Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an antistatic automobile chair upholstery. [Prior Art] As antistatic automobile chair upholstery, there is a known material in which a conductive backing material is laminated on a pile fabric consisting of conductive fiber-containing pile yarn and conductive fiber-containing base yarn. There is (Jitsukai Sho 60-40497).

Conventionally, polyester fiber filament yarn has been considered optimal for the pile yarn for this type of automobile chair upholstery in terms of physical properties such as abrasion resistance and light deterioration resistance, as well as tactile texture. A material that has been given electrical conductivity is used.

[Problem that the invention seeks to solve]

As is well known, carbon fibers are significantly less adhesive than ordinary organic fibers, and are used in the form of long continuous filaments rather than stable fibers to prevent them from slipping off the upholstery. When it is mixed with polyester fiber filament and used for pile yarn, it is black and has no dyeability, and the effective amount used is small, less than 10% by weight of the total pile yarn, making it difficult to use as a pile yarn. Furthermore, due to the difficulty of blending the fibers, the conductive filament yarns made by blending the fibers are expensive, so they are used in sections at regular intervals, and as a result, the carbon plow fibers used are Dust appears as if finely adhered to the surface, making the appearance of the chair upholstery dirty and unsightly.

[Purpose of the invention]

Therefore, an object of the present invention is to obtain an antistatic white wheelchair upholstery made of polyester fiber with a good feel and excellent durability by mixing conductive fiber with polyester fiber without impairing the aesthetic appearance of the pile surface.

[Structure of the invention]

That is, the antistatic automobile chair upholstery 13 according to the present invention is made by laminating a backing material 12 containing a conductive material on the back side of a woven pile fabric 11, each with an interval A of 30 blinds or less. At B, cationic pile series 14 with cation-modified polyester filament yarns as pile yarns and non-cationic pile series 15 with cation-unmodified polyester filament yarns as pile yarns are arranged alternately. Charcoal rAu for some or all of the pile yarns in pile series 14! 5 to 50% by weight of conductive fibers 16 such as 4 fibers and stainless steel fibers are mixed.
The mixed conductive fibers 16 are cationic pile series l
4 and the non-cationic pile series 15 together account for 0.5 to 10% by weight of the total pile, and the alternating interval G of the conductive pile series 17 of the cation-modified polyester filament yarn having the conductive fibers 16 is 30 ta or less. It is characterized by certain things.

Although the ground structure of a pile fabric is formed from ground yarns other than pile yarns, conductive fibers can also be used in combination with the ground yarns.

Here, "woven" means that the pile fabric may be woven or knitted. In addition, "mixing the conductive fibers 16 in a part of the cationic pile series l4" means that the conductive fibers 16 are mixed in a part of the cationic pile series l4.
When the fiber is composed of several pile series, some of the pile yarns are mixed, and a large number of cationic pile series 14, which are repeated at intervals B by non-cationic pile series 15, are mixed. 14”・14”・・・・・・
Some pile series 14 (or 141,
Or, it means that it is mixed with the pile yarn of 14"...
When the fibers are mixed in some of the pile yarns of one cationic pile series 14, the width of the cationic pile series 14 is equally divided by the conductive pile series 17 that it contains. Multiple repeated cation pile series 14
・14g・l4''...... When discussing some pile series of 14° pile yarn, use a conductive pile series in which the cationic pile series contains conductive fibers 16. It is preferable to arrange the cationic pile series 17 and the cationic pile series that do not contain conductive fibers alternately.
Each width with the pile series 15 is such that their spacing ^ and B are 3
If the width is 0 mm or less, the width can be changed for each pile series.

In that case, the area ratio of the cationic pile series 14 to the entire pile surface should be 50% or less, preferably 20% or less, and the remaining 50% or more, preferably 80% or more, should be the non-cationic pile series 15. When the pile fabric 11 is to be machined with a warp ma, the reed guide is moved in the width direction (horizontal direction), and the cation... pile series 1
4 and the non-cationic pile series 15 should preferably appear on the pile surface in a fine checkered pattern or marbling pattern. [Effects of the Invention] The modified polyester filament yarn that has been modified to have cationic properties is dyed more deeply than the ordinary polyester filament yarn that has not been modified to have cationic properties. Therefore, in the chair upholstery 13 according to the present invention, the cationic pile series 14 are dyed in a darker color than the non-cationic pile series 15 during the dyeing process, and the conductive fibers 16 are dyed in different shades in that way. It is camouflaged by the ground pattern of the cationic pile series 14 and the non-cationic pile series 15 which are interposed in the dark-colored cationic pile series 14 in the pile and alternate with a spacing of 30 cm or less. In this way, the cationic pile series 14 is commonly used to camouflage a small amount of conductive fibers 16 that look like black, dusty birch. This should account for 5 to 20% of the total amount. Due to the camouflage effect of the cationic pile series 14, the conductive fibers 16 have a concentration of 50% by weight in one pile yarn.
Even if it is used in a very limited area where it is less than 10% by weight, it will not be noticeable from the pile surface and the entire pile surface will be beautifully dyed, and it will be interposed at intervals like this. Therefore, the entire pile surface should be made resistant to static electricity. In addition, non-cationically modified ordinary polyester fibers commonly used for automobile chair upholstery are other synthetic Fs. It is difficult to dye the fibers in a darker color than the fibers, and in order to dye the fibers in a darker color, a treatment such as coating the fiber surface with a resin with a low refractive index such as a fluororesin is required. In this case, the conductive fibers 14, which exhibit a black color together with the cation-modified polyester fibers that are dyed deeply, are uniformly dispersed over the entire pile surface, so the entire pile surface has a deep color and is excellent in durability. It is possible to obtain antistatic automobile chair upholstery as a polyester fiber product with a good texture.
