Abstract

PURPOSE:To obtain a suedelike external appearance with soft touch without cotton dusts by implanting piles B each having specific thickness and cutting length in a specific piling density on the face implanted with piles A each having a specific thickness and cutting length. CONSTITUTION:Piles B each having 0.5 - 3.0 of denier of thickness and 0.3 - 0.7mm of cutting length are implanted in an piling density of 5,000 pieces/cm<2> or more on the face implanted with piles A each having 0.5 - 2.0 denier of thickness and cutting length of the range represented by a formula (1). When the thickness of the pile A is d(denier) and the length of the pile A is L (mm), the formula (1) is 2 X d<1>$u/$X<2> >= L >= 1 X d<1>$u/$X<2>. The piles A are previously implanted, and the piles B having short cutting length are then implanted. Thus, the piles having short cutting length are implanted in necessary number or more to sufficiently cover an adhesive layer with the short pipes in addition to the long piles, thereby obtaining the number of the piles and piling density which can satisfy the physical properties such as wear resistance, etc.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has no adhesion of cotton dust and has good physical properties,
The present invention also relates to a flocked product J>J that has a soft touch and suede-like appearance and has a wide range of uses, and a method for manufacturing the same.

[Conventional technology 1] Recently, when touching the 6th side of the hair transplanted product with your hand,
〜, and the color is deep and has a deep color.There is a growing demand for a 5-erushion that has a 5-color feel, but as a technologically oriented product that meets this request, we are developing J, sea urchin, which can produce thin piles for flocking. As a result, it has become possible to produce flocked products using 1-denier Kamigawa pile.

When the pile becomes thinner, the flocked surface becomes softer to the touch in accordance with the above requirements, but its physical properties, especially mechanical properties, become weaker. The scope of use was limited to non-small businesses.

In addition, flocked hair products have long been known to have the disadvantage of being prone to attracting cotton lint (43), and due to this problem, hair flocked products have only been put to practical use in very limited applications.

[Problems to be Solved by the Invention] The present invention solves the problem of cotton dust, which is present in the above-mentioned conventional flocked products.
In addition to reducing the problem of troughs, we can produce a flocked product that has a suede-like appearance with a soft touch when touched, and has good physical properties. The aim is to significantly expand the range of uses.

[Means for solving and overcoming the problems] This [method of the present invention that meets point 1]! i+'r hair products have a thickness of 0.5 to 2.0 denier and a cut length of 0.5 to 2.0 denier.
) The pile (A) in the range expressed by
~I (is 0.3~0.7. Pile (B) is 000 pieces/cut or more than 7? + Hair density is made of hair.

Here, if the thickness of the pile (A) is ci (denier) and the length of the pile (A") is L-(ai), then formula (1)
is expressed as follows.

2XJ Positive ≧ 1 ≧ 1 This method consists of cutting a short pile (B) with hCl.

The present invention was completed by adopting the following ideas and through analysis of the following problems in the prior art.

First of all, regarding the removal of cotton dust, it is the same as saying that it is easier to remove cotton dust with a glossy brush than with a soft brush. If the pile is hard, the cotton lint will stick to it and cause hair as it is scraped off.Therefore, in order to prevent the lint from sticking and cover it, it is necessary to use the flocked pile like a soft brush. To explain this in terms of the condition of flocked pile, it can be said that the pile cannot stand on its own and the In point of the pile begins to sag at 4F.

The shape of the pile that results in this state is quite different from the conventional idea in hair transplantation. )? For the 11 inch length, if you graft a thin pile at 416 degrees and a flexible pile like this, ill! 3
It becomes possible to satisfy the requirements of the small mountain section, that is, to provide a soft touch and a luxurious suede-like feel.

However, when the pile becomes weak as described above, due to the principle of electrostatic flocking, the pile that is about to be flocked tends to collide with the pile that has already been flocked, resulting in a low flocking density. A decrease in h9 hair density is not preferable from the viewpoint of physical properties of the flocked surface.

In other words, practical flocked products cannot be produced by thinning or lengthening the flocked pile.

This 41? As a result of investigating the relationship between Z hair density jσ and the physical properties of the flocked surface, in particular the abrasion resistance that is observed manually as a physical property of flocked products, it was found that damage to the flocked surface can be reduced by one step up to the adhesive layer that adheres the flocked pile. They discovered that the main cause is hair extension and swelling, and in order to prevent this, it is essential to have more than the required number of piles of the required length, that is, to have the necessary density. .

Therefore, in order to satisfy the abrasion resistance of flocked products, it is necessary to increase the flocking density to a certain level, but in order to reduce the problem of fluff (as mentioned above), it is necessary to increase the flocking density to a certain level. If it is used, it becomes difficult to achieve the above-mentioned predetermined level of flocking density.

The present invention satisfies this seemingly contradictory condition to 11 μm.

As a result of extensive tests, the present inventors found that after transplanting a pile with a good shape and appearance that prevents cotton wool from adhering to it, it was found that By flocking more than the required number of fibers (in addition to long piles) and covering the adhesive layer with zero pile for -1 minute, the wear resistance can be increased to 100%. I discovered that it can be done.

In other words, after transplanting the pile (A>) whose length is 0.5 to 2 denier
~3 denier with a cut length of 0.3~0.
7m pile ([3) with at least 5,000 piles/cm”
By flocking the fibers twice, it is possible to alleviate the above-mentioned problem of fluffing and at the same time overcome the -1 minute abrasion resistance.

In the present invention, if the pile (Δ) that is first flocked is too thin and thick, the physical properties of the pile (A) layer itself will deteriorate, and if it becomes too thick, it will become like a hard brush and attract cotton dust. Therefore, in order to achieve the same strength and softness (W), it is necessary to have a denier of 0.5 to 2 denier.

In addition, the cut length of the pile (A>) needs to be 1≧1xL to avoid the attachment of fluff (), but if it is too short, not only will the flocking density become extremely low, 2×
E must be positive ≧ [-. According to formula (1), the preferred flocking density of the pile (A) is that there should be a gap of 500 mm compared to the pile (B) that is later flocked. Since the specifications are quite far apart, it is sufficient that the hair is coarsely flocked. However, in order to make the physical properties more robust, the full flocking density is 70.
It is more preferable to cover up to 8()%. Short piles of cut barbs (B) to protect the adhesive layer to improve physical properties, which are subsequently flocked, require at least 0.3 # of cut barbs for anchoring, C, and 0.7 If it is larger than #, it is not preferable because you will not be able to obtain enough 41 eight-haired honey melon, and the denier of the pile (13) is less than the pile (A
> is equivalent to y) or the second person is preferable, 0.5~
If it is 3 denier, it is long. The preferable flocking density of the pile ([3) is 5000 wood/CIi or more.

In addition, the above-mentioned cut is a pile (A>
It is also possible to mix the hair and pile ([3) in advance and flock it, but since the long h pile (△) will have the so-called crater defect, you will get 11 mark and 16 flock density. It's difficult. Therefore, it is necessary to cover the pile (A) and the pile (B) separately, and the pile (A)
After the hair transplantation, a pearl (B) is implanted to cover the desired area. A hair transplant product is obtained.

The material of the pile in the present invention is cotton, natural 841i string such as wool, recycled fiber such as rayon, semi-synthetic fiber such as acetate, nylon, delinquent fiber, etc. ,
Synthetic fibers such as acrylic and inorganic fibers such as carbon are also acceptable, and C is not limited to 1).

Swallowing agents
In addition, vinyl acetate, acrylic resin, polyurethane resin, etc. can be used without particular limitation as long as it adheres well to the pile-constituting fibers described above.
