Description

[0001] Fabrics having a cut loop structure, fabrication methods thereof, and products using the same [0001]

The present invention relates to a fabric having a cut loop structure, a manufacturing method thereof, and a product using the same.

Microfiber is made of three-dimensional structure of microfibers (less than 1 denier), and has numerous micro-spaces in dyeing and splitting, and is excellent in water absorption, washing power, touch feeling, and warmth. Microfiber cloths, mops, towels, and bathrobes are highly evaluated for their excellent cleaning power, fast drying properties, excellent antibacterial properties and durability. Especially, cleaning wipes made of micro-wool are absorbed more than 5 times more than normal wipes, and its efficiency and life are 7 ~ 8 times better than general mop. And is widely used.

The fabric used for the cleaning mop is usually fabricated by cutting a loop obtained by weaving a yarn so as to have a loop structure and weaving. This is because the rag made from the fabric of the uncut loop tissue is not able to catch the foreign object to be removed and the cleaning effect is reduced. In other words, a cloth made of a fabric having a cut loop structure has a cut loop structure, since foreign matter is removed between the loop and the loop cut at the time of cleaning, .

However, when a yarn is used as a microfiber in the production of a fabric for a cleaning mop having a cut loop structure, there is an advantage that the degree of scrubbing is increased at the beginning of cleaning due to microfiber, but since the thickness of the microfiber is very thin, the repulsive elasticity is low, When the microfiber absorbs water or presses the microfibers in the process of separating the microfibers, the threads are aggregated or entangled, and the frigidity is reduced to deteriorate the cleaning effect.

In order to solve the above-mentioned problem, the present inventor has proposed a method of using a synthetic fiber splittable yarn as a core yarn in Korean Patent No. 716623 and using a split type microfiber yarn as a covering yarn, And a technique for fixing the core yarn to the core yarn. When used as a cleaning tool using the fabric thus fabricated, it exhibits superior characteristics such as scrub resistance, wrinkling resistance, water absorbency, quick drying property and touch feeling as compared with a conventional cleaning tool using the other fabric. However, the technology disclosed in Korean Patent No. 716623 has a disadvantage in that the production cost of the yarn composed of the core yarn and the covering yarn is long and complicated, resulting in a high product cost and low economic efficiency.

The present invention can be manufactured by a process that is simpler and easier to handle than conventional ones, and that can significantly shorten the manufacturing time, and the fabrics produced by the process can be used for various purposes such as scrubbing property, wiping property, water absorbency, quick drying property, It is an object of the present invention to provide a fabric having a cut loop structure capable of maintaining the same or more than the conventional one.

The present invention relates to an N / P composite yarn having a total fineness of 50 to 300 denier and processed by composite spinning of split microfine yarns made of polyester and polyamide, Viscose rayon yarn having a total fineness of 100 to 300 denier, To 300 denier, is provided on a fabric having at least one surface of the fabric with a cut loop of a knitted fabric of the N / P composite yarn and a synthetic fiber yarn, using a yarn . The product using such a fabric can maintain the property such as scrubbing property, wrinkling property, water absorbency, quick-drying property, and tactile property equal to or more than conventional.

The fabric having the cut loop structure according to the present invention can be manufactured by a simple and easy process of folding and looping N / P composite yarn, viscose rayon yarn and synthetic fiber spliced yarn to improve the economical efficiency, It can be used effectively for floor cleaning of home and business, which is used to remove fine dust, hair, solid foreign matter, stains and the like from the floor and to protect the floor or to polish the floor because of excellent hiding property, water absorbency, quick drying property and touch feeling.

In addition, the fabric having the cut loop structure according to the present invention can be usefully used in various products such as mats, towels, and wooden articles including cloths and rags.

FIG. 1 briefly shows a process of forming a cut loop structure according to the present invention, wherein 10a is a loop file and 10b is a cut file.

The present invention relates to a fabric having a cut loop structure, a manufacturing method thereof, and a product using the same.

Hereinafter, the present invention will be described in detail.

At least one surface of the fabric of the present invention is a loop cut form, knitted into a pile comprising N / P composite yarns, viscose rayon yarns and synthetic fiber splitting yarns. At this time, the shapes of the loops are regularly formed at regular intervals.

As shown in Fig. 1, in the form of a loop cut, an annular loop file 10a is formed by using the above-mentioned padding (Fig. 1 (a)) and then the loop file is cut to form a cut file 10b (Fig. 1 (b)). FIG. 1 shows a cut-loop process of one side, and the present invention is not limited thereto.

The synthetic fiber dispersion yarn enhances the rebound resilience coefficient of the cut loop at the fabricated fabric, thereby improving the restoring force and elasticity. Therefore, when the manufactured fabric is used as a cleaning mop, even if the cut loops are pressed by the pressure during the cleaning process, the fabric is immediately restored, thereby preventing the cleaning efficiency from being deteriorated due to deterioration of the wrinkling property.

When the total fineness of the synthetic fiber dispersion yarn is less than 100 denier, the restoring force and the elastic force of the cut loop are not sufficiently improved. Therefore, in the course of cleaning, When the total fineness is more than 300 denier, there is a problem that scratches may be generated on the wiping surface when wiping.

The synthetic fiber dispersed yarn can be made of various known synthetic fibers including polyester yarn or nylon yarn. Preferably, the synthetic fiber dispersion yarn is preferably a polyester yarn yarn or nylon yarn yarn having excellent elasticity and restoring force.

In addition, the synthetic fiber dispersion yarn may be composed of 2 to 50 filaments. For example, currently available polyester filament yarns have a fineness of 200 denier / 10 filament, 300 denier / 10 filament, 320 denier / 8 filament, 300 denier / 6 filament, 240 denier / 12 filaments.

The N / P composite yarn is a composite spinning process of a split microfiber yarn, and serves to improve the absorbency, quick drying property and feel of the fabric. Therefore, when the fabric is used as a cleaning or bathing gown, it can provide excellent absorbency, quick drying property and touch. The fineness of the split microfiber yarn is not necessarily limited, but it is preferable to use a yarn having a total fineness of 50 to 300 deniers in view of absorbency and touch.

Here, the term "split micro-fibers" refers to those that can be divided into a plurality of micro-fibers by a chemical method or a physical method, as is well known. For example, the segmented micro-fibers may be formed by spinning a polymer of at least two components and then dividing the micro-fibers into a plurality of micro-fibers by a chemical or physical method.

Such a segmented microfine yarn can be used without limitation as commonly used in the art, and for example, polyester and polyamide can be used. As the split type micro-yarns in which the polyester and the polyamide are combined, commercially available ones can be used. For example, the split type micro-yarns composed of 70 to 80% of polyester and 20 to 30% of polyamide can be used.

Viscose rayon improves absorbency, quick drying, dyeability and texture. Therefore, when the fabric is used as a cleaning or bathing gown, it can provide excellent absorbency, quick drying property, dyeability and feel. Though the fineness of the viscose rayon yarn is not necessarily limited, it is preferable to use a yarn having a total fineness of 100 to 300 denier in view of absorbency and touch.

The viscose rayon can be obtained by appropriately treating the cellulose of a plant extracted from wood pulp to prepare a colloidal solution of viscose and then regenerating it in a yarn form. Such viscose rayon yarns can be used without limitation as those commonly used in the art, and for example, those made of soluble cellulose fibers can be used.

In addition, the present invention is characterized by a method of manufacturing a fabric having a cut loop structure using a yarn composed of the N / P composite yarn, synthetic fiber splittable yarn and viscose rayon yarn as yarn.

Specifically, the method of producing the fabric includes an N / P composite yarn having a total fineness of 50 to 300 denier and a composite yarn of split microfine yarns made of polyester and polyamide, and a viscose rayon yarn having a total fineness of 100 to 300 denier, And a synthetic fiber dispersed yarn having a total fineness of 100 to 300 denier; Knitting the yarn and weaving the loop to form a fabric; And grinding and shearing at least one surface of the fabric to produce the fabric that has been cut into the loop.

The above ply means that the N / P composite yarn, the viscose rayon yarn and the synthetic fiber splittable yarn are piled up.

After producing the warped yarn, a fabric is produced. Fabric making is to make the fabric by weaving to include looped tissue using the yarn. The inclusion of the loop structure in the fabrication of the fabric can be easily accomplished by application of techniques known in the art. For example, a fabric having a loop structure can be easily produced by knitting a yarn after knitting a yarn so that a loops are formed on the knitting machine.

Once the fabrication of the fabric is complete, one or both surfaces of the fabric are brushed and shirred to produce a fabric in the form of a loop cut.

The bristle causes a loop, and Sharing is a bristle cutter with a loop having an irregular length to a certain length, and the bristle and shear can be carried out by using a conventional radiator and a shearing machine.

According to the present invention, it is preferable that the bristles and sheaths have a cut loop length of 2 mm to 30 mm in consideration of the applied product of the manufactured fabric. That is, the length of the loosened loop can be adjusted according to the use of the fabric prepared according to the present invention, and then the shirring can be performed. For example, if the manufactured fabric is to be used as a bath for a towel or the like, the cut loop length is suitably 2 mm to 5 mm, and if the manufactured fabric is to be used for a kitchen such as a sponge or a glove, 8 mm is suitable, and when the manufactured fabric is used for mop, the cut loop length is preferably 8 mm to 15 mm.

In this way, the brushed and shirring can be used to obtain a fabric in the form of a loop cut.

In addition, the present invention may further include a step of treating the N / P composite yarn and the viscose rayon yarn with an alkali solution to improve the ability to remove foreign matter by dividing, reducing and shrinking the rayon yarn.

The step of treating the fabric with an alkali solution may be carried out at 100 to 130 ° C for 30 minutes to 60 minutes.

In the course of the treatment with an alkali solution, the polyester of the N / P composite yarn is partially hydrolyzed to produce disodium terephthalate (hereinafter referred to as "diester") and ethylene glycol (ethylene glycol) Amide (nylon) and viscose rayon yarns are divided. That is, the alkali treatment causes the N / P composite yarn to lose weight, split and shrink.

The alkali solution can be used without limitation as long as it is a conventional solution used for dividing and reducing microparticulates of the split type microparticles. For example, sodium hydroxide (NaOH) can be used.

This reduction is proportional to the alkali solution, for example, the concentration of sodium hydroxide (NaOH) and the treatment temperature, especially the treatment temperature. In the present invention, the shrinkage percentage is taken into account and the reaction is carried out at 100 to 130 ° C for 30 to 60 minutes.

After the alkali solution treatment, washing may be carried out to remove the hydrolysis by-products generated. The water washing process may be performed by spraying water on the fabric including the divided microfine yarns to remove foreign substances and then to perform refining. It is preferable that the water washing process is performed by avoiding rapid cooling and washing with warm water at 70 to 80 ° C. The refining is to remove impurities by injecting a refining agent during the flushing operation, and generally used sodium carbonate, sodium oxygen and the like can be used, and a tertiary phosphorous acid can be used if necessary for removing the DST.

In the case where the fabric prepared by the alkali solution treatment is to be post-baked, the acid treatment may be performed after refining the wash process to facilitate dyeing. The acid treatment may be carried out by adjusting the pH to 4 to 5 by using an acid treatment agent (RC Cleaning (manufactured by Hansol K.K.), which is used in a usual dyeing process.

According to the present invention, the fabrics fabricated in the fabric manufacturing step may further be dyed at a high temperature, followed by washing and drying.

The dye may be made of a polyester or a polyester and a polyamide composite microfiber dye. Examples of such dyes include dianix fla vaine xf, dianix red, and cbn xf, which are manufactured by Daisuta, a multinational company. Dyeing color can be various colors ranging from light color to dark color.

Dyeing can be carried out by adding a dispersant, a leveling agent, a fabric softener, and an antibacterial agent in addition to the dye. In addition, cloroxylenol, which has an excellent effect for removing viruses, can also be injected and stained.

The dyeing step may be carried out at 100 to 130 ° C for 30 minutes to 60 minutes. When the high-temperature dyeing is performed, the synthetic fiber splittable yarn and Viscose rayon yarn separated by a plurality of filaments can be wiped off easily with a very fine dust or hair, thereby maximizing the scrubbing and wrinkling.

Dyeing can be performed by a method of dyeing at one time, a method of dyeing polyamide and viscose rayon yarn after polyester dyeing, and a dyeing method.

If dyeing is done at one time, the dye may be consumed more than three times as compared with the method of dividing by two times, and there is a disadvantage that defective dyeing may occur. However, if dyeing is performed twice, Therefore, it is also possible to use a method of dyeing at once. When dyeing twice, the polyester may be first dyed at 130 ° C using a disperse dye, and then dyed at 100 ° C using polyamide and viscose rayon dyes. The polyamide and viscose rayon-use dyes may be disperse dyes or acid dyes.

After dyeing is completed, it is washed and then dried to obtain a dyed fabric. The washing and drying can be easily carried out by applying a method generally used in the field of dyed fabrics.

The present invention can be used for various purposes by cutting the fabric to a predetermined size and then processing it. Accordingly, the present invention provides a product obtained by processing a fabric having a cut loop structure manufactured according to the present invention.

The product may be any one selected from the group consisting of a cloth, a mop, a kitchen mat, a bath mat, a towel, a bath glove, and a dandruff removal cleaner.

For example, if the fabric produced by the present invention is cut into a predetermined size and then processed and used as a cleaning mop, the cleaning property is extremely excellent. In addition, the fabric may be used as a mat to be installed in a toilet or a kitchen, or may be used for various purposes such as golf grass. Especially when used as a mat to be installed in a bathroom or a kitchen, it can absorb the water that gets buried in the body and the water that is disturbed when washing it in the kitchen to clean the surroundings and prevent the floor from being slippery due to falling water. In the process, the rebound elasticity of the cut loop is high, and the bristles are well formed, the cushioning power is excellent, and the touch is advantageous.

These products have a simple fabrication process and short productivity time because of the short processing time.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention. Such variations and modifications are intended to be within the scope of the appended claims.
