Abstract

The present invention relates to a method for producing a sewn fabric tape and a sewn fabric tape thereby, comprising forming a sewn fabric sheet using a 50 denier filament serving to make 90 g / m of 4 denier polyester yarn, the sewn fabric Tentering at a temperature between 180 ° C. and 210 ° C., a singing step to remove the debris from the surface of the fabric by transferring the fabric at 400 ° C. to 100 m / min. Calendering the fabric to a pressure of 4 tons at 200 ° C. to have a uniform thickness of 0.33 to 0.48 mm, and coating the coating layer with a material selected from acrylic and urethane to prevent leakage of adhesive on one surface of the fabric thus produced. Forming, comprising the step of applying a conventional rubber-based adhesive on the surface of the coating layer, it is possible to significantly reduce the weight than the conventional tape By reducing the weight of the electrical wiring, which accounts for 5% of the total weight in the car, the weight of the body is ultimately reduced, resulting in improved fuel economy and improved productivity in electrical wiring work with excellent flexibility that is not affected by ambient temperature. In addition, there is a noise reduction effect by absorbing the noise generated in the engine room, especially when used for the binding of the electrical wiring in the engine room of the vehicle.

Woven tape

Description

A method of manufacturing a sewn fabric tape and a sewn fabric tape thereby {A TEXTILE TAPE AND A METHOD OF MANUFACTURING THE TEXTILE TAPE}

       1 is a schematic process diagram for explaining a method of manufacturing a woven fabric tape of the present invention.

FIG. 2 is a schematic diagram of a sewing fabric tape of the present invention manufactured in the process of FIG. 1. FIG.

The present invention relates to a tape manufacturing method, in particular, by applying a pressure-sensitive adhesive to the fabric sewn non-woven fabric of polyester SF yarns, a method of manufacturing a tape fabric having a light weight, excellent flexibility and sound-absorbing properties and the fabric produced by such a method It is about tape.

Tapes are widely used in everyday life and various industrial sites for bonding and fixing objects, and are generally manufactured by applying an adhesive to the surface of a base material of a synthetic film or a synthetic resin having a metal sheet or a reinforcing yarn.                         

However, the conventional synthetic resin tape is sensitive to temperature, there is a difficulty in taping work and brittle in the winter, there is a problem that is deteriorated at high temperatures, and there is an excessive problem of its own weight.

Accordingly, an object of the present invention is to prepare a tape base material with a polyester yarn sewn fabric and to apply a pressure-sensitive adhesive on one surface thereof, and to produce a tape fabric having improved durability at high temperature with excellent flexibility and sound absorption properties at light weight. And a fabric tape produced by such a tape manufacturing method.

In order to achieve the above object, a method of manufacturing a sewn fabric tape according to the present invention, a carding step of forming a fiber fleece by spreading the polyester SF yarn to a certain thickness by blending and blending at least one of the fiber fleece Forming a sheet by laminating two layers to form a lap of a predetermined thickness, wherein a needle punching step of binding at least two fleeces of the lap together so as not to move, and sewing the needle punched lap with thread Tensing step of fixing and drying the width of the sewn sheet at a temperature of 180 ° C. to 210 ° C., and a singing to remove lint by burning with 400 ° C. hot air from the surface of the tented sewn fabric sheet. ), A calendering step of flat pressing the woven fabric sheet at high temperature and high pressure, at either surface of the flat squeezed woven fabric sheet Further comprising: a pressure-sensitive adhesive coating of acrylic, urethane and so on does not leak to the other surface, comprising the step of applying the pressure-sensitive adhesive on the coating layer.

In the production of the sewn fabric sheet according to the present invention, it is preferable that the 4 denier polyester S.F.

The sewn fabric tape according to the present invention is a sewn fabric sheet uniformly enclosed by 50 denier filament serving to be 90 g / m with 4 SF of polyester SF yarn, and acrylic applied to one surface of the sewn fabric sheet to prevent the adhesive from leaking. It comprises a coating layer of a material selected from urethane and an adhesive layer applied to the surface of the coating layer.

The present invention will be described in more detail with reference to the following examples.

1 schematically shows a process for producing a woven tape according to the invention.

It is preferable to use a 4 denier polyester S.F. company as a raw material of a sealing fabric tape so that the sealing fabric sheet produced through a series of processes mentioned later may be 90 g / m.

First, the polyether SF yarn mixture as a raw material is metered by a predetermined amount by the electronic control measuring device 1, and passed through the opener 2 and the blender 3, and then the mixture is placed in the hopper 4 and the carding machine. It is fed to (5) to open and face down and spread to a certain thickness to form a fleece.

The fiber fleece is laminated by at least two layers by a lapping machine 6 to form a lap of a certain thickness, which is bound in the needle punching machine 7 so as not to move the at least two flies of the wrap relative to each other. .                     

Then, in the needle stitching step, the lap punched by the needle punching machine 7 is sewn together with the fleece-bonded wrap with thread in the needle needle 8 to form a sewn fabric sheet as a substrate of the tape. The needle needle is preferably carried out uniformly to serve 50 denier filament.

The encapsulated woven fabric sheet is dried at a temperature of 180 ° C. to 210 ° C., preferably 210 ° C., in the tenter 9 to fix and flatten the width of the sheet, and then to the surface of the tentered woven fabric sheet. There will be lint, which must be removed to facilitate the application of the adhesive in subsequent processes. To this end, while feeding the fabric sheet at a speed of 100 m / min. In a singing machine: 10, hot air at 400 ° C. is supplied to remove the lint on the surface of the fabric sheet.

Pressing the fabric sheet at a pressure of 4 tons at 200 ° C. at a calender 11 to densify the texture of the lint-free fabric sheet and to have a uniform thickness of 0.33-0.48 mm suitable for use as a tape. Thereby, the flattened crimped fabric sheet as a base material of a fabric fabric is completed.

In order to prevent the adhesive from leaking from one surface to the other surface when applying the adhesive, the surface of the fabric sheet is first coated with acrylic, urethane, etc., and then the pressure-sensitive adhesive applicator is applied to the adhesive fabric sheet. In (13), a sealing fabric tape is produced by applying an adhesive to the surface of the coating layer.

As shown in FIG. 2, the fabric tape 20 of the present invention manufactured by the above-described process is encapsulated with the reference numeral 21, and the fabric fabric sheet 20 is coated with acrylic or urethane on its bottom surface. 22) and an adhesive layer 23 on the surface of the coating layer.

The sewn fabric tape according to the present invention is lighter than a tape manufactured by conventional synthetic resins by sealing the at least two layers of fleece from polyester yarns to form a sewn fabric sheet and used as a substrate of the tape, and is not affected by the ambient temperature. Extremely flexible, workability is improved and durable.

The woven tape of the present invention having these characteristics can reduce the weight of the vehicle at a weight lighter than that of the conventional tape, especially when used for fixing electrical wiring, which occupies 5% of the total weight in automobiles, thereby improving the fuel efficiency of the vehicle. It is possible to obtain a good sound absorbing properties, and partially absorbs the noise generated in the vehicle engine room, thereby reducing the noise.
