Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a novel synthetic resin-coated fiber produced by the present inventor as a raw material to produce a coarsely woven fabric,
This invention relates to a method for producing a synthetic resin-coated fiber fabric by weaving synthetic resin-coated fibers that are highly breathable, strong, weather resistant, and stain resistant by fusion-bonding the intersection points of each raw yarn. .

Among conventional textiles coated with synthetic resin, those that start from textiles and are coated with synthetic resin have the disadvantage that they are not breathable and cannot be used in fields that require breathability. Fabrics woven using synthetic resin-coated fiber bundles manufactured through bathing as raw materials have the strength and elongation of the raw fiber bundles,
The strength of the fabric is reduced due to loss of elasticity and flexibility.
It has poor durability, cannot be used in high-load applications under harsh conditions, has limited uses, and has the disadvantage of impairing the feel of a textile. In view of the above, the present invention is woven using fiber bundles coated only on the surface with a new synthetic resin produced by the invention of the present inventor, who also applied for a patent at the same time, and by melting and joining the intersections of each raw material yarn. It is highly breathable,
In addition, both the polyester adhesive and the synthetic resin coated on it coat only the surface of the fiber bundle and do not penetrate between the filaments of the fiber bundle, so the strong and flexible texture of the fabric is not lost. Moreover, the present invention provides a method for producing a synthetic resin-coated fiber fabric that has a beautiful quality and does not shift its weave, and can function satisfactorily even under harsh conditions in the field of general industrial materials.

The synthetic resin-coated fiber bundle used in the present invention is produced by passing the fiber bundle 2 through a solid hot-melt type powder polyester adhesive bath 3 at room temperature and adhering it to the fiber bundle as a solid powder, as shown in Fig. 1. and then turn it into an extruder (Extrud).
er) 4, and first heated to uniformly fuse the solid powder adhesive to the surface of the fiber bundle, and then treated the outer surface with a molten synthetic resin having a higher melting point than the polyester adhesive to form a molten synthetic resin. However, only the surface of the fiber bundle is coated uniformly and firmly without any infiltration between the filaments inside the fiber bundle, and the fiber bundle is stretched 5 and wound 6 to produce a synthetic resin-coated fiber bundle.

Using this synthetic resin-coated fiber bundle, the number of strokes, for example, 9 ×
It is woven into a coarse woven fabric of 9 strands/inch or 11 strands/inch, etc., and immediately connected to a tenter zone at a temperature of 150~
A synthetic resin-coated fiber fabric is produced by the method of the present invention in which a synthetic resin-coated fiber bundle is attached to each weave by heating and drying at 170°C for about 2 to 2 seconds.

The powdered polyester adhesive that is solid at room temperature used in the present invention is a hot-melt adhesive mainly composed of thermoplastic copolymer polyester.
~125C, 135-150℃ or 160-175℃
PES-120P, 140P, or 170P (all are trade names of hot-melt adhesives manufactured by Toagosei Kagaku Kogyo Co., Ltd.) is preferably used as a compound having a particle size of 1 to 200p and stable at room temperature.

Furthermore, since the adhesive is used in the form of a solid powder, it does not require a solvent, has an effective solid content of 100% at room temperature, is non-toxic, has no risk of ignition, and is free from environmental pollution, and is free from the fibers of the raw yarn. Since a flexible adhesive layer is formed only on the surface of the bundle, there is an advantage that the original texture of the raw fibers is not impaired.

As mentioned above, the raw material synthetic resin-coated fiber bundle used in the present invention is uniformly and firmly coated with the adhesive only on the surface of the fiber bundle, and does not penetrate into the filaments inside the fiber bundle. Fiber bundles have the advantage of retaining the strength, elongation, elasticity, and flexibility of the fibers themselves, and the resulting fabrics have high strength and elongation and flexibility without losing the texture of the raw fibers. , the welder peeling or shearing performance is high, and the intersections of each yarn in the weave are... Since it is fused, there is an advantage that even if the weave is opened by about 2 to 3 α, there is no so-called misalignment of the weave of the fabric, and the quality of the beautiful fabric is maintained.

Furthermore, since the raw material fiber bundles of the woven fabric are coated with synthetic resin, they have excellent weather resistance and stain resistance. As raw material fiber bundles, any natural, artificial, synthetic, or mineral fibers can be used depending on the purpose, but when used in the field of general industrial materials, synthetic fibers such as nylon and polyester, carbon fibers, glass fibers, etc. is suitable.

In addition, as synthetic resins, vinyl chloride resins, acrylic resins, urethane resins, nylon resins, etc., which have a higher melting point than hot-melt type powdered polyester adhesives, are suitable. For example, for applications that require elongation, nylon continuous fibers are used as raw materials. PVC resin is used as the surface synthetic resin, polyester fiber is used as the raw material fiber for applications that require dimensional stability, glass fiber is used for special applications that do not require elongation, and Young's modulus It is preferable to use carbon fibers as raw material fiber bundles for specific applications.

For example, a synthetic resin-coated polyester fiber of 1000 d to 1500 d (denier) is used, and a woven fabric with a stitch count of 11 x 11゛/inch is used for container bags, etc.
The 11 x 11/inch fabric made of nylon can be used as a curing sheet for concrete etc., and can also be used as a curing sheet for concrete etc.
A woven fabric made of 500 d polyester fibers with a stitch count of 9 x 9/inch is suitable for use as a windshield sheet.

In this case, the surface coating synthetic resin is not particularly limited, but vinyl chloride resin is used in the tenter zone after weaving.
The weave is completely fused at temperatures between 15 and 208 degrees Celsius, and even if the weave is open at about 2 to 30 degrees, there is very little thread slippage or misalignment, resulting in a beautiful quality fabric. In addition to the advantages that can be obtained, there are also economical advantages. Next, Table 1 below shows a comparison of only the characteristics of the coated fiber fabric produced according to the present invention and the fabric composed only of fiber bundles. For comparison, a fabric made of the same fiber bundles that is not coated with synthetic resin is shown. In this case, the yarn used is a 1890 denier nylon fiber bundle, with a 100 denier
% vinyl chloride compound coating, the obtained fiber bundle is 67K denier and the amount of synthetic resin coating is 3% to the raw yarn.
It was 56%.

The tensile strength (K9/3a1) of the yarn used is 110k9 in the vertical direction.
Welder shearing, length 80kg, welder peeling, length 37
It is k9. From the results shown in Table 1, it can be seen that the fabric of the present invention has high weather resistance and significantly less shear of the fabric.

Next, as a processing method using nylon and polyester yarns, a synthetic resin-coated fiber fabric manufactured by the method of the present invention and a conventional yarn step (Dip) were used.
Tables 2 and 3 compare the properties of the synthetic resin-coated fiber fabric produced by the method and the conventional dipping method at the textile stage.

However, as for polyester yarn, only the case of the present invention is shown in Table 3 because synthetic resin-coated fiber fabrics manufactured by conventional methods such as those for nylon have not yet been manufactured.
