Description

Yarn, Fabrics and Products Made from the Same

The present invention relates to a yarn, a fabric and a product using the same, and more preferably, to a yarn that can be usefully used for manufacturing a cleaning fabric, and a fabric and a product manufactured using the same.

In general, microfiber is a fiber of less than 1 denier (denier), the microfiber has a three-dimensional structure and has a myriad of micro-spaces generated during dyeing and splitting, it is a material excellent in water absorption, washing power, touch feeling, and heat retention. Microfiber cloths, rags, towels, gowns, etc. have been highly regarded for their excellent cleaning power, fast drying, excellent antibacterial properties and durability. In particular, the cleaning cloth made of microfiber is absorbed and cleaned by adsorbing when it gets stuck.It has more than five times the absorption power of ordinary cotton cloth, and its efficiency and lifespan are 7 ~ 8 times better than that of general cotton cloth. Are widely used.

The fabric used for the cleaning mop is usually manufactured by knitting and knitting a yarn to have a loop structure, and using a fabric produced by cutting a loop obtained by weaving. This is because the mop made from the fabric of the uncut loop tissue is pushed away without catching the foreign material to be removed, thereby reducing the cleaning effect. That is, since the dust produced by the cloth having the cut loop structure is removed by inserting foreign matter between the cut loop and the loop during cleaning, the cloth having the cut loop structure is applied to most cleaning mops.

However, when the yarn is used as a microfiber when manufacturing a fabric applied to a cleaning cloth having a cut loop structure, there is an advantage in that the wiping property is increased at the initial stage of cleaning due to the microfiber, but because the thickness of the microfiber is so thin, elasticity and resilience are low due to its low elasticity. When the microfiber absorbs water or is pressed under pressure during the cleaning process, the threads may be present in a lumped or entangled state, and thus, the cleaning effect may be reduced.

In order to solve this problem, Korean Patent No. 929510 discloses a cleaning pile fabric in which a cut pile layer is formed of a pile yarn having a deep sheath type composite structure. Here, the pile yarn having a deep sheath type composite structure is composed of at least one core forming yarn having a single yarn fiber fineness of 5 to 55 dtex, and at least one core forming yarn having a single yarn fiber fineness of 0.01 to 2.5 dtex surrounding the core. In addition, the Republic of Korea Patent No. 716623 discloses a technology that uses a synthetic fiber divided yarn as a core yarn, and using a split microfiber yarn as a covering yarn, but by applying a split microfiber yarn to the core yarn and heat treatment and then the covering yarn is fixed to the core yarn I've done it.

When used as a cleaning tool using the fabric prepared in the above manner will exhibit excellent properties in scrubbing, jungle, absorbency, quick-drying and feel compared to the cleaning tools using other conventional fabrics.

In the above techniques, pile yarns, that is, yarns for fabric production, are manufactured by winding a covering yarn around a core yarn forming a core portion. However, in the case of manufacturing the yarn by winding the covering yarn in the center yarn as described above, the production time is long, productivity is low, and the manufacturing cost of the yarn is high, there is a problem that increases the manufacturing cost of the final fabric or product.

Therefore, the present inventors can easily manufacture after researching a yarn that can be usefully used for manufacturing cleaning fabrics, thereby greatly improving productivity and reducing costs, and in particular, manufacturing a fabric having a cut loop structure and applying it to a cleaning product. The present invention has developed a yarn that can easily catch foreign matters such as fine dust or hair, as well as maximize properties such as wipeability, jungle, absorbency, quick drying, and touch.

Therefore, the present invention can easily manufacture the yarn can not only greatly reduce the cost, but also can easily catch foreign matters such as extremely fine dust or hair when applied to cleaning products can be easily wiped, pushed, absorbent, The purpose is to provide a yarn that can maximize the characteristics such as quick-drying and tactile.

It is another object of the present invention to provide a fabric and a product manufactured using the yarn.

In order to achieve the above object, the present invention is to provide at least one first yarn of one or more fibers and at least one second yarn of one or more fibers in parallel with each other and then The yarn is manufactured by giving an inter which puts one yarn and a second yarn into one, and the fineness of the fibers of the first yarn and the fineness of the fibers of the second yarn are different from each other.

The inter may be formed at regular intervals along the longitudinal direction.

The inter may be formed at 2mm to 1m intervals.

The inter may be formed by an air inter-mingle that blows compressed air.

The fineness of the fibers of the first yarn may be 4 to 60 denier, and the fineness of the fibers of the second yarn may be 0.002 to 3.5 denier.

The total fineness of the first yarn may be 20 to 400 denier, and the total fineness of the second yarn may be 20 to 600 denier.

The first fiber may include at least one selected from the group consisting of natural plant fiber, natural animal fiber, regenerated fiber, semi-synthetic fiber and synthetic fiber.

The fiber of the first yarn may be a branched yarn.

The divided yarn may include polyester divided yarn, nylon divided yarn or rayon divided yarn.

The second yarn fibers may include at least one selected from the group consisting of rayon, polyester, polyamide, polyvinylidene chloride, and polypropylene.

The second yarn may be a split microfiber yarn or island-in-the-sea yarn, and preferably, the second yarn may be a split microfiber yarn made of polyester and nylon.

The first yarn or the second yarn may be a speaker.

In another aspect, the present invention provides a fabric produced using the yarn described above.

In another aspect, the present invention provides a product characterized in that it is made by processing the fabric.

The product may be any one selected from the group consisting of dishcloths, mops, kitchen mats, bathroom mats, towels, bath gloves and anti-dandruff cleaners.

The yarn according to the present invention is manufactured by giving an inter-core that puts a temporary yarn comprising a first yarn and a second yarn of fibers having different fineness into one along the longitudinal direction without a separate twist, Not only is the manufacturing process simple, but also significantly lowers the cost (about 60 ~ 70%) compared to the method of manufacturing the yarn by twisting the covering yarn to the existing core yarn.

As well as manufacturing a fabric having a cut loop structure using the yarn manufactured in accordance with the present invention, and manufacturing a cleaning product using the same, the first fine yarn with a large fineness, while easily catching foreign substances such as extremely fine dust or hair It can be wiped, and the second yarn having a small fineness exhibits excellent wiping property, jungle property, absorbency, quick drying property and touch.

Yarn according to the present invention can be usefully used in the manufacture of fabrics, such as woven or knitted fabrics, such fabrics can be usefully used in products such as various mats, towels, bath articles, including cloth and mop.

1 is a photograph showing the surface of the fabric prepared according to an embodiment of the present invention.

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

Yarn according to the present invention comprises at least one first yarn and at least one second yarn.

The first yarn may be one or two or more fibers. Likewise, the second yarn may be of one or more fibers.

According to the present invention, the fineness of the fibers constituting the first yarn and the fineness of the fibers constituting the second yarn are different. For example, the fineness of the fibers constituting the first yarn may be larger than the fineness of the fibers constituting the second yarn.

For example, the fineness of the fibers of the first yarn may be 4 to 60 denier, and the fineness of the fibers of the second yarn may be 0.002 to 3.5 denier. In addition, the total fineness of the first yarn may be 20 to 400 denier, and the total fineness of the second yarn may be 20 to 600 denier.

The first yarn is relatively thick in the production of a fabric having a cut loop structure using the yarn according to the present invention, thereby increasing the resilience modulus and improving resilience and elasticity. Therefore, when the fabric is used as a cleaning mop, even if the cut loop is pressed under pressure, it is recovered immediately, thereby preventing the cleaning efficiency from being degraded due to the decrease in the sliding property. In order to sufficiently exhibit the effect of the first yarn, the fineness of the fibers of the first yarn is preferably 4 to 60 denier, and the total fineness of the first yarn is 20 to 400 denier.

At this time, when the fineness of the fibers constituting the first yarn is less than 4 denier, and the total fineness of the first yarn is less than 20 denier, the restoring force and elasticity of the cut loop are sufficiently improved when fabricating the fabric having the cut loop structure using yarn. There is a drawback to not being. In addition, when the fineness of the fibers constituting the first yarn is greater than 60 denier, and the total fineness of the first yarn is greater than 400 denier, the surface that is wiped when the cotton is wiped with the product when manufactured with a fabric having a cut loop structure using a yarn There is a problem that scratches may occur.

When the second yarn is made of a fabric having a cut loop structure using a yarn according to the present invention, the second yarn has a relatively thin thickness and serves to improve absorbency, quick-drying, and feel. Therefore, when the manufactured fabric is used as a cleaning cloth, the second yarn exhibits excellent properties of absorbency, quick-drying, and feel. In order to fully exhibit such an effect as the second yarn, the fineness of the fibers of the second yarn is preferably 0.002 to 3.5 denier, and the total fineness of the second yarn is 20 to 600 denier.

If the fineness of the fibers constituting the second yarn is less than 0.002 denier, and the total fineness of the second yarn is less than 20 denier, there is a disadvantage in that the fast drying property is poor when manufacturing a fabric having a cut loop structure using a yarn. In addition, when the fineness of the fibers constituting the second yarn is greater than 3.5 denier, and the total fineness of the second yarn is greater than 600 denier, there is a problem in that the absorbency is poor and the touch is bad.

The first yarn may be made of one or two or more fibers, and in the case of two or more fibers, each of the first yarns may have the same fineness or different fineness. In addition, when the first yarn is made of two or more fibers, each may be the same material or different materials. In addition, when the first yarn is made of two or more fibers, the first yarn may be manufactured in one yarn form by giving twisted yarn or inter.

Here, the twisted yarn is twisted by combining two or more threads, and in general, the twisted yarn to the left by dividing the twisting direction in the twisting process is called the left lead or Z-yeon, and the right twisted yarn to the right or S is called. As a machine used for such a yarn, machines such as a ring twister and a plier twister are widely used.

Preferably, the first yarn fiber may include at least one selected from the group consisting of natural plant fiber, natural animal fiber, regenerated fiber, semisynthetic fiber, and synthetic fiber.

Preferably, the fiber of the first yarn may be a branched yarn. The divided yarn may be a polyester divided yarn, a nylon divided yarn or a rayon divided yarn. The divided yarn may be preferably composed of 2 to 50 filaments. For example, currently commercially available polyesters have a fineness of 200 denier / 10 filaments, 300 denier / 10 filaments, 320 denier / 8 filaments, 300 denier / 6 filaments, and 180 denier / 12 filaments for nylon Or 240 denier / 12 filaments, and the rayon branching yarn includes fineness of 200 denier / 10 filament, 300 denier / 10 filament, 320 denier / 8 filament, 300 denier / 6 filament, and the like. no.

The second yarn may be made of one or two or more fibers, and each of the second yarns may have the same fineness or may have different fineness. In addition, when the second yarn is made of two or more fibers, each may be the same material or different materials. In addition, when the second yarn is made of two or more fibers may be manufactured in one yarn form by twisting.

The second yarn fibers may include at least one selected from the group consisting of rayon, polyester, polyamide, polyvinylidene chloride, and polypropylene.

Preferably, the second yarn may be a split microfiber yarn or island-in-the-sea yarn.

Herein, divided microfiber yarns and island-in-the-sea yarns may be used without limitation, those generally known in the art. For example, the second yarn may be a split microfiber yarn made of polyester and nylon.

In order to manufacture a yarn using the first yarn and the second yarn described above, the present invention is to position at least one first yarn and at least one second yarn in parallel with each other and then the first yarn and the second yarn along the longitudinal direction It gives an inter which puts one together.

In this case, the inter may apply a method generally used in the art without limitation, for example, the inter may be formed by an air inter-mingle that blows compressed air. However, the inter may be variously modified as necessary. For example, the inter may be provided to hold the first yarn and the second yarn as one through the heat pressurization.

In this case, the inter may give an inter in the entire length direction. Preferably, the inter may be formed at regular intervals along the longitudinal direction. Preferably the inter may be formed at a 2mm ~ 1m interval. In the case of giving the inter at the interval, it is possible to easily prepare a fabric or knit fabric when manufacturing the fabric using the yarn produced.

As such, when the at least one first yarn and the at least one second yarn are placed in parallel with each other after being positioned in parallel with each other, rather than by a conventional covering method, the manufacturing process of the yarn is simple and the manufacturing cost of the yarn is centered. Compared to the method of manufacturing the yarn by twisting the covering yarn to the yarn there is an advantage that can be greatly reduced (about 60 ~ 70%). In addition, the product shows an equivalent or more effect when manufactured from a fabric having a cut loop structure that can be usefully used for cleaning using the yarn according to the present invention.

Yarn according to the present invention prepared as described above can be produced in a conventional form of fabric or knitted fabric. Preferably the yarn according to the invention can be usefully used for the production of cleaning fabrics, especially fabrics having a loop structure.

For example, using the yarn according to the present invention as a warp or weft yarn can be prepared a prefabricated fabric or knitted fabric having a loop pile. The organization of the preliminary fabric is not limited, for example, pile fabrics such as single-sided pile, double-sided pile, double velvet, and tricot knitting machine, raschel knitting machine, sinker Pile knitting, pile knitting obtained by the seal (sseal) knitting can be included.

When the preparation of the prefabricated loop structure is completed, the loop may be cut to have the cut loop structure. At this time, before the cut or after the cut, a process generally performed in the art may be added, including processes such as brushing, alkali reduction processing, and dyeing, if necessary. Figure 1 shows the surface photo of the fabric having a cut loop structure after the weight loss process and dyeing process.

Fabrics thus prepared, in particular, fabrics having a cut loop structure may be usefully used in various products. At this time, the length of the cut pile is preferably 1mm ~ 50mm. The length of the cut pile can be adjusted by adjusting the length of the loop being raised according to the use of the fabric produced and then cutting. For example, if you want to use the fabric for bathing, such as towels, the cut loop length is 2mm ~ 5mm is appropriate, if you want to use the fabric for mop cutting is 8mm ~ 25mm is suitable. .

In the cut loop, as shown in FIG. 1, the first yarn and the second yarn are irregularly disposed. The first yarn exists in a state separated into a plurality of filament yarns, and gives sufficient restoring force and elastic force. The second yarn is separated into a plurality of ultrafine filaments, which gives excellent absorbency, quick drying and feel.

The present invention provides a product obtained by processing the above fabric. The product may be any one selected from the group consisting of dishcloths, mops, kitchen mats, bathroom mats, towels, bath gloves and anti-dandruff cleaners.

For example, if the fabric produced by the present invention is cut to a predetermined size and then processed and used as a cleaning cloth, the wipeability is very excellent. In addition, the fabric can be utilized as a mat for installing in the bathroom or kitchen, or can be used for various purposes such as golf grass. In particular, when used as a mat to be installed in the bathroom or kitchen, it can absorb the moisture on the body or the dishwashing water in the kitchen to clean the surroundings and prevent the floor from slipping due to falling water. In the process, the resilience of the cut loop is high, the brushing is excellent, the cushioning force is excellent, and the touch is good.
