Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile-textured knitted fabric such as a tricot, W Russell, or moquette, which is a brushed cloth having a fiber cross-section on its surface.
The present invention relates to a functional fabric which is made of a fiber such as a titanium oxide-containing small-diameter fiber having an excellent antifouling performance, thereby enabling the surface to have excellent antifouling performance and durability.

[0002]

2. Description of the Related Art Conventional pile-toned knitted fabrics for automobile seats do not take into account the fiber structure used in the raised portion that is mainly soiled (where a dirt component adheres) from the viewpoint of antifouling. For this reason, a high-brightness and high-saturation cloth having a lightness L * of more than 50 has a problem in that dust and sebum are very noticeable to be darkened by a dirt component adhered to the raised portion, thereby lowering the marketability.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a high-brightness knitted fabric such as tricot, W Russell, and moquette in which the lightness L * exceeds 50. For high-saturated fabrics, we provide a fabric with improved antifouling performance with improved durability by composing the brushed yarn with fine-diameter fibers containing titanium oxide that has an excellent antifouling performance factor. Another object of the present invention is to solve the problem of reduced product quality caused by darkening due to dirt.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and comprises a fiber having a fiber diameter of 1.0 to 15.2 [μm]. The average particle diameter obtained by measuring the length is 0.05 to 0.2 [μm]
Is contained in the fiber in an amount of 0.1 to 6 [wt%], and the anionicity of the fiber surface is 0 to -5 at a ζ potential.
An object of the present invention is to provide an antifouling fabric for automobile interior parts which is 0 [mV].

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the contents of the present invention will be described in detail.

The reason why the stain component adheres to the fabric and the darkening is conspicuous is that the stain component adheres to the cross section of the tip of the fiber of the raised portion, thereby increasing the area occupied by the stain component on the surface of the fabric. It is estimated that

The dirt component which turns dark is a black gel-like substance of a mixture of exhaust gas and soot particles and sebum floating in the air, and 30 to 50 [wt] of dust floating in the air.
%], And fine particles of carbon and hydrocarbons caused by exhaust gas and soot are the main generating substances.

First, these fine particles are scattered and deposited on the surface of the fabric, and an external force, such as a frictional force, which causes the human body or clothes to rub dirt on the fabric while sebum adheres thereto. At this time, if the rigidity of the fiber is low, the fiber falls down due to external force, and the dirt component easily adheres to the side portion and hardly adheres to the tip portion, and is excellent in antifouling performance, but when the rigidity of the fiber is high, Is hard to fall down even when an external force is applied, and the dirt component adheres to the cross section of the fiber tip, and the amount of adhesion increases with the elapse of time, and the dirt becomes conspicuous.

The smaller the cross-sectional area of the fiber tip is, the smaller the size of the dirt component that adheres is limited and the harder it is to adhere. However, if the cross-sectional area is large, the dirt components of various sizes tend to adhere and the antifouling performance is improved. Will be inferior.

As described above, conventionally, when a high-brightness and high-saturation cloth having a lightness of L * 50 or more is used as an automobile seat cloth, the antifouling performance is low and blackened dirt cannot be conspicuously used in a short time.

Based on these mechanisms, claim 1
As described in the above, first, the fabric has a fiber diameter of 1.0
It is necessary to consist of fibers of 〜15.2 [μm].

A fiber having a fiber diameter of less than 1.0 [μm] is not preferable because even if no external force or the like is applied, the hair may fall down and the fabric becomes unsuitable for practical use. If the fiber diameter exceeds 15.2 [μm], the stain adhered by the above mechanism becomes conspicuous during use, and the antifouling performance decreases. More desirably, the fiber diameter is 8 to 12 [μm].

Next, the average particle diameter obtained by measuring the major axis length and the minor axis length of the particles by electron microscopy is 0.05 to
0.2 to 0.2 μm of solid powder in the fiber
[Wt%] must be contained. Here, electron microscopy refers to observing solid powder particles using, for example, a scanning electron microscope (SEM) and measuring dimensions such as a major axis length and a minor axis length.

The major axis length of a particle refers to the length of the longest part of the linear distance from one end to the other end through the center of one particle, and the minor axis length is the major axis length. Taking the axis perpendicular to the length, the shortest axial length is the linear distance from one end of the particle to the other. The length obtained by adding the major axis length and the minor axis length thus obtained and dividing by 2 is the average particle diameter.

Titanium oxide is an example of the solid powder material, and PET fiber is an example of fiber type. The surface of the titanium oxide-containing PET fiber is smoothed with an increase in the titanium oxide content. The cross section is smoother than a normal PET fiber cross section. This effect has a cross-sectional shape that makes it difficult for dust and sebum to adhere to clothes due to abrasion, and thus has the effect of reducing the adhesion of dirt. Further, there is an effect that dirt attached to the fiber is made inconspicuous by a soil hide effect due to light scattering of titanium oxide.

At this time, the average particle diameter of the solid powder is 0.05
To 0.2 [μm], and the particle diameter is 0.1 μm.
If it exceeds 2 [μm], the fibers become brittle, and the actual use durability is extremely poor. The particle diameter is 0.05 [μm]
If it is less than 1, it is not preferable because it is not uniformly dispersed in the fiber raw material and the quality is reduced. More desirably, the particle size is 0.1.
09 to 0.11 [μm].

If the content of the solid powder is too large, the fibers may become brittle and the durability performance such as abrasion may be degraded. In order to reduce the abrasion and friction with the fiber, the content of the solid powder in the fiber must be suppressed to 6 [wt%] or less. Further, at least 0.1 [wt%] for smoothing the fiber surface.
Must be included. More preferably, the content is 2.
It is 5 to 3.5 [wt%]. Further, it is necessary that the anionicity of the fiber surface of the fabric is 0 to -50 [mV] in ζ potential.

As described in the stain adhesion mechanism described above, the dark stain is one component of sebum, and the present invention is focused on the fact that the sebum tends to be negatively charged. By imparting an anionic property to the surface of the fiber, the fiber surface is negatively charged and has an effect of electrically repelling the sebum of the dirt component to reduce dirt adhesion.

In order to impart an anionic property to the fiber surface, for example, there is a cation die (CD) treatment method. The cation dye (CD) treatment method is, for example, to copolymerize 5-sulfosodium isophthalic acid with a fiber material, thereby imparting an anionic property to the fiber surface to make the fiber surface negatively charged, thereby reducing the sebum of the dirt component and electricity. It is intended to exert an effect of reducing the adhesion of dirt by repulsion.

At this time, if the anionic property of the surface of the fiber constituting the fabric of the present invention is greater than 0 [mV] at ζ potential, the effect of preventing sebum component adhesion is undesirably lost. Also-
If it is less than 50 [mV], of the dust in the air, the negatively charged one is further sucked, and consequently, the dust is easily stained, thereby deteriorating the antifouling performance. More desirably, the ζ potential is −35 to −45 [mV]. As a method of measuring the ζ potential, for example, there is a method of measuring the potential difference between the surface of one fiber and the air using a potentiometer.

Next, as described in claim 2, the solid powder is a rutile-type or anatase-type titanium oxide,
It is a solid powder of a material selected from the group consisting of alumina, calcium carbonate, magnesium carbonate, barium sulfate, and calcium sulfate, and must be made of a fiber containing at least one of these solid powders.

The effect of titanium oxide as an example of the solid powder material has been described above, and the effect and action are any of rutile-type or anatase-type titanium oxide, alumina, calcium carbonate, magnesium carbonate, barium sulfate, and calcium sulfate. The same applies to the case where at least one is used.

The fabric of the present invention is also characterized in that the basis weight is 150 to 650 [g / m ² ]. The basis weight is 150 [g / m ² ]
If the diameter is smaller, the abrasion endurance performance is deteriorated, and wear and tear are generated, which is not preferable. In addition, the basis weight is 65
If it exceeds 0 [g / m ² ], the workability will be affected, and it will be difficult to stretch the fabric over parts such as sheets. Also, for example, the fabric area used per vehicle is 10 to 15
[M ² ], which is not preferable because it causes excess weight. More preferably, the basis weight is 400 to 500 [g / m ² ].

The fabric of the present invention is also a pile-textured knitted fabric according to claim 4, wherein the length of the raised portion is 0.9.
２2.6 [mm]. If the thread length of the raised portion is shorter than 0.9 [mm], the wear durability is reduced as in the case where the basis weight is reduced, and undesirably fraying occurs. The yarn length is 2.6 [m
m], hair fall on the surface of the fabric is apt to occur, which is not preferable because it lowers the appearance and the commercial value. More preferably, the yarn length is 1.5 to 2.0 [mm].

Further, the fabric according to the present invention is characterized in that the fabric is a knitted pile fabric. Pile-toned knitted fabrics such as tricot, W Russell, and moquette have a smooth feel due to the brushed surface.For example, when used for automobiles, etc. It is very effective.

Finally, the fabric of the present invention is a vehicle seat, a door trim, a pillar garnish, a head lining, an instrument panel, a glove box, a console, a console box lid, a steering wheel, a shift as described in claim 6. A fabric for a lever, around a sunroof, a sun visor, an assist grip, and a parcel shelf, wherein a fiber constituting the fabric is any one of polyester fiber, polyamide fiber, acrylic fiber, fluororesin fiber, and polypropylene fiber.

The above-mentioned automobile parts and parts are often provided with a fabric on the outside surface inside the vehicle cabin in order to secure their commerciality. In addition, there are many opportunities for the human body to come into contact with these parts and components, and it is expected that dirt due to sebum is likely to occur. Therefore, by using the product of the present invention for these parts and components, the antifouling performance is improved, and it is possible to secure the commerciality even when using high-brightness and high-saturation fabrics in which dirt is particularly conspicuous.

The fibers constituting the fabric are polyester fibers, polyamide fibers, acrylic fibers, fluororesin fibers,
Desirably, any of polypropylene fibers.
This is because these fibers are artificially synthesized, have stable mechanical properties such as strength, have small variations in quality, and can stably secure a supply amount.

The cross-sectional shape of the fiber used in the product of the present invention is not particularly limited. However, a fiber having a round cross-section or an elliptic cross-section having an aspect ratio of 1 to 1.5 has a small unevenness on its side surface, for example, a dirt component is caught and adhered. Such physical adhesion is less than that of irregular cross-section fibers such as star-shaped cross section, three-lobed cross-section fiber, and flat cross-section fiber whose flattening rate is even larger, with a large unevenness on the fiber side area. Alternatively, an elliptic cross section having a flatness of 1 to 1.5 is desirable.

Hereinafter, examples of the present invention will be described in detail together with comparative examples, but the present invention is not limited to only the examples described here.
