Description

Manufacturing method of the fabric {METHOD OF PREPARING FABRIC}

[Industrial use]

The present invention relates to a fabrication method, and more particularly, to a fabrication method capable of adjusting the transmittance of the desired brightness by resin coating directly on the yarn.

[Prior art]

Polyester fibers are excellent in elasticity, poorly wrinkled, have a lot of excellent properties of shape retention and high strength, and because of these properties, they are widely used as garment fibers.

These polyester fibers are generally used by resin processing, and polyester fiber resin processing is made of polyester fiber to prepare a fabric through a regular (vertical), weaving (weaving) process, and polyvinyl chloride The entire fabric is coated by laminating such films. However, after manufacturing the fabric in this way, when the resin coating is applied, it is not possible to control the amount of light transmission, and in order to express the pattern can not be expressed when weaving, the color can be put in the resin coating can be printed only to express the pattern This makes it difficult to express delicate and sophisticated patterns.

In order to solve this problem, there have been attempts to coat the glass or polyester fiber itself, but in this case, the coating is not good, and a good quality coating yarn of a uniformly rounded state is not obtained, and a flat coating yarn is obtained, so that the actual application is not possible. A thread of impossible quality was obtained.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for producing a fabric which can apply a resin coating to the yarn itself to produce a high quality glass or polyester fabric.

In order to achieve the above object, the present invention is coated with a coating composition comprising a polymeric resin, a phthalic acid or adipic acid-based plasticizer and a flame retardant on the warp fiber and the stomach fiber; Winding and mirroring the coated warp fibers; Weaving the regular warp fibers and the weft fibers; It provides a method for producing a fabric comprising the step of tenting the woven product.

Hereinafter, the present invention will be described in more detail.

TECHNICAL FIELD This invention relates to the method of manufacturing a high quality yarn by giving resin processing directly to a yarn.

In the production method of the present invention, first, the warp (vertical yarn) fibers and the weft yarn (garden yarn) fibers are coated with a coating composition containing a polymer resin, a phthalic acid or adipic acid plasticizer, and a flame retardant.

As the polymer resin, polyvinyl chloride, polyurethane, polyethylene or polyolefin may be used. When using the polyvinyl chloride resin, it is preferable to use a polymerization degree of 800 to 3000. When the degree of polymerization of the polyvinyl chloride resin is greater than 3000, heat resistance or aging resistance is increased, but workability is decreased, and as the polyvinyl chloride coating temperature is increased, the operation becomes difficult. In addition, when the degree of polymerization is lower than 800, workability and surface are improved, but heat resistance and weather resistance are poor.

In addition, when using the polyethylene resin, both linear low density polyethylene (LLDP), low density polyethylene (LDPE), high density polyethylene (HDPE) can be used. The plasticizer may be a phthalic acid plasticizer or an adipic acid plasticizer, and the phthalic acid plasticizer may be dioctyl phthalate, dibutyl phthalate, dimethyl phthalate, diethyl phthalate, diheptyl phthalate, dinonyl phthalate, diisodecyl phthalate, di- Undecyl phthalate, ditridecyl phthalate, butylbenzyl phthalate, butyllauryl phthalate or a mixture thereof may be used, and the amount of the phthalic acid-based plasticizer is preferably 15 to 60 parts by weight per 100 parts by weight of the polymer resin, and 30 to 50 The weight part is more preferable.

As the adipic acid-based plasticizer, dioctyl adipate, diisononyl adipate, diisodecyl adipate, or a mixture thereof may be used, and the amount of the adipic acid plasticizer is preferably 15 to 60 parts by weight per 100 parts by weight of the polymer resin. 50 weight part is more preferable. If the amount of the adipic acid-based plasticizer exceeds 60 parts by weight per 100 parts by weight of the polymer resin, the flame retardancy is poor. The performance is poor, and if the amount is less than 15 parts by weight, the product is too hard and the elongation is not good. have.

As the flame retardant used, an inorganic flame retardant or a halogen-based and phosphorus-based flame retardant may be used. The inorganic flame retardant may include one or more mixtures of magnesium hydroxide, aluminum hydroxide, antimony trioxide, or a mixture thereof. The furnace uses chlorinated organic polyphosphate of tris (2,4-dichloropropyl) phosphate, tris (2-chloropropyl) phosphate, tris (2-chloroethyl) phosphate, chlorinated polyphosphate or mixtures thereof, 3-100 weight part is preferable per 100 weight part of silver polymer resin, More preferably, it is 10-30 weight part. If the amount of the flame retardant is less than 3 parts by weight per 100 parts by weight of the polymer resin, the flame retardancy is inferior, and if it is greater than 100 parts by weight, the cold resistance is poor and the workability is poor, which is not preferable.

In addition, additives generally used in the preparation of polyester fibers, such as azo, cyanine, and imidazole antibacterial agents, may be further added to the coating composition. Since this is well known in the art, detailed description thereof will be omitted.

The coating process is carried out at 130 ℃ to 190 ℃. If the temperature of the coating process is less than 130 ℃ rough surface of the coating yarn, if it exceeds 190 ℃ yellowing phenomenon and concentricity is not maintained is not preferable.

The coated warp fibers are wound and polished. A winding process means the process of preparing an inclination to perform a regular process. The canon process refers to a process of winding an inclined (vertical thread) to a beam to match the length, density, width, etc. of a designed fabric in a fabric manufacturing process, and to wind the work by the desired number of strands and a desired length as needed. it means.

Weaving the warp inclined fibers and the coated weft fibers. The weaving process refers to a process of weaving the weft yarns at a right angle to the warp by crossing each other up and down every one or two warps according to a predetermined rule. In this process, a desired pattern can be expressed. That is, in the conventional process, since the film is laminated after manufacturing the fabric, there is a disadvantage in that the pattern is hardly shown in the process of performing the laminating process even if weaving according to the desired pattern. none.

The woven product is tentered to produce a fabric. Tenta process is a process of finishing the fabric, that is, the process of finishing the fabric.It is a process to fix the width of the fabric uniformly using a tenter. It refers to a process of raising the temperature of the tenter to about 180 to about 200 ° C and fixing it in a situation of maintaining a constant width. That is, this step is a step of fixing the woven product by applying heat to fix it, and refers to an operation for pasting in order to prevent the thread from being pushed.

After the weaving process, a dough screening process of inspecting and washing the product woven before the tenter process may be further performed.

Since the manufacturing method of the present invention is directly coated on the yarn, it is possible to produce the product by adjusting the light transmittance of the desired brightness, and the coated state of the single strand of the coated yarn can be rounded to produce a high-quality product, and the winding process of the weft is performed. There is no need to do so the process is simple. Fabrics can be used for a variety of applications, such as office roll blinds, shades of open air cafes, beach chairs.

Preferred examples and comparative examples of the present invention are described. However, the following examples are only one preferred embodiment of the present invention and the present invention is not limited to the following examples.

(Example 1)

Polyester fibers were coated at 170 ° C. with the coating composition. The coating composition was added to 62% by weight of polyvinyl chloride resin having a degree of polymerization of 1,000, and 26% by weight of diisodecyl phthalate as a phthalic plasticizer and 2% by weight of aluminum hydroxide as an inorganic flame retardant, and an additive of an azo colorant and an imidazole antibacterial agent. It was prepared by adding 10% by weight.

The coated polyester fibers were wound and polished, weaved and subjected to a dough screening process, followed by a tenter process of applying a heat of 180 ° C. to prepare a polyester coated fabric. The weaving process was carried out so that the thread crossing was denser.

(Example 2)

The weaving process was carried out in the same manner as in Example 1 except that the yarn crossing was somewhat loosened.

Various kinds of colorants were changed in the above process to prepare polyester coated fabrics of various colors, and the results are shown in FIGS. 1 to 4, respectively. As shown in Figures 1 to 4, it is possible to produce a fabric having a variety of patterns according to the process of the embodiment of the present invention. In addition, the results of preparing fibers showing two colors using various kinds of colorants are shown in FIGS. 5 to 7, respectively. 5-7, the process of the present invention, which was not possible with conventional processes, can produce fibers that exhibit two colors.

In addition, as a result of measuring the porosity of the polyester coating fabrics commercially available in Examples 1 and 2, Example 1 was a porosity of 0%, Example 2 was 5.5%, the porosity of the conventional polyester coating fabric is 0%. That is, the process of the present invention is carried out before the process of weaving the fabric, so that the porosity can be adjusted according to the consumer's desire, but the conventional process is not able to adjust the porosity by attaching the coating film after the weaving process. It can be seen.

As described above, the production method of the present invention can be applied to the resin coating on the yarn itself, it is possible to adjust the transmittance of light of the desired brightness, to produce a fabric with a uniform resin coating can be produced high-quality products In addition, the desired pattern can be expressed in various colors and shapes during fabric production, and the process is simple and economical.
