Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a pile yarn for obtaining flocked products that have high density and excellent cohesiveness and have a large degree of freedom in design with different pile lengths and finenesses.

(Prior art and its problems) Conventionally, products called "fluff processed products" in which short fibers are flocked onto a base material using gravity or electrostatic force via an adhesive have been used for various purposes. Many of them are short (1 to 2 Il
It was a fabricated product with a 1m thick flocked uniform pile. If you try to transplant hair with a pile length longer than that, you will not be able to increase the density of the sleeve hair, and you will end up with a lot of pile breakage and pile handling, and the surface quality and touch will be poor. .

In addition, the present inventors have already succeeded in manufacturing a high-density flocked fabric using composite 11 fibers with a m degree of 20d or less (Special model 1984-446 bow), but at this stage only one unit The human pile has not been considered.

(Objective of the Invention) An object of the present invention is to obtain a flocked product having a high density (long pile) and to provide a pile yarn that can be flocked all at once with varying fineness.

According to the present invention, not only the fineness can be varied, but also flock processing with an extremely high degree of freedom can be achieved, ranging from long piles unimaginable with conventional V techniques to short piles.

According to the pile raw yarn for flocking of the present invention, from the appearance and touch of lamb's fur with extremely soft feel and excellent cohesiveness to the fur of fox or mink, which has both rigidity and soft feel. It is possible to freely and stably supply a wide range of products, even those with different textures, and is characterized by no pile breakage or pile shedding.

(Structure of the Invention) (1) A pile yarn for flock processing, characterized in that it is a multifilamentary fiber consisting of cores with a fineness of 0.0001 d or more, and the fiber has a fineness of 30 d or more.

(2) Multi-core [Ill of the cores constituting f is small (both 2
The pile raw yarn for flocking according to claim (1), which is a scale.

(Explanation of I-formation) The l1il applied to the present invention is a fiber in which a plurality of cores are joined, and is not only a sea-island type IIH but also an alt that can be peeled and divided with a plurality of core components exposed on the surface. I can't help it. Such fibers can be produced by mixed spinning, composite spinning, or the like.

However, such mixed or composite fibers usually have a fineness of 206
This is the limit that can be economically produced, and if you try to manufacture a weave with a fineness higher than that, the productivity will drop exponentially and the cost will increase significantly. The reality is that it had never been considered to be manufactured, and it had never been put into practical use. The present inventors broke away from the conventional concept of sagging and adopted semi-thick fibers.

Fibers that can be peeled and split tend to have a flat cross-section, and the texture of the raised fluff after flocking tends to be less soft than that of sea-island type gA chicks, but in the present invention, these composite forms It is also possible to mix and use 1llffl with different cross-sectional shapes, and in that case, an excellent flocked product with a mixture of downy hair-like raised hair and prickly-like raised hair is formed. Moreover, in the case of mixed type IIH, a flocked product with random fineness can be obtained.

Such a mixture or composite! The core in the tlile may include, but is not limited to, poly-acepurate, polyamide, polyacrylic, and 1,l' Iff-forming polymers made of boria thereof.

In particular, if the core has an irregular cross-sectional shape, it is possible to provide piles with different luster and touch, and even piles with rigidity. For example, a cross-sectional shape having at least one ridgeline in the direction of the fiber axis has excellent performance and provides a desirable prickly-like nap.

Furthermore, the pile yarn of the present invention can simultaneously contain multiple types of cores, for example, components different in material, fineness, cross-sectional shape, etc. For example, around a core with a relatively large fineness, for example, exceeding 3d, there is a core with a relatively small fineness.
For example o, oo.

By forming a multi-core IM in which cores of 1 to 3 d are arranged and using this as a pile yarn, flocked products consisting of downy hair and prickly hair can be manufactured all at once. Various types of raised products can be constructed as required.

As the sea component for such a core, a polymer is selected which is more easily soluble (easily broken) in solvents (impact) than the core and is in a combination usually applied to such composite fibers.

For example, when the core is polyester, copolyesters, such as copolyesters containing isophthalic acid, especially sodium 5-sulfoisophthalate (solvent: aqueous alkaline solution, especially caustic soda), polystyrene (solvent: genated hydrocarbons, such as trichlene) , nylon 6 (solvent:
Formic acid) and the like can be exemplified, but there is no need to limit it to these.

The pile yarn of the present invention is characterized in that it is very thick with a tlm of 30 d or more, preferably 50 d or more, more preferably 806 or more, still more preferably 100 d or more.

By making the fineness extremely thick, piles with various thicknesses and lengths can be laid for the first time, and the degree of freedom on the 89if of flocked products is great, and the flocking density and bundling properties are improved. Not only can the pile length be short, but even if the pile length is 3 cm or more, or even 5 cm or more, there is no problem with flight performance (and there is no problem with pile breakage). It was able to demonstrate its characteristic of having no piles.

Such extra-thick multifilament tJA14t can be spun using a known method with a large 81 degree comb, but since there are problems such as spinnability, the composite m degree is 2 to 20 (IPi
! Bundle and pack multiple multifilamentary fibers of i to 306
It is extremely convenient to do the above.

Packing here means that the multifilamentary fiber bundles are fixed and integrated by bonding, adhesion, pressure bonding, coating, or the like. However, what is important for such a pack is that it can withstand subsequent cutting and electrodeposition treatment, and that it can be easily removed after hair transplantation.

Any method of integration may be used as long as it satisfies item (1), but examples of item (a) include heating above the melting point of the sea component, applying a sea component solvent, and having adhesive properties. Examples include a method of applying a substance, a method of applying pressure using a roll or frame, a method of covering W1 with a soluble film, and a method of a combination thereof. In addition to ordinary adhesives that satisfy the above conditions, the material that determines the adhesive fl may be anything such as printing paste, various polymers, etc., as long as it has a bone quality of 1q when fiber bundles are combined by drying. do. Among them, the multi-core lli
Preferably, the material is the same as or of the same quality as the polymer constituting the miscellaneous component.

Multi-core I! The IJi degree of the core contained in the miscellaneous material is extremely important as it determines the quality of the flocked hair.

When such a core is made of a pile fiber having a small fineness, for example, 3d or less, a flocked product with an extremely soft feel and a lamb's fur feel can be obtained. In this case, depending on the desired hair quality, the core fiber length should be approximately 0.1 to 3
．． 0d1, and more preferably about 0.5 to 3.0 (l).

In addition, when using pile yarn composed of cores with different fineness,
To provide a flock product having, for example, a fox, marten, or mink appearance, having both downy hair-like raised hair and prickly-like raised hair. In this case, the core fineness of the core constituting the stinging hair is 10 d.
Above, preferably 20 d or more, further 30 d or more can be adopted. Usually, the maximum fineness of the stinging bristles is about 75 to 100 (tcI), which is preferably selected in relation to the performance of downy hair.

The core of Tatsumi girα is constructed in one raw yarn by using a multifilamentary fiber having a core with a prickly texture in the central part of the pile, and a multicore fiber with a core with a downy texture in the surrounding area. Although it is normal to arrange a vAN, there is no need to be particular about this. In addition, if it is desired that the luster, touch, impact resilience, etc. be more prickly, it is preferable to use a core having an irregular cross-sectional shape. Among these, cores having a cross-sectional shape having at least one ridgeline in the direction of the fiber axis, a flat cross-sectional shape, or a combination of these are preferred. Furthermore, as a polymer that makes up the core,
For example, by using a polymer material, such as polybutylene terephthalate or nylon 66, which is generally said to have high impact resilience, raised naps with excellent rigidity can be obtained.

Such pile fibers are cut into appropriate lengths to form piles before being subjected to flocking treatment, and one of the features of the present invention is that the pile shape can be freely selected. For example 1
Even if the pile is as short as ~2mm, it will be 3~201IllI1
Even long piles as described above can be stably transplanted without any problems with flight. The length of the pile can also be set longer in proportion to the fineness of the pile. but,
If it is too long, the pile may break.

(Effect of the invention) According to the pile raw yarn for fabric processing, it is possible to achieve 9 fibers with high density and excellent cohesiveness, and the fineness and type of pile can be set over a wide range, reducing pile shedding. It has the advantage of being able to provide a raised product with an extremely high degree of freedom in terms of elasticity, appearance, and feel without causing any pile breakage or pile breakage, and in particular, being able to stably provide a product that has a natural appearance.

The present invention will be further explained below with reference to Examples.
