it is preferable to arrange the shrinkage component on the 0-plane side.

In order to provide the preferable asymmetric properties as described above, the mutual angle of the three protrusions must be 90 to 18 degrees, and preferably 10 to 150'. Here, the angle between the protrusions and the straight line connecting the shaft center 0 and the tip of the protrusion is the angle formed by the straight line connecting the protrusion center 0 and the tip of the protrusion. The angle is about 1300
．． The angle between the same <(S) and (1) is 1100.

Similarly, the larger the ratio of the length of the other protrusion (23° (3) /It1* ”/l) to the shortest protrusion (1), the more curved it becomes with the F2 side facing out, but this ratio If it is too large, it will be too soft.That is #2/g, 1゜MS
/Q 1 is preferably in the range of t5 to 4, particularly preferably in the range of t7 to 5.

As is well known, high-quality fur has a beautiful luster.・In order to obtain a strong gloss, K should use fibers that do not contain matting agents or contain only a small amount of matting agent, but in that case, the transparency of the nap will be too high and the covering power will be poor and the appearance will be poor. White products have poor sunlight resistance, and if fibers containing a lot of matting agent are used to improve the coating color, the gloss will be lost.

The inventors of the present invention have already discovered that by using composite fibers in which a transparent component and an opaque component are combined for napping, a napping product with excellent gloss and covering power can be obtained. proposed. Figure 2 shows how such composite fibers can be applied to the present invention.
Iris 6- is an example of a composite fiber containing a transparent component (fJIIIlt) and an opaque component (B).

The transparent component must have excellent light reflectivity (gloss). In other words, the content of the matting agent is α6% (]1
Ejit) or lower, special K (LIX or lower is preferable (LO5)
% or less is most preferable.However, in order to obtain a soft gloss, for example, a matting agent of about 101 to 0.5% can be added.Similarly, it is possible to add a matting agent of about 101% to 0.5%. Therefore, a matting agent of 3% or less can be added.

The opaque component must have excellent light-shielding properties (scattering, absorption).In order to increase the luminosity, it is necessary to incorporate matting agents, pigments, etc., and to have a large number of microscopic bubbles. There are methods such as creating a porous structure.

Examples of matte elbows include white powders such as titanium oxide, zinc oxide, magnesium oxide, aluminum oxide, barium sulfate, and silica. Colored particles (pigments) such as iron oxide are used in carbon bra, for example, for yellow to reddish brown fur.

It can be used for brown to black or dark colored fur, but it is less versatile than white fur.The matting agent or pigment mixed group needs to be larger than the transparent component by α3% or more.* α to III
5% or more is preferable, and the strongest light-shielding property can be obtained at about 1 to 10%. ◎To make the opaque component porous, there are many methods of foaming it by mixing a foaming agent, but in general, it requires a lot of spinning. However, it is relatively easy to disperse the second component, mix and spin it, and extract it later. Although it is difficult to make the opaque component porous as described above, it is most preferable from the standpoint of heat insulation and light weight.

Various applications are possible for the transparent component, opaque component, and zero composite shape F1. Figures 2 and 5 are core and sheath, Figure 4 is radial, and Figure 5 is side pine.

Figure 6 is an example of a three-layer composite. 50% or more of the fiber surface area to obtain excellent gloss.

In particular, the transparent component must account for 60% or more.

The majority of the special KF surface is, for example, 70% or more, especially 80 to 100%.
It is preferable that the transparent component accounts for %. G, 1IIi may be a transparent component or an opaque component. Figure 5 is an example in which most of the 0 plane is occupied by the opaque component.◎ In order for the opaque component to be fully effective, the area ratio occupied by the opaque component when viewed from the thin direction, that is, the opacity. must be 30% or more, especially 50%
% or more is preferable, and 70% or more is most preferable. The opacity is determined by Kitamoto Y/XX100 (%) of both types Y occupied by the opaque component, relative to the total area of the fiber seen through the fiber from the thin direction, for example, XK in Figure 2.Each protrusion is It's getting thinner. If there is a constricted portion that protrudes and has an extremely small width, when the tip is made thinner, the tip will be divided into multiple parts, which will spoil the appearance. FIG. 7 is a perspective view showing an example in which the tip of the fiber as shown in FIG. 3 is thinned, and there is only one tip. The thinned tip of the fiber of the present invention is often located at or near the center 0, giving it a moxibustion-like appearance.

Napped products, especially fur-like products, can be produced using so-called pile knitting machines, pile loom women, etc., sly/(knitting machines, electrostatic flocking methods, etc.)
Manufactured by tufting, raising and other similar methods. The part of the artificial part that corresponds to the skin part of fur is called the base fabric. The base fabric is knitted fabric, woven fabric, non-woven fabric,
It consists of films, sheets, artificial leathers, and similar materials, and may or may not contain elastic materials such as polyurethane elastomer, synthetic rubber, or natural rubber, or non-elastic resins.

The component that forms the nape is polyamide.

Polyester, polyvinyl, polyacrylonitrile, polyolefin, polyurethane.

All kinds of fiber-forming polymers can be used, such as polyethers, regenerated cellulose, etc. Spinning--re J-melt, wet, IIL, and all other methods can be used.

The tip of the raised hair must be thinned. The shape of the thinning is free, but it is preferable to have a smooth thinning as shown in FIG. Similarly, step by step (multi-step)
It is also preferable that the material is finely divided. In order to make it thinner, it is convenient to use navy blue from polyester polymers.

In other words, since polyester fibers are gradually decomposed from the outside by an aqueous alkali solution, it is easy to process the fibers into thinner fibers.In general, when polyester contains a large amount of matting agent, the rate of hydrolysis by alkali increases. There is an inside. In the case of composite fibers, it is preferred that the hydrolysis rate of each component is the same.

This is because the thinning of the tip etc. can be carried out smoothly.

Further, polyester containing a matting agent or other particles can be made porous by hydrolysis, and the porous portion can be used as an opaque component. For example, a side-by-side or incomplete core-sheath type (a part of the core containing the above-mentioned particles is exposed on the surface) K composite of polyester containing silica fine particles in titanium oxide and transparent polyester is treated with an alkaline aqueous solution. , the particle-containing component can be made porous (opaque).

In the case of advanced products, raised hair consists of a double structure of prickly hair and fluff, but a single structure of only fluff or prickly hair is also used.◎Striped hair is thick and long, and is usually not curled or curled. It is desired that the material has weak crimping and that the base of the tip is thin, and that it has excellent gloss and sufficient coverage.

For example, the thickness of the stinging hair is more than 5 d @ degree, @ 4 c 1 oa or more, and in most cases it is about 15 to 100 d, and the length is more than 10 m6, and more than 2081 in 4 I.

Most often between 20 and 100 degrees, dense If
50 to 5,000 wrinkles/-1, especially 100 to 1,000 wrinkles.

The fluff has a thickness of 54 @ [less than 5 d, in most cases α1 to 3 ds straight, the length is 5 m or more, special K 10
ms or more, often 10 to 100111&[,
The density is about 1,000 to 100,000 pieces/cd, and in most cases -s, ooo to 50,000 pieces/cd,
In many cases gloss is not necessary. Of course, piloerection is not limited to the combination of chest hair and stinging hair, but also depends on the thickness, length, and polymer afA.
It is also possible to mix multiple types of different types. For example, products with a variety of colors can be obtained by mixing materials with different dyeing properties. Examples of dyes with different dyeing properties include those with the same dye but with different dyeing speeds, and those with strong dyeing properties for some dyes and poor dyeing properties for other dyes (such as dyes with dye selectivity). 0 acid dyes, -base dyes 5
Using fibers made of polymers with different selectivities for interstitial dyes, direct dyes, etc., for example, they are made into jacquart pile knitted fabrics, and dyed with multiple hectares of dyes to produce a variety of napped products.

In the case of a double structure of chest hair/stinging hair, the fluff is made of normal M-thin fibers, and it is also preferable that only the stinging hair is made of spun flat filaments, or that one of the stinging hairs is made of the said flattened fibers. If all of the fluff is made of ordinary fibers, the appearance may be inferior to e6 even if all of the fluff is made of the flat yarn.

In other words, it is most effective to use grade 9 flat yarn for the prickly hairs that occupy the kana on the front side of the fur because of its excellent appearance, feel, and covering power. That is, more than 25% of the stinging hair, especially 50%
It is preferable that at least % of the flat yarn is comprised of the flat yarn. Even in products where all of the piloerection is made up of prickly hair, more than 25% of the prickles are prickly,
In particular, when 50% or more of the fluff is made up of the flat yarn, an excellent appearance can be obtained. Even in products where all of the naps are made of fluff, it is preferable that 25% or more of the fluff, especially 50%, is the flat yarn. .

The product of the present invention has a supple and firm feel and has raised naps that have a covering power, and can also be provided with excellent gloss if necessary. For this reason, even with a smaller amount of raised fluff, a bulky and voluminous appearance can be achieved, and the weight of the product can therefore be reduced. In addition, the product of the present invention has raised hairs that are arranged in a moderately curved manner by applying external force such as glassing, and has a flexible and beautiful appearance and feel that makes it easy to arrange the raised hairs. .

Subsequently, the yarn Y1 was immersed in a water emulsion containing 15% dial alcohol at 50°C for 1 hour to separate it into polyester and nylon (fibrillation) and to make it ultra-fine (approximately α54).
The fabric is further steamed at 100℃ for 15 minutes in a state containing benzyl alcohol to shrink the base fabric, resulting in a 90-length shrinkage rate of 36% in the warp direction, 47% in the weft direction, and an area shrinkage rate of approximately 65%.
