Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for effectively heat-treating a napped structure or napped yarn structure 11, which is formed by nuffing a large number of napped LLI fibers from the base tissue. More specifically, II #! constitutes a napped fiber by applying microwaves to the napped fiber. The present invention provides a technology for effectively heat-treating fibers to improve physical properties such as linearity of fibers.

In the past, many attempts have been made to artificially create raised fabrics that resemble high-quality fur such as mink fur.

For example, in JP-A-57-6173 proposed by the present inventors,
As disclosed in Publication No. 9 (as a fur long pile structure, the fabric is composed of long napped navy blue and short napped navy blue II), and the long one-fleece lli dark blue has a sharpened tip. It was made to resemble fur.

If we were to illustrate a model of the napping structure that applies to such a conventional example, it would be as shown in Fig. 1, in which synthetic fibers J
, Rinaru Sashimi II 182 and It J: Rinaru Sashimi Fiber II #3 consisting of short fiber length is raised. Even with such a structure, there is no problem with the baby cage.

However, such a conventional structure has drawbacks such as the straightness of the napped fibers, such as aggregation of napped Is surfaces and tangles when used. In particular, the fibers existing inside the napped fibers have a significant drawback because it is difficult for heat to pass through from the outside.

Moreover, such problems are not limited to the above-mentioned high-quality raised fabrics, but also generally exist in other commonly used raised yarns, Zu1 blanket fabrics, Tanmo fabrics, and even natural fur. It was also a drawback. In order to improve this drawback, there are methods to apply silicone resin, etc., but as for the means to improve the quality of the wood, there are only four methods that have been proposed to date.

The present invention improves the drawbacks of the prior art.
Microwaves are applied to the constituent single fibers of the single fibers 1 in an effective manner, and heat treatment is applied to the constituent medium fibers 1 in an effective and q-wise manner to improve the linearity and non-entanglement of the constituent single fibers. It is intended to be directed towards.

The method of the present invention is based on the method of the present invention:
A dielectric material is applied to the v1 hair layer of the piloerection body (
1. A method for heat treatment of napped fibers, characterized in that microwave heating is performed under a condition in which the movement of the napped fibers is substantially restrained by the presence of the dielectric substance. ] It is.

The method of the present invention will be explained in more detail below.

In the present invention, the napped yarn refers to a yarn such as a mall yarn. In addition, the raised IM structure can be fabricated with Tough 1~, pile knitted fabric, double raschel knitted fabric, moquette, velvet or other interwoven fabrics, suede, -1111t raised fabric or other fabrics using a napping machine, or electric 1fi fabrics such as flock processing method. Any material may be used as long as it is a blanket, water-punched fabric, natural fur, or a brown jacket having 1 carpuff to 1 uniform shoulder.

The heating mechanism in the method of the present invention is to apply a dielectric material to the raised structure, and to apply microwaves to the raised structure,
A desired heat treatment is applied to each constituent single fiber chick of the C-raised 4R structure through the dielectric material. The dielectric material may be any material as long as it has a dielectric effect, such as water, an organic solvent such as alcohol, or an aqueous urea solution.

Water is preferred from the viewpoint of ease of handling and safety. If a high temperature higher than the boiling point of water is required, a substance with a temperature of 1 dlj or 1 dlj may be used as appropriate.

Furthermore, the frequency of microwaves is approximately 300 Ml-l.
Those having a range of z to 100,100 O0 are preferred, and those commonly used in industrial or household microwave ovens that are used for high frequency microwave ovens can be used.

In the present invention, "restraining the raised binding material 1 with a dielectric material" means, for example, when water is used as the dielectric material,
This refers to the fixation of napped fibers to some extent by water. Therefore, rather than referring to a state in which the napped fibers can move sufficiently in a state with a high bath ratio such as during dyeing,
This is a condition in which the apparent pilami fibers cannot move sufficiently. Preferred methods include soaking the entire napped structure or a portion of the napped fibers in water, then taking them out of the water, and draining the amount of water that falls naturally; 1: Or straightening the hair with a comb or the like without cutting it; After that, microwave irradiation is performed.

According to the method of the present invention, even if the dielectric material has penetrated to the deepest part of the napped fiber layer, each part of the dielectric material instantly generates heat at the same time, which is a characteristic of dielectric heating. Uniform heating from the outer surface to the inner depths can be achieved in an extremely short time. Moreover, the temperature can also be made extremely high.

In order to perform a more uniform heat treatment, the heat treatment may be stopped due to evaporation of the dielectric material in the outermost layer, such as by performing steam heating or placing a cloth impregnated with a dielectric material on the napped fiber M layer. It is effective to use measures to prevent this.

In the method of the present invention, it is easily possible to selectively treat a portion of the napped fiber layer, for example, by applying a dielectric substance mainly to the vicinity of the surface layer of the napped fiber M layer. The main heat treatment should be applied to only one hair (1 Mη) in that part, or conversely, the deep part of the piloerection layer 4
-By applying a dielectric material to J, it is also possible to perform main heat treatment near the root of the X''1 hair. It is also possible to apply heat to the hair to change the direction of the hair.

In addition, by using a substance with a certain degree of viscosity as a dielectric substance and heating the substance (this material) with microwaves while making the napped fiber form f1ζ maintain a specific shape, the napped fibers can be given a specific shape. 31 The 3-haired navy blue used in the present invention is generally a synthetic fiber, but it is particularly limited to 1" 11.. , it can also be applied to natural Ill. In particular,
The method of the present invention is effective for materials using sharpened synthetic fibers because they are easy to bend. In addition, the dielectric substance contains dye ￥ 11, and the dyeing power [bi[-] is also applied at the same time. In the case of dyed hair scraps (or dyed with only dead hair scraps), it is possible to create a natural appearance effect.

Also, if IC1 is necessary, it is possible to heat-treat the ground structure at the same time. For example, in the case of mall yarn, in addition to heat-treating the napped fibers, it is also possible to easily apply heat to the core adhesive yarn. I can do it.

The method of the present invention involves heat treatment of a napped cloth or napped yarn whose best napping length is at least 3 mm, as described above.
Blankets and nap yarns that have a two-layer structure consisting of at least relatively long and thick naps aiming for a natural fur look and relatively short and thin TR hairs. It is preferably used for heat treatment. When targeting mink Ab foxes, generally. The hair length of long hair scraps made of relatively good and thick standing hairs is 10 to 7 Qmm, and the length of short hair scraps made of relatively short and thin v1 hairs is 5 to 4 Qmm.
It is best to have a two-layer structure with a thickness of about 0 mm, and according to the method of the present invention, even on such hairs with long hair length and high hair density, an effective heat treatment (111) can be applied in a very short time. It can be achieved.

Next, the effects of the present invention will be described. In the napped structure obtained by the method of the present invention, the straight line f1 of the single fibers constituting the napped hair is amilted,
In particular, the straightness of the fibers inside the napped portion can be significantly improved. It also has the effect of improving the luster of the napped fibers. Furthermore, the durability of maintaining the straight line 11 is improved, and there is a remarkable effect that the binding strings do not become entangled or bunch together even after long-term use.

Hereinafter, the heat treatment method for the napped layer N layer of the present invention will be specifically explained with reference to Examples.

Example 1 IC+1: Making artificial fur having the structure shown in the model shown in FIG. 1 by the method described in Japanese Patent Application Laid-Open No. 57-61739. The structure of the tufted nape and cotton pilage is as described in the notes.

Thickness/10 (1, Maximum hair length: 26mm.

Material: PBT (polybutylene terephthalate-1~) Cotton napping: Thickness: 1.2d, fA large napping length: 12mm0
Sosho: PFT (Polyethyl Non-Teleph = 9- Total 1 note) This person 2 [Water the entire area of the pils side of the fur to concentrate the pils, and at the same time align the coat with a narrow knife. Excess water was removed. At this time, as shown in the model in Figure 2, the entire piloerection layer is laid down in one direction, and both the piloerection layer and the cotton piloerection layer are in an almost straight state. It is in a state where it is held and restrained by water 4. In this state, put it in a household microwave oven (600 watts) and heat it in the microwave for 60 seconds, then remove it from the microwave, dry the remaining moisture at room temperature, and then brush the hair. I did it.

The artificial fur obtained in this way has a well-aligned coat in one direction, as shown in Figure 3, and the loose curls that the curly hair had before heat treatment have become straight. In addition, in particular, the frizz that was present in the nappy hair before the heat treatment is well stretched out, the tangles and tangles of the fluffy fluff caused by the fluffy fluff are improved, and the tutu of the fluffy fluff increases, Artificial fur that was 10-10% good in terms of appearance, use, Ct wool, etc. was obtained. Furthermore, when this artificial fur was subjected to a practical wearing test, the above characteristics did not change even after three uses.

Example 2 Water was added to the artificial fur sample obtained in Example 1 again, and excess water was removed while smoothing the coat using a fine knife.

After this, the surface of the nap layer was wiped with absorbent paper, and the surface was further dried with a horse towel. The sample obtained in this way is q
It mainly contains residual moisture only deep within the upper layer. This sample was placed in a household microwave oven and subjected to microwave heating in the same manner as in Example 1, and then served.

The artificial fur that was jqed in this way has even more curly hair than that of Example 1, has almost no tangles or tangles, has straight hair, and has a moderate amount of fluff. It was even better than that of Example 1 due to densification. The practicality was also excellent in 1 minute.
- Humans in almost the same manner as in Example 1 except that bulls were used.
I made fur.

After applying water to the entire raised area of this artificial fur by spraying, the coat was adjusted with a comb. The total water cost is about one-fifth of that in Example 1, and the water does not penetrate deep into the hair layer, and the upper part of the surface layer mainly contains water. It is in a state of being.

When this sample was placed in a household microwave oven and heated in the microwave for 30 seconds, hair with improved curl and straightness was obtained.

Example 4 Add enough water to artificial fur made from the same material as in Example 1, and use a comb to make the fur direction different by 90 degrees with the center line as the border (both sides are different from the center line). 45 degrees) to get rid of the piloerection.

Place the sample in this state in a household microwave oven for 90 minutes.
After microwave heating for a second, it was taken out and dried.

The artificial fur obtained in this way was fashionable and had N'L hair texture directions that were different from each other with respect to the center line.
