Description

FIELD OF THE INVENTION [0001] The present invention relates to a floor material having improved fabric and purging phenomenon using an extruded yarn,

The present invention relates to a fabric woven using an extruded yarn and a floor material improved in purging phenomenon including the same.

Coated yarn fibers have been used as industrial fibers such as blinds for many years as industrial fibers that are manufactured through cannabis, weaving and tentering using a coating yarn coated with a plastic material on the core yarn. As the core raw material, a polyester material excellent in elasticity, wrinkle is not easily caught, and has shape stability and high strength is mainly used. In consideration of tensile strength and price, polyethylene terephthalate (PET) resin is widely used have. Plastic materials such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and thermoplastic polyurethane (TPU) are used as coating materials.

In particular, the fibers extruded and coated with polyvinyl chloride (PVC) on polyester yarn are excellent in elasticity, wrinkle-free, and excellent in form-sticking property, antibacterial property and color applicability, And is widely used as a fiber for a nonwoven fabric. Such coated fiber is usually manufactured by adding an extrusion coating machine exhibiting a coating speed of 300 to 1100 m / min to a high-strength PET yarn in order to secure a physical property suitable for industrial use and adding flame retardancy, flame retardancy, antibacterial property and other functions have. For example, Korean Patent Laid-Open Publication No. 2005-79896 discloses a method for producing a fabric by coating a coating material containing a plasticizer and a flame retardant together with a polymer material such as PVC on the outer surface of a polyester fiber.

However, the shrinkage ratio of the coating material is higher than that of the core yarn due to the physical tensile force applied during the extrusion coating process at the time of manufacturing or the tenter process at the time of manufacturing the coated yarn. Therefore, When cutting woven fabric fabrics, there is a fuzzing effect, which is a phenomenon in which the core material shrinks out of the coating material due to the contraction of the coating material more than the core yarn due to the potential physical shrinkage of the coating material do. Such purging phenomenon generally becomes worse over time, and thus, when used as a blind, it damages the appearance of the interior. In addition, the puddling phenomenon becomes worse because of the load applied when the flooring is used.

In order to improve such a purging phenomenon, U.S. Patent No. 7,326,661 uses ceramic fibers such as fiber glass, quartz, silica, aluminum oxide and the like instead of polyester as a core yarn The coating material is produced through the PVC resin coating, woven as a fabric, laminated, and the like. When the flooring thus produced is cut to a certain size and then rubbed with the cutting surface, the glass or ceramic component contained in the blown yarn breaks, so that the cutting surface can be easily cleaned. However, There is a problem that biological risk is caused not only for the operator but also for the user.

Korean Patent Publication No. 2005-79896 (Alkenes Co., Ltd.) 2005.08.11. U.S. Patent No. 7,326,661 (Chilewich L.L.C.) 2008.02.05.

Fabrics and Flooring

The fabric of the present invention is woven using the extruded yarn as at least one of a warp yarn and a weft yarn.

As an example, the extruded yarn may be used only as a warp yarn, or as another example, the extruded yarn may be woven using both warp and weft yarns.

When the extruded yarn having a diameter of 600 to 5,000 占 퐉 is used only as a warp yarn, an extruded yarn having a diameter smaller than this, for example, a diameter of 50 to 2,000 占 퐉, more preferably 200 to 800 占 퐉 is used . In this case, the composition of the extruded yarn as the weft can be the same or similar to the composition of the extruded yarn as the inclined yarn.

Alternatively, it can be woven using a coating yarn having a diameter of 50 to 2,000 mu m as a weft. The coating yarn usable as the weft yarn has a structure composed of a core yarn and a coating material surrounding the core yarn.

The diameter of the core yarn may be 50-500 denier and the thickness of the coating material may be 200-1000 [mu] m.

The coating yarn may cause a purging phenomenon in which the core yarn is pushed out of the coating material. Therefore, it is preferable to use a raw material resin having a small shrinkage difference between the core yarn and the coating material in order to prevent this. For example, the shrinkage ratio of the core yarn and the coating material at 165 ° C may be 5 to 20%. It is also preferred that the difference in melting point between the core yarn and the coating material is small, for example the difference may be 0 to 50 ° C.

As an example of the coated yarn, the core yarn is made of a thermoplastic resin selected from the group consisting of TPO resin, TPU resin, PVC resin and nylon resin, and the coating material may include the same thermoplastic resin as the core yarn. At this time, the diameter of the core yarn may be 30 to 1500 denier, and the thickness of the coating material may be 120 to 1,000 mu m. As the TPO resin, various TPO resins exemplified above may be used.

As another example of the coated yarn, the core yarn may comprise a polyester resin and the coating material may have a melting point difference of 0 to 50 DEG C with respect to the core yarn. For example, the polyester resin of the core yarn and / or the thermoplastic resin of the coating material may all have a melting point of 130 to 200 ° C. As a specific example of the polyester resin of the core yarn, a polyethylene terephthalate (PET) resin in which a C _3-12 alkyldiol, a C _6-12 cycloalkyldiol, a benzene-based diol or the like is copolymerized, 230 ° C and a PET copolymer resin having a melting point of 170 to 190 ° C in a weight ratio of 0.1: 99.9 to 70: 30 can be used. Specific examples of the thermoplastic resin of the coating material include polyvinyl chloride (PVC), thermoplastic polyolefin (TPO), thermoplastic polyurethane (TPU), or a mixed resin thereof. As the TPO resin, various TPO resins exemplified above may be used.

The coating yarn may contain the above-mentioned flame retardant component in an amount of 5 to 60% by weight based on the total weight of the coating yarn, and may include other additives.

The woven fabric of the present invention thus may have a thickness of 0.5 to 1.5 mm.

Examples of the weaving pattern of the fabric of the present invention include twill weave, leno weave, plain weave, satin weave, and the like (see FIG. 4).

The fabrics of the present invention are excellent in elasticity, wrinkle-free, and excellent in form-sticking property, antibacterial property, color applicability, flame retardancy, abrasion resistance, color fastness and the like.

Specifically, the fabric of the present invention may exhibit a hardness of 40 to 100 on a Shore A basis, more preferably a hardness of 40 to 80, 70, or 40 to 65, respectively. Further, the tensile strength may be 10 N or more, and the elongation percentage may be 50% or more. Also, the oxygen index value of the fabric may be more than 27 and the light fastness of the fabric may be more than grade 8.

Particularly, since the fabric of the present invention has almost no purging phenomenon at its end face when cut using a core-free extruded yarn (see FIG. 3), it can maintain excellent appearance when used as a flooring material, a blind, have. In addition, when TPO resin or the like is used as the raw material resin, the environmental friendliness of the material can be enhanced.

The bottom material according to the present invention may have a structure in which a protective film, a lining material and the like are laminated on the fabric of the present invention. For example, the bottom material comprising a thermoplastic resin such as PVC and the like A polyester film layer may be laminated. In particular, when the flooring material is composed of the outer layer of the fabric of the present invention, the texture and texture of the fabric itself can be directly felt by the user, thereby improving the aesthetics.

Further, the fabrics and flooring materials of the present invention can be recycled, for example, the fabric or the flooring material can be recycled through a kneading process in which the backing is crushed and heated.

Manufacturing method

Hereinafter, an example of a method for producing a fabric according to the present invention will be described.

a) Preparation of raw resin composition

The raw material resin (thermoplastic resin and the like) and the plasticizer (in the case of PVC) are added to the blender at room temperature in an amount of 30 to 90% by weight based on the whole composition and dispersed for 1 to 10 minutes.

The flame retardant may be added to the composition in an amount of 5 to 60% by weight based on the whole composition and dispersed for 3 to 10 minutes in order to impart flame retardancy thereto, thereby increasing the oxygen index value.

Further additives (lubricants, pigments, ultraviolet stabilizers, antimicrobial agents and other fillers) that can impart other functionality can be added. The functional additive may be prepared by mixing during extrusion compounding using a master batch. When the additive content is less than 5% by weight based on the total coating composition, the functional additive may be directly added during the dispersion of the raw resin to perform dispersion .

The extrusion compounding process can be carried out after the dispersion is finally finished. The compounding extruder is preferably an extruder equipped with a twin screw (double screw) for optimizing the dispersion of the composition. The temperature of the extruder is adjustable from 130 to 210 DEG C and the length of the cylinder is preferably 1 m or more. The dispersion-completed composition is fed into a hopper of a twin extruder and subjected to an extrusion process at a temperature of 150 to 210 ° C. The functional additives (lubricants, pigments, ultraviolet stabilizers, antibacterial agents and other fillers) in the composition can be subjected to an extrusion compounding process by adding a specific proportion to the extruder hopper using the master batch.

In addition, a flame retardant and an additive may be first processed and recycled, and a green process may be implemented using a twin extruder having a gas discharge facility in consideration of characteristics of a flame retardant sensitive to moisture and gas.

The types and amounts of the components usable in the raw resin composition are as described above.

b) Manufacture of extruded yarn

The extruded yarn can be produced by spinning the raw resin composition prepared at a temperature of 200 to 250 DEG C to a diameter of 600 to 5,000 mu m. The extruded extruded yarn can be subjected to a stretching process and can be subjected to a stretching process at a temperature of 50 to 150 ° C, for example, using roll tension or the like. The extruded product may also undergo a heat treatment at a temperature of 50 to 150 ° C.

The extruded yarn produced as described above can be used both as warp and weft yarns at the time of fabric production, or as warp yarns.

When the above-mentioned extruded yarn having a smaller diameter is used as the weft, the same procedure as above is repeated, but the extruded yarn can be manufactured by spinning at a diameter of 50 to 2,000 탆.

c) Manufacture of coated yarn

When a coating yarn having a smaller diameter is used as the weft, the core yarn and the composition of the coating material may be used to manufacture the coating yarn according to a conventional method. For example, a core yarn may be placed in an extrusion coater, and a coating composition may be coated on the yarn and wound by passing the yarn through a die nozzle of the extruder. In this case, the extrusion coater may be an extruder equipped with a single screw, a coating temperature range of 130 to 210 ° C and a temperature of 150 to 180 ° C in consideration of melting characteristics of a yarn and a coating agent. May occur. The coating speed can be 300 to 1100 m / min.

The types of components usable as the core yarn and the coating composition are as described above.

d) Fabrication of fabrics

The extruded yarn produced in the above can be manufactured into a fabric through the following canning, weaving and tentering processes.

First, an extrusion yarn having a diameter of 600 to 5,000 占 퐉 is wound on a beam as a warp (longitudinal yarn) so as to conform to the length, density, width, etc. of the designed fabric. Wind it in length.

Thereafter, as the weft, a weaving process is performed together with the warped extruded yarn using the extruded yarn or the coated yarn.

The weaving process refers to a process of making a fabric by intersecting weft yarns at right angles to the warp yarns in an oblique one strand or two strands downward according to a certain rule. In this process, a desired pattern can be expressed.

The woven product is then tentered to produce a fabric. The tenter process is one of the finishing process steps in fabric manufacturing. It is a process of fixing the width by using a tentering machine. In the tentering process, holding both sides of the fabric with pins or clips to keep a certain width in the weft direction The temperature of the tenter can be raised to 130 to 210 캜 and fixed.
