Description

Flame retardant car seat cover {Seat Cover for Car}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to automobile seat covers and, more particularly, to flame retardant automobile seat covers woven using polyester copolymer flame retardant yarns.

Recently, the use of flame retardant fibers is strictly regulated in textile products, children's pajamas, aircraft and car seat covers in public places, and in Korea, the use of flame retardant fabrics is increasing in public facilities such as hotels. As the relevant laws and regulations are strengthened and maintained, the market for flame retardant fibers is expected to expand.

Among them, the automobile seat cover is made of dobby fabric and jacquard fabric, and in order to impart flame retardancy to such fabric, a flame retardant is added to the product by a coating method (post-processing) or chemically bonds a flame retardant material in a polyester yarn (copolymerization). There is a way.

In the former case, flame retardant treatment is performed in a coating process after weaving and salt processing using polyester yarn as a raw material yarn. In other words, after weaving hard and weft yarns using polyester yarns, the flame retardant effect was expressed during salt processing or coating. However, the method of imparting flame retardancy by post-processing has a problem in that flame retardancy is reduced by washing or the like.

In the latter case, which can solve the disadvantages of the former, bromine (Br) compounds or phosphorus (P) compounds are mainly used for flame retardation of polyester fibers by copolymerization. The use of bromine system is regulated and only phosphorus compounds are applied.

On the other hand, when the temperature is high, such as in summer, there is a need for a car seat cover that can smoothly absorb the sweat of the occupants. In order to satisfy such conditions, it is preferable to manufacture a seat cover using a yarn having quick-absorbent quick-drying, but in the past, there was a limit to applying the sweat-absorbent quick-drying yarn as a flame retardant yarn.

For example, in order to increase the sweat-absorbent quick-drying, the cross-section is made in the form of cross, spade, arm, or dumbbell rather than circular to increase the surface area to increase the absorption power, using the conventional copolymer flame retardant yarn described above in the yarn cross section When the spinning work to generate a special cross-section has a problem that the productivity is reduced to about 50-60% because the spinning nozzle of a relatively small diameter of 2Φ was used in the past.

In addition, the vehicle seat cover needs to provide comfort to the occupant by forming a proper volume in addition to the quick drying sweat. In order to form a sense of volume in this way, the three-sum yarn can be applied, but the three-sum yarn is also limited to use as a flame retardant yarn. In other words, the conventional fine-seam yarn spins mono denier at 0.3 to 1 denier, but conventionally, when spun yarn of the above-mentioned range is spun using a flame retardant yarn copolymer, due to the phosphorus (P) component contained in the yarn There was a problem that the radiation yield drops to 40-50%.

Therefore, in the past, it was virtually impossible to manufacture a car seat cover using a quick-drying flame retardant yarn or sesame flame retardant yarn.

The present invention is to solve this problem, by applying a copolymer flame retardant yarn and sesame flame retardant yarn having a sweat-absorbing quick-drying characteristics to prevent the degradation of flame retardancy, and to solve the user's sweat quickly, etc. It is an object to provide a flame retardant automobile seat cover.

Another object of the present invention is to provide various colors to the manufactured car seat cover.

In order to solve the above problems, in the present invention, a polyester copolymer having a density of 80 to 120 bones / inch for warp yarns quick-drying flame retardant yarn or sesame flame retardant yarns, and a polyester having a density of 40 to 120 bones / inch for weft yarns Copolymer absorptive fast drying flame retardant yarn or sesame flame retardant yarn is applied, and a flame retardant automobile seat cover is provided which is woven into an orbital structure in which wefts are alternately engraved on a warp. At this time, in consideration of functionality and features of the car seat, for example, preventing the phenomenon of crushing of the fabric, volume, breathability, etc., it is preferable that the weaving is made of dobby or jacquard double woven (multi-woven).

According to the present invention configured as described above, by spinning a copolymer flame retardant yarn and sesame flame retardant yarn having a sweat-absorbing quick-drying characteristics and then fabricated to the car seat cover to solve the degradation of flame retardancy and the user's sweat quickly It can provide a proper sense of volume to the user.

In addition, it is possible to express a variety of colors by applying a four-step temperature change to the three-sum flame retardant yarn and the sweat-absorbing quick-dry flame retardant yarn, thereby contributing to the enhancement of the seat cover.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a flame retardant vehicle seat cover according to the present invention.

The automobile seat cover of the present invention optimizes the sweat-absorbing quick-drying, voluminous feel, flame retardancy, etc. by selectively using polyester copolymer sweat-absorbing quick-drying flame retardant yarn and polyester copolymer sesame flame-retardant yarn on the warp and weft, the design is weaving with dobby or jacquard The fabric configuration is an eco-friendly seat cover that gives any one of the characteristics of single, double and triple weave.

A cross section of the seat cover thus manufactured is shown in FIG. 1. In this case, a chip having excellent flame retardant performance having an aliphatic compound structure having both hydroxyl groups of the same structure as a telephthalate acid used as a polyester raw material when synthesizing a copolymer for producing a polyester copolymer flame retardant yarn, and a chip In order to manufacture the yarn after drying, the yarn cross section is designed with cross-type, spade type, eight-lobed type, and dumbbell type, so as to make the sweat-absorbing quick-drying performance excellent during weaving. A yarn having a mono denier of 0.3 to 1 denier is produced.

The seat cover of the present invention is woven in the form of dobby or jacquard with an inclined density of 80 to 120 bones / inch, and a weft density of 40 to 120 bones / inch. Yarn protruding from tissue can hinder the fabrication of fabrics made. In this case, the present invention has been described as an example of the double weave for convenience of description, but is not limited thereto, and may be formed as a multi-weave by repeating a single weave or a double weave. However, considering the functionality and features of the car seat, for example, preventing the phenomenon of woven fabrics, volume, breathability, etc., it is better to be woven by jacquard double weave.

Sweat-absorbent quick-drying flame retardant yarn improves flame retardancy by using polyester copolymer yarn of 150 to 300 denier, and forms a loop on the appearance of yarn during processing by using air pressure to increase the bulkiness and flexibility of the yarn. It is a sum of six to six sums. If the sweat-absorbent quick-drying flame retardant yarn is 150 denier or less or 2 or less, the tear strength (resistance to the case of sequential breaking of the yarn) may be lowered, and if it is 300 denier or more or 6 or more, it becomes thicker than necessary. It is unreasonable to apply.

On the other hand, in manufacturing the absorbent quick-drying yarn to set the nozzle size from 3Φ to 4Φ to produce yarn. When the flame-retardant quick-drying yarn is the same as the general absorbent quick-drying yarn, the workability of spinning is inferior and phosphorus (P) compound in the nozzle part This pass is difficult to manufacture. In view of this, in the present embodiment, the nozzle size is changed to 2Φ and the pore size of the cross section is 25% or less by changing the existing nozzle type. Expression. In this embodiment, the spinning nozzle size is 2Φ and the pore size of the cross section is reduced to 15% to improve the radioactivity of the quick drying flame retardant yarn.

In addition, the recent technical trends, but there are many attempts to manufacture a flame retardant fabric using sesame yarn, but because the large amount of phosphorus (P) is added to the sesame yarn applied to the flame retardant fabric is poor radioactivity, wool and trimming Many problems occurred during weaving, and there was a limit to development. However, in the present embodiment, in order to develop the mono-denier of the three-sum flame retardant yarn from 0.3 denier to 1 denier using the existing 80 Φ nozzle, the design of the detention is expanded on the nozzle and expanded from 80 Φ to 120 Φ to improve the radioactivity of the three-sum flame retardant yarn, and also the radiation yield. Can be improved.

Thus, by developing the three-sum flame retardant yarn applied to the car seat, the fabric of the seat cover used in the car is excellent in the post-processing and can have excellent performance in weaving and sewing.

Example 1

The seat cover of Example 1 uses a polyester copolymer absorption quick-drying flame retardant yarn for the warp yarn, and a polyester copolymer fine sum flame retardant yarn for the weft yarn. As such, when the sweat-absorbing quick-drying flame retardant yarn and sesame flame retardant yarn are used together in the seat cover, flame retardancy, absorbency, dryness, volume, and naturalness can be simultaneously satisfied.

At this time, in the present embodiment it is possible to manufacture the fabric using a conventional jacquard loom, the weft weft alternately in the warp fabric (reverse tissue) is woven on both sides. The orbital tissue refers to a tissue in which space is formed between the fabric when the fabric is woven in multiple layers.

That is, the seat cover according to the present invention is made by crossing the warp and weft yarns at right angles to each other, and forms a variety of fabric texture in accordance with the crossing method. The warp yarn refers to the warp yarn in the longitudinal direction of the fabric, and the weft yarn refers to the weft yarn in the direction woven at right angles to the warp yarn.

For example, FIG. 2 and FIG. 3 shows the basic orbital tissue applied to the present invention, wherein the orbital tissue of FIG. 2 and the orbital tissue of FIG. 3 become primary and secondary tissues, and thus the present embodiment as shown in FIGS. 4 and 5. Example fabrics can be produced. Figure 4 shows the back of the fabric made of four primary tissue, Figure 5 shows the front of the fabric made of four primary tissue.

As described above, in the present embodiment, the first and third warp yarns and the weft yarns are woven upward, and the second and the fourth warp yarns and the weft yarns are woven downward, which is repeatedly applied to the seat cover. It will give a sense of volume and softness.

Here, the four-piece tissue is alternately engraved in such a way that when the weft enters the warp, the three wefts go up the warp and one piece goes down the warp. In the manufacturing of the seat cover of the present embodiment may be manufactured in addition to the four sheets of tissue, if the four sheets or less tissue sheet is densely manufactured, the volume may be lowered, if more than four sheets of tissue increases the number of sheets As a result, there are many gaps between them, which may cause deformation during continuous use.

On the other hand, in the present invention it is possible to express a variety of colors by applying a temperature change in a multi-stage to the three-sum flame retardant yarn and the sweat-absorbing quick-dry flame retardant yarn. That is, it is difficult to dye the sesam yarn in the past because the dyeing process by the direct temperature dyeing method due to the nature of the polyester sesam yarn may cause the final yarn loss due to disproportionation of the dye or dye migration after dyeing.

However, in the present invention, this problem can be solved based on the multi-step dyeing method.

That is, in one step, the dyeing temperature starts at 40 ° C and gradually increases to 80 ° C, and then has a leveling time for 20 minutes. At this time, the polyester fiber is not dyed because the dye is difficult to stay in the molecule of the polyester when the process start temperature is 40 ℃ or less due to the tightness of its density, when the dyeing operation at 80 ℃ or more from the beginning Disproportionation may occur.

After cooling to 60 ° C. in two steps, the dye dyed in step 1 is maintained in the polyester molecule, followed by a full-scale coloring operation while heating up to 100 ° C., and having a second leveling time for 20 minutes.

Thereafter, the dyeing process is carried out in three steps up to 120 ° C., and the leveling time is 20 minutes even at 120 ° C. in the three steps. At this time, the dyeing operation may proceed to 120 ℃ or more, in this case, the phosphorus (P) component contained in the flame retardant yarn can be destroyed, thereby reducing the flame retardancy.

In the post-treatment process, it is easy to dye the three-sum flame retardant yarn by maintaining the sweat-absorbent quick-drying flame retardancy by reducing and washing at 80 ° C. Can be given.

In addition, the addition of one or two or more mixtures selected from deodorants, antifouling agents, antibacterial agents, and softening agents, which can suppress the occurrence of odors in the manufacture of the seat cover of the present invention, helps to improve the function. It is handled by a padding-method. At this time, the sweat-absorbent quick-dry flame retardant yarn has the advantage of naturally suppressing the generation of static electricity due to its own moisture absorption effect can be minimized the use of antistatic agents.

[Example 2]

Both the warp yarns and the weft yarns using polyester copolymer fine sum flame retardant yarn, and the same process as in Example 1 to prepare a seat cover. The seat cover manufactured in Example 2 has a lower absorbency and dryness than the seat cover of Example 1, but may further improve the volume.

In this case, the dyeing process is carried out in a multi-stage, and the fabric produced as described above may be given a uniform color because both the warp and weft yarns are applied with three-sum flame retardant yarn.

Example 3

Using a polyester copolymer sweat-absorbent quick-dry flame retardant yarn for both warp and weft yarn, and through the same process as in Example 1 to prepare a seat cover. The seat cover manufactured in Example 3 has a lower volume than the seat cover of Example 1, but may further improve absorbency and dryness.

At this time, if the combination of yarns in two to six combinations in order to improve the sweat-absorbing quick-drying function, the surface of the finished fabric gives a rough and bulky feeling, compared with the non-plyed yarn, It can remove gloss and give a feeling like a natural material.

Thus, according to an embodiment of the present invention, by producing a fabric by spinning a copolymer flame retardant yarn and sesame flame retardant yarn having a sweat-absorbing quick-drying characteristics and then applied to the car seat cover to reduce the flame retardancy and the user's sweat is generated quickly Can be solved.

In addition, it is possible to express a variety of colors by applying a four-step temperature change to the sweat-absorbent quick-drying flame retardant yarn and sesame flame retardant yarn, thereby contributing to the high-quality seat cover.
