Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a soft touch of natural fur and a color effect due to a two-layer structure similar to that of natural fur. The present invention relates to a pile composition capable of obtaining a natural fur-like pile product having excellent properties.

[0002]

2. Description of the Related Art Natural fur has a two-layer structure consisting of a guard hair portion and a down hair portion, has excellent texture, appearance, and functionality, and is mainly used for clothing. For example, if mink is taken as an example, it is composed of thin and short down hair that occupies about 70 to 80% and thick and long guard hair that occupies about 20 to 30%, and the down hair makes guard hair. It has a napped shape to support it and also helps blooming. Furthermore, the double-layer structure of down hair and guard hair gives a hue effect and a soft feeling. In order to bring pile products closer to the characteristics of natural fur as described above, various studies have been conducted on pile materials and pile weaving technology.

For example, one of them is a thin and short non-shrinkable fiber and a thick and long non-shrinkable fiber for expressing a napped structure and a two-layer structure of natural fur when manufacturing artificial fur with high pile. This is a method of mixing and producing fibers. However, in this method, the thin and short non-shrinkable fibers do not exhibit a substantially constant pile length, so that a two-layer structure similar to natural fur and a color effect due to it cannot be expressed. It was

Further, a thin shrinkable fiber and a thick non-shrinkable fiber are mixed, and a shrink process is performed after weaving a pile to shrink the shrinkable fiber. Thus, a thin and short pile and a thick and long pile are used. A method for producing a mink artificial fur having a layered structure is also known. However, since shrinkable fibers generally shrink in the dyeing process, they do not have shrinkability after dyeing, and shrink by shrinking after pile knitting and weaving as long piles of non-shrinkable fibers as short piles. It is not possible to use a two-layer structure, and it is not possible to use colored shrinkable fibers by this method. Therefore, the shrinkable fibers used in this method have been limited to the use of only undyed produced color. Therefore, the hue effect is limited, and the soft touch feeling especially required for mink tone and sable tone cannot be obtained, and the color effect due to the two-layer structure similar to natural fur is not obtained, and the blooming property due to the napped structure is also sufficiently exhibited. Not not.

Further, in pile products using the conventional undyed shrinkable fibers as described above, the shrinkable fibers are entangled with each other during shrinkage processing after the pile knitting and weaving, and the shrinkable fibers include non-shrinkable fibers. In the subsequent polisher process, the fiber entanglement is strong during crimp stretching (polishing finish) of the fiber, so that only the part close to the pile surface acts, and the finished state of the napped hair of the pile part is similar to that of natural fur. Remarkably inferior when compared. Also, in terms of texture, it has strong squeaky or rough texture, and the drape property of the pile fabric is significantly lacking, and when it is used as clothing, it does not adapt to the body, its shape is unnatural, and it becomes natural fur. It was extremely inferior when compared.

[0006] Therefore, in view of such a situation, the present inventors
As a result of investigating the causes of these phenomena, we succeeded in solving the problem by focusing on the entanglement resistance between the fibers after the shrinking process which is considered to be the biggest reason. JP-A-60-2090
That is the pile composition disclosed in Japanese Patent No. 48. The pile composition has a shrinkage ratio of 15% or more and contains shrinkable fibers having a static friction coefficient between fibers of 0.230 or less as the fibers of the pile portion in an amount of 20 to 98% by weight.
Since the coefficient of static friction between contracted fibers is small, the entanglement resistance between the fibers during contraction processing after pile knitting and weaving is easy, and the clamp stretching is facilitated by the subsequent polisher processing, and the resulting pile product has an excellent appearance. As for the pile after shrinkage, since the entanglement between fibers is weak, the pile fabric has a soft feel even when folded, and thus a pile having a good drape property can be obtained.

[0007]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of conventional natural fur-like pile products, the present invention utilizes the previously proposed shrinkable fiber to further improve the properties of natural fur. That is, a natural fur-like pile product which has a soft touch of natural fur and a color effect due to a two-layer structure, and which has a raised structure similar to natural fur and excellent blooming property, and such a pile product. It is an object of the present invention to provide a pile composition capable of obtaining.

[0008]

That is, a pile product according to the present invention has a pile portion in which short shrinkage fibers in which colored shrinkable fibers are shrunk by shrinkage processing after knitting of piles and long piles of non-shrinkable fibers are used. It is composed of a pile, and the gist is that the pile length difference between the colored short pile and the long pile is 2 to 70 mm. When the pile length difference between the short pile and the long pile is less than 2 mm, the pile heights of the short pile as the down hair portion and the long pile as the guard hair portion are close to each other, and the step pile effect due to the two-layer structure cannot be expected.
Further, if the pile length difference exceeds 70 mm, the color effect is deteriorated, which is not preferable. In the present invention, a pile product is a sliver made of a fiber material forming a pile portion, a pile fabric is made by a sliver knitting machine using a ground yarn, and a paste is applied to the back surface of the pile fabric and dried. Pile product.

The material constituting the pile portion in the pile product of the present invention as described above is a pile composition comprising a mixture of colored shrinkable fibers and non-shrinkable fibers.

The component of the colored shrinkable fiber used in the pile composition may be a thermoplastic polymer, but is preferably an acrylic copolymer. The composition of acrylic synthetic fiber is AN (acrylonitrile) 30
It is a copolymer composed of not less than wt% and is obtained by copolymerizing AN with one or more polymerizable monoolefin monomers. If the AN content is less than 30% by weight, the texture is far from the animal hair touch, there is a feeling of stickiness and lack of volume, and further, shrinking and polishing are required under special conditions, which is not preferable. .
Suitable as the mono-olefin monomer, for example, acrylic acid ester, methacrylic acid ester, acrylic acid amide, methacrylic acid amide, or their mono,
Alternatively, a dialkyl-substituted product, acrylic acid, methacrylic acid, itaconic acid, vinyl chloride, vinylidene chloride, vinyl ester such as vinyl acetate, vinylpyrrolidone, vinylpyridine, or an alkyl-substituted product thereof, styrenesulfonic acid, allylsulfonic acid, methallyl. Sulfonic acid, paracryloyloxybenzene sulfonic acid, methacryloyloxypropyl sulfonic acid, 2-acrylamide, 2
-Methylpropyl sulfonic acid, or metal salts and amine salts of these. In the present invention, the copolymerizable monomer is not required to be so strict, and any conventional monoolefin unsaturated compound copolymerizable with acrylonitrile can be used.

The above acrylic copolymer can be obtained by a usual vinyl polymerization method using a known compound as a polymerization initiator, for example, a peroxide compound, an azo compound or various redox compounds.

Then, this acrylic copolymer is dissolved in an organic solvent such as acetone, acetonitrile, dimethylformamide, dimethylacetamide or dimethylsulfoxide to prepare a spinning dope. This spinning dope is spun from a nozzle by a conventional wet or dry spinning method, and stretched and dried. Further, if necessary, further stretching and heat treatment may be performed. In this way, a shrinkable fiber can be obtained. The shrinkable fiber used in the present invention has a shrinkage of 1
It is 5% or more. The yarn obtained as described above was
By stretching 1.2 to 4.0 times at 0 to 140 ° C., it is possible to obtain a shrinkable fiber having a shrinkage rate of 15% or more as described above.

As described above, the shrinkable fiber used in the present invention has a shrinkage of 15% or more, preferably a shrinkage of 20.
% Of thermoplastic fibers. The reason for this is that when a pile knitted fabric is finished using fibers having a shrinkage ratio of less than 15%, the pile height of the guard hair part made of non-shrinkable fibers and the down hair part where the shrinkable fibers shrink It can be mentioned that the effect due to the two-layer structure, that is, the step pile effect is lowered when approaching. Further, the reason for using the thermoplastic fiber is that the subsequent polishing effect, that is, the crimp extension of the fiber can be expected by the edged heat roll. The term "shrinkage rate" as used in the present invention means the length of the shrinked fiber that has been subjected to the wet heat or dry heat treatment, the length of the fiber that has shrunk in the pile knitting and finishing process, or a condition similar to the shrinking process atmosphere. The length of the contracted fiber is compared with the fiber length before contraction, and the ratio of the contraction displacement length to the fiber length before contraction is shown in percentage (%). That is, in the present invention, "shrinkage rate of 15% or more" means that either the wet heat shrinkage rate or the dry heat shrinkage rate is 15% or more.

The fineness of the colored shrinkable fiber in the present invention is preferably 1 to 10 d (denier, hereinafter referred to as "d"), and more preferably 2 to 7 d. Further, the fiber length of the colored shrinkable fiber is preferably 20 to 64 mm, and more preferably 25 to 51 mm before shrinking. The cross-sectional shape of the colored shrinkable fiber is not particularly limited, and may be circular, hollow circular, kidney-shaped, cocoon-shaped, flat-shaped, oval, 3-lobed, 4-lobed, 5-lobed, or the like. You can choose from.

The hue of the colored shrinkable fiber of the present invention is
It is selected from real colors and fancy colors that assume natural fur. Colorants for coloring the shrinkable fibers include dyes and pigments, which may be used alone or in combination. As the dye, a general cationic dye is preferable, and as the counter ion, there are chloro ion, alkylsulfonate ion, alkylnaphthalenesulfonate ion, dialkylsulfosuccinate ion, and alkyldiphenyletherdisulfonate ion.
Known pigments include carbon black, organic pigments, and inorganic pigments. In the coloring method, a dye or a pigment is dissolved or dispersed in an organic solvent or a part of the spinning dope, and then mixed with the spinning dope. When the dyeing solution or dispersion containing the colorant is mixed with the spinning dope, it is necessary to mix them uniformly. As the mixing method, for example, the dyeing liquid or the dispersion liquid is directly added to the spinning dope tank and uniformly mixed by stirring, or,
Line mixing using a line mixer or the like is also possible.
Further, there is also a method generally called gel dyeing, in which a cationic dye is used for coloring during the coagulation process of wet spinning. Needless to say, stabilizers, fluorescent pigments, dulling agents and the like necessary for the properties of the fibers may be added to the spinning dope.

On the other hand, the non-shrinkable fibers used at the same time may be colored fibers or uncolored fibers. Further, the uncolored fiber may be used after being dyed by a so-called Overmeier dyeing machine or the like. In the present invention, the "non-shrinkable fiber" has a shrinkage of 1
It means 0% or less. The fineness of this non-shrinkable fiber is 3 to 4
0d is preferable, and 5-30d is more preferable. or,
The fiber length of this non-shrinkable fiber is 25 to 127 m before shrinking.
m is preferable, and 38 to 89 mm is more preferable. The cross-sectional shape of the non-contractile fiber may be selected from a circular shape, a hollow circular shape, a kidney shape, a cocoon shape, a flat shape, an oval shape, a 3-lobed shape, a 4-lobed shape, a 5-lobed shape, etc., but as a guard hair In order to appeal to the eyes, flat and oval shapes are preferable. This non-shrinkable fiber can be used as a mixed cotton of two or more kinds by arbitrarily selecting the fineness, the fiber length, the hue, and the shrinkage ratio.

The pile product according to the present invention is manufactured as follows. That is, after the colored shrinkable fibers and the non-shrinkable fibers as described above are mixed, a card sliver is produced through an opener and a card. Then, sliver knitting is performed with a high pile knitting machine.
Here, in order to obtain a color effect due to the two-layer structure and a structure similar to natural fur, prepolishing and pressureing are particularly important steps. After the pile length is made uniform by shirring, the back surface of the pile is coated with an acrylic ester adhesive or the like. At that time, steam is sprayed on the back surface of the pile fabric to shrink the shrinkable fibers in the pile portion to form a colored short pile and enhance the adhesiveness of the adhesive. Then, for example, 130 ℃ ×
Dry for 5 minutes and complete shrinking process. After that, high temperature (140 to 165 ° C.) polishing and brushing are performed, and medium temperature (130 to 110 ° C.) and low temperature (100 to 110 ° C.) are performed.
Combining polishing at 80 ° C) and shirring to finish into high pile. In the obtained pile product, as the fiber of the pile portion, a short pile in which the colored shrinkable fiber is shrinked by the shrinking process after knitting is used in all the fibers of the pile portion.
It is preferable to contain 0 to 98% by weight, preferably 40 to 70% by weight. When the short pile made of the shrinkable fiber is less than 20% by weight or more than 98% by weight,
A sufficient two-layer structure is not expressed.
