Abstract

PURPOSE:To obtain the subject woven fabric, capable of preventing retention and discharge of static electricity and removing damage by static electricity, by arranging electrically conductive yarns in part of pile yarns in a pile fabric at a suitable interval, weaving a fabric, permeating an electrically conductive coating material from the back side of fuzz base parts and forming an electrically conductive layer. CONSTITUTION:Pile yarns 6' prepared by intertwisting electrically conductive fiber yarns 7 in part of pile yarns 6 consisting of, e.g., electrically nonconductive yarns 7, at a suitable interval (interval readily initiating discharge) to weave a pile fabric. A coating material (e.g., synthetic rubber or vinyl chloride) obtained by kneading an electrically conductive material 4 is then permeated and applied to fuzz parts 8 of the pile yarns 6 and 6' to form an electrically conductive layer 5. An earthing terminal 10, as necessary, is mounted between the above-mentioned electrically conductive layer 5 and a base fabric 3. The back side of the afore-mentioned base fabric is then coated with the electrically nonconductive material to afford the aimed antistatic pile fabric. Since discharge is readily initiated and retention and discharge of static electricity can be prevented, the fabric is suitable as sheet covers in automobiles, floor coverings in computer rooms, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the Invention (a) Prior Art and Problems Pile fabrics are used for a wide variety of purposes in daily life environments. The pile fabrics include pile fabrics, pile knit fabrics, tufted fabrics made by flocking, etc., depending on the manufacturing method.

When using any of these napped fabrics in daily life, static electricity is generated due to friction between the fabric and other parts, and depending on the purpose of the fabric, it may be necessary to prevent or eliminate static electricity. Even if the generation of static electricity is not particularly abhorrent, the discharge of accumulated static electricity is never pleasant in daily life. Examples include computer rooms, inside cars, dry rooms, dry regions, other places where static electricity is likely to be generated, and places where static electricity should not be generated. Conventionally, therefore, in order to prevent the accumulation and discharge of static electricity, methods such as spraying a dispersing agent such as water-absorbing resin oil have been used. However, due to the nature of static electricity, this means is not very effective in dry seasons or areas, and there is a problem in that it is not effective for spraying in rooms that require drying.

(b) Problems to be solved by the present invention In view of the above, the present invention solves problems that occur in pile fabrics in living environments where pile fabrics are used, regardless of climate, region, or room location. The purpose is to quickly discharge static electricity, prevent electricity buildup, and eliminate damage caused by static electricity. Therefore, the applicant has previously provided a static-eliminating pile fabric in Utility Application No. 62-26277, but since the life of textiles is to maintain their wind, we have further improved the static-eliminating properties, and also improved the fabric's air-shape retention and the pile yarn. It is an object of the present invention to provide a static-eliminating pile fabric that is effective in preventing lodging.

(2) Regarding the structure of the invention Next, the configuration of the present invention will be described.

The drawings show examples, and FIG. 1 is an explanatory plan view thereof, and FIG. 2 (AXB) is an explanatory cross-sectional view taken along line A-A in FIG. When knitting, whether it is a patterned fabric or a non-patterned fabric, according to the present invention, part of the pile yarn (6') in the pile yarn (6),
Pile yarn (6) made of ordinary non-conductive fiber yarn, such as pile yarn (6') twisted with conductive fiber yarn (7) or pile yarn (6') spliced with conductive fiber yarn (7). Pile yarn (6″) with conductive fiber yarn (7) arranged thereon, or even conductive fiber yarn (7) alone as pile yarn (6″).
') are arranged at appropriate intervals in the woven cloth to weave a pile fabric, and in the finishing process, a coating material such as synthetic rubber, synthetic resin, vinyl chloride, etc. A conductive material (4) is kneaded into the base fabric (3) to form a conductive coating material, and the conductive coating material is permeated from the back side of the base fabric (3) to the raised base (8) of the pile yarn (6) (6'). Conductive layer (5)
is formed, and then a non-conductive coating material (9) such as synthetic rubber or vinyl chloride is coated on the back side of the base fabric. (10) is a ground terminal and the conductive layer (5
) and the base fabric (3).

Depending on the purpose and place of use of the pile fabric, it may not be necessary to coat it with the non-conductive coating material (9), and sufficient strength and discharge properties of the fabric may be ensured without the need for the earth terminal (10). be.

Ordinary pile yarn consisting of raised non-conductive fiber yarn (
6) Any interval is sufficient as long as it can immediately collect the static electricity generated.

(3) Regarding the operation and effects of the invention Since the present invention has the above-described configuration, no matter how wide or narrow the fabric is cut according to the purpose of use, the pile with the conductive fiber yarn (7) always remains. Thread (6') or lead? !
! A pile yarn (6') consisting only of fiber yarns is placed in the fabric surface, and a surrounding pile yarn (6') consisting of non-conductive fiber yarns is placed inside the fabric surface.
6), the conductive fiber yarns (7) are arranged like lightning rods, and the pile fabrics are raised at intervals that allow electricity to be collected. The conductive fiber yarn (7) immediately collects electricity and discharges it by itself, or the conductive material (4) is kneaded into it.
Since it is discharged through the coating material (5), static electricity does not accumulate on the fabric. Therefore, when using the static-eliminating pile fabric of the present invention, it is possible to completely eliminate problems caused by static electricity buildup and strong cam discharge.

In addition, the conductive fiber yarn (7) is twisted or spliced with the non-conductive fiber yarn, or is woven by other methods,
It is dehaired during the finishing process and is mixed in the dehaired pile yarn (6') and all the pile yarns in an almost invisible state, so the static electricity generated is Electricity collection and discharge are even more rapid, and the conductive fibers are completely incorporated into other pile yarns, so that the air flow as a textile (fabric), which is the life of the textile fabric, and as a patterned fabric will never occur. It's not a loss.

In addition, since the conductive layer (5) is provided at the base of the pile, electricity can be collected and removed very quickly, and it also has the effect of preventing the pile yarn from collapsing.

Therefore, there are countless places such as car seat covers, chair covers, computer room floor coverings, clothing, chair upholstery, curtain fabrics, wall coverings, etc., where static electricity is likely to generate and accumulate, and places and objects that should be avoided. There is a tremendous amount of utility value,
It also has the great advantage of being free from the inconvenience of spraying antistatic agents as in the past, and since it prevents piles from collapsing, the period of use of pile fabrics is extended, and its airiness is maintained. has advantages.
